Atmospheric environment monitoring scheme for 4G industrial router

Atmospheric environment monitoring is the concentration of pollutants in the atmospheric environment , Observe 、 Analyze its changes and the determination process of its impact on the environment . Air pollution monitoring is to determine the types and concentrations of pollutants in the atmosphere , Observe its space-time distribution and change law .R40 4G Industry VPN Wireless router is used in smart environmental protection industry to realize wireless remote video 、 rainfall 、 The wind speed 、 wind direction 、PM2.5、PM10、 Temperature and humidity 、 Data acquisition of air pressure and automatic or remote control of fog gun machine .

Air pollution monitoring (air pollution monitoring) It refers to the determination of the types and concentrations of pollutants in the atmosphere , Observe the process of its space-time distribution and change law . The purpose of air pollution monitoring is to identify pollutants in the atmosphere , Master its distribution and diffusion law , Monitor the emission and control of air pollution sources .

The confirmed air pollutants are 100 Varied , These pollutants are distributed in the atmosphere in the form of molecules and particles . Molecular pollutants mainly include sulfur oxides 、 Nitrogen oxides 、 carbon monoxide 、 ozone 、 Halogenated hydrocarbon 、 Hydrocarbons, etc . Particulate pollutants mainly include dust 、 Total suspended particulate matter 、 Floating dust, etc . Because air pollution is closely related to meteorological conditions , Therefore, wind direction should be included in air pollution monitoring 、 The wind speed 、 The temperature 、 pressure 、 The intensity of solar radiation 、 Determination of meteorological parameters such as relative humidity . Air pollution monitoring is the basis of air quality monitoring .

Air quality monitoring (air quality monitoring) It refers to pollutants that can represent air quality in an area, such as PM10、SO2 and NO2 Carry out spot monitoring , And by monitoring data , The process of evaluating atmospheric environmental quality by comparing the concentration classification table of air quality pollutants issued by the Ministry of environmental protection . Atmospheric quality monitoring is usually based on the scale of a region 、 Distribution and intensity of air pollution sources 、 weather conditions 、 Landform and other factors , Select several or more representative measuring points in this area ( Atmospheric sampling point ), Carry out regular monitoring of specified projects .

​

The mandatory monitoring items for air quality stipulated by China include sulfur dioxide 、 Respirable particles 、 Carbon monoxide and nitrogen dioxide , Other projects can be selected and tested in conditional areas , For example, ozone 、 Carbon monoxide, etc . Besides , According to the characteristics of regional air pollution , Selective determination of benzo (a) pyrene 、 lead 、 Total suspended particulate matter 、 Fluoride and other items . According to the monitoring results , Compare with national standards 《 Ambient air quality standard 》(GB3095-1996) Evaluate , So we can draw a conclusion about the quality of regional atmospheric environment .
