Gas leakage alarm device for gas car

Abstract

The invention discloses a gas leakage alarm device for a gas car. The alarm device comprises a control host, a solenoid valve and a plurality of gas-sensitive sensors. The gas-sensitive sensors are connected with the control host for sensing the concentration of the natural gas in the environment. The solenoid valve is arranged at the gas outlet pipeline of a gas bottle and connected with the control host through a signal line. After the natural gas concentration exceeds the normal concentration value, the gas-sensitive sensor is used to transmit the sensing signal to the control host, and the control host is used to send a valve turn-off execution signal to the solenoid valve to make the solenoid valve execute the valve turn-off action to close the gas bottle. The control host is provided with a display panel and connected with an undervoltage and overvoltage protection device. The display panel is provided with a reset button, a mute button and alarm indicating lamps corresponding to the gas-sensitive sensors. The undervoltage and overvoltage protection device can be used to perform undervoltage and overvoltage detection on a car storage battery. According to the invention, advantages of fast alarm response speed, good sensitivity and good anti-interference performance can be realized, and an alarm signal can be given when the storage battery is in the undervoltage or overvoltage condition.

Description

technical field [0001] The invention relates to the field of gas leakage alarm equipment, in particular to a gas leakage alarm for gas vehicles with fast alarm response speed, good sensitivity and strong anti-interference. Background technique [0002] As a more and more popular means of transportation, automobiles have made important contributions to the convenience of people's travel. However, most of the automobiles currently use gasoline and other highly polluting fuels. The exhaust gas produced has brought serious pollution to the environment. The role of gas vehicles with green environmental protection and energy saving is also becoming more and more obvious. Gas has inherent advantages such as large storage capacity and low pollution. In the case of limited oil storage, gas has been put into use as a new energy source for automobiles, and it will also increase rapidly. The use of this low-pollution gas as a vehicle energy source can greatly reduce the pollution and ...

Problems solved by technology

However, there is also the problem of gas leakage at the same time. The gas is colorless and odorless, and its leakage is not easy to be discovered.

However, most of the existing gas leakage alarms can only be used in the household environment, or the household alarms are simply refitted. In terms of appearance and installation dimensions, the design concept does not take into account the actual situation of the car. There are defects in the input voltage of the car battery and the anti-vibration of the gas sensor
