Universal safety computer for train control system

Abstract

The invention discloses a universal safety computer for a train control system. The universal safety computer for the train control system comprises a core host, and a radio block center (RBC) man-machine operation display unit, a temporary speed restriction server (TSRS) man-machine operation display unit, a computer based interlocking (CBI) man-machine operation display unit and a remote peripheral device which are in communication with the core host through a secure network. The core control logics of an RBC, a TSRS, CBI and a train control center (TCC) are borne in the core host; and the remote peripheral device is electrically connected with I / O ports of the CBI, an orbital electronic unit and a lineside electronic unit. According to the universal safety computer for the train control system, the core signal function logics of the CBI, the TSRS, the TCC, the RBC and the like, as well as the functions of various scheduling and management tasks, such as the scheduling of tasks of the system, monitoring over the sound condition of the system and the like are integrated, so that different functions are fulfilled at different stages by calling each signal logic.

Description

technical field [0001] The invention relates to a safety computer, in particular to a safety computer of a general-purpose train control system, belonging to the technical field of computers. Background technique [0002] The existing train control system adopts a distributed and superimposed structure, which is also a major feature of the development of the signal system. From the development of my country's train control system, it is not difficult to find that the CTCS-3 train control system is only in the CTCS-2 train control system. Basically, the ground equipment adds Radio Blocking Center (RBC), Temporary Speed ​​Restriction Server (TSRS) and GSM-R ground equipment, etc., and the on-board equipment adds GSM-R receiving module, CTCS-3 ATP security computer, etc.; although the train control system is more Advanced, with more advanced functions and technologies, but the increase in ground subsystems and vehicle-mounted subsystems has led to a more complex structure of the ...

[0002] The existing train control system adopts a distributed and superimposed structure, which is also a major feature of the development of the signal system. From the development of my country's train control system, it is not difficult to find that the CTCS-3 train control system is only in the CTCS-2 train control system. Basically, the ground equipment adds Radio Blocking Center (RBC), Temporary Speed ​​Restriction Server (TSRS) and GSM-R ground equipment, etc., and the on-board equipment adds GSM-R receiving module, CTCS-3 ATP security computer, etc.; although the train control system is more Advanced, with more advanced functions and technologies, but the increase in ground subsystems and vehicle-mounted subsystems has led to a more complex structure of the entire CTCS train control system, and a reduction in the mean time between failures of the system, which will cause more frequent failures and lead to system recovery As the time becomes longer, accidents are likely to be induced. In recent years, many major rail transit accidents occurred during equipment failures, which fully proves this point
