[0002] At present, when a large sprinkler is irrigating, its water supply source is generally a single water source. The water is powered by a water pump, and water flows out from the water supply device and is supplied to the sprinkler through the sprinkler water intake device. Such a single water source device has defects: it is difficult to meet the working needs of a large water demand sprinkler. There is also an existing technology that uses multiple parallel water sources to supply water to multiple parallel sprinklers through a main pipe. When the water volume is allocated, it depends on manual experience and habits to start and stop the water source. Such a device has defects: when multiple sprinklers and multiple water sources work in coordination, it is difficult to coordinate, and there is a deviation between the water demand and the actual water supply of the sprinkler. When the water supply is greater than the water demand, it will cause a waste of water pump electricity; when the water supply is less than the water demand, the sprinkler irrigation effect is poor, which is easy to cause crop yield reduction; when the pipeline is damaged and leaking, it cannot be warned in time, which is easy to cause water waste.

[0008] Compared with the prior art, the multi-source pump valve cluster device of the large sprinkler irrigation machine of the present invention has the following characteristics: 1. By setting up multiple water sources, water supply can be realized nearby, and water supply can be provided according to flow rate and pressure, which can reduce the power loss of the water pump motor; 2. By setting up a water supply single-chip computer system, the water supply pump motor can be controlled to operate at variable frequency through the water supply pump control module, thereby reducing energy consumption while ensuring the expected flow rate and pressure. Coordinated water supply is faster and more accurate. The technical solution adopted by the present invention to solve the technical problem is: a control method of a multi-water source pump valve cluster device for a large sprinkler irrigation machine of the present invention comprises the following steps: ① When the sprinkler is working, the required flow value and pressure value are sent to the server through the 4G / 5G network. After receiving the information, the server matches the corresponding sprinkler water intake device and splits the flow according to the priority and maximum flow value of each corresponding water source water supply device. Then, the split flow value and pressure value are sent to each water source water supply device. At the same time, the server sends an opening instruction to the corresponding sprinkler water intake device; ② After the water supply network module of the water supply controller of the water supply device receives the flow value and pressure value information, it is transmitted to the water supply single-chip computer system. After the water supply single-chip computer system parses the information, it controls the frequency conversion start of the water supply pump through the water supply pump control module. Water enters the main pipeline from the water source through the water supply device and the water supply branch pipe. The water supply water pressure detection module collects the pressure signal of the water supply water pressure transmitter, and the water supply flow detection module collects the flow signal of the water supply flowmeter. The pressure signal and flow signal enter the water supply single-chip computer system and are converted into pressure value and flow value.

After the water intake single chip computer system parses the command, it controls the water intake electric valve to open through the water intake electric valve control module. Water enters the sprinkler irrigation machine from the main pipeline through the sprinkler water intake device and the water intake branch pipe. The water intake water pressure detection module collects the pressure signal of the water intake water pressure transmitter, and the water intake flow detection module collects the flow signal of the water intake flow meter. The pressure signal and flow signal enter the water intake single chip computer system and are converted into pressure value and flow value. The water intake single chip computer system uploads the real-time flow value and pressure value data to the server through the water intake network module; ④The server compares the pressure values ​​and flow values ​​sent by each water source supply device and sprinkler irrigation device. If the cumulative sum of the flow values ​​of the water source supply device is much greater than the flow value of the sprinkler irrigation device, an early warning message is sent to the user APP to indicate that there may be a leak in the pipeline. The server compares the real-time flow value sent by the sprinkler irrigation device and the required flow value sent by the sprinkler. If the error between the real-time flow value and the required flow value exceeds the threshold, the server program reallocates the flow value and sends it to each water source supply device. The user APP can send query instructions to the server to obtain and display the latest status of each water source supply device and sprinkler irrigation device; ⑤When the sprinkler machine finishes working, it will send the zero flow value to the server through the 4G / 5G network. After receiving the zero flow information, the server will send a shutdown command to the corresponding sprinkler water intake device and each water source water supply device; ⑥ After the water supply network module of the water source supply controller of the water source supply device receives the shutdown command, it transmits it to the water supply microcontroller system. After the water supply microcontroller system parses the command, it controls the water supply pump to stop through the water supply pump control module, thereby ending the water supply; after the water intake communication module of the sprinkler water intake controller of the sprinkler water intake device receives the shutdown command, it transmits it to the water intake microcontroller system. After the water intake microcontroller system parses the command, it controls the water intake electric valve to close through the water intake electric valve control module, thereby ending the water intake.

[0009] Compared with the prior art, the control method of the multi-source pump valve cluster device of a large sprinkler irrigation machine of the present invention has the following characteristics: First, by setting a water source supply controller and a sprinkler irrigation water intake controller, the device can monitor the flow and pressure of each water source supply device and sprinkler irrigation water intake device, and reasonably open the nearest water source for sprinkler irrigation according to the flow and pressure requirements of the sprinkler irrigation machine, which can effectively save water resources and energy. Second, by setting a server to connect with the water source supply controller, sprinkler irrigation water intake controller, sprinkler irrigation machine and user APP through the 4G / 5G network, the status of each water source supply device and sprinkler irrigation water intake device can be viewed in real time with the user APP, and early warning information can be received. It solves the problem that large sprinkler irrigation machines have large water demand and are difficult to allocate when multiple water sources are supplied. Priority water supply can be achieved and energy can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

If the difference between the two is large, an early warning message is sent to the user APP 8 to prompt that there may be a leak in the pipeline.

[0019] The control method of the multi-water source pump valve cluster device of a large sprinkler irrigation machine of the present invention comprises the following steps: ① When the sprinkler 6 is working, the required flow value and pressure value are sent to the server 9 through the 4G / 5G network. After receiving the information, the server 9 matches the corresponding sprinkler water intake device 3, and splits the flow according to the priority and maximum flow value of each corresponding water source water supply device 1, and then sends the split flow value and pressure value to each water source water supply device 1. At the same time, the server 9 sends an opening instruction to the corresponding sprinkler water intake device 3; ② After receiving the flow value and pressure value information, the water supply network module 123 of the water source water supply controller 12 of the water source water supply device 1 transmits it to the water supply single chip computer system 121. After parsing the information, the water supply single chip computer system 121 controls the frequency conversion start of the water supply pump 11 through the water supply pump control module 124.

If the cumulative sum of the flow values ​​of the water source supply device 1 is much greater than the flow value of the sprinkler irrigation water intake device 3, an early warning message is sent to the user APP8 to indicate that there may be a leak in the pipeline. The server 9 compares the real-time flow value sent by the sprinkler irrigation water intake device 3 and the required flow value sent by the sprinkler 6. If the error between the real-time flow value and the required flow value exceeds the threshold, the server 9 program reallocates the flow value and sends it to each water source supply device 1.

After the water intake single-chip computer system 321 parses the instruction, it controls the water intake electric valve 31 to close through the water intake electric valve control module 324, thereby ending the water intake.

[0020] When the present invention is in use, the water sources such as rivers, wells, and reservoirs of the present invention supply water to the main pipe 5 through the water source water supply device 1 and the water supply branch pipe 2, and each sprinkler 6 draws water from the main pipe 5 through the sprinkler water intake device 3 and the water intake branch pipe 4. The water source water supply device 1 of all water sources 7 and the sprinkler water intake device 3 of the sprinkler 6 are connected through pipelines to form a water source network; at the same time, a controller is added to the water source water supply device 1 and the sprinkler water intake device 3, which are connected to the server 9 through the 4G / 5G network to form a data network. When taking water, it is centrally allocated by the server 9, and the program automatically calculates and distributes it according to the priority, maximum flow rate and distance of each water source water supply device 1, so as to improve the utilization rate of water resources and reduce energy loss. At the same time, the status of each water source water supply device and sprinkler water intake device can be monitored in real time through the user APP8, and early warning information can be received.

[0021] Since the water source supply device of the device of the present invention supplies water nearby and supplies water according to flow rate and pressure, the power loss of the water pump motor can be reduced; when the flow rate and pressure are abnormal, the user is warned, the pipeline leakage point can be discovered in time, and water resources can be saved; the flow rate and pressure of the sprinkler irrigation water intake device are ensured to be the required values, so that the sprinkler irrigation machine can work under ideal working conditions, ensure the sprinkler irrigation effect, and achieve increased production.

If the accumulated flow value of the water source supply device (1) is much greater than the flow value of the sprinkler irrigation water intake device (3), a warning message is sent to the user APP (8) to indicate that there may be a leak in the pipeline; the server (9) compares the real-time flow value sent by the sprinkler irrigation water intake device (3) and the required flow value sent by the sprinkler irrigation machine (6). If the error between the real-time flow value and the required flow value exceeds a threshold, the server (9) program reallocates the flow value and sends it to each water source supply device (1); the user APP (8) can send a query command to the server (9) to obtain and display the latest status of each water source supply device and sprinkler irrigation water intake device; ⑤ When the sprinkler (6) finishes working, it will send the zero flow value to the server (9) via the 4G / 5G network. After receiving the zero flow information, the server (9) will send a shutdown instruction to the corresponding sprinkler water intake device (3) and each water source water supply device (1); ⑥ After receiving the shutdown command, the water supply network module (123) of the water supply controller (12) of the water supply device (1) transmits the command to the water supply single chip computer system (121). After parsing the command, the water supply single chip computer system (121) controls the water supply pump (11) to stop through the water supply pump control module (124), thereby terminating the water supply. After receiving the shutdown command, the water intake communication module (323) of the sprinkler water intake controller (32) of the sprinkler water intake device (3) transmits the command to the water intake single chip computer system (321). After parsing the command, the water intake single chip computer system (321) controls the water intake electric valve (31) to close through the water intake electric valve control module (324), thereby terminating the water intake.
