摘要
为防止火灾发生时消防泵因生锈腐蚀而不能正常工作,将PLC控制技术和变频供水技术应用于消防泵巡检中,构建消防泵自动巡检系统。针对大厦消防安全问题,对消防给水系统进行了稳定性分析,完成了巡检系统设计。该系统采用西门子S7-300、西门子变频器MM430、智能仪表等,通过PROFIBUS DP总线相连构成;上位机采用WinCC组态软件开发,上位机与PLC采用MPI总线通信。研究结果表明,该系统具有可靠性高、自动化程度高、可扩展性强、运行稳定等优点,具有广泛的应用前景。
In order to prevent that fire pump cannot work because of corrosion at the time of fire occurrence,tour inspection system was developed based PLC control technology and frequency conversion technology. The fire safety problems of building and reliability of firewater supply system were analyzed to design tour inspection system.The tour inspection system was composed of Siematic S7-300,Siematic MM430 intelligent instrument,connected by PROFIBUS DP bus. The superior computer communicated with PLC based on MPI bus. Results show that the system gets good index of the high reliability, high automation, good expansibility and high stability, has a good prospect.
