Description

Technical Field

[0001] This application relates to the field of intelligent planting, and more particularly, to a solar desert planting system. Background Art

[0002] The core of desertification control is to restore the ecosystem function through vegetation restoration. The current mainstream strategy is "near-natural control", that is, to scientifically design the vegetation density and species combination by planting trees and grass at low density, so as to achieve ecological restoration with minimal intervention. However, there are significant bottlenecks in the efficiency, adaptability and resource utilization of traditional manual planting and mechanized equipment, making it difficult to meet the needs of large-scale desert control.

[0003] At present, desertification control mainly relies on the following technologies: (1) Manual planting: relying on manpower to complete digging, sowing and irrigation, with high labor intensity and low efficiency. Especially in vast desert areas, the manpower input and effectiveness are seriously mismatched; (2) Traditional tree planters: using fuel-driven or fixed designs, although the operation speed is increased, there are defects such as low accuracy, poor environmental adaptability and insufficient resource utilization efficiency (relying on long-distance water conveyance or fossil energy), and the performance is unstable under extreme climates; (3) Fixed irrigation systems: requiring laying pipelines or pumping groundwater, with high energy consumption and difficult to adapt to dynamic terrain, resulting in water resource waste and cost increase.

[0032] The following will describe some implementation manners of the present application in detail with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0033] Embodiment

[0034] Desertification control is a major global environmental challenge, and its core lies in restoring the ecosystem function through vegetation restoration. Currently, the mainstream desertification control strategy is "near-natural control", that is, by adopting the method of low-density afforestation and grass planting, scientifically designing the vegetation density and species combination, and striving to achieve ecological restoration with the least intervention. However, the existing technologies face many challenges in achieving this goal.

[0035] Traditional manual planting methods rely heavily on human labor. From digging holes, sowing seeds to irrigation, the entire process has a large labor intensity and low efficiency. In vast desert areas, there is a significant mismatch between the human input and the actual results, making it difficult to meet the needs of large-scale desert control.

[0036] Although traditional tree planters have improved the operation speed to a certain extent, most of them adopt fuel-driven or fixed designs, which have many drawbacks. Fuel-driven equipment not only consumes a large amount of resources, but also has difficulty in fuel supply in desert areas; the fixed design lacks flexibility and is difficult to adapt to the complex and changeable terrain conditions in desert areas. In addition, these devices also have deficiencies in seeding accuracy, environmental adaptability, and resource utilization efficiency. Especially under extreme climate conditions, their performance is often unsatisfactory.

[0037] Fixed irrigation systems also face many challenges. They need to lay complex pipe networks or rely on groundwater extraction, which not only consumes a high amount of energy, but also is difficult to adapt to the dynamically changing terrain conditions in desert areas. This not only leads to waste of water resources, but also increases the treatment cost.

[0038] In view of the deficiencies of the existing technologies, the present application proposes a solar desert planting system, which integrates mobility, energy self-sufficiency, and water resource recycling, aiming to provide an efficient and environmentally friendly solution for desert ecological restoration.

[0039] Please refer to Figures 1 - 2 and this solar desert planting system includes a mobile vehicle body 1, and a solar power supply module 2, a water collection module 3, a seeding module 4, an irrigation module 5, and a control module 6 provided on the mobile vehicle body 1; the water collection module 3 is used for condensing and collecting moisture in the air; the seeding module 4 includes a longitudinal driving component 42, a seeding pipe 41, a seeding tray 43, a steering gear 44, a baffle 45, and the seeding tray 43; the longitudinal driving component 42 is provided on the mobile vehicle body 1 and is used for driving the seeding pipe 41 to reciprocate vertically; the seeding pipe 41 vertically slides through the bottom of the mobile vehicle body 1, its top is open, the bottom is a cone with the tip facing downwards, and seeding openings 411 are circumferentially spaced on the side wall; the seeding tray 43 is provided in the seeding pipe 41 to divide the inside of the seeding pipe 41 into upper and lower cavities, and a plurality of seed outlet holes 431 are provided on the seeding tray 43; the driving end of the steering gear 44 is connected to the baffle 45 and is used for driving the baffle 45 to block or expose the seed outlet holes 431. When the control module 6 receives a seeding signal, it executes the following loop process until the number of planting rows reaches the target number: S1: Control the mobile vehicle body 1 to travel in a preset direction to a preset plant spacing and then stop; S2: Control the longitudinal driving component 42 to drive the seeding pipe 41 to descend into the sandy soil, so as to trigger the steering gear 44 to drive the turntable to rotate to open the seeding tray 43. After the seeds are put through the seeding openings 411, control the longitudinal driving component 42 to drive the seeding pipe 41 to rise, and simultaneously drive the irrigation module 5 to obtain and spray a first preset amount of water source from the water collection module 3; S3: Judge whether the cumulative travel distance of the mobile vehicle body 1 in the preset direction reaches a preset threshold. If so, control the mobile vehicle body 1 to turn and drive along the planned path to the next row planting position and then return to S1 to continue execution. If not, return to S1 to continue execution.

[0040] For ease of understanding, first in combination with Figure 1 the electrical connection structure part of the system is exemplarily described as follows:

[0041] Among them, the mobile vehicle body 1 serves as the mobile platform of the entire system. The mobile vehicle body 1 can carry other modules to move flexibly in the desert area and reach the designated planting area. This design enables the system to adapt to the complex and changeable terrain conditions in the desert area and improve the treatment efficiency. The solar power supply module 2 is the energy core of the system. It uses solar panels to convert solar energy into electrical energy and provides a stable working voltage for the entire system. As a clean and renewable energy source, solar energy not only reduces the operating cost of the system but also reduces the dependence on traditional energy sources, which conforms to the concepts of environmental protection and sustainable development.

[0042] In response to the problem of water shortage in the desert area, the water collection module 3 condenses the water vapor in the air into liquid water through condensation technology and collects it. These collected waters can be used for subsequent irrigation work, realizing the recycling of water resources and improving the utilization efficiency of water resources.

[0043] The control module 6 serves as the "brain" of the system, responsible for receiving and processing external signals, and issuing instructions according to preset algorithms and strategies to control the work of other modules. For example, it controls the movement of the mobile vehicle body 1, the seeding action of the seeding module 4, and the irrigation action of the irrigation module 5. Through intelligent control, the system can achieve automated operations and improve the treatment efficiency and accuracy.

[0044] In summary, traditional equipment relies on fuel or grid power supply, making power supply difficult and carbon emissions high in desert areas. However, this application uses the solar power supply module 2 to drive the entire system to work, reducing the dependence on traditional energy sources and also reducing the operating cost and environmental burden. At the same time, traditional irrigation relies on long-distance water conveyance or groundwater, which is costly and unsustainable. In this application, the water collection module 3 is used to condense and collect the moisture in the air, which can provide water sources for the irrigation of seeds and plants, not only solving the problem of irrigation water sources in desert areas but also realizing the recycling of water resources.

[0045] Next, in combination with Figures 3 - 8 , the mechanical structure part of the system is exemplarily described as follows:

[0046] Among them, the single-point outlet of the traditional sowing pipe 41 is prone to seed accumulation, and the sandy soil backfill blocks the pipe orifice. In this application, the bottom of the sowing pipe 41 is designed as a cone with the tip facing downwards. The sharp shape is used to penetrate the sandy soil, reducing the insertion resistance. When withdrawing, the sand grains naturally backfill and cover the seeds, which can avoid the blockage of the pipe orifice caused by sand grain accumulation. A plurality of sowing ports 411 (usually 4-6) are evenly spaced along the circumferential direction on the side wall of the bottom of the sowing pipe 41, and the aperture is matched with the seed size (such as 2.5 mm). The seeds enter the sowing pipe 41 through the top opening and are evenly distributed to each sowing port 411 under the action of gravity or auxiliary vibration. After the sowing pipe 41 is inserted into the sandy soil, the seeds are dispersed to the surrounding soil through the circumferential openings, realizing low-density uniform sowing. The longitudinal driving component 42 is arranged on the mobile vehicle body 1 and is used to drive the sowing pipe 41 to reciprocate vertically. Through the drive of the longitudinal driving component 42, the sowing pipe 41 can move up and down, so as to perform sowing operations at different depths. Exemplarily, the longitudinal driving component 42 can be designed based on ball screw transmission. The ball screw is driven by a stepping motor to convert the rotational motion into a linear reciprocating motion of the sowing pipe 41 (the nut of the ball screw is connected to the side wall of the sowing pipe 41), and the insertion depth can be controlled (for example, adjustable from 5-15 cm). Moreover, limit switches can be set at the upper and lower limit positions of the lifting path of the sowing pipe 41 to prevent overload or mechanical collision. The longitudinal driving component 42 can also adopt an electric push rod or a hydraulic structure.

[0047] Exemplarily, such as Figure 6 and Figure 8 As shown, the watering pipe 51 can also be placed in the sowing pipe 41, so that when sowing with the sowing pipe 41, watering the seeds can be carried out synchronously. It should be noted that the other end of the watering pipe 51 is connected to the structure (the water collector 33 in the following text) that stores the water source of the water collecting module 3 through a water pump.

[0048] The sowing tray 43 is arranged in the sowing pipe 41, and a plurality of seed outlet holes 431 are arranged thereon. The design of the seed outlet holes 431 enables the seeds to fall out of the sowing tray 43 in a predetermined manner, enter the sowing pipe 41, and finally be sown into the soil through the sowing ports 411. A steering gear 44 is arranged at the bottom of the sowing tray 43. The steering gear 44 receives the instruction of the control module 6 and drives the baffle 45 to move through its driving end, so as to block or expose the seed outlet holes 431. When the baffle 45 blocks the seed outlet holes 431, the seeds cannot fall out of the sowing tray 43; when the baffle 45 exposes the seed outlet holes 431, the seeds can fall out of the sowing tray 43 in a predetermined manner.

[0049] During actual operation, a certain amount of seeds can be placed in advance in the seeding tube 41 (in the upper cavity of the seeding tube 41). The seeds are located at the top of the seeding tray 43, and the pre-seeding baffle 45 blocks the seed outlet 431 to prevent the seeds from falling. When sowing, after using the control module 6 to control the mobile vehicle body 1 to move to the position where sowing is required, the driving is stopped, and the mobile vehicle body 1 stops at this position. Then, the longitudinal driving assembly 42 drives the seeding tube 41 to slide downward by a certain distance, and the bottom of the seeding tube 41 is embedded in the sand; at the same time, the steering gear 44 drives the baffle 45 to rotate by a certain angle so that the baffle 45 moves away from the seed outlet 431. At this time, some of the seeds at the top of the seeding tray 43 fall downward through the seed outlet 431 to the seeding opening 411 at the bottom of the seeding tube 41 and fall into the sand through the seeding opening 411. Then, the steering gear 44 drives the baffle 45 to rotate back to block the seed outlet 431. At the same time, the control module 6 drives the irrigation module 5 to obtain and spray a preset amount of water source from the water collector 33. At this time, sowing and irrigation are completed, and the longitudinal driving assembly 42 drives the seeding tube 41 to slide upward and reset. After the bottom of the seeding tube 41 leaves the sand, the sand covers the seeds. Then, use the control module 6 to control the mobile vehicle body 1 to move in the desert to reach the next sowing position and continue to repeat the above operations for sowing and irrigation.

[0050] Finally, combined with Figure 2 , an exemplary description of the sowing control process of this system is as follows:

[0051] The working process of this system for sowing in the desert mainly includes three stages:

[0052] (1) Traveling and positioning: Control the mobile vehicle body 1 to move forward in the preset direction and stop after reaching the preset plant spacing, so as to ensure uniform planting spacing. It should be noted that this preset direction is determined according to the planting plan. For example, it can be a straight line to ensure consistent row spacing for planting. The preset plant spacing (such as 0.5 - 2 meters) is set in advance according to the growth requirements of the crops and the requirements of planting density to ensure that there is a suitable growth space between each plant.

[0053] (2) Sowing stage: The seeding tube 41 descends and inserts into the sand, triggering the baffle 45 to open, and the seeds fall into the lower cavity and enter the soil through the seeding opening 411. When the seeding tube 41 rises, irrigation is started synchronously to spray the first preset amount of water source to form a local humid environment. It should be noted that releasing the seeds after the seeding tube 41 is inserted into the sand can prevent the seeds from being blown away by the wind or eaten by animals; and the local humid environment formed by synchronous irrigation can improve the germination rate. Among them, the first preset amount is determined in advance according to factors such as the type of seeds and the humidity of the sand, and can provide suitable moisture for the just-sown seeds to promote the germination and growth of the seeds.

[0054] (3) Path management: When single-column planting is completed (reaching the preset threshold), the vehicle body automatically turns and enters the next column along the planned path to achieve grid planting. During this period, the control module 6 will determine whether the cumulative travel distance of the mobile vehicle body 1 in the preset direction reaches the preset threshold. The preset threshold is set according to factors such as the planting area and the number of planting columns, and represents the length of the current planting column. If the cumulative travel distance reaches the preset threshold, it means that the planting task of the current column is completed. The control module 6 will command the mobile vehicle body 1 to turn and drive to the next column planting position along the planned path, and then return to step S1 to continue the loop process. If the cumulative travel distance does not reach the preset threshold, it means that the current column has not been planted yet, and it will return to step S1 to continue sowing and irrigating the next plant according to the preset plant spacing.

[0055] Based on the foregoing solution, in some implementation manners of the present application, the system further includes: an image analysis module, configured to periodically take photos or video streams of the target plants through a camera to analyze the leaf health status and the plant growth status, and obtain plant status judgment information; and when the plant status judgment information indicates that irrigation needs to be performed, send the generated irrigation signal to the control module 6; when the control module 6 receives the irrigation signal, perform the following processing steps: according to the irrigation signal, drive the irrigation module 5 to obtain and spray a second preset amount of water source from the water collection module 3.

[0056] It should be noted that through the image analysis module, the system can realize intelligent monitoring of the growth status of the target plants. This helps to timely detect the growth problems of the plants, such as water shortage, fertilizer shortage, etc., so as to take corresponding measures for intervention. Among them, when there is a water shortage, the irrigation module 5 can be driven to obtain and spray a preset amount of water source from the water collection module 3 to supplement water for the target plants.

[0057] Based on the foregoing solution, in some implementation manners of the present application, the periodically taking photos or video streams of the target plants through a camera to analyze the leaf health status and the plant growth status includes: periodically taking photos or video streams of the target plants through a camera; obtaining and analyzing the RGB color data carried in the photos or video streams to determine the leaf health status according to the color characteristics of the target plants obtained through the analysis; and obtaining and analyzing the geometric attributes carried in the photos or video streams to determine the plant growth status according to the contour data of the leaves and / or fruits of the plants obtained through the analysis.

[0058] It should be noted that by extracting RGB (red, green, and blue) color data from photos or video streams, the health status of leaves can be analyzed through color features. For example, healthy leaves usually exhibit a specific green range, while yellowing may indicate water shortage or other problems. At the same time, contour detection algorithms (such as Canny edge detection, Hough transform, etc.) are combined to determine the boundaries of leaves or fruits, and geometric properties such as their area and perimeter are calculated to further evaluate the overall health status of the plant. Based on this information, the control module 6 will be able to make more accurate irrigation decisions to ensure that each plant receives an appropriate amount of water. For example, color (weight 60%) and geometry (weight 40%) features can be combined to output a health value from 0 to 100, and then based on the health value, it can be determined whether irrigation is needed and how much to irrigate. For instance, an irrigation trigger threshold can be set. When the health value < 70 or the weekly growth rate of the leaf area < 3%, an irrigation instruction (5 - 10 ml / plant) is generated. Or, when the health index is lower than the set threshold (such as < 60 points), an irrigation instruction is sent to the control module 6, and the water volume is recommended (such as mild water shortage: 50 ml / plant, severe water shortage: 100 ml / plant).

[0059] Exemplarily, when analyzing the RGB color data, the R, G, and B channels can be separated, a healthy leaf green index can be established (such as G / (R + B) > 1.2), and abnormal states such as yellow leaves (G value decrease > 20%) and withered leaves (R > G and B < 50) can be identified.

[0060] Based on the foregoing solution, in some implementation manners of the present application, the system further includes a temperature and humidity sensor, and the temperature and humidity sensor is used to obtain the temperature and humidity data of the environment and send them to the control module 6; the control module 6 is further used to adjust the amount of the first preset water source and / or the second preset water source according to the received temperature and humidity data.

[0061] It should be noted that the control module 6 receives the temperature and humidity data sent by the temperature and humidity sensor, and then based on these data, the control module 6 can judge the temperature and humidity conditions of the current environment and accordingly adjust the amount of water source that drives the irrigation module 5 to obtain and spray from the water collector 33 (adjust the amount of the first preset water source and / or the second preset water source). For example, in the case of high temperature and low humidity, the control module 6 may increase the irrigation amount to ensure that the plants receive sufficient water; while in the case of low temperature and high humidity, the control module 6 may reduce the irrigation amount to avoid problems caused by excessive water.

[0062] By monitoring the temperature and humidity of the environment in real time, the system can more accurately judge the water requirements of seeds / plants. Thus, during the process of seed planting and subsequent plant irrigation, precise irrigation can be achieved, avoiding problems such as over-irrigation or under-irrigation, and improving the utilization efficiency of water resources. Moreover, adjusting the irrigation amount according to the changes in environmental temperature and humidity helps the seeds survive.

[0063] Based on the foregoing solution, in some implementation manners of the present application, the control module 6 is further configured to closed-loop control the condensation temperature of the water collection module 3 through a PID algorithm, and dynamically adjust the condensation temperature according to the received temperature and humidity data.

[0064] In some of the above implementation manners, the control module 6 uses a PID (Proportional-Integral-Derivative) algorithm to perform closed-loop control on the condensation temperature of the water collection module 3, so that the condensation temperature can be monitored in real time, and the control amount can be automatically adjusted according to the deviation, keeping the condensation temperature near the set value. Moreover, the control module 6 also dynamically adjusts the condensation temperature according to the received temperature and humidity data, which can further improve the water collection efficiency and the ability to save energy and reduce consumption.

[0065] Based on the foregoing solution, in some implementation manners of the present application, the system further includes an intelligent obstacle avoidance module, which is configured to obtain the road conditions and obstacle information ahead by using a camera and / or an infrared sensor, generate a vehicle adjustment control signal according to the obtained road conditions and obstacle information ahead, and send it to the control module 6; the control module 6 is further configured to control the mobile vehicle body 1 to avoid obstacles according to the received vehicle adjustment control signal.

[0066] It should be noted that the camera can capture the visual image ahead, identify the road boundary, the position and type of obstacles, etc.; the infrared sensor can detect the distance and azimuth of the obstacle ahead by emitting and receiving infrared signals. Thus, the intelligent obstacle avoidance module can obtain the road conditions and obstacle information ahead in real time through the camera and the infrared sensor, generate the corresponding vehicle adjustment control signal, and transmit these to the control module 6. Then, the control module 6 can process and analyze according to the received vehicle adjustment control signal, and judge the key parameters such as the position, size, and moving speed of the obstacle. Then, according to the analysis result, the intelligent obstacle avoidance module will control the mobile vehicle body 1 to avoid the obstacle, such as controlling the mobile vehicle body 1 to avoid the obstacle by changing parameters such as the steering angle and the driving speed. The control module 6 can control the mobile vehicle body 1 to avoid the obstacle according to the received vehicle adjustment control signal, which reduces the need for manual intervention and enables it to better adapt to the environment of uninhabited areas such as deserts, so as to better carry out planting operations in the desert.

[0067] Based on the foregoing solution, in some implementation manners of the present application, the system further includes a solar light tracking module, which is used to detect sunlight through a photosensitive sensor to obtain solar light state information, and is used to control the steering angle of the solar panel of the solar power supply module 2 according to the solar light state information and the electric energy storage information of the solar power supply module 2.

[0068] In the above-mentioned some implementation manners, the solar light tracking module integrates a photosensitive sensor for detecting the intensity and direction of sunlight. Through the photosensitive sensor, the system can obtain the state information of sunlight in real time, including the light intensity, light direction, etc. Thus, it can analyze according to the solar light state information and the electric energy storage information of the solar power supply module 2, and calculate the optimal steering angle of the solar panel. Then, the control module 6 can respond to these calculation results and drive the solar panel of the solar power supply module 2 to adjust the steering angle to maximize the reception of sunlight and convert it into electric energy, thereby significantly improving the utilization rate of solar energy and reducing energy waste.

[0069] Based on the foregoing solution, in some implementation manners of the present application, the system further includes a wireless communication module, which is used to communicate with a mobile terminal to set an operation area, seeding density, and irrigation strategy through the mobile terminal, and to display environmental parameters and system operation status in real time.

[0070] In the above-mentioned some implementation manners, the wireless communication module is integrated into the system for establishing a communication connection with a mobile terminal (such as a smart phone, a tablet computer, etc.). Through this module, the system can receive instructions and data from the mobile terminal and feedback the state information and environmental parameters of the system to the mobile terminal. Among them, the mobile terminal serves as an interface for users to interact with the system, allowing users to remotely set the operation area, seeding density, and irrigation strategy. Thus, users can view environmental parameters (such as temperature, humidity, etc.) and system operation status (such as battery power, irrigation progress, etc.) in real time through the mobile terminal.

[0071] In summary, the introduction of the wireless communication module enables users to monitor the operation status and environmental parameters of the system through the mobile terminal anytime and anywhere. Users can adjust the operation area, seeding density, and irrigation strategy without being present on site, greatly improving the flexibility and convenience of the system. Moreover, by remotely setting operation parameters through the mobile terminal, users can quickly respond to changes in the environment or planting requirements, and timely adjust the system configuration, which helps to reduce the time cost of manual intervention and on-site operation and improve the operation efficiency.

[0072] Please refer to Figure 3 、 Figure 4 and Figure 9, Based on the foregoing solution, in some implementation manners of the present application, the water collection module 3 includes a condensing pipe 31 with both ends open and inclined on the top of the moving vehicle body 1, and further includes a plurality of thermoelectric coolers 32 disposed inside the condensing pipe 31 and a water collector 33 disposed at the lower end of the condensing pipe 31 in terms of height.

[0073] It should be noted that the condensing pipe 31 is inclined and disposed on the top of the moving vehicle body 1. This design enables the water vapor in the air to come into contact with the inner wall of the condensing pipe 31 more effectively when flowing inside the condensing pipe 31, thereby increasing the condensation efficiency. And the inclined setting can utilize gravity to make the condensed water droplets flow naturally towards the water collector 33, avoiding water retention or secondary evaporation. A plurality of thermoelectric coolers 32 are evenly distributed on the inner wall of the condensing pipe 31, with the cold ends facing the lumen, and the heat ends discharge heat through heat sinks (external or air-cooled). Based on the Peltier effect, after being powered on, the temperature of the cold ends can be reduced below the dew point (the dew point at night in the desert is usually 5-15 °C), enabling the flowing water vapor to condense quickly. Exemplarily, the thermoelectric coolers 32 and the solar power supply module 2 can be designed in a coordinated manner, storing energy and supplying power during the day and operating intensively during the low-temperature and high-humidity periods at night, thereby optimizing the energy consumption efficiency.

[0074] Please refer to Figure 3 , Figure 4 and Figure 9 , Based on the foregoing solution, in some implementation manners of the present application, the water collection module 3 further includes a fan 34, and the fan 34 is disposed at one open end of the condensing pipe 31 or at both open ends of the condensing pipe 31, and the fan 34 is electrically connected to the solar power supply module 2.

[0075] In the above-mentioned some implementation manners, a fan 34 (usually the air inlet) is disposed at one open end of the condensing pipe 31, so that the air flow into the condensing pipe 31 can be accelerated by forced air supply, increasing the contact frequency between the water vapor and the cold ends of the thermoelectric coolers 32 and improving the condensation efficiency. Of course, a fan 34 can also be added at one or both open ends of the condensing pipe 31. One end is an air inlet fan 34 (accelerating air inhalation), and the other end is an exhaust fan 34 (forming a negative pressure to enhance the air flow circulation), jointly improving the air flow efficiency.

[0076] It should be noted that the unidirectional flow design (single-end fan 34): The air is inhaled from the air inlet, flows through the cold ends of the condensing pipe 31 and then naturally discharges from the other end, which is suitable for environments with large day-night temperature differences and strong natural convection. The circulating flow design (double-end fan 34): The air inlet and exhaust fans 34 work together to form a closed-loop air flow, prolonging the residence time of the air in the condensing pipe 31, which is suitable for dry and calm environments.

[0077] It is obvious to those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
