Problems solved by technology
In many areas of our country, due to the water resources management model of flood irrigation and supply and demand, the utilization efficiency of agricultural water resources is lower than 50%, which seriously threatens the local life and ecological water resources utilization.
Moreover, in many areas, the ecological water consumption is squeezed out by the agricultural water consumption, resulting in the deterioration of the ecological system.

The invention relates to an intelligent distribution control system for agricultural water resources, which is characterized in that during the growth of crops, the meteorological element data collector collects the signal obtained by the meteorological element sensor, and transmits it to an analog-to-digital converter to generate a digital signal, and through the data micro After the processor organizes and encodes it, it uses the signal transmission system to transmit it to the surface-groundwater joint intelligent distribution system; after the system calculates the received data through the model, it intelligently and automatically , Scientifically assigned to the water unit. Control the diversion amount and diversion time of surface and groundwater, so as to activate the surface water flow controller and groundwater flow controller to achieve the purpose of precise joint scheduling of surface water and groundwater, thus effectively improving the efficiency of agricultural water use under the premise of ensuring the rational allocation of water.
Description
technical field [0001] The invention belongs to an intelligent distribution control system of agricultural water resources, specifically refers to a system capable of realizing the intelligent distribution of agricultural water resources under different climatic conditions and soil conditions according to meteorological observation, soil moisture status, crop growth period and irrigation canal system parameters Control System. Background technique [0002] About 70% of the world's freshwater resources are used for agriculture, and the rational management and allocation of agricultural water resources affect global, national and regional water security and food security. In many areas of our country, due to the water resource management model of flood irrigation and supply and demand, the utilization efficiency of agricultural water resources is lower than 50%, which seriously threatens the local life and the utilization of ecological water resources. Moreover, in many areas...
