The measurement of ship vibration will bring on large quantities of data
a lot of data must be compressed due to the constraints of trigger mode and memory capacity.The redundancy and compression entropy of run-length encoding are analysed by theoretics
the relationship between external noise and the resolution of AD are also analysed and the algorithm is used in the actual ship vibration detection
the experiments show that the compression effect of algorithm is affected by changing speed of the measured signal
characteristics of the channel noise.The compression effect is remarkable in actual dynamic data compression.
