Description

technical field

[0001] The invention belongs to the field of telemetry, and relates to a method for realizing telemetry shock data compression and a system for realizing the method. Background technique

[0002] Since the impact environment may cause structural failure, short cracking or breaking of components, and instantaneous short circuit of electronic equipment, a telemetry system is required to monitor the impact environment in order to provide a basis for impact environment control, protection and product environmental resistance design. Telemetry systems generally use piezoelectric acceleration sensors to directly measure shock waves. The shock signals output by piezoelectric acceleration sensors are random signals. For missiles and launch vehicles, the frequency range of shock signal measurement is generally 20 Hz to 5,000 Hz, and the sampling frequency is generally greater than 20,000 Hz. Hertz, assuming that 10-bit encoding is used, the transmission of one channel...
