Problems solved by technology

For the management and control of change documents, offline paper supplemented by electronic maintenance work orders is adopted, and manual management is basically the main way. The management efficiency is low, and the burden on the personnel in the change management position is relatively large.
[0006] (2) Temporary changes of multiple process systems may need to be executed or exist in the system at the same time, which brings great difficulty to work risk control. The current management method is more difficult to prevent and control cross risks
[0007] (3) Changes lead to configuration changes in the system and module status changes that cannot be known by the instrument control inspection personnel, and it takes a lot of time and cost for the inspection personnel to confirm the state deviations one by one
[0008] (4) The implementation of temporary mandatory orders cannot be effectively tracked, and it is difficult to trace when and which temporary mandatory orders were implemented in the system
[0009] (5) Procedural human error traps and high-risk operation links involved in software enforcement or change of the control system cannot be effectively identified, reminded and prevented

Embodiment Construction

[0062] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] The present invention is suitable for the change management of the control system of nuclear power plants, and specifically designs a system that realizes the online management of temporary changes in nuclear power plants, realizes the electronicization of the management and control process of temporary control changes and real-time control of the status; at the same time, it can provide the function of risk conflict detection. Integration of status data and operation status data, and assisting external knowledge base data, according to user operation requests, realizes online management of control changes, risk detection and analysis, historical data records, and displays and prompts risks on desktop and mobile terminals.

[0064] Specifically, such as figure 1 As shown, an online management system for tempor...

Abstract

The invention belongs to the technical field of a nuclear power plant control system and specifically relates to a nuclear power plant control system temporary control change online management system.The system comprises a data server, a network server and user terminals. The data server is used for analyzing DCS configuration data and DCS function drawings, generating risk rule data and storingrelated data real-time states. The network server is used for users to access interfaces, realizing a temporary control change process and carrying out data operation and call functions. All user terminals are used for accessing the network server through a company inner network, realizing functions of initiating, checking, approving and querying the temporary control change and displaying risks existing in the change within right display areas of pages of initiating, checking and approving links. According to the system, a temporary control change management process is electronized, and influences of control system configuration data module states on the operation of sets are displayed in a visual mode.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant control systems, and in particular relates to an online management system for temporary control changes of the nuclear power plant control system. Background technique [0002] At present, nuclear power plants generally use the distributed control system (DCS for short) to realize the control of nuclear power plants, because the DCS system undertakes most of the control functions of the whole plant, the configuration data of the entire DCS system is very large, and the DCS system will be comprehensively checked before leaving the factory. However, a certain number of defects in the DCS configuration may still be found during on-site commissioning and unit operation; during on-site commissioning and unit operation, control system design optimization or process system control changes are still required; The high convenience and high accessibility of the measures, there are a large number...
