Automatic alarm device for preventing suffocation of children stranded in the car

Abstract

The invention provides an automatic warning device for preventing children retained in a vehicle from suffocating. A power signal of the warning device is connected with a single-chip microcomputer system, a signal detection part is connected with the single-chip microcomputer system through a driving circuit, a wireless communication module is connected with the single-chip microcomputer system through the driving circuit, and a warning processing part is connected with the single-chip microcomputer system through the driving circuit. When the power signal acquires the information indicating that a certain index has threat, the single-chip microcomputer system is commanded to be powered on to work so as to control the signal detection part to be in a working state; and if a signal of motion of a human body is detected by the signal detection part, the single-chip microcomputer system controls the wireless communication module to notify a vehicle owner, and the single-chip microcomputer system controls the warning processing part to enable a vehicle air conditioner to work so as to give a vehicle anti-theft alarm for warning the vehicle owner and asking for help, thereby gaining time for rescue and further effectively preventing children or pets from being locked in the vehicle and suffocating.

Description

technical field [0001] The invention relates to an automatic alarm device for preventing children or pets from suffocating in a vehicle, which is used for warning the vehicle owner and passers-by for help. Background technique [0002] With the improvement of the quality of life, cars have gradually entered the family, and while providing convenience for the family, many problems have also been exposed. For example, in recent years, the tragedy of children or pets being locked in a car has happened more than once in China. When a child or pet is locked in the car, the body temperature of the child or pet will rise rapidly, and the water in the body will also be lost quickly. The closed and narrow space in the car may also easily cause the child to suffer from hypoxia, which may lead to suffocation in severe cases. Preschoolers, who are far less cognitively capable than adults, are likely to have difficulty flipping a switch or pulling a latch to open a car door, and it's ev...

Problems solved by technology

[0003] Although the Chinese patent CN102982650A discloses a device for detecting whether there are people in the car based on an infrared module when the temperature of the car is too high, it is confirmed whether there is a person by distinguishing the principle that people in the car absorb more infrared rays than other objects due to their higher temperature, but In the actual situation, when the temperature inside the car is not high, the stranded children also face suffocation or carbon monoxide poisoning. When the temperature of the car is high, the temperature of the seat and other objects is much higher than that of the human body, and the infrared detection method is not accurate.
