摘要
将CAN现场总线应用到火灾报警系统中,介绍了CAN现场总线的节点硬件电路组成、实验模拟情况,以及通信软件的设计方法。并通过选取不同距离范围的数据进行传输验证,现场与上位机之间传输的数据以及报警信息具有较高的实时性、准确性。
CAN field bus is used in fire alarm system. In this paper, we introduce the design methods of the hard circuit compositions, experimental simulation, and communication software. And we choose the different distances to examine the accuracy right of datas,the datas and alarm information which are between the PC and the field have high real-time performance and accuracy.
