摘要
依据拖拉机上农具CAN总线和拖拉机CAN总线通信的特点,使用Motorola公司的16位单片机MC9S12XDP512对拖拉机高低速CAN总线网关进行设计,包括网关节点硬件电路的设计、监测电路的设计以及CAN总线网关控制器软件的设计。搭建测试平台,对所设计的网关进行测试,结果表明:该网关运行可靠、稳定,可正确收发CAN报文,能够实现不同CAN总线间的通信。
This paper uses the 16 bit single chip microcomputer MC9S12XDP512 from Motorola is for the design of High and Low CAN bus gateway in tractor according to the character of communication between farm implements CAN bus and tractor CAN bus.The design of gateway includes hardware circuit of gateway nodes,observation circuit and software of CAN bus gateway controller.In the end,the experimental platform is set up to verify the gateway.The experiment proves that gateway can run steadily and receive or transmit CAN signal correctly,so the gateway can achieve the function of communication between different CAN bus.
