Embodiment Construction

[0042] like figure 1 , The multi-node atmospheric environment detection system is mainly composed of an aerosol particle sampling device, a lower computer data processing device, a communication transmission device, and an upper computer acquisition and processing device. Among them, the aerosol particle sampling device detects the aerosol through the backscattering of particles, and then obtains the concentration of atmospheric particles; and collects the content of carbon dioxide and volatile organic compounds, as well as temperature and humidity data. The lower computer data processing device collects the data of each sensor in the aerosol particle sampling device, processes and packs it; and displays the atmospheric parameters of each aerosol particle sampling device. The communication transmission device provides short-distance or long-distance transmission for the data collected by each aerosol particle sampling device. The upper computer acquisition and processing devi...

Abstract

The invention relates to a multi-node atmospheric environment detection system. The multi-node atmospheric environment detection system comprises: aerosol particulate matter sampling devices, used for detecting aerosol by means of back scattering of the aerosol to further obtain the concentration of atmospheric aerosol; a lower computer data processing device, used for collecting, and processing and packaging data of each sensor in the aerosol particulate matter sampling devices, and displaying atmospheric parameters of each aerosol particulate matter sampling device; a communication transmission device, used for providing a short-distance transmission manner or a long-distance transmission manner for the data collected by each aerosol particulate matter sampling device; an upper computer collection and processing device, used for converting frame data transmitted by the aerosol particulate matter sampling devices into atmospheric environment parameters, monitoring air quality, giving an alarm when the air quality is lower than a set value, and recording the atmospheric environment parameters. The multi-node atmospheric environment detection system has the beneficial effects that the environment detection equipment can realize automatic collection and recording of the data and achieve a wireless data transmission function, and is easy to control and adjust, and the system is high in stability.

Description

technical field [0001] The invention relates to the field of meteorology, in particular to a multi-node atmospheric environment detection system and method. Background technique [0002] As a component of the atmosphere, aerosol plays an important role in many processes such as atmospheric optics. PM2.5 refers to particles suspended in the air with a size smaller than 2 μm. Aerosols can be divided into pollution sources caused by natural causes and pollution sources caused by human causes according to their sources. Natural sources such as blowing sand, dust storms, volcanic eruptions, etc.; man-made sources mainly include vehicle exhaust emissions, industrial exhaust emissions, and the combustion of fossil and non-fossil fuels. A large amount of particulate matter remaining in the air has had a major impact on people's production and life, especially the toxic particulate matter in the air will cause great harm to the human body. However, at present, the collection of ae...
