Design And Implementation Of Railway Signal Monitor Fault Analysis And Diagnosis System

Along with the passenger transportation special line, increased speed sector’s rapid delaying, the railway signal domain large-scale, the high standard’s sophisticated equipment can in the big area say that the transportation safety and between the signal device service, in the time, in the technical support difficulty’s contradiction is getting more and more prominent, how to reduce the equipment failure time as far as possible, the establishment and the consummation fixed equipment service safeguard system, strengthens the equipment riding quality track management, repairs in the condition in the foundation causes the repair procedure, to repair makes repairs to the few services or the specialized centralism, realizes the equipment zero breakdown gradually, suspends the topic which urgently awaits in front of the electricity service Maintenance department to be solved.The signal microcomputer observation system is guaranteed that the traffic safety, strengthens the signal device intersection to manage, the monitor railway signal equipment utilization quality important driving equipment; Along with technical development, under Ministry of Railways organizes, the signal microcomputer monitor has revised the new engineering factor, caused the system had a more explicit request in the monitor scope and the monitor precision. Although under the new engineering factor, the signal microcomputer observation system in the surveillance, the test function had the large scale enhancement, but with realizes the equipment repair procedure, to repair the system reform, between the equipment riding quality track management function still has the big vacancy. The main performance for is low to the unit exception or the breakdown event’s real-time analysis and the diagnosis support level, lacks carries on the real-time processing to the automatic sampling data (including production to signal device’s processing opinion table) and carries on the position judgment to the breakdown (including instruction failure processing direction) the function, cannot realize the system to person’s initiative help, has not caused the signal device maintenance basis not to have the essence to change.This article analyzed through to the first floor information which gathered has carried on the deep level the excavation, used the nimble inference control strategy, the performance data statistics and the expert analyzes the method to carry on the induction, the summary and the intelligent analysis, carried on the real-time monitoring analysis to signal device’s electrical parameter, discovered that the equipment electricity parameter dropped sounds the early warning promptly, analyzed the question from an experienced signal expert’s angle, supplied the prompt effective diagnostic message for the scene electricity service attendants and solves the question direction, could simplify the service flow or the direct localization breakdown quarter, helped the signalman to discover the fault point rapidly, and carried on processing promptly, thus the reduction maintenance time, raised the service efficiency and the service level. Causes "to carry on comprehensively, real-time, the science examination monitoring to the electricity service equipment’s utilization condition, makes the preventive examination, the pointed service, before breaking down and the hidden danger control" possibly becomes.
