【Abstract】 Based ond CAN bus the automatic railway signal lamps detecting system is presented in this paper. The DSP technology is applied to this system. It can both control and test the status and security of the signal lamps in the railway station. Power line carrier is used for carrying out the long_distance test and control. In this system, CAN bus connects all the signal lamps in the railway station, and it forms a network manage system. In addition, the system principle is described and the design of the hardware and arithmetic are presented. The experimental result indicates that real_time and stability of this system satisfies the requirements in engineering.更多还原
