Techniques for Interfacing Multiplex Systems.
Abstract
This report describes a study performed to investigate the various types of aircraft multiplex systems now in use and to make recommendations for the design of a standard multiplex interface which will provide a maximum degree of compatibility with both existing and future systems. Data describing the characteristics of a number of aircraft multiplex systems was collected and compiled. Although Air Force aircraft received priority, consideration was also given to other military and commercial aircraft. Considered were the F-16, B-52 OAS, YAH-64, F-18, F-15 and ARINC 575 systems. MIL-STD-1553B was used as a baseline for comparison. The compiled data was analyzed to determine points of incompatibility between these systems and a feasibility study was performed to assess possible techniques to be used in achieving bus compatibility. The Programmable Interface Module (PIM) design philosophy recommended utilizes a distributed three-microprocessor arrangement to achieve the desired interface compatibility. The three-processor concept allows three independent software-controlled events to occur simultaneously, thus providing an extremely high degree of flexibility for existing systems and for future growth.
