Description

Technical Field

[0001] The present invention relates to the technical field of data acquisition, and in particular to a data acquisition 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 evaluating ecosystem carbon cycles, guiding agricultural practices and formulating emission reduction strategies.

[0003] Publication number CN115508515A discloses a data collection system for soil greenhouse gas emissions, including the following steps: S1: Acquisition of monitoring points: An intelligent mobile device utilizes an automatic navigation system to achieve coverage of monitoring points and moves the intelligent mobile device to the detection point. The intelligent mobile device identifies and manually locates a location suitable for detection based on the route movement. A detection point can also be set at a certain distance along the route, and the GPS location 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, placing the sealed box on the soil surface. This solution combines the soil box method and the sensor method, and innovatively forms a soil greenhouse gas detector device that can be used for in-situ detection of different locations. This detection device not only avoids laborious and time-consuming manual sampling, but also enables 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 representativeness 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 based on 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

[0006] The main purpose of the present invention is to provide a data collection and early warning system for soil greenhouse gas emissions to solve the problems raised in the above background.

[0010] The data early warning terminal is used to receive the judgment results of environmental dynamic changes in real time, and predict in real time whether the current trend of environmental dynamics will affect the soil greenhouse gas emission data of the next cycle based on the dynamic changes. When predicting the impact on the soil greenhouse gas emission data of the next cycle, the environmental parameter compensation correction value is calculated in real time to predict in advance whether the soil greenhouse gas emissions are abnormal based on the environmental changes.

[0022] The parameter comparison unit is used to compare the emission data after serial number arrangement with the standard parameters, specifically, to calculate the difference between the emission data after serial number arrangement and the standard parameters. If the difference is less than or equal to 0.02 and greater than or equal to -0.02, it indicates that the soil greenhouse gas emission data of the corresponding area is normal; if the difference is greater than 0.02 or less than -0.02, it indicates that the soil greenhouse gas emission data of the corresponding area is abnormal;

[0023] The regional early warning unit is used to report abnormal soil greenhouse gas emission data in the corresponding area to the system and issue a voice alarm;

[0031] The optimization parameter unit is used to calculate the difference between the environmental parameters monitored in real time and the environmental limit values. If the difference is less than or equal to 0.1 and greater than or equal to -0.1, it indicates that the soil greenhouse gas emission environmental parameters in the corresponding area are normal. If the difference is greater than 0.1 or less than -0.1, it indicates that the soil greenhouse gas emission environmental parameters in the corresponding area are abnormal.

[0032] The environment tracking module includes an environment self-tracking unit and an environment early warning unit;

[0033] The environmental self-tracking unit is used to track the difference between the current environmental parameters and the environmental limit values ​​in real time through a data tracker;

[0039] The impact analysis module is used to calculate the average value of the environmental parameters arranged in sequence according to the period, and set the daily environmental parameter standard value, counting one day as one period, and calculating the average value of the daily environmental parameters for five periods. If the average values ​​of the daily environmental parameters for the five periods are all greater than the standard value of the daily environmental parameters, it is predicted that the environmental dynamics of the current trend will affect the soil greenhouse gas emission data of the next period. If at least one of the average values ​​of the daily environmental parameters for the five periods is less than the standard value of the daily environmental parameter, it is predicted that the environmental dynamics of the current trend will not affect the soil greenhouse gas emission data of the next period.

[0040] The abnormal warning module is used to send a voice alarm to the reporting system when it is predicted that the environmental dynamics of the current trend will affect the soil greenhouse gas emission data of the next cycle.

[0041] The abnormality compensation module includes a gas compensation unit and a compensation tracking unit;

[0042] The gas compensation unit is used to calculate the soil greenhouse gas emission correction value of the corresponding area in real time based on environmental parameters. The environmental parameters include soil moisture content. The calculation formula of the soil greenhouse gas emission correction value is as follows:

If abnormal, the environmental parameters are adjusted in real time. In addition, based on the daily and seasonal changes in the environment, it is possible to determine in real time whether the soil greenhouse gas emission data meets the standards, thereby avoiding collection anomalies during soil greenhouse gas emission data collection and further reducing data collection errors.

Specifically, the difference between the emission data after serial number arrangement and the standard parameters is calculated. If the difference is less than or equal to 0.02 and greater than or equal to -0.02, it means that the soil greenhouse gas emission data of the corresponding area is normal. If the difference is greater than 0.02 or less than -0.02, it means that the soil greenhouse gas emission data of the corresponding area is abnormal.
