Processing method and system for backup panel interface of DCS (Distributed Control System) analogue machine

Abstract

The invention discloses a processing method for a backup panel interface of a DCS (Distributed Control System) analogue machine. The processing method comprises the following steps: core data is packaged by the DCS analogue machine; the DCS analogue machine calls the packaged core data by an input / output interface to be subjected to data exchange with an external system. The invention further discloses a system for the backup panel interface of the DCS analogue machine. According to the processing method, the core data is packaged and the packaged data is accessed by using the input / output interface so that the safety of the core data is improved; data access adopts a data internal storage sharing and data sharing technology and the core data is packaged; only the necessary input / output interface is opened to be called by an IO (Input / Output) system; under the precondition of ensuring the safety and the confidentiality of the core data, the data exchange between a module and the system is finished; a software and hardware point-to-point mapping manner is adopted so that the difficulty of a software and hardware matching technology is overcome, the requirements on hardware wiring is reduced and the efficiency is improved.

Description

technical field [0001] The application relates to the technical field of nuclear power plants, in particular to the backup disk interface technology of DCS simulators of nuclear power plants. Background technique [0002] 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. [0003] 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 Ao Phase II Simulator in the Daya Bay Nuc...

AI Technical Summary

Problems solved by technology

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 Ao Phase II Simulator in the Daya Bay Nuclear Power Base all use foreign technologies and implementation methods, and later upgrades and spare parts procurement There is a certain dependence on foreign contractors

At the same time, these BUP disk interface systems generally have disadvantages such as complex communication mechanism, difficult point-to-point connection, high procurement cost of interface board spare parts, large floor space of cabinet equipment, difficult system operation and maintenance, high manufacturing cost and long construction period.

Domestic contractors have insufficient experience in this large-scale simulator interface system, and there are no mature technical solutions and products at present
