Design And Implementation For The Signal Detecting System In Railway Terminal Subsystem

The centralized signaling monitoring system as an important part of component railway informationization, has the abilities to monitor signal equipment running status in the way of real-time,dynamic. It can save the past data in the server which could provide the live and scientific data in the signal equipment for the failure analysis.Digital data collection system is working in station terminal subsystem based on the centralized signaling monitoring system, which is based onthe CAN bus transmit date.The paper describes the system which is based on the MCS-96series single chip microcomputer for designing the process of the digital data collection, interrupt handling, program initializing, data collecting, and the resource allocating The communication protocols between the digital data collection equipment and CAN bus is defined.In the paper, the communication protocols between terminal and digital date collection equipment is defined.[30]...
