Abstract


As microelectronic technology and distributed fieldbus technology development , more and more trains using the train communication network , the progressive realization of the train control system , intelligent , networking and information technology . MVB is specially developed for the rail vehicles dedicated network with high-speed communications , real good. However, due to MVB is designed for train communication network and the development of its scope , the supplier , the economy are not as good as the CAN bus . CAN as a field device level communication bus with other bus , compared with high reliability and low cost. Therefore, it is a lot of rolling stock train communication network systems have adopted to the CAN bus and MVB form composed of heterogeneous networks . As the two buses connecting nodes MVB-CAN gateway is also more and more people 's attention. Most of our railway vehicles backbone network using the TCN bus protocol -level network using their cars MVB network protocols. Taking into account some vehicle equipment only with CAN bus interface ( eg vehicle plant in the market to purchase additional common equipment or other monitoring devices, due to price and other reasons not equipped with MVB Interface ) , this part of the monitoring equipment should be included in the compartment backbone there is MVB and CAN data communication problems. This paper studies with CAN interface equipment and MVB network interconnection issues . Based on the CAN communication protocol MVB and in-depth analysis , thereby to realize a MVB-CAN gateway designed to effectively complete the data communication between the two protocols . This article focuses on the MVB-CAN gateway system designed three parts: hardware design diagram , software design and system performance testing. Hardware design partially completed the MVB and CAN bus interface module design, and design -based gateway PCI04 bus . System initialization and bus data exchange is a key part of software design , MVB bus and CAN bus data transceiver programming software section of this article has also discussed in detail , and the system gateway performance test .
