A safety protection method and system for a nuclear power plant site

Abstract

The present invention provides a safety protection method for a nuclear power plant area, which includes conducting a patrol inspection of the nuclear power plant area by an unmanned aerial vehicle, taking pictures of peripheral personnel and surrounding environment images of the nuclear power plant area, obtaining its own position coordinates, and transmitting the images and its own position coordinates to the command center; The command center compares the images of personnel, and after determining that they are outsiders, compares the surrounding environment images taken by the UAV and the location coordinates of the UAV with the position of the border identification line of the warning area and the environmental image to determine the current intrusion behavior of the outsiders and their location. Pre-intrusion records, and in the preset alert level and corresponding security strategy, get the alert level currently triggered by outsiders and the corresponding security strategy and start execution to prevent outsiders from deliberately invading or destroying. The implementation of the present invention forms multi-dimensional, low-blind-spot high-efficiency new security without increasing manpower input, which can effectively improve the security efficiency of nuclear power plants and reduce the possibility of intentional intrusion or destruction by personnel.

Description

technical field [0001] The invention relates to the technical field of safety inspection of nuclear power plants, in particular to a safety protection method and system for a nuclear power plant area. Background technique [0002] Since a large amount of radioactive spent fuel and nuclear fuel are stored in commercial nuclear power plant areas, in order to ensure nuclear safety, nuclear power plant areas often adopt multiple security measures to prevent unauthorized personnel from approaching and intruding. The nuclear power plant site can be divided into multiple areas from outside to inside according to different actual functions, including: living area, control area, protection area and critical area. Different areas are divided by invisible fences, visible fences (barbed wire) and buildings, and monitored by guards and necessary control facilities. [0003] Due to the need for cooling, nuclear power plants are often arranged by the sea, and in order to reduce the impact...

AI Technical Summary

Problems solved by technology

In some places, the various areas tend to be relatively close to each other, and if unauthorized personnel approach, the response time is often short

In addition, due to limited manpower and material resources, as well as recording the topographical shelter formed by shelters such as forests and diversion channels, it is often only possible to arrange 1-2 sentry posts on a length of several kilometers, resulting in many blind spots in the field of vision (such as figure 2 and image 3 As shown), it is impossible to achieve relatively complete security, and unauthorized personnel crossing the area occurs from time to time, especially at night, the effectiveness of personnel security and the efficiency of identification are low

Even for nuclear power plant sites located at sea (such as the hull carrying nuclear reactors), although the security range is relatively small, due to the complex humanities and terrain, traditional security methods are prone to loopholes
