摘要
为满足工业中报警系统对可靠性、抗干扰性方面的严格要求,通过分析工业中各种总线类型的应用背景,以及对目前常见报警类型进行分类,提出了一种基于CAN总线的报警网络结构。在CAN总线底层协议的基础上,设计了一种更加适用于工业报警系统的较高层CAN总线协议,分析了总线数据传输的实时性和报警信息的传输处理,搭建了该通信网络的实际硬件系统。实验论证了该设计方法的有效性。
To satisfy the strict requirements on reliability and anti-interference capability for industrial alarm system, through analyzing the ap- plicable background of various buses used in industrial areas, and classifying the common seen alarm types, the alarm network structure based on CAN bus is proposed and at the basis of the low layer CAN bus, the high layer CAN bus protocol better suitable for industrial alarm system has been designed, the real-time performance of bus data transmission and the transmission processing of the alarm information are analyzed ; the practical hardware system of this communication network is established. The experiments verify the effectiveness of this design method.
