Problems solved by technology

There are also some car life-saving systems for children that use temperature detection to achieve life-saving. There are many unrealistic reasons for this kind of life-saving. Harsh, it is difficult to trigger if children are really locked in the car, and it is affected by the temperature in different regions

Embodiment 1

[0029] The child is locked in the car. After the car is turned off and the door is locked, the central controller drives the carbon dioxide sensor to detect the carbon dioxide concentration in the car. The first detection of carbon dioxide concentration is 380ppm, and the time interval of each carbon dioxide concentration is set to 60s. The running time is 1h, that is, within 1h after the car is turned off and the door is locked, the carbon dioxide concentration sensor collects the concentration of the car interior space 60 times, and at the same time, it is set that the difference in carbon dioxide concentration between adjacent ones shall not exceed 40ppm, and every three times The difference in carbon dioxide concentration between neighbors should not exceed 60ppm. When children are locked in the car, the carbon dioxide concentration in the space inside the car will gradually increase. At the same time, due to the small amount of carbon dioxide exhaled by children, the set co...

Embodiment example 2

[0033] On the basis of implementation case 1, the oxygen sensor is used instead of the carbon dioxide sensor to judge whether there are animals or children in the car that need to breathe by collecting the oxygen status in the car.

[0034]Obtaining data information on the car through the signal terminal in the car can confirm that there are no children in the car. The guardian does not need to rush to the scene to shut down the running ambulance system on the car, and directly sends the command to turn off the ambulance system through the mobile terminal. After the device receives the command to stop operation, it will automatically shut down the ambulance system.

Abstract

An intelligent rescue system capable of detecting the carbon dioxide concentration in a car comprises a central controller, a cloud side, a guardian side and a car alarm side and further comprises a carbon dioxide sensor. The carbon dioxide sensor is connected with the central controller; when the car is turned off and a car door is closed, the central controller drives the carbon dioxide sensor to collect the carbon dioxide concentration and starts the carbon dioxide sensor again at preset time to make the carbon dioxide sensor collect the carbon dioxide concentration. The central controller is connected with a car door locking circuit and an in-car signal side and compares signals transmitted by the carbon dioxide sensor; when the difference value of the carbon dioxide concentration reaches a preset range value, the central controller starts the car alarm side and the in-car signal side and transmits in-car data collected by the in-car signal side to the cloud side. The intelligent rescue system is used for dealing with the situation that a child is locked in the car; because the space in the car is an airtight environment, whether the child exists in the car or not can be judged according to the carbon dioxide concentration or oxygen concentration in the car, and then the car alarm side or the guardian side is triggered to give an alarm.

Description

technical field [0001] The invention relates to an intelligent lifesaving device for children in a car, in particular to an intelligent rescue system for detecting carbon dioxide concentration in a car. Background technique [0002] With the progress of society and the improvement of people's living standards, more and more families start to own cars and use them for transportation. Then there is the problem of car safety, especially for children in the family. If you are in a sealed car under your ability, there will be a danger of suffocation before being rescued. It is not uncommon for children to be locked in the car for too long at home and abroad, vomiting, nausea due to lack of oxygen, and more serious suffocation. . [0003] In the prior art, the ambulance system for children locked in the car senses the abnormal situation in the car through vibration. However, because the children are young, they may not be too restless when they are in a dangerous situation. At th...
