Description

Technical Field

[0001] The present invention relates to the technical field of intelligent control of farmland irrigation, and in particular to intelligent control equipment and a control method for farmland irrigation. Background Art

[0002] At present, water conservancy projects built in various places to ensure harvests during drought and flood can all achieve increased and stable yields of crops, but irrigation is generally controlled manually, and the effective utilization rate of irrigation water is low, resulting in a waste of water resources, and consuming manpower, which is not conducive to management; this type of irrigation is simple and convenient to operate, with low labor intensity, and can complete the application of pesticides and fertilizers to crops while irrigating the farmland, and has a positive promotion significance in agricultural production. Some existing drip irrigation systems are equipped with pipes on the surface of the farmland, and the pipes have water holes. Water flows through the pipes and flows out of the water holes, so that the water can enter the soil of the farmland to moisturize the crops in the soil and achieve the effect of irrigation. This method is simple and convenient to operate, saves time and effort, and has been widely promoted and used.

[0003] However, during the watering process, the moisture content in the soil under the crops cannot be known in time, and irrigation is only based on fixed intervals. This watering method that relies solely on experience is obviously unscientific. If the humidity in the soil is high and watering is still carried out, the crops can easily be drowned, causing great harm to the crops; if the soil is relatively dry, but there is no timely watering, the crops are prone to lack of water and cause poor growth, which will also cause a reduction in crop yields.

The first nozzle 132 is arranged at the intersection of the upper surface of the long pipe 1 and the joint pipe 131 . The second nozzle 141 is spaced uniformly from two adjacent first nozzles 132 .

[0044] A first solenoid valve 133 is provided at the inlet position of the first nozzle 132, and a second solenoid valve 142 is provided at the inlet position of the second nozzle 141. The control cabinet 2 signals connect the first solenoid valve 133 and the second solenoid valve 142.

[0048] The upper surfaces of the first nozzle 132 and the second nozzle 141 are both provided with spray holes, and the plurality of spray holes are evenly distributed around the upper surfaces of the first nozzle 132 and the second nozzle 141 at equal intervals. The two ends of the short pipe 14 are respectively plugged into the two ends of the connecting pipe 131. The first valve 12 is a manual valve, and the first valve 12 is convenient for manual operation.

[0049] A plurality of plug rods 23 are vertically arranged on the lower surface of the long pipe 13, and the upper ends of the plug rods 23 are fixed at the intersection of the lower surface of the long pipe 13 and the plug tube 131. The plug rods 23 are evenly distributed along the length direction of the lower surface of the long pipe 13 at equal intervals. A humidity sensor 24 is arranged at the lower end of the plug rod 23. A cavity is arranged inside the plug rod 23, and a wire hole is arranged above the surface of the plug rod 23. The wire hole is connected to the cavity. The signal line of the humidity sensor 24 is located in the cavity and connected to the control cabinet 2 through the wire hole.

[0050] A control method using an intelligent control device for farmland irrigation comprises the following steps:

[0051] S1, installing a plurality of short pipes 131 between two adjacent joint pipes 131, and placing the spliced ​​main pipe 1, liquid pump 11, and short pipe 14 horizontally on a crop planting field;

[0052] S2, pressing the rod 23 toward the soil of the planting field, so that the rod 23 enters the inside of the soil, so that the humidity sensor 24 is located inside the soil;

[0053] S3, numbering each humidity sensor 24, numbering the first solenoid valve 133 and the second solenoid valve 142 around each humidity sensor 24, and inputting them into the control cabinet 2;

[0054] S4. When the humidity sensor 24 detects that the interior of the soil is relatively dry, the first solenoid valve 133 and the second solenoid valve 142 around the humidity sensor 24 are opened, and water is sprayed from the first nozzle 132 and the second nozzle 141 at that position to irrigate the soil at the dry position.

[0055] In summary: the entire device can be set up according to farmland plots of different sizes, with multiple long pipes 13 in parallel and multiple short pipes 14 located between the long pipes 13, so that the farmland plots can be better divided into small areas, and the crops grow upward in the space between the long pipes 13 and the short pipes 14;

[0056] When the liquid pump 11 is working, the water from the water source can be sent into the main pipe 1. The water in the main pipe 1 can flow into the long pipe 13. The water in the long pipe 13 can enter the short pipe 14 through the plug pipe 131. In this way, all the long pipes 13 and the short pipes 14 are filled with water. When the first solenoid valve 133 and the second solenoid valve 142 are opened, the water in the long pipe 13 and the short pipe 14 can be sprayed out from the first nozzle 132 and the second nozzle 141 to irrigate the crops growing on the farmland.

[0057] Under the action of the insertion rod 23, the humidity sensor 24 can be located at a deeper position in the soil. The humidity sensor 24 detects the humidity deep inside the soil in real time. When a humidity sensor 24 detects that the soil is relatively dry, it can transmit a signal to the control cabinet 2. The control cabinet 2 can open the first solenoid valve 133 on the first nozzle 132 and the second solenoid valve 142 on the second nozzle 141 around the humidity sensor 24, so that water can be sprayed from the first nozzle 132 and the second nozzle 141 to splash onto the surrounding soil to irrigate crops;

[0058] The water flows downward along the soil. When the humidity sensor 24 detects that the humidity of the soil reaches the standard, it can transmit a signal to the control cabinet 2. The control cabinet 2 can control the electromagnetic valve 133 on the first nozzle 132 and the second electromagnetic valve 142 on the second nozzle 141 around the humidity sensor 24 to close. In this way, water will not be sprayed from the first nozzle 132 and the second nozzle 141, thereby avoiding excessive watering.

[0059] By using the humidity sensor 24 to detect the humidity inside the soil in real time, it is possible to irrigate more accurately and quantitatively, thus playing a role in intelligent regulation.
