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.

Embodiment Construction

[0023] Such as figure 1 As shown, a method for intelligent monitoring and control of oxygen content in a vehicle includes the following working steps:

[0024] (1) Detect whether there are occupants in the vehicle: If it is judged that there are no occupants in the vehicle, the detection is terminated; if occupants are detected in the vehicle, the values ​​of the first alarm threshold and the second alarm threshold are limited according to the number of occupants in the vehicle , go to step (2); the first alarm threshold is greater than the second alarm threshold.

[0025] The first alarm threshold and the second alarm threshold are used to limit the warning value of the oxygen content in the vehicle. When the oxygen content in the car is lower than the value set by the first alarm threshold, it means that the quality of the oxygen content in the car is no longer within the optimal range; when the oxygen content in the car is lower than the second alarm threshold, it means th...

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...
