A Microprocessor Managed Shipboard Tank Level Indicator System

摘要

A solid state, microprocessor managed, tank level indicator (TLI) system for shipboard applications is presented. The system derives tank level information from a capacitance meter whose output is processed by an INTEL 8085 based microcomputer. The system's stored program provides time averaging and interpolation functions which compensate for non uniform tank profiles, as well as roll and pitch movement, of the vessel. The stored program may be installed in programmable read only memory by a stand alone program transfer device (PTD) which was designed to facilitate use of a microprocessor development system, such as the Tektronics 8002A with high level language compiler, as a software design tool, thus extending the capabilities of the system in use at the Naval Postgraduate School. The TLI system may easily be expanded to service the full array of tanks in a typical vessel and to provide a variety of functions not implemented in the prototype. (Author)
