APPLYING IEEE 1451 STANDARD TO AATIS

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, NevadaCurrent legacy acquisition systems such as the Advanced Airborne Test Instrumentation System (AATIS) are custom-built to each individual application with unique sensors and data modules. Replacing, adding, or subtracting sensors requires the system to be removed from service for days, weeks, or even months. This is a result of having to route special wires to each sensor and reprogramming the system with sensor information, calibration data, etc. AR sensor information must be contained in the main system since these systems do not have intelligence at the sensor level. If sensors were to contain information in their own IEEE 1451-compliant transducer electronic data sheet (TEDS), the main system would no longer have to be reprogrammed with this information. This information could then be obtained directly from the sensors when they are inserted into the system. A plug-n-play capability is being added to the system with the development of a standard interface to the system control unit (SCU). This interface, called a Multi-Network Capable Applications Processor (Multi-NCAP), will interface IEEE 1451-compliant smart transducer interface modules (STIMs) to the SCU in the AATIS as well as other legacy systems. With this development, maintenance and new configuration times for the AATIS and other legacy systems will be significantly reduced.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
