Nuclear power plant area security method and system

Abstract

The invention provides a nuclear power plant area security method. The method comprises steps: a drone conducts inspection on the nuclear power plant area, peripheral person and surrounding environment images of the nuclear power plant area are photographed, own position coordinates are also acquired, and the images and the own position coordinates are transmitted to a command center; the commandcenter performs person image comparison, after the person is determined to be an outside person, comparison among the surrounding environment image photographed by the drone, the drone position coordinates, a warning area boundary identification line position and an environment image is carried out, the current intrusion behavior and the previous intrusion record of the outside person are determined, and in preset warning levels and corresponding security strategies, the warning level triggered by the outside person currently is obtained, the corresponding security strategy is started and executed to stop intentional invasion or destruction of the outside person. When the method and the system are executed, on the basis of not increasing manpower input, multi-dimensional, low-blind area and high-efficiency novel security is formed, the nuclear power plant warning efficiency can be effectively enhanced, and the possibility of deliberate intrusion or destruction by persons can be reduced.

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
