Remote automatically-controlled water saving system for gates in irrigation district

Abstract

The invention discloses a remote automatically-controlled water saving system for gates in an irrigation district, and belongs to the technical field of modern and automatic management in irrigation districts. The remote automatically-controlled water saving system comprises a monitoring centre, a gate in-situ control unit, a canal system, the gates and water measuring flumes, wherein the monitoring centre comprises a main controller and a display unit, and the main controller comprises a water level flow monitoring unit, a fault analysis unit, a storage unit, an alarm and an optimized water distribution unit; the gate in-situ control unit comprises a programmable controller, a gate opening-closing transmission mechanism, and water level sensors, the canal system comprises two or more canals, and one gate is arranged at a water inlet of each canal; and one water measuring flume is arranged in each canal, and a water level measuring well provided with one water level sensor is arranged at each canal bank. According to the remote automatically-controlled water saving system disclosed by the invention, the problem of low modern and automatic level of management in irrigation districts at present is comprehensively solved, and the utilization rate of irrigation water is increased, thus valuable water resources are saved, a pivotal role is played on the sustainable development of the irrigation district, and increase for an agricultural modernization degree is benefited.

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
