Vehicle system for detecting oxygen, carbon monoxide and carbon dioxide

Abstract

The invention discloses a vehicle system for detecting oxygen, carbon monoxide and carbon dioxide. The system comprises an oxygen sensor, a carbon monoxide sensor, a carbon dioxide sensor, a signal amplification circuit module, a filtering circuit module, a controller module, a warning module and a display module, wherein weak signals detected by the oxygen sensor, the carbon monoxide sensor and the carbon dioxide sensor are input into the controller module after being amplified by the signal amplification circuit module and filtered by the filtering circuit module; and the controller module is synchronously connected with the warning module and the display module. The system can detect the concentrations of oxygen, carbon monoxide and carbon dioxide in a vehicle in real time; and once the concentrations in the vehicle are not in a normal concentration range, an alarm is immediately given to prompt persons in the vehicle so as to effectively prevent the generation of death with asphyxia in the closed vehicle.

Description

technical field [0001] The invention relates to a system for detecting the concentration of oxygen, carbon dioxide and carbon dioxide in automobiles. [0002] Background technique [0003] Now people's living standards are getting higher and higher, and cars have almost become an indispensable means of transportation for people's family life. While people are enjoying the great convenience brought by cars, there have been many cases of suffocation and death in closed compartments in recent years. There are many cases of suffocation deaths in cars almost every year. But many people don't know that sleeping with the air conditioner on in the car may also cause suffocation. [0004] In fact, the car's air conditioner has two modes. One is the internal circulation mode, which saves gasoline. The internal circulation state is to close the airflow channel inside and outside the car. If the fan is not turned on, there will be no airflow circulation. When the fan is turned o...

Problems solved by technology

At present, although there are some products for detecting the gas condition of automobiles, they are mainly concentrated in the field of gas purification, not for the purpose of preventing suffocation of people in closed automobiles. Therefore, a combination of air sensor technology and electronic technology is used to develop a detection automobile The detection system of internal carbon monoxide carbon dioxide and oxygen concentration is very necessary
