During the development and maintenance of engine software test programs used by the three systems a certain amount of on-site engine run time is required to develop, test and verify software changes. This on-site time is costly in TDY, contractor site visits, engine fuel used, man-hours and missed production time of the test cell. A real-time simulation of the engine with concurrent signals and stimulus that match test cell transducers would replace the on-site runtime needed of the engine and test cell crew. SAALC/LDAD, the engine tester program management office, has placed CACI International, Inc. on contract to produce a Real-Time, Multiple Signal, Dynamic Engine Simulator (RTMSDES) from COTS hardware and software. The program management office's goal is to develop a dynamic, real-time simultaneous set of stimuli for the engine testers mentioned above for software maintenance and development personnel. This paper details the COTS solution we are developing using, the latest VXIbus technology. Topics discussed include the methods we used to simulate the real-time stimulus of engines as well the selection of COTS hardware required to perform the stimulus. The paper also discusses our implementation of LabView 4.01 as the simulation software environment, and Windows NT as the operating system.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

The focus is on providing information to facilitate the use of viable techniques suited for a problem definition. The level of understanding of the analog system is correlated with the type of techniques best suited for the diagnostic system. Reviewed are techniques from Control Theory, Probability Theory, Computational Expert Systems, and Computational Artificial intelligence. The Control Theory techniques are suited best for system diagnostic problems where the system model is accurately understood. Techniques that employ Probability Theory are valuable for addressing uncertainty that arises in diagnostics of systems affected by noise. Computational Expert Systems address the problem of diagnostics by creating a data situations where the diagnostic process is accurately understood. Computational Artificial Intelligence techniques are presented as being best suited for systems where little reliable knowledge is known. The analysis does not preclude the use of any technique, but rather addresses efficiency of application.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

Expert systems have developed and matured over the past several years to become a viable tool capable of functioning as a procedural tool for identifying diagnostic requirements, analyzing test system capabilities, and providing seamless diagnostic data transfer from requirement to analysis to operations. The most important differentiating characteristics of expert systems are their modeling methods, and their architecture. The modeling method drastically affects the time required to build a model, and the architecture must be open enough to integrate with the many tools used in engineering, deployment, and maintenance of the supported equipment throughout its life cycle. In this article, we present the Fault Modeling method, which has been field-proven over the past decade as flexible enough to meet the challenges of different lifecycle tasks, as well as lending itself to learning-self-improvement over time, even when starting with no knowledge. Expert systems using this model feature rapid deployment, and are able to cover the entire ID process including: capture of existing data, analysis of fault detection and isolation capabilities of the unit under test, and a means to assess diagnostic system designs early in the development phase. The systems integrate easily with simulators, automatic test equipment (ATE), and portable maintenance aid (PMA) equipment.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

This modeling technique also provides a standard to which existing and future ATEs and UUTs can be modeled and used for analysis and comparisons. The signal-based model is implemented via a Structured Query Language (SQL) Relational Data Base Management System (RDBMS). COTS Rapid Application Development (RAD) tools, such as Microsoft/sup (R)/ Visual Basic/sup (R)/ Microsoft Access/sup (R)/ and PowerBuilder/sup (R)/, are employed to implement interfaces to the SQL database model and to provide the necessary algorithms for data comparison, model reuse and other manipulations of the model data. After models are established for both the ATE and UUTs, ATU/UUT compatibility analysis can be performed to identify any potential incompatibilities. This information can be used to optimize the selection of a target ATE for a selected group of UUTs. It can also be used to identify any signal deficiencies in the target ATE that require ATE enhancements or Interface Test Adapter (ITA) signal conditioning, to ensure UUT compatibility.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.

Users are mainly interested in collecting test data to monitor performance of existing systems for future modifications due to demands imposed by users requirements. This is normally achieved through a series of instrumented test nights that telemeter data of interest to a night centre. The prime concern of this research work is the efficient utilisation of telemetry frame formats known as the Data Cycle Map (DCM). DCM represents parameters sampled at different rates during night testing compliant to a telemetry standard known as the Inter Range instrumentation Group (IRIG). In a previously reported research work, the author presented a methodology based on algorithms similar to those adopted in memory management techniques within a multi-environment operating systems to optimally utilise the space allocation for a telemetry frame. In this paper, the author adopts the previous work in an interactive user-friendly environment using Visual C++. This approach, will provide users with visualisation and flexibility to choose between different Past or intermediate DCM in a more efficient approach. The framework provides an effective DCM utilisation, yet requires the intervention of the user.","PeriodicalId":369132,"journal":{"name":"1997 IEEE Autotestcon Proceedings AUTOTESTCON '97.
