Abstract :
This paper introduces the design method of an auto-safety detection system in railway signal lamps. This system is based on CAN bus, which connects all the signal lamps in the railway station, and it forms a networks manage system. DSP technology is applied to this system. It can test the status and security of the signal lamps in the railway station. Power line carrier is applied in the long-distance test and control system. In addition, system´s designs of the hardware and software are presented in this paper. The real-time and stability of this system satisfy the requirements in engineering.
