Description

Technical Field

[0001] This invention patent relates to the technical field of farmland irrigation, and more specifically, to a method for intelligent monitoring of farmland irrigation water use. Background Technology

[0002] In the field of farmland irrigation technology, accurate monitoring of irrigation water is of vital importance for improving water resource utilization efficiency, ensuring crop growth, and achieving sustainable agricultural development. However, in the actual monitoring of farmland irrigation water, it is often susceptible to interference from external factors, resulting in poor accuracy of water level monitoring.

[0003] In the existing technology, traditional methods for monitoring farmland irrigation water are often prone to shaking or shifting when encountering fast water flow, especially near the outlet of some large irrigation channels or sprinkler and drip irrigation systems, resulting in inaccurate water level measurements. Moreover, farmland irrigation water often contains mud, sand, weeds and other debris, which can easily enter the working area of ​​the water level sensor and interfere with or block it, thereby hindering the normal flow of water and the transmission of water level, making the water level sensor unable to accurately reflect the actual water level data. In addition, the debris may also get tangled on these components and cause damage. Furthermore, existing moisture and water level data are monitored and transmitted independently by different sensors, which makes data integration difficult when conducting comprehensive analysis of farmland irrigation water use, affecting the scientific rigor and accuracy of irrigation water use decisions. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent monitoring method for farmland irrigation water, which aims to solve the problem that the accuracy of farmland irrigation water monitoring is poor due to interference during the monitoring process in the prior art.

[0005] This invention is implemented as follows: a smart monitoring method for farmland irrigation water includes the following steps: 1) Insert multiple moisture sensors into the farmland soil, the moisture sensors monitor the moisture data of the farmland soil, and the moisture sensors are electrically connected to the controller; 2) Multiple fixing plates are arranged on the farmland soil, and the fixing plates are horizontally fixed on the farmland soil; the fixing plates are provided with a longitudinally arranged rotating cylinder made of transparent material, the rotating cylinder is eccentrically connected to the fixing plates, and the rotating cylinder has a cavity. The outer periphery of the rotating cylinder has multiple strip-shaped connecting holes, the bottom of which extends to the bottom of the cylinder cavity and the top of which extends to the upper part of the cylinder cavity; a strip-shaped longitudinally arranged water level sensor is provided in the cylinder cavity, the water level sensor monitors the water level data of the water body on the farmland soil, and the water level sensor is electrically connected to the controller. A wire mesh tube is fitted around the outer periphery of the rotating cylinder. The wire mesh tube is arranged around the outer periphery of the rotating cylinder and has an annular gap with the rotating cylinder. The top of the wire mesh tube extends above the connecting hole and is rotatably connected to the rotating cylinder. The bottom of the wire mesh tube is movably abutted against the fixed plate. 3) The water on the farmland water body passes through the wire mesh cylinder and the connecting hole in sequence and enters the cylinder cavity until the water level of the farmland soil is level with the water level of the water in the cylinder cavity. The water level sensor monitors the water level data of the water in the cylinder cavity. As the water flows through the wire mesh tube and the connecting holes, it drives the wire mesh tube to rotate relative to the rotating cylinder, and drives the rotating cylinder to rotate eccentrically relative to the fixed plate. 4) The moisture sensor transmits moisture data to the controller, the water level sensor transmits water level data to the controller, and the controller transmits moisture data and water level data to the control center via wireless communication to monitor the moisture and water level of the farmland soil.

[0006] Furthermore, in step 1), multiple moisture sensors are arranged at intervals around the circumference of the farmland, and each moisture sensor is inserted into the farmland soil at different depths.

[0007] Furthermore, in step 2), the connecting hole is arranged in a curved shape along the height direction of the cylindrical cavity.

[0008] Furthermore, in step 2), the rotating cylinder is provided with a scale, which extends along the height of the rotating cylinder.

[0009] Furthermore, in step 2), a plurality of fixing pins are inserted into the fixing plate along the circumference of the fixing plate; the top of the fixing pin has a top head, the fixing pin has an upper section extending above the fixing plate and an insertion section penetrating into the farmland soil, the top head is disposed on the upper section, and an elastic ring made of elastic material is sleeved on the outer periphery of the upper section. After the insertion segment is fixedly inserted into the farmland soil, the bottom of the elastic ring abuts against the fixing plate, the top of the elastic ring abuts against the top head, and the elastic ring is in a compressed deformation state. The multiple fixing pins fix the fixing plate horizontally on the farmland soil.

[0010] Furthermore, in step 2), the outer periphery of the insertion segment has multiple outer rings made of elastic material, the multiple outer rings are arranged at intervals along the axial direction of the insertion segment, the outer rings are arranged around the circumference of the insertion segment, and the top of the outer ring has an upward-facing stepped ring surface; when the insertion segment is fixedly inserted into the farmland soil, the farmland soil abuts against the stepped ring surface from top to bottom.

[0011] Furthermore, in step 2), the outer periphery of the outer ring has an outwardly arranged outer peripheral side surface, and along the direction from top to bottom of the outer peripheral side surface, the outer peripheral side surface is arranged inwardly at an angle; the bottom of the outer peripheral side surface is fixedly connected to the outer periphery of the insertion section, and the top of the outer peripheral side surface is connected to the outer periphery of the stepped ring surface. The outer side of the stepped annular surface is connected to the outer peripheral side surface, and an annular hollow area is formed on the inner side of the stepped annular surface. The hollow area is arranged around the outer periphery of the insertion section, and the outer periphery of the insertion section is exposed in the hollow area. The outer ring is provided with an inclined channel, the lower end of which penetrates through the outer side surface and the upper end of which penetrates into the hollow area. Along the inclined channel from bottom to top, the inclined channel is arranged inward at an inward angle, and the diameter of the inclined channel gradually decreases. When the insertion section is fixedly inserted into the farmland soil, the farmland soil is embedded in the hollow area and the inclined channel, which compresses the outer ring to expand and deform outward.

[0012] Furthermore, in step 2), the top of the wire mesh cylinder is provided with an annular strip, which is arranged around the outer periphery of the rotating cylinder. The outer periphery of the rotating cylinder is provided with an annular groove, and the annular strip is movably placed in the annular groove. In step 3), when the wire mesh cylinder rotates relative to the rotating cylinder, the annular strip rotates along the annular groove.

[0013] Furthermore, in step 2), the bottom of the rotating cylinder has a bottom plate, and the fixed plate is provided with a convex shaft. The convex shaft passes through the bottom plate and is rotatably connected to the bottom plate, and the convex shaft is eccentrically arranged with respect to the bottom plate; in step 3), when the rotating cylinder rotates relative to the fixed plate, the rotating cylinder rotates eccentrically with respect to the convex shaft as the rotation center.

[0014] Furthermore, in step 2), the outer periphery of the wire mesh cylinder has multiple elastic strips, which are arranged at intervals along the axial direction of the wire mesh cylinder and staggered along the circumferential direction of the wire mesh cylinder; along the axial direction of the wire mesh cylinder, adjacent elastic strips are connected by floating strips, the density of the floating strips is less than the density of water, and the floating strips are arranged at an angle to the axial direction of the wire mesh cylinder. In step 3), as the water flows through the wire mesh tube and the connecting holes, the floating sleeve is oscillating due to changes in buoyancy. The elastic strip drives the wire mesh tube to rotate relative to the rotating cylinder, which in turn drives the rotating cylinder to rotate relative to the fixed plate.

[0015] Compared with existing technologies, the intelligent monitoring method for farmland irrigation water provided by this invention has the following outstanding technical advantages: 1) Utilizing the special structure of the wire mesh cylinder and the rotating cylinder, which are eccentrically connected and have an annular gap, when water flows in, it will drive the wire mesh cylinder and the rotating cylinder to rotate. This process can buffer the impact of the water flow and avoid the water level sensor from being directly impacted, thereby effectively reducing the fluctuation and error of water level data caused by the impact of the water flow, and greatly improving the accuracy of water level monitoring. 2) By setting up the wire mesh cylinder, impurities can be prevented from entering the connecting hole or the inside of the cylinder during water flow, thus preventing blockage. It also avoids impurities from getting tangled on the components of the monitoring device, ensuring that the water level sensor can work normally and continuously, stably and accurately monitor water level data. This makes up for the shortcomings of existing monitoring equipment that are easily interfered with by impurities, affecting the measurement accuracy and stability. 3) By inserting multiple moisture sensors into the farmland soil to monitor soil moisture data, and simultaneously setting up devices such as fixed plates and rotating cylinders on the soil to monitor water level data, the multi-sensor collaborative approach can comprehensively acquire relevant information on farmland irrigation water, from the internal soil moisture status to the water level changes of farmland surface water bodies, providing richer and more comprehensive data support for precision irrigation.

[0020] Reference Figure 1-4 The image shows a preferred embodiment of the present invention.

[0021] A smart monitoring method for farmland irrigation water includes the following steps: 1) Insert multiple moisture sensors 100 into the farmland soil. The moisture sensors 100 monitor the moisture data of the farmland soil. The moisture sensors 100 are electrically connected to the controller 101. 2) Multiple fixing plates 200 are arranged on the farmland soil, and the fixing plates 200 are horizontally fixed on the farmland soil; the fixing plates 200 are provided with a longitudinally arranged rotating cylinder 300 made of transparent material, the rotating cylinder 300 is eccentrically connected to the fixing plates 200, and the rotating cylinder 300 has a cylinder cavity 301. The outer periphery of the rotating cylinder 300 has multiple strip-shaped connecting holes 302. The bottom of the connecting holes 302 extends to the bottom of the cylinder cavity 301, and the top of the connecting holes 302 extends to the upper part of the cylinder cavity 301. A strip-shaped longitudinally arranged water level sensor 102 is provided in the cylinder cavity 301. The water level sensor 102 monitors the water level data of the water body on the farmland soil. The water level sensor 102 is electrically connected to the controller 101. A wire mesh tube 303 is fitted around the outer periphery of the rotating cylinder 300. The wire mesh tube 303 is arranged around the outer periphery 206 of the rotating cylinder 300 and has an annular gap 304 between it and the rotating cylinder 300. The top of the wire mesh tube 303 extends above the connecting hole 302 and is rotatably connected to the rotating cylinder 300. The bottom of the wire mesh tube 303 is movably abutted against the fixed plate 200. 3) The water on the farmland water body passes through the wire mesh cylinder 303 and the connecting hole 302 in sequence and enters the cylinder cavity 301 until the water level of the water on the farmland soil is level with the water level of the water in the cylinder cavity 301. The water level sensor 102 monitors the water level data of the water in the cylinder cavity 301. During the flow of water in the wire mesh cylinder 303 and the connecting hole 302, the wire mesh cylinder 303 is driven to rotate relative to the rotating cylinder 300, and the rotating cylinder 300 is driven to rotate eccentrically relative to the fixed plate 200. 4) Moisture sensor 100 transmits moisture data to controller 101, and water level sensor 102 transmits water level data to controller 101. Controller 101 transmits moisture data and water level data to the control center via wireless communication to monitor the moisture and water level of farmland soil.

[0022] The intelligent monitoring method for farmland irrigation water provided above has the following outstanding technical advantages: 1) Utilizing the special structure of the wire mesh cylinder 303 and the rotating cylinder 300, the two are eccentrically connected and have an annular gap 304. When water flows in, it will drive the wire mesh cylinder 303 and the rotating cylinder 300 to rotate. This process can buffer the impact of water flow and avoid the water level sensor 102 from being directly impacted, thereby effectively reducing the fluctuation and error of water level data caused by water flow impact and greatly improving the accuracy of water level monitoring. 2) By setting the wire mesh tube 303, impurities can be prevented from entering the connecting hole 302 or the tube cavity 301 during water flow, thus preventing blockage. It also avoids impurities from getting tangled on the components of the monitoring device, ensuring that the water level sensor 102 can work normally and continuously, stably and accurately monitor water level data. This makes up for the shortcomings of existing monitoring equipment that are easily interfered with by impurities, affecting measurement accuracy and stability. 3) By inserting multiple moisture sensors 100 into the farmland soil to monitor soil moisture data, and simultaneously setting up devices such as a fixed plate 200 and a rotating cylinder 300 on the soil to monitor water level data, the multi-sensor collaborative operation can comprehensively acquire relevant information on farmland irrigation water, from the internal soil moisture status to the water level changes of the farmland surface water, providing richer and more comprehensive data support for precision irrigation.

[0023] In this embodiment, in step 1), multiple moisture sensors 100 are arranged at intervals around the circumference of the farmland, and the depths to which each moisture sensor 100 is inserted into the farmland soil are different.

[0024] This allows for comprehensive monitoring of soil moisture conditions in farmland from multiple directions, avoiding inaccurate monitoring due to localized moisture differences. Furthermore, the different insertion depths of each moisture sensor enable stratified monitoring of soil moisture at different depths, providing a more accurate reflection of soil moisture distribution and offering more detailed moisture data support for precision irrigation.

[0025] In this embodiment, in step 2), the connecting hole 302 is arranged in a curved shape along the height direction of the cylindrical cavity 301.

[0026] This extends the path of water into the cylinder 301, gradually slowing down the flow rate as the water enters the cylinder 301. This reduces the direct impact of the water flow on the interior of the cylinder 301 and the water level sensor 102, effectively reducing water level data fluctuations and measurement errors caused by water flow impact, and improving the accuracy of water level monitoring.

[0027] In this embodiment, in step 2), a scale 305 is provided on the rotating cylinder 300, and the scale 305 extends along the height of the rotating cylinder 300.

[0028] This allows for a direct display of the water level changes within the cylinder 301, facilitating visual comparison and calibration of the measurement data from the water level sensor 102. This further improves the accuracy and reliability of water level monitoring and helps to promptly detect and correct any potential errors in the sensor.

[0029] In this embodiment, in step 2), a plurality of fixing pins 201 are inserted into the fixing plate 200 along the circumference of the fixing plate 200; the top of the fixing pin 201 has a top head 202, the fixing pin 201 has an upper section 203 extending above the fixing plate 200 and an insertion section 204 inserted into the farmland soil, the top head 202 is disposed on the upper section 203, and an elastic ring 205 made of elastic material is sleeved on the outer periphery of the upper section 203; After the insertion segment 204 is fixedly inserted into the farmland soil, the bottom of the elastic ring 205 abuts against the fixing plate 200, the top of the elastic ring 205 abuts against the top head 202, and the elastic ring 205 is in a compressed deformation state. Multiple fixing pins 201 fix the fixing plate 200 horizontally on the farmland soil.

[0030] The elastic ring 205 acts as a buffer and shock absorber, adapting to minor deformations and vibrations of the soil. It prevents the fixing pin 201 from loosening or being damaged due to external impact. Furthermore, the elasticity of the elastic ring 205 ensures a tight connection between the fixing pin 201 and the fixing plate 200, further enhancing the stability of the entire device. This ensures that the water level sensor 102 can operate stably during long-term use and improves the reliability of the monitoring data.

[0031] In this embodiment, in step 2), the outer periphery of the insertion segment 204 has multiple outer rings 206 made of elastic material. The multiple outer rings 206 are arranged at intervals along the axial direction of the insertion segment 204 and are arranged around the circumference of the insertion segment 204. The top of the outer ring 206 has an upward-facing stepped ring surface 207. When the insertion segment 204 is fixedly inserted into the farmland soil, the farmland soil abuts against the stepped ring surface 207 from top to bottom.

[0032] The outer ring 206 and the stepped annular surface 207 increase the contact area between the fixing pin 201 and the soil, improve the lateral constraint force of the soil on the fixing pin 201, enhance the pull-out resistance of the fixing pin 201, ensure the stability of the fixing pin 201 in the soil, and effectively prevent the fixing pin 201 from loosening due to external forces, thereby ensuring the stability of the entire device and the accuracy of water level monitoring.

[0033] In this embodiment, in step 2), the outer periphery of the outer ring 206 has an outwardly arranged outer periphery side 208, and along the direction from top to bottom of the outer periphery side 208, the outer periphery side 208 is arranged inwardly at an angle; the bottom of the outer periphery side 208 is fixedly connected to the outer periphery of the insertion section 204, and the top of the outer periphery side 208 is connected to the outer periphery of the stepped ring surface 207. The outer side of the stepped annular surface 207 is connected to the outer peripheral side surface 208, and an annular hollow area 209 is formed on the inner side of the stepped annular surface 207. The hollow area 209 is arranged around the outer peripheral ring 206 of the insertion section 204, and the outer periphery of the insertion section 204 is exposed in the hollow area 209. An inclined channel 210 is provided in the outer ring 206. The lower end of the inclined channel 210 penetrates the outer side 208, and the upper end of the inclined channel 210 penetrates to the hollow area 209. Along the direction of the inclined channel 210 from bottom to top, the inclined channel 210 is arranged inwardly, and the diameter of the inclined channel 210 gradually decreases. After the insertion segment 204 is fixedly inserted into the farmland soil, the farmland soil is embedded in the hollow area 209 and the inclined channel 210, which compresses the outer ring 206 to expand and deform outward.

[0034] On the one hand, the inclined arrangement of the outer peripheral side 208 helps to guide the soil to fill around the insertion section 204, so that the soil wraps the insertion section 204 more tightly, enhances the anchoring effect of the fixing pin 201, improves the stability of the device, and at the same time reduces the resistance of the soil to the insertion section 204, making it easier to install the fixing pin 201. On the other hand, the hollow area 209 on the inner side of the stepped annular surface 207 allows farmland soil to be embedded in the hollow area 209 and squeeze the outer ring 206 to expand and deform outward, making the fixing pin 201 more tightly bonded to the soil. The elastic reaction force of the outer ring 206 can enhance the friction between the fixing pin 201 and the soil, prevent the insertion section 204 from sliding in the soil, ensure the stability of the fixing plate 200, and thus improve the accuracy of water level monitoring.

[0035] Furthermore, during the process of inserting the fixing pin 201 into the farmland soil, the presence of the inclined channel 210 facilitates the embedding of the outer ring 206 into the farmland soil. The farmland soil is embedded in the inclined channel 210, which compresses the inclined channel 210 to expand and deform outward, so that the outer ring 206 is firmly inserted into the farmland soil.

[0036] In this embodiment, in step 2), the top of the wire mesh cylinder 303 is provided with an annular strip, which is arranged around the outer periphery 206 of the rotating cylinder 300. The outer periphery of the rotating cylinder 300 is provided with an annular groove, and the annular strip is movably placed in the annular groove. In step 3), when the wire mesh cylinder 303 rotates relative to the rotating cylinder 300, the annular strip rotates along the annular groove.

[0037] The combination of the annular bar and the annular groove guides and limits the rotation of the wire mesh cylinder 303, allowing it to rotate smoothly and steadily relative to the rotating cylinder 300 under the drive of water flow. This prevents the wire mesh cylinder 303 from shaking or shifting during rotation, ensuring stable and reliable relative motion between the wire mesh cylinder 303 and the rotating cylinder 300, and guaranteeing the normal operation of the monitoring device and the stability of the monitoring data.

[0038] In this embodiment, in step 2), the bottom of the rotating cylinder 300 has a bottom plate 306, and the fixed plate 200 is provided with a convex shaft 307. The convex shaft 307 passes through the bottom plate 306 and is rotatably connected to the bottom plate 306. The convex shaft 307 and the bottom plate 306 are eccentrically arranged. In step 3), when the rotating cylinder 300 rotates relative to the fixed plate 200, the rotating cylinder 300 rotates eccentrically with the convex shaft 307 as the rotation center.

[0039] The eccentric connection between the bottom plate 306 and the convex shaft 307 allows the rotating cylinder 300 to rotate eccentrically around the convex shaft 307 under the drive of water flow. This rotation of the rotating cylinder 300 creates a certain agitation effect on the water, which helps the water to be distributed more evenly in the cylinder cavity 301, avoiding local accumulation or poor flow of water in the cylinder cavity 301. This enables the water level sensor 102 to more accurately monitor the real water level of the farmland, improving the accuracy of water level monitoring.

[0040] In this embodiment, in step 2), multiple elastic strips 308 are arranged at intervals along the axial direction of the wire mesh cylinder 303 and staggered along the circumferential direction of the wire mesh cylinder 303; along the axial direction of the wire mesh cylinder 303, floating strips 309 are connected between adjacent elastic strips 308, the density of the floating strips 309 is less than the density of water, and the floating strips 309 are arranged at an angle to the axial direction of the wire mesh cylinder 303; In step 3), as the water flows through the wire mesh cylinder 303 and the connecting hole 302, the floating sleeve swings due to changes in buoyancy. The elastic strip 308 drives the wire mesh cylinder 303 to rotate relative to the rotating cylinder 300, which in turn drives the rotating cylinder 300 to rotate relative to the fixed plate 200.

[0041] In this way, the water flow can be regulated and buffered to a certain extent, reducing the direct impact of the water flow on the water level sensor 102. At the same time, the swinging of the elastic strip 308 and the floating strip 309 can also drive the water to form a small circulation flow in the cylinder 301, preventing the water from settling or stratifying in the cylinder 301. This ensures that the water level sensor 102 can continuously and accurately monitor the real water level of the farmland water body, thereby helping to solve the problem of poor accuracy caused by interference during the monitoring of farmland irrigation water.

[0042] The following section will provide a detailed, clear, and complete description of the aforementioned intelligent monitoring method for farmland irrigation water in practical applications, so as to make the implementation process of the intelligent monitoring method for farmland irrigation water easier to understand.

[0043] The intelligent monitoring method for farmland irrigation water includes multiple moisture sensors 100, water level sensors 102, a calibration mechanism, a solar power supply mechanism, a controller 101, and a data management mechanism; Multiple moisture sensors 100 are distributed and installed in different locations in the farmland to monitor the soil moisture content in real time. Water level sensors 102 are installed in the farmland through a calibration mechanism to monitor the soil water level. The calibration mechanism can calibrate the water level sensors 102 periodically or as needed to ensure the accuracy of the water level data. A solar power supply mechanism provides stable power support for the entire monitoring device to ensure the normal operation of each component. The controller 101 is connected to the moisture sensors 100, water level sensors 102, and the solar power supply mechanism, and is responsible for receiving the data collected by the sensors and performing preliminary processing and analysis. The controller 101 is connected to the data management mechanism through a wireless module to wirelessly transmit the processed data to the data management mechanism, realizing remote monitoring and management of the data. This allows managers to understand the moisture status of the farmland in a timely manner, formulate reasonable irrigation plans, achieve precision irrigation, improve irrigation efficiency, and save water resources.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
