Fire early detection and alarm system and method

Abstract

The present invention provides a fire early detection and alarm system and method, adopting a plurality of actively aspirating smoke detectors for air sampling to obtain the smoke concentration of protected parts, and adopting a plurality of temperature detectors for temperature detection to obtain the temperature of the protected parts Temperature value, using multiple CO detectors for CO detection to obtain the CO value of the protected part; using the alarm expansion card to receive the smoke concentration, using the loop card to receive the temperature value and CO value, and sending the smoke concentration, temperature value and CO value to the main unit CPU, the main CPU judges the fire alarm level and displays the judgment result. Improve the response time of electrical smoldering fires that are not easy to be detected early in the ship's airtight cabin, integrate the characteristic quantity CO of the combustion products of smoldering electrical fires, and fuse and judge various detector parameters through fuzzy neural networks and genetic algorithms to achieve Early fire alarm function, while improving the ability to resist false alarms.

Description

technical field [0001] The invention relates to an automatic fire alarm technology of a marine fire-fighting system, in particular to an early fire detection and alarm system and method. Background technique [0002] The front-end detection of fire detection and alarm in my country's marine fire-fighting system mainly uses point-type smoke-temperature composite detectors and differential constant temperature detectors, and core boards such as alarm controller main boards, loop cards, and display cards mainly use imported marine products. Because most of the cabins in the ship are closed, the electromechanical equipment is dense, there are many people, and the internal passages are narrow, it takes a long time to sail on the water, and it is difficult to rescue after a fire. Only using point-type passive smoke and temperature detection methods will cause long detection and alarm response time , the problem of weak anti-false alarm ability has hidden dangers to ensure the fire...

Problems solved by technology

Because most of the cabins in the ship are closed, the electromechanical equipment is dense, there are many people, and the internal passages are narrow, it takes a long time to sail on the water, and it is difficult to rescue after a fire. Only using point-type passive smoke and temperature detection methods will cause long detection and alarm response time , the problem of weak anti-false alarm ability has hidden dangers to ensure the fire safety of ships

At the same time, the use of imported products is not conducive to mastering the underlying communication protocols and core technologies. Once production is stopped or trade disputes occur, there are also great hidden dangers for the supply guarantee of subsequent products.
