Embodiment Construction

[0023] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] As mentioned above, due to the existence of regional or seasonality, the measurement system has systematic deviations, which affects the accuracy of the detection results. Therefore, the inventors of the present invention propose a management system for air particle detectors, so that the local meteorological department can The PM2.5 value calibrates the air particle detector to improve the accuracy of the detector, so that the local ...

Abstract

The invention discloses a calibration method and a management system of an air particulate matter detector. The calibration method comprises the following steps: installing an air particulate matter detector for calibration near a monitoring station of a third-party authority mechanism; acquiring air particulate matter measured data obtained through detection of the air particulate matter detector for calibration; acquiring air particulate matter monitoring data released by the third-party authority mechanism; obtaining a calibration model based on the air particulate matter measured data and the air particulate matter monitoring data; sending the calibration model to a detector client side, thus calibrating an air particulate matter detector associated with the detector client side, wherein the air particulate matter detector for calibration and the air particulate matter detector associated with the detector client side are used for detecting air particulate matter data based on the same principle. In such a way, the air particulate matter detector related to the detector client side can be calibrated through the calibration model, and the accuracy of the air particulate matter detector is increased.

Description

technical field [0001] The invention relates to the field of air quality monitoring, in particular to a calibration method and management system for an air particle detector. Background technique [0002] In recent years, with the rapid industrialization and the explosive growth of the number of motor vehicles, air pollution has become increasingly serious, especially the increase in the concentration of fine particulate matter (particles with a diameter equal to or less than 2.5 microns, also known as PM2.5), which seriously threatens people's health. health and everyday life. [0003] National standard PM2.5 value definition is μg / m 3 , what is required to be measured is mass (weight). Currently commonly used methods for detecting particle concentration include standard weighing method and laser PM2.5 detection method. [0004] The standard weighing method generally uses appropriate devices to filter out PM2.5 particles, measure the mass of particulate matter, and calcu...
