All data acquisition terminals arranged in one monitoring point are in data connection with the same edge computing device; one edge computing device is only connected with the data acquisition terminal in one monitoring point and is not connected with the data acquisition terminals in other monitoring points; the server is connected to at least one edge computing device and at least one user terminal.
The monitoring equipment is used for acquiring real-time data of various detection objects; the weather collecting equipment is used for collecting real-time weather parameters.
In one embodiment, the detection substance is volatile organic compounds in the atmospheric environment, including benzene series, organic chloride, freon series, organic ketone, amine, alcohol, ether, ester, acid, petroleum hydrocarbon compound, and the like;
in one embodiment, the real-time data of the detection object is the content of volatile organic compounds in the atmospheric environment, i.e., the content of benzene series, organic chlorides, freon series, organic ketones, amines, alcohols, ethers, esters, acids, petroleum hydrocarbon compounds, and the like in the atmospheric environment.
In one embodiment, the meteorological data is a meteorological five parameter, and the meteorological five parameter includes temperature, air pressure, humidity, wind direction and wind speed.
The edge computing device is used for receiving various detection object data and meteorological parameters, determining a potential pollution source by adopting a threshold judgment method and a quadrant division method, and uploading the potential pollution source to the server, and specifically:
(1) the edge computing device is used for judging whether the data of various detection objects exceed a threshold value or not, the detection objects exceeding the threshold value are judged to be over-standard detection objects, specifically, the edge computing device is used for receiving real-time data of the detection objects transmitted by the terminal through edge computing, comparing various data through various detection object data threshold values set by the system, and judging whether the data exceed the threshold value or not through comparing the numerical values.
(2) The edge computing equipment matches a pollution source causing the overproof detection object in the database to serve as a pollution source to be confirmed, four quadrants are divided by taking the geographic coordinates of monitoring points where data acquisition terminals (corresponding to the data acquisition terminals) connected with the edge computing equipment are located as original points, the quadrant where the pollution source is located is judged by combining the wind direction angle in the meteorological parameters, and the pollution source to be confirmed in the quadrant is found out to serve as the potential pollution source.
