Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation technology, specifically to a distributed farmland water conveyance pipeline based on the Internet of Things. Background Technology

[0002] Farmland irrigation refers to the artificial introduction of water resources into farmland to supplement insufficient natural rainfall or optimize water distribution, thereby meeting the water requirements for crop growth and ensuring the stability and efficiency of agricultural production. Its core purpose is to increase crop yield and improve quality through scientific water management, and to promote the sustainable use of land resources.

[0003] However, most existing irrigation systems operate on a unified switch. During the planting process, different areas of farmland experience varying degrees of water shortage. Existing irrigation devices cannot irrigate individually based on the water shortage level of the soil in each area, nor can they precisely control soil moisture. This can potentially cause water stress or waterlogging disasters on farmland, a problem that urgently needs to be solved by researchers in this field. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 The present invention provides a technical solution: a distributed farmland water supply pipeline based on the Internet of Things, including a water tank 1 and a controller 15, wherein the water tank 1 is connected to a water supply pipe 18, and an intelligent water replenishment unit is provided on the water supply pipe 18.

[0019] The intelligent water replenishment unit includes a soil moisture monitoring module and a water supply module;

[0020] The soil moisture monitoring module includes a soil moisture monitor 7, which is distributed and deployed in different areas of farmland. The soil moisture monitor 7 is connected to the controller 15 through a LoRa wireless gateway 6.

[0021] The water supply module includes a first water pump 2, which is connected to the water tank 1 via a water supply pipe 18. A third solenoid valve 12 is connected to the water supply pipe 18 via a three-way pipe 11. An irrigation connector 13 is connected to the outlet of the third solenoid valve 12.

[0022] Among them, the LoRa wireless gateway 6 is a core communication device based on LoRa technology in the Internet of Things (IoT), responsible for establishing a long-distance, low-power wireless data transmission link between terminal sensors and the cloud platform.

[0023] It should be noted that the soil moisture monitor 7 is a mature existing technology. The soil moisture monitor 7 detects the soil through a capacitive humidity sensor built into it. Its detection depth is 10-50cm, and the data sampling frequency is 1-10 minutes / time. The data is uploaded to the controller 15 through the LoRa wireless gateway 6. The standard value of the required humidity of farmland soil is measured and built into the controller 15 as reference data. The method of measuring the standard value of soil humidity will not be described in detail in this application.

[0024] It should be added that the third solenoid valve 12 is a mature existing technology, which is mainly used for precise control of irrigation water flow, and will not be described in detail in this application.

[0025] refer to Figure 1The first water pump 2 pumps water from the pool 1 to the water pipe 18. Then, the water pipe 18 and the third solenoid valve 12 are used to replenish water for irrigation in areas where the soil moisture is lower than the standard value. The irrigation connector 13 can be connected to an external drip irrigation pipe or sprinkler irrigation pipe.

[0026] The outlet of the first water pump 2 is connected to a filter 3 via a water pipe 18. The outlet of the filter 3 is connected to another section of the water pipe 18. A second solenoid valve 5 is fixedly connected to the water pipe 18. The second solenoid valve 5 is network-connected to the controller 15.

[0027] It should be noted that filter 3 is a sand filter, which filters impurities in water by adsorbing and retaining suspended solids through a quartz sand layer. This will not be elaborated on further in this application.

[0028] It should be added that the second solenoid valve 5 is a mature existing technology, which is mainly used for precise control of irrigation water flow, and will not be described in detail in this application.

[0029] refer to Figure 1 The filter 3 is installed between the first water pump 2 and the second solenoid valve 5, which can effectively prevent impurities in the water from clogging the second solenoid valve 5. The controller 15 is used to control the opening and closing of the second solenoid valve 5.

[0030] A water-fertilizer mixing module is provided on the water supply pipe 18. The water-fertilizer mixing module includes a first branch pipe 181, which is connected to the water supply pipe 18. A first solenoid valve 4 is fixedly connected to the first branch pipe 181. The end of the first solenoid valve 4 away from the water supply pipe 18 is connected to a fertilizer tank 8. The fertilizer tank 8 is connected to a water-fertilizer integrated machine 9. The water outlet of the water-fertilizer integrated machine 9 is connected to a second water pump 10. The water outlet of the second water pump 10 is connected to the water supply pipe 18 through a second branch pipe 182.

[0031] It should be noted that the integrated water and fertilizer machine 9 is existing technology. The integrated water and fertilizer machine 9 achieves efficient and uniform mixing of water and fertilizer through precise control, mechanical mixing and intelligent linkage. Its core principle is to inject soluble solid or liquid fertilizer into irrigation water according to a preset ratio to form a uniform water and fertilizer mixture, which is then transported to the crop roots through the water supply network. This application will not elaborate further.

[0032] It should be added that the first solenoid valve 4 is a mature existing technology, which is mainly used for precise control of irrigation water flow, and will not be described in detail in this application.

[0033] refer to Figure 1The first branch pipe 181 is installed between the second solenoid valve 5 and the filter 3. The first solenoid valve 4 is used to control whether the water needs to pass through the first branch pipe 181 to enter the fertilizer tank 8. The second delivery water pump 10 is used to pump the mixed water and fertilizer solution in the water and fertilizer machine 9 to the delivery pipe 18.

[0034] A fixing rod 14 is fixedly connected to one side of the water tank 1. The controller 15 is fixedly installed on the fixing rod 14. A photovoltaic panel 16 is fixedly connected to the fixing rod 14. The photovoltaic panel 16 is electrically connected to the controller 15 through an inverter.

[0035] refer to Figure 1 A battery (not shown in the figure) and an inverter (not shown in the figure) are installed on the fixed rod 14. The photovoltaic panel 16 collects solar energy and converts it into electrical energy through the inverter and stores it in the battery. This energy is used to power the controller 15 and other electrical components, thereby achieving energy saving and emission reduction.

[0036] A monitoring camera 17 is fixedly connected to the top of the fixed rod 14. The monitoring camera 17 is connected to the controller 15 through the LoRa wireless gateway 6.

[0037] The surveillance camera 17 can monitor various areas of the farmland in real time. By using the surveillance camera 17 to communicate with the controller 15 through the LoRa wireless gateway 6, the situation in the farmland can be observed remotely, making it easier to deal with various emergencies.

[0038] The working principle is as follows: Soil moisture monitoring devices 7 are fixedly installed in various areas of the farmland. When a soil moisture monitoring device 7 detects that the soil moisture content at a certain location is lower than the standard value built into the controller 15, the soil moisture monitoring device 7 sends the monitoring signal to the controller 15 through the LoRa wireless gateway 6. At this time, the controller 15 controls the first water pump 2 to start. The first water pump 2 delivers water from the pool to its end through the water pipe 18. Then, through the irrigation connector 13, it can be connected to drip irrigation or sprinkler irrigation pipes. By controlling the opening of the third solenoid valve 12 on the three-way pipe 11 at that location, water is supplied to the farmland soil. After a period of time, when the soil moisture monitoring device 7 detects that the soil moisture content at that location has reached the standard value built into the controller 15, irrigation can be stopped.
