Design Of Remote Control And Remote Diagnosis For Fully Automatic Driving Urban Rail Vehicle

At present,urban rail transit is the preferred way to solve the problem of traffic congestion.It is necessary and urgent to improve the safety and reliability of rail transit system and the overall automation level of urban vehicle.Therefore,fully automatic driving has gradually become the direction of rail transit technology development in the future.The train network control and monitoring system(TCMS),which is used to realize the functions of vehicle management,monitoring and diagnosis,is the core technology to realize the full-automatic operation and remote control of vehicle.This thesis topic designs the TCMS architecture that meets the requirements of fully automatic driverless vehicle,and completes the design of remote control functions through it.At the same time,in order to improve the level of vehicle operation and maintenance,realize the remote diagnosis and rapid positioning of vehicle faults,vehicle remote diagnosis mechanism of automatic wake-up and sleep funcitons are designed in this thesis topic.So this thesis topic has an important reference role for the development of fully automatic driverless vehicle network control system and the improvement of vehicle operation and maintenance efficiency in China.The main work of this thesis topic is as follows:Firstly,starting from the background research of fully automatic driverless urban rail vehicle,this thesis analyzes the research status and development trend of vehicle control and monitoring system and vehicle fault diagnosis.Secondly,the architecture of TCMS is designed from the aspects of communication mode,network topology,system configuration and redundancy design.Then,the requirements of the remote control functions of the fully automatic driverless vehicle are analyzed.ST language is used to complete the development of remote control functions such as automatic train wake-up,automatic sleep,air conditioning control,lighting control and remote fault reset on ISa GRAF development platform.At the same time,the preparation and testing of functional test cases are completed.Finally,combing the logic of vehicle automatic wake-up and automatic sleep control function,the remote diagnosis mechanism of this function is designed to realize the remote diagnosis and rapid positioning of vehicle faults..The design of vehicle remote control function and remote diagnosis mechanism has good theoretical research significance and practical value for the development of fully automatic driverless urban rail vehicle in China.
