Alarm device and detection method for in-vehicle human body detection

Abstract

The invention discloses an alarm device for in-vehicle human body detection, and the device comprises a microprocessor, wherein an infrared sensor is arranged inside a vehicle; the infrared sensor is connected to the microprocessor; a vehicle window sensor which detects whether a vehicle window is closed is disposed on the vehicle window; a vehicle door sensor used to detect whether a vehicle door is closed is disposed on the vehicle door; the vehicle window sensor and the vehicle door sensor are connected to the microprocessor; the microprocessor is connected to an ignition device and a voice alarm device of the vehicle; and the microprocessor is connected to a vehicle speed detection device and an in-vehicle temperature detection device of the vehicle. The alarm device for the in-vehicle human body detection can remind a driver or a passenger that a person still stays in the vehicle after the driver parks the vehicle, so that a life danger of a child left in the vehicle can be avoided; benefits can be brought to families and the society; personal safety of the driver is enhanced; and pains brought by mistakes made by the driver or the passenger to the families can be avoided. The alarm device for the in-vehicle human body detection can detect an in-vehicle temperature and states of the doors and the windows and provide overtime voice alarming so as to provide timely salvation for in-vehicle passengers.

Description

technical field [0001] The invention relates to automotive electronics, in particular to a detection and alarm device and a detection method for a human body in a vehicle. Background technique [0002] In recent years, the media often reported that due to the negligence of parents or children's playfulness, children were left alone in the car, resulting in long-term high-temperature roasting or suffocation and death. [0003] At present, after the driver stops and leaves the vehicle, there are mainly two dangerous situations: [0004] 1. After the driver stops the vehicle, the engine is turned off, the windows are closed, and the doors are locked. The windows can be raised manually by the driver, or by one-button lifting. Children stay in the car, and adults either forget or go out to do errands. The child sleeps alone in the car. [0005] 2. The driver does not turn off the engine after the vehicle stops, the windows are closed, and the doors are closed. Toddlers stay in...

AI Technical Summary

Problems solved by technology

[0006] The first situation has the following problems: the windows are closed and the door is locked, and the child cannot open it. If it is summer hot weather, the temperature inside the car may rise to 60 or 70 degrees within half an hour, and the air is not circulating. The windows of the car are covered with film, and the outside world is not easy to detect the situation inside the car, which can easily lead to the death of children

[0007] The second situation has the following problems: even if the vehicle does not turn off, the windows are closed and the doors are closed

If the air conditioning system is not turned on to cool down and circulate air, it is easy to cause harmful gases in the car to rise and high temperature, resulting in injury or even death of young children

[0008] Since the existing technology does not detect whether there are people in the car, especially children, when the car is locked, there is a great potential safety hazard in the case of adult negligence.
