New Architecture of Monitoring Systems of Train Traffic Control Devices at Wayside Stations

In order to improve fault tolerance of train control systems different methods are applied: from hardware and software protection to the use of test facilities, self-diagnosis, intermittent and continuous monitoring of function blocks and organization units. New architecture of monitoring systems of train traffic control means was developed by the author of the article; the former makes it possible to optimize capital investments in its implementation and maintenance costs, and at the same time has all advantages of the given architecture and allows for the solution of diagnosis and technical state prediction. Architecture of the monitoring system takes into account the topology of the unit under test (a station or a railroad haul), as well as actual loading of train traffic control means for the selection of test hardware environment and testing periods.
