Railway Signal Equipment Safety Control Research

Based on the safety risk management of railway corporation, Find the root cause equipment failure. Combined with the Chengdu railway bureau signal equipment failure statistics in recent years, the failure mode and effect analysis method for railway signal equipment failure are analyzed, the existing railway signal equipment maintenance management system are studied, targeted safety control measures are put forward. The main research content of this paper are as follows:1. The railway signal equipment failure information statistical analysisCombined with the actual application situation of Chengdu railway bureau signal equipment, Identify the rail switch equipment, track circuit, signal and interlocking devices, power panel, block, column of on-board equipment big fault types, security risks of each kind of equipment failure points are summarized.2.Railway signal equipment failure effect analysisBy failure mode and effects analysis method for railway signal equipment failure mode, the cause of the problem, and the frequency of failure effect analysis, according to the severity of the fault is registered and the frequency of determines the security risk rating, set up a security risk rating matrix table.3.Railway signal equipment safety control measures are put forwardScreening high risk register card risk control link combined with the security risk rating matrix table,to adapt to the maintenance system reform plan content effective use of advanced monitoring means such as centralized monitoring equipment danger ahead of time, railway signal equipment dynamic security control measures are put forward, and constantly improve the reliability of equipment used.
