Carbon monoxide poisoning preventive control system for idling automobile

Abstract

The invention discloses a carbon monoxide poisoning preventive control system for an idling automobile, which comprises a carbon monoxide concentration detection unit, an interior personnel infrared detection unit, a signal processing unit, a first relay, a second relay, a third relay, a fourth relay, an alarm lamp, a buzzer, an automobile horn switch, a window ascending button, a window descending button and an automobile ignition switch. The carbon monoxide concentration detection unit and the interior personnel infrared detection unit are connected with the signal processing unit through wires, and the signal processing unit is connected with the alarm lamp and the buzzer through wires and further connected with a signal source port of each of the first relay, the second relay, the third relay and the fourth relay through a wire. Two wiring ports of a normally-open switch of each of the first relay, the second relay, the third relay and the fourth relay are in parallel connection with the automobile horn switch, the window ascending button and the window descending button through wires, and the two wiring ports of the normally-open switch of the fourth relay are serially connected with the automobile ignition switch through a wire.

Description

technical field [0001] The invention belongs to the technical field of automobile accessories, and relates to a control system for preventing carbon monoxide poisoning in automobiles. More specifically, the invention relates to an automobile idling carbon monoxide poisoning prevention and control system. Background technique [0002] Carbon monoxide is a common poisonous gas. When the carbon monoxide content in the car exceeds 50ppm, the occupants will experience dizziness, vomiting, and even coma. High concentrations of carbon monoxide can cause death within minutes. When the car is running at idle speed, the engine produces the maximum amount of carbon monoxide due to incomplete combustion of fuel, and it is easy to enter the car through air-conditioning pipes, etc., so that the content of carbon monoxide in the car increases sharply, and it is easy to cause carbon monoxide poisoning of the occupants. This type of accident generally occurs when the vehicle is idling and th...

AI Technical Summary

Problems solved by technology

[0005] 1. Cannot automatically take corresponding measures to reduce the carbon monoxide concentration in the car

For some occupants who are resting and sleeping on the idling car, it is likely to cause carbon monoxide poisoning because they cannot hear the warning of the alarm.

[0006] 2. It cannot automatically send a distress signal to passers-by, so that the occupants in the car lose the best rescue time

[0008] 1) Failure to consider the different impacts of different concentrations of carbon monoxide on the human body, failure to do a detailed and comprehensive analysis and consideration, that is, not to take different measures for different concentrations of carbon monoxide, which may cause occupants to be poisoned by low concentration of carbon monoxide

[0009] 2) It cannot automatically send a distress signal to passers-by, so that the occupants in the car lose the best rescue time

[0010] 3) Due to the need to install an intake valve, the changes to the car are relatively large and affect the performance of the car itself

[0011] 4) Measures are taken without considering whether there are passengers in the car, which lacks safety and is inhumane

[0012] 5) Since only the intake valve is used to reduce the concentration of carbon monoxide in the car, the generation of carbon monoxide has not been fundamentally eliminated.
