Description

Technical Field

[0001] This invention relates to the field of water cycle irrigation technology, and more specifically, to a sensor-based garden water cycle irrigation system. Background Technology

[0002] Garden irrigation is a technical measure to replenish the soil moisture needed for the growth of garden plants, thereby improving their growing conditions. It not only meets the water needs of garden plants, but also regulates the humidity and temperature of the garden air, washes dust off the plants, and beautifies the garden landscape.

[0003] Traditional irrigation methods primarily involve surface flooding, where water is drawn using simple irrigation tools such as rubber hoses and water trucks and delivered to the soil surface for plant absorption through surface runoff. This traditional irrigation method wastes a lot of water, easily causes soil erosion and salinization, is detrimental to normal plant growth, and does not meet the basic requirements for building water-saving landscaping.

[0004] To address these issues, water-saving irrigation technology is now the primary method: using specialized equipment to spray pressurized water into the air, which then falls onto the soil surface by gravity for plants to absorb.

[0005] While the two irrigation methods mentioned above can effectively irrigate, some irrigation water is still scattered around the garden plants, resulting in water waste. Furthermore, during irrigation, different garden plants have different growth patterns. For example, some plants are upright, growing vertically upwards without spreading outwards, while others are spreading outwards. Therefore, the corresponding irrigation methods will differ. If the same irrigation angle is used without adaptation, not only will the irrigation effect be greatly reduced, but some areas may even be unable to be irrigated, further increasing water waste.

[0006] To address the aforementioned issues, there is an urgent need for a sensor-based garden water circulation irrigation system. Summary of the Invention

[0007] The purpose of this invention is to provide a sensor-based garden water circulation irrigation system to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, a sensor-based garden water circulation irrigation system is provided, including a control terminal, a water level monitoring module, a monitoring data statistics module, an irrigation efficiency model simulation module, and an irrigation status matching module. The control terminal is used to control the spraying status of the spraying area and the working status of the bottom water recovery device. It is equipped with a steering sensor and a pressure sensor. The steering sensor obtains the irrigation angle of the spraying area, and the pressure sensor monitors the pressure status of the bottom water recovery device in real time, indirectly providing feedback on the amount of water recovered. The water level monitoring module is equipped with a camera monitoring instrument to acquire the water volume status information of the spray area in real time and transmit the water volume status information to the control terminal. The monitoring data statistics module is used to summarize the pressure status of the bottom water recovery device, the irrigation angle of the spray zone, the amount of water recovered, and the water volume status of the spray zone within a unit monitoring time, and generate monitoring data. The irrigation efficiency model simulation module combines monitoring data to establish an irrigation efficiency model and obtain the relationship between the irrigation angle of the sprinkler area, the water volume status information of the sprinkler area, and the amount of water recovered. The irrigation status matching module combines the irrigation efficiency model with the actual demand for garden plants to match the irrigation angle of the corresponding sprinkler area for different types of garden plants.

[0009] As a further improvement to this technical solution, the method for real-time monitoring of the pressure state of the bottom water recovery device through the pressure sensor in the control terminal includes the following steps: SA1. The pressure of the spray water under non-recovered conditions is obtained through a pressure sensor and marked as the initial pressure value. ; SA2. Establish the unit monitoring time and obtain the initial spraying time point for the unit monitoring time. and the time to end the spraying ; SA3. Obtain the spraying speed and unit spraying volume of the spraying water in the spraying zone, and obtain the time taken for the spraying water to reach the bottom water recovery device from the spraying zone, marking it as the reserved interval time. ; SA4, Define the stop monitoring time point of the pressure sensor. =Stop spraying time + Reserved interval time And obtain the current time point when monitoring stops. The pressure data obtained by the corresponding pressure sensor.

[0010] As a further improvement to this technical solution, the method for obtaining the irrigation angle of the spray zone through the steering sensor in the control terminal includes the following steps: SA5, obtains the initial spray angle of the spray zone through the steering sensor. And obtain the initial pressure data at the current angle through a pressure sensor; SA6. Obtain steering direction and define unit steering angle. The pressure sensor obtains the unit steering angle for each superposition. The corresponding pressure data; SA7 summarizes the pressure data from each monitoring process.

[0011] As a further improvement to this technical solution, the irrigation efficiency model simulation module includes a monitoring data classification and processing unit and an efficiency simulation diagram matching unit. The monitoring data classification and processing unit is used to classify and process the pressure data obtained by the pressure sensor, the irrigation angle of the sprinkler area, and the water volume status information. The efficiency simulation diagram matching unit establishes an efficiency simulation diagram corresponding to each irrigation angle according to the classification results.

[0012] As a further improvement to this technical solution, the irrigation efficiency model simulation module also includes an external factor condition acquisition unit, which acquires external factors affecting the irrigation status in accordance with the garden irrigation industry standards.

[0013] As a further improvement to this technical solution, the external factors in the external factor condition acquisition unit include wind force level and temperature range.

[0014] As a further improvement to this technical solution, the method for establishing an irrigation efficiency model in the irrigation efficiency model simulation module includes the following steps: SD1. Obtain the range of external factors during the monitoring process through local meteorological data, and conduct statistical analysis of monitoring data within the same range of external factors. SD2. The efficiency simulation diagram matching unit establishes efficiency simulation diagrams corresponding to each irrigation angle according to the classification results. SD3, compare the values ​​in the efficiency simulation graph.

[0015] As a further improvement to this technical solution, the spray area in the control terminal includes a water storage tank and an irrigation component installed at the bottom of the water storage tank. The bottom of the irrigation component is provided with several nozzles. The nozzles are rotatably connected to the irrigation component, and the steering sensor is installed at the connection position between the nozzles and the irrigation component to obtain the steering angle of the nozzles in real time. The bottom recovery device in the control terminal includes a recovery bin for recovering spray water and a filter plate installed at the top opening of the recovery bin. The filter plate is used to filter the spray water and is pre-embedded at the connection between two adjacent garden plants. A fixed chamber is fixedly installed at the bottom of the recycling bin, and a fixed valve is fixedly installed at the top opening of the fixed chamber. The top of the fixed valve extends into the inner end of the recycling bin and seals the bottom of the filter plate by contacting the inner wall of the recycling bin. This forms a conical chamber with the inner wall of the filter plate for pre-storing the recycled spray water. The recycling bin moves up and down along the outside of the fixed valve, and a reset component is connected between the bottom and top of the outer side of the recycling bin. Under the action of the reset component, the position of the recycling bin remains unchanged in the empty storage state. A pressure sensor is installed at the connection between the bottom and top of the outer side of the recycling bin to obtain the increase in pressure of the recycling bin in real time. Pipes are provided on both sides of the fixed valve. When the pressure generated by the spray water recovered at the inner end of the recovery chamber overcomes the reaction force applied to the recovery chamber by the reset component, the recovery chamber containing the spray water will move downward along the outside of the fixed valve, and a passage is formed between the inner wall of the bottom end and the two sides of the fixed valve. The two pipes are respectively connected to the two passages, and the spray water recovered at the inner end of the conical cavity is introduced into the inner end of the fixed chamber. A liquid pump is provided on the outside of the fixed chamber, and a recovery pipe is connected between the liquid pump and the water storage tank. The liquid pump draws the spray water at the inner end of the fixed chamber to the inner end of the water storage tank.

This model obtains information on the relationship between the irrigation angle and water volume status of the sprinkler area, as well as the amount of water recovered. Simultaneously, a irrigation status matching module, combined with the irrigation efficiency model and the actual needs of garden plants, matches the corresponding irrigation angle of the sprinkler area to different types of garden plants. This not only allows for the recycling of wasted sprinkler water through a bottom water recovery device, reducing water waste, but also, with real-time data feedback from different sensors, obtains the relationship between the irrigation angle of the sprinkler area and the amount of water wasted. This allows for the matching of the optimal irrigation angle for different types of garden plants, further improving irrigation efficiency and reducing water waste. Attached Figure Description

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Please see Figure 1 As shown, a sensor-based garden water circulation irrigation system is provided, including a control terminal A, a water level monitoring module B, a monitoring data statistics module C, an irrigation efficiency model simulation module D, and an irrigation status matching module E. Among them, the control terminal A is used to control the spraying status of the spraying area and the working status of the bottom water recovery device. It is equipped with a steering sensor and a pressure sensor. The steering sensor obtains the irrigation angle of the spraying area, and the pressure sensor monitors the pressure status of the bottom water recovery device in real time, indirectly providing feedback on the amount of water recovered. The water level monitoring module B is equipped with a camera monitoring instrument to acquire the water volume status information of the sprinkler area in real time and transmit the water volume status information to the control terminal A. The monitoring data statistics module C is used to summarize the pressure status of the bottom water recovery device, the irrigation angle of the spray zone, the amount of water recovered, and the water volume status of the spray zone within a unit monitoring time, and generate monitoring data. The irrigation efficiency model simulation module D combines monitoring data to establish an irrigation efficiency model and obtain the relationship between the irrigation angle of the sprinkler area, the water volume status of the sprinkler area, and the amount of water recovered. The irrigation status matching module E combines the irrigation efficiency model with the actual demand of garden plants to match the irrigation angle of the corresponding sprinkler area for different types of garden plants.

[0022] In practical use, during garden irrigation, the bottom water recycling device is pre-buried between adjacent garden plant areas. The spray area is installed above the garden plant area and sprays downwards. In order to adapt to the irrigation of different garden plants, the spray angle of the spray area is obtained in real time through the steering sensor configured in the control terminal, and the water storage status of the spray area is obtained in real time through the water level monitoring module B. During the spraying process, some spray water is sprayed onto the surface of the plants, some spray water drips onto the soil around the plants, and some spray water will enter the bottom water recycling device for recycling. To further analyze the data, the monitoring data statistics module C summarizes information on the pressure state of the bottom water recovery device, the irrigation angle of the sprinkler zone, the recovered water volume, and the water volume status of the sprinkler zone within a unit monitoring time, generating monitoring data. Then, the irrigation efficiency model simulation module D, combined with the monitoring data, establishes an irrigation efficiency model to obtain the relationship between the irrigation angle of the sprinkler zone, the water volume status of the sprinkler zone, and the recovered water volume. Specifically, the recovered water volume represents the amount of wasted sprinkler water in the sprinkler zone, while the sprinkler water sprayed onto the surface of the garden plants and the soil represents the amount of sprinkler water utilized. This can be analyzed by comparing the water volume in the sprinkler zone with the recovered water volume. The difference in water volume is estimated, and these are all related to the irrigation angle of the sprinkler area. Therefore, the irrigation state matching module E, combined with the irrigation efficiency model and the actual demand of garden plants, is used to match the corresponding irrigation angle of the sprinkler area for different types of garden plants. This not only allows the wasteful sprinkler water to be recycled and treated through the bottom water recycling device, reducing water waste, but also, with the real-time data feedback from different sensors, obtains the relationship between the irrigation angle of the sprinkler area and the amount of water waste, matching the optimal irrigation angle of the sprinkler area for different types of garden plants, further improving irrigation effect and reducing water waste.

[0023] In addition, such as Figure 6 As shown, the method for real-time monitoring of the pressure state of the bottom water recovery device in control terminal A via a pressure sensor includes the following steps: SA1. The pressure of the spray water under non-recovered conditions is obtained through a pressure sensor and marked as the initial pressure value. ; SA2. Establish the unit monitoring time and obtain the initial spraying time point for the unit monitoring time. and the time to end the spraying ; SA3. Obtain the spraying speed and unit spraying volume of the spraying water in the spraying zone, and obtain the time taken for the spraying water to reach the bottom water recovery device from the spraying zone, marking it as the reserved interval time. ; SA4, Define the stop monitoring time point of the pressure sensor. =Stop spraying time + Reserved interval time And obtain the current time point when monitoring stops. The pressure data obtained by the corresponding pressure sensor.

[0024] In practical use, during the pressure monitoring of the bottom water recovery device, in order to improve the accuracy of pressure data feedback, the pressure of the unrecovered spray water is first obtained through the pressure sensor and marked as the initial pressure value. That is, the self-weight in the empty state, and the initial spraying time point of the unit monitoring time is obtained by defining the unit monitoring time. and the time to end the spraying Since some spray water remains sprayed after the spraying zone ends and does not fall into the bottom water recovery device, it is necessary to obtain the spraying speed and unit spray volume of the spray water in the spraying zone, i.e., the spraying speed at different times when the spraying will end. The time taken for the spray water to travel from the spray zone to the bottom water recovery device, which is used as the stop monitoring point of the pressure sensor, is recorded as the reserved interval time. Finally, the stopping monitoring time point of the pressure sensor is obtained. =Stop spraying time + Reserved interval time This is because the data acquired by the pressure sensor changes in real time. To reduce errors, it is necessary to allow time for the spray water to fall and to obtain the current point at which monitoring stops. The pressure data obtained by the corresponding pressure sensor can improve the accuracy of the pressure sensor's monitoring data and reduce monitoring errors.

[0025] Furthermore, such as Figure 7 As shown, the method for obtaining the irrigation angle of the sprinkler zone through the steering sensor in control terminal A includes the following steps: SA5, obtains the initial spray angle of the spray zone through the steering sensor. And obtain the initial pressure data at the current angle through a pressure sensor; SA6. Obtain steering direction and define unit steering angle. The pressure sensor obtains the unit steering angle for each superposition. The corresponding pressure data; SA7 summarizes the pressure data from each monitoring process.

[0026] In the process of obtaining the irrigation angle, the initial spraying angle of the sprinkler area must first be obtained through the steering sensor. After spraying for the same period of time, the initial pressure data fed back by the pressure sensor at the corresponding time point is obtained. Since the spraying area is located directly above the garden plants and the bottom water recovery device, it is necessary to ensure that the spraying equipment in the spraying area can be adjusted horizontally during the spraying process. The corresponding adjustment direction needs to be determined in advance, and the unit turning angle is defined. The pressure sensor obtains the unit steering angle for each superposition. The corresponding pressure data is that each time the same unit steering angle is increased. Afterwards, the corresponding pressure data is obtained, and finally the data is summarized as a reference for matching the optimal steering angle in the later stage.

[0027] Furthermore, such as Figure 2As shown, the irrigation efficiency model simulation module D includes a monitoring data classification and processing unit D1 and an efficiency simulation diagram matching unit D2. The monitoring data classification and processing unit D1 is used to classify and process the pressure data obtained by the pressure sensor, the irrigation angle of the sprinkler area, and the water volume status information. The efficiency simulation diagram matching unit D2 establishes the efficiency simulation diagram corresponding to each irrigation angle according to the classification results.

[0028] The irrigation efficiency model simulation module D also includes an external factor condition acquisition unit D3, which, in conjunction with the garden irrigation industry standards, acquires the external factors that affect the irrigation status.

[0029] The external factors in the external factor condition acquisition unit D3 include wind force level and temperature range.

[0030] like Figure 8 As shown, the method for establishing an irrigation efficiency model in the irrigation efficiency model simulation module D includes the following steps: SD1. Obtain the range of external factors during the monitoring process through local meteorological data, and conduct statistical analysis of monitoring data within the same range of external factors. SD2: The efficiency simulation diagram matching unit D2 is used to establish the efficiency simulation diagram corresponding to each irrigation angle according to the classification results. SD3, compare the values ​​in the efficiency simulation graph.

[0031] In the process of establishing the irrigation efficiency model, the pressure data obtained by the pressure sensor, the irrigation angle of the sprinkler area, and the water volume status information are first classified and processed by the monitoring data classification and processing unit D1. Since the irrigation process is affected by the environment, such as the wind level, the stronger the wind, the greater the offset of the irrigation water, and the lower the corresponding spraying effect. At this time, it is necessary to adjust the turning angle so that the spray water can overcome the wind and maximize the spraying of the water onto the surface of the garden plants. Therefore, the external factor condition acquisition unit D3 needs to combine the garden irrigation industry standards to obtain the external factors that affect the irrigation status. The external factors involved in this invention include wind level and temperature range. The efficiency simulation diagram matching unit D2 is used to create efficiency simulation diagrams for each irrigation angle according to the classification results. During the creation process, it is necessary to ensure that the numerical ranges of external factors are the same. Figures 4-5 As shown, Figure 4 This refers to the total amount of water poured into the spray zone at the initial turning angle (i.e., the initial spraying time point). Until the end of the spraying time The total amount of water consumed by the spraying in the spray area during the time period), and the amount of water recovered by the bottom water recovery device (i.e., the amount of water recovered by the bottom water recovery device at the time when monitoring stops). The pressure data displayed at that time, combined with the initial pressure value. The water volume is converted into recycled water volume) and the total irrigation volume of the sprinkler area (i.e., the total irrigation volume of the sprinkler area - the water volume recycled by the bottom water recovery device), and the corresponding water volume values ​​are respectively , as well as , Figure 5 The initial turning angle is superimposed with the total irrigation volume of the sprinkler zone, the water volume recovered by the bottom water recovery device, and the total irrigation volume of the sprinkler zone under the condition of a unit turning angle. The corresponding water volume values ​​are as follows: , as well as Since the external factors corresponding to the two turning angles are the same—wind force level 0-2 and temperature range 16-20℃—they can be compared as similar data. The comparison shows that after superimposing a unit turning angle, the total irrigation volume of the corresponding sprinkler area exceeds that of the initial turning angle. > The higher the total amount of water irrigated in the sprinkler area, the higher the irrigation utilization rate.

[0032] It is worth noting that the optimal turning angle varies depending on the external factors. Therefore, it is necessary to consider the water demand of garden plants under the current external conditions. This solution not only recycles excess water from irrigation through a bottom water recycling device, but also provides feedback on the utilization effect of the water through the amount of water recycled. By adjusting the turning angle, the optimal spraying turning angle can be matched under different external conditions.

[0033] In addition, the sprinkler area in control terminal A includes a water storage tank 10 and an irrigation component 110 installed at the bottom of the water storage tank 10. Several nozzles are provided at the bottom of the irrigation component 110. The nozzles are rotatably connected to the irrigation component 110. A steering sensor is installed at the connection between the nozzle and the irrigation component 110 to obtain the steering angle of the nozzle in real time. The bottom recovery device in control terminal A includes a recovery chamber 20 for recovering the sprinkler water and a filter plate 210 installed at the top opening of the recovery chamber 20. The filter plate 210 is used to filter the sprinkler water. The filter plate 210 is embedded in the connection between two adjacent garden plants. A fixed chamber 30 is fixedly installed at the bottom of the recovery chamber 20. A fixed valve 310 is fixedly installed at the top opening of the fixed chamber 30. The top of the fixed valve 310 extends into the inner end of the recovery chamber 20 and seals the bottom of the filter plate 210 by contacting the inner wall of the recovery chamber 20. It forms a conical chamber with the inner wall of the filter plate 210 for pre-storing the recovered spray water. The recovery chamber 20 moves up and down along the outside of the fixed valve 310. A reset component is connected between the bottom and top of the outer side of the recovery chamber 20. Under the action of the reset component, the position of the recovery chamber 20 in the empty storage state remains unchanged. A pressure sensor is installed at the connection between the bottom and top of the outer side of the recovery chamber 20 to obtain the increase in pressure of the recovery chamber 20 in real time. Pipes are provided on both sides of the fixed valve 310. When the pressure generated by the spray water recovered at the inner end of the recovery chamber 20 overcomes the reaction force applied to the recovery chamber 20 by the reset component, the recovery chamber 20 containing the spray water will move downward along the outside of the fixed valve 310, and a passage is formed between the inner wall of the bottom end and the two sides of the fixed valve 310. The two pipes are respectively connected to the two passages, and the spray water recovered at the inner end of the conical cavity is introduced into the inner end of the fixed chamber 30. A liquid pump 320 is provided on the outside of the fixed chamber 30, and a recovery pipe 330 is connected between the liquid pump 320 and the water storage tank 10. The spray water at the inner end of the fixed chamber 30 is drawn away to the inner end of the water storage tank 10 by the liquid pump 320.

[0034] In practical use, during irrigation, the valves of each water storage tank 10 and each nozzle are first opened via control terminal A, and spray water outward through the nozzles. At this time, some of the spray water is sprayed onto the surface of the garden plants, and some of the spray water drips into the soil around the garden plants. The remaining spray water is filtered by filter plate 210 and drips into the inner end of the recovery chamber 20. In the initial state, under the action of the reset component, which can be implemented by a spring, the reaction force applied to the recovery chamber 20 keeps the position of the recovery chamber 20 unchanged. The pressure increase of the recovery chamber 20 is obtained in real time through a pressure sensor. Until the irrigation work is completed, the irrigation efficiency at the current turning angle is obtained through the pressure data of the pressure sensor and the nozzle turning angle fed back by the turning sensor. After multiple irrigations, the spray water inside the recovery chamber 20 accumulates more and more, and the corresponding pressure increases to the point that it can overcome the reaction force applied by the reset component. At this time, the recovery chamber 20 will move down along the outside of the fixed valve 310 and the channel between it and the outside of the fixed valve 310 will guide the recovered spray water into the inside of the fixed chamber 30. Finally, the liquid pump 320 and the recovery pipe 330 will pump the recovered spray water into the inside of the water storage tank 10 for secondary reuse.
