Description
Technical Field
The invention relates to the field of monitoring and early warning of harmful gases in a vehicle, in particular to a system and a method for monitoring and early warning of harmful gases in a vehicle in real time.
Background
With the increasing number of the family cars, the problem of the quality of the air in the car becomes more and more a focus of people. Currently, based on the types and main sources of volatile organic compounds in the air in the vehicle and the analysis of the volatilization characteristics of main interior materials in the vehicle, approximately 8 types of harmful gas substances in the vehicle are respectively benzene, toluene, formaldehyde, xylene, ethylbenzene, styrene, acetaldehyde, acrolein and the like, which are collectively called voc (volatile organic compounds), namely volatile organic compounds. According to the standard of the concentration of indoor harmful substances, the standard of the indoor formaldehyde content is less than or equal to 0.1mg/M3, and the concentration of TVOC harmful gas is less than or equal to 0.60 mg/M3. The same health standards should be maintained in the vehicle. Therefore, the measurement of the concentration of harmful gas in the vehicle becomes important.
The domestic research on the problem of air pollution in the vehicle has also achieved remarkable achievement in recent years. For example, chinese patent document CN201810198376.6 provides "a multi-component bluetooth car air purifier and a control method thereof", and the application proposes a multi-component bluetooth car air purifier and a control method thereof, including: a plurality of air outlet air purification subassemblies, a plurality of door window air purification subassemblies and bluetooth host computer. The patent has the disadvantage that only air purification can be carried out through the patent, and the wireless alarm function is not available.

The patent can give out sound and light alarm only when the concentration of formaldehyde and carbon monoxide in the vehicle reaches the value capable of causing human body injury; when no driver or passengers are in the vehicle, the concentration of the toxic gas in the vehicle can be sent to the user in a short message form; the defect is that the user can only send information to give an alarm after the gas concentration exceeds the standard, and the user can not actively inquire the concentration of the harmful gas through a mobile phone outside the automobile.

The current technical difficulty is how to actively inquire the concentration of harmful gas in the vehicle when people want to enter the vehicle but not enter the vehicle.
