Abstract
In order to improve the intelligent level of maintenance management of road traffic equipment, realize the remote optimization and evaluation of traffic signal control, and promote the social application of traffic state, a traffic signal controller wireless operation and maintenance system based on 4G communication was designed. Firstly, the basic architecture of the system was built, including an interface layer connecting different equipment, a central layer managing multiple data, and a platform layer supporting various applications. Secondly, an independent wireless communication device was designed to provide multiple communication and detection functions, which can achieve compatible connection to different controllers. Thirdly, the maintenance function modules were implemented, including fault maintenance, traffic and optimization, real-time state display and other application modules. Finally, the system func⁃tions were tested by an example independent of the traffic police special network. The results show that the operation and maintenance system achieves the wireless management of controllers′ failures, enables the optimization technology to be remotely analyzed and verified, and can promote the applications of intelligent traffic.
