Abstract

Diagnostics capability of combat systems shall be compatible with the Army Diagnostic Improvement Program. Present systems are capable of performing health monitoring and health checks using internal embedded resources. They employ standard sensors and data busses that monitor data signals and built-in test (BIT). These devices provide a comprehensive source of data to accomplish an accurate system level diagnostics and fault isolation at line replaceable unit (LRU) level. Prognostics routines provide capability to identify the cause of predicted failure and corrective action to prevent unscheduled maintenance action. Combat system’s health status and prognostic information are displayed to operator, crew, and maintenance personnel. Present systems use common data/information interchange network in accordance with standards defined in the Joint Technical Architecture (JTA) to provide access to vehicle’s health data. The technologies utilized in present systems include embedded diagnostics, combat maintainer, schematic viewer, etc. Implementation of these technologies significantly reduced maintenance hours of combat systems. Health monitoring, diagnostics and prognostics of future systems will utilize federated software and probes approach. Gauges will determine if the system operates within acceptable performance bands by monitoring data provided by the probes. Health monitoring system will use models of missions to make intelligent choices considering tasks criticality.
