Research On Safety And Reliability Evaluation System Of BAS System In Nanjing South Railway Station

In recent years,with the rapid development of China's high-speed railway,the quality of service for the majority of passengers of China's high-speed railway is getting better and better,high-speed railway has become the main means of transport people long-distance travel,and has an excellent reputation.In order to better ensure the safe and reliable operation of the railway station,the station environment and equipment monitoring system are put into use at high-speed railway station extensivly,the reliability evaluation of environment and equipment monitoring system of high-speed railway station is beneficial to the environment and equipment monitoring system of the maintenance and improvement,has a more important significance.This paper introduces the practical application of the environment and equipment monitoring system of Nanjing South Railway Station,analyzes the structure and function of the BAS system,including the composition of subsystems,and lays a solid foundation for the study of BAS system safety and reliability evaluation system of high speed railway,it also provides the basis for the selection of system reliability evaluation index and the establishment of reliability evaluation system.The factors influencing the reliability of the BAS system of high-speed railway station are analyzed according to the analysis of the environment and equipment monitoring system instance of the Nanjing Railway Station,according to the functional structure and information flow of the system.According to the analysis,and the factors affecting the reliability of the BAS system of the high-speed railway station are deeply analyzed,on the basis of these factors,the reliability index of the BAS system of the high-speed railway station is set up according to the method and principle,and the structure and function of the system are established according to the system reliability.By analyzing the existing reliability evaluation methods and combining with the object of this paper,the reliability of the BAS system of the high-speed railway station and the structure of the system reliability evaluation index system established in this paper,the appropriate evaluation method is selected so as to carry on the next Step evaluation,in order to improve the station through capacity,make full use of its equipment capacity and so on have certain guiding significance,so provide ideas and direction for future research.
