[0023] Any feature disclosed in this specification, unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, an automatic fertilizer distribution fertilization system includes three input pipelines 2 for inputting liquid fertilizers, and the feed port of each input pipeline 2 is respectively connected to a fertilizer storage tank 1, and different types of liquid fertilizers are contained in different fertilizer storage tanks 1, that is, the three delivery pipelines respectively transport different liquid fertilizers; specifically, there are three fertilizer storage tanks 1, and the three fertilizer storage tanks 1 are respectively filled with nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer; the discharge ports of all input pipelines 2 are connected to the same output pipeline 4 for outputting liquid fertilizer, and different types of liquid fertilizers enter the same output pipeline 4 for mixing and are output by the output pipeline 4; the input pipeline 2 is provided with a plurality of control ports connected to the control ports. The controller 6 is an executive component and a monitoring component 22; the executive component is used to control whether the corresponding delivery pipe delivers the corresponding type of liquid fertilizer, and the monitoring component 22 is used to monitor the flow rate of the liquid in the corresponding delivery pipe; the controller 6 is also signal-connected to a geological sensor group 7 for monitoring soil geology. The controller 6 controls the amount of liquid fertilizer delivered by the input pipeline 2 according to the geological data obtained by the geological sensor group 7, so as to achieve the application of fertilizers with a specific ratio of nitrogen, phosphorus and potassium according to the geological data, that is, it can achieve the simultaneous application of one or more of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer, effectively solve the problem of single fertilizer type, avoid the fertilizer plant from re-adjusting fertilizer, and improve the fertilization efficiency. On the other hand, according to the flow data obtained by the monitoring component 22, the controller 6 is used to control the executive component, so as to accurately monitor the amount of liquid fertilizer of the corresponding type, improve the accuracy of the amount of liquid fertilizer, and save liquid fertilizer resources.

[0026] In this embodiment, the specific process is as follows:

[0027] After the geological data acquired by the geological sensor group 7 is transmitted to the controller 6, the controller 6 determines the required ratio of nitrogen, phosphorus and potassium in the fertilizer to be applied according to the geological data, and then controls the executive component installed on the input pipeline 2, and uses the monitoring component 22 to obtain the flow rate of the liquid fertilizer in the corresponding input pipeline 2 as a feedback control condition, so as to achieve the application of fertilizers with a specific ratio of nitrogen, phosphorus and potassium according to the geological data, that is, it can achieve the simultaneous application of one or more of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer. For example, the controller 6 determines that the required ratio of nitrogen, phosphorus and potassium in the fertilizer to be applied is 1:2:3 according to the geological data (this ratio is only for the convenience of explaining the working process in this specification, and the specific ratio is determined according to actual needs), then the controller 6 controls the executive component of the input pipeline 2 connected to the fertilizer storage tank 1 containing nitrogen fertilizer to work, and uses the monitoring component 22 on the input pipeline 2 to monitor the flow rate as a feedback control condition, so as to achieve the flow rate ratio of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer in the corresponding input pipeline 2 to be 1:2:3.

[0028] In this embodiment, the monitoring component 22 is a flow meter; of course, other devices capable of monitoring flow may also be used.

[0029] Example 2

[0030] Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0031] Regarding the execution components, the following feasible implementation methods are proposed.

[0032] like Figure 2 As shown, in the first embodiment, the execution component is a fertilizer pump 3, and different output pipelines 4 are provided with different fertilizer pumps 3, and the fertilizer pump 3 is capable of controlling the flow rate of the liquid fertilizer transported in the corresponding input pipeline 2 by controlling its own rotation speed. Specifically, according to the flow data fed back by the monitoring component 22 on the corresponding input pipeline 2 to the controller 6, the controller 6 controls the rotation speed of the peristaltic pump to realize the delivery of the required flow rate of liquid fertilizer in the input pipeline 2.

[0033] In this embodiment, the fertilizer pump 3 can not only control the flow rate, but also provide power for the liquid fertilizer to flow in the corresponding pipeline. A peristaltic pump can be selected. The peristaltic pump has a driver, a pump head and a hose. It is a liquid delivery device that can achieve high-precision control of the flow rate by controlling the driver speed and the pump body at different flow rates.

[0034] like Figure 3As shown, in the second embodiment, the actuator is a regulating valve 21, and different output pipelines 4 are provided with different regulating valves 21, and the regulating valve 21 controls the flow rate of the liquid fertilizer transported in the corresponding input pipeline 2 by its own opening size. Specifically, according to the flow data fed back by the monitoring component 22 on the corresponding input pipeline 2 to the controller 6, the controller 6 controls the opening of the regulating valve 21 to realize the transport of the required flow rate of liquid fertilizer in the input pipeline 2.

[0035] In this embodiment, the power for conveying the liquid fertilizer may be the pressure of the liquid fertilizer in the fertilizer storage tank 1 .

[0036] In the third embodiment, the actuators are a fertilizer pump 3 and a regulating valve 21, and different output pipelines 4 are provided with different regulating valves 21; different output pipelines 4 are provided with different fertilizer pumps 3; in this embodiment, the regulating valve 21 controls the flow rate, as in the second embodiment; the function of the fertilizer pump 3 is mainly to provide power for the liquid fertilizer to flow in the corresponding input pipeline 2.

[0037] In this embodiment, if a certain liquid fertilizer is not needed, the input of the liquid fertilizer can be avoided by completely closing the regulating valve 21 on the corresponding input pipeline 2 or / and stopping the fertilizer pump 3.

[0038] like Figure 1 As shown, in the fourth embodiment, the actuators are a fertilizer pump 3 and a regulating valve 21, different output pipelines 4 are provided with different regulating valves 21, and all output pipelines 4 are connected to the output pipeline 4 through the same fertilizer pump 3; the main difference between this embodiment and the third embodiment is that the fertilizer pump 3 provides power for the flow of liquid fertilizer in all input pipelines 2.

[0039] Example 3

[0040] Based on any one of the implementations in Examples 1-2, a specific implementation method that can be implemented is further proposed.

[0041] Regarding the geological sensor group 7, this embodiment proposes the following feasible implementation methods.

[0042] In the first embodiment, the geological sensor group 7 is composed of a soil temperature and humidity sensor, a pH sensor, and a nitrogen, phosphorus and potassium sensor. The soil temperature and humidity sensor obtains the temperature and humidity of the soil; the pH sensor obtains the pH of the soil; and the nitrogen, phosphorus and potassium sensor obtains the ratio data of nitrogen, phosphorus and potassium in the monitored soil.

[0043] In the second embodiment, the geological sensor group 7 is an integrated sensor with the function of obtaining soil temperature and humidity, pH, and nitrogen, phosphorus and potassium ratio data, such as a six-in-one sensor model VMS-6001-TR, which can communicate with the controller 6 using RS485.

[0044] Example 4

[0045] Based on any one of the implementations in Examples 1-3, a specific implementation method that can be implemented is further proposed.

[0046] In a feasible implementation manner, a check valve 41 is provided on the output pipeline 4. The check valve is a one-way valve to prevent the liquid (liquid fertilizer or clean water) from flowing back, and effectively prevent the fertilizer pump 3 from stopping suddenly and causing siphoning.

[0047] A feasible implementation manner, the input pipeline 2 is also connected to a clean water pipeline 5, and the connection position between the output end of the clean water pipeline 5 and the input pipeline 2 is located upstream of the actuator; the clean water pipeline 5 provides clean water for the input pipeline 2 and the output pipeline 4, mainly for the output pipeline 4; the clean water replaces the liquid fertilizer in the input pipeline 2 and the output pipeline 4, thereby effectively avoiding the crystallization of the liquid fertilizer in the input pipeline 2 and the output pipeline 4, effectively preventing blockage, and ensuring that the liquid fertilizer can be normally transported next time.

[0048] It should be noted that the connection position between the output end of the clean water pipeline 5 and the input pipeline 2 is located upstream of the actuator, so that the liquid fertilizer in the actuator, especially the pump component, can be replaced by clean water.

[0049] A feasible implementation method is as follows: Figure 1 , Figure 2 As shown, a clean water pump 53 is provided on the clean water pipeline 5 , and the clean water pump 53 provides power for the clean water to flow in the clean water pipeline 5 .

[0050] A feasible implementation method is as follows: Figure 3 As shown, the clean water pipeline 5 is not provided with a clean water pump 53 , and the fertilizer pump 3 can be used to provide power for the clean water to flow in the clean water pipeline 5 .

[0051] A feasible implementation method is that the clean water pump 53 is electrically connected to the controller 6, and the controller 6 controls the working state of the clean water pump 53; the controller 6 controls the opening and closing of the clean water pump 53 and monitors whether the clean water pump 53 fails, thereby controlling whether there is clean water flowing in the clean water pipeline and the delivery pipeline.

[0052] A feasible implementation method is that a solenoid valve 51 is also provided on the clean water pipeline 5, and the solenoid valve 51 controls whether clean water flows in the clean water pipeline 5; the solenoid valve 51 is connected to the controller 6 by wired or wireless means, and the controller 6 controls the opening and closing of the solenoid valve 51 and monitors whether the solenoid valve 51 fails, thereby controlling whether clean water flows in the clean water pipeline and the delivery pipeline.

[0053] In a feasible implementation manner, a pressure transmitter 52 is also provided on the clean water pipeline 5. The pressure transmitter 52 is installed between the solenoid valve 51 and the water inlet of the clean water pipeline 5. The pressure transmitter 52 obtains the flow pressure of the clean water to monitor whether there is water pressure.

[0054] It should be noted that the pressure transmitter 52 is connected to the controller 6 by wire or wireless means, and the pressure transmitter 52 transmits the acquired pressure data to the controller 6, and the controller 6 acquires the actual pressure data and determines whether the actual pressure data is greater than the set pressure data. When the acquired actual pressure data is greater than the set pressure data, the entire system can start to work normally; to ensure that when the fertilizer pump 3 fails and stops suddenly during the transportation of liquid fertilizer, there is sufficient water pressure to transport clean water to the output pipe and the input pipe to replace the liquid fertilizer in the transportation pipe.

[0055] A feasible implementation manner is that the controller 6 has a display screen 61 for displaying data; the display screen 61 displays the flow data and pressure data acquired by the monitoring component 22 and the pressure transmitter 52 in real time, and displays the real-time status of the execution component (open, closed or fault status).

[0056] A feasible implementation method is that the controller 6 is provided with an alarm, and the controller 6 controls the executive component, the solenoid valve 51, and the clean water pump 53 and monitors them, so that the executive component, the solenoid valve 51, and the clean water pump 53 can be detected in time when they fail, thereby reducing manual inspections, reducing labor costs, improving inspection efficiency, and avoiding system failures; the monitoring component 22 and the pressure transmitter 52 can monitor the amount of fertilizer and water applied, improve the accuracy of water and fertilizer usage, and save water and fertilizer resources.

[0057] Specifically, when an executive component fails, the controller 6 will emergency stop and alarm to remind the patrol personnel to inspect and repair; when the liquid fertilizer delivery volume monitored by the monitoring component 22 reaches the set value, the controller 6 will receive the relevant signal of the monitoring component 22, thereby controlling the relevant components to stop working, so as to improve the accuracy of liquid fertilizer usage and save liquid fertilizer resources.
