Embodiment 1

[0035] The sample area in this example is Yixing City, Jiangsu Province. Yixing City is located at 31°07′-31°37′ north latitude and 119°31′-120°03′ east longitude. It is located at the junction of Jiangsu, Anhui and Zhejiang provinces, and is connected to the water surface of Taihu Lake in the east. Yixing City has two national monitoring stations, Yiyuan and Yixing Environmental Protection Bureau. In this example, the data of Yiyuan monitoring station from June 1, 2017 to July 31, 2017 were used as standard data, and the PM2.5, PM10, SO 2 , CO, NO, O 3 A total of 6 air parameters were used for data calibration. Joyee equipment uses 3SP series sensors produced by SPEC Corporation of the United States to measure SO by electrochemical methods 2 , CO, NO, O 3There are 4 parameters in total, and the SDS018 sensor produced by Jinan Nuofang Electronic Technology Co., Ltd. is used to measure 2 parameters of PM2.5 and PM10 by light scattering method. The sensors used in Zhuoyi eq...

Abstract

The invention discloses a method for real-time calibration of air quality data using error transmission, which is characterized in that: firstly, the model is initialized, and then national standard data and Zhuoyi equipment data of the latest time period are collected, and kriging interpolation is performed on the collected national standard data , to obtain the national standard interpolation data whose sampling frequency is equal to that of Zhuoyi equipment; secondly, to model the national standard interpolation data and Zhuoyi equipment data based on the Bagging model; Perform data calibration to obtain the calibration value; finally wait for the collection of the latest national standard data, and update the calibration error based on the newly collected national standard data, and pass the error to the next model. This method performs model verification on the measured data in Yixing. This method can effectively improve the precision and accuracy of low-precision equipment, and can be deployed regionally and applied to the actual production environment.

Description

technical field [0001] The invention belongs to the technical field of real-time calibration methods for air quality data, in particular to a real-time calibration method for air quality data using error transmission. Background technique [0002] With the development of industrialization in our country, the problem of environmental pollution is becoming more and more serious. In recent years, my country has gradually attached importance to environmental issues, and the degree of environmental pollution in my country has gradually decreased, but there is still a big gap compared with developed countries. At present, monitoring air environment quality is an effective means to control air pollution. Real-time monitoring of the air quality in industrial areas can effectively monitor the pollution discharge level of enterprises and strictly control the air quality environment. However, the current high-precision and high-accuracy air quality monitoring stations use sensors tha...
