Abstract

The invention belongs to the technical field of gas detection, and discloses an air concentration monitoring system and method and an air purifier, the air concentration monitoring system comprises a first detection module, a second detection module and a signal processing module, the first detection module performs target gas detection on a to-be-detected air sample, the to-be-detected air sample is converted into a target gas voltage signal and the target gas voltage signal is output to a signal processing module; the second detection module performs gas detection on the to-be-detected air sample, converts the to-be-detected air sample into a gas voltage signal and outputs the gas voltage signal to the signal processing module; and the signal processing module determines a gas detection difference value according to the target gas voltage signal and the gas voltage signal, and determines a concentration value of the target gas according to the gas detection difference value and a preset gas concentration algorithm. According to the invention, one detection module is used as a reference, the other detection module is used for measurement, and a low-cost scheme, i.e., two cheap detection modules, is used for replacing a high-cost scheme, i.e., a special sensor, so that the measurement cost is reduced.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to an air concentration monitoring system, method and air purifier. Background technique [0002] In recent years, with the rapid development of social economy and the improvement of industrialization and urbanization, the problem of organic pollution in ambient air has become more and more serious. At present, the gas sensors on the market are independently measuring a certain substance or a certain gas. The gas sensors on the market are all special sensors such as formaldehyde sensors, carbon monoxide sensors, temperature and humidity sensors, carbon monoxide sensors, and so on. Moreover, the cost of formaldehyde sensors and carbon monoxide sensors on the market has been high due to reasons such as technology and manufacturing process, and the cost is usually 5-10 times that of ordinary sensors. For example, air purifiers on the market are equipped with formaldehyde sensors...
