In order to replace the traditional vehicle of point to point single communication mode, to satisfy the requirement of real-time system, to realize data sharing, the German BOSCH company has developed the CAN technology used in automobile.The use of CAN bus reduces the number of signal lines of each node, and reduces the system detects, repair costs, thus increases overall system performance. At the same time as the CAN bus has multiple master, a master multiple slave network characteristics, it constitutes a system of flexible, has stable data transmission rate, high reliability, it can satisfy the real-time requirement.CAN bus data acquisition system based on CAN bus is introduced in detail, and the characteristics of CAN bus data acquisition system hardware and software design. This paper uses S3C2440A as microprocessor, through the CAN transceiver receives role, to control the CAN controller in bus data acquisition, and datas obtained through liquid crystal or serial are displayed, not only greatly enhance the performance of the whole system, but also reduces the cost of system. Programme after minor modifications, can also be applied to the information home appliances, consumer electronics, medical research and other fields, therefore it has a broad application value.
