Description

Technical Field

[0001] The present invention relates to the field of smart agricultural technology, and in particular to a smart protection system and method applied to an irrigation system. Background Art

[0002] Traditional irrigation protection is: manually check the pipeline in real time at intervals to detect whether the pipeline is leaking and whether the metal parts are rusted. When starting irrigation, it is necessary to manually open the valve and the water pump in turn, make sure that the water valve is opened, then turn on the water pump, start irrigation, and when the irrigation volume is reached, make sure that the water valve is closed, then turn off the water pump and stop irrigation. If the pipeline is corroded and damaged, it will leak, and water will not be effectively irrigated to the farmland. In addition, in terms of remote control, if the water valve is not opened due to a circuit failure, the water pressure in the water pipe is too high, which will not only cause the water pipe to rupture, but also shorten the service life of the water pipe.

[0037] like Figure 1 As shown, the present invention provides an intelligent protection system for an irrigation system, comprising:

[0038] Terminal, used to collect operation data of irrigation device;

[0039] An edge end, connected to the terminal, for transmitting the operation data;

[0040] The cloud end is connected to the edge end, and is used to make pipeline judgments based on the operation data, generate automatic decisions, and determine the final irrigation adjustment decisions after manual verification; wherein, the pipeline judgments include: whether leakage and rust occur, whether the irrigation pressure at each irrigation terminal meets the gap threshold, whether the pressure in the pipeline meets the pressure threshold, whether there are abnormalities in the pressure data and flow data of the pipeline, and whether there are faults in each irrigation facility.

[0041] As a specific implementation method, the above-mentioned system composed of three levels of cloud-edge terminal mainly includes: a data acquisition device, a power supply system device, a communication device and an irrigation device; the power supply system device is used to power the main control board and the connected LORA module; the data acquisition device includes a flow sensor, a pressure sensor and a power meter, etc.; the communication device includes a 4G communication module and a LORA communication module; the irrigation device includes a water pipe, a water valve, a water pump and a water hammer absorber;

[0042] During the irrigation process, flow sensors and pressure sensors are deployed at multiple locations on the pipeline, and power meters are deployed at water valves and water pumps. The data of the irrigation device is obtained through these devices. The data is transmitted to the main control board connected to the LORA module through the LORA module connected to these devices. The data is transmitted to the cloud platform through the 4G module on the main control board. By analyzing the data from these flow meters, the pipeline condition can be judged: (1) whether leakage and rust have occurred; (2) whether there is a large difference in irrigation pressure at each irrigation end; (3) whether the pressure in the pipeline is too high; (4) by comparing with the historical data of pipeline pressure and flow, whether there is any abnormality; (5) logical analysis of the status of each irrigation facility is performed to determine whether there is a fault.

[0043] Among them, (1) the flow rate at the end of the water pipe is compared with the flow rate at the water pump at the beginning of the water pipe. If the flow rate at the end is less than the flow rate at the water pump at the beginning of the water pipe, it indicates that a leak has occurred; (2) by checking whether there is a large difference in irrigation pressure at the ends of each water pipe, if there is a large difference in pressure, the equipment in each place can be kept in the same working state by changing the opening and closing size of the valve, which facilitates precise irrigation; (3) and if the pressure at the valve is abnormal, it is necessary to check whether there is a leak; (4) by comparing with the historical data of pipeline pressure and flow, whether there is any abnormality.

[0044] And the cloud platform will give users an early warning. At this time, the cloud platform can observe the irrigation device status of the farmland in real time. When irrigation adjustment is needed, the cloud platform will issue a command, which will be sent to the main control board. Through the LORA module, the command will be issued to operate the pump and valve to adjust and protect the irrigation facilities. When the irrigation is finished, the pump will be turned off first, and the valve will be closed with an appropriate delay to prevent the occurrence of water hammer.
