Abstract

The invention discloses a photovoltaic water lifting balanced irrigation intelligent control system. The system comprises a controller, a voltage converter is connected with the input end of the controller, and an electricity storage device is connected with the input end of the voltage converter; a photovoltaic generating device is connected with the input end of the electricity storage device, an irrigation control device is connected with the output end of the controller, a soil humidity detection system, a remote control terminal and a water volume monitoring system are in double-way connection with the controller, and a storage module is connected with the output end of the remote control terminal. The system can store energy which is collected by the photovoltaic generating device, meanwhile scientifically adjusts the number of irrigation units, optimizes configuration, irrigation and water supplying, solves the problem of uneven irrigation due to discontinuous water lifting which is caused by discontinuous photovoltaic generating for a long time, and can detect the soil humidity of irrigation areas anytime, remarkably improve the irrigation evenness of the irrigation areas,improve the use ratio of energy and resources and reduce labor cost and engineering input cost. The photovoltaic water lifting balanced irrigation intelligent control system can be widely applied to project engineering which adopts photovoltaic water lifting for irrigation.

Description

technical field [0001] The invention relates to the technical field of irrigation, in particular to an intelligent management and control system for balanced irrigation with photovoltaic water lifting. Background technique [0002] Technical measures for replenishing the field with the water needed for crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient and uniform water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. [0003] Irrigation, i.e. irrigating the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of the planted plants, the growth stage, climate, and soil conditio...
