Aiming at rope jumping fault during operation of double rope winding hoist
a rope jumping fault diagnosis method of hoist based on empirical mode decomposition(EMD) and permutation entropy(PE) algorithm is proposed. The tension signal of wire rope under normal and fault conditions is decomposed into multiple intrinsic mode function(IMF) by EMD method
and the IMF components with fault information are calculated by PE as fault characteristics. By collecting tension signals under normal operation and rope jumping fault of the hoist test platform
the calculation results are obtained by using the above method. It is found that the PE value can be used as fault feature to judge whether rope jumping fault occurs or not
