introduction
Beijing Dingchuang Hengda Intelligent Technology Co., Ltd. license plate automatic recognition highway toll system uses the license plate and the user card to bind, capture the license plate and read the user card information when the vehicle passes through the toll station, and compare it to see whether the license plate and the user card are consistent. The license plate number is the only “identity” of the car. The combination of automatic license plate recognition and RFID products in the highway toll system can effectively prevent card loss, card reversal, card replacement, toll leakage and internal fraud, reducing tolls The loss of. In addition, the license plate recognition technology can also be used to solve the problem of path ambiguity and to assist in weighing tolls. The application of automatic license plate recognition products reduces the influence of human factors, improves the quality of service, and improves the capacity of toll stations and the level of operation and management.
System composition
The highway toll collection system is composed of two parts: a license plate recognition system and a toll system. The license plate recognition system can automatically detect vehicles and collect vehicle information, reducing the workload of toll collectors and improving work efficiency.

System Features
The license plate recognizer is used in the highway toll system to automatically recognize the license plate number. Different from the traditional industrial computer system, the license plate recognition instrument adopts the embedded system system with DSP as the core, the modular structure of one working unit of video all the way and the data transmission method of network and TCP/IP protocol, which can be realized without industrial computer. Automatically detect vehicles, obtain vehicle information, and send data to the system center through the network. The highway toll system that uses the LPR series license plate recognizer to collect vehicle information has the following characteristics:
Excellent recognition algorithm, intelligent dimming technology, and high recognition rate all-weather guarantee the performance of the system.
The embedded license plate recognition method works independently, does not interfere with the toll computer, and ensures the stability of the toll system.
It can realize the combination of video trigger and external trigger to avoid the license plate being blocked to the greatest extent.
Each lane equipment is relatively independent and does not interfere with each other.
Modular products, can be quickly replaced in case of failure, and the system quickly returns to normal.
