[0044] The implementation of the embodiments will be described in detail below with reference to the accompanying drawings.

[0045] The embodiments provide a drip irrigation control method, which can monitor the activity of each business function of an application, and provide data reference for maintaining and updating the application.

[0046] Figure 1 A structure diagram of a drip irrigation controller provided by an embodiment of the present application is shown.

[0047] As shown in Figure 1 , the drip irrigation controller can include the following:

[0048] The communication chip 10 provides multiple communication interfaces, and the communication distance is greater than 4000 meters;

[0049] The first communication interface is in communication connection with the sensor 11, and the soil state data collected by the sensor 11 is acquired.

[0050] The at least two second communication interfaces are respectively in communication connection with an electromagnetic valve (i.e., the electromagnetic valve 12 and the electromagnetic valve 13) to control the valve state of the electromagnetic valve.

[0051] The valve state of the electromagnetic valve is acquired through the second communication interface.

[0052] The communication chip of the present application includes multiple communication interfaces, which can synchronously collect soil temperature and humidity and other information, and the one-to-two design (one device controls two electromagnetic valves) further reduces the use cost of the user.

[0053] Exemplarily, the first communication interface can be multiple, which can be connected with soil, weather, water pressure, water flow and other sensors, so as to synchronously collect multiple sensor data, i.e., soil state data. Specifically, the soil state data can include soil humidity, soil temperature, nitrogen, phosphorus and potassium content of soil, etc.

[0054] The communication chip 10 can be a WH-L101-L chip, which can support a communication distance of 5km, and the usable range is larger. In this embodiment, a 5km communication distance high-power chip is used, which reduces the delay under the condition of increasing the communication distance, the device does not enter the sleep mode throughout the whole process, and the possibility of losing data due to wake-up is reduced.

[0055] The second communication interface includes at least two communication interfaces, which are respectively connected with the electromagnetic valve 12 and the electromagnetic valve 13. The second communication interface sends instructions to the electromagnetic valve 12 and the electromagnetic valve 13 to control the valve state of the electromagnetic valve 12 and the electromagnetic valve 13, and acquires the valve state of the electromagnetic valve 12 and the electromagnetic valve 13.

[0056] In an exemplary embodiment, the communication chip further includes a third communication interface, the third communication interface of the communication chip is in communication connection with the communication controller 14, and sends a heartbeat data packet to the communication controller 14, wherein the heartbeat data packet includes the soil state data.

[0057] In an exemplary embodiment, the control instructions for the electromagnetic valve 12 and the electromagnetic valve 13 sent by the communication controller 14 are received through the third communication interface; and the valve state of the electromagnetic valve 12 and the electromagnetic valve 13 is returned to the communication controller 14 through the third communication interface.

[0060] In order to provide higher power for the WH-L101-L chip, the voltage of the power supply needs to be boosted and then input into the WH-L101-L chip. In order to balance the boosted voltage of the WH-L101-L chip, the boosted voltage is used to output a pulse control signal for the electromagnetic valve 12 and the electromagnetic valve 13, so as to improve the strength of the pulse control signal while balancing the higher power consumption and reducing power waste.

[0061] It can be understood that the drip irrigation controller can further include other modules, such as a solar power supply module, a communication module, etc., and the embodiment is not limited thereto. The drip irrigation controller of the embodiment has a simple structure, adopts an integrated lightweight design, is convenient to install, has no complex installation process, and can reduce labor costs.

[0062] The embodiment also provides a drip irrigation control method based on the drip irrigation controller. The drip irrigation control method can be applied to various electronic devices such as a computer (PC), a tablet computer, a virtual reality / augmented reality device, a wearable device, an industrial computer, and a car machine. The drip irrigation control method can also be applied to a server, a cloud, and a server cluster, and the embodiment is not specially limited thereto.

[0063] Hereinafter, the drip irrigation control method executed on a PC is taken as an example.

[0064] As shown in Figure 2 , the drip irrigation control method comprises the following steps.

[0065] Step 201: receiving soil state data sent by the drip irrigation controller, wherein the drip irrigation controller is connected with at least two electromagnetic valves.

[0066] Step 202: determining whether the soil state data is abnormal, and in the case that the soil state data is abnormal, sending a drip irrigation control instruction to the drip irrigation controller to control the drip irrigation controller to open the electromagnetic valves for irrigation.

[0067] The structure of the drip irrigation controller can refer to Figure 1 , and details are not described herein. The drip irrigation controller of the embodiment has a communication distance of at least 4000 meters, which can improve communication effectiveness and thus improve the usability and effectiveness of drip irrigation control.

[0068] In the drip irrigation control method of the embodiment, the PC end can automatically send an instruction to the drip irrigation controller to control the drip irrigation controller to open the electromagnetic valve for irrigation in the case of determining that the soil state data is abnormal, thereby improving the timeliness of irrigation. Each drip irrigation controller can control at least two electromagnetic valves, thereby improving the control efficiency, reducing the power consumption of the drip irrigation controller, and reducing the cost.

[0069] The drip irrigation control instruction is used to instruct the drip irrigation controller to perform irrigation.

[0070] The PC end can be connected with a communication interface provided by the drip irrigation controller, so as to acquire the soil state data on the drip irrigation controller through the communication interface.

[0071] Exemplarily, the soil state data includes soil temperature and humidity, and the determination of whether the soil state data is normal includes:

[0072] determining whether the soil temperature and humidity are lower than a first preset value, and determining that the soil state data is abnormal when the soil temperature and humidity are lower than the first preset value.

[0073] Exemplarily, the soil state data includes soil nitrogen, phosphorus and potassium content, and the determination of whether the soil state data is normal includes:

[0074] determining whether the soil nitrogen, phosphorus and potassium content is lower than a second preset value, and determining that the soil state data is abnormal when the soil nitrogen, phosphorus and potassium content is lower than the second preset value.

[0075] In the embodiment, the PC end sends a drip irrigation control instruction to the drip irrigation controller to control the drip irrigation controller to open the electromagnetic valve for irrigation, which includes: sending a drip irrigation controller instruction to the drip irrigation controller to make the drip irrigation controller open the electromagnetic valve; acquiring a valve state through the drip irrigation controller, the valve being used to indicate that the electromagnetic valve is opened or closed; and sending an opening pump instruction to the drip irrigation controller to make the drip irrigation controller open the water pump when the valve state is open.

[0076] The PC end can send a drip irrigation control instruction to the drip irrigation controller through a communication interface provided by the drip irrigation controller. When the drip irrigation controller receives the drip irrigation control instruction, the connected electromagnetic valve can be controlled to be opened, and the valve state of the electromagnetic valve is acquired. When the valve state of the electromagnetic valve is open, the water pump is controlled to be opened. The embodiment increases the electromagnetic valve state reading function, the PC end sends an instruction, and the electromagnetic valve state is collected and fed back in real time, so that the electromagnetic valve is opened first and then the water pump is opened, thereby preventing the water pump from being damaged and causing loss, and improving the effectiveness of the control instruction.

[0077] Specifically, the irrigation control instruction can include an irrigation instruction and a water and fertilizer application instruction. When the soil temperature and humidity is lower than a first preset value, an irrigation instruction can be sent to the drip irrigation controller, the irrigation instruction being used to instruct the drip irrigation controller to irrigate. When the drip irrigation controller receives the irrigation instruction, two electromagnetic valves connected thereto can be opened, and the water pump can be started to irrigate after the electromagnetic valves are opened.

[0078] When the soil nitrogen, phosphorus and potassium content is lower than a second preset value, a water and fertilizer application instruction can be sent to the drip irrigation controller, the water and fertilizer application instruction being used to instruct the drip irrigation controller to apply water and fertilizer. When the drip irrigation controller receives the water and fertilizer application instruction, two electromagnetic valves connected thereto can be opened, and the water pump and the water and fertilizer applicator can be started after the electromagnetic valves are opened.

[0079] Figure 3 An application scenario of the drip irrigation control method is shown. As shown in Figure 3 For example, a plurality of drip irrigation controllers, such as drip irrigation controller 31, drip irrigation controller 32, drip irrigation controller 33, drip irrigation controller 34, etc., can be arranged in a field or a farm. A communication controller 35 is connected to each drip irrigation controller. A PC terminal 30 can be connected to the communication controller 35, and data transmission can be performed between the PC terminal 30 and the drip irrigation controllers 31, 32, 33 and 34 through the communication controller 35.

[0080] Specifically, the PC terminal 30 receives the soil state data sent by the drip irrigation controllers 31, 32, 33 and 34 through the communication controller 35, and sends the drip irrigation control instruction to the drip irrigation controllers 31, 32, 33 and 34 through the communication controller 35. For example, when the PC terminal 30 determines that the soil state data sent by the drip irrigation controller 31 is abnormal, the drip irrigation control instruction can be sent to the drip irrigation controller 31 to open the electromagnetic valves 311 and 312.

[0081] Further, the embodiment also provides a drip irrigation control device which can be used to execute the drip irrigation control method. As shown in Figure 4 The drip irrigation control device 40 specifically includes the following:

[0083] The instruction control module 42 is used to determine whether the soil state data is abnormal. When the soil state data is abnormal, the drip irrigation control instruction is sent to the drip irrigation controller to control the drip irrigation controller to open the electromagnetic valves to irrigate.
