[0069] The central processing unit 1 receives data acquired by the soil moisture acquisition module 14, which uses a soil moisture meter to acquire soil moisture data for the corresponding area.

[0070] Example 4:

[0071] As another technical solution, a water pump control method for an automatic irrigation system is provided, which is used in conjunction with the aforementioned automatic irrigation system, and includes the following steps:

[0072] S1: Data acquisition: Data is acquired through weather data acquisition module 16, environmental data monitoring module 15 and soil moisture acquisition module 14 and transmitted to the central processing unit. The central processing unit 1 identifies the data and determines whether irrigation is needed based on the weather data.

[0073] A: When irrigation is needed, the soil moisture data is transmitted to the data analysis module 11 for data analysis of soil moisture content data, and then transmitted to the data comparison module 12. The data is compared with the soil moisture data required for this growth stage in the crop breeding data storage module 13 to obtain the required irrigation water amount. The required irrigation water amount is then transmitted to the central processing unit 1, and the central processing unit 1 controls the irrigation equipment 2 to start irrigation.

[0074] B: When watering is not required, the central processing unit does not perform any processing;

[0075] Irrigation is not carried out when the weather is rainy, but it is started when the weather is sunny, cloudy, or overcast. The amount of water delivered is strictly controlled during irrigation.

[0076] S2: The irrigation equipment is started. The irrigation equipment 2 acquires irrigation data, controls the drive motor 21 to start, and controls the pressurization and depressurization frequency of the pressure pump 36 according to the data of the central processor 1. At the same time, the rotation of the rotating table 42 is started to effectively filter impurities in the water flow and prevent the spray nozzles from being blocked.

[0077] In the above method, the filter rotates during startup, effectively filtering impurities in the water.

[0078] Working principle: Data is acquired through the weather data acquisition module 16, the environmental data monitoring module 15, and the soil moisture acquisition module 14 and transmitted to the central processing unit. The central processing unit 16 identifies the data and determines whether irrigation is needed based on the weather data. If irrigation is needed, it compares the required amount of aquaculture water and then controls the pump of the irrigation equipment to start and controls the pressure during irrigation, so that the watering covers the area evenly. This avoids the situation in the prior art where the output power of the water pump needs to be controlled, which would reduce the life of the water pump.
