Fire detection device and method under nuclear power station extreme environment condition

Abstract

The invention discloses a fire detection device and method under the nuclear power station extreme environment condition. The fire detection device and method are applicable to video processing underthe fireproof region intrinsic special environment of a nuclear power plant, and a fire intelligent recognition model is formed. The fire detection device comprises a table trolley which comprises a display screen for displaying various data; a processing mainframe is in data connection with the display screen, and a software part and multiple driving programs are installed inside the processing mainframe; a power module supplies power to the table trolley; a data interface board is used for wired and wireless data connection between the interior and the exterior of the table trolley; a video,audio an remote wireless alarm device is used for supplying alarm information to an emergency system or other designated interfaces or providing images or short videos as needed; a plurality of radioresistance camera devices are distributed inside the fireproof region, and each radioresistance camera device comprises a support and a pan-tilt arranged on the support; a camera is arranged on the pan-tilt and has the heating function. The fire detection device is high in interference resistance, good in environmental suitability and stable in working performance.

Description

technical field [0001] The invention relates to the field of nuclear power generation, in particular to a fire detection device and detection method suitable for nuclear power plants under extreme environmental conditions. Background technique [0002] Safety is the lifeline of nuclear power plants, and fire is special to the safety of nuclear power plants, and it has uncertain destructive power. It can be said that fire and nuclear accidents may be derived or transformed from each other under severe accident conditions, so it is necessary to In particular, fire detection in extreme environments is given sufficient depth of attention. The current nuclear power plants have the following problems: [0003] 1. In some harsh environment areas of nuclear power plants, traditional fire detectors often produce false alarms, which frequently cause I0 of the unit and affect the normal operation of the unit. A non-contact technical means with strong adaptability to the environment is...

AI Technical Summary

Problems solved by technology

[0003] 1. In some harsh environment areas of nuclear power plants, traditional fire detectors often produce false alarms, which frequently cause I0 of the unit and affect the normal operation of the unit. A non-contact technical means with strong adaptability to the environment is needed to temporarily replace it;

[0004] 2. The fire detection in the overhaul maintenance area and the temporary material storage area lacks effective control means, and there are hidden dangers in fire safety;

[0005] 3. After the traditional fire alarm system is paralyzed due to other factors, some important areas lack temporary fire detection means, posing safety hazards

[0006] 4. Lack of effective tools and means for fire detection in nuclear power plants under extreme conditions such as radiation environment, severe humid environment, high temperature environment, and corrosive environment
