Description

Technical Field

[0001] This invention belongs to the field of agricultural intelligent device technology, specifically relating to an irrigation and drainage method for an intelligent integrated irrigation and drainage pipeline system. Background Technology

[0002] The "National High-Standard Farmland Construction Plan (2021-2030)" emphasizes achieving drought and flood resistance, high and stable yields in high-standard farmland. Current farmland irrigation and drainage mainly rely on open channels, culverts, shafts, and pipe networks. Open channels have high evaporation rates, while culverts and shafts are prone to collapse and blockage. Pipe networks, with their energy-saving, convenient construction, low cost, and safety advantages, are gradually becoming the preferred choice.

[0003] In recent years, farmland irrigation networks have covered most parts of the country. However, in the process of improving farmland networks, irrigation is often emphasized, but drainage is neglected. Farmland is uneven and has low disaster resistance. Without a sound irrigation and drainage system, a lot of manpower and resources will be wasted on irrigation and drainage. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an irrigation and drainage method for an integrated intelligent irrigation and drainage network system, so as to improve the irrigation and drainage system of farmland and enhance the disaster prevention capabilities of farmland crops.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses an intelligent integrated irrigation and drainage pipeline system and its irrigation and drainage method. The intelligent integrated irrigation and drainage pipeline system includes a control system, a plurality of irrigation and drainage piles, an underground pipeline network, a power pump, and a well. The underground pipeline network is buried below the cultivated layer of farmland. The plurality of irrigation and drainage piles are installed on the underground pipeline network. One end of each irrigation and drainage pile is connected to the underground pipeline network, and the other end of each irrigation and drainage pile extends above the cultivated layer of farmland. One end of the power pump is located in the well, and the other end of the power pump is connected to one end of the underground pipeline network. Each irrigation and drainage pile includes a pile body, and the pile body is provided with an irrigation pipe, a drainage pipe, a water level monitoring device, a moisture content monitoring device, and a wireless signal transmission device. The irrigation pipe and the drainage pipe are respectively provided with an irrigation device and a drainage device. The water level monitoring device, the irrigation pipe, the drainage pipe, and the wireless signal transmission device are located above the cultivated layer of farmland, and the moisture content monitoring device is located within the cultivated layer of farmland. The power pump, the water level monitoring device, the moisture content monitoring device, and the wireless signal transmission device are electrically connected to the control system.

[0007] The irrigation method of the intelligent integrated irrigation and drainage network system includes the following steps:

[0008] Set appropriate thresholds for moisture content monitoring devices according to different crops;

[0009] When the moisture content monitoring device detects that the soil moisture content is lower than the monitoring threshold, the wireless signal transmission device will feed the monitoring data back to the control system.

[0010] The control system controls the start of the power pump, which transports the water in the well to the irrigation and drainage piles through the underground pipe network, and then discharges it through the irrigation pipes of the irrigation and drainage piles to irrigate the crops.

[0011] When the moisture content monitoring device detects that the soil moisture content is higher than the monitoring threshold, the wireless signal transmission device will feed the monitoring data back to the control system, and the control system will shut down the power pump.

[0012] The drainage method of the intelligent integrated irrigation and drainage network system includes the following steps:

[0013] Set appropriate thresholds for water level monitoring devices according to different crops;

[0014] When the water level monitoring device detects that the farmland water level is higher than the monitoring threshold, the wireless signal transmission device will feed the monitoring data back to the control system.

[0015] The control system controls the start of the power pump, which draws water from the farmland into the underground pipe network through the drainage pipe, and then discharges it into the well.

[0016] When the water level monitoring device detects that the farmland water level is below the monitoring threshold, the wireless signal transmission device will feed the monitoring data back to the control system, and the control system will shut down the power pump.

[0017] Furthermore, an auxiliary drainage pipe is provided at the end of the underground pipe network. One end of the auxiliary drainage pipe is connected to the underground pipe network, and the other end of the auxiliary drainage pipe is equipped with an auxiliary power pump. The outlet of the auxiliary power pump is connected to the well. The auxiliary power pump is electrically connected to the control system. Its advantage is that, in this system, the power pump is a bidirectional power pump. When draining, the pump's suction force may be insufficient due to the blade orientation. Therefore, adding an auxiliary power pump increases the suction force and improves the drainage effect of farmland. Of course, it is easy to understand that two separate power pumps can be used for drainage and irrigation.

[0018] Furthermore, the pile body of the irrigation and drainage pile is hollow, and a connecting pipe is provided at one end of the pile body that connects to the underground pipe network. One end of the connecting pipe is connected to the pile body, and the other end is connected to the underground pipe network. The irrigation device includes a sprinkler head, and the sprinkler head is connected to the end of the irrigation pipe. The drainage device includes a collection well and a suction pipe. One end of the suction pipe is connected to the end of the drainage pipe, and the other end of the suction pipe is located in the collection well, which is set within the soil layer. The suction pipe and the irrigation pipe are respectively provided with a first one-way mechanism and a second one-way mechanism for controlling the direction of water flow. The advantage of this arrangement is that it allows the tank to... Irrigation and drainage of the pile system operate independently without interference. A single pile can achieve both irrigation and drainage through an underground pipe network, eliminating the need for separate pipe networks beneath the soil. It should be noted that water collection wells can be installed at intervals, not at every single pile. These wells should be located in lower-lying areas of the farmland, depending on the specific conditions. Sensors, such as level sensors, can be installed within the water collection wells to assist drainage systems, and protrusions can be added to the top of the wells to accommodate varying water levels in the farmland. This is existing technology and will not be elaborated upon further.

[0019] Furthermore, the pile body is provided with a first spring, a piston, a connecting rod, a piston ring, and a connecting pipe from top to bottom. One end of the first spring is fixed to the inner wall of the upper end of the pile body, and the other end is fixed to the middle of the piston. The two ends of the connecting rod are respectively fixed to the middle of the piston and the middle of the piston ring. An auxiliary irrigation pipe is also provided on the drainage pipe. One end of the auxiliary irrigation pipe is connected to the drainage pipe. A third one-way mechanism for controlling the direction of water flow is provided in the auxiliary irrigation pipe. The first one-way mechanism and the third one-way mechanism are used to control the water flow in the underground pipe network to the farmland, and the second one-way mechanism is used to control the water flow in the collection well to the underground pipe network.

[0020] By controlling the output power of the power pump, the pressure of the delivered water can be controlled. When the water pressure is high, it overcomes the resistance of the first spring and pushes the piston upward. As the piston moves upward, it also drives the piston rings upward. At this time, the piston rings seal the end of the drain pipe (the side walls of the piston rings block the drain pipe opening), while the upper piston protrudes from the end of the irrigation pipe. Therefore, water will flow out from the irrigation pipe and then through the sprinkler head to achieve the irrigation effect. When the water pressure is lost, the piston and piston rings (the piston rings refer to the piston with the hole in the middle) are pushed back to their original positions by the action of the first spring. When the water pressure is low, it is not enough to overcome the resistance of the first spring, so the water can only be discharged from the auxiliary irrigation pipe, thus achieving flood irrigation of the farmland.

[0021] Furthermore, a water collection tank, an end cap, a second spring, and a stop are sequentially arranged below the auxiliary irrigation pipe. The stop is fixed to the suction pipe. The second spring, the end cap, and the water collection tank are all slidably sleeved on the suction pipe. Several permeation holes are provided on the side of the water collection tank. The end cap matches the wellhead of the irrigation well. The advantage of this design is that the water collection well facilitates the collection of water during farmland flooding, allowing it to be discharged into the well via the suction pipe. However, this also presents the problem that when the device performs flood irrigation, water flowing through the farmland can also flow into the water collection well. Therefore, the above-described mechanism can be used to address this issue. To avoid this problem, the principle is as follows: when the auxiliary irrigation pipe drains water, the water flows into the collection tank. Under the action of gravity, the water overcomes the resistance of the second spring and moves downward, thus lowering the end cap and sealing the well opening of the collection well. This prevents water from flowing into the collection well during flood irrigation. After flood irrigation ends, the water in the collection tank will continuously drain out through the seepage holes (during flood irrigation, the inflow is greater than the outflow, so it will always be full and overflowing; while on rainy days, the inflow of rainwater is less than the outflow from the seepage holes), thus reducing the weight. Under the action of the second spring, the end cap will detach from the inlet of the collection well, preparing for flood prevention and water intake.

[0022] Furthermore, the first, second, and third one-way mechanisms all include symmetrically arranged baffles in a "figure-eight" shape. A rolling sealing ball is positioned between the baffles. The advantage of this is that the sealing ball moves under water pressure. When it contacts the narrow end of the baffle, it is in a closed state; when it moves away from the narrow end, it is in a connected state. It is easy to understand that the baffle should be an arc-shaped plate to better fit the surface of the sealing ball. Additionally, a limiting ring should ideally be provided at the wide end of the baffle to prevent the sealing ball from rolling out of the pipe.

[0023] Furthermore, the wellhead of the water collection well is provided with a concrete slope. The advantage of this slope is that it prevents the soil at the end from becoming loose and entering the water collection well, while also ensuring the sealing effect of the end cap on the water collection well.

[0024] Furthermore, the auxiliary irrigation pipe is provided with a branch pipe, one end of which is connected to the auxiliary irrigation pipe and the other end is located in the water collection tank. Its advantage is that the branch pipe can ensure the effect and amount of water discharged into the water collection tank and adapt to different settings of the auxiliary irrigation pipe.

[0025] Furthermore, the irrigation method of the intelligent integrated irrigation and drainage network system also includes the control system using weather forecasts to determine whether to carry out irrigation operations on the same day. The advantage of this is that it avoids repeated irrigation and waste of water resources.

[0026] Furthermore, it also includes an APP that works in conjunction with this intelligent irrigation and drainage integrated pipeline network system. Its advantage is that it makes it easier for farm personnel to understand the drought and flood conditions of the farmland, and they can manually control the system based on their experience in dealing with drought and flood conditions, thus realizing manual irrigation and drainage operations, making it more convenient to use.

[0027] The beneficial effects of this invention are as follows:

[0028] (1) This technical solution proposes an intelligent irrigation and drainage integrated pipeline network system for farmland, which is simple to operate and highly economical;

[0029] (2) This technical solution proposes a “monitoring-early warning-irrigation” method based on farmland soil moisture content, which provides real-time feedback through monitoring data and timely irrigation.

[0030] (3) This technical solution proposes a “monitoring-early warning-drainage” method based on farmland surface water level, which provides real-time feedback through monitoring data and timely drainage;

[0031] (4) The specific structure of this system and the irrigation and drainage piles in the system enables the system to use the same set of underground pipe network to select the sprinkler or flood irrigation operation for crops according to different crops and the degree of high temperature, and also to realize the drainage operation for flood prevention. That is, the structure of this system is scientific and simple, and can better realize the intelligent irrigation and drainage of farmland.

[0032] (5) The integrated irrigation and drainage network of this technical solution is a single network for both irrigation and drainage, which saves agricultural land and construction costs, improves land use efficiency, and at the same time, uses underground pipes instead of open ditches and canals to reduce the division of farmland and facilitate the operation of large agricultural machinery.

[0033] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention.

[0043] like Figures 1-6 As shown, this invention discloses an irrigation and drainage method for an integrated intelligent irrigation and drainage network system. The integrated intelligent irrigation and drainage network system includes a control system, several irrigation and drainage piles 1, an underground pipeline network 2, a power pump 3, and a well 4. The underground pipeline network 2 is buried below the cultivated layer of farmland 7. Several irrigation and drainage piles 1 are installed on the underground pipeline network 2, with one end of each pile connected to the underground pipeline network 2 and the other end extending above the cultivated layer of farmland 7. One end of the power pump 3 is connected to the well 4 via a pipe, and the other end of the power pump 3 is connected to one end of the underground pipeline network 2. Each irrigation and drainage pile 1 includes a pile body. 8. The pile body 8 is equipped with an irrigation pipe 20, a drainage pipe 22, a water level monitoring device 10, a moisture content monitoring device 11, and a wireless signal transmission device 9. The irrigation pipe 20 and the drainage pipe 22 are respectively equipped with an irrigation device 12 and a drainage device 13. The water level monitoring device 10, the irrigation pipe 20, the drainage pipe 22, and the wireless signal transmission device 9 are located above the cultivated layer of the farmland 7, and the moisture content monitoring device 11 is located inside the cultivated layer of the farmland 7. The power pump 3, the water level monitoring device 10, the moisture content monitoring device 11, and the wireless signal transmission device 9 are electrically connected to the control system.

[0044] The irrigation method of the intelligent integrated irrigation and drainage network system includes the following steps:

[0045] The corresponding threshold values ​​for the moisture content monitoring device 11 are set according to different crops;

[0046] When the moisture content monitoring device 11 detects that the soil moisture content is lower than the monitoring threshold, the wireless signal transmission device 9 feeds back the monitoring data to the control system.

[0047] The control system controls the start of the power pump 3, which transports the water in the well 4 to the irrigation and drainage pile 1 through the underground pipe network 2, and discharges it through the irrigation pipe 20 of the irrigation and drainage pile 1 to irrigate the crops.

[0048] When the moisture content monitoring device 11 detects that the soil moisture content is higher than the monitoring threshold, the wireless signal transmission device 9 feeds back the monitoring data to the control system, and the control system controls the power pump 3 to shut down.

[0049] The drainage method of the intelligent integrated irrigation and drainage network system includes the following steps:

[0050] The water level monitoring device 10 is set with corresponding thresholds according to different crops;

[0051] When the water level monitoring device 10 detects that the water level in farmland 7 is higher than the monitoring threshold, the wireless signal transmission device 9 will feed back the monitoring data to the control system.

[0052] The control system controls the start of the power pump 3, which draws water from the farmland 7 into the underground pipe network 2 through the drainage pipe 22, and then discharges it into the well 4.

[0053] When the water level monitoring device 10 detects that the water level in farmland 7 is lower than the monitoring threshold, the wireless signal transmission device 9 feeds back the monitoring data to the control system, and the control system controls the power pump 3 to shut down.

[0054] This technical solution designed and implemented an integrated intelligent irrigation and drainage pipeline system for farmland. The system consists of six parts: irrigation and drainage piles (1), underground pipeline network (2), power pumps (3), wells (4), and software (APP). See [link / details]. Figure 1 The irrigation and drainage pile 1 consists of the pile body 8, irrigation device 12, water level monitoring device 10, drainage device 13, moisture content monitoring device 11, and wireless signal transmission device 9, as shown in the figure. Figure 2Irrigation and drainage piles 1 are installed in farmland 7, and a pipeline network is laid below the cultivated layer of farmland 7. The irrigation and drainage piles 1 are connected to the river and well 4 through the underground pipeline network 2. Power supply and power pump 3 are configured. The water level and soil moisture content of farmland 7 are monitored by water level monitoring device 10 and moisture content monitoring device 11. Different thresholds are set according to different crops. When the water level of farmland 7 is higher than the surface water level threshold, data is fed back to the system via wireless signal to activate the automatic drainage function. The drainage device 13 introduces the accumulated water of farmland 7 into the pipeline network and discharges it into the river and well 4. When the soil moisture content is lower than the soil moisture content threshold, data is fed back to the system via wireless signal. The system determines whether to activate the automatic irrigation function. Water is drawn into the underground pipeline network 2 by the power pump 3 and irrigated by the irrigation device 12.

[0055] The underground pipe network 2 connects the water source 6 to the irrigation piles, and its main function is to transport water. The pipe materials used include, but are not limited to, polyethylene, polyvinyl chloride, polypropylene, steel, and concrete. The main function of the power pump 3 is to provide power for water intake and drainage; a bidirectional pump is preferred. The well 4 is a well that uses the power pump 3 to draw water. The main function of the irrigation device 12 is to irrigate the farmland 7 when the automated irrigation function is activated, including, but not limited to, flood irrigation pipe devices and sprinkler head 21 devices. The main function of the drainage device 13 is to divert excess water from the farmland 7 into the underground pipe network 2 for drainage when the automated drainage function is activated, including, but not limited to, [other types of drainage devices]. Limited to seepage drainage devices and downwell drainage devices; the main function of the water level monitoring device 10 is to monitor surface water level data through water level measuring elements, and to feed back water level data and receive instructions through the wireless signal transmission device 9, including but not limited to the use of electronic water level gauges and mechanical water level gauges; the main function of the moisture content monitoring device 11 is to monitor soil moisture content data through soil moisture content measuring elements, and to feed back soil moisture content data and receive instructions through the wireless signal transmission device 9, including but not limited to the use of moisture meters and soil hygrometers; water level monitoring technology measures the pressure applied by the water column through a liquid pressure sensor and converts it into water depth data. Moisture content monitoring technology uses block resistors to convert resistance data into moisture content by utilizing the relationship between soil resistance and moisture content. Wireless sensor network technology collects water depth data and moisture content data, and realizes real-time transmission and tracking of field data. Internet of Things (IoT) technology can connect different types of devices to a network to realize remote monitoring and control via mobile devices.

[0056] An auxiliary drainage pipe 5 is provided at the end of the underground pipe network 2. One end of the auxiliary drainage pipe 5 is connected to the underground pipe network 2, and the other end of the auxiliary drainage pipe 5 is equipped with an auxiliary power pump. The outlet of the auxiliary power pump is connected to the well 4. The auxiliary power pump is electrically connected to the control system. In this system, the power pump 3 is a bidirectional power pump 3. When draining, the suction force of the power pump 3 may be insufficient due to the direction of the blade setting. Therefore, an auxiliary power pump is added to increase the suction force and improve the drainage effect of the farmland 7. Of course, it is easy to understand that two separate power pumps 3 can be used for drainage and irrigation.

[0057] Specifically, the specific structure of the irrigation and drainage pile 1 is as follows: the pile body 8 of the irrigation and drainage pile 1 is hollow inside, and a connecting pipe 19 is provided on one end of the pile body 8 that connects to the underground pipe network 2. One end of the connecting pipe 19 is connected to the pile body 8, and the other end is connected to the underground pipe network 2. The irrigation device 12 includes a sprinkler head 21, and the ends of the sprinkler head 21 and the irrigation pipe 20 are connected. In this specific embodiment, it is preferable to use a water collection well 24 for drainage. Specifically, the drainage device 13 includes a water collection well 24 and a suction pipe 23. One end of the suction pipe 23 is connected to the end of the drainage pipe 22, and the other end of the suction pipe 23 is located inside the water collection well 24. The well 24 is set within the soil layer. The suction pipe 23 and the irrigation pipe 20 are respectively equipped with a first one-way mechanism and a second one-way mechanism to control the direction of water flow. With this arrangement, the irrigation and drainage of the pump pile can work independently without interfering with each other. One pump pile 1 can realize irrigation and drainage through the underground pipe network 2 without the need to lay corresponding pipe networks under the soil layer. Of course, it should be noted that the collection wells 24 can be set at a certain distance, and it is not necessary to set one for each pump pile 1. At the same time, the collection wells 24 should be set in a lower position in the farmland 7, which can be selected according to the actual situation.

[0058] In one embodiment, the pile body 8 is provided with a first spring 14, a piston 15, a connecting rod 18, a piston ring 17, and a connecting pipe 19 from top to bottom. One end of the first spring 14 is fixed to the upper inner wall of the pile body 8, and the other end is fixed to the middle of the piston 15. The two ends of the connecting rod 18 are respectively fixed to the middle of the piston 15 and the middle of the piston ring 17. A crossbar 16 is provided in the middle of the piston ring, and the end of the connecting rod 18 is fixed to the crossbar 16. An auxiliary irrigation pipe 33 is also provided on the drainage pipe 22. One end of the auxiliary irrigation pipe 33 is connected to the drainage pipe 22. A third one-way mechanism is provided in the auxiliary irrigation pipe 33 to control the direction of water flow. The first one-way mechanism and the third one-way mechanism are used to control the water flow in the underground pipe network 2 to the farmland 7, and the second one-way mechanism is used to control the water flow in the collection well 24 to the underground pipe network 2.

[0059] By controlling the output power of the power pump 3, the pressure of the delivered water can be controlled. When the water pressure is high, the water pressure overcomes the resistance of the first spring 14 and pushes the piston 15 upward. As the piston 15 moves upward, it also drives the piston ring 17 upward. At this time, the piston ring 17 seals the end of the drain pipe 22 (the side wall of the piston ring 17 blocks the connection of the drain pipe 22), while the upper piston 15 protrudes from the end of the irrigation pipe 20. Therefore, the water will be discharged from the irrigation pipe 20 and then pass through the nozzle 21 to achieve the irrigation effect. When the water pressure is lost, the piston 15 and piston ring 17 (the piston ring 17 refers to the piston 15 with the hole in the middle) are pushed back to their original positions under the action of the first spring 14. When the water pressure is low, the water pressure is not enough to overcome the resistance of the first spring 14, so the water can only be discharged from the auxiliary irrigation pipe 33, which achieves flood irrigation of the farmland 7.

[0060] Below the auxiliary irrigation pipe 33, a water collection tank 28, an end cap 27, a second spring 26, and a stop block 25 are sequentially arranged. The stop block 25 is fixed to the suction pipe 23. The second spring 26, the end cap 27, and the water collection tank 28 are all slidably sleeved on the suction pipe. The side of the water collection tank 28 is provided with several seepage holes. The end cap 27 matches the wellhead of the water well. The water collection well 24 is designed to facilitate the collection of water into the water collection well 24 during flooding of farmland 7, and then discharge it into the machine well 4 through the suction pipe 23. However, when the device is used for flood irrigation, the water flowing in the farmland 7 will also flow into the water collection well 24. Therefore, the above-described mechanism can avoid this problem. The principle is as follows: when the auxiliary irrigation pipe 33 drains water, the water will flow into the water collection tank 28. Under the action of gravity, the water will overcome the resistance of the second spring 26 and move downward, which will move the end cover 27 downward, so that the end cover 27 seals the well opening of the water collection well 24, preventing the water from flowing into the water collection well 24 during flood irrigation. After the flood irrigation is over, the water in the water collection tank 28 will be continuously discharged through the seepage hole 29 (during flood irrigation, the inflow is greater than the outflow, and it will always be full and overflowing, while on rainy days, the inflow of rainwater is less than the outflow from the seepage hole 29), thus making the weight lighter. Under the action of the second spring 26, the end cover 27 will be removed from the inlet of the water collection well 24, preparing for flood prevention and water intake.

[0061] The first, second, and third one-way mechanisms all include symmetrically arranged baffles in a "V" shape. A rolling sealing ball is positioned between the baffles. Under water pressure, the sealing ball moves, forming a closed state when in contact with the narrow end of the baffle and a connected state when away from the narrow end. It's easy to understand that the baffle should be curved to better fit the surface of the sealing ball. A limiting ring should ideally be provided at the wide end of the baffle to prevent the sealing ball from rolling out of the pipe. Specifically, the first one-way mechanism includes a first baffle 31, a first sealing ball 32, and a first limiting ring 30; the second one-way mechanism includes a second baffle 35, a second sealing ball 36, and a second limiting ring 34.

[0062] The wellhead of the water collection well 24 is provided with a concrete ramp. The ramp is designed to prevent the soil at the end from loosening and entering the water collection well 24. It also ensures the sealing effect of the end cover 27 on the water collection well 24. In addition, the ramp also serves to guide the water flow.

[0063] Preferably, the auxiliary irrigation pipe 33 is provided with a branch pipe, one end of which is connected to the auxiliary irrigation pipe 33 and the other end is located in the water collection tank 28. The branch pipe can ensure the effect and amount of water discharged into the water collection tank 28 and adapt to different settings of the auxiliary irrigation pipe 33.

[0064] The irrigation method of the intelligent integrated irrigation and drainage network system also includes a control system that combines the weather forecast for the next three days to determine whether to carry out irrigation operations on the current day, avoiding repeated irrigation and waste of water source 6. It also includes an app that works in conjunction with this intelligent integrated irrigation and drainage network system, allowing farm personnel to understand the drought and flood conditions of farmland 7 and manually control the system based on their experience in handling drought and flood conditions, enabling manual irrigation and drainage operations, making it more convenient to use.

[0065] The water level and soil moisture content of farmland 7 are monitored by water level monitoring device 10 and moisture content monitoring device 11, and the data is fed back and updated in a timely manner on the mobile software. Users can set surface water level thresholds and soil moisture content thresholds in the mobile software according to the crops cultivated that year. When the water level of farmland 7 exceeds the surface water level threshold, an alert is issued to the user, and the automatic drainage function is activated, realizing a "monitoring-early warning-drainage" method based on the surface water level of farmland 7. When the soil moisture content is lower than the soil moisture content threshold, an alert is issued to the user, and corresponding irrigation suggestions are made in conjunction with the weather forecast for the next 7 days. Users can choose to start automatic irrigation or choose not to irrigate based on the rainfall situation for the next week, realizing a "monitoring-early warning-irrigation" method based on the soil moisture content of farmland 7.

[0066] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
