Description

Technical Field

[0001] This invention belongs to the field of agricultural irrigation and intelligent control technology, specifically an agricultural automated irrigation management system based on smart water pumps. Background Technology

[0002] Agricultural irrigation, as a core component of agricultural production, directly impacts water resource utilization and crop yield efficiency through its level of automation and intelligence. With the development of the Internet of Things (IoT) and intelligent control technologies, smart water pumps are gradually replacing traditional pumps in agricultural irrigation. However, existing technologies still face numerous bottlenecks, making it difficult to meet the demands of large-scale, precision agricultural production.

[0003] Existing agricultural irrigation management systems have several shortcomings: First, traditional water pumps use fixed speeds and single-filtration designs, making it impossible to dynamically adjust flow and pressure according to irrigation needs. This results in water and energy waste, and the lack of anti-clogging and self-cleaning functions makes them prone to clogging and shutdowns due to impurities during field irrigation, leading to low levels of automation and intelligence in agricultural irrigation. Second, existing sprinkler systems cannot automatically adjust the spraying area according to irrigation needs, resulting in blind spots in irrigation coverage. Furthermore, when not in operation, these systems are vulnerable to damage from farm machinery, impacts, and harsh weather conditions, leading to frequent malfunctions and significantly shortened lifespans. Therefore, there is an urgent need to design an automated agricultural irrigation management system based on intelligent water pumps to address these issues. Summary of the Invention

Traditional water pumps use a fixed speed and a single filter design, which cannot dynamically adjust the flow and pressure according to irrigation needs.

[0032] The present invention provides the following embodiments.

[0033] Example 1

[0034] This invention provides an in-vehicle information monitoring system, such as... Figure 1 As shown, it includes a smart water pump unit, a multi-dimensional sensing unit, an intelligent control unit, an irrigation execution unit, and a cloud management unit. Each unit interacts with data and transmits instructions through a communication module to form a closed-loop management system. The irrigation execution unit is equipped with a buried telescopic sprinkler device.

[0035] The intelligent water pump unit adopts an electromechanical integrated structure, including an adjustable impeller water pump body, an adaptive speed adjustment mechanism, an anti-clogging self-cleaning device, and a status monitoring module;

[0036] The adaptive speed adjustment mechanism integrates a frequency converter and a torque sensor to dynamically adjust the motor speed, and the anti-clogging self-cleaning device is linked with the reverse flushing mechanism through a differential pressure sensor to achieve self-cleaning without stopping the machine.

[0037] Preferably, the multi-dimensional sensing unit includes a soil sensing component, an environmental sensing component, and a crop status sensing component. The soil sensing component is equipped with a soil moisture sensor, a conductivity sensor, and a temperature sensor. The crop status sensing component integrates an image acquisition module and a stem moisture sensor to construct a three-in-one sensing network of soil, environment, and crop.

[0038] Preferably, the intelligent control unit uses an ARM Cortex-M4 core microcontroller as the main controller, with a built-in crop growth cycle database and adaptive irrigation decision algorithm, and integrates a fault diagnosis module. The fault diagnosis module analyzes multi-dimensional data such as vibration, temperature, torque and filter pressure difference of the smart water pump based on an improved BP neural network algorithm, and can predict bearing wear, motor overload, filter blockage faults, and start a self-repair program.

[0039] Preferably, the cloud management unit includes a cloud server, a distributed data storage module, and a multi-terminal client application. The cloud server supports big data analysis to optimize irrigation decision-making algorithms, and users can remotely monitor, set parameters, and trace data through mobile apps and web pages to achieve centralized management of large-scale farmland.

[0040] The working principle and beneficial effects of the above technical solution are as follows:

[0041] The aforementioned agricultural automated irrigation management system based on smart water pumps is equipped with a smart water pump unit, a multi-dimensional sensing unit, an intelligent control unit, an irrigation execution unit, and a cloud management unit. Each unit interacts with data and transmits instructions through a communication module, forming a closed-loop management system covering the entire chain of "collection-decision-execution-feedback-optimization". Meanwhile, the smart water pump unit employs a collaborative design of an adjustable impeller mechanical structure and variable frequency electrical control to achieve precise dynamic regulation of flow rate and head. Simultaneously, the anti-clogging self-cleaning device, through the electromechanical linkage of differential pressure sensing and a reverse flushing mechanism, achieves non-stop self-cleaning, effectively solving the problem of impurity clogging in field irrigation, significantly reducing downtime due to malfunctions, and improving the efficiency of agricultural irrigation.

[0042] Secondly, the multi-dimensional sensing unit, combined with the intelligent control unit, distinguishes itself from existing single humidity sensing solutions by constructing a three-dimensional sensing network integrating soil, environment, and crops. For the first time, it integrates crop stem humidity and machine vision growth cycle recognition into irrigation decision-making. Based on neural network algorithms, it optimizes decision-making logic to achieve dynamic matching of irrigation parameters with crop needs and environmental conditions, improving irrigation accuracy by more than 30% and water resource utilization by 25%-35% compared to existing technologies. At the same time, the fault prediction algorithm based on multi-parameter fusion enables early warning and self-repair of faults such as bearing wear and motor overload, improving fault handling efficiency by 90% and extending equipment life by 1.5 times compared to existing technologies.

[0043] The aforementioned irrigation management system deploys smart water pump units at the water source based on farmland size and crop type to ensure stable water levels at the inlet. Multi-dimensional sensor units are buried at preset intervals in the tillage layer and at the highest points in the field, with soil sensors buried at a depth of 20-30cm to avoid interference from tillage. Irrigation execution units are then deployed according to crop planting row spacing, with sprinkler and drip irrigation components configured in separate zones. The intelligent control unit is installed in a field control box, ensuring ventilation and dryness, while the cloud management unit completes server deployment and client debugging.

[0044] The specific operation process of this system is as follows: First, the user sets the crop type, growth stage, and irrigation preference parameters through the client. The cloud management unit synchronizes this information to the intelligent control unit, and the main controller loads the corresponding crop's irrigation decision model. Next, the multi-dimensional sensing unit collects soil, environmental, and crop status data in real time and transmits it to the intelligent control unit through the communication module. The edge computing module preprocesses and filters the data for anomalies. Then, based on the preprocessed data and the irrigation decision model, the main controller generates an irrigation plan, drives the smart water pump unit to adjust its speed and flow rate, and controls the irrigation execution unit to switch irrigation modes and adjust the spray angle. At the same time, the operating status data of the smart water pump unit and the irrigation execution unit are transmitted back in real time. The fault diagnosis module continuously analyzes the equipment status, automatically starts the self-repair program when a fault is detected, and uploads the data to the cloud. The cloud management unit optimizes the decision model through big data analysis and regularly pushes irrigation reports and equipment maintenance suggestions to the client.

[0045] Example 2

[0046] Based on Example 1, such as Figures 2-4 As shown, the buried telescopic sprinkler device includes a mounting base 1, an outer cylinder 2 fixedly mounted on the top of the mounting base 1, a drive mechanism 3 disposed inside the outer cylinder 2, a mounting cylinder 4 slidably connected inside the outer cylinder 2, a first mounting plate 5 fixedly mounted on the top of the drive mechanism 3, a rotation adjustment mechanism 6 disposed on the top of the first mounting plate 5, a multi-directional adjustment mechanism 7 mounted on the top of the adjustment mechanism, a sprinkler adjustment mechanism 8 mounted on the multi-directional adjustment mechanism 7, and two cylinder covers 9 symmetrically hinged to the top of the mounting cylinder 4.

[0047] Preferably, the drive mechanism 3 includes a forward and reverse drive motor 31, which is fixedly mounted on the top of the mounting base 1. The lower end of the threaded rod 32 is fixedly connected to the output shaft of the forward and reverse drive motor 31, and the middle section of the threaded rod 32 has a smooth cylindrical surface. An adjusting plate 33 is fixedly mounted on the bottom of the mounting cylinder 4, and the adjusting plate 33 is threadedly connected to the threaded rod 32. The side wall of the adjusting plate 33 is slidably connected to the inner wall of the outer cylinder 2. The drive base 34 is threadedly connected to the threaded rod 32. The slide 35 is fixedly connected to the inner wall of the mounting cylinder 4, and the top of the threaded rod 32 is rotatably connected to the top of the slide 35. The side wall of the drive base 34 is slidably connected to the slide 35. A plurality of guide sleeves 36 are fixedly installed on the top of the drive base 34 at circumferential intervals. The first mounting plate 5 is sleeved on the top of the slide 35. A plurality of top rods 37 are fixedly installed on the bottom of the first mounting plate 5 at circumferential intervals, and the installation positions of the plurality of top rods 37 correspond one-to-one with the plurality of guide sleeves 36.

[0048] Preferably, the rotation adjustment mechanism 6 includes a support shaft 61, which is rotatably mounted on the top of the first mounting plate 5. A driven gear 62 is fixedly mounted on the support shaft 61. A servo motor 63 is fixedly mounted on the top of the first mounting plate 5. A drive gear 64 is fixedly connected to the output shaft of the servo motor 63, and the drive gear 64 meshes with the driven gear 62.

[0049] The working principle and beneficial effects of the above technical solution are as follows:

[0050] The aforementioned underground telescopic sprinkler system can be completely hidden below the ground surface when not in operation, avoiding damage from tillage machinery and erosion from severe weather. During operation, it achieves smooth raising and lowering via mechanical transmission, thus completing full-range spraying. When the underground telescopic sprinkler system is in operation, the forward and reverse drive motor 31, fixedly mounted on the top of the mounting base 1, is first activated. This causes the threaded rod 32, fixedly connected to the output shaft of the motor 31, to rotate. Then, the adjusting plate 33, threaded onto the threaded rod 32, moves upward along the inner wall of the outer cylinder 2, simultaneously driving the mounting cylinder 4 upward until the adjusting plate 33 reaches its limit position at the top of the outer cylinder 2. At this point, the adjusting plate 33 is positioned at the smooth cylindrical part in the middle of the threaded rod 32, thus resting there after the threaded rod 32 is deactivated. This completes the smooth raising of the entire mounting cylinder 4 from below the ground surface to above, completing the subsequent spraying operation. Simultaneously, the drive base 34, under the action of the slide 35, continuously moves upward along the mounting cylinder 4, as the adjusting plate 33 drives the mounting cylinder 4 to the working position... After positioning, the first mounting plate 5 is sleeved on the top of the slide 35, and several top rods 37 are fixedly installed at circumferential intervals on the bottom of the first mounting plate 5. At this time, several guide sleeves 36 fixedly installed on the drive base 34 will cooperate with several top rods 37 one by one. Then, as the drive base 34 moves upward, it drives the rotation adjustment mechanism 6, multi-directional adjustment mechanism 7 and spray adjustment mechanism 8 set on the top of the first mounting plate 5 to rise to the required working position of the spraying device, and then completes the automated irrigation of agriculture. Secondly, after the device completes the spraying operation, the forward and reverse drive motors 31 rotate in the opposite direction, so that the drive base 34 and the adjustment plate 33 move downward along the mounting cylinder 4 and the outer cylinder 2 respectively, so that the various mechanisms in the spraying device return to the initial position in the mounting cylinder 4, and the mounting cylinder 4 also retracts back below the ground surface to complete the concealment.

[0051] Secondly, the rotary adjustment mechanism 6, located on the first mounting plate 5, allows for the horizontal rotation adjustment of the sprinkler adjustment mechanism 8, thereby better meeting the irrigation requirements of the sprinkler system. When rotation adjustment is needed, the servo motor 63 is activated, driving the drive gear 64 to rotate. The drive gear 64 meshes with the driven gear 62, which in turn drives the support shaft 61, which is fixedly connected to the driven gear 62, to rotate horizontally along the top of the first mounting plate 5. This smoothly completes the horizontal angle adjustment of the sprinkler adjustment mechanism 8, better adapting to agricultural irrigation needs.

[0052] Example 3

[0053] Based on Example 1 or 2, such as Figures 4-6 As shown, the multi-directional adjustment mechanism 7 includes a fixed frame 71, which is fixedly installed on the top of the support shaft 61. Two drive motors 72 are symmetrically fixedly installed on the side wall of the fixed frame 71 at a distance from each other. The output shafts of the two drive motors 72 are respectively rotatably connected to drive bevel gears 73 after passing through the side wall of the fixed frame 71. A mounting shaft 74 is fixedly connected to one side of the fixed frame 71, and transmission gear sets 75 are rotatably installed at both ends of the mounting shaft 74. The transmission gear sets 75 are composed of two symmetrically connected transmission bevel gears. One end of the mounting rod 76 is fixedly connected to one side of the transmission gear set 75. One end of the fixed shaft 77 is rotatably connected to one end of the mounting rod 76 and is fixedly installed with a driven bevel gear 78. The driven bevel gear 78 meshes with the two transmission gear sets 75. A mounting bracket 79 is fixedly installed on the other end of the mounting rod 76, and a second mounting plate 710 is fixedly installed on the top of the mounting bracket 79.

[0054] Preferably, the spray adjustment mechanism 8 includes a mounting frame 81, which is fixedly mounted on the top of the second mounting plate 710. A low-speed motor 82 is fixedly mounted on the bottom of the second mounting plate 710. The lower end of the drive shaft 83 rotates through the side walls of the mounting frame 81 and the second mounting plate 710 in sequence and is fixedly connected to the output shaft of the low-speed motor 82. A sliding sleeve 84 is slidably connected to the drive shaft 83. The fixed end of the electric telescopic rod 85 is embedded in the second mounting plate 710, and a drive disk 86 is fixedly mounted on the telescopic end of the electric telescopic rod 85. The drive disk 86 makes rolling contact with the side wall of one end of the sliding sleeve 84.

[0055] Preferably, the system further includes a fixing rod 87, the lower end of which is rotatably connected to the top of the mounting bracket 81. A connecting rod 88 is hinged to the side wall of the lower end of the fixing rod 87. A slider 89 is fixedly connected to the lower end of the connecting rod 88. The slider 89 is slidably connected in the slide groove 810. Two L-shaped brackets 811 are symmetrically hinged to the side wall of the slide groove 810. The side wall of the slider 89 is slidably connected to the groove 812 embedded at one end of each of the two L-shaped brackets 811. The other end of the L-shaped bracket 811 is hinged to the side wall of the sliding sleeve 84. A spray head 813 is fixedly installed on the top of the connecting rod 88. A connecting pipe 814 is fixedly connected to the side wall of the mounting bracket 81 through two fixing plates 815. The outlet of the connecting pipe 814 is connected to the spray head 813 through a telescopic hose 816.

[0056] The beneficial effects of the above technical solution are as follows:

[0057] The aforementioned multi-directional adjustment mechanism 7 enables the sprinkler adjustment mechanism 8 to perform vertical adjustments in multiple directions, better cooperating with the sprinkler adjustment components to meet irrigation needs. When the multi-directional adjustment mechanism 7 is adjusted, two drive motors 72 are symmetrically fixedly mounted on the side wall of the fixed frame 71 at a distance from each other. When the two drive motors 72 rotate in the same direction (forward or reverse), the two drive bevel gears 73 rotate synchronously. Then, the two drive bevel gears 73 mesh with two transmission gear sets 75, which consist of two symmetrically connected transmission bevel gears. The two transmission gear sets 75 then rotate in opposite directions along the mounting shaft 74. One end of the mounting rod 76 is fixedly connected to one side of the transmission gear set 75. One end of the fixed shaft 77 rotates through one end of the mounting rod 76 and is fixedly mounted with a driven bevel gear 78. At this time, the driven bevel gear 78 meshes with the two transmission gear sets 75, causing the driven bevel gear 78 to drive the fixed shaft 77. Rotating along one end of the mounting rod 76 causes the second mounting plate 710, which is fixedly connected to the fixed shaft 77 via the mounting bracket 79, to rotate around the fixed shaft 77, thereby adjusting the spray posture of the spray adjustment mechanism 8 on the second mounting plate 710. At the same time, when the two drive motors 72 rotate in opposite directions, the two drive bevel gears 73 rotate synchronously, and then the two transmission gear sets 75 rotate in the same direction along the mounting shaft 74, so that the driven bevel gear 78 meshing with the two transmission gear sets 75 does not rotate. Then, the second mounting plate 710, which is fixedly connected to the fixed shaft 77 via the mounting bracket 79, rotates around the mounting shaft 74, thereby adjusting the spray posture of the spray adjustment mechanism 8 on the second mounting plate 710.

[0058] The aforementioned spray adjustment mechanism 8 can adjust the spray swing angle and swing speed of the spray head 813 in real time according to agricultural irrigation needs, so as to better adapt to the automatic adjustment of the spray head 813 under different conditions. At the same time, in conjunction with the rotary adjustment mechanism 6 and the multi-directional adjustment mechanism 7, the spray angle can be freely adjusted, which greatly avoids blind spots in irrigation coverage, thereby effectively improving the working efficiency and reliability of the spray device during agricultural irrigation. When the sprinkler adjustment mechanism 8 needs to be adjusted according to irrigation requirements, the low-speed motor 82 is first started, which drives the drive shaft 83 to rotate. Then, the sliding sleeve 84, which is slidably connected to the drive shaft 83, rotates synchronously. The slider 89 is slidably connected in the groove 810. The side wall of the slider 89 is slidably connected to the groove 812 embedded at one end of the two L-shaped brackets 811. At this time, the connecting rod 88 connected to the groove 810 through the slider 89 will not swing, and the sprinkler head 813, which is rotatably connected to the top of the mounting frame 81 through the fixed rod 87, will also not swing. At this time, the sprinkler head 813 is in the initial position. As the electric telescopic rod 85 is extended and retracted, the drive disc 86, which is fixedly connected to the extension end of the electric telescopic rod 85, moves up and down. The drive disc 86 rolls against the side wall of one end of the sliding sleeve 84, making the... The sliding sleeve 84 can slide up and down along the drive rod. Then, the sliding sleeve 84 drives the slider 89 to slide along the slide groove 810 via two L-shaped brackets 811, thereby changing the position of the slider 89 in the slide groove 810. Next, the connecting rod 88, fixedly connected to the slider 89, swings continuously as the slide groove 810 rotates, causing the connecting rod 88 to adjust the spray angle of the sprinkler head 813 mounted on the fixed rod 87, thus achieving spraying in different farmland irrigation areas. Simultaneously, the swing amplitude of the connecting rod 88 can be changed by extending or retracting the electric telescopic rod 85, thereby changing the spray range of the sprinkler head 813, effectively increasing the spray range of the sprinkler device and avoiding irrigation blind spots. Furthermore, the swing frequency of the connecting rod 88 can be changed by adjusting the extension and retraction speed of the electric telescopic rod 85, thus achieving a better spraying effect of the sprinkler head 813 on the irrigation area. The above invention can better cooperate with the agricultural automated irrigation management system based on intelligent water pumps to complete farmland irrigation, and also greatly improves the automation and intelligence level of agricultural irrigation.
