Embodiment

[0025] Such as figure 1 As shown, a general wayside safety platform in the field of railway signaling, including the main processing subsystem MPS, system diagnosis and maintenance subsystem SDMS, general gateway subsystem GGW and redundant network, said MPS, SDMS, GGW are respectively connected with redundant The remaining network connection, the MPS is connected to the GGW control;

[0026] The GGW transmits the input external system data to the MPS, and the MPS performs security verification after processing it, and judges whether the verification is passed. If the verification is not passed, the MPS controls the GGW to disconnect from the redundant network. The MPS sends the processing result to the GGW.

[0027] Among them, the main processing subsystem MPS is the core subsystem of the entire trackside safety platform, which realizes the sending and receiving and safe processing of safe communication data; SDMS records the running status of MPS through network communicat...

Abstract

The invention relates to a security platform beside common rail in the field of railway signals. The security platform includes a principal subsystem MPS, a diagnosis and maintenance subsystem SDMS, a universal subsystem GGW and a redundant network, wherein the MPS, SDMS, GGW is respectively connected with the redundant network, the MPS is in controlling connection with the GGW which transfers external system data input to MPS, after processing the MPS executes safety verification and decides whether the external system data can pass or not. If the verification cannot pass, the MPS controls GGW to disconnect with the redundant network; if the verification can pass, the MPS sends the processing results to the GGW. Compared with the prior art, the security platform beside common rail in the field of railway signals has the advantages of being high in reliability and security and good in expansibility.

Description

technical field [0001] The invention relates to the field of railway signals, in particular to a general trackside safety platform in the field of railway signals. Background technique [0002] With the development of urban rail transit, the demand for domestic independent research and development of rail transit operation and control systems as key equipment is increasing. At present, the CBTC control system based on wireless communication technology has gradually become the mainstream of the rail transportation control system. In the CBTC control system, the trackside safety subsystem ZC, LC, etc. are the main components of the CBTC control system. ZC and LC mainly control the normal operation of the train through communication with the on-board system of the train, and have high requirements for reliability, safety and maintainability, and the core equipment to ensure these performances is the trackside safety platform. At present, most of the wayside safety platforms us...
