System overview
After entering the 1980s, the highway informationization process accelerated, from the popularization of the network to the application of computer software and hardware systems, from the construction of various databases to the improvement of management systems, from the development of advanced road management systems to the establishment of travel information service systems. The highway is no longer a simple infrastructure, but is integrated into the vehicle and occupants through information technology. With the continuous development of the economy, the continuous updating and expansion of computer technology and network technology has not only accelerated the pace of the construction of expressways, but also has become increasingly demanding on the system. Implementing a high-precision, highly reliable transportation system is already a very fashionable topic. The transportation toll system is one of the four major electromechanical engineering projects of the highway. It is also the core of the domestic highway electromechanical engineering application and the greatest benefit to its use. The most mature system.
[System Requirements]
The highway toll system needs to be continuously and stably operated for a long time under the complex environmental conditions of high temperature, low temperature, humidity, electromagnetic, dust, vibration, etc. in the field. It is obviously difficult for commercial PCs to adapt to such conditions, and it is necessary to ensure that the toll system fulfills effectively. Its own charging and monitoring functions can only use industrial control computers for system control. Choose industrial chassis with more moisture-proof, dust-proof and electromagnetic-proof capabilities, and use industrial computer motherboards and industrial-grade control cards and management modules that last longer, adapt to larger temperature ranges and vibration requirements, and realize the entire system. Stable, reliable, long-term operation.

A certain company in the United States is responsible for the construction of charging systems, monitoring (security) systems, power supply lighting systems, and communication systems in a certain highway in North China through international bidding. The charging system is designed for open-ended charging. The entire charging system is divided into three levels of computer management systems, namely, the toll collection center (the management office is located in the toll building), the toll station and the toll lane. The toll center communicates data with the toll station and the toll station computer through a fiber optic transmission system. (system structure as shown below)

[System principle]
It can be seen from the upper system schematic that the entire charging system is mainly composed of three parts: the charging center management system, the toll station management system, and the lane charging system. Although we have introduced the entire charging system in three parts, the three are actually an organic whole. The toll center controls the entire toll system; the toll station collects toll lane data and transfers data between the toll center and the toll lane; the toll lane carries out correct charging for passing vehicles as required by the toll center, and uploads charging data and traffic volume Data, the three are combined with each other to form a complete charging system.
