UUV battery pack intelligent cascade expansion architecture and cascade expansion method

Abstract

The invention provides a UUV battery pack intelligent cascade expansion architecture and a cascade expansion method, and solves problems that the existing battery pack cascade operation prerequisite condition requirement is high, the operation process is complex, the safety is poor, the expansion use form is single, and the UUV battery pack intelligent cascade expansion architecture and the cascade expansion method are not suitable for flexible configuration of multiple sets of battery packs. By means of bus type communication, automatic ID distribution, automatic differential pressure detection and electric quantity balance, series-parallel independent switching and the like, safe and intelligent cascade expansion of multiple groups of batteries can be realized. According to the invention, a star topology structure is adopted, the control method is simple, the architecture has control instruction code table generation specifications capable of adapting to any number of expansion nodes, the number of theoretical expansion nodes can reach 128, fault diagnosis and fault isolation of the battery pack of any node are convenient, the expansion forms are various, and the use safety and the expansion flexibility of the UUV battery pack can be fully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of UUV battery control, and in particular relates to an intelligent cascade expansion architecture and a cascade expansion method of a UUV battery pack. Background technique [0002] In recent years, unmanned underwater equipment with UUV (unmanned low-speed underwater vehicle) as the main body has gradually emerged in military and civilian underwater applications; UUV is an intelligent equipment that can move autonomously underwater for a long time. It can carry a variety of detectors, sensors and other equipment loads to perform underwater tasks. For example, applications in the civilian field include underwater exploration, underwater salvage, emergency rescue, scientific investigation, underwater archaeology, auxiliary operations, pipeline laying, etc. As the diversity of UUV tasks becomes more and more complex, the uncertainty of its underwater working time and carrying loads is increasing, and then the...
