Intelligent vehicle gas safety control device and control method

Abstract

The invention provides an intelligent vehicle gas safety control device and control method for 24-hour real-time car gas safety monitoring, gas leakage alarming and intelligent malfunction processing. According to the technical scheme, the intelligent vehicle gas safety control device consists of a gas concentration sensor module, a vehicle gas safety control module, a car electronic control unit gas safety monitoring and processing module and wiring harnesses for connecting the gas concentration sensor module, the vehicle gas safety control module and the car electronic control unit gas safety monitoring and processing module. By adopting the control device and the control method, the gas safety of a car can be monitored in real time all weather according to different concentration of the gas leakage, the gas leakage alarming and intelligent malfunction processing can be carried out in different areas and different stages, people inside the car can be reminded of checking the gas leakage by virtue of alarming and also can be reminded of taking effective measures to guarantee the gas safety, and safety accidents caused by the gas leakage can be effectively avoided.

Description

technical field [0001] The invention relates to an intelligent control system, in particular to a vehicle gas safety intelligent control device and a control method. Background technique [0002] As a clean energy, natural gas is mainly composed of alkanes, of which methane accounts for the vast majority, and there are a small amount of ethane, propane and butane, which are mainly used correctly, and natural gas is relatively safe. With the continuous development and maturity of natural gas technology for vehicles, and its advantages of high unit calorific value, low exhaust pollution, reliable supply, and low price, natural gas has been more and more widely used in automobiles. As vehicle fuel, there are two types of natural gas, compressed natural gas (CNG) and liquefied natural gas (LNG). Because natural gas is lighter than air and easy to disperse, if natural gas leaks and accumulates to a certain concentration, there is a danger of explosion. [0003] In recent years,...

AI Technical Summary

Problems solved by technology

[0008] 3. The power consumption of the product is relatively large, and the monitoring will be stopped immediately after the vehicle stops, otherwise it will cause the failure of the car to start due to the loss of battery power;

[0009] 4. In addition to the alarm, some systems also integrate a solenoid valve to control and cut off the gas source, especially when encountering a single-fuel vehicle, the function of cutting off the gas source cannot be realized;

[0010] 5. If the leakage concentration detection sensor fails, there is no prompt, and the safety of gas use cannot be guaranteed
