The system takes 10KV power supply system, toll station power distribution system, tunnel lighting ventilation and distribution system as the object of study. The main station system in the sub-center and various kinds of monitoring and control protection devices installed in the outfield are set up. Through the remote centralized monitoring function of the main station system in the sub-center, the automatic control of the outfield monitoring and control device and the self-monitoring of the host computer in situ. The automatic control function achieves the automatic management of power supply and distribution and tunnel ventilation and lighting, liberates human resources, and realizes the unattended operation of all stations in the whole system.

Highway Electric Power Monitoring System

    For the highway monitoring system with long distance and many tunnels, we adopt a three-tier framework. The first tier is divided into the main station layer, the second tier is the local monitoring host, and the third tier is the outfield protection and monitoring devices. The first tier and the second tier are combined through the ChenXiao Industrial Optical Fiber Ethernet Switch, and the second tier and the third tier are through the area. The combination of intra-domain optical fiber data network and bus data network ensures reliable, safe and fast transmission of information, establishes stable, reliable and cost-effective communication network, provides fast transmission network channel for the whole system, and configures special distribution room and 10KV switching station for long tunnels, adopts integrated workstation. Data monitoring and control, short tunnel configuration box-type substation, the use of Mayway front-end communication management machine for data monitoring and control.
