Command and Data System for an Undersea Dredge

Abstract

By the use of commercial equipment whose original purpose was to provide alarm monitoring (fire and burglar) over telephone lines, a command and data system was constructed to control an undersea dredge. The system was designed around the Larse Corporation Data Communicators (trademark), and only a PAM multiplexer and a digital demultiplexer were added to make the system perform. The system requirements were analyzed, and only after the candidate design was agreed upon were the ideas put to paper. The system was designed in modules, with the various components grouped according to their function, to simplify interconnecting and test/checkout. The system has performed well, no component failures have occurred to date, and all data and command functions have worked as expected.
