[0051] The data acquisition module 1 4 and the data acquisition module 2 5 are installed at different positions inside the detection box 1, and the collected soil greenhouse gas data are converted into digital signals for centralized storage and transmission. In the process of collecting data, the data is pre-processed;

[0052] The communication module uses wireless communication and wired communication to transmit the data collected by the data acquisition module 1 4 and the data acquisition module 2 5 to the original factory server or monitoring center;

[0053] The communication module includes: wireless communication and wired communication, and the wired communication of the communication module is connected to the data acquisition module 1 4 and the data acquisition module 2 5 through cables, and the communication module is connected to the data processing module through Bluetooth transmission;

[0054] The power control module uses cables to connect the sensor module 7, the data acquisition module one 4, the data acquisition module two 5, the communication module and the data processing module for unified power supply, supporting the monitoring system for soil greenhouse gas emission monitoring;

[0055] The data processing module receives the data information obtained by the data acquisition module 1 4 and the data acquisition module 2 5 through the communication module, receives the soil greenhouse gas data and the soil temperature and humidity data for classification and storage, and analyzes the soil greenhouse gas emissions;

[0062] The detection box 1 and the soil sealing ring 2 form a static box covering the soil surface, and the static box is located at the soil greenhouse gas emission position for the data acquisition module 1 4 and the data acquisition module 2 5 to collect soil greenhouse gas data. The data collected by the data acquisition module 1 4 and the data acquisition module 2 5 enter the communication module through the cable, and the power control module supplies power to the data acquisition module 1 4, the data acquisition module 2 5, the temperature and humidity detector 6, the sensor module 7 and the electromagnetism coil 10 through the cable. The power supply of the electromagnetism coil 10 is inserted into the soil to control the depth of the temperature and humidity detector 6.

[0063] The temperature and humidity detector 6 passes through the positioning plug plate 3 and is inserted into the soil detection area, and the positioning sleeve 9 installed in the through hole of the positioning plug plate 3 covers the soil surface. The top of the temperature and humidity detector 6 is installed inside the positioning frame 12, and the electromagnetism coil 10 and the telescopic spring column 11 symmetrically arranged on both sides of the positioning frame 12 support the temperature and humidity detector 6 to take off and lower.

[0064] The working process of the data acquisition module 1 4 and the data acquisition module 2 5 includes: greenhouse gas data acquisition inside the detection box 1, storage of the acquired data, temperature and humidity detector 6, data final processing and data remote transmission, and the data acquisition of the data acquisition module 1 4 and the data acquisition module 2 5 comes from the sensor module 7. The sensor module 7 is installed inside the detection box 1, and the detection port of the sensor module 7 is provided with a connecting pipe 8, and the sensor module 7 is connected to the data acquisition module 1 4, and the data acquisition module 1 4 and the data acquisition module 2 5 are installed inside the detection box 1;

[0065] In conjunction with the accompanying drawings Figure 1-9 As shown, when in use, the soil sealing ring 2 is installed at the bottom of the detection box 1, and the positioning plug plate 3 set inside the detection box 1 is located. Figure 7-9 As shown, the detection box 1 cooperates with the soil sealing ring 2 to cover the soil area that needs to be detected, so that the detection box 1 and the soil sealing ring 2 form a static box for accurate control of the sample state. The data acquisition module 4 located at the upper end of the detection box 1 provides an installation position for the sensor module 7. At the same time, the sensor of the sensor module 7 is connected to the chip LI-8250 of the data acquisition module 4 for multi-channel gas collection and processing. The carbon dioxide sensor, oxygen sensor, methane sensor, nitrous oxide sensor and nitric oxide sensor of the sensor module 7 cooperate with the connecting pipe 8 to detect the gas inside the detection box 1. The telescopic spring column 11 and the positioning frame 12 arranged at the upper end of the positioning plug plate 3 form an inverted U-shaped structure to provide a lifting space for the temperature and humidity detector 6. The electromagnetism coil 10 is matched with the telescopic spring column 11. The power supply connection of the power control module is combined. After being energized, the electromagnet coil 10 generates magnetic attraction. The metal sheet at the top of the telescopic spring column 11 pushes the positioning frame 12 to drive the temperature and humidity detector 6 to penetrate into the positioning sleeve 9, so that the temperature and humidity detector 6 is inserted into the soil to perform data detection on the soil temperature and soil humidity. After the electromagnet coil 10 is powered off, the metal sheet at the top of the telescopic spring column 11 drives the positioning frame 12 to lift and separate.

The data acquisition module 2 5 is connected to the power control module to realize intelligent detection. When in use, according to the preset time interval or event trigger condition, the data acquisition module is controlled to transmit the collected data to the remote server or monitoring through the communication module.

[0066] Working principle: When using the intelligent online monitoring system for soil greenhouse gas emissions, the greenhouse gases emitted in the soil area covered by the detection box 1 are first detected through the sensor module 7 through the internally arranged carbon dioxide sensor, oxygen sensor, methane sensor, nitrous oxide sensor and nitric oxide sensor. All sensors use high-precision and high-stability gas sensors, which can accurately measure the concentrations of different greenhouse gases in the soil. As the data detected by the sensors are transmitted through wired communication, the data are concentrated into the data acquisition module 1 4 and the data acquisition module 2 5 for digital information conversion and classified storage. At the same time, the data detected by the temperature and humidity detector 6 are synchronously collected by the data acquisition module 1 4 and the data acquisition module 2 5, and then signal conditioning and analog-to-digital conversion are performed to convert the analog signal into a digital signal and store it. The gas data collected by the data acquisition module 1 4 and the data acquisition module 2 5 are compared with the threshold data of the warning information triggering conditions of the abnormal warning module. When the collected data value is close to the threshold of the warning event triggering conditions, the communication module will collect the data and the alarm information of the triggered warning event. At the same time, the control chip of the battery control module transmits the collected data and the alarm information of the triggered warning event through the communication module according to the preset time interval or event triggering conditions. When the data acquisition enters the data processing module, it will be used in combination with the Hampel filter, flux instrument and gas chromatograph to classify and store the received soil greenhouse gas data and soil temperature and humidity data, and perform double data outlier processing, data filtering and smoothing processing, and analyze soil greenhouse gas emissions, monitor soil spatial distribution analysis and greenhouse gas time series analysis.
