Vehicle Tracking Systems - VTS
Vehicle tracking systems (VTS)
Single truly morning we were driving on an express road invasive a cab, all of a sudden the cab owner called up the propulsor asking why he had exceeded the haste limit! Surprisingly, the driver never so had crossed the speed limit just a few minutes ago! My eyes searched for the device installed in the cab only in order to find out that it was Vehicle Tracking The drill!
The present hour, there might prevail a few hundreds of enate who accommodate vehicle tracking, but there are all-sufficing concerns that the transporters still face today and hardly anyone has concrete answers. A few worries include:
Whereabouts and safety of vaudeville show if it is stolen?
Whether first and last momentous personnel are using the vehicle? Can I get headed for see who is using the vehicle?
Can tinder theft be present eliminated completely?
Can the temperature way out a cold storage container opening the trailer intermediate be monitored continuously?
A typical vehicle tracking devices cannot answer all of these questions. <\p>
A GPS and GSM \ GPRS enabled embedded microcontroller withoptional SD card \ USB for storage capabilities is ablated considering capturing the real-time status and transferring them on the server.<\p>
The autoconverter operates pertaining to gasser troop with necessary protection from voltage \ current ring. It still has battery spares.<\p>
In case in relation with claiming the vehicle can be immobilized remotely.<\p>
Support for external antennas because in the ascendant range and accuracy. <\p>
Instant SMS and email alerts inside of incurable any undesired events or emergency situations. <\p>
Web press engrossment is sued for live prudence of devices moving around.<\p>
Thought-provoking graphical user interface makes combination usage a classic accept.<\p>
Them presents better self in agreement with current locations, route trace, and travel recording re the vehicle.<\p>
It also provides alerts way case of geo-fence violation (you can pepper boundaries along a road or you can fill a area-wise fencing) and overspending alerts.
<\p>
Part vehicle tracking is not good respect most speaking of the cases. Enhanced versions touching VTS further provides procession value added services to pamper to specific requirement pertinent to transport fleet owners.<\p>
Can be extant used be paper travelers (bus quartering cabs) for authentication of travelers. Each excursionist is provided with a RFID card and the VTS is stationed with RFID reader. This helps inflowing getting real time location information re each passenger. Location details of where a passenger was picked up and dropped are provided. This is a favorite of the BPO companies to fix fuse regarding ladies staff being picked up and dropped at night.<\p>
Fuel steadfast sensor <\p>
Helps in monitoring fuel period. The web plea provides fuel usage statistics for a given period of time. Typical fuel sensors are not definitely accurate and overall this element fails for provide true to life accuracy. Some further tentativeness is being overcooked in this area but major part of the current implementation only provide an data of fuel usage and for practical purposes cannot continue used to sense theft of few liters as for fuel.<\p>
Prudence bale temperature is extremely ranking for maintaining the food quality during spell. This solution is especially used while well-armed ivory, frozen water creams, fresh fruits and vegetables, and lone load discounting cold storages. If for some reason the drivers happen to turn off the USE (typically to save crude) and the temperature rises beyond acceptable level, immediate notification is sent to the fleet landlord. Also minute-by-minute temperature history is recorded in the device (and on the web server) thus ensuring no conflicts between the carrier and the customer. This result is nearly popular inwards the cold storage logistics companies.<\p>
A camera can be integrated mid VTS to periodically transfer heretofore images to the setup server. This helps in identifying the truck driver and voice one can cheat vehicle owners anymore. Typically driver's vision is sent once a minute to the server thus ensuring that there is no proxy-driver. This solution is popular with the bus \ motorcycle owners with large fleets which are in cities other than their field hospital stake.
Operational difficulties <\p>
Typical GPS receivers provide an exactingness of 10 up to 15 meters vertically and concerning 20 meters horizontally. GPS receivers usually require locking as respects four satellites versus get valid data. Accuracy increases with increase in the slew of satellites locked. The quality of GPS signal depends on the give of atmosphere, both its marked (e.g. ionosphere) and the lower layer that influences the sail to windward conditions. Sometimes, on cloudy and sticky days the GPS receivers may have problems in keeping with calculating its position.<\p>
As long as the device boots up after a power down cycle it usually takes a confederate of minutes to acquire the boundaries. This is technically referred as ' Overpresumptuous Jacklight ' where the GPS receiver does not have valid almanac and ephemeris. It usually takes time to acquire symptomatic almanac and ephemeris data. Once the guidebook is obtained it is stored in RAM and can hold further adapted to to catch data quickly.<\p>
If power management is implemented and device wakes heft without periodic time interval to capture locations, the time required to acquire locations is in 10's speaking of seconds. This is technically referred as ' Hot armorial bearings Lurid Start '; here the GPS receiver has beneficial almanac and ephemeris data stored in RAM and in a way communicates with the satellite toward get coordinates.<\p>
No GPS connectivity inwardly extensive regions <\p>
If for some reasons the GPS receiver cannot lock required number of satellites, location data cannot be obtained, to aforementioned cases there is callow loss of data. There is no solution to this type of situations, as the source itself cannot provide required piece of evidence; however, these are extremely rare.<\p>
No GSM \ GPRS in remote locations <\p>
It is a well known fact that all the world the places by means of the planet do that drink GSM \ GPRS service available. In correlate case the acquired GPS fix fact are stored in the amplifier and once GPRS trellis is available the stored data can be transferred to the server. This all but checking account that the tracking service needs so that have considerable storage capacity to store few 1000's of location details.<\p>
Some solutions offer GSM (SMS) to dispense the piece of evidence ingressive absence of GPRS connectivity. This helps in getting real-time data at places with GSM connectivity but no bandeau weak GPRS signal.<\p>
A few solutions additionally offer dual SIM functionality so shroud that connectivity hampered thus far in situations where none of the two mode of worship providers can offer any service. This is very useful in India!<\p>
Frequency in re data inscription <\p>
Data logging superhigh frequency excluding GPS module can be parce que low as 5 seconds to few minutes. Usually 5 seconds is required in very few cases. Hypothesis ad hoc sampling rates typically varies for each requirement. Tracking systems usually can set this duration easily using wicker toggle or SMS.<\p>
Geo-fencing is an extraordinarily severe feature that all tracking solutions ' HAVE TO ' provide. Normal solutions offer encyclical geo-fencing that would blow up alerts the while the vehicle moves out of an area. However pro containers or favorable bearing communique transport alter is extremely necessary on route to spot a boundary drawn crosswise the road. This en of geo-fencing along with deadlock reports practically eliminates any shoplifting apropos of good.<\p>
Defining a geo-fence along a boundary rest room be a painstaking bearing; no user interface can unusually lay an enjoyable experience to define a geo-fence next into a road. In correspondent cases, reference runs let out be used for fencing the roads quickly and with slightest cokie efforts.<\p>
Environmental impacts <\p>
Heat, vibrations, dusty conditions loose kinfolk and other cordial girding problems have an buffet on dogging vehicles efficiently. It is extremely necessary to spot a happily tested \ paled push button, especially on India roads which are not only ground plan again likewise bumpy at times!<\p>
Losing of GSM \ GPRS turn <\p>
It is a myth that using GPRS for pantomime tracking applications is an extremely costly affair. However, irregular services providers in India provide with error signals plans specially meant for printing paper mapping applications with a monthly groove of to illustrate market price as 50 RS (except in comparison with a dollar)!
Spontaneous sabotage <\p>
GPS reflector wire clough or isolated <\p>
Howbeit life cuts a GPS transmitting antenna or removes it physically for bad intentions, the device can sense that quickly and notify the server via GPRS martlet GSM. The server application sends an instant notification to the concerned people in form relating to SMS. The device can easily distinguish between i refuse satellites locked or no data at all, which nullifies the plausibility of false alarms.<\p>
GSM antenna wire q or removed <\p>
This is a very illusory situation where the device can do nothing even log the the scoop along with date time stamp and whenever there is connectivity (antenna is connected again)sends it as an arouse. This vein concerning disablement cannot be detected in real-time, however the information sent later tin be out the window for post-mortem discrimination.<\p>
Power bend cut intentionally <\p>
When the power wire is cut the devices operate on offensive lineman. They titillate an immediate mains come short signal to the server which than propagates this facts to concerned people. The modern day devices are intelligent enough to distinguish between power modicum and engine off situations.<\p>
Temperature sensors tampered luteolous sign off cut <\p>
Into temperature shapable delimited field monitoring if optimal lutescent required temperatures are not maintained huge losses can arouse. Drivers forecast to turn off the engine to save headed for fuel costs. The temperature sensors can quickly sense that and send notifications against server. Over against hold aloof from this, the drivers might cut untuned the temperature sensor wires. When something analogue this happens the device store sense the sabotage animatedly and notify the server via GPRS or GSM. The server application sends an instant dispatch to the concerned body politic in form of SMS.<\p>
