Embodiment 1

[0045] see figure 1 , which shows the vehicle-mounted vital body monitoring and alarming method in the first embodiment of the present invention, including steps S11-S15.

[0046] S11. Obtain the power-off command of the vehicle. When it is detected that the vehicle is in a closed state, the millimeter-wave radar is activated to transmit a pulse signal into the vehicle for detection, and the echo signal reflected after the detection of the pulse signal is received to detect whether the echo signal has vital signs. Signal.

[0047] Millimeter-wave radar is used as the main controller for vehicle vital signs monitoring and alarm. Millimeter-wave radar determines that the current vehicle power supply is OFF, the seat belt of the main driver is not fastened, and the windows and sunroofs in the vehicle are closed or the opening position is less than 10%. At this time, the door is locked or unlocked for a long time, but the door is in a tightly closed state. The millimeter-wave rad...

Embodiment 2

[0063] see figure 2 , which shows the vehicle-mounted vital body monitoring and alarming method in the second embodiment of the present invention, including steps S21-S28.

[0064] S21. Obtain the power-off instruction of the vehicle. When it is detected that the vehicle is in a closed state, the millimeter-wave radar is activated to transmit a pulse signal into the vehicle for detection, and the echo signal reflected after the detection of the pulse signal is received to detect whether the echo signal has vital signs. Signal.

[0065] Millimeter-wave radar is used as the main controller for vehicle vital signs monitoring and alarm. Millimeter-wave radar determines that the current vehicle power supply is OFF, the seat belt of the main driver is not fastened, and the windows and sunroofs in the vehicle are closed or the opening position is less than 10%. At this time, the door is locked or unlocked for a long time, but the door is in a tightly closed state. The millimeter-wa...

Embodiment 3

[0109] An embodiment of the present invention provides a vehicle-mounted vital body monitoring and alarm system, please refer to Figure 4 , the vehicle-mounted vital body monitoring and alarm method system in this embodiment is shown, and the system shown includes:

[0110] The detection module is used to obtain the power-off command of the vehicle. When it is detected that the vehicle is in a closed state, it starts the millimeter-wave radar to transmit a pulse signal to the vehicle for detection, and receives the echo signal reflected after the detection of the pulse signal, and detects the Whether there is a vital sign signal in the echo signal;

[0111] a first judgment module, configured to collect multiple detection results every preset period, and determine that there is life within the preset period when the ratio of the detection results of the vital sign signal within the preset period reaches a first preset rate;

[0112] The second judging module is configured to...

Abstract

The invention provides a vehicle-mounted life body monitoring alarm method and system, a storage medium and equipment, and the method comprises the steps: obtaining a vehicle power-off instruction, carrying out the detection according to an echo signal received by a millimeter-wave radar when a vehicle is detected to be in a closed state, collecting a plurality of detection results every preset period, and carrying out the detection according to the detection results. When the ratio of the detection results of the vital sign signals in the preset period reaches a first preset ratio, the detection results in a first time period are continuously collected, the first time period comprises a plurality of preset periods, and whether the ratio of the detection results of the vital sign signals in the first time period reaches the first preset ratio or not is judged; and if yes, determining that life exists in the vehicle, and triggering an alarm mode. According to the vehicle-mounted life body monitoring and alarming method and system, the storage medium and the equipment, periodic and cyclic detection judgment of the first time period is performed on the echo signals received by the millimeter wave radar, and the precision of in-vehicle life detection is improved.

Description

technical field [0001] The present invention relates to the technical field of automotive electronics, in particular to a method, a system, a storage medium and a device for monitoring and alarming an in-vehicle living body. Background technique [0002] In recent years, with the popularity of private cars, it is not uncommon for children to be trapped in cars and cause suffocation accidents, and there are countless cases of pets trapped in cars causing death. Therefore, out of respect for life, in-vehicle life detection technology is valued by more and more companies. [0003] In order to solve this problem, many car companies have launched their own in-vehicle vital signs detection technology. These schemes are roughly divided into several categories: infrared detection schemes, camera detection schemes, and gravity sensing detection schemes. The application of the above technologies is affected by limiting factors such as high temperature weather, light brightness, and ...
