AI Technical Summary

Technical Problem

The existing management of personnel access to radiation control areas in nuclear power plants is inefficient, has loopholes in control, fragmented processes, insufficient intelligence, high risks associated with the borrowing and returning of dosimeters, and prominent information silos.

Method used

By employing multimodal authentication, RWP differentiated intelligent verification based on personnel type, and hardware-level mandatory linkage between dosimeters and lockers, the system achieves closed-loop management of data throughout the entire process. It adopts parallel and selectable facial recognition and national cryptographic card verification paths, combined with real-time verification by the KZC system, to ensure the timeliness and accuracy of permissions, and to achieve persistent storage of the three-element binding relationship between dosimeters and lockers and real-time monitoring of hardware status.

Benefits of technology

It improved the safety and efficiency of access management in nuclear radiation control areas, ensured 100% return of dosimeters, achieved system-level robustness and high-reliability operation and maintenance, solved the management loophole of dosimeters being borrowed and not returned, and optimized passage efficiency.

Abstract

The invention provides an intelligent distribution linkage cabinet control method and system for a nuclear radiation control area, and the method comprises the steps: receiving an operation request initiated by a user on distribution equipment, and completing the user identity verification and the real-time verification of the access authority of the nuclear power plant control area through a mode; judging the personnel type, and verifying the effectiveness of the radiation work license and the matching between the working area and the entrance of the current control area according to a first preset rule corresponding to the personnel type; distributing and activating a personal dosimeter for the user, establishing a logic binding relationship between a unique identifier of the dosimeter, user identity information and a specified locker, and sending an unlocking instruction when it is confirmed that the dosimeter is taken away by the user through hardware perception; and when the user initiates a return operation and passes identity recheck, the bound locker is unlocked, and the binding relationship is released. According to the invention, systematic improvement of access management of the nuclear radiation control area in safety, efficiency and intelligent level can be realized.
