Abstract

The invention relates to the technical field of nuclear power station closed circuit television monitoring systems, and specifically discloses an improved irradiation-resistant closed circuit television monitoring system. The system comprises a display, a video matrix, a plurality of cameras, a switching follower and a relay control box, wherein the video matrix is connected with the relay control box through the switching follower; the relay control box is connected with respective independent power supplies of the plurality of cameras respectively; and the plurality of cameras are connected with the video matrix in order that video signals transmitted by the cameras are displayed on the display which is connected with the video matrix through the video matrix. According to the system, independent power supply control is implemented on irradiation-resistant cameras, so that the functions of conventional cameras are not influenced while the irradiation-resistant cameras are effectively protected. Through adoption of the system, the service lives of the irradiation-resistant cameras can be prolonged to two refueling cycles or more; subsequent investments of a user are reduced; investment benefits are increased; and the later-stage maintenance workload is lowered.

Description

technical field [0001] The invention belongs to the technical field of closed-circuit television monitoring systems of nuclear power plants, and in particular relates to an improved radiation-resistant closed-circuit television monitoring system. Background technique [0002] Since my country independently built the first nuclear power plant——Qinshan Nuclear Power Plant, the reactor types of power plants invested and built in my country mainly include: CNP300, CNP650, CRP1000, M310 plus improvement, EPR, AP1000, and Russia’s AES-91, Canada’s CANDU6, etc. [0003] Each of the above stack shapes has its own unique design, and there are certain differences in plant structure, main equipment and auxiliary equipment, but basically they can be divided into various areas in each power station according to different safety requirements and risk levels. It is difficult for staff to enter these high-risk or controlled areas during reactor operation, so an electronic video image acquis...
