How to display unknown vehicles at the entrance of the community

1. The key of the road gate identification system is the identification rate. If it can't be automatically identified, it may be a quality problem of the road gate system and the identification rate is low. ?

2. Although the pixels of the surveillance camera have been greatly improved, the stained license plate and temporary license plate are still unrecognizable. ?

3. Sometimes, although it has been identified, due to the interruption of the signal output of the control door, it is still impossible to automatically lift the rod, so it is necessary to check the wiring. ?

4. The recognition system of residential gate will be affected by rain, fog, light and other factors, which will lead to different degrees of difference in the quality of recognized images, and the location of license plate is often not fixed, which will affect the recognition rate. ?

5. When the road brake was identified, the appropriate picture was not obtained, which may be caused by improper angle, too close vehicles and inappropriate lighting. ?

Treatment method:

1. If the quality problem of the gate leads to illegibility, you can temporarily ask the security room to lift the pole manually and remotely, and then report the problem to the property when you have time.

2. If it is your own reason, you need to pay attention to cleaning or replacing the fuzzy license plate, and control the recognition angle when entering the gate at ordinary times.

Principle of automatic identification system for residential doors;

Automatic identification is mainly realized by ground loop and monitoring camera. When the monitoring camera recognizes that the vehicle with the owner's license plate passes through the ground loop, it will generate inductance and transmit it to the vehicle detector. The vehicle detector will send out two sets of relay signals, one is the signal to enter the ground loop, and the other is the signal to leave. Each set has two kinds of signals, namely, long open and long closed.

In addition, the road gate generally has a ground-sensing infrared input interface. Under normal circumstances, the vehicle detection signal will be connected to the ground-based infrared data association. When the vehicle comes to the road brake, swipe the card to open the door. When the vehicle passes the active braking, it will not automatically release the brake when it encounters the ground loop. ?
