基于PROFIBUS协议的工业电气火灾监控系统

Electrical Fire Monitor System in Industry Based on PROFIBUS Protocol

针对工业智能控制系统的发展要求,提出了一种基于PROFIBUS协议的工业电气火灾监控系统的设计方案。采用模块化思想将整个系统分为监控器和协议转换模块,给出了主要的硬件电路图及软件流程,并用组态软件WINCC和STEP7设计了上位机人机界面。实际运行结果验证了设计的可行性,表明该系统的可靠性高,实时性强,扩展性能好。

The design of an electrical fire monitor system in industry base on the PROFIBUS protocol was proposed, according to the demands of intelligent control system in industry. Modularization was adopted in this design and the whole system was divided into two module, monitor and protocol conversion respectively. The main circuit diagram of hardware and software was given and the human-machine interface of monitor system was designed by using configuration software of WINCC and STEP7 in this paper. The practical run result has proved the design was feasible, the system was reliable and timely and it had good extensibility.
