Gas exhaust state monitoring system for vehicle air conditioner

Abstract

The invention provides a gas exhaust state monitoring system for a vehicle air conditioner, wherein a vehicle control device is used for judging the stop of driving of a vehicle according to a vehicle driving speed value transferred by a vehicle speed detection device and further enabling a gas concentration detection device to enter a start state according to a user instruction under the situation that an air conditioning device of the vehicle is opened so as to detect the concentration of carbon oxide (CO) in the vehicle and transfer the detected concentration value of the CO to the vehicle control device; and the vehicle control device starts a warning information transmitting device when the concentration value of CO, which is received from the gas concentration detection device, exceeds a preset concentration threshold value so as to enable the warning information transmitting device to emit warning information and send reminding information to a wireless user terminal in a wireless communication way. The invention provides the gas exhaust state monitoring system for the vehicle air conditioner, which can prevent or reduce the safety accidents caused by the opened air conditioner when people have the rest or sleep in the vehicle after parking of the vehicle.

Description

technical field [0001] The invention relates to the field of automobile monitoring, and more specifically, the invention relates to a state monitoring system for exhaust gas from an automobile air conditioner. Background technique [0002] The use safety of a car not only includes the driving safety of the car during driving, but also includes the safety of the car after the car stops running. [0003] Specifically, it is still possible to cause safety hazards after the car stops moving. For example, if the user turns on the air conditioner to rest or sleep in the car after parking in hot summer, or if the user closes the window and turns on the heating to rest or sleep after parking in winter, the air inside the car cannot be convected, causing air turbidity; and , in this case, if the car air-conditioning filter is not cleaned in time, the bacteria and fungi on the car air-conditioning filter may enter the car, the concentration of harmful gases such as carbon monoxide wi...

[0003] Specifically, after the car is stopped, it is still possible to pose a safety hazard

For example, if the user turns on the air conditioner to rest or sleep in the car after parking in hot summer, or if the user closes the window and turns on the heating to rest or sleep after parking in winter, the air inside the car cannot be convected, causing air turbidity; and , in this case, if the car air-conditioning filter is not cleaned in time, the bacteria and fungi on the car air-conditioning filter may enter the car, the concentration of harmful gases such as carbon monoxide will increase, and the density of negative ions that are beneficial to people will decrease. , and if the carbon monoxide emitted by the engine leaks into the car, it will gradually accumulate and its concentration will increase, resulting in poisoning and even death
