| Abstract: | The main characteristic of fault messages by reducing its dimensions through matrix conversion in the principal component analysis, and the fault of combustion function of locomotive disel engine is analyzed. Illustrated by an example, the paper proposes an approach which can concentrate fault information without influencing analytical results under the condition that the loss of useful messages is relatively small. It can also be a simple and effective statistical recognition method to solve multi-variable and multi-dimensional complicated system. |
