Embodiment 1

[0071] Please refer to figure 1 , the embodiment of the present application provides a visual image fire alarm system for nuclear power plants, including: a visual fire detection module 1, a visual fire alarm monitor 2 and a fire safety processing device 3 connected in sequence;

[0072] The visual fire detection module 1 is used to monitor and obtain fire alarm information and image information based on on-site fire conditions;

[0073] A visual fire alarm monitor 2, configured to detect the authenticity of a fire on the spot based on the fire alarm information and the image information, and send fire control to the fire safety processing device 3 when the authenticity satisfies a preset condition Signal;

[0074]The fire safety processing device 3 is used for performing safety alarm, safety isolation and fire extinguishing based on the fire control signal.

[0075] Specifically, the visual fire detection module 1 is usually arranged on-site for fire monitoring, and on the ...

Embodiment 2

[0115] Based on the same invention concept, please refer to Figure 5 , the embodiment of the present application also provides a nuclear power plant visual image fire alarm method, which is applied to the nuclear power plant visual image fire alarm system as described in Embodiment 1. The fire alarm system includes: sequentially connected visual fire detection modules 1, Visual fire alarm monitor 2 and fire safety processing equipment 3; the fire alarm method includes steps:

[0116] S1. Obtain fire alarm information and image information through the monitoring of the visual fire detection module 1 and based on the on-site fire situation;

[0117] S2. Using the visual fire alarm monitor 2 to detect the authenticity of the on-site fire based on the fire alarm information and the image information, and when the authenticity satisfies a preset condition, send a message to the fire safety processing device 3 fire control signal;

[0118] S3. Using the fire safety processing dev...

Abstract

The invention discloses a nuclear power station visualization image fire-fighting alarm system and method, and solves the problems in the prior art that a fire-fighting alarm system cannot timely reflect real conditions in an alarm zone, and false alarm or fail alarm can easily happen, and reliability is low; the nuclear power station visualization image fire-fighting alarm system comprises the following elements: a visualization fire hazard detection module (1) used for monitoring field fire hazard conditions and obtaining fire alarm information and image information according to the field fire hazard conditions; a visualization fire hazard alarm monitor (2) used for detecting field fire hazard validity according to the fire alarm information and image information, and sending a fire-fighting control signal to a fire hazard safety processing device (3) when the validity satisfies a preset condition; the fire hazard safety processing device (3) used for carrying out safety alarm, safety isolation and fire extinguishing according to the fire-fighting control signal. The nuclear power station visualization image fire-fighting alarm system and method realize alarm system visualization, can reduce false alarm and fail alarm, thus improving fire-fighting alarm system stability and reliability.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant fire alarm technology, in particular to a nuclear power plant visualized image fire alarm system and method. Background technique [0002] In the existing fire extinguishing systems of thermal power plants, nuclear power plants, factories, warehouses, and civil buildings, fire alarm systems are required. Fire alarm systems generally consist of temperature detectors, smoke detectors, alarm control panels, and sound and light alarms. and other equipment. During the application of the system, heat detectors and smoke detectors can detect fires, but they cannot reflect the actual situation of the alarm area (such as on-site pictures) in a timely manner, and need to be confirmed manually at the scene, so that when a fire actually occurs, it cannot Fire control is carried out at the first time, and when no fire occurs, human resources are wasted to go to the scene for confirmation. [0003...
