System application requirements
According to the actual application of the electronic police control system, the industrial computer used needs to be able to operate in harsh environments and can guarantee continuous operation within 7*24 hours. Using Lenovo's solution, it implements the following three functions:
1. Realize the license plate recognition system. The electronic police detects the change of the magnetic flux embedded in the coil of the parking line attachment, and then triggers the trigger signal set trigger control according to other parameters of the lane (such as during the red light signal, retrograde), and photographs the illegal vehicle. Identify and store the photo on the SM card and send it to the front-end controller via RS485.
2. The front-end controller data of each intersection is transmitted to the monitoring center through the network, and related parameters of the intersection are automatically added to the violation database.
3. At the command center, the staff combined the illegal data with vehicle information in the vehicle management database to conduct illegal work and other related work.
