Embodiment Construction
[0045] Such as figure 1 As shown, the on-line monitoring method of the vibration state of the high-voltage motor driving the conveyor belt of the present invention comprises the following steps:
[0046] Step 1. Install vibration sensors for outputting vibration signals on each bearing seat of the high-voltage motor, and collect the original vibration signals output by the vibration sensors X i , for the original vibration signal X i Perform frequency spectrum analysis to extract the vibration characteristic signal of the high-voltage motor. The total vibration value A of the original vibration signal is determined by the discrete value X of the vibration signal i (i=1,2,……,N) get,
[0047] A = Σ i - 1 N ( | ...
