Vehicle fuel gas alarm, alarm method and vehicle comprising vehicle fuel gas alarm

Abstract

The invention discloses a vehicle fuel gas alarm and an alarm method of the vehicle fuel gas alarm. The vehicle fuel gas alarm comprises a detector, a power supply control circuit and a processor. The detector is arranged in a vehicle, detects the concentration of hazardous gas in the vehicle through a sensor, and outputs detection data. The power supply control circuit is connected with a vehicle battery and a vehicle key switch and outputs electric signals according to the state of the voltage of the vehicle battery and the state of the vehicle key switch. The processor is connected to the detector and an alarm control circuit, according to the state signals, output by the power supply control circuit, of the vehicle key switch, the processor controls the alarm to be automatically switched on after the vehicle is started and controls the alarm to be automatically switched off within a preset time period after the vehicle is parked, and the processor conducts analysis processing according to the detection data input by the detector and outputs alarm control signals. The invention further discloses the vehicle comprising the vehicle fuel gas alarm.

Description

technical field [0001] The invention relates to a gas alarm, in particular to a gas alarm for a vehicle, an alarm method thereof, and an automobile using the gas alarm. Background technique [0002] The prevention and control of air pollution is a problem faced by all countries in the world. With the continuous growth of automobiles and the oil crisis, many clean energy or new energy vehicles have been developed, such as using CNG (compressed natural gas), LNG (liquefied natural gas) , LPG (liquefied gas) gas vehicles, or fuel cell vehicles that generate hydrogen when in use. These cars may leak gas during use. As a safety first requirement, many cases also show that it is very necessary to install a gas leak alarm. [0003] From some existing cases, it is found that in many cases, gas accumulation occurs after parking, and an accident occurs when the car is started the next day. Therefore, in order to more reliably protect the safety of the car and its drivers, it is hope...
