Description

Technical Field

[0001] The present invention relates to the technical field of data collection, and in particular to a data collection and early warning system for soil greenhouse gas emissions. Background Art

[0002] Data collection of soil greenhouse gas emissions is the process of collecting and analyzing greenhouse gases produced in the soil under laboratory or field conditions by using specific equipment and methods. As one of the important carbon reservoirs on the earth's surface, soil plays a key role in the global carbon cycle. These two gases are major greenhouse gases. Accurately measuring the emissions of these gases is of great significance for assessing ecosystem carbon cycles, guiding agricultural practices and formulating emission reduction strategies.

[0003] Publication No. CN115508515A discloses a data collection system for soil greenhouse gas emissions, including the following steps: S1: Acquisition of monitoring points, the intelligent mobile device uses the automatic navigation system to achieve coverage of the monitoring points, moves the intelligent mobile device to the detection point, and the intelligent mobile device moves according to the route, identifies and manually locates a location suitable for detection, or sets a detection point at a certain distance on the route, and the GPS positioning of the detection point will be recorded synchronously; S2: Data collection, after the intelligent mobile device arrives at the detection point, the mechanical arm on the intelligent mobile device is raised and then lowered, so that the sealed box is placed on the soil surface. This solution combines the soil box method and the sensor method, and innovates to form a soil greenhouse gas detector device that can be used for in-situ detection of different locations. This detection equipment can not only avoid laborious and time-consuming manual sampling, but also realize convenient detection and evaluation of soil greenhouse gas emissions.

[0004] After searching the above patents, it was found that there are still some deficiencies in the process of soil greenhouse gas emissions: 1. Current soil greenhouse gas emission research often focuses on specific land cover types and climate zones, resulting in insufficient spatial representation of soil greenhouse gases. This deviation may lead to inaccurate estimates of the total amount of soil greenhouse gas emissions and affect the accuracy of soil greenhouse gas data collection; 2. Since the environment is constantly changing, soil greenhouse gas emissions have obvious daily and seasonal variations. However, in the daily and seasonal variations, it is impossible to ensure the stability of soil greenhouse gas emissions in real time based on environmental information, that is, it is impossible to judge in real time whether the soil greenhouse gas emission data meets the standards, resulting in possible fault anomalies in the soil greenhouse gas emission data; 3. The existing data acquisition system cannot capture the impact of these changes on soil greenhouse gas emissions in real time according to environmental changes, and cannot predict in advance whether soil greenhouse gas emissions are abnormal according to environmental changes, resulting in limitations in soil greenhouse gas emission dynamics.

[0005] Therefore, a data collection and early warning system for soil greenhouse gas emissions is proposed to solve the above problems. Summary of the invention
