Big data irrigation control system based on water conservancy channels

Abstract

The invention discloses a big data irrigation control system based on water conservancy channels. The system comprises an irrigation area data collection module, a flow detection module, an irrigationarea data sorting module, a water supply priority pre-screening module, a hierarchical channel opening and closing distribution module, a data analysis platform, a channel opening and closing processing module and a channel opening and closing execution module. The system analyzes the replenishment demand coefficient of irrigation water required by each planting subunit and the water supply priority level contained in each monitoring subarea, sequentially control the irrigation release height of gates between main channels and branch channels and between branch channels and the planting unitsaccording to the water supply priority so that all the planting units at the same water supply priority complete irrigation synchronously, supplies water for all the planting units according to the order of the water supply priority to ensure that crops with urgent water demand are given priority to replenish water, improves the rationality of water supply to each planting subareas and improves the yield of the crops.

Description

technical field [0001] The invention belongs to the technical field of irrigation of water conservancy canals, and relates to a big data irrigation control system based on water conservancy canals. Background technique [0002] Agricultural irrigation refers to the irrigation of agricultural farming areas. During irrigation, water flows into irrigation channels from rivers, reservoirs, etc., and flows into farmland through irrigation channels at all levels. At present, due to the lack of effective control and monitoring of irrigation water, water often occurs Too much or too little water flows into the farmland. If the inflow is too little, it cannot meet the water volume required by the crop growth stage. If the inflow is too much, it will lead to waste of water resources, and even cause crops to die, affecting the production and yield of crops. [0003] In the process of watering in existing agriculture, it is impossible to provide a reasonable amount of water for irrigati...

Problems solved by technology

[0004] The purpose of the present invention is to provide a large data irrigation control system based on water conservancy channels, which solves the problems in the prior art that the amount of irrigation water for each crop in the farmland cannot be reasonably controlled and the irrigation water cannot be controlled according to the emergency degree of water demand of each crop. Issues such as sequential water supply
