Abstract

The invention discloses a local wide-range VOC monitoring device which is based on an Internet of Things platform and is convenient to calibrate, and provides a calibration method suitable for the device. The local wide-range VOC monitoring device uses a PID sensor as a VOC monitoring sensor, data acquired by the sensor and other sensors are subjected to signal conversion processing, positioning information of the position where terminal equipment is located is collected and transmitted to a system server, and the system server carries out storage, analysis, calibration operation and the like. Compared with a traditional local wide-range VOC monitoring mode, the local wide-range VOC monitoring device can realize remote automatic calibration at the server side, and does not need to spend a large amount of manpower to calibrate the VOC monitoring terminals one by one; and the local wide-range VOC monitoring device has the characteristics of high automation degree, low calibration cost and low manpower cost, and is widely applied to the field of local wide-range VOC calibration monitoring.

Description

technical field [0001] The invention relates to the field of local wide-range VOC monitoring, in particular to a local wide-range VOC monitoring device and a calibration method based on an Internet of Things platform and convenient for calibration. Background technique [0002] VOC (volatile organic compound) monitoring plays an important role in atmospheric environment monitoring. In some production occasions, the pollution of toxic VOC will cause serious harm to the human body. VOC content is an important indicator for air quality assessment. Especially under the current situation of serious ozone pollution, the significance of controlling VOCs for ozone governance is prominent. Traditional large-scale detection machines are expensive, the layout is not flexible enough, and data collection is not convenient enough. The PID sensor embodies the advantages of high precision and low cost in VOCs measurement. However, due to the simple principle of its detection signal, the ...
