Metro Vehicle Detection And Control System(TCMS)Research

With China's rapid economic development,population growth,urban expansion,urgently need to establish a fast,perfect the system of urban rail transit.Rail transit system has a fast speed,large capacity,high efficiency and low pollution and other unique advantages.In urban comprehensive transportation system,the construction of urban subway and light rail system is the key point of the development of the city,in 2004,the approved presided over the ministry of railways under the state council of China railway medium and long-term planning,which clearly put forward in 2020,will build a 100000 km operating lines of mainline rail network in China,urban rail transit in our country has entered a rapid development era.As urban rail transit construction and the rapid development of communication technology,various applications in communication technology and application of urban rail transit operation way also has a growing,there are many meet different application requirements of new technology,new mode.Rail transit,on the basis of the analysis of functional requirements,combined with their own actual situation,choose the appropriate communication system model.In this paper,the function of this TCMS system of Nanjing Metro Line 3 vehicle is introduced and studied,and the accuracy of the monitoring and control of the whole train system by TCMS is researched and analyzed in the process of train running.Signal and digital signal input and output monitoring to ensure effective and safe operation of the train line.Through the train running in the test line environment through the network at all levels of TCMS system monitoring and control of the simulation experiments,and the use of PC-based platform to achieve data transmission with the train network to monitor the various indicators to determine whether to meet Train operating conditions required under a variety of conditions.And through the actual operation encountered in the case of TCMS on the failure of the system in the run-time data analysis,so as to achieve the purpose of monitoring.
