Patent number: 11977201Abstract: The invention discloses an integrated detection method of electromagnetic searching, locating and tracking for subsea cables. After being launched into water, the cable-tracking AUV carries out primary Z-shaped reciprocating sailing to search the electromagnetic signal of the target subsea cable, when the electromagnetic signal reaches a preset threshold value, the AUV executes the cable-tracking detection. In the tracking process, if the target electromagnetic signal intensity is lower than the preset threshold, it is determined that subsea cable tracking is lost. At this time, the secondary Z-shaped cable-researching route planning and tracking are performed based on the lost point. In the process that the AUV autonomously tracks and detects the subsea cable, relative locating between AUV and subsea cable is performed based on the electromagnetic signal radiated by the subsea cable, and autonomous tracking control under the guidance of the electromagnetic locating signal is performed.Type: GrantFiled: June 10, 2022Date of Patent: May 7, 2024Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Xianbo Xiang, Jialei Zhang, Shaolong Yang, Qin Zhang, Gong Xiang, Guohua Xu
