Improved remote peripheral device of universal safety computer for train control system

Abstract

The present invention discloses an improved remote peripheral device of a universal safety computer for a train control system. The improved remote peripheral device comprises a secure communication intranet, a redundant secure communication network, an external device management unit and a fault tolerant and security management unit which are in communication with the secure communication intranet, and Ethernet listeners which are in communication with the redundant secure communication network. The external device management unit is electrically connected with Ethernet adapters. According to the improved remote peripheral device of the universal safety computer for the train control system, sufficient independence of each channel, module and system function is guaranteed in physical, functional and process aspects by abiding by the design principle of the difference structure; and the common cause failure is decreased through choosing different processor architectures, and meanwhile choosing different operating systems and different compilers.

Description

technical field [0001] The invention relates to a safety computer, in particular to a remote peripheral device of a safety computer of an improved universal train control system, and belongs 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...

[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
