In-car air quality monitoring and purification regulating system

Abstract

Provided is an in-car air quality monitoring and purification regulating system. A storage battery and three devices respectively powered by the storage battery are installed in a car. The three devices are a ventilating device, an adsorption and filtering device and a heating device. A temperature and humidity sensor, a formaldehyde sensor, a carbon monoxide sensor, a total volatile organic compound sensor and an inhalable particle sensor which are installed in the car are respectively connected with a system control module, and the system control module comprises a sensor signal processing circuit and a power supply on-off control circuit for the three devices. The system can monitor indexes such as in-car air quality and temperature and humidity in real time and start the three devices according to the index overproof conditions; the indexes can also be uploaded through the wireless network to a mobile by the system control module to be displayed in real time; the mobile phone can send instructions to the system control module according to users' requirements to start or shut down the three devices in real time, and purification adjustment of in-car air is achieved.

Description

technical field [0001] The invention belongs to an air quality monitoring and purification device in an automobile, and in particular relates to an air quality, temperature, and humidity monitoring and air purification temperature and humidity adjustment system in an automobile. Background technique [0002] According to the inspection by the Indoor Air Monitoring Center of the China Interior Decoration Association, if the indoor air quality standard is referred to, 93.5% of the cars have the problem of excessive air pollutants such as formaldehyde in the car, and the air quality inside the new car is the worst. When the car is exposed to the hot sun for more than half an hour, the temperature inside the car will rise to above 65 °C, which will accelerate the release of harmful pollutants such as formaldehyde in the car and seriously endanger the health of drivers and passengers. At the same time, because the temperature inside the car is too high, entering the car is like e...
