In-car carbon dioxide concentration monitoring system and control method thereof

Abstract

The invention provides an intra-compartment carbon dioxide concentration monitoring system and a control method thereof. The intra-compartment carbon dioxide concentration monitoring system comprises a test system, a control system and an execution system. The test system monitors the concentration of carbon dioxide in a compartment and whether a vehicle door is locked or not in real time, and when the concentration of the carbon dioxide exceeds the human body health and comfort level standard and the vehicle door is not locked, the control system controls an air conditioner to be adjusted to be in an outer cycle mode, and air in the compartment is exchanged in real time; and when the vehicle door is locked and after the concentration of the carbon dioxide in the compartment is reduced below the standard value through outer cycle air exchange of the air conditioner, the concentration of the carbon dioxide in the compartment can still be increased and exceed the standard value, it is explained that a person remains in a vehicle, and at the moment, a vehicle-mounted alarm device in the execution system is directly turned on to prompt that the person remains in the vehicle. By the adoption of the system and the control method, the quality of air in the compartment can be monitored, physical and psychological health of a driver and passengers is protected, and harm caused by the fact that the person is left in the vehicle can be prevented as well.

Description

technical field [0001] The invention relates to the field of air quality detection, in particular to a carbon dioxide concentration monitoring system in a vehicle compartment and a control method thereof. Background technique [0002] At present, automobiles have become a part of people's daily life. With the advancement and development of automobile technology, the sealing performance of the compartment is getting better and better. Such sealing also hinders the circulation of air inside and outside the compartment, making the compartment The formation of a relatively closed space will lead to an increase in the concentration of carbon dioxide and a decrease in air quality in the compartment, affecting the physical and mental health of the occupants, and even suffocating, threatening life safety. [0003] At present, most of the car air conditioners on the market need human intervention to turn on, and cannot monitor the air quality in the car, nor can it operate according ...

Problems solved by technology

[0002] At present, automobiles have become a part of people's daily life. With the advancement and development of automobile technology, the sealing performance of the compartment is getting better and better. Such sealing also hinders the circulation of air inside and outside the compartment, making the compartment The formation of a relatively closed space will lead to an increase in the concentration of carbon dioxide in the compartment and a decrease in air quality, affecting the physical and mental health of the occupants, and even suffocating, threatening life safety

[0003] At present, most of the car air conditioners on the market need human intervention to turn on, and cannot monitor the air quality in the car, nor can it operate according to the air quality in the car, let alone judge whether there are people (especially children) stranded in the car. , these deficiencies directly affect the comfort and safety of driving

At the same time, the airtight compartment will cause the concentration of carbon dioxide to rise rapidly, causing the drivers to be listless and inattentive, which indirectly leads to frequent traffic accidents.
