Poisoning prevention control system against poisonous gas in vehicle and control method thereof

Abstract

A poisoning prevention control system against poisonous gas in a vehicle comprises a poisonous gas detection unit, a control unit, a first alarm unit and a second alarm unit. The poisonous gas detection unit is used for detecting the concentration of the poisonous gas in the vehicle. The control unit comprises a central processing module and a time control module. The central processing module receives the poisonous gas concentration and simultaneously sends first alarm control signals and first timing signals according to the poisonous gas concentration. The time control module sends first control conversion signals to the central processing module according to the first timing signals so that the central processing module can stop sending the first alarm control signals according to the first control conversion signals and send second alarm control signals. The first alarm unit receives the first alarm control signals and gives an alarm according to the first alarm control signals. The second alarm unit receives the second alarm control signals and gives an alarm according to the second alarm control signals. The invention further relates to a poisoning prevention control method against the poisonous gas in the vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile safety, and in particular to an anti-poisoning control system and a control method for poisonous gas in a vehicle. Background technique [0002] As we all know, the exhaust gas emitted by automobiles contains a relatively high concentration of toxic gases such as carbon monoxide. Carbon monoxide (CO) is colorless and odorless, and is a common toxic gas. The affinity between carbon monoxide and hemoglobin in the body is 200-300 times greater than the affinity between oxygen and hemoglobin. When carbon monoxide in the air reaches a certain concentration, such as 35ppm, it will cause damage to the human body, resulting in hypoxia in the body, which is called carbon monoxide poisoning. Carbon monoxide poisoning can cause dizziness, vomiting, coma, and can even be fatal.

AI Technical Summary

Problems solved by technology

[0003] In hot summer or cold winter, many drivers and occupants often turn on the air conditioner of the car to rest in the car. The maximum value, and it is very easy to enter the car through air-conditioning pipes, etc., so that the carbon monoxide content in the car will increase sharply, resulting in carbon monoxide poisoning of the drivers and passengers in the car

Because this kind of carbon monoxide poisoning accident usually occurs when the car is idling and the driver and passengers are resting, it is difficult for passers-by to find out and give rescue.
