[0060] Example
[0061] The method for evaluating and predicting the health status of equipment based on industrial big data described in this example is as follows: figure 1 with image 3 , Mainly includes the following parts:
[0062] S1. First select several sets of relatively complete run-to-failure full life cycle data from the equipment state data set, and select characteristic parameters that can characterize the equipment degradation state and can be continuously monitored and recorded as equipment degradation variables. Different types of industrial equipment can choose their own parameters to be monitored, mainly including speed, flow rate, pressure, temperature, power, current, etc.
[0063] S2. Perform effective data preprocessing for data-related degraded variables, including normalization and feature reduction based on principal component analysis, and eliminate redundant variables in sample data;
[0064] Among them, the normalization adopts the maximum and minimum nor...
