An interims for on-board train control equipment on the CAN bus T. Yang & Z-s. Xu Department of Communication and Control Engineering, Northern Jiaotong University, Beijing, China Abstract A design of interbus in on-board equipment of automatic train control system is discussed in the paper. Based on comparing different types of bus, dual CAN buses are used as an interbus. The cooperation mode of dual buses guarantees the messages interchanging not to be interrupted when there is a fault in the interbus. The reliability and safety of the message transmission is improved by adding a safety transmission support sub-layer to the application layer. 1 Introduction An on-board equipment of automatic train control system is a type of equipment that can secure the train safety and improve efficiency. With the increase of trunk line's train speed and density in China, a trouble of safety is hidden. So it is urgent to use a new type of on-board equipment that can ensure the trai
