Abstract: In orther to solve the problem of the much production points and the large workload of control system needs to be connected in Handan Iron and steel plant, and the production process was complex, and the branch of workshop were not fully coordinated, the LabVIEW was taken as a platform to design a set of power plant on-line monitoring system, its functions included data acquisition, data storage and analysis, trend analysis, fault diagnosis and other functions. First the server of the system was designed, it was included three modules of data acquisition, data storage, data released, and then designed the client of the system, included the system setting module, signal display module, signal monitoring and analysis module. Under guarantee the efficiency of fault detection, the storage space was greatly reduced. The results show that the monitoring system was convenient early warning before malfunction immediately, and after failed, it was convenient for the engineering technical personnel to call history data, judged fault reason and analysis.
