The adjustment rod 6 moves downward to make the slide plate 509 slide inside the guide groove 508, thereby increasing the stability of the movement of the moving block 510. The movement of the moving block 510 makes the block 511 disengage from the toothed disc 504, and then the turning handle 505 is rotated to make the toothed disc 504 drive the rack 507 to move, thereby facilitating the adjustment of the height of the support rod 101. After the adjustment is completed, the limit plate 607 is released, and the block 511 will be re-clamped on the toothed disc 504 through the elastic force of the second spring 605, thereby facilitating the fixing of the position of the support rod 101.

[0073] A solar panel 7 is installed on the top of the monitoring device body 1, and electric energy is obtained through the solar panel 7 to provide power for the monitoring instrument 110;

[0074] The monitor 110 used in the present invention can be used for infrared spectroscopy when used in outdoor environments: an infrared spectrometer can determine the concentration of a specific gas by analyzing the absorption of infrared light by gas molecules. This method has high sensitivity and can be used to detect a variety of greenhouse gases.

[0075] It is further explained that the monitor 110 used in the present invention is a greenhouse gas emission analyzer (Gasboard-3000GHG), which adopts self-microflow infrared semi-chamber gas sensing technology to achieve accurate measurement of greenhouse gases such as CO2, CH4, N2O and CO gas concentration changes in flue gas at the same time. The measurement range can be as low as 200ppm, the accuracy is as high as 1%FS, and it has strong anti-gas cross interference ability and lower drift.

[0076] In this embodiment, if Fig.10 As shown, it includes a carbon dioxide collection module, a methane collection module, a nitrous oxide collection module, a sulfur hexafluoride collection module, a hydrochlorofluorocarbon collection module and a nitrogen trifluoride collection module arranged in the monitor 110;

[0077] A carbon dioxide acquisition module, a methane acquisition module, a nitrous oxide acquisition module, a sulfur hexafluoride acquisition module, a hydrochlorofluorocarbon acquisition module and a nitrogen trifluoride acquisition module coupled with a preprocessing module;

[0078] The preprocessing module is coupled to the gas analyzer, and the gas analyzer is coupled to the data reprocessing unit;

[0079] The data reprocessing unit is coupled to the data transmission module;

[0080] The data transmission module is coupled to the backend server.

[0081] By setting a carbon dioxide acquisition module, a methane acquisition module, a nitrous oxide acquisition module, a sulfur hexafluoride acquisition module, a hydrochlorofluorocarbon acquisition module and a nitrogen trifluoride acquisition module in the monitor 110, it is possible to acquire the carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrochlorofluorocarbon and nitrogen trifluoride gases entering the monitor 110, convert the acquired information into an electrical signal and transmit it to the preprocessing module, and after being processed by the preprocessing module, transmit it to the gas analyzer to analyze and process the carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrochlorofluorocarbon and nitrogen trifluoride gases. At the same time, the gas analyzer obtains a continuous power supply through the solar panel 7. After the gas analyzer completes the analysis and judgment, it is transmitted to the data reprocessing unit to filter, sort and amplify the data transmitted to the data reprocessing unit, and then transmit it to the background server through the data transmission module.

[0082] In this embodiment, the preprocessing module processes the data including the following steps:

[0083] Process missing values, smooth noise, and identify and process outliers in the collected data;

[0084] Combine data from multiple sources into a single consistent data store;

[0085] Normalize, standardize, discretize data, and construct data cubes;

[0086] The data is processed for missing values, smoothing noise, identifying and processing outliers. If the proportion of missing values ​​in the data set is small and the missing values ​​do not affect the overall trend of the data, the records containing missing values ​​are directly deleted;

[0087] If the proportion of missing values ​​is high, or the information of missing values ​​is very important for analysis, choose to fill missing values;

[0088] Smoothing noise includes moving average: replacing the current data point with the average of a certain number of recent data points to eliminate random noise;

[0089] Exponential smoothing: predicts current values ​​based on past observations, giving more weight to recent data points;

[0090] Regression smoothing uses a regression model, such as polynomial regression, to fit the data trend and replace the original data with the model predictions.

[0091] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
