A remote monitoring system and monitoring method for the health status of a ship lock

Abstract

The invention discloses a ship lock health state remote monitoring system and a monitoring method thereof. The monitoring system comprises an optical fiber crack detection subsystem, an optical fiber grating strain detection subsystem, a vibration detection subsystem, a lock chamber water level measurement subsystem, an environmental parameter detection subsystem, an AIS base station, an optical fiber demodulation module, a data acquisition computer, a remote transmission terminal, a cloud side database and a command center monitoring room. The onsite non-destructive optical fiber sensing technology is utilized, information including strain and temperature of all the monitoring positions of a mite lock gate and the overall three-dimensional movement state of the mite lock gate can be rapidly acquired in real time, and the structural deformation, the structural dynamic characteristics and the health operation state of the mite lock gate can be accurately judged by using multiple algorithms and prior knowledge through data analysis and processing and expert systems so that the objective of monitoring the structural damage or deterioration of the system in real time can be achieved, and safe, efficient, stable and reliable operation of the ship lock can be powerfully guaranteed.

Description

technical field [0001] The invention relates to the technical field of health monitoring of hydraulic metal structures, in particular to a monitoring system for the health status of ship locks. Background technique [0002] The miter gate of the ship lock works under the condition of low speed and heavy load for a long time. With the increase of the gate opening and closing times, the contact surfaces of the top pivot, bottom pivot, connecting door shaft and other moving parts will gradually appear poor lubrication. In addition, during the operation of the miter door, it will be affected by surge waves, dynamic water loads, the operating state of the hoist and the huge water pressure on both sides of the underwater door body, which will cause frequent vibrations of the door body and small up and down displacements of the door body. beat. When the excitation frequency is close to the natural frequency of the miter door, it will cause the door body to resonate, resulting in s...

Problems solved by technology

[0003] In order to ensure the safety of the ship lock structure, the current monitoring of the health status of the ship lock is still carried out by manual inspection and six-year cycle overhaul, which not only affects the channel transportation, but more importantly, manual inspection cannot achieve real-time monitoring, and there is a possibility of missing inspections , there is a great security risk
