Intelligent monitoring and controlling method and device for oxygen content in car

Abstract

An intelligent monitoring and controlling method for oxygen content in a car uses cycle wakeup for operation. The method includes when operation is started, monitoring whether there are passengers in the car or not, and starting to monitor oxygen content in the car if the passengers are detected to be in the car under wakeup condition; alarming by a system to remind the passengers in the car of paying attention to space ventilation in the car when oxygen content in the car is lower than a first alarm threshold value and anoxic risk is possibly caused, and turning on an air conditioner for ventilation simultaneously to improve air condition in the car; and activating an alarm when oxygen content in the car is detected to be further reduced and is close to a second alarm threshold value and the passengers in the car are in danger of life, and unlocking locks of four doors so that people outside can come in to rescue. After operation is finished, the system enters a sleep state to save energy. The invention further discloses a device implementing the method. By the use of the intelligent monitoring and controlling method and device, lives and health of the passengers in the car can be prevented from threatening of insufficient oxygen content.

Description

technical field [0001] The invention belongs to the field of automotive electronics, in particular to the field of vehicle environment monitoring using sensor technology and electronic control technology. Background technique [0002] With the improvement of living standards, cars have gradually become a common tool in people's daily life, and various problems related to vehicles have gradually attracted people's attention. Usually, in order to improve the cooling (heating) efficiency of the vehicle, the doors and windows of the car are closed, so that the air inside and outside the car cannot be convected normally. Closing the windows and doors for a long time will improve the cooling (heating) efficiency of the vehicle and make the occupants more comfortable, but it will also cause serious air pollution in the vehicle. When the situation is serious, it may even cause an accident in which the oxygen content in the car is too low and the occupants in the car die due to insu...

AI Technical Summary

Problems solved by technology

Usually, in order to improve the cooling (heating) efficiency of the vehicle, the doors and windows of the car are closed, so that the air inside and outside the car cannot be convected normally.

Closing the windows and doors for a long time will improve the cooling (heating) efficiency of the vehicle and make the occupants more comfortable, but it will also cause serious air pollution in the vehicle

When the situation is serious, it may even cause an accident where the oxygen content in the car is too low and the occupants in the car die due to insufficient oxygen supply.
