Intelligent measurement and control integrated gate

1、Intelligent measurement and control integrated gate Functional Overview:

Intelligent measurement and control integrated gate supports multiple control modes, enabling constant flow control, water level control, opening degree control, and more.

1.  The Intelligent measurement and control integrated gate is a modern agricultural water conservancy facility that automatically adjusts gate openings to control the flow rate and direction of water in irrigation canals. Its application resolves numerous challenges associated with traditional manual gates—such as heavy manual maintenance workloads, inability to operate gates in a timely manner, significant water waste, and difficulties in monitoring and metering. It facilitates the transition of irrigation district operations from traditional experience-based management to digital management and serves as a crucial component of water-saving irrigation projects.

2.  Integrated with terminal equipment such as hydrological instruments and high-definition cameras positioned upstream and downstream of the gate, the Intelligent measurement and control integrated gate exchanges information via IoT communication networks and cloud service platforms. This enables networked control of the equipment through platforms and mobile apps while simultaneously uploading data—including hydrological readings, gate opening levels, power status, video feeds, and on-site images—to the software platform, allowing for real-time remote monitoring of irrigation progress across different plots.

3.  Furthermore, leveraging key data such as upstream and downstream water levels and flow velocities, the cloud service platform employs technical strategies—including constant flow control, water level control, and gate opening control—to automate networked gate operation. This renders irrigation water management more scientific, rational, and reliable, achieving optimal water resource allocation and scheduling while enhancing the management efficiency of the irrigation district.

4.  Additionally, administrators can use the cloud service platform to schedule automatic, timed image capture of field irrigation conditions. They can also utilize remote PTZ (Pan-Tilt-Zoom) controls to adjust viewing angles and zoom in on video feeds to capture detailed on-site imagery. By combining this visual data with historical images, operation logs, and running logs, administrators can continuously verify irrigation effectiveness and optimize preset gate commands. This ultimately enables precise control over irrigation duration for different plots, ensuring both accuracy and efficiency in water usage.

2、Intelligent measurement and control integrated gate Operating Principle:

By integrating terminal equipment—such as hydrological instruments and high-definition cameras deployed upstream and downstream of the sluice—and utilizing IoT communication networks and cloud service platforms for data exchange, the system enables networked device control via platforms and mobile apps. Simultaneously, it uploads data—including hydrological readings, sluice gate opening levels, power supply status, video surveillance feeds, and on-site imagery—to the software platform.

3、Intelligent measurement and control integrated gate Overall Structure:

Intelligent measurement and control integrated gate primarily consists of the following components: main gate support structure (sheet metal), gate control system, manual operating handle, gate panel (sheet metal), gate drive mechanism, solar power supply system, outlet bracket (optional), hydrological monitoring instruments (optional), and a cloud service platform.

4、Intelligent measurement and control integrated gate Power Supply:

1. Supports 12V DC power supply (note: as the screw-drive motor operates exclusively on 12V DC, a wide-voltage power input is not supported);

2. Supports solar power supply; the standard configuration includes a 35W solar panel, a solar charge/discharge controller, and a lead-acid battery (12V 12Ah). Solar power systems with other specifications cannot be directly mounted onto the gate's main support structure, and the installation method must be arranged independently.

5、Intelligent measurement and control integrated gate Average power consumption:

1. Operating power consumption: 20W;

2. Standby power consumption: 1.5W.

6、Intelligent measurement and control integrated gate Operating environment: -20 to 70°C.

7、Intelligent measurement and control integrated gate Communication Interfaces:

1. Supports one 4G wireless communication channel for data exchange with a software platform; this enables networked control via the platform or app while simultaneously uploading real-time status information to the platform.

2. Supports one RS485 uplink communication interface, allowing third-party devices to read the gate's current status and control its opening level using the ModBus-RTU protocol.

3. Supports one RS485 downlink communication interface to read measurement data from upstream and downstream hydrological instruments.

4. Supports one RS485 downlink motor control interface; upon meeting control conditions, it sends commands to the drive motor to control the forward and reverse rotation of the screw mechanism, thereby enabling automated, networked control of the gate's opening and closing.

5. Supports one battery voltage monitoring interface to measure the on-site battery voltage and determine the current power supply status.

6. Supports inputs for two limit sensors to restrict the gate's range of motion.

7. Supports an input for a gate position sensor to determine the current opening level of the gate.

8、Intelligent measurement and control integrated gate Valve Body Support Structure:

1. Intelligent measurement and control integrated gate The valve body support structure utilizes "high-strength, integrally formed sheet metal," offering excellent cost-effectiveness.

2. For the support structure of the gate body, water-stop rubber—with a leakage rate of less than 0.25 L/min per linear meter—is employed as the sealing element along the "internal sides and bottom." This material features good elasticity, strong adaptability to deformation, a tight and reliable seal, and a long service life, ensuring sealing performance is maintained under sustained pressure.

9、Intelligent measurement and control integrated gate Gate Panel Specifications:

1.  Gate Material: The gate panel of the integrated smart control sluice gate is made of high-strength, one-piece formed sheet metal; it is driven by a stainless steel screw rod to move up and down along the guide channels of the main gate support structure.

2.  Gate Dimensions: The standard size is 40 × 40 cm; other specifications can be customized.

3.  Gate Motion Components: These utilize wear-resistant Ultra-High Molecular Weight Polyethylene (UHMWPE) material, which offers exceptional wear resistance and self-lubricating properties. This minimizes wear and friction during frequent opening and closing cycles, reduces noise and energy consumption, and thereby enhances the gate's service life and operational stability.

10、Intelligent measurement and control integrated gate Control Modes:

① Remote Control via Platform/App:

Leveraging key data such as upstream water level, downstream water level, and instantaneous flow rate, the cloud service platform implements automated, networked control of gate opening and operation (opening/closing). Based on technical strategies involving constant flow control, water level control, and gate opening control, this system renders irrigation water management more scientific, rational, and reliable, achieving optimal water resource allocation and enhancing management efficiency within the irrigation area.

Constant Flow Control: Administrators preset parameters for "instantaneous flow rate" and "control duration" via the cloud platform. The gate automatically adjusts its opening to maintain the flow rate at the set value and closes automatically once the control duration elapses.

Water Level Control: Administrators preset parameters for "downstream water level" and "control duration" via the cloud platform. The gate automatically adjusts its opening to maintain the downstream water level at the set value and closes automatically once the control duration elapses.

Gate Opening Control: Administrators preset parameters such as "gate opening" and "control duration" via the cloud platform. The gate automatically adjusts to the set opening value and closes automatically once the control duration elapses.

② Gate Handle Control:

Manual Control: In the event of a power outage or emergency, administrators can operate the gate handle to manually control the gate's lifting and opening level.

③ Remote Control via RS485 Network:

RS485 Network Control: Administrators can read the gate's current status and control the gate opening using the ModBus-RTU protocol.
