Design and Realization of Security Monitoring System for Speed-up Railway Crossing

In order to improve the status of security monitoring when a speed-up train is passing through a railway crossing, a system for security monitoring and information management of railway crossings was designed and realized. This system adopts a wireless communication mode with a frequency of 150 MHz and is supplied with solar energy power. By the real-time acquisition, transmission, analysis, storage and display of data and the monitoring and security alarm of running status, the functions of security monitoring and information management are realized. The system has been used at a railway crossing on the Chengdu-Chongqing railway for 2 years so far to successfully monitor over 24 thousands trains running through the railway crossing.
