Construction Goals
The integrated monitoring and control gate system design encompasses multiple aspects. It includes not only the construction of the gates at the field end but also the uploading of gate information, flow meter measurement data, and video image information to the platform via network layer and BeiDou communication. The platform collects, analyzes, and processes irrigation area data, facilitating comprehensive management of multiple points and water dispatching, truly achieving intelligent water allocation in the irrigation area.
The biggest change brought about by the information technology construction of the integrated monitoring and control gate system is “unmanned operation.” The system can automatically collect measurement data from external sensor devices and intelligently control the gate opening based on built-in control logic to achieve automatic control of water level and flow. The system can wirelessly transmit local status, sensor measurement data, and gate status video data to a remote server. Combined with the company’s supporting mobile APP and WEB platform, it enables real-time monitoring of the gate control system, achieving unmanned operation.
System Architecture
The integrated measurement and control gate system refers to a hardware and software system that highly integrates measurement and control functions, utilizing various advanced technologies to achieve real-time monitoring and precise control of gate-related parameters. This system features remote control, video monitoring, anomaly alarms, voice broadcasting, and multiple automatic control modes, avoiding water waste in traditional irrigation and providing strong technical support for the modernization of agriculture. It mainly consists of five parts: the integrated measurement and control gate, water measurement facilities, video monitoring, communication network, and software platform.
