Solution | Weite radial gate online monitoring system

In water conservancy projects, the safe operation of radial gates is of vital importance. However, traditional manual inspections and regular maintenance methods have many disadvantages, such as low efficiency, high safety risks, inability to monitor in real time, and short equipment life, which seriously affect the stable operation of water conservancy facilities. To solve these problems, Weite launched an online monitoring system for radial gates.

Technical principles

1. Technical route selection

The Weite radial gate online monitoring system adopts multi-sensor fusion.

Stress monitoring: Durable surface strain gauges are used in combination with finite element models to analyze static/dynamic stress.

Vibration monitoring: Three-axis accelerometers capture flow-induced vibrations and mechanical vibrations.

Operation posture monitoring: Two-axis inclination sensors calculate gate inclination in real time.

Acoustic emission monitoring: High-sensitivity sensors detect abnormalities such as jamming and wear of support hinge bearings.

Internet of Things and data analysis: Real-time data transmission and cloud storage are achieved through multi-channel data acquisition boxes and on-site workstations; time domain/frequency domain analysis is combined with AI algorithms to predict fault trends.

Standard compliance: Strictly follow industry standards such as NB/T 10859-2021 to ensure monitoring accuracy and system reliability.

1. Comparison with traditional technology

Solution

The Weite radial gate online monitoring system adopts the technical principle of multi-sensor fusion + intelligent analysis, transmits and processes the gate operation data through information, and realizes real-time online monitoring of the static stress, dynamic stress, flow-induced vibration response, operation posture and support hinge bearing wear operation status of the gate main beam and arm structure under the radial gate working condition. When data abnormalities occur, the system automatically identifies and alarms. It ensures the safe operation of equipment around the clock, extends its service life, and reduces operation and maintenance costs.

System composition

It is mainly composed of surface stress sensor, acoustic emission sensor, acceleration vibration sensor, stroke displacement sensor, inclination sensor and multi-channel multi-functional signal acquisition processor, data analysis system host and display.

System advantages

Full life cycle management: from real-time monitoring to predictive maintenance, the service life of equipment is extended by more than 20%.

2. Accurate early warning: thresholds are set based on the NB/T 10859 standard (such as vibration displacement > 0.5mm alarm), and the false alarm rate is <2%.

3. Cost reduction and efficiency improvement: reduce the frequency of manual inspections by 80% and reduce operation and maintenance costs by 30%.

4. High reliability: The sensor protection level is IP68, which can adapt to harsh environments such as underwater, high humidity and low temperature.
