Existing approaches to accomplishing fault tolerance typically focus on \"brute-force\" hardware redundancy and extensive, complex control logic developed as a \"point solution\" to effect reconfiguration actions. This paper describes the principal concepts and design implementation of an innovative approach for embedding an adaptive model-based diagnostic reasoning capability into a Fault Tolerant Remote Power Controller (FTRPC) to provide rapid fault diagnostics and reconfiguration of powerflow to critical users. A key aspect of this approach is that a systems engineering process was used to develop the reasoning capability that could be embedded in the system to accomplish fault detection, isolation, reconfiguration and recovery. The system engineering process, applied through an automated tool set, is generic in nature and can be applied to any system, as opposed to a \"point solution\" developed by intensive engineering efforts. The extensibility and applicability of the overall approach is a key technology accomplishment of the program. This paper describes the underlying concepts and implementation of embedding Diagnostician-on-a-Chip technology into a state-of-the-art remote power controller. This design was recently implemented in an Integrated Product Development environment under a NASA Phase II SBIR Program conducted under the auspices of Marshall Space Flight Center (MSFC). This new approach can revolutionize the implementation of health management for fault tolerant systems by developing a deterministic model-based diagnostic capability that is adaptive to a vast number of dynamic reconfiguration states.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

Re-engineering legacy tech manual's troubleshooting procedures into smart model-based diagnostics 将遗留技术手册的故障排除过程重新设计为基于智能模型的诊断

These flow charts guide the technician through test procedures to isolate the cause of an equipment malfunction. These procedures are static, that is they are highly structured around a pre-determined sequence of tests, do not become \"smarter\" over time with historical maintenance data and they only take into account those symptoms and faults which the original developer considered. They are often incomplete, sometimes wrong, and are very difficult to update and maintain. As the Army moves to computer-assisted methods of maintenance, the opportunity exists to significantly enhance the basic logic and knowledge representation underlying troubleshooting procedures. The enhancements include knowledge based reasoning about faults related to symptoms, the ability to dynamically relate faults to symptoms, the ability to use historical maintenance data to continuously improve maintenance capability, and the ability to house \"expert\" diagnostics information in a form that becomes usable and available to novice technicians. However, can tree-based troubleshooting logic from legacy systems be efficiently re-engineered to a knowledge-based system with the same benefits? This paper addresses the aspects of transitioning from flow-chart intensive knowledge representation to a format which provides the benefits described above.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

Testing at the BAF can provide the dense, complex, and realistic signal environment necessary to evaluate integrated systems/subsystems to meet both Development Test and Evaluation (DT&E) and Operational Test and Evaluation (OT&E) objectives. The BAF, located at the Air Force Flight Test Center (AFFTC), Edwards Air Force Base, is part of the Avionics Test and Integration Complex (ATIC). The BAF is capable of supporting full-scale aerospace vehicles; such as, the F-3 Tornado, F-16, F-15, C-130, C-17, bombers, attack aircraft, and trainers and their associated EW systems. The BAF provides a quiet, secure, and controlled electromagnetic environment to test installed/integrated systems, their associated weapons, avionics and EW systems. This testing is accomplished within a very large anechoic chamber, providing a realistic free-space and controllable radio frequency (RF) environment. The BAF is an ideal ground test facility to investigate and evaluate anomalies associated with EW systems; avionics, tactical missiles, and their host platform. The BAF experience in EW evaluation includes, but is not limited to: electromagnetic interference (EMI)/electromagnetic compatibility (EMC), antenna pattern measurement, angle-of-arrival (AOA) measurement, electronic countermeasures (ECM) response and EW avionics integration.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.
