Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy, in particular to an intelligent water conservancy irrigation system. BACKGROUND

[0002] Water conservancy refers to various measures taken by human beings for the needs of survival and development to control and allocate water and water bodies in nature, so as to prevent and control flood and drought disasters, develop and utilize and protect water resources. Intelligent water conservancy is committed to improving the intelligent level of water conservancy planning, drainage and water supply and other social services, so that water resources can be used more efficiently, and plays a crucial role in the development of smart agriculture.

[0003] How to implement intelligent irrigation through intelligent water conservancy facilities to improve irrigation efficiency is an important issue in the development of smart agriculture.

[0035] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0036] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0037] This invention provides an intelligent irrigation system, such as... Figure 1 As shown, it includes:

[0038] Intelligent control equipment 101, water pump 102, water storage facility 103, and water diversion pipeline 104;

[0039] The intelligent control device 101 is used to control the water pump 102 to transport the water resources stored in the water storage facility 103 to the farmland 105 to be irrigated through the water diversion pipeline 104.

[0040] like Figure 3 As shown, the intelligent control device 101 includes: a parameter setting module 1011, a device status detection module 1012, a data storage module 1013, a data recovery module 1014, a delayed power-off module 1015, and a control module 1016;

[0041] The parameter setting module 1011 is used to receive irrigation parameter settings;

[0042] The device status detection module 1012 is used to detect the device status of the intelligent control device 101 in real time. When the device status of the intelligent control device 101 is detected to be abnormally closed, the control module 1016 controls the delayed power-off time of the delayed power-off module 1015. During the delayed power-off time, the irrigation parameters are read from the parameter setting module 1011 and stored in the data storage module 1013.

[0043] The device status detection module 1012 is further configured to, after detecting that the device status of the intelligent control device 101 is normal startup, read irrigation parameters from the data storage module 1013 through the data recovery module 1014, and synchronize the irrigation parameters to the parameter setting module 1011, so that when the irrigation parameters in the parameter setting module 1011 meet the preset irrigation conditions, the control module 1016 controls the water pump 102 to transport the water resources stored in the water storage facility 103 to the farmland to be irrigated 105 for water conservancy irrigation through the water diversion pipeline 104.

[0044] The parameter setting module 1011 is used to receive irrigation parameter settings. It can receive irrigation parameters manually input by users or maintenance engineers, irrigation parameters transmitted or imported by other devices via wireless, Bluetooth, USB, etc., and irrigation data transmitted by external sensors through the built-in wireless communication module. This embodiment of the invention does not impose specific limitations.

[0045] In this embodiment, irrigation parameters are typically saved to the data storage module 1013 according to a set cycle. The intelligent control device 101 has multiple states, including normal startup, normal shutdown, abnormal startup, and abnormal shutdown. When a sudden power outage or system power trips, the intelligent control device 101 may shut down abnormally. Often, irrigation parameters cannot be saved in time, requiring re-entry or re-collection of irrigation parameters after a normal restart, leading to unnecessary repetitive work. This solution controls the delayed power-off time of the delayed power-off module 1015 via the control module 1016. Power is only cut off to the intelligent control device 101 after the irrigation parameters have been successfully read and saved. This effectively solves the problem of irrigation parameters not being saved in time, being cleared, or being lost due to abnormal shutdown, thus effectively improving the reliability and intelligence level of the intelligent irrigation system and increasing operational efficiency.

[0046] The preset irrigation conditions can be a pre-set irrigation plan, which may include multiple irrigation parameters that can be set in advance in the parameter setting module 1011. When the corresponding preset irrigation conditions are met, water can be automatically diverted for irrigation without manual supervision or operation, effectively improving the automation level of agricultural irrigation. The water diversion pipeline can be a pre-constructed irrigation canal or ditch, or a temporary water pipe or other diversion facility. The corresponding water diversion pipelines are pre-numbered to facilitate advance planning of the water diversion route, ensuring that the water resources in the water storage facility 103 can be diverted to the corresponding farmland 105 to be irrigated.

[0047] Among them, water storage facility 103 can be a natural reservoir, a hydroelectric power station built later, a water storage pond, a water tank, or any other facility that can be used for water resource storage. Irrigated farmland can include any land that needs to be irrigated and used for planting plants, such as farmland, vegetable gardens, orchards, botanical gardens for ornamental purposes, flower beds in parks, etc.

[0048] In one exemplary embodiment, such as Figure 2 As shown, the intelligent irrigation system further includes: a pipeline booster device 106; the water diversion pipeline 104 includes various types of pipelines; the various types of pipelines include: vertical pipelines, horizontal pipelines and L-shaped pipelines, the L-shaped pipelines include: vertical pipes and horizontal pipes; wherein, the pipeline booster device 106 is installed on the horizontal pipeline, and / or on the horizontal pipe of the L-shaped pipeline.

[0049] Considering the varying distances between the farmland to be irrigated 105 and the water storage facility 103, and the uneven terrain, the water pressure in the water diversion pipeline 104 may drop after flowing a certain distance. In order to ensure the irrigation effect, a pipeline booster device 106 can be installed on the water diversion pipeline 104 to increase the water pressure and improve the irrigation effect.

[0050] In one embodiment, such as Figure 4 As shown, the pipeline pressurization device 106 includes: an elastic container 106a and a three-way valve 106b. The elastic container 106a includes an open end, and the three-way valve includes: an inlet, a first outlet, and a second outlet. The inlet is installed at one end of the horizontal pipeline and / or the L-shaped pipeline, the first outlet is installed at the other end of the horizontal pipeline and / or the L-shaped pipeline, and the second outlet is connected to the open end of the elastic container 106a. The inlet and the second outlet are kept normally open. By controlling the opening or closing of the first outlet, the flow direction of the water resources is controlled. Specifically, when the water resources flow from the inlet... When water enters the three-way valve 106b, the first outlet is closed. The water is injected into the elastic container 106a through the second outlet and the open end, compressing the air in the elastic container 106a. When the air pressure generated by the compressed air is balanced with the hydraulic pressure generated by the water in the elastic container 106a, the water injection into the elastic container 106a stops. Then, the first outlet is opened. Based on the air pressure generated by the compressed air, the water is pressurized and flows out of the elastic container 106a through the open end and the second outlet, and flows out towards the farmland 105 to be irrigated through the first outlet.

[0051] It should be noted that the elastic container 106a can be made of a material that can withstand a certain pressure, undergoes elastic deformation under pressure, and is not prone to rupture. The elastic container 106a has an open bottom (an open end) and is sealed at the rest. After being installed on the water supply pipe 104 via a three-way valve 106b, it forms a space for water supply flow between itself and the water supply pipe 104, preventing water leakage. To ensure balanced force distribution at all angles and extend the service life of the elastic container 106a, the shape of the elastic container 106a is preferably spherical. Compared to common shapes such as cubes, cylinders, and cones, the spherical shape of the elastic container 106a has been tested to increase its service life by more than 30%.

[0052] The elastic container 106a further includes a container body and a closed end. The closed end and the open end are located at opposite ends of the container body, and the closed end and the container body form a sealed space. The elastic container 106a is coupled to the second outlet of the three-way valve 106b through the open end, and is vertically installed on the horizontal pipe or the L-shaped pipe. After installation, the closed end of the elastic container 106a is located at the top, and the open end is located at the bottom. The distance between the open end and the horizontal plane is a first distance, and the distance between the horizontal pipe or the L-shaped pipe and the horizontal plane is a second distance, wherein the first distance is not less than the second distance. The distance between the closed end of the elastic container 106a and the horizontal plane is a third distance, and the distance between the highest point of the vertical pipe or the L-shaped pipe that is close to the water storage facility 103 and directly connected to the horizontal pipe or the L-shaped pipe and the horizontal plane is a fourth distance, wherein the third distance is not less than the fourth distance.

[0053] Preferably, the first distance is set to be greater than the second distance, which allows the open end to be positioned above the horizontal pipe or L-shaped pipe in the horizontal pipeline. This ensures that the pressurized water flows completely out of the elastic container 106a, improving the pressurization effect. The third distance is also preferably set to be greater than the fourth distance, which similarly improves the pressurization effect.

[0054] In another embodiment, to further enhance the pressurization effect, the aforementioned pipeline pressurization device 106 may further include an air-inflating component connected to the water intake pipe 104. The air-inflating component is preferably installed on the water intake pipe 104 connected to the inlet of the three-way valve 106b. The air-inflating component includes a side branch pipe, a switch valve, an opening, and a removable cap. The side branch pipe is directly connected to the water intake pipe 104, and its end has an opening with a removable cap. The switch valve is located between the end of the side branch pipe and the connection point with the water intake pipe 104. Under normal conditions, the cap is securely installed at the open end, ensuring that the side branch pipe and the water inlet pipe 104 are connected. When pressurization is required, first close the switch valve to cut off the water flow between the side branch pipe and the end opening and the water inlet pipe 104. Then, open the cap, connect an external air pump through the opening, and then open the switch valve to inflate the side branch pipe. The air pressure generated by the air pump pushes the water flow faster towards the three-way valve 106b, increasing the pressure generated by the water flow and thus effectively improving the pressurization effect. When the pressure meets the requirements, close the switch valve, remove the air pump, and install the cap back on the opening to restore normal operation.

[0055] It should be noted that the above-mentioned coupling connection can be achieved by threaded coupling, plug-in coupling, rotational coupling, etc. In this case, sealing can be achieved with the help of sealant, sealing gasket, etc., to ensure that the open end of the elastic container 106a is tightly connected to the second outlet of the three-way valve 106b, so that water leakage, overflow or spraying will not occur, and the pressurization can be effectively guaranteed.

[0056] In one embodiment, the pipeline booster device 106 further includes: a first timer, and the three-way valve is an electromagnetic three-way valve. Initially, the first outlet of the electromagnetic three-way valve is in an open state. The first timer is used to time the injection and outflow of water resources into the elastic container 106a, and sends a first trigger signal to the control module 1016 when the injection time reaches a first preset duration; and sends a second trigger signal to the control module 1016 when the outflow time reaches a second preset duration. When the control module 1016 detects that the water resources enter the electromagnetic three-way valve from the inlet, it controls the first outlet to close, so that the water resources are injected into the elastic container 106a through the second outlet and the open end. Upon receiving the first trigger signal from the first timer, the control module 1016 controls the first outlet to open, so that the water resource flows out of the elastic container 106a under pressure through the open end and the second outlet, and flows out towards the farmland 105 to be irrigated through the first outlet; upon receiving the second trigger signal from the first timer, the control module 1016 controls the first outlet to close, so that the water resource is injected into the elastic container 106a through the second outlet and the open end; wherein, the first preset duration is the time required for the water resource to start injecting and stop injecting into the elastic container 106a; the second preset duration is the time required for the water resource to start flowing out of the elastic container 106a and for all the water resource to flow out of the elastic container 106a.

[0057] In the above embodiment, by setting the three-way valve 106b as an electromagnetic three-way valve and setting a first timer that can time the injection and outflow of water resources, the first timer can communicate with the control module 1016. By feeding back the first trigger signal and the second trigger signal to the control module 1016, the inflow and outflow of water resources in the elastic container 106a can be fed back. For example, whether the water has reached a balance and no longer needs to be injected, or whether all the water resources have flowed out and need to be re-injected. This allows the control module 1016 to control the opening or closing of the first outlet in a timely manner, thereby realizing the automatic cyclic pressurization of the pipeline pressurization device 106 and effectively improving the intelligence level of the system.

[0058] The first and second preset durations can be determined in advance through experiments or calculations. The first preset duration ensures that water flows from the initial injection into the elastic container 106a until it reaches a balanced state and stops flowing. The second preset duration ensures that water flows from the initial outflow into the elastic container 106a until it completely flows out. The specific settings for the first and second preset durations need to be based on the water flow rate in the electromagnetic three-way valve, water pressure, the second outlet, the size of the elastic container opening, and the size of the elastic container. If any of these parameters changes, the first and second preset durations need to be recalculated or re-tested.

[0059] In another embodiment, such as Figure 2 As shown, the intelligent irrigation system further includes: a first power supply 107 for supplying power to the intelligent irrigation system; the delayed power-off module 1015 includes: a delayed relay 1015a, a second timer 1015b, and a second power supply 1015c; the second power supply 1015c is different from and independent of the first power supply 107, and supplies power to the intelligent control device 101; the second power supply 1015c includes at least one of the following types: a storage battery, a solar power battery, and a hydroelectric power battery; wherein, the delayed... The delayed power-off time of the time relay 1015a is set based on the first time required to read irrigation parameters from the parameter setting module 1011 and the second time required to store the irrigation parameters to the data storage module 1013, and the delayed power-off time is not less than the sum of the first time and the second time; after detecting that the intelligent control device 101 is abnormally shut down, the second timer 1015b starts timing, and when the timing time reaches the delayed power-off time, the control module 1016 controls the delayed power-off module 1015 to cut off the second power supply 1015c.

[0060] It should be noted that the type of the second power supply 1015c can be determined based on the geographical location of the intelligent irrigation system; wherein, when the sunlight conditions of the geographical location reach the preset sunlight conditions, the type of the second power supply is determined to be a solar power battery; when the geographical location has a river with a height difference reaching the first preset height threshold, or when the water storage facilities of the geographical location include multi-level water stations, and the height difference between any two adjacent water stations reaches the second preset height threshold, the type of the second power supply is determined to be a hydroelectric power battery.

[0061] Considering that intelligent irrigation systems are often located in rural areas far from urban centers, if the local geographical environment has abundant sunlight, solar energy storage modules can be pre-installed to convert solar energy into electrical energy for storage, serving as a secondary power source for the intelligent control device 101. If the local geographical environment has rivers, waterfalls, or other features with significant elevation differences, or if the water storage facility itself contains multiple water stations with large elevation differences between adjacent stations, these conditions can be fully utilized to implement hydroelectric power generation, converting the potential energy generated by the water flow difference into electrical energy as a secondary power source. If the local geographical location does not meet any of the above conditions, batteries can be used as a secondary power source.

[0062] like Figure 3 As shown, the intelligent control device 101 in the above embodiment may further include: a device switch 1017, which is used to control the normal start-up and normal shutdown of the intelligent control device 101; a device status detection module 1012 is used to collect the switch status of the device switch 1017; the intelligent control device 101 is provided with at least one preset detection point near the inlet side of the first power supply 107, and the device status detection module 1012 is also used to collect voltage signals from the preset detection points; wherein, when the voltage signal collected by the device status detection module 1012 disappears or is lower than the preset voltage value, and the device switch 1017 is in the closed state, it is determined that the device status of the intelligent control device 101 is abnormally closed.

[0063] In an optional embodiment, when the data storage module 1013 stores multiple historical irrigation parameters, the data recovery module 1014 reads the latest irrigation parameters from the data storage module 1013.

[0064] The irrigation parameters include: a first irrigation parameter; the intelligent control device 101 further includes: a meteorological information acquisition module, a soil information acquisition module, an environmental information acquisition module, multiple sensors, and a computing module; the multiple sensors include: a first sensor and a second sensor, the first sensor being set at multiple different locations on the farmland to be irrigated to collect soil temperature and humidity information of the farmland to be irrigated, and the second sensor being set at multiple different locations in the surrounding environment of the farmland to be irrigated to collect environmental information within a preset range around the farmland to be irrigated;
