At present, the operation and maintenance of the ship lock still uses manual stationing, manual inspection, experience judgment and other methods to carry out on-site maintenance and hidden danger inspection of the ship lock, or use conventional information systems to monitor the status of the ship lock. Some safety hazards are not easy to detect through manual inspections, and the effectiveness is poor. It is easy to miss detection and false detection, which leads to the inability to accurately monitor the hydraulic structure, equipment and facilities of the ship lock, and the opening status of the ship lock.
