The conception of multi-scale Hilbert spectrum entropy (MSHSE) was proposed based on the multi-scale analysis character of the local wave method (LWM) and its calculation method was developed. MSHSE was applied to the fault diagnosis of reciprocating compressor valves. By comparing with time-frequency entropy, MSHSE is proved to be more accurate in revealing the machine status.
