Portable VOC sensing network monitor

Abstract

The invention relates to a portable VOC sensing network monitor, comprising a monitor body. The monitor body comprises a shell. A main control panel, a positioning module for providing position information, a communication module for transmitting and receiving signals, a VOC sensor module for detecting VOC gas and a temperature control module for controlling the temperature of the VOC sensor module are arranged in the shell, wherein the positioning module, the communication module, the VOC sensor module and the temperature control module are connected with the main control panel. The monitor body is connected to a remote monitoring management platform via the communication module, so that display and analysis of monitor data and remote diagnosis, control and calibration of the monitor bodyare performed. The portable VOC sensing network monitor, which is accurate in measurement result and simple in structure, makes it easy to determine a pollution source and is convenient for emergencymonitoring and mobile use. Meanwhile, remote control can be realized, so that the safety of monitoring personnel is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment monitoring, in particular to a portable VOC sensor network monitor. Background technique [0002] The World Health Organization (WHO) defines a large class of organic compounds that have a boiling point of 50-260 ° C, a saturated vapor pressure of more than 133.32 Pa at room temperature, and exist in the air in the form of vapor at room temperature as volatile organic compounds (Volatile Organic Compounds, VOC). , Many substances in VOC have stimulating effects on the human body and various sense organs, and have certain toxicity. . Therefore, VOC, as the main pollutant gas in interior decoration places and the main pollutant in industry, is receiving widespread attention, and the real-time monitoring of VOC in the atmospheric environment is becoming more and more important. [0003] The volatility of VOC will change with temperature and humidity, which will have a great impact o...

Problems solved by technology

However, in general, the sensitivity of high-temperature detectors is reduced, and the sensitivity of low-temperature sensors is increased to cause sensor drift, and because the temperature response speed of the temperature sensor and the gas sensor is not the same, the compensation transition or too small lead to misjudgment

Moreover, if the temperature is too high, the life of the gas sensor will be greatly reduced in a high temperature environment, which will shorten the service life of the entire equipment and increase the difficulty of maintenance.
