[Abstract]:With the increase of the speed of the sixth train, the main trunk lines begin to run at a high speed of 200 km / h. The safety of the train operation control system is becoming more and more important, and the data communication between locomotives is becoming more and more frequent. The application of computer technology in locomotive and rolling stock is more and more. Train communication network and active control have become the indispensable key technology in high-speed train control. With the rapid development of microelectronic technology, computer technology and digital transmission technology, the demand for designing and implementing safe and stable train communication network equipment is increasing. This paper introduces the design of the hardware system of MVB and HDLC communication module based on embedded system. The system is used to realize the MVB bus data communication and HDLC bus data communication stipulated in the train communication network. The hardware platform consists of large capacity memory, high performance processor and a variety of common peripheral bus interfaces. This hardware development platform can realize the interaction of many kinds of bus data. This paper analyzes the running environment of the train, determines the temperature range of the operating environment of the hardware system, and the design of seismic resistance and lightning protection, compares the differences between different processors, and selects ARM as the core processor of the system. The hardware platform of FPGA ARM is adopted, the requirement of MVB bus and HDLC bus for hardware interface is briefly explained, the overall structure of the system and the hardware module are designed with a large number of pages. Bus interface design and hardware debugging are discussed in detail. After a lot of analysis and design work, this paper realizes the design of MVB bus and HDLC bus single board. At the same time, the system interacts with other devices through CAN bus and RS485 bus. This system has passed the project acceptance smoothly, the system work stably, the performance is reliable, each index all satisfies the request.
