DERIVED PARAMETER IMPLEMENTATION IN A TELEMETRY PREPROCESSOR

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaToday’s telemetry preprocessing systems are often required to create and process new telemetry parameters by combining multiple actual parameters in a telemetry data stream. The newly created parameters are commonly referred to as “derived parameters” and are often required for analysis in real time at relatively high speeds. Derived parameters are created through algebraic or logical combinations of multiple parameters distributed throughout the telemetry data frame. Creation and processing of derived parameters is frequently performed in telemetry system preprocessors, which are much more efficient at processing time division multiplex data streams than general purpose processors. Providing telemetry system users with a “user friendly” method for creating and installing newly derived parameter functions has been a subject of considerable discussion. Successful implementation of derived parameter processing has typically required the telemetry system user to be knowledgeable of the telemetry preprocessor architecture and to possess software programming skills. An innovative technique which requires no programming language skills is presented in this paper. Programmers or non-programmers may use the technique to easily define derived parameter calculations. Both single derived parameters and multiple derived parameters may be calculated in the preprocessor at high throughput rates.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
