Water-saving system for remote automatic control of gates in irrigation districts

Abstract

The gate remote automatic control water-saving system of the irrigation area belongs to the field of modernization and automation management technology of the irrigation area, including the monitoring center, the gate local control unit, the canal system, the gate and the water measuring tank; the monitoring center includes the main controller and the display unit, and the main controller includes Water level and flow monitoring unit, fault analysis unit, storage unit, alarm and optimized water distribution unit; gate local control unit includes programmable controller, gate opening and closing transmission mechanism, water level sensor, and the canal system includes two channels or more than two channels, and the water inlet of each channel is provided with a gate; the inside of the channel is provided with a measuring tank, and the embankment of the channel is provided with a water level logging device equipped with a water level sensor. The invention comprehensively solves the problems of modern management and low level of automation in current irrigation areas, improves the utilization rate of irrigation water, saves precious water resources, plays a key role in the sustainable development of irrigation areas, and contributes to the improvement of agricultural modernization.

Description

technical field [0001] The invention belongs to the technical field of automatic management of irrigation districts, and in particular relates to a water-saving system for remote automatic control of gates in irrigation districts. Background technique [0002] The agricultural water-saving measures used by countries all over the world can be summarized into four categories: engineering water-saving, agronomic water-saving, biological water-saving and management water-saving. The application of these water-saving measures is roughly distributed in four basic links: one is to reduce water evaporation and seepage loss in the process of canal pipeline water delivery, and improve the efficiency of irrigation water delivery; the other is to reduce the loss of water in the process of field irrigation. Deep seepage and surface loss can improve the utilization rate of irrigation water and reduce the water consumption per unit of irrigated area; the third is to store water and preserv...

Problems solved by technology

Sun Jian from the Hongjin Irrigation District Management Office in Huai'an City, Jiangsu Province published the development and application of the automation control system of the Hongjin Irrigation District. Although the detection and control gates are proposed, there are no water measurement facilities, and the accuracy of control and flow measurement cannot be achieved; Wuhan Wu Jing of the University of Science and Technology published the design of the remote control system for the gate of the irrigation area, although the database was established, but it was unable to automatically control the open channels and pipelines; Liu Shubo, Xu Zhanguo, etc. Realize the remote automatic control of the gate, but it is impossible to realize the real-time control of the gate according to the flow change
