Subway Train Axle Temperature Based On Infrared Temperature Measurementonline Monitoring System

Urban rail transit is the backbone of the city's comprehensive transportation mode,the various types of safety problems will directly affect the operational efficiency and safety of operation.At present,the development of city rail transit system online detection system is relatively slow,the data of train key equipment online failure phenomenon and the reasons why it is difficult to collect,can not obtain real-time vehicle operation data,there is a big risk of train operation safety.In this paper,based on the understanding of the principle and technology of infrared temperature measurement,the factors that affect the accuracy of infrared thermometer are studied.Based on the infrared temperature measurement research,according to the functions and technical indexes of shaft temperature measurement,the design of the subway train axle temperature monitoring system "," Research on structure of subway train axle temperature monitoring system ",and composed of modules of various types of equipment,infrared temperature measurement module for train axle temperature monitoring system" the research and implementation of adaptive axis temperature calculation algorithm,and based on the study of the realization of hotbox forecast method of data analysis;based on the identification,study the function and measurement system and data communication;combined with the subway inside the network,the collected data in the shared platform and vehicle network workstation the "subway train axle temperature monitoring system was applied in Nanjing metro,solves the problem of real-time monitoring of train running state,reduce the heat shaft The damage caused by the fault on the running part of the train is reduced,and the influence of the hot axle fault on the safety of the train operation is reduced...
