Description

Technical Field

[0001] The present invention relates to the technical field of agricultural irrigation equipment, and in particular to a water metering method and system based on a hydropower fusion terminal. Background Art

[0002] In modern agricultural irrigation systems, accurate water measurement is essential to improve irrigation efficiency, save water resources, and achieve sustainable agricultural development. However, traditional water measurement methods often rely on mechanical water meters or simple electronic flow meters, which often have difficulty ensuring measurement accuracy in the face of complex irrigation environments, such as power stability issues and water level changes.

[0003] Fluctuations in the power supply voltage will directly affect the efficiency of the water pump, thereby changing the amount of water corresponding to the unit power consumption. In the case of unstable power, the traditional water metering method cannot adjust the power-to-water coefficient in real time, resulting in deviations in the metering results. The drop in the water level of a well or reservoir affects the water absorption capacity and working efficiency of the water pump. Under different water level conditions, the amount of water pumped for the same power consumption may be different, resulting in inaccurate metering results. Summary of the invention
