Automatic early-warning window-lowering device for preventing asphyxia of human bodies in vehicle

Abstract

The invention provides an automatic early-warning window-lowering device for preventing asphyxia of human bodies in a vehicle. The automatic early-warning window-lowering device comprises a start button, wherein a control module controls a timer module for timing when the start button is pressed and the timer module simultaneously starts human body sensing modules while starting timing; during thetiming process of the timer module, the human body sensing modules sense the presence of human vital signs and transmits feedback signals to the control module; the control module controls a motor controller according to the feedback signals of the human body sensing modules; and a stepping motor controls a car window lifting and lowering device according to commands from the motor controller soas to control the opening and closing of car windows. The automatic early-warning window-lowering device for preventing the asphyxia of the human bodies in the vehicle determines the presence of the human vital signs in the vehicle during a preset period of time by virtue of the sensing of sensors when the vehicle stops running, and further controls the opening and closing, the opening size and the opening speed of the car windows by virtue of the stepping motor, so as to solve the problems that the human bodies are trapped in the vehicle or the car windows are mistakenly opened.

Description

technical field [0001] The invention relates to station equipment, in particular to an automatic early warning window lowering device for preventing human body suffocation in the train. Background technique [0002] Along with the popularization of vehicles, vehicles have become a means of transportation for people to travel, and it is common to forget to open windows for ventilation when vehicles stop moving. Under airtight conditions, the air in the car is circulated internally through the air conditioner and cannot be renewed. Especially under high temperature and high heat conditions, toxic and harmful exhaust gases such as carbon monoxide are more likely to be produced in the car. , Severe cases even suffocate and die. Contents of the invention [0003] In order to solve the disadvantages of the above-mentioned prior art, the object of the present invention is to provide an automatic early warning window lowering device for preventing human body suffocation in the ve...
