Embodiment approach

[0052] One implementation manner, step 602 includes: the DCS simulator of the pressurized water reactor nuclear power plant encapsulates the core data into a dynamic link library. Those skilled in the art should understand that, to achieve the purpose of encapsulation, other methods may be used, such as databases, static link libraries, and the like.

[0053] One implementation manner, step 604 specifically includes:

[0054] Step 604A: The PWR nuclear power plant DCS simulator calls the encapsulated core data through memory sharing;

[0055] Step 604B: The external system invokes the encapsulated core data through the data sharing interface.

[0056] In one embodiment, step 604 further includes: the external system generates interface-to-point information through the input-output interface in a way of mapping software and hardware; the input-output interface invokes the encapsulated core data according to the interface-to-point information. The point-to-point mapping of sof...

Abstract

The invention discloses a processing method for a backup panel interface of a pressurized water reactor nuclear power plant DCS analog machine. The method comprises the steps that the pressurized water reactor nuclear power plant DCS analog machine packages kernel data, calls the packaged kernel data through an input and output interface and exchanges the kernel data with an external system. The invention further discloses a system of the backup panel interface of the pressurized water reactor nuclear power plant DCS analog machine. As the kernel data are packaged and access to the packaged data is achieved through the input and output interface, the safety of the kernel data is improved. The data internal storage sharing and data sharing technology is adopted for data access, the kernel data are packaged, only the necessary input and output interface is supplied to be called by an IO system, and data exchange between the module and the system is completed on the premise of ensuring the safety and secrecy of the kernel data. The software and hardware point-to-point mapping mode is adopted, the difficult problem of the software and hardware matching technology is solved, requirements for hardware wiring are lowered, and efficiency is improved.

Description

technical field [0001] The application relates to the technical field of nuclear power plants, in particular to the back-up disk interface technology of a pressurized water reactor (PWR) nuclear power plant DCS simulator. [0002] Background technique [0003] Nuclear power plant DCS (Distributed Control System: Distributed Control System) simulator is mainly used for CPR1000 unit operating operator training and license examination, operating procedure verification, unit operating condition drills and nuclear power plant emergency drills and other production activities. Important training facility. [0004] For a long time, foreign simulator manufacturers have monopolized the design, manufacture and interface communication system technology of the BUP (Backup Pan: backup disk) disk interface system of nuclear power plant simulators. Taking the Daya Bay Nuclear Power Plant as an example, the BUP disks of the existing Daya Bay Simulator, Ling Ao Phase I Simulator, and Ling A...
