Automatic fire extinguishing system for vehicle

Abstract

An automatic fire extinguishing system for a vehicle comprises a fire extinguishing agent container, a fire disaster probe, a power module and a system central control module, wherein the fire extinguishing agent container, the fire disaster probe, the power module and the system central control module are arranged in the vehicle; the power module provides direct current for work of a system, an outlet of the fire extinguishing agent container is connected with a fire extinguishing pipeline with a fire extinguishing electromagnetic valve, and a fire extinguishing nozzle is formed in the tail end of the fire extinguishing pipeline; the system central control module comprises a processing unit, a vehicle door lock relay drive circuit, a fire extinguishing electromagnetic valve drive circuit, an engine relay drive circuit and an oil tank electromagnetic valve drive circuit; the signal output end of the fire disaster probe is connected with the processing unit, and the signal output end of the processing unit is connected with the vehicle door lock relay drive circuit, the fire extinguishing electromagnetic valve drive circuit, the engine relay drive circuit and the oil tank electromagnetic valve drive circuit; and the fire disaster probe and the fire extinguishing nozzle are arranged in the vehicle, when the warning condition happens, a fire extinguishing agent is sprayed out of the fire extinguishing nozzle, and casualties and property losses brought by the fire disaster can be reduced to the maximum limit.

Description

technical field [0001] The invention belongs to the technical field of vehicle fire extinguishing, and in particular relates to an automatic vehicle fire extinguishing system. Background technique [0002] It is self-evident that the loss of life and property due to the spontaneous combustion and fire of passenger cars, fires in passenger cars not only cause huge economic losses, but also cause huge psychological damage to family members and society (the latest case is Taiwan 2016.7 On .19, the mainland tourist group bus caught fire, killing a total of 26 people including the driver and tour guide, 24 of whom were all tourists from Liaoning, mainland China. After investigation, the main cause of the accident was the short circuit of the old circuit of the vehicle and the fire). [0003] The main causes of fire phenomena such as spontaneous combustion and fire in passenger cars are: [0004] 1. Passenger cars are subject to the aging of the oil circuit and circuit caused by ...

AI Technical Summary

Problems solved by technology

[0004] 1. Passenger cars are subject to the aging of the oil circuit and circuit caused by the long service life, and fatal combustion will occur when the characteristic physical quantities of fire (temperature, smoke, gas, fuel splash and radiant light intensity, etc.) are reached; and it will be accompanied by Rapid fire spread and fuel tank explosion, causing unnecessary loss of life and property;

[0005] 2. Negligence and omissions in the assembly process of passenger cars, as well as defects in the circuit and oil circuit design, are also hidden dangers of fire;

[0006] 3. Improper operation of passenger cars during use can also cause accidental fires;

[0007] 4. When attacked by external combustibles, it will also burn and catch fire
