Telemetry Time Integration

摘要

A new systems hardware and software architecture is presented. Time- tagging is accomplished on multiple packets of information flowing concurrently at extremely high data rates. In the telemetry field to date, there has been a serious problem with the inability to properly time-tag multiple incoming data elements simultaneously. It is crucial when flight testing missiles or other aircraft to determine precisely the sequence of events. The hierarchical modified dataflow architecture contains a supervisor module which manages an Inter-Range Instrumentation Group (IRIG) Time Acquisition Module and several acquisition and processing modules within a system. The high speed serial bussing techniques utilized allow the time module to source time information to any one or all of the other modules simultaneously. Each module operates autonomously and time-tagging is allowed at any intermediate stage of processing. Archiving of data with the time tag allows high speed retrieval and processing of time 'slices' of data. Temporal inter-relationships between many thousands of data types is determinable in real-time or post-processing.
