The corrosion resistance of inorganic materials and some polymer materials in soil and acid rainwater has yet to be solved. In extreme weather such as hail and typhoons, the equipment safety cannot be guaranteed and needs to be moved indoors. (Hail can damage solar panels, causing charging to be destroyed and the equipment to lose power; since the fixation is only suitable for basic support, it cannot resist typhoon winds). Utility Model Content

[0003] In order to solve the above problems, the utility model provides an agricultural water-fertilizer integrated irrigation intelligent control device.

[0004] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: an agricultural water-fertilizer integrated irrigation intelligent control device, including a main system solar panel, a main system shell, an electric valve control switch, a pipeline connection, a valve, a flow meter, a main system shell connection seal and a measuring device.

[0008] The utility model adopts the above structure to achieve the following beneficial effects:

[0009] The utility model provides an agricultural water-fertilizer integrated irrigation intelligent control device:

[0010] 1) The master and slave devices are separated to ensure the corresponding irrigation range;

[0011] 2) The device does not need to be manually charged, and solar power can last for a long time;

[0012] 3) The equipment cost is relatively low and the warranty period is long;

[0013] 4) The manual and automatic modes of this system can be switched freely. When the device is used for the first time, the default device is the automatic mode to switch the valve. If manual operation is required later, it can be switched to manual mode in the APP. During use, the manual mode command is higher than the automatic mode command. The user can turn on the manual mode to open or close the valve at any time. If the system automatically determines that its manual operation is unreasonable in manual mode, a prompt will pop up in the APP to prevent problems such as wrong opening and wrong closing in manual operation. In automatic mode, the system can automatically determine the moisture and nitrogen, phosphorus and potassium required by crops based on the data uploaded from the device, and automatically control the water pump switch and the water-fertilizer integrated equipment to perform corresponding operations. When the moisture, nitrogen, phosphorus and potassium content reaches the set value, the water pump and water-fertilizer integrated equipment will automatically stop working. There will be three levels of response speed in the automatic control mode. The first level has the fastest response speed, with an error of 1%; the second level has a slower response speed, with an error of 5%; the third level has the slowest response speed, with an error of 10%.

[0014] 5) If the device fails or the user operates improperly, a warning will pop up in the APP to inform the user of the problem and propose a corresponding solution;

[0015] 6) The APP has an anti-theft mode. When this mode is turned on, if the device is abnormally moved, the APP will contact the terminal, and the service center robot will call the account registrant to inform the corresponding situation;

[0016] 7) If the ambient temperature reaches the upper limit of the temperature suitable for watering the crops, it will be unfavorable for watering and fertilizing the crops, and all valves will be closed. Wait until the temperature drops to a suitable level before continuing to work. Usually, all valves are closed when the temperature is above 35°C. If the crop planting situation is special, the upper limit of the temperature can be adjusted in the APP;

[0017] 8) There is a manual buckle on the valve body. If the equipment fails, the manual buckle pipe valve can be used directly to avoid greater losses;

[0018] 9) When the device is occupied by scanning the code, other users cannot connect to the device. However, the device can be shared by one person, and two people can use the device together during the sharing period. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] like Figure 1 and Figure 2As shown, the utility model proposes an agricultural water-fertilizer integrated irrigation intelligent control device, including a main system solar panel 1, a main system housing 2, an electric valve control switch 3, a pipeline connection 4, a valve 5, a flow meter 6, a main system housing connection seal 7 and a measuring device. A control chip structure is provided in the main system housing 2, and the main system solar panel 1 is embedded and installed in the main system housing 2. A 6V 7W solar panel is used, and the size is 17.5×19.5cm. While ensuring the minimum area, the charging is maximized. Under sufficient sunlight, the charging current can reach 1A. The solar panel of the device can meet the power consumption of the valve body under charging. The electric valve control switch 3 is arranged in the main system housing 2. The main system housing connection seal 7 is arranged under the electric valve control switch 3 and forms a sealed cavity structure with the main system housing 2. The valve 5 is arranged under the main system housing connection seal 7. The valve body is a straight-through ball valve. The valve body channel is flat and smooth, and impurities are not easy to deposit. Because the motor 8 equipped has a large torque, fine particles are allowed to pass through. The pipeline connection is symmetrically arranged on both sides of the valve 5. The flowmeter 6 is connected to the side of the valve body. The large-caliber Hall flowmeter 6 is installed at the water outlet of the valve body, and one end with a thread can be directly rotated and connected to the valve body. The other end is connected to the main pipeline and is clamped with a hand-tightened double steel wire clamp. A sealed Grange fixed lock connector is installed at the connection between the flowmeter 6 and the valve body to prevent liquid from entering the main device. The measuring device is wirelessly connected to the control chip structure in the main system housing 2.

[0025] Furthermore, the electric valve control switch 3 includes a motor 8, an output shaft 9, a reduction gear set 10 and a reduction gear housing 11. The reduction gear housing 11 is inside the main system housing 2. The motor 8 is arranged at the top of the reduction gear housing 11. The motor 8 adopts the principle of a two-wire electric two-way ball valve, a gearbox transmission, and a copper gear linkage, and can be powered for a long time. The torque of the motor 8 is 8 Nm. When the water inlet pressure is too large, the greater the torque of the motor 8, the easier it is to open the water valve connected thereto, and the pipe bursting problem caused by the switch valve not being in place is prevented. A connection groove for installing the motor 8 is reserved on the housing of the main equipment. The two are fixed with neutral silicone weather-resistant glue. In order to ensure that the rotation angle of the reduction motor 8 is 90°, a 90° limiter is installed in the body to ensure that the motor 8 twists the angle so that the valve body can be tightly opened and closed. The reduction gear set 10 is arranged in the reduction gear housing 11, and the reduction gear set 10 is respectively connected to the drive motor 8 and the valve 5.

[0026] Furthermore, the measuring device includes a measuring system solar panel 12, a threaded connection pipe 13, a fixed pipe 14 and a soil sensor 15. A main control circuit board and a battery are arranged in the housing of the measuring device. The measuring system solar panel 12 is arranged on the threaded connection pipe 13, and the fixed pipe 14 is arranged under the threaded connection pipe 13. The fixed pipe 14 is a PVC pipe. The PVC pipe is mainly used to set up the slave machine. The slave machine is set up at a position higher than the crops so as to fully receive light and provide sufficient power for the slave device. At the same time, the PVC pipe can effectively prevent animals such as mice and snakes from gnawing on the sensor connection line to ensure stable upload of slave data. The slave device is pre-threaded, and the PVC pipe can be fixed to the housing of the slave device by a knob to prevent water seepage and falling off. The soil sensor 15 is arranged under the fixed pipe 14. The soil sensor 15 mainly measures the soil water content, nitrogen, phosphorus and potassium content. The imported 316 stainless steel probe is used for high-temperature vacuum canning with high-density epoxy resin between the body, which can prevent moisture from entering the body and has good sealing performance. The waterproof and dustproof level can reach IP67. The soil sensor 15 and the slave device adopt a split design. The connection ports of the two use aviation male and female connectors. This connection method can ensure that users can correctly connect phases A and B, and will not cause damage to the sensor due to misconnection. The depth of the sensor placed in the soil is determined by the growth of the crop root system, and the APP will have a recommended burial value.

[0027] The communication method between the measuring device and the main system housing 2 is LoRa communication.

[0028] When used, this product consists of three parts: the main device, the slave device, and the APP. The three parts work together to complete fully automatic farmland irrigation. The main device is installed above the valve body where the pipeline is laid, and the reduction motor 8 drives the valve body switch to control the start and stop of the water valve; the slave device is installed in the most water-deficient place within 1km from the main device, monitors soil data and uploads it to the main device to assist the main device in normal operation.

[0029] When using it, users need to download the APP independently developed by our company to select the crop varieties to be planted. The system will automatically match the optimal soil moisture content, optimal nitrogen, phosphorus, and potassium ratios for the corresponding crops. After the settings are completed, you can wait for the system to work on its own. If the user has special requirements for moisture content, nitrogen, phosphorus, and potassium, the corresponding values ​​can be set manually.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
