[Abstract]:As one of the key technologies of EMU, Train Control Network system (Train Control and Monitoring System), which is responsible for the sharing of train control, diagnosis and monitoring information, is of great significance to the safety of train operation and the comfort of passenger ride. With the development of EMU towards high speed, automation and comfort, the train control network needs to meet the new requirements of passenger information transmission and remote diagnosis, and the original train control network is limited by communication technology. It is difficult to meet the new requirements of mass data transmission. ARCNET network has the characteristics of fast, deterministic, extensible and long distance transmission. It is very suitable for real-time process control, and has been successfully used in CRH2 control network. And become an important development direction of train control network system. In this paper, by using the advanced Lab VIEW software simulation technology and Access database technology, taking the CRH2 EMU as the research object, based on the CRH2 EMU communication network topology model, the ARCNET ring network topology model of EMU formed by 2M2T is established. The process of generating, transmitting, exchanging and controlling train communication network information (such as train control, condition monitoring, fault diagnosis and so on) is simulated, and the pure software simulation of train network communication system is realized. Finally, the virtual simulation platform of EMU network communication system with independent intellectual property rights is designed and developed, which has a certain reference significance for realizing the localization of high-speed EMU control network technology. In this paper, the current situation and trend of train control network system are analyzed, and the application of ARCNET and bus in train communication network is analyzed. The technical characteristics, working principle, data transmission process and working mechanism of ARCNET network are analyzed in detail. The communication principle of ARCNET token bus and the construction and realization method of logical ring network are studied and mastered. Secondly, this paper designs and develops a emus network control simulation system composed of 2M2T, and divides the function modules of the simulation system. At the same time, the function modules of the network simulation system are defined in detail. The simulation of train level equipment is realized by using LabVIEW software. The central device simulation software, terminal device simulation software and monitor simulation software are completed, and the data interface related to Access database is defined. At the same time, the train level network communication simulation based on Window window is completed. Finally, the network control simulation system of EMU is tested on the network platform built by PC. The results show that the system can meet the requirements of train level network communication, and the simulation system developed in this paper can successfully simulate the generation and response of train control commands, collect and monitor the status of on-board equipment. The functions of fault generation and display and real-time transmission of information meet the design requirements.
