A Developed Real-time Tunnel Environment Monitoring System with C#

As China's mileage of Highway and urban transport tunnel extend speedily, some challenges to the safe operation of the tunnel occur. People pay more attention to the mechanical state of the traffic tunnel and the environmental problems caused by tunnels. Based on a new traffic tunnel in Henan province, the paper designed and developed a real-time monitoring system for the tunnel environment and pressure. Apparatuses such as sampling instruments, pressure transmitter, temperature sensor, wind speed sensor and the CO concentration transmission sensor were introduced. After analysis of collector KLM-4118 communication protocol, the system that displays the monitoring data with controls of Dundas Gauge vividly and visually can collect and analyze real-time monitoring data from tunnel and save them into SQL Server database after interpret the protocol. Now it has run steadily and offered great help to maintain the safety of the tunnel.
