Abstract

The invention relates to the technical field of vehicle fire prevention and discloses a water mist spraying system for preventing a static electricity caused vehicle fire. The system comprises a driving computer. Before a vehicle-mounted diagnosis system of a vehicle detects leakage of a fuel evaporation and emission control system, the driving computer performs judgment according to environmentalhumidity detected by a humidity sensor first. When data fed back by the humidity sensor is in a normal range and it is unnecessary to increase the environmental humidity, the driving computer neithersupplies electricity to a water pump to start the water pump nor supplies electricity to an electromagnetic valve to start a water mist nozzle. When the data fed back by the humidity sensor is not inthe normal range and it is necessary to increase the environmental humidity, the driving computer either supplies electricity to the water pump to start the water pump or supplies electricity to theelectromagnetic valve to start the water mist nozzle to spray an external environment to increase humidity so as to eliminate probable static electricity. The system is novel in design and simple in structure and has the advantage of preventing the static electricity caused fire.

Description

technical field [0001] The invention relates to the technical field of vehicle fire prevention, in particular to a water spray system for preventing vehicle fire caused by static electricity. Background technique [0002] In a dry environment, the static electricity generated when the vehicle is running is not easy to eliminate, and it will accumulate more and more. When the static electricity accumulates to a certain extent, it will discharge and generate electric sparks. If the gasoline vapor of the vehicle leaks out, and there is a If there is a static spark, the vehicle may be ignited. [0003] A possible situation where the gasoline vapor of the vehicle leaks violently is when the on-board diagnostic system performs leak detection on the fuel evaporative emission control system, especially the positive pressure detection system, and the on-board diagnostic system often performs leak detection on the fuel evaporative emission control system. Items that will be carried o...
