Description

Technical Field

[0001] This invention relates to the field of modular plant environmental process control technology for vertical green walls, and more specifically, to an intelligent control device for the root environment of modular plants suitable for vertical green walls. Background Technology

[0002] In the modular plant maintenance process of vertical green walls, existing solutions usually focus on process control around the stability of the root environment's liquid supply. Common treatment methods are to adjust the liquid supply duration, frequency, and volume of each module based on preset irrigation rhythms, tiered and zoned liquid supply rules, or local humidity feedback, and to make corresponding corrections to the control parameters based on drainage conditions or periodic test results. For example, in a vertical green wall continuously laid on a building facade, planting modules are spliced ​​together longitudinally and laterally. The system needs to operate for a long time without disassembling the modules, without interrupting the landscape, and with limited daily maintenance intervention. At the same time, it is also continuously affected by factors such as gravity infiltration, root growth migration, local substrate compaction, and relatively fixed liquid supply paths. Under these operating conditions, although the overall humidity, liquid supply records, and drainage feedback of some modules are still within the set range, there will still be repeated wilting of local plants, uneven growth of modules in the same layer, and water accumulation on one side of the roots while water loss on the other. Further inspection reveals that the actual location where the supplied liquid seeps in has deviated from the actual location where the roots are concentrated. The liquid preferentially enters non-root areas and stagnates, while the main root areas are not effectively supplied with liquid. The existing control method mainly adjusts based on the overall status of the modules or the predetermined liquid supply path, and cannot identify and correct this situation of misalignment between the liquid supply area and the root area. Therefore, the technical problem to be solved by this application is: how to identify and correct the misalignment between the actual area occupied by plant roots and the actual area reached by the liquid supply under the modular operation conditions of a three-dimensional green wall through process control. Summary of the Invention

[0003] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a modular intelligent control device for the plant root environment suitable for vertical green walls. By determining the root occupancy area and liquid path arrival area formed by the response of each measuring point, and generating a liquid supply correction sequence according to the leading edge position relationship and overlap length of the two, the problem mentioned in the background art is solved.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a modular intelligent control device for plant root environment suitable for vertical green walls, comprising: The status reading module is used to read the readings at fixed intervals along the liquid supply direction of each planting module during the trial liquid supply process, record the wet time and the stabilization time of each measuring point, and generate a response sequence. The directional liquid supply module is used to receive liquid supply position instructions and liquid supply cycle instructions, and perform at least two rounds of equal intermittent liquid supply to the planting module through the corresponding liquid inlet, so that the single liquid supply volume and the interruption time are the same in each round, and generate a trial liquid supply sequence. The occupancy determination module generates a stabilization sort based on the stabilization time of each measuring point in the response sequence corresponding to the test liquid sequence, generates a stabilization difference value based on the position difference between two adjacent stabilization sorts, and determines the measuring point segment with a continuous and unchanged stabilization difference value and a continuous stabilization sort at the front as the root occupancy area. The arrival determination module generates a wet arrival sorting based on the arrival time of each measuring point in the response sequence corresponding to the test liquid sequence, and generates a wet arrival difference value based on the position difference between two adjacent rounds of wet arrival sorting. The measuring point segment with a continuous and unchanged wet arrival difference value and a continuous wet arrival sorting at the front is determined as the liquid path arrival zone. The offset correction module generates a correction sequence for moving the inlet backward when the inlet is positioned forward and a correction sequence for moving the inlet forward when the inlet is positioned backward, based on the positional relationship and overlap length between the leading edge of the root system occupancy area and the liquid path arrival area. When the leading edges overlap and the overlap length is insufficient, a correction sequence for equal-volume intermittent liquid supply is generated. The corresponding correction sequence is then sent to the directional liquid supply module to generate the next round of liquid supply trajectory.

[0005] In a preferred embodiment, the status reading module includes: At the start of each round of test liquid supply, a unified timing point is established for the current planting module. The measurement points arranged along the liquid supply direction are cyclically measured at fixed intervals to generate the original measurement values ​​of each measurement point for each round of test liquid supply. Arrange the original readings of each measuring point in the same round of test liquid supply according to the reading time sequence, and determine the time of the first reading in the first two consecutive increases as the wet time of that measuring point; Arrange the original readings of each measuring point in the order of reading time after the same round of test liquid supply. The first reading time in the first two consecutive unchanged or the subsequent reading value is lower than the previous reading value is determined as the stabilization time of the measuring point. The wet arrival time and stabilization time of each measuring point are written into the corresponding measuring point location according to the measuring point location order, generating the response sequence corresponding to the current planting module.

[0006] In a preferred embodiment, the directional liquid supply module includes: According to the liquid supply cycle command, each round of trial liquid supply is divided into multiple liquid supply segments and stop segments, so that the liquid supply volume of the corresponding liquid supply segment in each round is the same and the stop duration of the corresponding stop segment is the same, thus generating the liquid supply cycle. Select the inlet of the current planting module according to the liquid supply location instruction, and execute the first round of trial liquid supply according to the liquid supply rhythm. Write the order of each liquid supply segment, the liquid supply volume, and the stop time of the corresponding stop segment into the first round of liquid supply record.

[0007] In a preferred embodiment, the directional liquid supply module further includes: After the first round of test supply is completed, keep the inlet unchanged, and write the sequence, supply volume and stop time in the first round of supply record into the second round of test supply to generate the second round of supply record. The first and second rounds of liquid supply records are combined in the order of rounds to generate a test liquid supply sequence, so that the difference between the two rounds of test liquid supply corresponds only to the changes in the liquid path within the current planting module.

[0008] In a preferred embodiment, the occupancy determination module includes: Based on the response sequence corresponding to the test liquid sequence, extract the stabilization time of each measuring point in each round of test liquid supply. Generate the stabilization sort of each round according to the stabilization time of each measuring point. Then generate the stabilization difference value according to the position change of the same measuring point in the stabilization sort of two adjacent rounds. Write the stabilization sort and stabilization difference value corresponding to each measuring point into the position of each measuring point. The determination window is formed by the positions of each measuring point corresponding to three consecutive rounds of test liquid supply. For each measuring point, first check whether the stabilization difference value is continuous and unchanged, then check whether the stabilization order is continuously at the front, and then check whether the stabilization difference values ​​of adjacent measuring points are in the same direction or zero. If all three tests are true, the measuring point is written as a passing measuring point; otherwise, it is written as a blocking measuring point.

[0009] In a preferred embodiment, the occupancy determination module further includes: Adjacent measuring points that pass through the measuring point are merged into candidate segments. For each candidate segment, first check whether the stabilization difference of each measuring point in the segment remains continuous, then check whether the stabilization order of each measuring point in the segment is continuously at the front, and then check whether the adjacent measuring points on both sides of the segment are both blocking measuring points. If all three tests are true, the candidate segment is written as a locked segment. Otherwise, the measuring point that fails the first test is used as the dividing point to decompose the candidate segment into at least two sub-segments and the candidate segment test is re-executed.

[0010] In a preferred embodiment, the occupancy determination module further includes: When only one locked segment exists, that locked segment is designated as the root system occupancy zone. When multiple locked segments exist, the sum of the stabilization ranking of each measuring point within each locked segment is calculated, and the segment length of each locked segment is also calculated. The locked segments are arranged in ascending order according to the sum of the stabilization ranking. When the ranking of the sum of the stabilization ranking is unique, the locked segment with the highest ranking is designated as the root system occupancy zone. When the ranking of the sum of the stabilization ranking is not unique, the locked segments with the same ranking of the sum of the stabilization ranking are arranged in descending order according to their segment lengths. The locked segment with the highest segment length is designated as the root system occupancy zone, and the remaining locked segments are not designated as root system occupancy zones.

[0011] In a preferred embodiment, the arrival determination module includes: Extract the arrival time of each measuring point in each round of test liquid supply according to the response sequence corresponding to the test liquid supply sequence. Generate the arrival time sort of each round according to the order of arrival time of each measuring point. Then generate the arrival difference value according to the position change of the same measuring point in the arrival time sort of two adjacent rounds. Write the arrival time sort and arrival difference value corresponding to each measuring point into the position of each measuring point. Adjacent measuring points that are continuously at the beginning of the wetness ranking and whose wetness difference remains constant are merged into candidate segments. Each candidate segment is then examined to see if the wetness ranking of each measuring point in each round of test liquid supply remains consistent. If it remains consistent, the candidate segment is retained; otherwise, the candidate segment is decomposed into at least two sub-segments using the measuring point where the order of the order changes for the first time as the dividing point. For each candidate segment that has been retained, further examine whether there are any adjacent measuring points on both sides of the segment that are at the beginning of the wetness ranking and have a continuous and constant wetness difference value. If there are no such points, the candidate segment is determined as the liquid path arrival area. If there are such points, the adjacent measuring points are merged into the corresponding candidate segment and the candidate segment examination is performed again.

[0012] In a preferred embodiment, the offset correction module includes: Based on the leading edge position relationship between the root system occupying area and the liquid path arrival area in the direction of liquid supply entry, calculate the number of measuring point intervals between the leading edge position of the liquid path arrival area and the leading edge position of the root system occupying area, generate the leading edge offset, and count the overlap length according to the number of overlapping measuring points in the two sections. When the leading edge offset is positive, the inlet is moved backward according to the measurement point interval corresponding to the leading edge offset, while keeping the supply volume and stop time in the test supply sequence unchanged, to generate a correction sequence for moving the inlet backward. When the leading edge offset is negative, the inlet is moved forward according to the measurement point interval corresponding to the leading edge offset, while keeping the supply volume and stop time in the test supply sequence unchanged, to generate a correction sequence for moving the inlet forward.

[0013] In a preferred embodiment, the offset correction module further includes: When the leading edge offset is zero and the overlap length is less than the number of measuring points in the root system occupying area, the liquid supply volume of one round in the test liquid supply sequence is divided into multiple identical liquid supply segments, and the same stop supply duration as the test liquid supply sequence is written between adjacent liquid supply segments to generate a corrected sequence of equal intermittent liquid supply. When the leading edge offset is zero and the overlap length is equal to the number of measuring points in the root system occupying area, a corrected sequence is generated that keeps the inlet position, liquid supply volume and stop supply duration unchanged. The correction sequence corresponding to the current leading edge offset and overlap length in the correction sequence of the backward liquid inlet, the correction sequence of the forward liquid inlet, or the correction sequence of the equal amount of intermittent liquid supply is sent to the directional liquid supply module to generate the next round of liquid supply trajectory.

[0014] The technical effects and advantages of this invention are as follows: 1. By identifying the root-occupied area and the liquid-reaching area, and generating corresponding correction sequences according to the leading edge position relationship and overlap length, it is possible to make targeted corrections for situations where the liquid supply deviates from the root area, thereby relatively improving the problems of local wilting, local moisture accumulation and liquid supply misalignment. 2. By keeping the inlet, supply volume and stop time consistent in at least two rounds of trial supply, the difference in response between rounds can mainly reflect the changes in the internal liquid circuit of the module, thereby relatively reducing the impact of input condition fluctuations on subsequent judgment results. 3. By converting the stabilization time into stabilization ranking and stabilization difference, and by screening through measuring points, candidate sections and locked sections step by step, continuous section determination results of root system occupation area can be formed, thereby relatively improving the section misidentification caused by single-point determination. 4. By converting the arrival time of moisture into the moisture arrival sequence and the moisture arrival difference, and combining the internal sequence check and boundary check of the section to determine the liquid path arrival area, the actual penetration range of the liquid in the module can be identified, thereby relatively improving the deviation of judging the liquid path position based solely on the overall humidity. 5. By converting the leading edge position relationship into the leading edge offset and the segment overlap into the overlap length, and then correcting the inlet position and the liquid supply cycle respectively, the leading edge misalignment and insufficient coverage can be handled separately, thereby adjusting the next round of liquid supply trajectory towards the root system occupied area. 6. By rewriting the liquid supply volume of one round into multiple identical liquid supply segments and inserting consistent stop-supply durations when the leading edge positions are consistent but the overlap length is insufficient, the liquid coverage range can be expanded without changing the position of the liquid inlet, thereby relatively improving the problem of uneven liquid supply within the root zone.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Refer to the instruction manual appendix Figure 1-3 The present invention provides a modular intelligent control device for the plant root environment suitable for vertical green walls, comprising: The status reading module is used to read the readings at fixed intervals along the liquid supply direction of each planting module during the trial liquid supply process, record the wet time and the stabilization time of each measuring point, and generate a response sequence. In this embodiment, the status reading module is used to provide unified, continuous, and comparable basic data for subsequent wet arrival time determination, stabilization time determination, stabilization sequence generation, and wet arrival sequence generation. Since the input conditions of the same planting module remain consistent in different rounds of liquid supply, the status reading module needs to first unify the timing benchmark, and then collect the original reading values ​​of each measuring point in a fixed order, so that the response process of each measuring point in each round of liquid supply can be compared according to the same time scale. Based on this, the arrival time and stabilization time of each measuring point are extracted from the original measurement values ​​and written into the corresponding positions according to the measuring point location order, forming a response sequence that can be directly called by the subsequent judgment module. This implementation process includes the following steps: First, when the current planting module starts a round of trial liquid supply, the moment when the directional liquid supply module outputs liquid is recorded as the unified timing point for this round of trial liquid supply. The liquid supply direction is determined by the liquid entry path pointing from the selected inlet of the current round into the module. Then, each measuring point deployed along the liquid supply direction is numbered sequentially. After the unified timing point, the status reading module reads each measuring point cyclically at fixed time intervals. Each complete reading of all measuring points in a round constitutes a complete reading, until the end of this round of trial liquid supply and all measuring points have completed the stabilization determination. The original reading values ​​are the reading values ​​that characterize the local wetness state. In one implementation, it is the converted value of the moisture content corresponding to each measuring point. In another implementation, it is the numerical signal obtained by conversion after the output of the humidity-sensitive element. The status reading module writes all the original reading values ​​of each measuring point in this round of trial liquid supply according to the measuring point number and the reading time, forming the set of original reading values ​​of each measuring point for each round of trial liquid supply. Subsequently, the original readings of the same measuring point in the same round of test liquid supply are arranged in ascending order of reading time, and adjacent original readings are compared one by one starting from a unified timing point. When the next original reading after a certain original reading is higher than the original reading, and the next original reading after that continues to be higher than the previous original reading, the first reading time in this three consecutive readings is determined as the wet arrival time of the measuring point. If the above two consecutive increases are not formed at the current comparison position, the comparison position is moved to the next reading time and the search continues until the first reading time that meets the conditions is found. The purpose of this method is to distinguish between short-term fluctuations and continuous wetting changes at the measuring point, so that the wet arrival time corresponds to the actual time when the liquid arrives at the measuring point and begins to form a continuous wetting response, and not to mistakenly write a single shaking reading as the wet arrival time. After determining the wet time, the original readings of the same measuring point after the end of the same round of liquid supply are arranged in ascending order of reading time, and adjacent original readings are compared one by one starting from the first reading time after the end of the liquid supply. When the next original reading after a certain original reading is the same as the original reading, and the next original reading after that is the same as the previous original reading, or when the next original reading after a certain original reading is lower than the original reading, the previous reading time in this comparison is determined as the stabilization time of the measuring point. If the current comparison position still shows a continuous increase, the search continues until a starting position where the value remains unchanged or decreases for the first time is found. Through this process, the stabilization time corresponds to the starting time when the measuring point ends the continuous increase and enters a stable or declining state after the liquid supply ends, thus providing a unified basis for subsequent stabilization sorting and stabilization difference calculation. Furthermore, after obtaining the arrival time and stabilization time of each measuring point, the status reading module writes the arrival time and stabilization time of the corresponding measuring point into the corresponding measuring point position according to the measuring point number order, forming the response sequence of the current planting module under this round of test liquid supply; wherein, each measuring point position corresponds to at least one measuring point number, one arrival time and one stabilization time, and the response sequences in the previous and subsequent rounds of test liquid supply are written in the same measuring point number order to ensure that the calculation objects of subsequent arrival time sorting, stabilization time sorting, arrival time difference and stabilization time difference are consistent; when the current planting module completes multiple rounds of test liquid supply, the status reading module generates the response sequence corresponding to each round of test liquid supply and stores it in the round order for the occupancy determination module and arrival determination module to call directly; Through the above process, the status reading module converts the local wetting and stabilization changes during the test liquid supply process into unified, comparable, and traceable time data. Subsequent modules do not need to reinterpret the original reading values ​​and can directly perform segment determination based on the wetting time, stabilization time, and position of each measuring point. In this embodiment, the liquid supply direction, measuring point numbering order, unified timing point, and fixed reading interval are all kept consistent. Therefore, the response results between different rounds have a direct basis for comparison, which can eliminate the interference of input changes on subsequent determinations. In practical applications: For a planting module with six measuring points arranged sequentially along the liquid supply direction, the start time of the first round of trial liquid supply is recorded as time zero, and the readings are cyclically taken in the order of measuring points one to six. If the original reading value corresponding to measuring point two increases continuously in the 3rd, 4th, and 5th readings, the 3rd reading time is recorded as the wet time of measuring point two. If measuring point two remains unchanged in the 9th and 10th readings after the liquid supply ends, the 9th reading time is recorded as the stabilization time of measuring point two. The status reading module then writes the wet times and stabilization times of measuring points one to six sequentially into the corresponding measuring point positions to form the response sequence corresponding to this round of trial liquid supply, which is used by subsequent modules to continue generating wet sorting, stabilization sorting, and corresponding segment judgment results.

[0020] The directional liquid supply module is used to receive liquid supply position instructions and liquid supply cycle instructions, and perform at least two rounds of equal intermittent liquid supply to the planting module through the corresponding liquid inlet, so that the single liquid supply volume and the interruption time are the same in each round, and generate a trial liquid supply sequence. In this embodiment, the directional liquid supply module is used to establish consistent liquid supply conditions between each round of trial liquid supply, so that the source of difference in the subsequent response sequence is limited to the liquid path propagation process within the current planting module, without being mixed in by changes in the liquid inlet, changes in the liquid supply volume, or changes in the duration of the stop supply. To this end, a common liquid supply rhythm is first formed according to the liquid supply rhythm command for each round of trial liquid supply. Then, the liquid inlet of the current planting module is selected according to the liquid supply position command to execute the first round of trial liquid supply, and the execution content of the first round of trial liquid supply is written into the first round of liquid supply record. Subsequently, while keeping the liquid inlet unchanged, the first round of liquid supply record is copied item by item to the second round of trial liquid supply to generate the second round of liquid supply record. Finally, the first round of liquid supply record and the second round of liquid supply record are combined in the order of rounds to form a trial liquid supply sequence to ensure that the two rounds of trial liquid supply are consistent on the input side. This implementation process includes the following steps: First, the cycle of each test supply is divided according to the supply cycle instruction. Specifically, the total supply volume, number of supply cycles, and downtime given in the supply cycle instruction are read. The total supply volume is divided into multiple supply segments according to the number of supply cycles, ensuring that the supply volume of each supply segment is the same. Then, a downtime segment is inserted between two adjacent supply segments, ensuring that the downtime of each downtime segment is the same. The supply segments and downtime segments are arranged alternately in chronological order. No downtime segment is set before the first supply segment, and no downtime segment is added after the last supply segment, thus forming the supply cycle corresponding to one test supply. In two test supply cycles, the number of supply segments, the supply volume of each supply segment, and the downtime of each downtime segment are kept in a one-to-one correspondence to ensure that the supply volume of the corresponding supply segment is the same and the downtime of the corresponding downtime segment is the same in each cycle. Next, the inlet of the current planting module is selected according to the liquid supply position command, and the first round of trial liquid supply is executed according to the liquid supply rhythm. The specific procedure is as follows: First, the target liquid supply inlet corresponding to the current planting module is determined according to the liquid supply position command. Then, the opening and closing of the target liquid supply inlet is controlled according to the order of each liquid supply segment and stop segment in the liquid supply rhythm. In each liquid supply segment, the directional liquid supply module outputs the corresponding liquid supply volume to the target liquid supply inlet. In each stop segment, the liquid supply is stopped and the corresponding stop duration is maintained. After the first round of trial liquid supply is completed, the order of each liquid supply segment, the liquid supply volume of each liquid supply segment, and the stop duration of the corresponding stop segment after each liquid supply segment are written into the first round of liquid supply record in chronological order. The order is used to identify the position of each liquid supply segment in this round, the liquid supply volume is used to identify the input volume of each liquid supply segment, and the stop duration is used to identify the duration of the corresponding stop segment after each liquid supply segment, thus forming the first round of liquid supply record that can be directly called in the next round. Subsequently, after the first round of test liquid supply, the inlet remains unchanged, and the sequence, supply volume, and stop duration from the first round of supply record are written into the second round of test liquid supply. Specifically, the target inlet selected in the first round of test liquid supply is used without changing the inlet position. Then, the corresponding supply volume is read item by item according to the arrangement of each supply segment in the first round of supply record, and the corresponding stop duration is read after each supply segment. The second round of test liquid supply is executed sequentially. After the execution is completed, the actual execution sequence, supply volume, and stop duration of this round are written into the second round of supply record. Since the second round of test liquid supply directly copies the input content in the first round of supply record and the inlet remains unchanged, the second round of test liquid supply is consistent with the first round of test liquid supply at the input end. The difference in the response of each measuring point can directly correspond to the change in the liquid path propagation within the current planting module. Finally, the first and second rounds of liquid supply records are combined in sequence to generate a test liquid supply sequence. Specifically, the first round of liquid supply records are written to the position of the previous round in the test liquid supply sequence, and the second round of liquid supply records are written to the position of the next round in the test liquid supply sequence. This ensures that the two rounds of test liquid supply form a continuous correspondence under the same planting module, the same inlet, and the same liquid supply cycle. When the subsequent status reading module performs synchronous readings on each measuring point based on this test liquid supply sequence, the different response results between the first and second rounds of test liquid supply are no longer attributed to changes in the liquid supply volume, the duration of the stop supply, or the inlet, but rather to changes in the arrival order of the liquid path, the liquid residence position, and the propagation path within the current planting module. This provides a unified input basis for subsequent wet sorting, stabilization sorting, root occupation zone determination, and liquid path arrival zone determination. Through the above process, the directional liquid supply module first unifies the liquid supply rhythm of each round of trial liquid supply, then fixes the liquid inlet position of the current planting module, and directly copies the liquid supply record of the first round to the second round of trial liquid supply, thereby limiting the input conditions of the two rounds of trial liquid supply to the same set of liquid supply conditions; on this basis, when the response sequences generated by subsequent modules based on the trial liquid supply sequence are compared, the differences can be directly attributed to the changes in the liquid circuit within the current planting module, without mixing in the input differences between rounds. Therefore, the entire trial liquid supply process has clear comparability and executability. In practical applications: When the liquid supply cycle command specifies a total supply volume of 120 ml for a single trial supply, 3 supply cycles, and a 20-second pause, the directional liquid supply module first divides the 120 ml into 3 equal supply segments, supplying 40 ml in each segment. Then, a 20-second pause is inserted between adjacent supply segments to form the liquid supply cycle for the first trial supply. If the liquid supply position command specifies the left inlet of the current planting module as the target inlet, the directional liquid supply module will supply liquid through the left inlet... The liquid inlet sequentially performs a 40 ml supply, a 20-second stop, a 40 ml supply, a 20-second stop, and a 40 ml supply, and records this execution in the first round of liquid supply record. Then, keeping the left inlet unchanged, the same liquid supply sequence, supply volume, and stop duration are executed again according to the first round of liquid supply record to generate the second round of liquid supply record. The first round of liquid supply record and the second round of liquid supply record are then combined in the order of rounds to form a test liquid supply sequence, which is used by the subsequent status reading module to perform corresponding readings on the two rounds of test liquid supply.

[0021] The occupancy determination module generates a stabilization sort based on the stabilization time of each measuring point in the response sequence corresponding to the test liquid sequence, generates a stabilization difference value based on the position difference between two adjacent stabilization sorts, and determines the measuring point segment with a continuous and unchanged stabilization difference value and a continuous stabilization sort at the front as the root occupancy area. The occupancy determination module is used to identify root occupancy areas from the response sequence corresponding to the test liquid supply sequence. Its core is not to directly compare the recovery time of a single measuring point, but to first convert the recovery sequence of each measuring point under each round of test liquid supply into a comparable recovery ranking, then convert the change in the recovery ranking of the same measuring point in two adjacent rounds into a recovery difference value, and then use three consecutive rounds of test liquid supply to form a determination window to check the single measuring point and adjacent measuring point segments step by step, and finally determine the root occupancy area from the locked segment. In this embodiment, the test solution sequence includes at least three consecutive rounds of test solution supply. The third round of test solution supply uses the same inlet, supply volume, and stop duration as the second round of test solution supply to ensure consistency on the input side across the three rounds. This ensures that subsequent judgments only correspond to changes in the liquid path and root occupancy within the current planting module. The implementation process includes the following steps: First, the stabilization time of each measuring point in each round of test liquid supply is extracted based on the response sequence corresponding to the test liquid supply sequence. Then, a stabilization time ranking is generated according to the order of the stabilization times of each measuring point within the same round of test liquid supply. Specifically, in the same round of test liquid supply, the measuring point with the earlier stabilization time is ranked first, and the measuring point with the later stabilization time is ranked last. When two measuring points have the same stabilization time, they are arranged according to the measuring point numbering order along the liquid supply direction, with the measuring point numbered earlier ranked first. After obtaining the stabilization time ranking for each round, the position of the same measuring point in the previous and subsequent rounds of stabilization time ranking is read, and the position in the subsequent round is subtracted from the position in the previous round to obtain the stabilization time difference between the two rounds. Then, the stabilization time ranking and corresponding stabilization time difference of each measuring point in each round of test liquid supply are written to the position of each measuring point, forming a measuring point position record for direct use in subsequent judgments. Subsequently, a judgment window is formed by the positions of each measuring point corresponding to three consecutive rounds of test liquid supply, and three tests are performed on each measuring point in sequence. Among them, the continuous and unchanged stabilization difference means that the stabilization difference of the measuring point between the first and second rounds is equal to the stabilization difference of the measuring point between the second and third rounds. The continuous position of the stabilization ranking means that the position of the measuring point in the stabilization ranking of the three rounds is not greater than the upper limit of the position obtained by dividing the total number of measuring points in the current planting module by two and rounding up. The stabilization difference of adjacent measuring points is in the same direction or is zero, which means that the stabilization difference of the measuring point and the previous or next measuring point are both positive, both negative, or at least one of them is zero. When all three tests of a measuring point are true, the measuring point is written as a passing measuring point; otherwise, it is written as a blocking measuring point. For measuring points located at the beginning or end of the planting module, only the adjacent measuring points on the side where it exists are compared. If there are no adjacent measuring points on that side that meet the conditions, the third test is not true and it is written as a blocking measuring point. Furthermore, adjacent measuring points that are continuously written as passing through the measuring point are merged into candidate segments, and a segment test is performed on each candidate segment. Specifically, the process is as follows: first, check whether the stabilization difference of each measuring point in the judgment window within the candidate segment is continuous and unchanged; then, check whether the position of each measuring point in the same candidate segment in the three rounds of stabilization sorting is continuously at the forefront; and then check whether the measuring point before the first point and the measuring point after the last point of the candidate segment are both written as blocking measuring points. When all three tests are true, the candidate segment is written as a locked segment; when any test is false, the first test is considered false. The measurement point is used as the dividing point. The candidate segment is decomposed into at least two sub-segments located before and after the dividing point. The candidate segment test is then performed again on each sub-segment until all locked segments are obtained or no new candidate segments are found. Among them, the measurement points that fail the first test are determined according to the test order. If the stabilization difference value is discontinuous and unchanged, the measurement point is used as the dividing point. If the stabilization difference value is continuous and unchanged but the stabilization order is not continuously located at the beginning, the measurement point is used as the dividing point. If the first two conditions are met but there are non-blocking measurement points on both sides of the segment, the corresponding boundary measurement point is used as the dividing point. Finally, after the locked segment is determined, the root system occupancy zone is determined. When there is only one locked segment, it is directly determined as the root system occupancy zone. When there are multiple locked segments, the sum of the positions of each measuring point in each locked segment in the three rounds of stabilization sorting is calculated to generate the sum of the stabilization sorting of each locked segment. The number of measuring points contained in each locked segment is also calculated to generate the segment length of each locked segment. Then, the locked segments are arranged in ascending order of the sum of the stabilization sorting. When the position of the sum of the stabilization sorting is unique, the locked segment with the first position is determined as the root system occupancy zone. When the position of the sum of the stabilization sorting is not unique, the locked segments with the same position are arranged in descending order of segment length, and the locked segment with the first position of segment length is determined as the root system occupancy zone. If the position of the sum of the stabilization sorting is the same and the position of the segment length is also the same, the locked segment numbered first along the direction of liquid supply is determined as the root system occupancy zone, and the remaining locked segments are not determined as root system occupancy zones. Through the above process, the occupancy determination module first converts the stabilization time into the stabilization ranking, then converts the inter-row position change into the stabilization difference, and forms a unified determination window with three consecutive rounds of test liquid supply, so that the determination of the root system occupancy area is established on a continuous chain of single measurement point inspection, segment inspection and segment screening; among them, the continuous and unchanged stabilization difference is used to identify the inter-row response stability, the continuous stabilization ranking at the front is used to identify the stabilization leading area, the stabilization difference of adjacent measurement points is in the same direction or is zero, and the adjacent measurement points on both sides of the segment are blocking measurement points to limit the segment boundary; In practical applications: When a planting module has six measuring points along the liquid supply direction, and three consecutive rounds of trial liquid supply are performed through the same inlet, if measuring points two, three, and four consistently rank among the top three in terms of stabilization during the three rounds of trial liquid supply, and the stabilization difference between the first and second rounds for measuring points two, three, and four is the same as the stabilization difference between the second and third rounds, and the stabilization difference between adjacent measuring points is either zero or negative, then measuring points two through four should be prioritized. The fourth section is written as the candidate section by passing through the measurement points and merging them. If each measurement point in the candidate section continuously satisfies the condition that the stabilization difference remains unchanged and the stabilization ranking is continuously at the front, and measurement points one and five are both written as blocking measurement points, then measurement points two to four are written as locked sections. If there is another locked section at the same time, then the sum of the stabilization ranking and the section length of each locked section are compared, and the locked section with the first position of the sum of the stabilization ranking or the first position of the section length under the condition of the same position is determined as the root system occupation area.

[0022] The arrival determination module generates a wet arrival sorting based on the arrival time of each measuring point in the response sequence corresponding to the test liquid sequence, and generates a wet arrival difference value based on the position difference between two adjacent rounds of wet arrival sorting. The measuring point segment with a continuous and unchanged wet arrival difference value and a continuous wet arrival sorting at the front is determined as the liquid path arrival zone. In this embodiment, the arrival determination module is used to identify the liquid path arrival area from the response sequence corresponding to the test liquid supply sequence. Its determination basis is not the single measurement value itself, but the order of arrival of each measuring point in each round of test liquid supply and the change relationship between rounds. To ensure a direct basis for comparison between different rounds, the test supply sequence maintains consistency in inlet, supply volume, and shutdown duration. The arrival determination module first extracts the arrival time of each measuring point from the response sequence, then converts the arrival times into a ranking of arrival times for each round, and further generates the arrival difference value for the same measuring point in adjacent rounds. Based on this, candidate segments that satisfy the condition of continuously ranking at the beginning of the arrival sequence and having a continuously unchanged arrival difference value are first formed. Then, through the consistency of the sequence within the segment and the extensibility test of the segment boundary, the liquid path arrival area is finally determined. This implementation process includes the following steps: First, based on the response sequence corresponding to the test solution sequence, the arrival time of each measuring point in each round of test solution supply is extracted, and the arrival time ranking for that round is generated according to the order of the arrival times of the measuring points within the same round of test solution supply. Specifically, in the same round of test solution supply, the measuring points with earlier arrival times are ranked first, and those with later arrival times are ranked last. When the arrival times of two measuring points are the same, they are arranged according to the measuring point numbering order along the direction of solution supply, with the measuring point numbered earlier ranked first. After obtaining the arrival time ranking for each round, the position of the same measuring point in the arrival time ranking of the previous and subsequent rounds is read, and then... Subtracting the previous round's position from the next round's position generates the moisture difference value for that measuring point between the two rounds. Subsequently, the moisture ranking and corresponding moisture difference value of each measuring point in each round of test solution supply are written to the position of each measuring point, forming a measuring point position record that is directly called in subsequent segment determination. Among them, continuously being at the front of the moisture ranking means that the position of the measuring point in the moisture ranking of each round is not greater than the upper limit of the position obtained by dividing the total number of measuring points in the current planting module by two and rounding up. The continuously unchanged moisture difference value means that the moisture difference value of the measuring point between the first round and the second round is equal to the moisture difference value of the measuring point between the second round and the third round. Next, adjacent measuring points that are continuously ranked at the top in the wetness arrival order and whose wetness arrival difference remains constant are merged into candidate segments. For each candidate segment, the wetness arrival order of each measuring point within that segment is then checked to ensure consistency across all rounds of test liquid supply. Specifically, the positions of each measuring point are scanned along the liquid supply direction. Adjacent measuring points that continuously meet the aforementioned two conditions are designated as the same candidate segment. Then, any two measuring points within that candidate segment are compared pairwise to determine their wetness arrival order across all rounds of test liquid supply. If one measuring point is ranked ahead of another in the first round of wetness arrival order, and this ranking continues in the second and third rounds... If the middle point is still located before the other measurement point, it is determined that the order between the two measurement points is consistent. When all measurement points in the candidate segment are consistent in order with each other, the candidate segment is retained. When the order between a measurement point and its next measurement point in the candidate segment changes in the next round of wet sorting compared to the previous round, the measurement point is written as the dividing point, and the current candidate segment is decomposed into at least two sub-segments located before and after the dividing point, and the candidate segment test is re-executed for each sub-segment until the order is consistent within each retained segment. Subsequently, for each retained candidate segment, further testing is conducted to determine if any of the adjacent measuring points on both sides of the segment have a measurement point that is at the forefront of the wetness ranking and has a continuously unchanged wetness difference value. Specifically, the adjacent measuring points on both sides of the segment are the measuring point preceding the first point and the measuring point following the last point of the candidate segment. If the measuring point preceding the first point does not exist, only the measuring point following the last point is tested; if the measuring point following the last point does not exist, only the measuring point preceding the first point is tested; if neither of the adjacent measuring points on either side exists, the current candidate segment is directly determined to be non-existent and can be merged into a measuring point. Among the adjacent measuring points on both sides, if any measuring point exists that is at the forefront of the wetness ranking and has a continuously unchanged wetness difference value, that measuring point is considered a valid measuring point. The corresponding candidate segment is merged, and the candidate segment test and the test of adjacent measuring points on both sides of the segment are re-executed from the new segment after merging. When there are no measuring points that meet the conditions on both sides, the current candidate segment is determined as the liquid path arrival area. If multiple liquid path arrival areas are formed in the same planting module, the sum of the wetness ranking of each measuring point in each liquid path arrival area is calculated, and the points are arranged in ascending order according to the sum of the wetness ranking. When the position is unique, the liquid path arrival area with the first position is taken as the output segment. When the position is not unique, the liquid path arrival area numbered first along the liquid supply entry direction is taken as the output segment, and the other liquid path arrival areas are not taken as output segments. Through the above process, the arrival determination module transforms the arrival time of each measuring point into arrival order, arrival difference, candidate segment, and liquid path arrival area in sequence, so that the determination of the liquid path arrival area is based on a continuous chain of inter-wheel position change, internal segment order stability, and segment boundary expansion termination condition; among them, arrival order is used to characterize the order of liquid arrival, arrival difference is used to characterize the change of arrival position between wheels, consistency of the order is used to exclude the intersection of propagation relationship within the segment, and the test of adjacent measuring points on both sides of the segment is used to limit the segment boundary; In practical applications: When a planting module has six measuring points along the liquid supply direction, and the liquid supply for three consecutive rounds is input through the same inlet, if measuring points 1, 2, and 3 are all in the top three in terms of wetness in the three rounds of liquid supply, and the wetness difference between the first and second rounds is the same as the wetness difference between the second and third rounds, then measuring points 1 to 3 are first merged into a candidate segment. If the order of measuring points 1 to 3 in the three rounds remains the same (measuring point 1 first, measuring point 2 in the middle, and measuring point 3 last), then the candidate segment is retained. Then measuring point 4 is checked. If measuring point 4 also satisfies the condition of being in the top of the wetness order and having a continuous wetness difference, then measuring point 4 is merged into the candidate segment and re-checked. If the order of measuring points 1 to 4 remains consistent in the three rounds after the re-check, then the expanded candidate segment is determined as the liquid path arrival area, for subsequent offset correction modules to calculate the leading edge position relationship and overlap length with the root system occupation area.

[0023] The offset correction module generates a correction sequence for moving the inlet backward when the inlet is in front of the root system occupancy area and the liquid path arrival area, and generates a correction sequence for moving the inlet forward when the inlet is in the back of the liquid path arrival area, and generates a correction sequence for equal intermittent liquid supply when the inlets overlap and the overlap length is insufficient when the inlets overlap. The module then sends the corresponding correction sequence to the directional liquid supply module to generate the next round of liquid supply trajectory. In this embodiment, the offset correction module is used to continue to solve the offset position and overlap range of the root system occupation area and the liquid path arrival area after they have been determined, and to redo the next round of liquid supply mode accordingly. The processing sequence is as follows: First, the segment position relationship is converted into a directly calculable leading edge offset and overlap length. Then, based on the leading edge offset, it is determined whether to adjust the inlet position. Subsequently, when the leading edge position is consistent but the coverage is insufficient, the liquid supply cycle is rewritten. Finally, the correction sequence corresponding to the current position relationship is sent to the directional liquid supply module, so that the next round of liquid supply trajectory converges towards the root system occupied area. This implementation process includes the following steps: First, each measuring point is numbered sequentially along the liquid supply inlet direction, and the direction of increasing numbers is determined as the liquid supply inlet direction. The measuring point with the smallest number in each section is determined as the leading edge position of that section. Based on this, the leading edge positions of the liquid path arrival area and the root system occupation area are read. The leading edge offset is generated by subtracting the measuring point number of the leading edge position of the liquid path arrival area from the measuring point number of the leading edge position of the root system occupation area. When the result is positive, it indicates that the liquid path arrival area is located in front of the root system occupation area. When the result is negative, it indicates that the liquid path arrival area is located behind the root system occupation area. When the result is zero, it indicates that the leading edge positions of the two are the same. At the same time, the measuring point numbers in the liquid path arrival area and the root system occupation area are compared one by one. The measuring points that fall into both sections are written as overlapping measuring points. Then, the overlap length is counted based on the number of overlapping measuring points. Subsequently, when the leading edge offset is positive, the absolute value of the leading edge offset is determined as the number of measurement point intervals for the inlet to move backward, and the current inlet is moved backward point by point along the liquid supply direction according to this measurement point interval to generate the corrected inlet position; when the leading edge offset is negative, the absolute value of the leading edge offset is determined as the number of measurement point intervals for the inlet to move forward, and the current inlet is moved forward point by point in the opposite direction of the liquid supply direction according to this measurement point interval to generate the corrected inlet position; regardless of whether the backward or forward movement is performed, the liquid supply volume and the stop time in the test liquid supply sequence are directly inherited, without rewriting the liquid supply volume value and the stop time value, only the corrected inlet position is written in the order of the original liquid supply volume and the original stop time, forming the corrected sequence for the backward movement of the inlet and the corrected sequence for the forward movement of the inlet respectively; Furthermore, when the leading edge offset is zero and the overlapping length is less than the number of measuring points in the root system occupying area, the number of measuring points in the root system occupying area is subtracted from the overlapping length and then one is added to generate the number of supply segments. Then, the supply volume of one round in the test supply sequence is divided into multiple identical supply segments according to the number of supply segments, and the stop supply duration consistent with the test supply sequence is written between two adjacent supply segments to form a corrected sequence of equal-volume intermittent supply. When the leading edge offset is zero and the overlapping length is equal to the number of measuring points in the root system occupying area, the current inlet position is kept unchanged, and the supply volume and stop supply duration of one round in the test supply sequence are kept unchanged to form a maintenance correction sequence. Among them, the number of supply segments is at least two. If the result of subtracting the overlapping length from the number of measuring points in the root system occupying area and then adding one is less than two, then the number of supply segments is written as two. Finally, based on the current leading edge offset and the current overlap length, the corresponding correction sequence is selected from the correction sequence for the backward-moving inlet, the correction sequence for the forward-moving inlet, the correction sequence for equal-volume intermittent liquid supply, and the maintenance correction sequence and sent to the directional liquid supply module. Specifically, when the current leading edge offset is positive, the correction sequence for the backward-moving inlet is sent; when the current leading edge offset is negative, the correction sequence for the forward-moving inlet is sent; when the current leading edge offset is zero and the overlap length is less than the number of measuring points in the root system occupying area, the correction sequence for equal-volume intermittent liquid supply is sent; and when the current leading edge offset is zero and the overlap length is equal to the number of measuring points in the root system occupying area, the maintenance correction sequence is sent. After receiving the corresponding correction sequence, the directional liquid supply module generates the next round of liquid supply trajectory according to the corrected inlet position, liquid supply volume, and stop supply duration. Through the above process, the offset correction module first converts the positional relationship between the root system occupying area and the liquid path arrival area into the leading edge offset, then converts the segment overlap into the overlapping length, and corrects the inlet position and the liquid supply cycle respectively, so that the next round of liquid supply trajectory directly corrects the two types of situations: leading edge misalignment or insufficient coverage. In practical applications: When a planting module has six measuring points along the liquid supply direction, with the root system occupying the area covering measuring points three to five and the liquid path reaching the area covering measuring points two to four, the measuring point at the leading edge of the root system occupying the area is numbered three, and the measuring point at the leading edge of the liquid path reaching the area is numbered two. Therefore, the leading edge offset is one, indicating that the liquid path reaching the area is located in front of the root system occupying the area. At this time, the current liquid inlet is moved back one measuring point interval along the liquid supply direction, while keeping the liquid supply volume and stop time of one round in the test liquid supply sequence unchanged, generating a corrected sequence for moving the liquid inlet back; if the root system occupying the area covers measuring points three to five, If the liquid path reaches the area covering measuring points three to four, then the leading edge offset is zero, the overlap length is two, and the number of measuring points in the root system occupying area is three. At this time, subtract two from three and add one to get two, dividing the liquid supply volume of one round into two liquid supply segments, and writing the original stop time between the two liquid supply segments to generate a correction sequence for equal intermittent liquid supply. If the liquid path reaches the area covering measuring points three to five, then the leading edge offset is zero and the overlap length is equal to the number of measuring points in the root system occupying area. The offset correction module generates a maintenance correction sequence, and the directional liquid supply module executes the next round of liquid supply according to the original inlet position, the original liquid supply volume, and the original stop time.

[0024] Working Principle: This solution first performs at least two rounds of trial liquid supply with consistent input conditions on the target planting module in the vertical green wall, ensuring that the inlet position, liquid supply volume, and stop duration are consistent. Then, during the trial liquid supply, the changes at each measuring point are continuously measured at fixed intervals, and the arrival and stabilization times of each measuring point are determined. Based on this, on the one hand, a stabilization ranking and stabilization difference are generated based on the stabilization times of each measuring point to identify the root-occupied area; on the other hand, a wetness ranking and wetness difference are generated based on the arrival times of each measuring point to identify the liquid path arrival area. Then, the leading edge position relationship and overlap length between the root-occupied area and the liquid path arrival area are compared to determine whether the current liquid entry position is too far forward, too far back, or has a consistent leading edge but insufficient coverage. Finally, the inlet position or liquid supply cycle is corrected based on the judgment results to generate the next round of liquid supply trajectory. The core of the entire process control is not simply checking whether a certain measuring point is wet, but continuously judging whether the actual liquid arrival position is consistent with the actual root distribution position, and then gradually adjusting the liquid supply to the position truly needed by the roots. For example, in a vertical green wall on a building facade, the plants in a certain planting module may appear to be growing poorly, but regular irrigation records show that the sap supply is normal. In this case, the solution will first perform two rounds of trial sap supply according to a predetermined rhythm, and then read the responses of multiple measuring points inside the module. If the results show that the liquid always reaches the measuring points at the front first, while the measuring points corresponding to the areas where the roots are actually concentrated stabilize earlier and are located further back, it means that the liquid path reaches the area at the front, and the liquid has not accurately entered the main area occupied by the roots. The system will then adjust the inlet back and supply liquid again. If the leading edge is aligned, but the liquid only covers part of the root area, the system will change the continuous sap supply to multiple intermittent sap supplies of equal volume, allowing the liquid to continue to penetrate backward. In this way, the sap supply method inside the module is not fixed, but is constantly corrected according to the root position and changes in the sap path, so that process control is truly implemented in the root environment itself during actual operation.
