Portable air quality monitoring method and a portable air quality monitoring system

Abstract

The invention relates to the field of environmental protection and particularly relates to a portable air quality monitoring method and a portable air quality monitoring system. The method comprises the following steps: acquiring, sending, receiving and uploading air quality information; returning accurate information; and carrying out visualized display. The system comprises a portable terminal module, an intelligent cell phone application module and a cloud background module. According to the portable air quality monitoring method and the portable air quality monitoring system provided by the invention, terminal equipment with low price and small volume is used so that the real-time monitoring of the air quality information is finished; and meanwhile, the monitoring precision is high.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a portable air quality monitoring method and system. Background technique [0002] Nowadays, ambient air quality has gradually become a new topic in people's lives, and the impact of air quality on health has been paid more and more attention by the public. Obtaining air quality information around you anytime, anywhere has become a new demand. At present, there are mainly several ways to monitor real-time air quality, such as obtaining rough air quality readings through the nearest air quality collection station, and obtaining air quality data by purchasing aerosol measuring instruments such as DustTrack and Dylos. These methods generally have the following problems: the cost is high, the cost of DustTrack, Dylos, ThermoPDR series sensors ranges from several thousand dollars to several hundred dollars respectively, and the air quality collection station is more than one hu...

Problems solved by technology

These methods generally have the following problems: the cost is high, the cost of DustTrack, Dylos, ThermoPDR series sensors ranges from several thousand dollars to several hundred dollars respectively, and the air quality collection station is more than one hundred thousand dollars. The probability of purchase is very low; it is not suitable for carrying, as far as the current air detection systems are concerned, they are relatively bulky and not suitable for carrying; the cheap sensors are not accurate enough, and the air quality sensors (particulate matter sensors) in the market currently cost less than 1,000 yuan The accuracy is very low, and uncalibrated cheap dust sensors are commonly used, and fixed calibration curves. Due to the limited detection range, the reading is far from the actual value in many cases.

Compared with professional products such as Dust-Track or Dylos, micro-dust sensors have obvious disadvantages in terms of detection sensitivity, accuracy, consistency, etc.
