A nuclear power plant radiation control area access monitoring system

Abstract

The invention relates to an access monitoring system for a radiation control area of ​​a nuclear power plant, comprising a central server layer, a sub-server layer, a workstation layer, and a hardware equipment layer, and a set of sub-server layers and workstation layers are respectively set in the radiation control area in each construction period and equipment at the hardware equipment layer; the hardware equipment layer includes personal dose monitoring and management equipment modules, personal surface pollution monitoring equipment modules, plant exit personnel vehicle monitoring equipment modules, and health care physical monitoring equipment modules. For the corresponding workstation, each equipment module uploads the monitoring data to the corresponding workstation; the workstation uploads the processed data information to the corresponding sub-server, and each sub-server uploads the data information to the central server for summary processing. The invention is applicable to the monitoring and management of individual doses of the whole site in a multi-pile plant site constructed in stages, and solves the problems of complex data interfaces of hardware equipment and incompatibility of control.

Description

technical field [0001] The invention belongs to the design technology of an access monitoring system for a control area, and in particular relates to an access monitoring system for a radiation control area of ​​a nuclear power plant. Background technique [0002] In nuclear power plants, health entrances and exits are generally set up in the radiation control area, and a series of control equipment and radiation monitoring equipment are used to form a control area access monitoring system to monitor the radiation workers entering and leaving the radiation control area and monitor the radiation work. Real-time monitoring and management of the dose exposure of personnel in their daily work. [0003] The control area access monitoring system generally consists of the following equipment: [0004] - Personal dose monitoring and management network: [0005] ·Central server [0006] ·System Workstation [0007] Electronic Personal Dosimeter ("EPD" for short) [0008] ·Dosime...

AI Technical Summary

Problems solved by technology

However, at present, there are many brands and models of equipment for individual dose monitoring and management between each stack in a multi-stack site, and the hardware data types and control interfaces are complex. To achieve unified monitoring and management of dose in the whole plant, the traditional system structure needs to be changed

For example, "Nuclear Power Plant Control Area Access Monitoring and System Networking Transformation under Group Reactor Operation Mode" introduced the status of the existing nuclear power plant control area access monitoring system in the Qinshan area and the improvement of network hardware configuration. The article gives the A three-layer structure of nuclear power plant control area access monitoring system, that is, server-system workstation-hardware, this method will cause complex interface problems due to different equipment at the hardware layer. It is very difficult to uniformly manage and control the dosage of each unit

[0021] The personal surface radiation pollution monitoring of traditional nuclear power plants is an on-site independent operation mode, and the monitoring data is not uploaded and saved. This problem also exists in the system described in the above article
