[0096] During specific use, refer to Figure 1 and Figure 2 As shown, the operator inputs the type and model information of the water and fertilizer integrated machine on the user interface module and selects a specific device number. These information are sent to the data processing module through the signal processing module for preliminary processing and displayed on the user interface for the operator to confirm.

[0097] According to the location numbers of each water and fertilizer integrated machine in the planting area, the information acquisition module collects real-time data from the soil moisture detection module and the soil salinity detection module. The data of the soil internal humidity and salinity content are transmitted to the data processing module via the wireless transmission module. After receiving the humidity and salinity data, the data processing module analyzes and processes them and sends the results back to the user interface module. The user interface module displays that the current soil condition is a humidity of 60% and a salinity of 0.5 g / kg, and compares it with the preset standard values, a humidity of 70% and a salinity of 0.4 g / kg, to decide whether to start irrigation or fertilization operations. If the soil internal humidity is lower than the externally set value, the automatic irrigation module is triggered to start working; otherwise, irrigation is stopped. If the detected soil humidity is 45%, lower than the standard value of 70%, the system will automatically turn on the irrigation to supplement water.

[0098] When the soil salinity is higher than the standard, the system will instruct the fertilizer automatic supply module to add an appropriate amount of fertilizer; if the salinity is appropriate, no action is taken. The soil salinity is 0.8 g / kg, exceeding the standard value of 0.4 g / kg. The system may calculate that a certain amount of nitrogen fertilizer needs to be added to adjust the soil composition. The user interface module can receive the fertilizer supplement or non-fertilizer supplement instructions from the user and convert them into digital signals, which are conveyed to the corresponding execution module through the wireless transmission module. The automatic supply module controls the power state through a switch according to the received signal to achieve fertilizer supply or stop.

[0099] The user can set the water pressure parameters through the user interface, and set the standard water pressure to 3 bar. The system will selectively start the low-pressure pump or the high-pressure pump according to the actually measured water pressure value to maintain the required pressure level. If the external water pressure is 4 bar, and the external water pressure is greater than the standard water pressure, the system will choose to turn off the high-pressure pump and start the low-pressure pump; in the opposite case, the high-pressure pump will be started. During the whole process, the information acquisition module continuously sends the latest internal and external soil information to the data processing module, and the latter outputs new control instructions accordingly to ensure the dynamic responsiveness and accuracy of the system. The results of all operations will be updated in real time on the user interface so that the operator can view them at any time and give further instructions.

Detect the salt content inside the soil through the soil salt detection module, and send the salt content inside the soil to the data processing module through the wireless transmission module; S5.2, processing the data of the internal salt of the soil through the data processing module; S5.3, the data processing module sends the processed soil internal salt information results to the user interface module, and the user interface module compares the internal salt content index with the external salt content index; S5.4, if the internal salt content is greater than the external salt content, the user interface module sends the information to the information collection module, the information collection module sends the information to the automatic fertilizer replenishment module, the automatic fertilizer replenishment module turns on the power supply, and performs the automatic soil fertilization operation; S5.

5. If the internal salt content is less than the external salt content, the user interface module sends the information to the information collection module, and the information collection module sends the information to the stop fertilization module, and the stop fertilization module stops the fertilization operation.

8. The method of a smart agricultural water-fertilizer integrated machine based on intelligent control according to claim 3 is characterized in that: The step S6 comprises the following steps: S6.1 Sending a fertilizer supplementation instruction or a non-fertilization supplementation instruction through the user interface module, and sending the instruction information to the signal processing module, and the signal processing module sends the signal to the data processing module for processing; S6.2, sending the instruction information to the wireless transmission module through the data processing module for signal transmission, and transmitting the signal to the information collection module; S6.3, the information acquisition module transmits the signal to the automatic replenishment module, and the automatic replenishment module starts or turns off the power supply through the execution switch to realize automatic fertilizer replenishment.

9. The method of a smart agricultural water-fertilizer integrated machine based on intelligent control according to claim 3 is characterized in that: The step S8 comprises the following steps: S8.

1. Turn on the pressure regulating switch through the user interface module and send the information to the signal processing module through the data processing module for digital signal operation and to the information acquisition module. The information acquisition module sends the information to the water pressure regulating module to adjust the water pressure and perform irrigation operations; S8.

2. If the external water pressure is greater than the standard water pressure, the user interface module sends the start information to the information collection module, the information collection module sends the collected information to the low-pressure pump, and the low-pressure pump starts the power supply by executing the switch; if the external water pressure is less than the standard water pressure, the user interface module sends the start information to the information collection module, the information collection module sends the collected information to the high-pressure pump, and the high-pressure pump starts the power supply by executing the switch; S8.

3. If the external water pressure is equal to the standard water pressure, the user interface module sends the start information to the information acquisition module, the information acquisition module sends no signal to the high-pressure pump and the low-pressure pump, and the high-pressure pump and the low-pressure pump turn off the power supply through the execution switch.

10. The method of a smart agricultural water-fertilizer integrated machine based on intelligent control according to claim 3, characterized in that: The step S9 comprises the following steps: S9.1, sending the internal and external information of the soil to the data processing module through the information collection module to process the data of the water-fertilizer integrated machine; S9.

2. The information after data operation is sent to the signal processing module. The signal processing module transmits the signal to the information acquisition module and sends it to the automatic irrigation module. The automatic irrigation module turns on or off the power by executing the switch.
