Obviously, the drawings described below are only some embodiments described in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0052] Figure 1 This is a schematic diagram of the present invention. DETAILED DESCRIPTION

[0053] like Figure 1 As shown, a soil aeration intelligent control system includes

[0054] Data acquisition module: used to obtain soil data and plant data in the area where the aeration pipe is located; also used to obtain the distance between the aeration pipe and the air compressor and the historical operation data of the air compressor;

[0055] An information collection node is set in the area where each aeration pipe is located, and a corresponding data collection unit is set in the information collection node to obtain soil data and plant data in the area where the aeration pipe is located through the data collection unit;

[0056] The soil data includes soil temperature, soil moisture and soil oxygen content;

[0057] The historical operation data includes the corresponding output pressure of the air compressor when it is running at various powers;

[0058] The plant data includes plant species and the growth period of the plant.

[0059] Pressure acquisition module: processes soil data to obtain the pressure index of each aeration pipe. Based on the pressure index and the distance between each aeration pipe and the air compressor, the output pressure of the air compressor is obtained.

[0060] Number each aeration tube, and the number is represented by i, where i = 1, 2...n, and n represents the total number of aeration tubes;

[0061] Preprocessing the soil data to obtain standard soil data; the standard soil data includes: standard soil temperature, standard soil moisture and standard soil oxygen content; the preprocessing includes: removing outliers and normalizing;

[0062] In detail, the soil data were processed to remove outliers based on the 3σ principle, and the Z-Score method was used to normalize the soil data after removing outliers;

[0063] Preset suitable temperature range, suitable humidity range and suitable oxygen content range;

[0064] Specifically, the determination of suitable temperature, humidity, and oxygen ranges takes into account factors such as plant species, plant growth cycle, and season. Accurate range determination enables more accurate calculation of the pressure index of the aeration tube and a more ideal aeration effect.

[0065] The temperature difference wd is obtained based on the standard soil temperature and the suitable temperature range i ;According to the standard soil moisture and humidity suitable range, the humidity difference sd is obtained i ;According to the standard soil oxygen content and the suitable oxygen content range, the oxygen content difference hyl i ;

[0066] In detail, the temperature difference wd iSpecifically: when the standard soil temperature is within the temperature suitable range, the temperature difference is 0; when the standard soil temperature is greater than the maximum value of the temperature suitable range, the maximum value of the temperature suitable range is subtracted from the standard soil temperature, and the result is the temperature difference wd i When the standard soil temperature is lower than the minimum value of the suitable temperature range, the minimum value of the suitable temperature range is subtracted from the standard soil temperature, and the result is taken as the temperature difference wd i ;

[0067] In detail, the humidity difference sd i and oxygen content difference hyl i The method of obtaining the temperature difference wd is as follows: i How to obtain it;

[0068] Specifically, the higher the humidity, the more aeration is needed, because a certain amount of humidity can be removed during the aeration process; the higher the temperature, the more aeration is needed, because some heat can be removed during the aeration process; the higher the oxygen content, the less aeration is needed, because the main effect of aeration is to increase the oxygen content. When the oxygen content is sufficient, the aeration volume can be appropriately reduced.

[0069] The pressure index YLZ of the corresponding aeration pipe is obtained according to the temperature difference, humidity difference and oxygen content difference. i ,in:

[0070]

[0071] Among them, a1, a2 and a3 represent the corresponding weight factors;

[0072] Specifically, the pressure index is a quantitative indicator derived from a combination of soil temperature, humidity, and oxygen content. It accurately reflects the actual soil condition and aeration requirements in the area where each aeration tube is located. The higher the pressure index, the higher the soil's aeration requirements.

[0073] According to the pressure index YLZ of the aeration pipe i Get the aeration difference BQC of the aeration tube i ;

[0074] Specifically, a pressure index threshold is preset. When the pressure index of the aeration pipe is less than or equal to the pressure index threshold, the aeration difference is 0. When the pressure index of the aeration pipe is greater than the pressure index threshold, the pressure index threshold is subtracted from the pressure index of the aeration pipe, and the result is used as the aeration difference BQC of the corresponding aeration pipe. i ;

[0075] The adjustment coefficient corresponding to each aeration pipe is obtained according to the distance between each aeration pipe and the air compressor;

[0076] Specifically, the pressure loss during air transmission varies depending on the distance between the aeration pipe and the air compressor. The greater the distance, the greater the pressure loss. To ensure that each aeration pipe can obtain the pressure required for soil aeration, the aeration pipes need to be compensated based on the distance. An adjustment coefficient is calculated and set accordingly based on the distance. The greater the distance, the greater the adjustment coefficient. This allows for reasonable compensation for the pressure loss caused by distance when calculating the output pressure of the air compressor.

[0077] Specifically, several distance intervals are set, and different distance intervals correspond to different adjustment coefficients. The larger the distance value, the larger the corresponding adjustment coefficient. The distance intervals between each aeration pipe and the air compressor are matched, so as to obtain the adjustment coefficient k corresponding to each aeration pipe. i ;

[0078] The pressure indication value YZS of the air compressor is obtained based on the adjustment coefficient and the aeration difference, where:

[0079]

[0080] Get the output pressure of the air compressor according to the pressure indication value YZS;

[0081] In detail, an amplification factor is preset, and a result of multiplying the amplification factor by the pressure indication value is used as the output pressure of the air compressor.

[0082] Power adjustment module: processes the historical operating data of the air compressor to obtain the calibration coefficient of the air compressor, and adjusts the output power of the air compressor according to the calibration coefficient and output pressure;

[0083] Take the average value of the output pressure of the air compressor at each power as the actual pressure of the corresponding power;

[0084] According to the actual pressure and standard pressure of the air compressor under various powers, the calibration coefficient of the air compressor is obtained;

[0085] A power-actual pressure curve is drawn in a rectangular coordinate system as an operating curve, and an integral operation is performed on the operating curve to obtain a result as an operating integral;

[0086] A power-standard pressure curve is drawn in a rectangular coordinate system as a comparison curve, and an integration operation is performed on the comparison curve, and the result obtained is used as the comparison integral;

[0087] Divide the operating integral by the comparison integral and use the result as the calibration coefficient of the air compressor;

[0088] Specifically, when the air compressor operates at different power levels, the actual output pressure will deviate from the standard pressure. This deviation can be corrected by processing historical operating data to obtain a calibration coefficient. This coefficient reflects the degree of difference between the actual output pressure of the air compressor and the standard pressure, providing a basis for subsequent adjustments to the output power, ensuring that the output pressure better meets the standard requirements, thereby improving the aeration effect.

[0089] According to the preset standard pressure-standard power comparison table, the standard power corresponding to the output pressure is obtained, and the output power is obtained according to the standard power and the calibration coefficient, where:

[0090] Output power = standard power / calibration factor;

[0091] According to the output power obtained, the power of the air compressor is adjusted to the output power.

[0092] Timer module: obtains the aeration time and aeration interval of each aeration tube according to the pressure index of each aeration tube and the plant data of the area where each aeration tube is located;

[0093] According to the plant species and plant growth cycle in the area where each aeration tube is located, the corresponding demand coefficient xq is extracted from the preset database;

[0094] Specifically, the larger the demand coefficient is, the stronger the demand for oxygen by plants in the current area is. When setting the aeration interval and aeration time, the aeration time will be longer and the aeration interval will be shorter.

[0095] According to the pressure index of each aeration tube, the preset aeration time of each aeration tube is obtained and preset aeration intervals

[0096] Specifically, several pressure index intervals are preset, and different intervals correspond to different aeration times and aeration intervals. The larger the pressure index, the longer the corresponding aeration time, but the shorter the corresponding aeration interval;

[0097] According to the preset aeration time Preset aeration interval And the demand coefficient xq, the aeration time SJ of each aeration tube is obtained i and aeration interval JG i ,in:

[0098]

[0099] Among them, β represents the empirical index corresponding to the preset aeration time, and ε represents the empirical index corresponding to the preset aeration interval.

[0100] Abnormal analysis module: Analyze the aeration difference of each aeration pipe and take corresponding measures according to the analysis results;

[0101] When the aeration difference of a certain aeration tube is greater than 0, the collection node corresponding to the aeration difference is marked as the starting node;

[0102] The waiting node value n is preset. If the aeration difference of the corresponding aeration pipe at n collection nodes after the starting node is always greater than 0, the analysis interval is obtained according to the waiting node value n and the starting node;

[0103] Specifically, the nth node after the starting node is marked as the ending node, and the time interval enclosed by the starting node and the ending node is marked as the analysis interval;

[0104] Obtain all aeration tubes with aeration difference values greater than 0 in the analysis interval as analysis aeration tubes, process the aeration difference values of the analysis aeration tubes in the analysis interval, and obtain abnormal aeration tubes;

[0105] Specifically, if the aeration difference of the analysis aeration tube has returned to 0 in the analysis interval, the corresponding analysis aeration tube is recorded as a normal aeration tube;

[0106] If the aeration difference of the analysis aeration tube in the analysis interval is not 0, calculate the aeration efficiency of the corresponding analysis aeration tube:

[0107] Aeration efficiency = aeration difference / time;

[0108] Among them, aeration difference refers to the difference between the aeration difference corresponding to the first time the aeration difference value of the analysis aeration tube is greater than 0 in the analysis interval and the aeration difference corresponding to the end node of the analysis aeration tube; time refers to the time difference between the time corresponding to the first time the aeration difference value of the analysis aeration tube is greater than 0 in the analysis interval and the time corresponding to the end node, in seconds;

[0109] A preset aeration efficiency threshold is set. If the aeration efficiency of the analysis aeration tube is less than the aeration efficiency threshold, the corresponding analysis aeration tube is marked as an abnormal aeration tube.

[0110] Specifically, a preset aeration efficiency threshold provides a clear standard for determining whether an aeration tube is abnormal. If the aeration efficiency of an aeration tube is less than this threshold, it indicates that the aeration effect has not met the system's expected level and a fault is likely present. This helps the system accurately locate problematic aeration tubes and promptly identify those with poor aeration performance but no obvious abnormalities or irregular changes in the aeration difference, thus avoiding missing potential faults.

[0111] Count the number of abnormal aeration tubes. If the number of abnormal aeration tubes is less than y, then repair the corresponding abnormal aeration tubes. If the number of abnormal aeration tubes is greater than or equal to y, then repair the air compressor. Where y is the preset abnormal aeration tube threshold.

[0112] Specifically, when the number of abnormal aeration tubes is less than y, it is likely that some aeration tubes have individual problems, such as blockage or damage, which affects the aeration effect. Inspection and repair of these individual abnormal aeration tubes can accurately locate and resolve local faults.

[0113] Specifically, if the number of abnormal aeration tubes is greater than or equal to y, it indicates that the problem may lie with the core equipment, the air compressor. Because the air compressor provides the air source for all aeration tubes, if it malfunctions, such as unstable pressure or insufficient air supply, it will cause abnormal aeration in multiple aeration tubes. At this time, inspecting and repairing the air compressor can solve the problem at the root and ensure the stable operation of the entire aeration system.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
