The Design of Re-Issued Data Memory Circuit Based on Telemetry System

Abstract:

Radio telemetry is used as a major way on monitoring flight test of airplanes. As information transition channel is disturbed or interrupted significantly during the blackout area during flight, the carrier information will not be transmitted normally. However, the airplane data during the blackout period has to be monitored seriously. This issue can be resolved by building re-issued data memory function into a telemetry system. This paper looks at the research of re-issued data memory technology and proposes a new design of re-issued data memory circuit for realizing the negative trigger delay storage of data flow in telemetry system during blackout period. The delayed data in the storage will be transmitted again later. The new designed circuit uses multiple re-issued data memory methods to satisfy the requirements of different telemetry tests and measurements, assuring complete data during airplane flight test.
