The supervisory center and Remote Terminal Unit (RTU) of SCADA system need for data transfer and information exchange. CANbus is recognized to be one of the most developmental Field bus in the world and is being the leader Pattern. With the features of high reliability, low cost， easy realization， thorough transparency protocol, strong expansibility and flexibility of system setting up, it has occupied the leading position in the market and is widely used in auto motive electron industry control， and intellectualized munity and so on. CAN interface can be used to the CAN bus to receive/send data to monitor and control the CAN intelligent node. iCAN series of modules according with protocol norm possess CANbus munication interface. iCAN function module is used in the DCS / SCADA based on CAN bus, collecting the signal of industrial scene and sending it to the host or remote control equipment to achieve the function of sending and receiving data. Through the iCAN experimental teaching platform， the paper analyses the structure of the CANbus work of scene and the munication protocol. Then according to the requiring of the system design,the author constituted the munication protocol of CAN bus which is based on application layer─a standard frame format。 iCAN功能模塊用在基于 CAN 總線的 DCS/SCADA 中，采集工業(yè)現(xiàn)場的信號(hào)并傳送到主機(jī)或者控制遠(yuǎn) 端設(shè)備，實(shí)現(xiàn)對(duì)數(shù)據(jù)的發(fā)送和接收。 t o str engt hen t he t r aining super vision in lar ge and m edium goods vehicle.
