Abstract

The invention relates to the field of sonar detection, in particular to a sonar detection device and method for docking between an underwater robot and an underwater working platform. The sonar detection device comprises a guiding system, a receiving system and controlling systems. The guiding system is installed on the periphery of a docking group port of the underwater working platform. The receiving system is installed at the bottom end of the tail of the underwater robot and used for receiving a guiding signal sent by the guiding system. The controlling systems are all installed in a dry chamber of the underwater robot. The receiving system is connected with the controlling systems through cables. Each controlling system comprises a filter and amplifier circuit, a sampling circuit and a control module. The sonar detection device performs real-time detection on relative coordinates between the underwater robot and the underwater working platform and on the angle of the docking group port plane between the bottom surface of the underwater robot and the underwater working platform so as to control the sailing direction and tilted angle of the underwater robot. In this way, docking accuracy is improved by more than 50 percent.

Description

technical field [0001] The invention relates to the field of sonar detection, in particular to a sonar detection device and a detection method for docking an underwater robot with an underwater working platform. Background technique [0002] With the rapid development of ocean development technology, human beings have moved from shallow water activities to deep sea and even seabed. At present, a large number of engineering implementation or scientific research require the establishment of underwater working platforms. At this time, underwater robots have become an important means of transportation underwater. Underwater navigation of underwater robots and the docking with underwater platforms have become important technologies. Base. In addition, for the rescue of wrecked underwater robots, guidance and docking technology is also required. Due to the short wavelength of electromagnetic waves, long-distance transmission in seawater cannot be achieved, because radio radar po...
