Intelligent detection and control system for harmful gases in the car
Function introduction
Design background
When the car engine is in working condition, it cannot fully burn the fuel. The part that doesn't burn clean becomes carbon monoxide. Carbon monoxide is a colorless and odorless harmful gas. When the gas reaches a certain concentration, it will affect people's vision, hearing, spatial perception, judgment, fatigue and drowsiness, etc. Seriously affect driving safety. The cause of many car accidents is related to carbon monoxide poisoning.
When a vehicle is stopped, the concentration of carbon monoxide in the vehicle will accumulate and increase in a short period of time, seriously affecting personnel safety. Reports of deaths caused by carbon monoxide poisoning in cars continue to appear in the news media, and people's awareness of air safety in cars has increased to a certain level.
As we all know, the working principle of all air purification systems is to rely on filters for filtration, but the filters can only purify dust and impurities in the car. There is no way to purify harmful gases. Therefore, any form of purification device cannot eliminate the presence of harmful gases. The only way is to dilute it. Once harmful gases exceed the standard, ventilation can only be used to resolve the danger. If the purification system can be promoted to eliminate poisonous gases. That is nonsense and does great harm to people!
2. Product Introduction
This product has won the national patent, patent certificate number "The product is easy to install, does not need to break the stranded wire, is dedicated to special vehicles, does not affect the appearance, and is suitable for all models!
This system is equipped with a three-level safety protection device for people in the car. When the vehicle is started, the system will issue a voice prompt to start the car and please open the windows for ventilation. Note that the self-test of the air safety system during driving starts in 10 minutes,
, and the first-level safety function
When the concentration of harmful gases in the car reaches a certain level, the system will automatically sound a voice alarm to indicate that the air quality in the car exceeds the standard. Please open the windows for ventilation in time. However, Will not lower the windows
, secondary safety function
When harmful gases in the car reach the level, the secondary safety system starts and issues an alarm sound. Please open the windows for ventilation if the air quality in the car exceeds the standard. If the car owner does not wake up or takes no measures, the system will automatically lower the window for a few seconds.
, three-level safety function
If the gas in the car reaches the level within a short period of time. The three-level early warning system is activated, and all windows are lowered at the same time as the alarm.
