In modern water conservancy engineering and smart water construction，Gate remote control systemIt has become the core technology for achieving accurate dispatching of water resources, flood prevention and disaster reduction, and unattended. Whether it is a reservoir and dam with extremely high flood control safety requirements, a channel in an irrigation area with a huge spatial span, or a pumping station related to the safety of urban and farmland drainage, a set of efficient and stableGate remote control systemThrough the Internet of Things, automation control and big data technology, they can transform the heavy work that originally required manual on-site operation into “one-click scheduling” in the monitoring center or mobile app.
1. The core composition structure of the gate remote control system
A complete set ofGate remote control systemIt is usually constructed vertically from the four levels of perception, control, transmission, and application.
At the perception layer, the system relies on high-precision radar water level meters, ultrasonic flow meters and gate opening sensors to capture water level changes and the physical location of the gate in real time and accurately, and cooperates with high-definition video surveillance to achieve intuitive visualization of the live screen. The control layer is the “brain” of the system, usually using an industrial-grade programmable logic controller (PLC) as the core of local control to receive and execute instructions. The transport layer uses industrial-grade 5G/4G wireless networks, optical fiber ring networks or Beidou satellite links to ensure that massive amounts of data can be uploaded stably in bad weather. In the end, all data is aggregated into a smart water integrated management platform at the application layer, providing managers with large-screen monitoring and remote operation interfaces.
2. Customized automatic control logic for different water conservancy scenarios
For different scenarios such as reservoirs, channels, and drainage pumping stations，Gate remote control systemDifferentiated customized automatic control logic needs to be written to meet complex business needs：
1. Reservoir gate remote control system: safety flood prevention and porous linkage
Reservoir safety is related to the lives and property of millions of people downstream, and its control logic emphasizes safety and accuracy. The customized system supports the ”group gate linkage" algorithm. When faced with the demand for flood spillage, the system can automatically calculate and evenly distribute the opening of each hole gate according to the target total flood spillage volume, so as to avoid excessive single-hole flow rate and scour the downstream riverbed. At the same time, the system has a built-in water level-opening closed-loop PID algorithm, which dynamically fine-tunes the gate according to the rising rate of the reservoir water level to prevent man-made flooding caused by excessive opening of the gate. In the event of extreme danger or power failure, the system also has a safety guarantee mechanism for the backup power supply to be forcibly turned on or off.
2. Channel gate remote control system: integrated measurement and control and precise water distribution
Long-distance channels and irrigation areas rely more on precise flow control. Traditional control methods are difficult to cope with fluctuations in upstream water, while advanced channelsGate remote control systemThe “integration of measurement and control” has been realized. The system uses standard hydraulic formulas to calculate the flow of water in real time based on the water level before and after the gate and the opening of the gate. When the incoming water fluctuates, the gate will automatically fine-tune the opening based on customized logic to ensure that the flow to the downstream is always constant. In addition, for multi-level channels, the system supports upstream and downstream cascade control, and the downstream water demand changes can be transmitted to the gates at all levels in a directional manner, and linkage adjustments can be made in advance, effectively eliminating the phenomenon of channel overflow or drying up.
3. Remote control system of drainage pumping station: interlock of pump gates and flood prevention and drainage
The drainage pumping station involves the synergy between the gate and the water pump, and its control logic focuses on “anti-reverse irrigation” and “equipment protection”. Customized control logic strictly implements the pump gate interlock mechanism, and only when specific water level conditions and gate opening and closing sequence are met, the equipment is allowed to start. For example, when the level of the outer river is higher than that of the inner river, the system automatically closes the gate to prevent reverse irrigation, and automatically turns on the drainage pump for strong drainage. In a pumping station with multiple water pumps operating, the system can also automatically determine the number of water pumps to be started according to the water level classification of the catchment pool, and implement a rotating start-stop logic to balance the operating wear time of each water pump, thereby extending the service life of the entire equipment.
3. The smart water affairs platform realizes one-network management
modernGate remote control systemIt is no longer an isolated single-point control, but integrates all nodes such as reservoirs, channels, and pumping stations into a single map of smart water affairs. Through the digital twin or GIS geographic information system, managers can fully grasp the operation dynamics of all water conservancy facilities in the watershed.
The system provides multi-level authority management to ensure that the Flood prevention Office, Reservoir Management Office and Channel Management Office perform their respective functions. Remote control instructions need to pass strict security verification, and the whole process automatically generates video recordings and log audits to ensure operation safety and compliance. When the water level exceeds the limit, equipment failure or illegal intrusion is encountered, the system will trigger intelligent early warning through SMS, APP push, etc. as soon as possible to assist managers in turning passive response into active prevention.
By deploying customized logic in reservoirs, channels and drainage pumping stationsGate remote control system, The water conservancy management department can not only greatly improve the efficiency of the utilization of water resources, but also realize scientific, efficient and safe refined flood prevention and control during the main flood season, and provide a solid scientific and technological support for modern water conservancy construction.
