Embodiment Construction

[0023] This overall scheme of high-efficiency irrigation coupling technology based on TCC (full-channel control system) consists of integrated automatic measurement and control gates, sedimentation tanks, reservoirs, pump rooms, field irrigation canal systems and modified downstream water level sensors. By changing the position of the water level sensor, precise control can be achieved through the following calculations.

[0024] Taking the crossbar above the integrated automatic measurement and control gate closing sensor as the reference elevation of 10m, the relative elevation of the top of the pool is measured to be 8.264m, the relative elevation of the bottom of the pool is 4.614m, and the designed flow rate of the agricultural channel connected to the pool is 0.4m 3 , the canal bottom elevation is 7.364m.

Abstract

The invention provides a high-efficiency irrigation coupling technique device based on TCC (Total Channel Control). The high-efficiency irrigation coupling technique device comprises an integrated automatic measurement and control gate (13), a sedimentation tank (17), a clean water pond (22), a pump house (24), a field irrigation canal system (25) and a changed downstream water level sensor (20). The high-efficiency irrigation coupling technique device is characteristics that an integrated measurement and control gate downstream water level sensor (11) in the structure of the integrated automatic measurement and control gate (13) in the TCC is separated, and is transplanted in the clean water pond (22) at the head part of a demonstration core area through a data line (19), so that the water level of the water pond can be automatically controlled through the gate, the purpose of controlling a field automatic high-efficiency water-saving irrigation system is further achieved, and perfect coupling between the TCC and the field automatic irrigation technique is realized. By means of an accurate metering way and a total channel control characteristic, the utilization rate of agricultural irrigation water is improved.

Description

[0001] 1. Technical field [0002] The technology of the invention belongs to the technical fields of water conservancy and hydropower engineering construction, electronics, communication and automatic control. [0003] 2. Technical Background [0004] In 2012, the Shule River Basin Water Resources Management Bureau of Gansu Province, through the strong support of the Provincial Water Resources Department and Tsinghua University, introduced 9 sets of integrated automatic measurement and control gates and 1 set of omni-channel control system software developed and produced by the University of Melbourne in Australia and Rubiken. . At the beginning of 2014, due to the good operation of this system, Tsinghua University determined the Changma South Main Canal Irrigation Area as a demonstration area for technology promotion and application in the scientific research project of "Water Network Multi-Water Source Real-time Scheduling and Process Control Technology" supported by the nat...
