Description

TECHNICAL FIELD

[0001] The application belongs to the field of instrument control technology of nuclear power plants, and particularly relates to an intelligent information monitoring system and method. BACKGROUND

[0002] Traditional conventional nuclear power plants usually adopt four data types of analog AI, AO, digital DI and DO, and can realize data acquisition and device control through a DCS (Distributed Control System), so as to ensure safe and reliable operation of the power plant, and the data structure is simple. Part of special data that cannot be collected by the DCS can complete data acquisition and analysis work through a special instrument control system, and send necessary analysis results to the DCS for processing or display.

[0003] With the continuous development of instrument control and information technology, the nuclear instrument control system is also continuously updated in technology. In the aspect of architecture design, the structure of the main instrument control system is optimized, and the original DCS system is upgraded to a control system architecture of DCS+FCS; in the aspect of function bearing, the scale and function range of the power plant operation control and protection related system are further reduced, and the functions not directly participating in the power plant operation control and protection are separated from the DCS to form an auxiliary control system, so as to improve the reliability and economy of the instrument control system as a whole, and the auxiliary control system includes but is not limited to a BOP control system, a three-waste control system, a ventilation control system, etc.; in the aspect of intelligent technology application, with the development of cloud, big data, and intelligent technology, more advanced technologies are gradually deployed in the nuclear instrument control system.

[0004] The trend of the new generation of nuclear instrument control technology developing towards intelligence has been formed, and at present, in order to promote the landing of intelligent technology as soon as possible, some nuclear power plants directly adopt a dispersed and independent instrument control system to complete the upgrading and reconstruction of the original instrument control system of the nuclear power plant, without planning the functions, architecture and system as a whole. For example, the test instrument system, the containment leakage monitoring system, the pipeline leakage monitoring system and many other systems currently set in the nuclear power plant are deployed and implemented by completely independent systems. Although this method has short-term effectiveness, it is not conducive to long-term development. On the one hand, it will lead to the differential deployment of special instrument control and special monitoring systems, reduce the application convenience and standardization of the operation personnel of the nuclear power plant, and increase the front-end equipment construction and procurement costs and the difficulty and cost of the maintenance of the back-end equipment; on the one hand, it will further aggravate the data island phenomenon, and the data of the main instrument control system, the auxiliary control system and the special instrument control system are isolated from each other and cannot be shared, which limits the continuous expansion of intelligent technology; on the one hand, the dispersed and independent systems respectively configure computing, storage and human-computer interface resources, which aggravates the waste of hardware resources and increases the demand for layout space, power consumption, heat dissipation and on-site construction. These aspects are not conducive to the popularization and development of intelligent business based on data in the nuclear power plant, and how to realize the fusion of multiple data and the fusion of intelligent business systems is a problem to be solved.

[0005] The innovation of technology should not avoid network security construction. According to the State Energy Administration's No. 36 Notice on the issuance of the overall security protection scheme and evaluation specifications of the power monitoring system, the functional boundary of the nuclear power station is simple and clear, and the operation control and operation management business are respectively deployed in the production control area safety I area and the power plant management information area safety III area. With the gradual increase of the intelligent business of the new generation of nuclear power station, the safety partition of the nuclear power station is further divided into the operation control and protection area (the safety area I of the production control area of the power plant), the operation auxiliary area (the safety area II of the production control area of the power plant), the operation and maintenance support and management area (the safety III area of the management information area of the power plant). The sharing of data should be based on the premise of network interconnection, the network interconnection between the safety partitions should fully consider the network security protection level division criteria and the boundary isolation measures between the safety areas, and the network security protection is carried out to protect the network security and the data security. That is, on the basis of the requirement of the State Energy Administration's No. 36, the application of the intelligent business in the safety II area is the development trend in the future, and the previous nuclear power station is less intelligent, and the safety II area is not set and used.

[0006] Therefore, in view of the development of the operation technology of the new nuclear power plant, a kind of intelligent monitoring information system for nuclear power station is needed, which can plan the collection of multi-source heterogeneous data as a whole, provide unified computing power, storage, analysis, integration, development and management functions, carry intelligent business functions related to nuclear power operation control, operation auxiliary optimization, operation and maintenance support and management, realize data interconnection and sharing, eliminate data island, ensure data fusion and business fusion, and ensure the long-term development and iterative update of nuclear power station intelligent business.
