Abstract
The objective of the work reported herein was to use a systems engineering approach to guide development of integrated
instrumentation/sensor systems (IISS) incorporating communications, interconnections, and signal acquisition. These require
enhanced suitability and effectiveness for diagnostics and health management of aerospace equipment governed by the principles
of Condition-based maintenance (CBM). It is concluded that the systems engineering approach to IISS definition provided clear
benefits in identifying overall system requirements and an architectural framework for categorizing and evaluating alternative
architectures, relative to a bottom up focus on sensor technology blind to system level user needs. CBM IISS imperatives
identified include factors such as tolerance of the bulk of aerospace equipment operational environments, low intrusiveness, rapid
reconfiguration, and affordable life cycle costs. The functional features identified include interrogation of the variety of sensor types
and interfaces common in aerospace equipment applications over multiplexed communication media with flexibility to allow rapid
system reconfiguration to adapt to evolving sensor needs. This implies standardized interfaces at the sensor location (preferably to
open standards), reduced wire/connector pin count in harnesses (or their elimination through use of wireless communications).
