Management Situation and Trend Analysis of DCS Network Maintenance in Nuclear Station

The structure of non-security DCS network of the first stage in Fangchenggang nuclear station is analyzed, and the function of network management software to the DCS network management is studied. The situation of preventive maintenance and corrective maintenance of DCS network and the trend of the future DCS network maintenance management are analyzed. The complicate DCS network need the network management software to assistant the maintenance personnel accomplish the management of network topology, device monitoring and maintenance,fault collecting,warning management and network performance management,which realize the unified management of DCS network and help the maintenance personnel to grasp the healthy status of the network, to analyzed the fault and to find the source of the fault. The usage of the network management software to manage the DCS network in nuclear station is the trend of DCS network management.
