Delivery of the micro-special gate monitoring system Zhuhai Phoenix Canal project to achieve multi-dimensional monitoring

As the core control equipment of water conservancy projects, the gate's operating stability directly affects the overall functional performance and safety management level of the project. Recently, the condition monitoring system of the micro-special gate was successfully accepted and officially put into use in the Zhuhai Phoenix Canal Water Conservancy project to provide technical support for the safe and stable operation of the gate equipment of the project.

The Phoenix Drainage Channel is located in Xiangzhou District, Zhuhai City, Guangdong Province. The scope of the drainage channel is located in the main urban area. It is an important interface for the interaction between the urban environment and the water environment. It is an important place for people to live and relax. It is also an important carrier for displaying the image of the city. The comprehensive remediation of flood drainage channels is a key livelihood project in Xiangzhou District. It takes the improvement of the water environment as the core, implements water safety and security, and builds smart water affairs.

The system realizes real-time monitoring around four key dimensions：
First, vibration monitoring, Arrange monitoring equipment according to the gate structure to ensure that the vibration measurement direction is consistent with the vibration direction of the structure, monitor the vibration acceleration value, displacement value, and frequency value of the characteristic parts in real time, analyze the health status of the equipment and give timely warning and alarm；
The second is stress monitoring, Monitor the main beam, side beam, support arm, panel, lug, elevator door frame, support beam and column, base, hanging plate and other force components, analyze the stress in combination with material characteristics, structural parameters, and load conditions, analyze the static stress value and the dynamic stress value, and exceed the standard.Time warning alarm；
Third, operating attitude monitoring, Monitor the trajectory of the centerline of the gate, calculate the distance from the gate body to the side rail, and give early warning when the gap exceeds a specific value or the equipment is in abnormal condition; Fourth, monitor the working condition of key components, monitor key parts such as support hinges and bearings, and give early warning when abnormalities such as lock, non-rotation of the fixed wheel, and wear occur.Call the police.

After the system is put into use, it will effectively warn of the initial hidden dangers and ensure the safety of equipment operation; after replacing the traditional manual inspection mode, the staff can check the operating status of the gate in real time, significantly improving the inspection efficiency; at the same time, unnecessary maintenance operations will be reduced, the service life of the equipment will be extended, and the project operation and maintenance costs will be reduced.
