Multi-component atmospheric environment gridded monitoring instrument

Abstract

The invention belongs to the technical field of environmental monitoring and particularly relates to a multi-component atmospheric environment gridded monitoring instrument. The invention aims to solve a problem that traditional atmospheric monitoring equipment has the disadvantages of a large volume, a high price and complex installation and maintenance and is difficult in satisfying higher and higher monitoring requirements. The invention provides the multi-component atmospheric environment gridded monitoring instrument which comprises a box body, a box body upper cover, a solar panel, a solar cell charging management unit, a storage battery, a switch power supply, a motherboard, a GPRS transmission module, a GPRS antenna, a GPS module, a partition switching board, a temperature and humidity sensor, a shield, an inlet humidity control unit, an air guidance fan, a PM2.5 sensor, a PM10 sensor, a gas sensor unit, and a meteorological station. Compared with the traditional atmospheric monitoring equipment, according to the atmospheric monitoring instrument, the reasonable model selection is carried out in various sensors, the humidity conditions measured by the sensors are controlled, and thus the sensors have the advantages of high accuracy, good stability, and high contrast in atmospheric gridded distribution site monitoring.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, in particular to a multi-component atmospheric environment grid monitoring instrument. Background technique [0002] At present, the air pollutants routinely monitored are mainly carbon monoxide, sulfur dioxide, nitrogen dioxide, ozone, PM 2.5 and PM 10 , mainly from dust, coal, motor vehicles, factory emissions, etc. With people's increasing emphasis on environmental protection, the demand for air quality monitoring, traffic road network emission monitoring, and industrial waste gas monitoring is gradually increasing, and it is imminent to improve the ecological environment and people's living conditions. However, traditional atmospheric monitoring equipment is bulky, expensive, and complex to install and maintain, making it difficult to meet increasingly high monitoring requirements. At present, miniaturized and low-cost sensors are constantly emerging in the market. How to ...

AI Technical Summary

Problems solved by technology

At present, most of the common small-scale grid atmospheric environment monitors are not suitable for long-term monitoring outdoors, such as the invention patent of a miniaturized air quality monitoring device and a method for detecting air quality with a miniaturized air quality monitoring device (publication number 105021779A ), when measuring the gas composition SO 2 , NO 2 , O 3 , NH 3 When using the method of membrane chemical reaction, regular sampling is required for subsequent laboratory analysis; an air quality detector for the invention patent (publication number 105548502A), when monitoring particulate matter, only PM 2.5 Monitoring was carried out, no PM 10 Monitoring is carried out, and the humidity of the particle sensor is not controlled, the measurement data is affected by relative humidity, and it is difficult to correct the data
