Video monitoring apparatus, system and method for reactor room

Abstract

The invention discloses a video monitoring system for a reactor room, and relates to the field of reactor room monitoring. The system comprises a collection unit arranged in the reactor room, a receiving unit arranged at the outside of the reactor room, an optical fiber array and a display unit, the collection unit comprises a first shell, a first lens arranged on the first shell and a first array substrate arranged in the first shell, the first lens and the first array substrate are arranged in sequence along a light transmission path; the receiving unit comprises a second shell, a second array substrate, a second lens and an image sensor, and the second array substrate, the second lens and the image sensor are arranged in the second shell and are arranged in sequence along the light transmission path; and the optical fiber array is connected with the first array substrate and the second array substrate. The video monitoring system for the reactor room is good in high temperature resistance, and radiance resistance, long in service life and does not need to be frequently changed, thereby saving the manpower and material resources and greatly reducing the cost.

Description

technical field [0001] The invention relates to the field of reactor cabin monitoring, in particular to a video monitoring device, system and method applied to reactor cabins. Background technique [0002] In the reactor compartment of a nuclear-powered ship, many important hydraulic and pneumatic pipelines and hydraulic and pneumatic equipment are often operated. The temperature in the reactor compartment is usually high and has a certain degree of radiation. It is inconvenient for inspection personnel to enter for observation and inspection. Use video monitoring devices to monitor the operating conditions of these pipelines and equipment in real time, so as to grasp the situation in the reactor compartment in real time, and when abnormalities are found, quickly locate the fault and solve the problem quickly, so as to ensure the safety of the reactor compartment. [0003] In the prior art, the video monitoring device includes a signal-connected CCD / CMOS camera and a video r...

Problems solved by technology

[0004] However, the CCD / CMOS camera includes a charge-coupled device CCD or a metal oxide semiconductor CMOS. These components are very sensitive to temperature and radiation, and their high temperature and radiation resistance are poor. However, the temperature in the reactor cabin is high and the radiation is large, so As a result, the CCD / CMOS camera cannot work for a long time in the reactor cabin, and its service life is short, so it needs to be replaced regularly, which is not only troublesome to replace, wasting manpower and material resources, but also high cost
