Research On MVB Bus Communication Technology Of Train Control Equipment

Train communication network equipment is the vehicle equipment information monitoring process control and data communication system based on feedback,is the core of the distributed communication vehicle equipment,train vehicle equipment due to the demand of its parameters for data communication system,the establishment of the data communication system is an important means of data communication based on vehicular communication equipment.Based on the research of the theory of communication vehicle equipment to build train vehicle equipment data communication platform,through the introduction of the traction motor and the motor load simulation model build simple train communication network simulation platform.The data collected during the running process of the hardware are collected by the communication software,and the function of the train running on the locomotive operating platform is simulated.In this paper,the simulation of traction motor and load motor operation monitoring is realized,which can directly reflect the communication method of vehicle equipment status information and the network construction.This paper introduces the technology of network communication data processing,network communication layer structures,logic layer rendering technology,developed communication interface of PC and serial data transmission program using the LabVIEW software,from two aspects of hardware and software deployment is studied and the design idea is introduced,and then design the simulation program PC to PC the use of MCU as the lower computer to achieve better off action of the motor,with the use of the communication interface of MCU with the corresponding frequency converter to realize accurate control of motor movements.Finally,the serial communication system based on LabVIEW software is compiled.Through the actual program and the debugging of the experimental platform,it proves the practicability of the communication theory,and provides the ideas for engineering practiceIn this paper,combined with practical work experience,discussed and studied the following aspects:(1)the composition and working principle of the main bus communication system in the network communication of train control vehicle equipment are analyzed.(2)combined with the existing references and research materials,the composition,structure and working principle of MVB network communication system are studied.(3)the communication interface of PC and serial data transmission program using theLabVIEW software,from two aspects of hardware and software is necessary to study and design idea,and then designed a simulation program for PC to PC,using MCU as the lower computer can better achieve the breaking action of the motor use,with communication interface chip with the corresponding frequency converter to realize accurate control of motor movements.
