Abstract

The invention discloses an atmospheric pollutant detection device and a data calibration method thereof, and belongs to the field of atmospheric monitoring. The invention provides an air pollutant detection device. The air pollutant detection device comprises an NO2 measurement module, an O3 measurement module, a temperature and humidity measurement module and a microcontroller. The device is provided with a GPRS communication module and a storage module, and the GPRS communication module and the storage module are connected with the microcontroller, thereby achieving the communication and storage functions of monitoring data. The GPRS module is used for uploading data acquired by the monitoring device to the monitoring cloud platform and receiving parameters issued by the monitoring cloud platform; on the other hand, the invention provides a calibration method which comprises the following steps: receiving data uploaded by the pollutant monitoring device and pollutant concentration data of the pollutant monitoring calibration base station, carrying out linear regression to obtain a value of an undetermined coefficient, issuing the undetermined coefficient to the detection device, updating a formula, calculating to obtain the concentration of a target pollutant, and storing the concentration of the target pollutant.

Description

technical field [0001] The invention relates to an air pollutant detection device and a data calibration method thereof, belonging to the technical field of air pollution monitoring. Background technique [0002] Atmospheric environmental monitoring and governance has received widespread attention from people and support from the state. Atmospheric monitoring is the basis of air pollution prevention and control. Traditional optical detection technology and chemical detection are limited by high cost, fixed monitoring sites and low real-time performance. The use of new technologies to realize atmospheric environment monitoring has become a mainstream trend. The application of electrochemical sensors has achieved high precision, low cost, flexible layout, and flexible collection of air pollutant data. However, due to the simple principle of the detection signal of the electrochemical sensor, the sensor itself cannot be calibrated, and the collected data needs to be calibrat...
