基于CANopen设计自动消防监控

CANopen 是基于CAN(Controller Area Network)开发的应用层协议。本文在分析CANOPEN 协议的基础上，针对智能消防水炮的通信需求，着重介绍了智能消防水炮系统通信部分的设计与实现。其中主要包括智能消防水炮网络中各个节点的硬件接口的设计，节点的对象字典和通信模型的建立。并通过消防炮系统的试运行，验证了系统通信的高效性和可靠性。

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.
