Design of vehicle detector with vehicle identification function in ETC
With the economic development, the toll collection system (ETC) has been quietly rising in our country. The toll collection system is mainly composed of three systems: communication, monitoring and charging. An important part of the reliable operation of the entire system is the vehicle detector. In the non-stop charging system, it is a sensor that detects the vehicle heading to the communication area and commands the antenna to communicate. It has the functions of entering detection, vehicle speed detection and vehicle type discrimination. It is a vehicle that detects the departure area.According to the ETC lane controller And a sensor for controlling the display of the roadside display for the vehicle, and a function for controlling the display of the subsequent vehicle, and commanding the function of the rail off.
Taking into account the performance, price, technical complexity, reliability, maintenance requirements, scope of application and other factors, our vehicle detector is based on the principle of induction coil developed.
