Embodiment 1
[0065] like figure 1 As shown, it is a preferred implementation process of a method for intelligently predicting faults of a filling and packaging machine according to the present invention. The method is a method for intelligently predicting faults of filling and packaging machines based on domain adaptation and deep learning, and includes the following steps:
[0066] Step S1, the collection of vibration signal: utilize the acceleration sensor to collect the vibration signal of the filling and packaging machine transmission system as the source domain vibration signal, and use the acceleration sensor to collect the vibration signal of the required monitoring filling and packaging machine transmission system as the target domain vibration signal;
[0067] Step S2, the preprocessing of the vibration signal: the source domain vibration signal and its corresponding state label set use D s and y s Denotes that the target domain vibration signal and its corresponding state label ...
