Description

Technical Field

[0001] The present invention relates to the technical field of garden maintenance, in particular to a high-efficiency intelligent solar-driven garden drip irrigation device. Background Art

[0002] Landscaping is the creation of a beautiful natural environment and recreational space within a specific area through the application of engineering technology and artistic means, through the transformation of terrain (or further development through the construction of mountains, stone stacking, and water management), the planting of trees, flowers, and plants, the construction of buildings, and the layout of paths. This is called a garden. Gardens include courtyards, residential gardens, small gardens, flower gardens, parks, botanical gardens, and zoos. With the development of the discipline of landscape architecture, it also includes forest parks, scenic spots, tourist areas within nature reserves or national parks, and recreational resorts.

[0003] Greening maintenance, that is, the later watering, pruning, weeding, spraying, and seedling replacement after completing greening construction, is collectively called maintenance. The work is simple, but necessary and very important.

[0004] The existing patent document with the announcement number CN216821114U discloses a garden planting and maintenance drip irrigation device, which is used in conjunction with a solar panel, a support plate, a water collection tank, and a battery. The solar panel is installed in the center of the water collection tank through the support plate. The solar panel then converts solar energy into electrical energy, which is then stored in the battery. The battery then powers a water level detector, a water pump, an electric valve, and a controller, thereby continuously charging the battery, increasing the device's battery life and achieving energy conservation and environmental protection. The fixed pin and the filter tube are used in conjunction to enable the filter tube to filter rainwater. At the same time, by pulling the fixed pin out of the water collection tank, the filter tube is released from the fixation, making it easier for workers to clean impurities inside the filter tube. The first telescopic tube is used in conjunction with the first telescopic tube, which can be extended or shortened to facilitate workers to adjust the position between the drip irrigation and the plant as needed, thereby assisting the growth of the plant root system and being suitable for plants of different sizes. The threaded tube, the threaded sleeve, the leaking pipe, and the drill bit are used in conjunction to rotate the screw. The corrugated pipe drives the leakage pipe and the drill bit to rotate, and drives the drill bit to be inserted into the ground, so that the threaded pipe continues to move downward and the leakage pipe is also inserted into the ground, thereby achieving the purpose of fixing the drip irrigation pipe and drip irrigation of plants; through the coordinated use of water level detector, water tank, controller, electric valve and water inlet pipe, when the water level detector detects that the internal water level of the water tank is low, the controller controls the electric valve to open the water inlet of the water inlet pipe, so that the pipe buried in the garden discharges water into the interior of the water tank, and then the controller controls the electric valve to close the water inlet of the water inlet pipe, and the rainwater is collected in the water collecting tank. The water is collected in a row, which is convenient for solving the problem of water supply inside the water tank according to demand and reducing the use of manpower. Through the coordinated use of the controller, the water pump, the water outlet pipe, the first telescopic pipe, the drip irrigation pipe, the second telescopic pipe and the leakage pipe, the water pump passes the water outlet pipe, the first telescopic pipe, the drip irrigation pipe and the second telescopic pipe into the interior of the threaded pipe and the other second telescopic pipe respectively, and the water enters the interior of the next drip irrigation pipe through the other second telescopic pipe. At the same time, the water enters the interior of the leakage pipe through the threaded pipe, and then is drained out through the leakage holes on the outer surface of the leakage pipe, thereby achieving the purpose of drip irrigation.

[0005] Although the above-mentioned garden planting and maintenance drip irrigation device can solve the corresponding technical problems, when the filter tube is blocked by impurities and needs to be cleaned during use, it is necessary to manually disassemble the filter tube, process it and reinstall it. The maintenance operation is relatively cumbersome, and there is a phenomenon of manual forgetting or repeated cleaning. At the same time, there is a lack of intelligent control, and it is difficult to accurately supply water according to actual soil moisture, light intensity and other factors, thereby reducing the drip irrigation effect.

[0006] Therefore, an efficient and intelligent solar-driven garden drip irrigation device is proposed. Summary of the Invention

A sound emission unit is installed on one valve body of the electric glasses valve A810, and a sound receiving unit is installed on one valve body of the electric glasses valve B820. By closing the valves 700 on the water diversion pipe A412, the drainage pipe A413, the water diversion pipe B422, the drainage pipe B423, the flushing pipe 510 and the miscellaneous pipe 530, and controlling the electric glasses valve A810 and the electric glasses valve B820, the valve bodies with the sound emission unit and the sound receiving unit are placed in the In the pipeline, the sound emitting unit emits a pulse wave at this time, and the sound receiving unit captures the pressure signal and transmits the signal to the intelligent control module. The data processing unit performs blockage analysis based on the sound signal. The signal is first collected by sampling every 10,000 data points. The original signal is then low-pass filtered, and a time-pulse wave dynamic pressure time domain diagram is drawn. Finally, waveform analysis can be used to determine whether the pipeline is blocked and calculate the blockage location. When it is determined that the pipeline is blocked, the valve 700 on the flushing pipe 510, the drainage pipe 530, and the water inlet pipe of the water pump 210 are immediately controlled to open, and the filter screen A414 and the filter screen B424 are flushed with a pressure twice that of the normal water pressure to flush away impurities on the filter screen A414 and the filter screen B424.

[0063] After the impurities are discharged and the system is unblocked, the filter boxes A411 and B421 are monitored again to obtain real-time detection values, which are input into the intelligent control module. The intelligent control module compares the real-time detection values ​​with the set values ​​again to determine whether they are normal. After returning to normal, the pipeline begins to automatically recover and work normally.

The irrigation decision-making algorithm integrates meteorological forecast data to establish a water demand prediction model based on the LSTM neural network. The model input includes the precipitation forecast for the next 24 hours, the estimated evaporation value and the plant transpiration coefficient. It can give priority to rainwater resources and dynamically mix solar energy to drive water sources. The tilt compensation algorithm can eliminate false operations caused by instantaneous cloud cover; the environmental perception module integrates soil moisture sensors, light sensors and temperature sensors; the energy storage unit adopts a hybrid energy storage structure of lithium-ion batteries and supercapacitors, and is equipped with a dynamic power allocation module. The dynamic power allocation module realizes real-time optimization of the charging and discharging strategy according to the light intensity prediction model; the LoRa wireless communication module is used for real-time monitoring data upload, remote irrigation strategy adjustment, fault diagnosis information push and equipment group collaborative control.

[0065] The dynamic water quantity control equation is embedded in the irrigation decision algorithm to optimize the synergistic relationship between irrigation quantity and solar power supply. The dynamic water quantity control equation is expressed as:

[0066]

[0067] in:

[0068] Q irr (t) is the irrigation flow rate at time t (L / h);

[0069] S(t) is the real-time light intensity (W / m 2 );

[0070] η pv is the efficiency of solar photovoltaic panels (%);

[0071] P max is the peak power of the photovoltaic panel (W);

[0072] E bat (t) is the remaining capacity of the energy storage unit (kWh);

[0073] ΔH(t) is the soil moisture deviation (the difference between the current humidity and the target humidity, %);

[0074] τ is the humidity response coefficient (dimensionless, default 0.5);

[0075] W pred (t) is the water demand (L) for the next 24 hours predicted based on the LSTM model;

[0076] C soil is the soil water holding capacity (L / m 3 );

[0077] α and β are weight coefficients, which are obtained by training with historical data and satisfy \alpha+\beta=1α+β=1.

[0078] Example:

[0079] When the light intensity S(t)=800W / m 2 , photovoltaic efficiency η pv =18%, energy storage capacity E bat (t) = 2 kWh, soil moisture deviation ΔH(t) = 10%, predicted water demand W pred When (t) = 50L, α = 0.6, and β = 0.4:

[0080]

[0081] Parameter Description:

[0082] The light intensity and photovoltaic parameters dynamically adjust the irrigation flow to ensure that the real-time power generation is prioritized when there is sufficient solar energy;

[0083] Soil moisture deviations amplify emergency irrigation needs through a logarithmic function;

[0084] LSTM predicts water demand and combines it with soil water holding capacity to balance long-term and short-term irrigation goals.

[0085] Technical effects:

[0086] 1. Energy-water synergy optimization: Dynamically adjust irrigation intensity based on real-time sunlight and energy storage status, reducing dependence on the power grid and improving solar energy utilization;

[0087] 2. Accurately respond to environmental changes: Soil moisture deviations are integrated with weather forecast data to avoid over-irrigation or under-irrigation;

[0088] 3. Extend equipment life: Smooth flow control reduces mechanical losses caused by frequent start and stop of the water pump.

[0089] The working principle of the dynamic water control equation is as follows:

[0090] 1. Data collection: The environmental perception module obtains S(t) and ΔH(t) in real time, and the energy storage module feeds back E bat (t);

[0091] 2. Prediction calculation: LSTM model output W pred (t), combining meteorological data with historical irrigation records;

[0092] 3. Equation solution: Substitute into the dynamic water flow control equation to calculate the optimal Q irr( t);

[0093] 4. Execution and control: The intelligent control module adjusts the pump power and valve opening to achieve precise flow matching.

[0094] This dynamic water control equation combines solar power supply efficiency, energy storage status and soil water demand through logarithmic functions and linear weighting, breaking through the limitations of traditional linear models. The coefficients α and β are dynamically optimized based on machine learning to adapt to different seasons and plant growth stages. bat When (t) falls below a threshold, the equation automatically reduces the α weight and switches to water-saving mode. This equation is specifically designed for multi-objective optimization of solar-driven drip irrigation systems, significantly improving resource utilization efficiency and system robustness.

[0095] Working principle:

[0096] Solar power supply: Solar photovoltaic panels 610 are used to convert solar energy into electrical energy. The energy storage unit stores the electrical energy converted by the solar photovoltaic panels 610 during the day, ensuring that the efficient and intelligent solar-driven garden drip irrigation device can still operate normally in conditions of insufficient light, such as at night or on cloudy days. The energy storage unit supplies power to various electrical components. The light intensity sensor detects the light intensity in the space and transmits the light intensity data to the intelligent control module. The intelligent control module receives the data and controls the operation of stepper motor A624 and stepper motor B626, so that the output shaft of stepper motor A624 drives the motor box B625, stepper motor B626, mounting frame 622 and solar photovoltaic panel 610 to rotate in the vertical direction. The output shaft of stepper motor B626 drives the mounting frame 622 and solar photovoltaic panel 610 to rotate in the horizontal direction until the solar photovoltaic panel 610 is adjusted to a spatial position perpendicular to the sunlight. The angle of the solar photovoltaic panel 610 can then be automatically adjusted according to different time periods and seasons to keep the solar photovoltaic panel 610 in the optimal light collection state and maximize the absorption of solar energy.

[0097] Water storage: When it is not raining, open the valves 700 on the water supply pipe A412 and the drainage pipe A413, allowing the water in the water supply pipe to be transported to the filter box A411 through the water supply pipe A412. After being filtered by the filter screen A414 in the filter box A411, the water flows through the connecting pipe 520 and the drainage pipe A413 into the cavity B on the left for storage;

[0098] When it rains, rainwater falls into the frame 310 and is filtered through the serpentine filter 370 to remove leaves, petals, etc., thus preventing the water pipe 330 from being blocked. The valves 700 on the water pipe B422 and the drain pipe B423 are opened, allowing the rainwater to be transported to the filter box B421 through the water pipe 330 and the water pipe B422 in sequence. After being filtered by the filter screen B424 in the filter box B421, the rainwater flows into the cavity B on the left side through the connecting pipe 520 and the drain pipe B423 for storage.

[0099] Self-cleaning: Close the valves 700 on the water diversion pipe A412, the drainage pipe A413, the flushing pipe 510, and the drainage pipe 530, and control the electric glasses valve A810 on the water diversion pipe A412 and the electric glasses valve B820 on the drainage pipe A413, so that the valve body of the electric glasses valve A810 with the sound emission unit is placed in the water diversion pipe A412, and the valve body of the electric glasses valve B820 with the sound receiving unit is placed in the drainage pipe A413. At this time, the sound emission unit emits a pulse wave, and the sound receiving unit captures the pressure signal and transmits the signal to the intelligent control module. The data processing unit performs blockage analysis based on the sound signal. First, the signal is collected by sampling every 10,000 data points. Then, the original signal is low-pass filtered, and a time-pulse wave dynamic pressure time domain diagram is drawn. Finally, the waveform analysis can be used to determine whether the pipeline is blocked and calculate the blockage location;

[0100] When it is determined that the pipeline is blocked, the valve 700 on the flushing pipe 510, the drainage pipe 530 and the water inlet pipe of the water pump 210 is immediately controlled to open, so that the water pump 210 extracts the water in the cavity B on the left and enters the filter box A411 in sequence through the water pump 210, the flushing pipe 510, and the connecting pipe 520. The filter screen A414 is flushed with a pressure twice higher than the normal water pressure to flush the impurities on the filter screen A414. The impurities are accumulated on the top of the drainage pipe 530 under the guidance of the water guide seat B430 in the filter box A411. The valve 700 on the drainage pipe 530 is opened, so that the impurities fall into the collecting drum 540 through the drainage pipe 530. The flushing water flows back to the cavity B on the left through the water hole 550 for collection. After the impurities are discharged and unblocked, the filter box A411 is monitored again to obtain real-time detection values, which are transmitted to the intelligent control module. The intelligent control module compares the real-time detection values ​​with the set values ​​again to determine whether they are normal. After returning to normal, the pipeline begins to automatically recover and work normally. Subsequently, the sealing door 140 is removed, the collecting cylinder 540 is unscrewed, and the impurities in it are dumped out to complete the self-cleaning of the filter screen A414. Similarly, the self-cleaning operation of the filter screen B424 can be achieved according to the above steps.

[0101] Zoned irrigation: Open the valves 700 on the water inlet pipe of the water pump 210, the drip irrigation pipe 230, and the connecting pipe 240 to use the water pump 210 to extract water from the cavity B on the left. The water is then transported to the pressure-compensating dripper 250 through the water pump 210, the water pipe 220, the drip irrigation pipe 230, and the connecting pipe 240. Finally, the water is directed by the hose 260 to each dripping arrow 270 to provide the plants with the required water and nutrients.

[0102] Intelligent irrigation: Soil moisture sensors, light sensors, and temperature sensors collect garden soil and environmental information in real time and transmit the data to the intelligent control module. The intelligent control module uses preset algorithms and models, combined with the growth stage and water demand patterns of the plants, to accurately calculate the irrigation amount and time, realizing intelligent precision drip irrigation.

However, it should be understood that the present invention is not limited to the above specific embodiments. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to implement different technical solutions.
