In-vehicle trapped person alarming and cooling system and cooling method thereof

Abstract

The invention discloses an in-vehicle trapped person alarming and cooling system and a cooling method thereof. The system is characterized by comprising a central processing unit, a detection device,an alarm device and a cooling device, and the detection device, the alarm device and the cooling device are all arranged in a vehicle and connected with the central processing unit. The detection device comprises a temperature sensor, a pyroelectric sensor and a camera; the temperature sensor is used for converting vehicular internal temperature into electric signals and transmitting the electricsignals to the central processing unit; the pyroelectric sensor is used for detecting in-vehicle infrared rays in specific wavelength after flameout of the vehicle and sending to the central processing unit; the camera is used for acquiring in-vehicle pictures to transmit to the central processing unit; the cooling device comprises a refrigerating module and a heat dissipating module. The system has advantages that after flameout of the vehicle in hot days, emergency vehicle alarming and automatic cooling measures can be taken under the condition that elderly persons and children are trapped in the vehicle so as to buy a great quantity of time for rescuing trapped persons in the vehicle, and safety guarantee is provided.

Description

technical field [0001] The invention relates to an alarm and cooling system for people staying in a vehicle and a cooling method thereof, belonging to the technical field of temperature control safety in a vehicle. Background technique [0002] In recent years, in the hot summer, there have been tragic cases of accidents involving the elderly and children who were stranded in the car. When the car is exposed to high temperature, the temperature inside the car will rise in a short period of time. The elderly and children who are stranded in the car often So life is in danger. The present invention is an intelligent detection and alarm system designed based on this situation, and can take emergency cooling measures when the temperature rises sharply, so as to gain more precious time for the rescue of the elderly and children. [0003] At present, the in-vehicle alarm devices used on the market include carbon dioxide sensors, gravity sensors, infrared sensors, etc. These detec...

AI Technical Summary

Problems solved by technology

[0003] At present, the car alarm devices used on the market include carbon dioxide sensors, gravity sensors, infrared sensors, etc. These detection methods have a high probability of misjudgment and are easily disturbed by the external environment

Moreover, these products often only have an alarm function. When the car owner is far away from the car, although the alarm message has been received, the elderly and children stranded in the car will face life-threatening situations because they cannot be rescued for a long time.
