servo motor speed turnstiles gate likewise called gain access to wing barrier doors, which comes from the access control system, is one of the important elements of modern-day entrance and exit control. The door wings are driven by the control system and open and close automatically. The operating mode can be picked through programs settings: As soon as it is confirmed that the person going into is authorized, the door wings open instantly. It closes after a hold-up, and the hold-up time is adjustable. Typical servo motor speed turnstile barriers are divided into scissor doors (city flap barriers door) and swing doors. (1) Scissor doors are often used in rail transit, and common scissor doors are primarily utilized in subways and other places. The door wings extend from the inside of the box, which can efficiently seal the passage and play the role of gain access to control. In addition, an infrared picking up device is set up inside the door body, which can realize the purpose of "one person, one card" for people to travel through. (2) The swing door appeared behind the scissor door and comes from the 2nd generation dc brushless glass turnstile doors. Such servo motor speed turnstile gates is that the door wings run in the front and back instructions. The operation procedure is within the body's view, which is more secure. In addition, because the door wings do not require to be withdrawed into package, The designs of swing doors are more different. Due to the above qualities, swing doors are generally used in banks, corporate buildings, high-end office complex, etc. Anti-trailing function: There is a total infrared light band detection area in the channel. The switch state can be adjusted by software application according to the customer's accuracy requirements. The application of the light band to adapt to various needs avoids the shortcomings of point-type infrared detectors that are easily polluted and impacts the dependability of judgment, and can efficiently evaluate the future. Tag reader who reads the card. When the system identifies that tailgating has taken place, the system will react based upon the place of the legitimate cardholder returned by the infrared detector. After the door opening signal is sent out, there are still some unusual usages that will activate an alarm.
