Description

Technical Field

[0001] This application relates to the fields of ecological protection, intelligent operation and maintenance of bio-valleys and soil and water conservation, specifically to a willow pile fracture monitoring and maintenance system and method for bio-valleys. Background Technology

[0002] The stability and survival rate of the willow stumps in the Bio-Valley are the decisive factors in determining the effectiveness of the Bio-Valley in soil and water conservation and ecological restoration. In order to ensure the stability and survival rate of the willow stumps, it is particularly important to test the broken willow stumps, replant the broken willow stumps, and continuously supply water to the willow stumps.

[0003] Existing willow stump breakage detection technologies rely on actively powered sensors, which have poor adaptability and lack precise positioning capabilities, resulting in significant delays in manual inspections. Current willow stump replanting schemes depend on manual experience, lacking standardized guidance for replanting operations. The low degree of matching between replanting specifications and operational details leads to slow root growth and difficulty in guaranteeing survival rates after replanting. Furthermore, in arid and semi-arid regions, uneven rainfall distribution in bio-farms makes willow stump roots prone to necrosis due to water shortage. Existing infiltration and water storage technologies are mostly single-function water collection or supply designs, resulting in low water resource utilization and reduced long-term stability of bio-farms. Therefore, existing technologies suffer from delayed willow stump breakage alarms, inefficient replanting schemes, and insufficient water supply during droughts. Summary of the Invention

[0004] In view of this, this application provides a willow stump fracture monitoring and maintenance system for bio-valleys, the system comprising: a willow stump fracture self-excitation sensing module, a precision rooting and maintenance module, a drought-period synergistic infiltration and water storage module, and a system platform, wherein: The willow stump breakage self-excitation sensing module is used to automatically generate an alarm data packet when a willow stump breaks at the Bio Valley, and push the alarm data packet to the system platform and the mobile terminal carried by the willow stump management personnel; the alarm data packet carries the willow stump number, breakage time, GPS coordinates and the type of sensing unit used to detect the willow stump breakage event; The precision rooting and maintenance module is used to generate and push replanting and maintenance plans for willow stumps to the system platform and the mobile terminals carried by willow stump managers based on the willow stump number, breakage time, GPS coordinates and sensor unit type transmitted through the system platform, as well as the willow stump archive data and real-time data of the willow stump. The drought-period co-infiltration and water storage module is used to perform integrated closed-loop operation of water collection, storage and supply, and provides capillary water supply to the willow root system through capillary water carriers pre-embedded in the root area during drought periods; The output of the willow stump fracture self-excitation sensing module is connected to the input of the system platform; the precision rooting and maintenance module and the drought period collaborative infiltration and water storage module both interact with the system platform.

[0005] Optionally, the willow pile fracture self-excitation sensing module includes a sensing unit for detecting willow pile fracture events, and the types of sensing units include conductivity change sensing units and stress change sensing units. In the case of the willow stakes in Bio Valley being bound willow stakes, the type of sensing unit corresponding to the willow stakes is a conductivity change sensing unit; the conductivity change sensing unit uses a graphite powder bio-based gel conductive circuit integrated inside the binding rope. When the willow stake breaks, the binding rope generates instantaneous tension as the stake breaks, and the graphite powder bio-based gel conductive circuit is simultaneously pulled apart and generates an electrical signal jump. In the case of willow stakes as the core support stakes in Bio Valley, the type of sensing unit corresponding to the willow stakes is a stress change sensing unit; the stress sensing unit includes a mechanical lever and a limit switch fixed by a broken bamboo pin. When the broken bamboo pin breaks, the mechanical lever is released to trigger the limit switch to generate an electrical signal.

[0006] Optionally, the willow stump fracture self-excitation sensing module includes an alarm transmission unit, which generates an alarm data packet based on the willow stump number, fracture time, GPS coordinates and sensing unit type when an electrical signal jump generated by the graphite powder bio-based gel conductive circuit or an electrical signal generated by a limit switch is detected, and pushes the alarm data packet to the system platform and the mobile terminal carried by the willow stump management personnel.

[0007] Optionally, the replanting and maintenance plan includes the specifications of the new stumps to be replanted at the willow stump site, planting parameters, and supplementary maintenance measures. The precise rooting and maintenance module includes: The biodegradable maintenance package is pre-embedded in the base of the willow stump. The biodegradable maintenance package has a multi-layer structure, including an outer biodegradable membrane, a middle water-retaining layer, and an inner slow-release core containing rooting agent and nutrients. The embedded controller contains specification adaptation decision rules, operation adaptation decision rules, and maintenance adaptation decision rules. It is used to automatically match and generate a replanting and maintenance plan that includes the specifications of the new stump, planting parameters, and supplementary maintenance measures based on alarm data packets, real-time data of the willow stumps, willow stump file data, specification adaptation decision rules, operation adaptation decision rules, and maintenance adaptation decision rules.

[0008] Optionally, the system platform maintains a willow stump archive to store structured data for each willow stump, including at least: willow stump number, GPS coordinates, physical specifications, variety, soil type, biodegradable maintenance package installation information, and load-bearing attributes; when an alarm data packet is received, the system platform associates and retrieves the corresponding willow stump archive data based on the willow stump number and GPS coordinates in the alarm data packet, and sends the willow stump archive data to the precision rooting and maintenance module.

[0009] Optionally, the drought-period co-infiltration and water storage module includes: The catchment area and diversion system set up upstream of the Bio-Valley is used to collect surface runoff and guide it to the water-facing side of the Bio-Valley. The infiltration well pipes connected to the diversion system and the underground water storage facilities are used to store rainwater; A capillary water transport carrier laid between the underground water storage facility and the base of the willow stump is used to automatically transport water to the root system of the willow stump when the measured soil volumetric moisture content is less than the soil volumetric moisture content threshold; the capillary water transport carrier is a ceramic tube or a bio-based fiber rope.

[0010] This application provides a method for monitoring and maintaining willow stump fractures in bio-farms. This method is implemented using the willow stump fracture monitoring and maintenance system provided in this application. The method includes: The self-excited sensing module for willow pile breakage continuously monitors the status of the willow pile and automatically generates an alarm data packet when a willow pile breaks at BioValley. The alarm data packet is pushed to the system platform and the mobile terminal carried by the willow pile management personnel. The alarm data packet carries the willow pile number, breakage time, GPS coordinates and the type of sensing unit used to detect the willow pile breakage event. The system platform associates and retrieves the corresponding willow stump file data based on the willow stump number and GPS coordinates, and sends the willow stump file data, willow stump number, fracture time, GPS coordinates and sensor unit type to the precision rooting and maintenance module. The precision rooting and maintenance module generates and pushes a replanting and maintenance plan for the willow stumps to the system platform and the mobile terminal carried by the willow stump managers based on the willow stump number, breakage time, GPS coordinates, and sensor unit type, as well as the willow stump archive data and real-time data of the willow stumps. This allows the willow stump managers to perform replanting and maintenance operations based on the pushed replanting and maintenance plan. During drought periods, the collaborative infiltration and water storage module performs a closed-loop operation integrating water collection, storage, and supply. During drought periods, it provides capillary water supply to the willow root system through capillary water transport carriers pre-embedded in the root zone of the willow stump.

[0011] Optionally, the willow stump archive data includes the soil type, variety, time of burial of the biodegradable maintenance package, distance from surrounding willow stumps, and load-bearing properties of the willow stump; real-time data of the willow stump includes the real-time groundwater level and real-time soil organic matter content; the steps for generating a replanting and maintenance plan for the willow stump include: Based on the load-bearing properties, variety, real-time groundwater level, real-time soil organic matter content, and specification matching decision rules of the willow stumps, determine the variety, diameter, and length of the new stumps to be replanted. Based on the soil type corresponding to the willow stump, the distance between it and the surrounding willow stumps, and the operation adaptation decision rules, determine the planting depth and planting location of the new stump to be replanted. Based on the burial time of the biodegradable maintenance package corresponding to the willow stump, the real-time soil volumetric moisture content, the real-time soil organic matter content, and the maintenance adaptation decision rules, determine the amount of rooting agent to be used for the new stump to be replanted, as well as the number of additional watering packages and biodegradable maintenance packages. Based on the variety, diameter, length, planting depth, and planting location of the new stumps to be replanted, a replanting plan for the willow stumps is generated; and based on the amount of rooting agent to be used for the new stumps, as well as the number of additional watering packs and biodegradable maintenance packs, a maintenance plan for the willow stumps is generated.

[0012] Optionally, the method further includes the step of establishing a willow stump archive: during the construction phase of the bio-valley, a biodegradable maintenance package is pre-embedded for each willow stump, and the specifications, location, and biodegradable maintenance package embedding information of each willow stump are entered into the system platform to establish a willow stump archive.

[0013] Optionally, the drought-period synergistic infiltration and storage module includes a catchment area and diversion system, underground water storage facilities, and a capillary water transport carrier laid between the underground water storage facilities and the roots of the willow stumps. The method also includes the following integrated steps of water collection, storage, and supply: Rainfall runoff is collected through catchment areas and diversion systems and stored in underground water storage facilities; Soil moisture sensor is used to monitor the volumetric water content of soil in the root zone of willow stumps. When the measured volumetric water content is less than the soil volumetric water content threshold, water in the water storage facility is transported to the root zone of willow stumps through capillary water transport carrier. The capillary water transport carrier is a ceramic tube or a bio-based fiber rope.

[0014] The willow stump fracture monitoring and maintenance system provided in this application embodiment for BioValley Farm features a self-excited willow stump fracture sensing module that automatically generates an alarm data packet containing the stump's number, fracture time, GPS coordinates, and sensor unit type when a stump fractures. This alarm data packet is then pushed to the system platform and the mobile terminal carried by the willow stump management personnel, enabling real-time monitoring, precise location, and immediate notification of fracture events, eliminating the lag of traditional manual inspections. The precise rooting and maintenance module, based on the willow stump number, fracture time, GPS coordinates, and sensor unit type transmitted by the system platform, as well as the willow stump archive data and real-time data, can... The system generates refined replanting and maintenance plans, enabling willow stump managers to improve root growth and survival rates after replanting. During droughts, a collaborative infiltration and storage module performs a closed-loop operation integrating water collection, storage, and supply, enhancing water resource utilization and the long-term stability of the bio-valley. Furthermore, during droughts, the module provides capillary water supply to the willow stump roots through pre-embedded capillary water carriers, ensuring the normal growth of existing stumps and providing stable moisture support for newly planted stumps, thus improving the bio-valley's drought resistance. The system also features self-triggered alarms for willow stump breakage, generating refined replanting and maintenance plans based on alarm data packets, ensuring continuous water supply during droughts, and a closed-loop operation integrating water collection, storage, and supply, thereby improving the bio-valley's structural stability, ecological adaptability, and self-sustaining capacity.

[0017] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0018] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments of this application pertain. It should also be understood that terms such as those defined in general dictionaries should be understood to have a meaning consistent with their meaning in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0019] This application provides a willow stump fracture monitoring and maintenance system for bio-valley workshops, such as Figure 1 The diagram shows a structural schematic of a willow stump fracture monitoring and maintenance system for a bio-valley, as provided in this application. The system 100 includes: a willow stump fracture self-excitation sensing module 101, a precision rooting and maintenance module 102, a drought-period synergistic infiltration and water storage module 103, and a system platform 104. The output of the willow stump fracture self-excitation sensing module 101 is connected to the input of the system platform 104; both the precision rooting and maintenance module 102 and the drought-period synergistic infiltration and water storage module 103 interact with the system platform 104. The system platform 104 can be a cloud monitoring platform, an edge device monitoring platform, or a local device monitoring platform.

[0020] In some embodiments, the willow stake breakage self-excitation sensing module 101 is used to automatically generate an alarm data packet when the willow stake in the bio-valley breaks, and push the alarm data packet to the system platform 104 and the mobile terminal carried by the willow stake management personnel.

[0021] The alarm data packet includes the willow stake number, breakage time, GPS coordinates, and the type of sensor unit used to detect the willow stake breakage event.

[0022] In some embodiments, the core support willow stakes serve as the "skeleton" or "pillar" of the bio-valley, directly resisting the impact of water flow and the pressure of soil and rocks, maintaining the overall structural mechanical stability. They are typically made of thicker, more durable logs with larger diameters and deeper penetration into the soil, and are usually placed at key stress points of the bio-valley, such as the bottom, corners, and water impact surfaces. Bundled willow stakes are mainly used for filling and fixing stones and soil, promoting vegetation growth, assisting in energy dissipation, and preventing localized soil erosion. They utilize relatively uniform and low-cost willow stakes or other easily rooting branches, and are typically placed in large numbers in rows or densely in a network along the slopes and ditches of the entire bio-valley. The reliability of fracture monitoring for core support willow stakes is generally higher than that for bundled willow stakes.

[0023] In some embodiments, such as Figure 2 As shown, the willow pile fracture self-excitation sensing module 101 includes sensing units for detecting willow pile fracture events. The types of sensing units include conductivity change sensing unit 1011 and stress change sensing unit 1012.

[0024] In some embodiments, when the willow stakes in the Bio Valley are bound willow stakes, the type of sensing unit corresponding to the willow stake is a conductivity change sensing unit 1011; the conductivity change sensing unit 1011 adopts a graphite powder bio-based gel conductive circuit integrated inside the binding rope. When the willow stake breaks, the binding rope generates instantaneous tension as the stake breaks, and the graphite powder bio-based gel conductive circuit is simultaneously pulled apart and generates an electrical signal jump.

[0025] In some embodiments, the binding rope used for collecting data from the bundled willow stakes is a plant fiber rope, which serves as a natural carrier. An axially woven conductive circuit is formed within the fiber rope. The conductor within the conductive circuit is a polylactic acid-based biogel containing 20%–30% graphite powder, molded into a 1.2 mm diameter filament structure, and wrapped with a 0.3 mm thick flax fiber protective layer. The volume resistivity of the conductive gel is controlled at 50–80 Ω•cm to ensure conductive stability. By adjusting the graphite powder content and the degree of gel cross-linking, the breaking strength of the conductive circuit is precisely set to 60%–70% of the main fiber rope strength, forming a mechanical hierarchy of main load-bearing and circuit sensing, ensuring that the circuit breaks first to trigger the signal when the willow stake breaks. When the willow stake breaks due to flood impact, rockfall, or natural aging, the binding rope generates instantaneous tension as the willow stake breaks, and the conductive circuit is simultaneously pulled apart, forming a self-excited signal of power interruption upon breakage (the electrical signal transitions from high to low level). No external power supply is required to maintain the sensing state, and the trigger response time is ≤5 ms.

[0026] It should be noted that since the polylactic acid-based biogel of graphite powder is directly integrated into the binding rope, it adds almost no additional material and installation costs, making it suitable for large-scale applications and reducing the cost of fracture monitoring for binding willow stakes.

[0027] In some embodiments, when the willow stakes of the Bio Valley are the core support willow stakes, the type of sensing unit corresponding to the willow stakes is a stress change sensing unit 1012; the stress change sensing unit 1012 includes a mechanical lever fixed by a breakable bamboo pin and a limit switch, and when the breakable bamboo pin breaks, the mechanical lever is released to trigger the limit switch to generate an electrical signal.

[0028] In some embodiments, the mechanical lever is an L-shaped lightweight bamboo lever. To meet the high-sensitivity monitoring requirements of the willow piles supporting the core of the Bio-Valley, an L-shaped lightweight bamboo lever (e.g., 35cm long, 4cm wide, and 1.5cm thick) is installed at the base of the willow pile, 8-12cm above the ground. The lever fulcrum uses a nylon bearing, and the trigger end is fixed to a pre-set wooden support on the willow pile using a 5mm diameter easily broken bamboo pin. The free end is tightly fitted to an IP68-rated waterproof travel switch, with the trigger pressure set to 0.8N. The easily broken bamboo pin undergoes high-temperature carbonization treatment, and its shear strength is precisely controlled to 80% of the willow pile's ultimate breaking impact force by controlling the carbonization time, ensuring that the bamboo pin breaks first when the pile breaks, without damaging the lever. The impact force released at the moment the willow pile breaks acts on the fixed end of the lever, causing the easily broken bamboo pin to shear and break. Under its own elastic restoring force, the lever rotates around the fulcrum, and the free end presses down on the internal contacts of the travel switch, changing from open to closed, generating an on / off signal (the electrical signal changes from zero to on, from low level to high level), achieving a zero-delay conversion from mechanical force to electrical signal.

[0029] It should be noted that the shear strength of the easily broken bamboo pin is set to 80% of the ultimate breaking impact force of the willow stake, so that the limit switch can issue an early warning before the willow stake is about to completely break, achieving highly reliable breakage monitoring.

[0030] In some embodiments of this application, the willow pile fracture self-excitation sensing module 101 includes an alarm transmission unit 1013, which is used to generate an alarm data packet based on the willow pile number, fracture time, GPS coordinates and sensing unit type when an electrical signal jump generated by the graphite powder bio-based gel conductive circuit or an electrical signal generated by a limit switch is detected, and pushes the alarm data packet to the system platform 104 and the mobile terminal carried by the willow pile management personnel.

[0031] In some embodiments, when the circuit is broken, the circuit resistance of the alarm transmission unit 1013 connected to both ends of the graphite powder bio-based gel conductive circuit instantly changes from a low resistance of 50~80Ω•cm to a high resistance approaching infinity, and the monitoring current changes from present to absent. After the alarm transmission unit 1013 detects the signal jump (from high level to low level), it generates an alarm data packet based on the willow stake number, breakage time, GPS coordinates and sensor unit type, and pushes the alarm data packet to the system platform 104 and the mobile terminal carried by the willow stake management personnel.

[0032] In some embodiments, the two terminals of the limit switch are connected to the switch signal interface of the alarm transmission unit 1013. When the lever springs up after the bamboo dowel breaks, the internal contacts of the switch change from open to closed, and the level of the switch signal interface changes from low to high, generating an electrical signal. After the alarm transmission unit 1013 detects the electrical signal, it generates an alarm data packet based on the willow stake number, breakage time, GPS coordinates, and sensor type, and pushes the alarm data packet to the system platform 104 and the mobile terminal carried by the willow stake management personnel.

[0033] In some embodiments, the alarm transmission unit 1013 includes a power supply unit and a communication subunit. The power supply unit is equipped with a 5-10W monocrystalline silicon solar panel and a 12V / 5Ah lithium iron phosphate battery, and has overcharge and over-discharge protection functions. The communication subunit adopts an ultra-low power LoRa communication module. When the conductive circuit is broken or the physical switch is triggered, the LoRa communication module immediately wakes up from the standby state to complete signal encoding and transmission, generating an alarm data packet containing the willow stake number (12-bit code, including partition and location information), break time, GPS coordinates (positioning accuracy ±3m), and sensor unit type, and simultaneously pushes it to the system platform 104 and the mobile terminal (such as mobile phone, laptop, tablet, etc.) of the willow stake management personnel, realizing dual reminders of pop-up window and voice through the mobile terminal APP.

[0034] In some embodiments, the precision rooting and maintenance module 102 is used to generate and push a replanting and maintenance plan for willow stumps to the system platform 104 and the mobile terminal carried by the willow stump management personnel based on the willow stump number, fracture time, GPS coordinates and sensor unit type transmitted through the system platform 104, as well as the willow stump archive data and real-time data of the willow stumps.

[0035] In some embodiments, the replanting and maintenance plan includes the specifications of the new stumps to be replanted at the willow stump location, planting parameters, and supplementary maintenance measures, such as... Figure 3 As shown, the precision rooting and maintenance module 102 includes: a biodegradable maintenance package 1021 pre-embedded in the root of the willow stump and an embedded controller 1022.

[0036] In some embodiments, the biodegradable maintenance package 1021 has a multi-layered structure, including an outer biodegradable membrane, a middle water-retaining layer, and an inner slow-release core containing rooting agents and nutrients. The biodegradable maintenance package 1021 is a semi-permeable starch film biodegradable maintenance package, which can lay a good foundation for root growth. The installation of the biodegradable maintenance package 1021 is carried out simultaneously with the main construction of the grain storage area; pre-embedding work is carried out immediately after the willow stumps are planted to avoid damage to the grain storage structure during later excavation. The pre-embedding method of the biodegradable maintenance package 1021 includes: excavating a circular trench with a radius of 60-80 cm and a depth of 40-50 cm centered on a single willow stump, the range of which matches the main distribution area of ​​the willow root system during its germination period. The system employs a three-layer composite structure: an outer 0.4mm thick starch-polyvinyl alcohol blend film, a middle sodium polyacrylate water-retaining layer, and an inner slow-release nutrient core containing 0.6% naphthaleneacetic acid rooting agent, NPK=3:1:2 compound fertilizer, and trace elements boron and zinc. Each package weighs 1.2kg, and three biodegradable maintenance packages are evenly distributed per willow stump. The biodegradable maintenance packages are buried 30-40cm underground, 15-20cm horizontally from the base of the willow stump, and covered with 10cm of humus soil to ensure full contact between the biodegradable maintenance package 1021 and the soil and avoid early exposure. The pre-buried status data of the biodegradable maintenance package 1021 (such as the burial time and quantity) is pre-stored in the system's willow stump archive, providing a reference for the positioning and dosage of biodegradable maintenance packages in determining subsequent maintenance plans.

[0037] In some embodiments, the embedded controller 1022 has embedded specification adaptation decision rules, operation adaptation decision rules and maintenance adaptation decision rules, which are used to automatically match and generate a replanting and maintenance plan that includes new stump specifications, planting parameters and supplementary maintenance measures based on alarm data packets, real-time data of willow stumps, willow stump file data, specification adaptation decision rules, operation adaptation decision rules and maintenance adaptation decision rules.

[0038] The real-time data can include groundwater level, soil organic matter content, and soil volumetric moisture content in the area to be replanted with willow stumps. Groundwater level can be obtained using a pressure-type water level sensor, soil organic matter content can be determined using a portable soil analyzer based on near-infrared spectroscopy or conductivity-optics principles, and soil volumetric moisture content can be obtained using a humidity sensor. Willow stump profile data includes: the load-bearing properties of the broken willow stump (core support stump or bundled willow stump), variety, distance between the broken willow stump and surrounding willow stumps and biodegradable maintenance packages, soil type at the location of the broken willow stump, production date of the corresponding biodegradable maintenance package 1021, and the concentration and volume of liquid rooting agent within the biodegradable maintenance package.

[0039] In some embodiments, the embedded controller 1022 can determine the location of the willow stump to be replanted based on the willow stump number and GPS coordinates carried in the alarm data packet, thereby controlling the pressure water level sensor to collect the groundwater level at the location, controlling the portable soil analyzer to determine the soil organic matter content at the location, and controlling the humidity sensor to collect the soil volumetric moisture content at the location.

[0040] In some embodiments, the specification adaptation decision rules can determine the diameter, length, and variety of the new stake to be replanted. As shown in Table 1, the specification adaptation decision rules include: diameter matching: the diameter of the new stake to be replanted corresponding to the core support stake is 1 cm larger than the original stake to ensure that the load-bearing capacity does not decrease; the diameter of the new stake to be replanted corresponding to the ordinary protective stake has an error of ≤0.5 cm with the original stake to avoid affecting the fit of the grid structure; length matching: if the groundwater level is high (≥0.3m and ≤1m), the length of the replanted stake is 0.1m shorter than the original stake to prevent the roots from being flooded; if the soil fertility is low (organic matter content <1%), the length of the replanted stake is 0.1m longer than the original stake to ensure that the roots can contact deep nutrients; variety matching: strictly match the variety of the original stake to avoid a decrease in survival rate due to differences in the rooting characteristics of the varieties.

[0041] Table 1. Schematic diagram of specification adaptation decision rules In some embodiments, the operational adaptation decision rule can determine the planting depth of the willow stump to be replanted, the distance between the biodegradable maintenance package and the willow stump to be replanted, and the distance between the willow stump to be replanted and the surrounding willow stumps, etc. As shown in Table 2, the operational adaptation decision rules include: planting depth matching: in low-permeability clay soil areas (including clay, clay loam, sandy clay, silt, etc., mainly composed of clay particles and with weak permeability), the planting depth of the willow stumps to be replanted is 0.05m shallower than the original stumps, and a drainage measure of laying a 5cm layer of gravel at the bottom of the planting hole is matched; in high-permeability sandy loam soil areas (including sandy loam, loam, etc., mainly composed of sand particles and with strong permeability), the planting depth of the willow stumps to be replanted is the same as the original stumps, and a water retention measure of watering 200mL of water after planting is matched; planting location matching: the distance between the willow stumps to be replanted and the biodegradable maintenance package (corresponding to biodegradable maintenance package 1021) is 15~20cm, to ensure that the roots of the new stumps can quickly absorb the rooting agent and nutrients in the biodegradable maintenance package; planting spacing matching: based on the distribution coordinates of the willow stumps around the archive, the spacing between the new stumps to be replanted and the surrounding stumps is automatically matched to be ≥0.8m, to avoid affecting the sand retention and diversion functions of the valley.

[0042] Table 2. Schematic diagram of operation adaptation decision rules In some embodiments, the maintenance adaptation decision rule can determine the dosage of liquid rooting agent (naphthaleneacetic acid volume) in the corresponding biodegradable maintenance package for the willow stump to be replanted, and whether it is necessary to add a water-retaining package and a biodegradable maintenance package (slow-release compound fertilizer package), as shown in Table 3. The maintenance adaptation decision rule includes: matching the dosage of rooting agent; if the remaining shelf life of the biodegradable maintenance package is >60 days, match 50 mL of 100 mg / L liquid rooting agent for mild activation to avoid inhibition; if the remaining shelf life of the biodegradable maintenance package is >60 days, match 50 mL of 100 mg / L liquid rooting agent for mild activation to avoid inhibition; if the remaining shelf life of the biodegradable maintenance package is >60 days, match 50 mL of 100 mg / L liquid rooting agent for mild activation to avoid inhibition. If the remaining shelf life is less than 30 days, supplement with 100mL of 120mg / L liquid rooting agent to enhance stimulation and compensate for slow-release failure. Additional measures include: if the soil volumetric moisture content is less than 15% (drought period), supplement with a 100g water-retaining pack to extend the water buffer period; if the soil organic matter content is less than 1% (low soil fertility), supplement with a 50g slow-release biodegradable maintenance pack (compound fertilizer pack, including N, P, K and trace elements, etc.) to ensure rapid root germination and seedling survival of new stumps.

[0043] It should be noted that the remaining shelf life of the biodegradable maintenance pack can be determined based on the production date of the biodegradable maintenance pack recorded in the willow stump archive data, as well as the current date. Furthermore, biodegradable maintenance packs with a shelf life of 30-60 days still retain some nutrient reserves. There is no need to increase the concentration (100 mg / L is the basic effective concentration). Simply increasing the dosage can compensate for nutrient depletion, ensuring root-promoting effects while avoiding premature use of high concentrations (120 mg / L) that could lead to root malformation.

[0044] Table 3. Schematic diagram of maintenance adaptation decision rules In some embodiments, after generating a replanting and maintenance plan that includes the specifications of the new stump, planting parameters, and supplementary maintenance measures, the precision rooting and maintenance module 102 can simultaneously push the alarm data packet and the replanting and maintenance plan that includes the specifications of the new stump, planting parameters, and supplementary maintenance measures to the mobile terminal of the willow stump manager, or push it to the mobile terminal of the willow stump manager through the system platform 104. After receiving the information, the willow stump manager can navigate directly to the location of the broken willow stump according to the GPS coordinates carried in the alarm information packet, verify the identity information of the willow stump by combining the willow stump number carried in the alarm information packet, and operate according to the replanting and maintenance plan that includes the specifications of the new stump, planting parameters, and supplementary maintenance measures. Insert the new stumps to be replanted into the original position, ensuring that the planting depth meets the requirements of the plan; apply liquid rooting agent 10-15cm away from the pre-buried biodegradable maintenance package using a syringe or small dropper; simultaneously check the status of biodegradable maintenance packages of unbroken willow stumps within 3m of the broken stump, and if exposed or damaged biodegradable maintenance packages are found, cover them with soil or add new biodegradable maintenance packages in time to ensure the root growth stability of the overall willow stump group.

[0045] In some embodiments, after the willow stump manager has completed the replanting and maintenance operations, he can send the results data of the planting and maintenance to the system platform 104 (including the distance between the replanted willow stump and the biodegradable maintenance package, the production date and quantity of the biodegradable maintenance package, the volume and concentration of the liquid rooting agent, etc.). The system platform 104 can update the data in the willow stump archive based on the results data.

[0046] Understandably, based on alarm data packets, real-time data of willow stumps, willow stump archive data, specification adaptation decision rules, operation adaptation decision rules, and maintenance adaptation decision rules, a refined replanting and maintenance plan is automatically matched and generated, which includes the specifications of the new stumps, planting parameters, and supplementary maintenance measures. This solves the problem of the extensive nature of existing replanting and maintenance plans, and improves the survival rate and growth rate of replanted willow stumps after operation based on the replanting and maintenance plan that includes the specifications of the new stumps, planting parameters, and supplementary maintenance measures.

[0047] In some embodiments of this application, the system platform 104 maintains a willow stump archive to store structured data for each willow stump, including at least: willow stump number, GPS coordinates, physical specifications, variety, soil type, biodegradable maintenance package installation information, and load-bearing properties. This structured data is acquired during the willow stump pre-installation stage. The physical specifications include the diameter and length of the willow stump; the biodegradable maintenance package installation information includes the distance between the biodegradable maintenance package and the center of the willow stump, the production date of the biodegradable maintenance package, the installation date, and the concentration and volume of the liquid rooting agent inside the biodegradable maintenance package.

[0048] In some embodiments, after receiving an alarm data packet, the system platform 104 performs dual verification based on the willow stump code and GPS coordinates in the alarm data packet. That is, it compares the willow stump code in the alarm data packet with the willow stump codes pre-stored in the willow stump archive, and compares the GPS coordinates in the alarm data packet with the willow stump GPS coordinates pre-stored in the willow stump archive to ensure that the matched willow stump number and GPS coordinates correspond to the same willow stump. This allows the system to associate and call the corresponding willow stump archive data, which includes the original stump diameter, length, planting depth, soil type, burial time, etc., and send the willow stump archive data to the precision rooting and maintenance module 102. Subsequently, the embedded controller 1022 in the precision rooting and maintenance module 102 can generate a suitable replanting and maintenance plan based on the willow stump archive data, alarm data packet, real-time data of the willow stump, specification adaptation decision rules, operation adaptation decision rules, and maintenance adaptation decision rules. In addition, the system platform 104 can also filter out data in the willow stump archive that is irrelevant to replanting, such as information on willow stump purchasers, construction personnel, and transportation records, and retain only the key data for replanting, forming a concise subset of replanting demand data.

[0049] Understandably, the system platform 104 stores structured data for each willow stump, which facilitates the maintenance and management of information on each willow stump in the Bio Valley, ensuring the authenticity and reliability of the information on each willow stump.

[0050] In some embodiments of this application, the drought-period co-infiltration and water storage module 103 is used to perform integrated closed-loop operation of water collection, storage and supply, and to provide capillary water supply to the willow root system through capillary water transport carriers pre-embedded in the root zone of the willow stump during drought periods.

[0051] In some embodiments, such as Figure 4 As shown, the drought-period co-infiltration and water storage module 103 includes: a water collection area and diversion system 1031 set up upstream of the bio-valley, used to collect surface runoff and guide the surface runoff to the water-facing side of the bio-valley; an infiltration well pipe and underground water storage facility 1032 connected to the diversion system, used to store rainwater; and a capillary water transport carrier 1033 laid between the underground water storage facility and the roots of the willow stumps, used to automatically transport water to the roots of the willow stumps when the measured soil volumetric moisture content is less than the soil volumetric moisture content threshold.

[0052] In some embodiments, the catchment area is constructed on the upstream slope of the valley, with an area of ​​5-10m². 2 The catchment area is spaced 10-15m apart to ensure coverage of the main runoff area on the upstream slope. Compacted clay or biodegradable PE membrane is used as the catchment layer, with a smooth and crack-free surface. The diversion system includes diversion trenches and geotextile. During the construction of the bio-valve, V-shaped diversion trenches are excavated at the edge of the catchment area, and geotextile is laid inside the trenches to prevent soil erosion. During rainfall, the runoff is directed to the upstream side of the valve.

[0053] In some embodiments, 2-3 vertical infiltration pipes are installed every 5m on the water-facing side of the bio-valve. The pipes have evenly spaced 10mm diameter permeable holes, and the perimeter is filled with graded crushed stone to form permeable channels and prevent soil blockage. Rainwater flows in through a diversion ditch and then rapidly infiltrates into the ground through the infiltration pipes. The bottom of the infiltration pipes is connected to a horizontal drainage blind pipe via a tee joint. The blind pipe is laid with a slope of 1%-2% to ensure smooth water flow. The blind pipe is wrapped with geotextile to filter soil particles. A 5-10m³ volume drainage pipe is installed 1-1.5m underground inside the main body of the valve or on its downstream side. 3 The miniature underground water storage facility has an inner wall lined with 50mm thick compacted clay or laid with a biodegradable impermeable membrane, and an inspection port and ventilation holes are set at the top to prevent the stored water from deteriorating.

[0054] In some embodiments, the capillary water transport carrier 1033 is a ceramic tube or a bio-based fiber rope. The ceramic tube is used for main water transport, with an inner diameter of 20 mm and a length of 50-80 cm. The high porosity of the ceramic material facilitates capillary action. The bio-based fiber rope is used for auxiliary water transport, with a diameter of 5 mm. It is made of hemp fiber and water-absorbing resin composite, with a water absorption ratio of 300 times, good flexibility, and adaptability to complex root distribution. During installation, one end of the ceramic tube or bio-based fiber rope is inserted into the water storage facility to a depth of 20 cm to ensure contact with the water level. The other end is buried in the area 20-30 cm deep at the base of the willow stump. This depth corresponds to the dense area of ​​willow fibrous roots. The spacing between adjacent water transport carriers is 50 cm to ensure that the root system of each willow stump covers at least 2-3 water transport points.

[0055] In some embodiments, the volumetric moisture content of the soil at the location of the willow stump can be detected in real time using a soil moisture sensor. When the soil volumetric moisture content is below 15% (the soil volumetric moisture content threshold), it is in a dry period. Water in the water storage facility slowly seeps out through the pores of the ceramic tube or the internal channels of the fiber rope under capillary action, permeating into the soil around the roots. The daily water supply is approximately 0.5~1L / tree. This water supply is determined based on the daily average transpiration water consumption model of willows during the dry period. After 6 months of verification in the Loess Plateau experimental area, 0.7±0.2L / tree / day can maintain the soil moisture content in the root zone >15%. This water supply matches the minimum water requirement of the willow root system during the dry period, meeting the growth needs while avoiding water waste. The continuous water supply cycle can cover 15~20 days of no rainfall, ensuring that the willow stump does not lack water.

[0056] It should be noted that the drought-period collaborative infiltration and water storage module 103 is a routine basic support and is a parallel daily operation unit to the willow pile fracture self-excitation sensor module 101 (both work continuously after pre-installation). It is not a maintenance step after an alarm. The drought-period collaborative infiltration and water storage module 103 can realize water collection, water storage and water supply throughout the entire system process.

[0057] The willow stump fracture monitoring and maintenance system provided in this application embodiment for BioValley Farm features a self-excited willow stump fracture sensing module that automatically generates an alarm data packet containing the stump's number, fracture time, GPS coordinates, and sensor unit type when a stump fractures. This alarm data packet is then pushed to the system platform and the mobile terminal carried by the willow stump management personnel, enabling real-time monitoring, precise location, and immediate notification of fracture events, eliminating the lag of traditional manual inspections. The precise rooting and maintenance module, based on the willow stump number, fracture time, GPS coordinates, and sensor unit type transmitted by the system platform, as well as the willow stump archive data and real-time data, can... The system generates refined replanting and maintenance plans, enabling willow stump managers to improve root growth and survival rates after replanting. During droughts, a collaborative infiltration and storage module performs a closed-loop operation integrating water collection, storage, and supply, enhancing water resource utilization and the long-term stability of the bio-valley. Furthermore, during droughts, the module provides capillary water supply to the willow stump roots through pre-embedded capillary water carriers, ensuring the normal growth of existing stumps and providing stable moisture support for newly planted stumps, thus improving the bio-valley's drought resistance. The system also features self-triggered alarms for willow stump breakage, generating refined replanting and maintenance plans based on alarm data packets, ensuring continuous water supply during droughts, and a closed-loop operation integrating water collection, storage, and supply, thereby improving the bio-valley's structural stability, ecological adaptability, and self-sustaining capacity.

[0058] The following is a comparative experiment illustrating the results of the comparison between the willow stump fracture monitoring and maintenance system provided in this application for bio-valley and the traditional manual inspection mode in terms of early warning efficiency and accuracy, replanting survival rate, drought protection capability, ecological and low-carbon benefits, operation and maintenance costs and efficiency, and structural stability.

[0059] Experimental setup: Select the same biota (area ≥ 500m²) 2 Two parallel experimental areas were divided (with identical soil type, groundwater level, grain structure, and willow species / specifications), with 35 willow stumps in each group.

[0060] Group design: Control group (traditional manual inspection mode): The conventional management of manual inspection, experience-based replanting, and flood irrigation was adopted. Manual inspection was carried out once every 24 hours. When the willow stump broke, the replanting stump was selected based on experience (no database / algorithm support). Watering was carried out using traditional flood irrigation (5L / plant per application, once every 3 days during the dry period).

[0061] Experimental group (the willow stump fracture monitoring and maintenance system provided in this application for Biovalley): deployed with dual-mode sensing, archive algorithm replanting, and capillary water supply system, with other environmental conditions completely consistent with the control group.

[0062] Experimental period: 12 months (covering the entire growing season + 1 drought period to ensure data validity).

[0063] Controlled variables: The initial health status of the willow stumps, planting density, construction techniques, and daily external disturbances (such as floods and rockfalls) were kept consistent, with the only difference being the management mode.

[0064] The detection methods and index calculation methods for each beneficial effect are shown in Table 4 below: Table 4. Schematic diagram of detection methods and index calculation methods for different beneficial effects. Based on the experiment, we found that: 1. The control group took an average of 24 hours to detect the breakage of willow stakes through manual inspection, while the experimental group responded in only 30 seconds. The response speed of the experimental group was 2880 times faster than that of the control group, and the alarm information delivery rate was ≥99%, which solved the problem of delayed detection of willow stake breakage in the existing technology.

[0065] 2. The survival rate of artificial replanting in the control group was 65%, while that in the experimental group was 92%. The survival rate of replanting in the experimental group was 27 percentage points higher than that in the control group, and the seedling recovery period was shortened from 45 days to 25 days.

[0066] 3. Under conditions of no rainfall for 20 consecutive days, the control group consumed 875L of water and had a survival rate of 60% through flood irrigation, while the experimental group consumed only 175L of water through capillary irrigation and had a survival rate of 94%. The water resource utilization rate of the experimental group was 80% higher than that of the control group.

[0067] 4. The physicochemical carbon emissions (carbon emissions from the entire process of system materials, construction, disposal, and degradation) of the control group willow stump system were 14 kg / tree, while the physicochemical carbon emissions of the experimental group were only 1.2 kg / tree, representing a 91.4% reduction in physicochemical carbon emissions compared to the control group. The annual carbon sequestration of living willow stumps in the control group was 2.1 kg / tree, while that in the experimental group was 2.8 kg / tree, representing a 33.3% increase in annual carbon sequestration of living willow stumps in the experimental group compared to the control group.

[0068] 5. The total maintenance cost of the control group was 17,500 yuan over 12 months, while that of the experimental group was 7,000 yuan. The maintenance cost of the experimental group was 60% lower than that of the control group. The time taken for replanting a single plant was 120 minutes in the control group and 40 minutes in the experimental group. The maintenance efficiency of the experimental group was 3 times higher than that of the control group.

[0069] 6. The average standard deviation of the inclination of the willow piles in the control group was 8.5° and the fracture recurrence rate was 12%, while those in the experimental group were 5.1° and 2.9%, respectively. The structural stability of the grain sheds in the experimental group was 40% higher than that in the control group, and the service life of the project was extended from 10 years to 16 years.

[0070] As demonstrated by the above experiments, the willow stump fracture monitoring and maintenance system provided in this application for use in Bio Valley has significant advantages over the traditional manual inspection mode in terms of early warning efficiency and accuracy, replanting survival rate, drought protection capability, ecological and low-carbon benefits, operation and maintenance cost, operation and maintenance efficiency and structural stability.

[0071] This application provides a method for monitoring and maintaining willow stump fractures in bio-farms. This method is based on the willow stump fracture monitoring and maintenance system provided in this application. Figure 5 As shown, the method includes: S201 The willow stake breakage self-excitation sensor module continuously detects the status of the willow stake and automatically generates an alarm data packet when the willow stake in Bio Valley breaks, and pushes the alarm data packet to the system platform and the mobile terminal carried by the willow stake management personnel.

[0072] The alarm data packet includes the willow stake number, breakage time, GPS coordinates, and the type of sensor unit used to detect the willow stake breakage event.

This allows the willow stump management personnel to perform replanting and maintenance operations based on the pushed replanting and maintenance plan.

[0075] S204, the drought-period collaborative infiltration and water storage module performs integrated closed-loop operation of water collection, storage and supply, and provides capillary water supply to the willow root system through capillary water transport carriers pre-embedded in the root zone of the willow stump during drought periods.

[0076] In some embodiments of this application, the willow stump archive data includes the soil type, variety, biodegradable maintenance package burial time, distance from surrounding willow stumps, and load-bearing properties corresponding to the willow stump; the real-time data of the willow stump includes the real-time groundwater level and real-time soil organic matter content; the steps for generating a willow stump replanting and maintenance plan include: S301. Based on the load-bearing attributes, variety, real-time groundwater level, real-time soil organic matter content, and specification matching decision rules of the willow stumps, determine the variety, diameter, and length of the new stumps to be replanted.

[0077] It should be noted that the variety, diameter, and length of the new stumps to be planted in this step can be determined with reference to the specification matching decision rules in Table 1.

[0078] S302. Based on the soil type corresponding to the willow stump, the distance between the stump and the surrounding willow stumps, and the operation adaptation decision rules, determine the planting depth and planting location of the new stump to be replanted.

[0079] The soil types include clay, sandy loam, silt, loam, sandy clay, and clayey loam; the planting location includes the distance between the new stump to be planted and the biodegradable maintenance package, and the distance between the new stump to be planted and other surrounding willow stumps. The planting depth and location of the new stump to be planted in this step can be determined with reference to the operation adaptation decision rules in Table 2.

[0080] S303. Based on the burial time of the biodegradable maintenance package corresponding to the willow stump, the real-time soil volumetric moisture content, the real-time soil organic matter content, and the maintenance adaptation decision rules, determine the amount of rooting agent to be used for the new stump to be replanted, as well as the number of additional watering packages and biodegradable maintenance packages.

[0081] It should be noted that the amount of rooting agent to be used for the new stumps to be replanted in this step, as well as the number of new watering packs and biodegradable maintenance packs, can be determined by referring to the maintenance adaptation decision rules in Table 3.

[0082] S304. Generate a replanting plan for willow stumps based on the variety, diameter, length, planting depth, and planting location of the new stumps to be replanted; and generate a maintenance plan for the willow stumps based on the amount of rooting agent used for the new stumps to be replanted, as well as the number of newly added watering packs and biodegradable maintenance packs.

[0083] In some embodiments of this application, the method for monitoring and maintaining willow stump fractures in bio-valleys also includes the step of establishing a willow stump archive: during the construction phase of the bio-valley, a biodegradable maintenance package is pre-embedded for each willow stump, and the specifications, location, and biodegradable maintenance package embedding information of each willow stump are entered into the system platform to establish a willow stump archive.

[0084] In some embodiments of this application, the drought-period synergistic infiltration and water storage module includes a water collection area and diversion system, an underground water storage facility, and a capillary water transport carrier laid between the underground water storage facility and the willow stump roots.

Rainfall runoff is collected and stored in underground water storage facilities through a catchment area and diversion system.

[0085] S402. The soil volumetric moisture content in the willow stump root zone is monitored using a soil moisture sensor. When the measured soil volumetric moisture content is less than the soil volumetric moisture content threshold, water from the water storage facility is transported to the willow stump root zone via a capillary water transport carrier. The capillary water transport carrier is a ceramic tube or a bio-based fiber rope.

[0086] The willow stump fracture monitoring and maintenance system and method provided in this application for bio-valley construction utilizes a graphite powder-doped bio-based gel conductive circuit and a easily broken bamboo peg lever triggering device to generate a power-free self-excitation signal for willow stump fracture. The conductive circuit, bamboo peg strength, and the mechanical properties of the willow stump and fiber rope are precisely matched, enabling self-excitation and real-time alarm for willow stump fracture. By verifying and associating archival data with willow stump codes and GPS coordinates, and combining specification adaptation decision rules, operation adaptation decision rules, and maintenance adaptation decision rules, refined specifications for replanted stumps, planting details, and maintenance measures can be determined, improving the survival rate of replanted willow stumps. An integrated closed-loop system for water collection, storage, and supply is constructed. By precisely matching all water collection, storage, and supply parameters to a single willow stump, a micro-hydraulic system at the single-tree scale is built, enabling single-stump calculation and targeted supply of water resources. This achieves automatic water replenishment during drought periods, improving water resource utilization.
