Embodiment 1

[0049] see figure 1 , is a flow chart of the automobile thermal suffocation alarm method provided in the first embodiment of the present invention, comprising steps:

[0050] Step S10, when it is judged that the current vehicle is in the state of being turned off and the doors are in the locked state, turn on the infrared sensor installed in the current vehicle;

[0051] Wherein, when it is determined that the engine of the current vehicle is in a shutdown state, the vehicle speed is 0 km / h, the circuit in the vehicle is powered off, and the doors and windows are closed, then it is determined that the current vehicle is in a stationary and unstarted state, that is, the flameout state, Preferably, in this embodiment, the infrared sensor is arranged on the inner wall of the A-pillar of the current automobile;

[0052] Specifically, in this step, the infrared sensors on both sides of the car and in the trunk are used to detect first, to preliminarily determine whether there are ...

Embodiment 2

[0064] see Figure 4 , is a flow chart of the automobile thermal suffocation alarm method provided in the second embodiment of the present invention, including steps:

[0065] Step S11, when it is judged that the current vehicle is in the state of being turned off and the door is in the locked state, turn on the infrared sensor installed in the current vehicle;

[0066] Step S21, when it is determined that the infrared sensor detects vital signs in the current vehicle, turn on the carbon dioxide concentration sensor installed in the current vehicle;

[0067] Step S31, judging whether the increase of the detection value is greater than the increase threshold within the first preset time;

[0068] Among them, when there are three people in the car and the ventilation system is in internal circulation, the carbon dioxide content in the car can rise by 2500ppm within 15 minutes. In order to measure the specific data of the change of carbon dioxide content in the closed car, a lo...

Embodiment 3

[0084] see Figure 5 , is a schematic structural diagram of a car thermal suffocation alarm system 100 provided in the third embodiment of the present invention, including: an infrared sensing module 10, an alarm judgment module 11 and a suffocation prompt module 12, wherein:

[0085] The infrared sensing module 10 is used for turning on the infrared sensor arranged in the current vehicle when it is judged that the current vehicle is in the state of ignition off and the doors are in the locked state.

[0086] An alarm judging module 11, configured to turn on a carbon dioxide concentration sensor located in the current vehicle when it is judged that the infrared sensor detects vital signs in the current vehicle; judge that the detection value of the carbon dioxide concentration sensor meets the alarm requirement. condition;

[0087] Preferably, the alarm judging module 11 is also used for: judging whether the increase of the detection value is greater than the increment thresh...

Abstract

The invention provides an alarm method and system for thermal choking of an automobile. The method comprises the steps that when it is judged that a current vehicle is in a flameout state, and a vehicle door is in a locked state, an infrared sensor in the current vehicle is started; when it is judged that the infrared sensor detects vital signs existing in the current vehicle, a carbon dioxide concentration sensor in the current vehicle is started; whether or not a detection value of the carbon dioxide concentration sensor meets the alarm condition is judged; when it is judged that the detection value meets the alarm condition, a current temperature in the current vehicle is acquired in real time; when it is judged that the current temperature is larger than a temperature threshold value,a choking prompt alarm is given out. According to the method, based on detection of the infrared sensor, the carbon dioxide concentration sensor and the temperature sensor, the phenomenon of low alarmaccuracy caused by adoption of pressure detection is prevented.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile thermal suffocation alarm method and system. Background technique [0002] At present, automobiles have developed rapidly around the world. According to data reports, in the first half of 2018, China's newly registered motor vehicles reached 16.36 million, higher than the 15.94 million registered in the same period last year. The number of new energy vehicles has reached 1.99 million, and the number of private cars has reached 180 million. Since 2018, the number of vehicles has increased by an average of 1.66 million per month, maintaining a sustained and rapid growth. In addition to bringing great convenience to people in the development of automobiles, it also brings many potential safety hazards. Among them, due to the negligence of parents (children), it is not uncommon for children or the elderly to be locked in the car and endanger them. According to the...
