Data acquisition method and system for visual management of underwater pressure-resistant battery pack

Abstract

The application provides a data acquisition method and system for visual management of an underwater pressure-resistant battery pack, and relates to the technical field of battery management.The method comprises the following steps: step 1, a remotely operated vehicle is dived to the position of a pressure-resistant cabin of a battery pack, and a wet-plug electrical connector is positioned; a real-time image of the wet-plug electrical connector is acquired by a visual recognition component of the remotely operated vehicle, and the blockage state of a connector interface is identified according to the real-time image; step 2, a cleaning device of the remotely operated vehicle is controlled to clean the connector interface by high-pressure water jet, and a cleaned connector interface is obtained; a cleaned image is acquired by the visual recognition component, and a plurality of spatial coordinate points on the surface of the connector interface are extracted from the cleaned image.The reliable connection of the connector is achieved by positioning and cleaning, deformation evaluation and compensation docking, the complete acquisition of historical operation data of the battery pack is ensured, the historical operation data is transmitted to a shore base, and precise data support is provided for the visual diagnosis and evaluation of the health state of the underwater pressure-resistant battery pack.
