Application of mapping drone in the power industry

Nowadays, with the rapid development of China's society and economy, the requirements for the stability and safety of power system operations have been greatly increased. Various types of mapping drones have been applied to our country's power systems, such as vertical take-off and landing fixed-wing drones, multi-rotors Drones, fixed-wing drones, etc. Such mapping drone products can effectively improve the quality of line inspection work and the efficiency of line inspection work.

 Due to China's vast territory, complex terrain, more hills and mountain areas, and relatively variable weather conditions, conventional methods have failed to meet the requirements of rapid and efficient development from the initial planning and construction of power grid projects to daily inspection and maintenance after completion. Surveying and mapping drones have the characteristics of high efficiency, flexibility, fast response, and low cost, and have a wide range of applications in the early survey of power, the planning and design of transmission lines, construction and construction, and later operation and maintenance.

 1. Topographic mapping of power grid engineering

 The use of fixed-wing UAVs for the topographic survey of power grid engineering can provide detailed basic information such as images and elevations for the design of topographic maps of power grid engineering as a guarantee to minimize the possibility of errors in the process of topographic map drawing and improve the topographic map. The quality and efficiency of the planning and design provide a scientific basis for the construction of the power grid project, which in turn lays a solid foundation for the safe and stable operation of the power system.

 Early surveying and mapping of a wind farm, using a drone equipped with a Sony A7R camera, a 35mm focal length, a ground resolution of 8cm, and a 1: 2000 accuracy requirement.

 1.1. Optimized Design of Transmission Lines

 Transmission line design has a large amount of fieldwork, high labor costs, low work efficiency, and low access to information. Due to terrain restrictions, it is difficult for people in certain areas to reach. It takes a long time to map flat sections and tower foundation sections; corner tower usage, house demolition The amount of vegetation and deforestation is large; the line is frequently changed in the later stage.

 Using vertical take-off and landing fixed-wing UAV technology can greatly reduce the workload in the field. The labor cost is small, which can effectively improve the work efficiency. It can measure areas that are difficult for people to reach, and provide the optimal transmission line design. And can provide a variety of data results including DOM, DSM, DEM, DLG, and true 3D models. Mountainous strip terrain survey, 9km long and 500m wide. Results include DOM (0.1m resolution) and DSM (2m grid).

 2.Drone power inspection (thermal infrared, HD camera, LiDAR)

 Most electrical equipment will show abnormal temperature rise before failure. Infrared camera can detect abnormal temperature rise of electrical equipment. It is the best fault detection method recognized in the electric power field at present. It is listed as condition maintenance work. An important part of.

 No matter day or night, FLIR thermal imaging cameras and automation software can detect potential equipment failures and safety hazards in remote monitoring stations at any time. The resulting net effect is increased reliability and reduced costs. High-voltage electrical equipment usually heats up before it fails. Using a multi-rotor drone with an infrared camera can continuously monitor high-voltage equipment, which can prevent costly failures.

UAV tilt photography technology accelerates manual mapping to become inevitable

 The widespread application of UAV tilt photography will greatly improve the operating efficiency of the surveying and mapping industry, and make the retention of geographic information data more complete and accurate.

For many years, the topographical mapping and geographic information acquisition work have mainly adopted manual operation mode, measuring and mapping people's footsteps, traversing mountains and rivers, year-round field trips, and hard work. Such field labor has problems such as high intensity, complicated procedures, time-consuming and high cost. With the development of science and technology, the surveying and mapping industry has become increasingly demanding for the accuracy and timeliness of geographic information data. Labor and time costs have also brought tremendous pressure and burden on the industry. Therefore, the surveying and mapping industry needs to be able to quickly and efficiently, Accurate solutions for obtaining geographic information and data.

The birth of UAV tilt photography technology has overturned the traditional surveying and mapping operation method. This technology acquires high-definition stereoscopic image data through low-altitude multi-lens photography of drones, automatically generates three-dimensional geographic information models, and quickly realizes the acquisition of geographic information. Features such as high efficiency, low cost, accurate data, flexible operation, and available side information can meet the different needs of the mapping industry. Greatly adjust the coordination of internal and external work of surveying and mapping, solve the work delay caused by external factors such as weather, and convert a large amount of fieldwork into internal work. The application of drone surveying and mapping greatly frees the surveying and mapping person. Labor time and reduce labor intensity in the field!

UAV tilt photography technology is widely used 

UAV tilt photography technology can not only truly reflect the situation of the ground, but also can use advanced positioning technology to embed accurate geographic information, pick up richer image information, and give users a better experience.

UAV tilt photography technology is widely used, such as major national engineering construction, disaster emergency response and treatment, land supervision, resource development, new rural and small-town construction, retention of urban village demolition data, government tax assessment, public safety, law enforcement Action, planning and development, fire protection; disaster assessment for public utilities, environmental protection, insurance for enterprises, real estate; location services for the public, Internet applications, tourism, etc. In particular, it has broad market prospects in basic surveying and mapping, land resource survey and monitoring, dynamic monitoring of land use, digital city construction, and acquisition of emergency response surveying and mapping data.

Below we introduce the advantages and functions of UAV tilt photography technology:

Feature one: Reflect the real situation around the feature. Compared to the orthophoto, the oblique image allows users to observe the feature from multiple angles, and reflects the actual situation of the feature more realistically, which greatly makes up for the lack of applications based on the orthophoto. .

Feature two: oblique image can realize single image measurement. Through the application of supporting software, it can directly perform measurements including height, length, area, angle, slope, etc. based on the resulting image, expanding the application of oblique photography technology in the industry.

Feature 3: The texture on the side of buildings can be collected for various 3D digital city applications. Using the characteristics of large-scale aerial photography, coupled with the batch extraction and texture from oblique images, can effectively reduce the 3D modeling cost of the city.

Feature four: Small amount of data and easy to publish on the network Compared with the application of huge 3D data in 3D GIS technology, the amount of data obtained by the application of oblique photography technology is much smaller. To achieve shared applications.

UAV aerial survey terrain data + BIM

In the traditional road construction scheme optimization decision-making process, the technicians often bring the design drawings to the site, survey the surrounding environment according to the topographic features, and analyze the relationship between the site topography and the design intent. Li Bin et al. based on DEM data and interpolated them to establish a topological relationship through triangulation to obtain visual terrain. Nie Qi-Detail uses a digital topographic map to divide the rule grid, and then calculates the grid point elevation based on the contour points to construct a three-dimensional terrain model. Du Yangyang and other applications of the UAV acquired data to map large-scale topographic maps and establish terrain models; Zhao Yuan applied drone oblique photography to map large-scale topographic maps of urban areas, improving the efficiency of mapping, reflecting the unmanned The machine gets the efficiency of the digital terrain.

 In the BIM application of road engineering construction, the BIM model is used to calculate the engineering quantity or to apply the collision check between the design structures. The construction environment of urban road engineering is complex, and the traffic facilities along the line and the surrounding landforms change frequently. The traditional operation mode needs to carry the drawings repeatedly to the site for reconnaissance and verification, and the efficiency is low, and it is impossible to intuitively understand whether the design structure and the surrounding environment are harmonious and beautiful. Based on this situation, it is proposed to use the UAV to acquire the aerial survey terrain and integrate it with BIM technology to create a urban road construction environment model to quickly obtain the terrain environment of the surrounding area.

Real-life presentation in the construction environment. The road design model created by BIM is matched with the real environment model obtained by UAV aerial survey to establish a three-dimensional model (referred to as “construction environment model”) that can truly reflect the spatial relationship between the design structure and the complex construction environment. Real-time, measurable, visual, traceability and other features can provide a decision-making basis for engineering construction management.

When will China be able to realize drone delivery?

In recent years, the use of drones for terminal distribution has always been a major trend in the development of the industry. Many countries and enterprises are focusing on the development and application of drones in this field. Just last month, Google Brothers Wing announced that its drone delivery business was officially launched in the United States, which not only marked the opening of the U.S. drone transport commercialization era but also meant that after that, the US part Some residents of the area will enjoy the trendy service of drones for takeaway.

 According to news released by Wing, it will mainly open drone distribution services for non-prescription drugs, snacks and health products to residents living in Fort Cristian, Virginia. At that time, the user only needs to use the mobile phone to place an order, and the delivery staff will wrap the goods and hang them on the hooks released by the drone. After the fixing is completed, no one will automatically fly to the destination and hover at the end. The order is completed in the form of airborne cargo. The whole process can be said in one go, very convenient.

This can't help but make us feel envious, but when we come back to God, we also have doubts: When using drones to take delivery, can we come true in our country?

 Before answering these questions, we first come to understand the development process of the UAV distribution service in the United States. In the United States, there are many companies that explore and try UAV distribution services. In addition to Google's Wing, Amazon, Uber, and so on. It is reported that Amazon and Uber have already planned to launch U.S. domestic drone distribution commercial services by the end of this year, but it is still a step slower than Google Wing.

 As early as a few years ago, Google Wing actually opened the test of drone delivery in Australia, Finland, and other countries. In the Australian business, Wing delivers items such as food and cold medicine, as well as popular drinks such as coffee. According to statistics, the time for delivering coffee is usually no more than four minutes. A cup of coffee is always hot from the time of release to the customer, and the delivery test is very effective.

 So in April of this year, Wing was approved by the Federal Aviation Administration (FAA) to conduct commercial cargo transportation operations in the United States. That is to say, before the opening of the U.S. drone distribution business era, its domestic enterprises have already carried out numerous tests and applications in many countries such as Australia. Because of the good results and achievements, the business has finally been promoted. Successful landing in the United States.

 The reason why the whole process can be so smooth is inseparable from the reality of the United States itself. After all, whether it is for the United States or Australia, they are all sparsely populated countries. The impact of transportation distance, cost, labor, and other factors has led to a great demand for drone distribution. At the same time, the suburban environment of the Hirose drone also gave the drones more test space, making landing development and technology upgrades more convenient.

 In contrast, China's demand for drone distribution is exactly the opposite of that of the United States, not from rural suburbs but mainly from cities. The large population and dense high-rise buildings in the city determine the difficulty of drone distribution. In the case that the technology of drone noise and the battery is not completely overcome, the distribution of drones into the city will bring convenience, as well as It will have a bad influence on residents' lives. Therefore, this determines that China's drone distribution service will not be able to land in the short term.

 In addition, because China can only carry out drone distribution testing in the sea and other environments, the effects it exhibits are also biased in urban applications, and it is not as close to the test environment as Australia and the United States. It has also caused difficulties in the distribution of commercial drones in China.

 That is to say, the reason why China's UAV distribution cannot be quickly commercialized is related to the backwardness of technology; on the one hand, it is not related to the test environment; on the other hand, it is backward with infrastructure, insufficient user demand, and insufficient industry legal norms. Perfect related. Any lack of points may cause difficulties in the delivery of drones in China.

 In view of this, we want to open the commercial era of drone transportation like the United States. It is still unrealistic in the short term. We can only wait patiently until the above various problems have not been solved.

Summary of application of drones in the power industry

Electricity is the foundation of modern social development. Timely and effective powerline inspection is very important to ensure grid security. There were numbers of challenges and difficulties during power line inspection in the past years: long transmission line, time-consuming procedures etc. Consequently, the inspection efficiency was low, the workers were placed in higher risks. In response to the above pain points, MMC UAV develops the automatic power lines inspection system with UAV. So, what can UAV technology do in the power industry? Let's take a brief introduction.

 Autonomous inspection

The drone patrolman plans the route on the high-precision line three-dimensional map prepared in advance, and applies the centimeter-level real-time positioning technology. The drone automatically patrols the designated line, and automatically detects the device through the AI and sends back the diagnostic result data. The control room provides instant access to the operation of transmission lines, ground lines, fittings, insulators, and towers. Drone power line inspections include normal inspections, fault inspections, and special inspections.

3D modeling

UAV transmission line space distance measurement technology can realize the integration of "small electric drone + microlaser range finder", by merging laser point cloud, DOM, DEM, high-definition image, multi-spectral, infrared photography, video image, etc. The data can form a visible light composite map and a laser three-dimensional model of the transmission line channel, and establish a text, visible light composite map, and a three-dimensional model "three-in-one" information base to realize real scene reconstruction and visually display the running state of the power transmission channel.

Foreign body removal

 In response to the problem of cleaning various flammable foreign materials on the high-voltage transmission line, the six-rotor UAV is used to carry the fire-breathing device, and the combustion method is used to remove foreign matter. The worker who uses the device does not need to be close to the transmission line, and can remotely remove foreign matter such as plastic film and kite line under the condition of remote control, and shorten the original obsolete time to several minutes, which not only improves the efficiency but also reduces the efficiency. Risk of safe operation.

Line erection

 In the construction process of transmission lines, the length of the corridors and the terrain are complicated. The dense forests in the valleys and rivers in the areas where the lines pass, which brings great inconvenience to the line erection, and the implementation of the project is very difficult. In order to effectively solve the contradiction between ecological environmental protection and overhead construction, it is easy to solve the problem by using the drone to display the guide rope to set up the line frame. The drone first flies over the line and applies a lightweight high-strength lead rope through each base tower, and then uses this lightweight lead rope to continuously pull the subsequent lead rope until a three-stage lead rope is pulled and the wire is erected. In this way, the high strength of the manpower display guide rope and the difficulty of landing the guide rope for the powered parachute are solved, and the tree felling of the line channel is also reduced, thereby maximally protecting the natural ecology.

Line planning

 Using the fixed-wing UAV to carry out topographic survey of power grid engineering, provide detailed basic data such as image and elevation for power grid topographic map design as a guarantee, minimize the possibility of errors in the topographic map-drawing process, and improve the topographic map planning and design. Quality and efficiency provide a scientific basis for the construction of power grid projects, and thus lay a solid foundation for the safe and stable operation of power systems. The vertical take-off and fixed-wing unmanned aerial vehicle technology can greatly reduce the workload in the field, the labor cost is small, the work efficiency can be effectively improved, the area that is difficult for people to reach can be measured, and the optimal transmission line design scheme can be provided. And can provide a variety of data results including DOM, DSM, DEM, DLG, and true 3D models. Mountainous strip terrain survey, 9km long, 500m wide, results include DOM (0.1m resolution) and DSM (2m grid).

Multiple choices of UAV patrol transmission lines

UAV powerline inspection can observe the high-voltage transmission line in the air at different angles, hovering and shooting multi-angle image and video data, which can detect the defect of the transmission line and the hidden danger of the channel quickly, intuitively, comprehensively and accurately. The investigation can obtain the best on-site information under complicated terrain and bad weather conditions, effectively compensate for the shortcomings of the traditional way of patrolling blind spots, thereby improving the working efficiency of the first-line inspection personnel.

In actual work, when using a drone to patrol a transmission line, the patrol efficiency is closely related to the operator's familiarity with the operation of the aircraft and the complexity of the environment. For example, some skilled grid employees can use their aircraft to patrol dozens of towers a day. Some employees can also use the environment to bring them the advantage of operating the aircraft to the tower on the island a few kilometers away. In contrast, some "new drivers" who have just learned to fly may need several times to complete some veteran inspection targets. This article will take the daily transmission line inspection operation as an example to analyze how to efficiently carry out the daily patrol operation of a transmission line on a section of the line.

Work machine type selection

According to different tasks and line environment, different models can be used to perform inspection tasks in different environments. For example, when using visible light patrol work in mountainous areas or coastal areas with more gusts, use the SKYLLE 1550 series such as MMC to operate the drone with high power redundancy, which can effectively reduce the flight instability of the drone due to wind resistance reduction. Status; when you need to perform infrared or nighttime special patrol work, use a dual-light infrared camera such as Thyea ZT40 or a visible light device with a fill light function such as Thyea N30L to better perform its work, and achieve good steel for the blade. Precise work results.

At the same time, early equipment inspection and preparation work is also very important. First of all, we must fully understand and understand whether the equipment we carry meets the inspection requirements, such as the matching of the number of batteries and the workload, the inspection of the battery status, etc. The flight is well prepared.

Selection of the on-site environment of the inspection line

The condition of the terrain conditions, the presence or absence of a site that allows for take-off and landing, whether the flight space has a wide field of view, and no obstruction. The route to be patrolled should be surveyed in advance (satellite map, line construction design plan, topographic map, etc.) to segment the line. Avoid the risk of losing contact and crashing when you are on a formal patrol and flying out of the remote control range.

Selection of inspection flight plan

Route planning, sequence arrangement, selection of key parts (insulators, pins or nuts, etc.) on the line tower, control of exposure compensation, control of exposure compensation, etc., and design efficient route schemes as much as possible under limited conditions.

Wire inspection height selection

Due to its gravity, the transmission line generally hangs down and is lower than the height of the tower itself. At this time, if there is a need for a flight inspection of the line, a constant follow-up recording of the required patrol line is required. At this time, the flying height of the aircraft is not at the same height as the wire, and the distance difference and 1-2 meters are superior to prevent the collision line and crash due to operational errors.

Channel inspection height selection

In the daily inspection operation, in the process of starting the operation, the working height needs to be selected above the ground line, and the aircraft can start the operation after the aircraft reaches the specified flying height to prevent the aircraft from colliding.

Selection of inspection operation radius

Affected by the characteristics of endurance and short-wave RF signals, the operating radius should not exceed 2.5km, and the battery power should be reduced to 35%-40%. It should be considered to return immediately at full speed to avoid triggering low-power forced landing, resulting in the loss of the drone.

The inspection of drones should have four principles: safety, efficiency, comprehensiveness, and speed. During the inspection, it was found that the inspection of drones was often unable to reach the ground and inspect the tower bases due to the terrain of the forest. Too low flying height will also have a significant impact on work efficiency due to the increased difficulty of flight.

Use the new fire-breathing method of MMC SKYLLE 1550 drone to remove foreign objects such as hanging plastic bags on the high-voltage line to avoid power failure. The use of manual removal of obstacles is time consuming, laborious and dangerous, and the use of drones is more time-saving and safer. Although this may damage the power cord you are trying to save, it can minimize the risk of personal injury. Drones can also handle garbage on wires that are difficult for humans to handle. more about MMC SKYLLE 1550：http://www.mmcuav.com/portfolio-items/skylle-1550/

6 fire drones rescued mountain trapped men

At 18:03 on November 2, the command center of the fire brigade of Guilin City, Guangxi Province received an alarm: a mass was trapped on an unknown mountain. The Guilin fire brigade command immediately dispatched a rescue formation, 2 fire engines and 14 commanders. Go to the scene to rescue. When arriving at the scene, due to the darkness of the weather, rescuers could not confirm the specific location of the trapped person. At 18:37, rescuers used drones to search for the specific location of trapped people. After reconnaissance by drones, they found trapped people on the top of a mountain. Due to the difficulty of steep mountain rescue, it was decided to use drones for rescue.

 At 19:08 on the 2nd, under the unified leadership of the rescue command, the fire commander and a civilian police officer carried rescue equipment and lighting equipment, hatchets, etc. to the mountains for search and rescue, until the early morning, the weather became darker and the rescuers found that there was no The road can go up. Rescuers had to go down the mountain to redeploy the rescue plan and use the loudspeakers on the heavy duty drones to scream for the trapped people and use the drone to deliver food to the trapped people.

 At 7 o'clock on the 3rd, rescuers rushed to the scene to carry out rescue. Rescuers used heavy duty drones to find a way up the mountain for the firefighters to detect the terrain and detect the location of the trapped people. At around 14:00 on the 3rd, the rescuers finally found trapped people at the top of the mountain. Firefighters and rescuers appease the trapped people and adjust their physical strength to go down the mountain. On the way down the mountain, the rescued person took the trapped person to overcome the difficult mountain road and arrived at the foot of the mountain with the trapped person at 15:52.

 It is understood that the trapped person is a middle-aged man. He wanted to go up the mountain to find wild honey. After climbing for 10 hours to the unnamed mountain top, he found that he could not find the way down the mountain. At the rescue site, the government department linked with the Chinese industrial drone manufacturer MMC, and called 6 sets of various drones on site to add strength to the smooth rescue.

UAVs move from toys to commercial use

The current hotspots in the technology circle are non-UAVs. Whether it is "breaking into" the White House or helping Wang Feng to make a headline, the exposure of drones has soared day by day, and the commercial value of the "big toys" in the new era is rapidly digging. There have been rumors recently that MI has invested in a new drone research and development team. Last week, Taobao and Yuantong joint merchants carried out drone delivery services in specific areas such as Beijing.

 With the gradual application in the field of aerial photography, express delivery, and security, the commercial value of drones is being tapped, and the heating of the drone consumer market has also made drone manufacturing companies highly regarded.

 Small things, large output value

 The drone was originally a "toy" of geeks (referring to cutting-edge technology enthusiasts), but a technology product within a niche range. As exposures increase, so does the discussion about the drone market. At the beginning of this year, 14 companies in the field of drones participated in the CES exhibition (International Consumer Electronics Show), which leads the global consumer electronics trend, including IT giants such as Intel.

 According to data from the Consumer Electronics Association, the number of civilian UAVs in the world is expected to be sold in 2015. The market size is expected to increase by 55% compared with last year, reaching 130 million U.S. dollars. In 2018, the global UAV market is expected to grow at least. One billion dollars. This market forecast also shows the value of this technology product and the prospects in this field to the outside world.

 Domestically, there are also unimaginable drone hardware manufacturers. Among them, Dajiang Innovation Technology Co., Ltd. is the most representative. According to research firm Frost & Sullivan, DJI accounts for 50% of the global small drone market share. The protagonists in the recent news that sparked discussions have received more attention from the industry. The company was founded in 2007, and its sales increased from more than 3 million yuan in 2010 to more than 800 million yuan in 2013. It is expected that there will be more than three times growth in 2014.

 In addition, domestic drone manufacturers are also favored by capital in the near future. Among them, Feifei completed a $20 million Series A financing, and Yihang Airlines also completed a $10 million Series A financing. Recently, DJI will also receive an investment of 200 million yuan from Sequoia Capital. With the financing, the valuation of these companies has also increased by dozens of times.

 "Toy" encounters policy threshold

 UAVs are beginning to gain popularity, thanks to lower manufacturing costs and improved technology. At present, consumer-grade civil drones have become a favorite for some lovers at relatively low prices.

 A DJI person admits that the four-rotor aircraft is very fun, but it has also been explored as a valuable industry outside of toys. In the transition from professional to consumer products, in addition to the important entry barrier of price, the biggest resistance is the perception from consumers.

 Huyiqiang, CEO of Haixiang Aviation Technology Co., Ltd. explained that the trend of popularization of civilian drones in the past decade has emerged as a new generation of civilian drones featuring low-cost hardware and software and modular design. However, cost and performance, reliability, and safety are contradictions that are difficult to reconcile. Civil machines are still not comparable to traditional manned aircraft with airworthiness certificates.

 "Some of the drone manufacturers who are the model aircraft have insufficient technical reserves and lack of airworthiness regulations for aircraft. Although efforts are being made to improve product reliability, security risks still exist." Huyiqiang said, policy requirements The initial airworthiness of the drone is managed according to the method of the licensed flight certificate, and the registration is required. The drone with an operating weight of more than 7 kg is required to hold the driver's certificate, but the statistics on February 9 show that the number of passengers in the current drone is A total of 244 people.

 Many people believe that the consumer drone market is in urgent need of policy guidance, and that the support of the policy will help it get rid of the toy definition and explore a broader business model. Enterprises are hoping that the application of new technologies can be quickly realized. However, if you can't find a suitable commercial scene, you will eventually get a bucket of water.

 Commercial scene extension

 “There is a voice in the industry that the commercialization of drones is only a gimmick, but in fact, the successful application scenarios exist.” Huyiqiang believes that, apart from the regulatory level, there are still defects in the technical aspects of UAVs, but some application areas such as aerial photography and aerial survey These shortcomings can be circumvented, and companies can profit margins by choosing the right commercial scenario development market.

 DJI CEO Wang Tao has said that manipulating flight models for aerial photography is a lucrative business, and will be used in almost all filming scenes with exterior scenes. The performance of Dajiang UAV in aerial photography and aerial survey has also been recognized by the market.

 UAVs are also receiving attention in the field of logistics and transportation. In fact, several major e-commerce giants such as Amazon and DHL have begun to experiment with drone logistics. For example, Amazon launched the Prime Air drone logistics program, Google acquired the drone company Titan Aerospace, and Germany approved DHL. Machine delivery. Domestically, Taobao, Yuantong and SF have also joined the ranks of UAV logistics.

 HuYiqiang said that the use of drones for cargo transportation will inevitably be achieved, but at this stage is limited by cost, and supervision still needs to be improved. Therefore, it takes several years to see the real application.

 In addition, drones can also be used in agricultural production, rescue, energy, wildlife protection, and other fields. The industry predicts that in the future, the UAV in the civilian consumer class will be more widely used, but it still needs to be polished in various aspects such as technology, enterprise, and policy.

 The company whose main business is civil drones is not very large, and it is easy to encounter development bottlenecks. In an industry that lacks effective barriers to competition and barriers, it is also difficult to create profits. UAV companies need to focus on the applicable business scenarios in order for product prices to cross the coast line.

10 areas changed due to the emergence of drones

Drones are a trendy area, and many entrepreneurs in China have begun to develop drones. The drone has been converted from civilian to civilian. The following 10 areas have changed due to the application of drones.

 Detecting oil fields

 Oil is a rare resource that is vital to human survival, but detecting oil wells is a very dangerous thing. With special sensors, professional drones are equipped with detection equipment to detect the state of the well. The staff can know whether the oil field is in the best condition and stable operation through data or images.

 Combat crime

 Police forces in some countries are already using drones to search for potential crimes. Just as a superhero will stand on the top of a building to see the city he protects, no one can travel through the city and see if there is a crime. Perhaps this would invade the privacy of some people, but it is reasonable to use a drone to deal with crimes in a timely manner. In particular, the current police drones can be installed on the detection equipment to understand the criminals' dynamics, and the arresting equipment can arrest the criminals.

 Assist in search and rescue

 Searching for missing persons in remote areas is very difficult. We often see that search and rescue personnel spend a few days searching for a person, and search and rescue personnel are also at risk during this search. Drones can pre-search in designated areas and direct search and rescue personnel to find victims or find safer paths.

 Protecting national borders

 There are military surveillance drones at home and abroad. In the past, military searches required pilots to go into battle, but now they only need to sit in the control room of the base to complete the mission. The Australian government has recently applied surveillance drones to border investigations, which can replace sea defenses to see if there are illegal immigrants or potential dangers.

 Observing wild animals

 Another interesting drone application is the protection of wildlife, especially endangered species. There are many poachers who will find ways to hunt these creatures. It is difficult to rely on people to prevent them. A group of scientists in Indonesia use drones to observe rare apes to ensure their safety and health. In the wild, the mountains are dense and the personnel observation is very inconvenient. We can use the drone to mount the thermal imaging camera and the high-definition zoom camera. For example, the Thyea ZT40 developed by MMC is a camera that integrates thermal imaging and high-definition zoom.

 Help disaster relief

 In the face of natural disasters, many times we are powerless. We can only rescue after the disaster and do our utmost to reduce losses. However, the situation in the disaster area is extremely complicated, and it is also a huge threat to the safety of rescue workers. The rise of drones has brought great convenience to emergency rescue. Now, in the world, there is no disaster relief, fire fighting, and professional drones in various industries have played an important role.

 Environmental protection

 Environmental pollution has always been a big problem, but drones may be able to prevent environmental pollution, at least, to observe environmental pollution. In some areas, drones have been used to search for criminals who throw large amounts of garbage at random, or to prevent deforestation. NASA also began using drones to observe the ozone layer.

 Changing agriculture

 Many farmers need to check their crops regularly, and they need to go out to take care of these crops no matter what the weather. UAVs with infrared sensors can observe crops and detect their growth. For a wide-ranging farm, drones are a big boost.

 Transport medical supplies

 Natural disasters and wars often require urgent medical supplies. These areas are often complex in terrain, manpower is difficult to cross, and airdrops take time. However, the drone can deliver the goods to the designated location within the first time.

 Logistics

 Online shopping makes our lives more convenient, and many areas have also launched food delivery services. Users only need to order the food they want online, and they will be sent to the door. However, it takes time to manually distribute the food, and the order placed by the user today may arrive the next day. The appearance of the drone means that the user can get the food on the same day. In China, some cities have begun attempts to send couriers and takeaways.

What can drones do in your industry?

The emergence of industrial drones has provided many conveniences for people's lives. The broad development space and the expansion of the sub-sector of the masses have made the drones penetrate into all areas of life. At the peak of the festival day, the traffic police are using drones to capture traffic violations such as illegal parking, illegal occupation of emergency lanes, illegal lane changes, etc.; firefighters use drones to search and rescue trapped people; power inspectors are using no ones. Machines detect hidden dangers; farmers are using drones to monitor farmland and predict crop yields... Flexible and intelligent airborne robots are reducing costs and increasing efficiency for more industries.

By carrying various equipments from different industries to the drone flight platform, and with various communication links, navigation systems and professional application software, the drones are gradually integrated with various industries to become the air intelligence nodes of the three-dimensional world.

As the Leading Industrial Drone Manufacturer for Commercial Drone Solutions, MMC UAV is widely used in various industries due to its stable flight performance, compatibility with a robust standardized interface, and different professional loads.

The drone has a fixed-point flight and autonomous flight mode. The drone is equipped with a high-altitude megaphone to help the traffic police to provide emergency warnings for traffic flow and emergencies during the festival, and to implement airborne warning and propaganda reminders on the congested road sections to conduct traffic violations. Discourage correction. In case of illegal drivers who do not listen to dissuasion, the ground station police officers can use the high-definition cameras equipped with drones to record or take photos for evidence, upload fixed evidence, and impose penalties.

Instead of firefighters going deep into the fire field, the drone is equipped with a high-definition camera to perform real-time back-to-back fire and terrain. The command is combined with the video image of the UAV's real-time picture transmission system to determine the location of the fire truck. , the route of water supply, and the tactical measures taken.

The traditional way of arranging, ignoring the cost of artificial and forest felling compensation, the cost of a kilometer is about 30,000-50,000 yuan, but the cost of the aircraft can be reduced by half, and the cost can be reduced to 3 in 5 minutes. About a kilometer. More critically, every year, the power industry's inspection line will have more than 100 casualties, while drones provide safety while improving efficiency.

Instead of manually visiting the farmland to check the growth status of the crops and the condition of the soil, the real-time data obtained by the drones are analyzed by technical means to obtain the best fertilization plan to achieve a win-win situation that reduces both the use of chemical fertilizers and the increase of grain yield. The purpose is to save a lot of time for farmers.

Not only that, MMC UAV will continue to have practical application cases in petrochemical, infrastructure, archaeological, photovoltaic and other industries. How to turn the drone into an efficient tool for all walks of life through technological innovation, improve work efficiency, and safe, easy-to-use, and low-cost operations that are dangerous, difficult, and even impossible in the past are issues that MMC UAV is constantly exploring.

In order to enable industry users to better master the flight skills of drones, MMC UAV established the UAV Academy, focusing on the application technology of drones in various industries, tailor-made professional courses, allowing practitioners to advanced drones. Technology applications are at work, gaining the efficiency, safety and work results of leading industries.

Rescue drone market has great potential

The drone has the advantages of easy handling, low cost, and taking off and landing at any time. In an emergency rescue incident, it can quickly penetrate the disaster site, obtain on-site image data, and avoid casualties. With the maturity of drone technology, drones have become an indispensable part of rescue operations, and have great potential and product demand in the emergency rescue market.

With the advancement of modern science, many fields have a great connection with modern information technology. Rescue drones are the product of the combination of information technology and intelligent manufacturing. Because the rescue drone has the advantages of disaster investigation, transportation materials, emergency communication, etc., it can provide multi-faceted assistance in large-scale sudden disasters, and natural disasters and accidents are generally sudden leave, which has not yet reached the forecast. And avoid, so the demand for rescue drones is still large, and the development prospects are broad.

According to the "2019-2023 Relief UAV Industry Market Depth Survey and Investment Prospect Forecast Analysis Report" released by the New World Industrial Research Center, the rescue mission faces a harsh environment and time constraints, and the rescue drone is highly efficient. With low environmental requirements, it can effectively complete various rescue activities and gain greater recognition and support in the emergency rescue industry. With the maturity of rescue drones, their implementation in rescue operations is becoming more frequent. With the rapid development of R&D and upgrade of rescue drone products, the development of the rescue drone industry will also move toward specialization in the future. The drone rescue mode will become the mainstream trend. The rescue drone is broad before its development and is expected to become the next billion-yuan market.

Modern aid should be more urgently combined with national science and technology. The developed countries have higher levels of science and technology. They should be able to rescue the rapid industry and play it faster. At present, a relatively complete industrial chain has been formed, and intelligent rescue machine has become its national development strategy. In China, the rescue intelligence started late, and the economic impact was low in the early stage, which led to slow development. With the implementation of the National 13th Five-Year Plan, China's disaster relief machinery industry received high attention. With the training of China's rescue drone support force, the establishment of a large database of drones and the introduction of relevant laws, China's aid to the UAV industry will enter a professional development and promote the development of the rescue drone industry.

According to new analysts in the industry, with the continuous development of technology and the integration of modern technology and various industries, the intelligentization of the rescue industry has become a trend, and the development prospects of rescue drones are better. However, at present, China's rescue industry system is not perfect, lack of laws and regulations, and the development of the rescue drone industry is slow. However, with the continuous improvement of the rescue industry, its requirements for the professionalization of emergency rescue drones continue to grow.
