Distributed multiplexers for an ROV control and data system
E. Mellinger, A. Pearce, M. Chaffey · 2002
Remotely operated vehicle (ROV) control and data systems require that many specialized input/output (I/O) functions be reliably performed in the hostile ocean environment. MBARI's new scientific ROV Tiburon uses a system of I/O multiplexers that are distributed around the vehicle, and connected to the main vehicle computer by high-speed serial links. The multiplexers perform fairly typical ROV I/O functions, but their hardware, software, and packaging has been specifically optimized for the ROV mission. This paper describes the design and application of these multiplexers, dubbed "Data concentrators", aboard MBARI's new vehicle.>
