Along with the introduction and development of a DCS system, the DCS system becomes a main means for the operation and management of a nuclear power station unit, and the safe and reliable operation of the unit is ensured. At present, most nuclear power stations basically run more than two unit sets, each unit set uses a set of DCS system which is relatively independent, and the monitoring and control of the independent unit sets are completed through the data interaction of equipment such as upper equipment and bottom DCS field control stations.
However, for a nuclear power plant operating with two or more units, there must be an electromechanical system and other auxiliary equipment that serve multiple unit units, and the DCS systems of each unit also need to perform monitoring and control functions on the equipment of the control station of the utility system. However, for the bottom DCS field control station for collecting equipment data in the public unit, the data interaction with the upper equipment of the DCS system of each unit needs to be completed. Along with the expansion of the number of the unit units, compared with a unit DCS field control station, the same-scale control station DCS field control station needs to finish 2 times, 4 times and even more than 6 times of data processing and interaction work, if the same data processing mode of the unit DCS field control station is adopted, the load of the control station DCS field control station is increased, and the load requirement of a nuclear power DCS system is difficult to meet. If the DCS field control station of the control station does not use a point-to-point communication mode, a multicast or broadcast mode is used instead, so that a part of data transmission load can be reduced, but the design of a DCS system communication protocol is required to be changed, the network flow of other control station nodes in the ring network of the control station is increased, and the risk of network storm in the ring network is increased; meanwhile, the mode also limits that each unit set has to be completely consistent with the configuration of a field control station of the control station, and is difficult to meet the use requirements of different reconstruction times of each unit set on the field and different monitoring and control conditions of each unit set.
