Smart Irrigation District Supervision System

The smart irrigation area information platform uses advanced technologies such as the Internet of Things, the Internet, cloud computing, and big data analysis to obtain real-time and accurate information on water and rainfall conditions, soil moisture conditions, channel water levels, channel flow, pump station operating status, gate operating status, on-site video, and other information. It processes the collected data to achieve real-time sharing of information resources in the irrigation area, improve the operational efficiency of the irrigation area, and reduce operational costs. It provides scientific decision-making basis for the irrigation area management department, ultimately achieving informatization of irrigation area management, rational allocation of water, precise measurement of water, automation of control, and standardization of charging, providing technical support for efficient modern agriculture.

Project Overview: The comprehensive reform project of agricultural water prices in the Zhoujia irrigation area of Zhaoping County is located in the Zhoujia irrigation area of Zhaoping County, Guangxi. The irrigation area was originally designed to irrigate 14,000 acres, with an effective irrigation area of 9,500 acres. Due to the requisition of part of the irrigation area of the North Canal, the planned irrigation area for this implementation scheme is 11,300 acres, including 9,040 acres of rice, 1,469 acres of citrus, and 790 acres of other crops. It involves villages such as Huangyao Street Village, Bengjiang Village, Gongqiao Village, Bitou Village, Jianpan Village, Zhongdong Village, Xinzai Village, Baishan Village, Chunfu Village in Huangyao Town, and Jiatian Village in Zhangmulian Township.

The work mainly involves: the construction of 49 new gate control points, 3 sets of precise integrated gates, 16 sets of conventional integrated gates, 30 sets of manual gates, 91 sets of water measurement facilities, 4 Doppler monitoring points, 46 rectangular weir monitoring points, and 41 standard cross-sections + water level gauge monitoring points. One centralized control center.
