Abstract CANopen is an application layer based on CAN(Controller Area Network). First, the structure and characteristic of CANopen protocol is analyzed in this paper. Then concerning the communication requirements of the automatic fire fight monitor, the design of the communication part of the Fire Fight Monitor is presented, which includes the hardware interface design of CAN controller, building up the object dictionary and communication model. The communication system features great efficiency and reliability confirmed by system test running.
