Abstract： 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.
