Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration and intelligent control, and specifically to an intelligent maintenance system for slope greening and its working method. Background Art

[0002] With the acceleration of the urbanization process and the enhancement of ecological environment protection awareness, slope greening has been widely applied in aspects such as mine reclamation, road slope protection, and urban mountain greening. However, there are many bottlenecks and deficiencies in the traditional slope greening maintenance methods. The main problems are strong dependence on manual labor, extensive management, untimely maintenance, low resource utilization efficiency, etc. These problems not only increase the labor and material costs, but also affect the long-term stability and ecological benefits of slope greening projects to a certain extent.

[0003] Traditional maintenance mainly relies on manual measurement and judgment of indicators such as soil humidity and fertility. This method has obvious lag and subjectivity, which easily leads to inaccurate irrigation and fertilization, resulting in waste of water resources or overuse of fertilizers, and then affecting the vegetation growth and coverage effect. At the same time, in high-steep slopes and dangerous areas, manual operation faces great risks, the operation difficulty is large, and it is difficult to achieve real-time monitoring and timely response. With the development of Internet of Things technology, artificial intelligence technology and robotics technology, intelligent maintenance of slope greening has gradually become a research and practice hotspot. The combination of the Internet of Things and intelligent sensors makes real-time monitoring possible. By deploying multi-point monitoring sensors on slopes, data such as soil humidity, fertility, and meteorological parameters can be dynamically obtained and transmitted to the background system in real time through wireless transmission technology.

[0004] Existing slope greening intelligent maintenance systems have deficiencies in many aspects in application. First of all, the layout of monitoring points is unreasonable, and the monitoring data is greatly affected by local environmental differences, lacking integrity and continuity, resulting in insufficient decision-making accuracy. At the same time, the data transmission path of the system is relatively single. When a certain node fails, it may cause the entire transmission link to be interrupted, affecting the integrity and continuity of data collection. In addition, the adaptability of some automation devices in high-steep slopes, gravel areas and vegetation-dense areas is weak, the movement and operation of the devices are limited, and the effect of automated maintenance is affected. In terms of water and fertilizer conservation, traditional intelligent irrigation systems are difficult to accurately control the irrigation volume and fertilization amount, and are difficult to make adaptive adjustments according to meteorological changes, which easily causes waste of resources or poor vegetation growth. At the same time, the existing system lacks effective monitoring of the device status and faults, and it is difficult to detect and handle faults in time, affecting the stability and reliability of the system operation.

[0005] Therefore, the present invention proposes an intelligent maintenance system for slope greening and its working method to solve the deficiencies of the prior art. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an intelligent maintenance system for slope greening and its working method, which solves the problems of low efficiency, resource waste, and insufficient adaptability existing in traditional slope greening maintenance.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent maintenance system for slope greening includes a slope body, on which multiple levels of steps are provided. On each level of the steps, multiple rows of semi-circular slope-fixing frames are arranged. Between every two rows of the semi-circular slope-fixing frames, a row of rotating spray guns is arranged. The rotating spray guns correspond to the semi-circular slope-fixing frames one by one. Each rotating spray gun is controlled by an independent pipeline solenoid valve. For each row, an intelligent sensor is arranged every two semi-circular slope-fixing frames, and each intelligent sensor is controlled by an independent line solenoid valve. The intelligent sensors are connected to a data collector, which is arranged in a layered manner on the step structure. A water storage tank is arranged beside the slope body. A water absorption pipeline and a water inlet pipeline are laid in the slope body. The water storage tank is connected to the water absorption end of the water absorption pipeline. The water absorption pipeline is connected to a water supply pipeline, and the water supply pipeline is connected to a high-pressure pipeline, which is connected to the rotating spray guns.

[0008] Preferably, the rotating spray guns are connected to a maintenance box through a maintenance pipeline, and a pipeline solenoid valve is also arranged on the maintenance pipeline.

[0009] Preferably, a walking platform is arranged at the junction of each level of the steps. A drain ditch is provided at the edge of the walking platform, and the bottom of the drain ditch is connected to the water storage tank through a water inlet pipeline.

[0010] Preferably, a blocking net is provided at the end of the water inlet pipeline away from the water storage tank.

[0011] Preferably, a limiter is arranged on the top of the water storage tank, which is connected to the pipeline solenoid valve on the water inlet pipeline. When the water level in the water storage tank reaches the set height of the limiter, the pipeline solenoid valve closes.

[0012] Preferably, an external water inlet pipeline is connected to the outside of the water storage tank.

[0013] Preferably, it further includes a storage battery and a wire arrangement. The storage battery is connected to the wire arrangement, which is laid in the slope body. The wire arrangement is connected to the intelligent sensors, rotating spray guns, data collector, pipeline solenoid valves, limiter, and line solenoid valves.

[0014] The present invention also provides a working method for the intelligent maintenance system of slope greening, including the following steps: S1. The intelligent sensors are independently powered through the line solenoid valves and continuously monitor the soil humidity and fertility data. The monitored data is transmitted to the data collector corresponding to the step level through the line solenoid valves; S2. The data collector classifies the received data in a stepped and hierarchical manner and uploads it to the background system. The background system generates irrigation or fertilization instructions based on preset thresholds. S3. If the soil humidity is lower than the threshold, the background system sends an irrigation instruction to the pipeline solenoid valve of the water absorption pipeline; if the soil fertility is insufficient, it sends a fertilization instruction to the pipeline solenoid valve of the maintenance pipeline. S4. In the irrigation mode, the pipeline solenoid valve of the water absorption pipeline is opened, and the high-pressure pipeline pressurizes the water to the rotating spray gun for sprinkler irrigation. In the fertilization mode, the pipeline solenoid valve of the maintenance pipeline is opened, and the nutrients in the maintenance box are sprayed through the rotating spray gun. S5. The limiter monitors the water level of the reservoir in real time. When the water level reaches the set height, it closes the pipeline solenoid valve of the water inlet pipeline; when the water level is lower than the safety threshold, water source replenishment is carried out through the external water inlet pipeline. S6. When the intelligent sensor or the rotating spray gun fails, the corresponding line solenoid valve or pipeline solenoid valve automatically closes. The background system triggers an alarm and marks the fault location, and manual intervention is carried out for targeted maintenance.

[0015] The present invention provides a slope greening intelligent maintenance system and its working method. It has the following beneficial effects: 1. Through the Internet of Things technology and intelligent sensor network, the system in the present invention can collect key parameters such as soil humidity and fertility in real time and transmit them to the control system, providing a scientific basis for maintenance decision-making. This real-time data-driven management mode significantly improves the accuracy and timeliness of maintenance, and avoids resource waste and vegetation damage caused by information lag or judgment errors in traditional manual maintenance.

[0016] 2. The present invention uses artificial intelligence and machine learning algorithms to deeply analyze the collected data, predict the vegetation growth trend and potential risks, and automatically generate the optimal maintenance plan. For example, by combining soil humidity and weather forecasts, it can intelligently adjust the irrigation volume and frequency, which not only avoids water resource waste but also ensures the healthy growth of vegetation. At the same time, through independently controlled pipeline solenoid valves and line solenoid valves, precise execution is realized, greatly reducing the labor cost and improving the maintenance efficiency.

[0017] 3. Through the modular design of the rotating spray gun, maintenance pipeline and independently controlled solenoid valve system, the system in the present invention can operate efficiently in high-steep slopes, dangerous areas or harsh environments, reducing the risk of manual intervention. For example, in areas where traditional maintenance is difficult to implement, the system realizes automated irrigation, fertilization and drainage management through the cooperation of hierarchical data collectors and walking platforms, significantly expanding the applicable scope of slope greening projects.

[0018] 4. The present invention collects rainwater through a drainage ditch and an intake pipe, dynamically regulates the water level of the reservoir in combination with a limiter, and realizes the recycling of water resources; at the same time, the precise maintenance strategy optimizes resource allocation, significantly improves the survival rate and coverage rate of vegetation, effectively prevents soil erosion, improves the ecological environment, and conforms to the core concept of green development.

[0019] 5. The intelligent slope greening maintenance system of the present invention realizes the intelligence, precision and high efficiency of the maintenance process through technological innovation, provides strong support for ecological restoration, resource conservation and environmental protection, and has broad application prospects and social benefits.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1 - attached Figure 7, an embodiment of the present invention provides an intelligent maintenance system for slope greening, including a slope body. There are multiple levels of steps on the slope body. Multiple rows of semi-circular slope-fixing frames 2 are arranged on each level of step. One row of rotating spray guns 4 is arranged between every two rows of semi-circular slope-fixing frames 2. The rotating spray guns 4 correspond to the semi-circular slope-fixing frames 2 one by one. Each rotating spray gun 4 is controlled by an independent pipeline solenoid valve 12. One intelligent sensor 1 is arranged every two semi-circular slope-fixing frames 2 in each row, and each intelligent sensor 1 is controlled by an independent line solenoid valve 19. The intelligent sensor 1 is connected to a data collector 5. The data collector 5 is arranged in layers on the step structure. A water storage tank 14 is arranged beside the slope body. A water absorption pipeline 6 and a water inlet pipeline 13 are laid in the slope body. The water absorption end of the water absorption pipeline 6 is connected to the water storage tank 14. The water absorption pipeline 6 is connected to a water supply pipeline 20. The water supply pipeline 20 is connected to a high-pressure pipeline 17. The high-pressure pipeline 17 is connected to the rotating spray gun 4. The rotating spray gun 4 is connected to a maintenance box 8 through a maintenance pipeline 7. A pipeline solenoid valve 12 is also arranged on the maintenance pipeline 7. A footpath platform 11 is arranged at the junction of each level of step. A drain ditch 3 is arranged at the edge of the footpath platform 11. The bottom of the drain ditch 3 is communicated with the water storage tank 14 through the water inlet pipeline 13. A blocking net 16 is arranged at one end of the water inlet pipeline 13 far from the water storage tank 14. A limiter 15 is arranged on the top of the water storage tank 14. The limiter 15 is connected to the pipeline solenoid valve 12 on the water inlet pipeline 13. When the water level in the water storage tank 14 reaches the set height of the limiter 15, the pipeline solenoid valve 12 closes. An external water inlet pipeline 9 is communicated with the outside of the water storage tank 14. It also includes a storage battery 10 and a wire arrangement 18. The storage battery 10 is connected to the wire arrangement 18. The wire arrangement 18 is laid in the slope body. The wire arrangement 18 is connected to the intelligent sensor 1, the rotating spray gun 4, the data collector 5, the pipeline solenoid valve 12, the limiter 15 and the line solenoid valve 19.

[0024] Specifically, the overall slope body presents a multi-level stepped structure. The basic shape of the slope body is pre-shaped manually, and the required water absorption pipeline 6, water inlet pipeline 13 and wire arrangement 18 are laid inside the slope body during the shaping process to form a complete basic network system.

[0025] The surface of each level of step structure is evenly provided with multiple rows of semi-circular slope-fixing frames 2. The diameter of the semi-circular slope-fixing frames 2 is about 1-2 meters. The semi-circular slope-fixing frames 2 are arranged closely to improve the overall stability of the slope surface. Green plants or shrubs can be planted inside to enhance the vegetation coverage rate and the stability of the slope soil. A rotating spray gun 4 is arranged between two rows of semi-circular slope-fixing frames 2 and is independently controlled by the corresponding pipeline solenoid valve 12, which can flexibly perform local or overall spraying tasks.

[0026] To achieve intelligent monitoring and response control, within each row of semi-circular slope-fixing frames 2, an intelligent sensor 1 is set every two frames for collecting environmental parameters such as soil humidity and fertility. Each intelligent sensor 1 is connected to the control circuit system through an independent line solenoid valve 19, and the data it collects is transmitted to the data collector 5. The data collectors 5 are arranged layer by layer according to the step distribution law, so as to achieve hierarchical processing and better pursue the authenticity and reliability of the data.

[0027] The data collector 5 uploads the obtained information to the management system, and the background program automatically judges the green plant maintenance requirements according to the real-time data and issues relevant instructions to control the corresponding pipeline solenoid valve 12 or line solenoid valve 19. For example, when the intelligent sensor 1 in a certain area detects insufficient soil humidity, the system will instruct the corresponding pipeline solenoid valve 12 to open, start the water absorption pipeline 6, pump water from the water storage tank 14 and transport it to the corresponding rotating spray gun 4 to achieve automatic irrigation.

[0028] In terms of water storage and drainage, a water storage tank 14 is set on the side of the slope, which is mainly used for collecting rainwater and external input water sources. A limiter 15 is set on the top of the water storage tank 14, which can trigger the solenoid valve to close the pipeline solenoid valve 12 of the water inlet pipeline 13 when the water level reaches the upper limit to prevent water from overflowing. The water storage tank 14 is connected to the external water inlet pipeline 9 through the water inlet pipeline 13. During rainfall, the drain ditch 3 arranged along the slope and the footpath platform 11 diverts the rainwater to the water inlet pipeline 13, and after filtering impurities through the blocking net 16, it enters the water storage tank 14 to achieve efficient rainwater recovery. The purpose of the blocking net 16 is to block large garbage or other decaying green plants from entering the water inlet pipeline 13, thus blocking the pipeline.

[0029] The water absorption pipeline 6 is connected to the water supply pipeline 20 and then connected to the rotating spray gun 4 through the high-pressure pipeline 17 to ensure sufficient irrigation pressure. In addition, the water absorption pipeline 6 is connected to the maintenance box 8 through the maintenance pipeline 7, and nutrients or agents are stored in the maintenance box 8. When the system judges that fertilization or vegetation maintenance is required, the pipeline solenoid valve 12 of the maintenance pipeline 7 is opened, and the nutrients are transported through the pipeline to the specified rotating spray gun 4 to complete precise spraying.

[0030] To improve the human-computer interaction and the convenience of later maintenance, a footpath platform 11 is provided at the junction of each step. A drain ditch 3 is set at the edge of the footpath platform 11, which has good drainage function and is convenient for personnel to patrol and operate. The overall system uses the battery 10 as the main power supply, and at the same time is equipped with solar and wind energy devices and has an external power supply interface to ensure the continuous operation ability of the system in different environments.

[0031] This system emphasizes the module independence and information linkage mechanism, and each key device has the ability of independent control and intelligent response. For example, when the intelligent sensor 1 or the rotary spray gun 4 fails, the corresponding line solenoid valve 19 or the pipeline solenoid valve 12 automatically closes to prevent the spread of the fault; meanwhile, the background system marks the fault location, and the maintenance personnel can quickly locate and repair it.

[0032] The storage battery 10 serves as the main power supply, and is connected to the solar power generation module and the wind power generation module through the wire arrangement 18 to realize the storage and distribution of renewable energy; meanwhile, the storage battery 10 is provided with an external power supply interface for supplementing power in extreme weather or when the energy is insufficient to ensure the continuous operation of the system. The wire arrangement 18 adopts a waterproof and insulating cable, which is embedded inside the slope body to avoid environmental erosion. Its branch structure is respectively connected to the following devices: providing an independent power supply and signal transmission line for the intelligent sensor 1; driving the motor of the rotary spray gun 4 and receiving control signals; ensuring the data processing and communication power supply of the data collector 5; controlling the opening and closing of the pipeline solenoid valve 12 of the water absorption pipeline 6, the maintenance pipeline 7 and the water inlet pipeline 13; providing power and a feedback signal path for the position limiter 15 to monitor the water level of the reservoir 14 in real time; and independently managing the communication link of the intelligent sensor 1 through the line solenoid valve 19 to realize fault isolation and modular control.

[0033] Please refer to the appendix Figure 1 - Appendix Figure 7 , the present invention also provides a working method for the intelligent maintenance system of slope greening, including the following steps: S1. The intelligent sensor 1 is independently powered through the line solenoid valve 19 and monitors the soil humidity and fertility data in real time. The monitored data is transmitted to the data collector 5 of the corresponding step level through the line solenoid valve 19; S2. The data collector 5 classifies the received data by step levels and uploads it to the background system. The background system generates irrigation or fertilization instructions according to the preset thresholds; S3. If the soil humidity is lower than the threshold, the background system sends an irrigation instruction to the pipeline solenoid valve 12 of the water absorption pipeline 6; if the soil fertility is insufficient, a fertilization instruction is sent to the pipeline solenoid valve 12 of the maintenance pipeline 7; S4. In the irrigation mode, the pipeline solenoid valve 12 of the water absorption pipeline 6 is opened, and the high-pressure pipeline 17 increases the pressure to transport water to the rotary spray gun 4 for sprinkler irrigation. In the fertilization mode, the pipeline solenoid valve 12 of the maintenance pipeline 7 is opened, and the nutrients in the maintenance box 8 are sprayed through the rotary spray gun 4; S5. The position limiter 15 monitors the water level of the reservoir 14 in real time. When the water level reaches the set height, the pipeline solenoid valve 12 of the water inlet pipeline 13 is closed; when the water level is lower than the safety threshold, water source replenishment is carried out through the external water inlet pipeline 9; S6. If the intelligent sensor 1 or the rotary spray gun 4 fails, the corresponding line solenoid valve 19 or the pipeline solenoid valve 12 automatically closes, the background system triggers an alarm and marks the fault location, and manual intervention is carried out for targeted maintenance.

[0034] Specifically, for step S1, the intelligent sensor 1 is independently powered through the line solenoid valve 19, and real-time monitors the soil humidity and fertility data in its corresponding area. Since each intelligent sensor 1 controls the power supply and communication link through an independent line solenoid valve 19, when a certain sensor fails, only the corresponding line solenoid valve 19 needs to be closed, and other sensors can still work normally, ensuring the continuous operation of the system. The monitoring data is transmitted to the data collector 5 at the corresponding step level through the line solenoid valve 19, realizing the step-by-step hierarchical summary of data and avoiding signal cross-interference.

[0035] For step S2, the data collector 5 performs step-by-step hierarchical classification processing on the received data. For example, the data of multiple intelligent sensors 1 within the same step level are averaged or outliers are screened. The processed data is uploaded to the background system. The background system generates decision instructions based on the preset soil humidity and fertility thresholds: if the soil humidity in a certain area is lower than the threshold, an irrigation instruction is triggered; if the fertility is insufficient, a fertilization instruction is triggered. The decision logic is independently judged based on the step level to ensure the accuracy of the maintenance operation.

[0036] For step S3, irrigation instruction: The background system sends an opening instruction to the pipeline solenoid valve 12 of the water absorption pipeline 6, the high-pressure pipeline 17 starts to boost the pressure, and the water flows through the water absorption pipeline 6 and the water supply pipeline 20 to the target rotary spray gun 4 for sprinkler irrigation of the specified area.

[0037] Fertilization instruction: The background system sends an opening instruction to the pipeline solenoid valve 12 of the maintenance pipeline 7, and the liquid nutrient in the maintenance box 8 is transported to the rotary spray gun 4 through the maintenance pipeline 7 and sprayed to the target area.

[0038] For step S4, irrigation mode: After the pipeline solenoid valve 12 of the water absorption pipeline 6 is opened, the high-pressure pipeline 17 raises the water pressure to the working requirement value, and the rotary spray gun 4 performs directional sprinkler irrigation on a single or multiple semi-circular slope protection frames 2 according to the instruction, and the sprinkler irrigation range matches the vegetation distribution of the corresponding semi-circular slope protection frame 2.

[0039] Fertilization mode: After the pipeline solenoid valve 12 of the maintenance pipeline 7 is opened, the nutrient and water are mixed in a preset ratio and atomized and sprayed through the rotary spray gun 4 to ensure that the nutrient evenly covers the soil in the target area.

[0040] For step S5, the position limiter 15 real-time monitors the water level of the reservoir 14: Water level overrun protection: When the water level reaches the set height, the position limiter 15 sends a closing instruction to the pipeline solenoid valve 12 of the water inlet pipeline 13 to stop the external water source or rainwater from entering and prevent overflow.

[0041] Water source replenishment mechanism: When the water level is lower than the safety threshold, water source replenishment is carried out through the external water inlet pipe 9.

[0042] For step S6, fault detection and isolation: If the intelligent sensor 1 or the rotary spray gun 4 fails (such as signal interruption or spray gun blockage), the corresponding line solenoid valve 19 or the pipeline solenoid valve 12 automatically closes to cut off the power supply or water flow and prevent the spread of the fault.

[0043] Alarm and manual maintenance: The background system triggers an audible and visual alarm and marks the fault location coordinates on the control interface (such as "sensor fault in the 5th row of the 3rd - level ladder"), and the maintenance personnel perform targeted maintenance through the walkway platform 11 according to the marked location. After replacing or repairing the faulty module, restarting the corresponding solenoid valve can resume operation.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
