Detailed Implementation

[0023] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0024] Reference Figure 1 , Figure 1 A flowchart illustrating a method for acquiring soil geographic information for agricultural geographic analysis provided in this application embodiment, the method may include: Step 101: Determine the first maximum length of the first taproot and the first minimum spacing of the first lateral root of the target main crop in the target cultivated area.

[0025] In the embodiments of this application, considering that the growth of crops mainly depends on the distribution of soil nutrients, specifically reflected in the growth and distribution of their root systems, this application focuses on the first taproot and first lateral root of the target main crop in the target cultivated area. Since the influence range of a single fibrous root is small, and crops do not always have fibrous roots, they are not introduced here. Specifically, by studying the growth habits of the target main crop and using random sampling in-situ measurements, the first maximum length of the first taproot and the first minimum spacing of the first lateral roots can be obtained. The first minimum spacing of the first lateral roots is derived from the distance between the ends of each first lateral root.

[0026] Step 102: Based on the first maximum length, samples are taken in the target cultivated area to obtain a first soil sample.

[0027] In the embodiments of this application, a first soil sample can be obtained by sampling in the target cultivated area based on the first maximum length of the first straight root. The sampling point can be a point near the target main crop, the sampling direction is vertical, and the sampling length is the first maximum length.

[0028] Step 103: Based on the first minimum spacing, the first soil sample is divided into layers to obtain a layered soil sample.

[0029] In the embodiments of this application, the first soil sample can be stratified according to the first minimum spacing of the first lateral roots to obtain stratified soil samples. The number of stratified soil samples can be calculated using the first minimum spacing and the first maximum length, as shown in Equation 1 below: (Equation 1) In equation 1 above, Indicates the number of stratified soil samples. Indicates the first maximum length. Indicates the first minimum spacing. This represents the floor function. When performing stratification, the determined sampling points can be used as the starting point for stratification.

[0030] Step 104: Perform component analysis on the layered soil samples to obtain the layered soil geographic information of the target cultivated area.

[0031] In the embodiments of this application, stratified soil samples can be analyzed to obtain stratified soil geographic information of the target cultivated area. Soil composition analysis is an important means of understanding soil properties and guiding agricultural production and environmental protection. Soil composition analysis methods may include: particle size analysis, texture determination, density determination, pH determination, moisture content determination, organic matter determination, nutrient determination, heavy metal detection, microbial biomass determination, enzyme activity determination, etc.

[0032] In the embodiments of this application, a first crowdsourced map of the traffic lights at the target intersection is obtained. This first crowdsourced map is generated jointly by vehicles near the traffic lights at the target intersection. Based on the first crowdsourced map, the traffic flow of the first road corresponding to the traffic lights at the target intersection is determined. Based on the traffic flow of the first road, a first adjustment duration for the traffic lights at the target intersection is determined. Based on the first adjustment duration, the first on / off duration of the traffic lights at the target intersection is adjusted to obtain the target on / off duration. The traffic lights at the target intersection are then controlled to turn on and off based on the target on / off duration. The traffic flow near the traffic lights at the intersection can be obtained from the crowdsourced map, and an adjustment scheme for the on / off duration of the traffic lights can be derived based on the traffic flow. Finally, the on / off duration of the traffic lights is adjusted. Because the continuous on / off duration of the green light corresponding to lanes with high traffic flow is increased, the above method can alleviate traffic congestion to a certain extent and avoid the need for traffic police to control vehicle traffic. This can effectively improve the immediacy of traffic control changes and the efficiency of smooth traffic recovery.

[0033] Reference Figure 2 , Figure 2 A flowchart illustrating another method for acquiring soil geographic information for agricultural geographic analysis provided in this application embodiment, the method may include: Step 201: Determine the first maximum length of the first taproot and the first minimum spacing of the first lateral root of the target main crop in the target cultivated area.

[0034] In the embodiments of this application, the implementation of this step can be referred to the embodiment of step 101, and will not be repeated here.

[0035] Step 202: Random sampling is conducted in the target cultivated area to obtain the main crop of the sample.

[0036] In the embodiments of this application, the target cultivated area may have multiple target main crops. Random sampling can be performed in the target cultivated area to select multiple target main crops as sample main crops. The number of sample main crops can be much smaller than the total number of target main crops. The random sampling method can be determined based on the arrangement of the target main crops. If the target main crops are arranged in a single column, the sample main crops can be determined using a single random number; if the main crops are arranged in multiple columns, the sample main crops can be determined using a combination of two random numbers.

[0037] Step 203: Determine the location of the first distance between the ground surface and the second taproot of the main crop in the sample as the sampling starting point; wherein, the first distance is determined based on the second maximum length of the first lateral root.

[0038] In embodiments of this application, the sampling starting point can be a ground location at a distance of a first distance from the second taproot of the main crop being sampled. The first distance can be determined based on the second maximum length of the first lateral root; for example, the second maximum length can be used as the first distance, or the length of the projection of the second maximum length onto the ground can be used as the first distance.

[0039] Step 204: Determine the sampling endpoint location based on the first maximum length.

[0040] In embodiments of this application, the sampling endpoint location can be determined by a first maximum length. For example, starting from the location of the straight root on the ground surface, the end of the first maximum length along the straight root direction can be the sampling endpoint location, or any point within a preset range of the end can be the sampling endpoint location.

[0041] Optionally, step 204 may include the following sub-steps: Sub-step 2041: Based on the first maximum length, determine the end position of the second straight root end.

[0042] In embodiments of this application, the end position of the second straight root can be determined based on the first maximum length. The end position can be the endpoint of the first maximum length along the direction of the second straight root, starting from the point where the root is exposed on the ground.

[0043] Sub-step 2042: Determine the sampling endpoint position based on the end position.

[0044] In the embodiments of this application, the sampling endpoint position can be determined based on the end position. Specifically, the end position can be directly determined as the sampling endpoint position, or a position within a preset range near the end position can be determined as the sampling endpoint position.

[0045] Optionally, sub-step 2042 may include the following sub-steps: Sub-step A1: Based on the terminal position and the maximum distance at which the second taproot end can absorb nutrients, determine the space of the first sphere.

[0046] In the embodiments of this application, the first spherical space can be determined with the end position as the center and the maximum distance that the end of the second straight root can absorb nutrients as the radius.

[0047] Sub-step A2: Determine the sampling endpoint position in the first spherical space.

[0048] In the embodiments of this application, any position in the space of the first sphere can be determined as the sampling endpoint position.

[0049] In one possible embodiment, considering that soil samples in the space above the end position can be replaced by their lateral roots, any location within the hemispherical space below the end position can be determined as the sampling endpoint. This can result in more accurate soil samples.

[0050] In the embodiments of this application, by determining the first spherical space based on the end position and the maximum distance that the end of the second taproot can absorb nutrients, and determining the sampling endpoint position in the first spherical space, a sampling endpoint position with better compatibility with the target main crop can be obtained, which can improve the matching degree between the sampling endpoint position and the target main crop to a certain extent.

[0051] In the embodiments of this application, by determining the end position of the second straight root based on the first maximum length, and then determining the sampling endpoint position based on the end position, the sampling endpoint position can be determined by combining the first maximum length with the second straight root, which can improve the accuracy of the sampling endpoint position to a certain extent.

[0052] Step 205: Soil samples are taken based on the sampling start point and the sampling end point to obtain the first soil sample.

[0053] In the embodiments of this application, soil sampling can be performed based on the sampling start point and sampling end point to obtain a first soil sample. For example, soil sampling can be performed using the straight line formed by the sampling start point and sampling end point as the sampling route.

[0054] Optionally, step 205 may include the following sub-steps: Sub-step 2051: Determine the sampling angle of the soil sampler based on the sampling start point position and the sampling end point position.

[0055] In the embodiments of this application, the sampling angle of the soil sampler can be defined as the angle formed by the straight line connecting the sampling start point and the sampling end point and the ground surface plane.

[0056] Sub-step 2052: Based on the sampling angle, control the soil sampler to pass through the sampling start point position and the sampling end point position to perform soil sampling and obtain the first soil sample.

[0057] In the embodiments of this application, the soil sampler can be controlled to pass through the sampling start point and sampling end point according to the sampling angle to collect soil samples, thereby obtaining a first soil sample. The soil sampler can be a cylindrical hollow metal tool with an openable metal blade at the top and a knob at the bottom. When the knob is turned, the metal blade at the top changes from a retracted state to an engaged state, allowing the soil in the soil sampler to be easily removed.

[0058] In the embodiments of this application, the sampling angle of the soil sampler is determined based on the sampling start position and the sampling end position. Based on the sampling angle, the soil sampler is controlled to pass through the sampling start position and the sampling end position to collect soil samples and obtain a first soil sample. This allows for soil sampling in a convenient manner and improves the sampling efficiency of the first soil sample to a certain extent. At the same time, since the problem that the actual geographical location of the sampling end position can only be realized through simulation is avoided, the accuracy of the first soil sample can be improved to a certain extent.

[0059] In the embodiments of this application, by randomly sampling the target cultivated area to obtain the main crop of the sample, the location of the first distance between the ground surface and the second taproot of the main crop of the sample is determined as the sampling start point location; wherein, the first distance is determined based on the second maximum length of the first lateral root, and the sampling end point location is determined based on the first maximum length, and soil sampling is performed based on the sampling start point location and the sampling end point location to obtain the first soil sample. This can determine the sampling start point location and the sampling end point location corresponding to the randomly sampled main crop of the sample, and finally obtain the first soil sample, which can improve the sampling accuracy of the first soil sample to a certain extent.

[0060] Step 206: Based on the first minimum spacing, the first soil sample is divided into layers to obtain a layered soil sample.

[0061] In the embodiments of this application, the implementation of this step can be referred to the embodiment of step 103, and will not be repeated here.

[0062] Optionally, step 206 may include the following sub-steps: Sub-step 2061: Based on the sampling angle and the first maximum length, determine the effective sample length of the first soil sample.

[0063] In the embodiments of this application, the effective sample length of the first soil sample is determined based on the sampling angle and the first maximum length, and the calculation method is shown in Equation 1 below: (Equation 1) In equation 1 above, Indicates the effective sample length. Indicates the first maximum length. Indicates the sampling angle.

[0064] Sub-step 2062: Based on the first minimum spacing and the effective sample length, the first soil sample is divided into layers to obtain a layered soil sample.

[0065] In the embodiments of this application, the first soil sample is first marked according to the effective sample length. Then, the first soil sample is layered according to the first minimum spacing and the effective sample length to obtain layered soil samples. If the effective sample length is not an integer multiple of the first minimum spacing, then one layered soil sample with a length less than the first minimum spacing and multiple layered soil samples with a length equal to the first minimum spacing can be obtained.

[0066] In the embodiments of this application, the effective sample length of the first soil sample is determined based on the sampling angle and the first maximum length. The first soil sample is then layered based on the first minimum spacing and the effective sample length to obtain layered soil samples. The effective sample length of the first soil sample can be calculated, and the first soil sample can be further layered based on the first minimum spacing and the effective sample length to obtain layered soil samples, which can improve the accuracy of layered soil samples to a certain extent.

[0067] Step 207: Perform component analysis on the layered soil samples to obtain the layered soil geographic information of the target cultivated area.

[0068] In the embodiments of this application, the implementation of this step can be referred to the embodiment of step 104, and will not be repeated here.
