Abstract:

For online monitoring of complex equipment, a novel method for equipment state evaluation is proposed. Firstly, according to the desired point of the equipment, the central symmetrical sample set is obtained, and then the original sample and the symmetrical sample are combined as one target sample set. Secondly, the depth of the current status with respect to the target sample is taken as the performance evaluation result. Finally, for the functional data, the evaluation result at the same moment is obtained with the multivariate date method and then the average result is obtained with the integral method along the time axis. The experimental results show the validity of the methods.
