The research for tribology by system method and the condition recognition for the tribology system;

The main characteristics of condition identification for free span(CIFS) are discussed firstly.

Feature extraction is important to machine state identification.

In this paper,a three-level multi-task distributive information pro- cessing system is developed,which consists of a realtime state identification system,a state analysis system and an expert system.

In the health monitoring of long-span bridges,the adverse changes of the internal force state are the major factor to damage the safe of bridge structures,so, the state identification subsystem is the key part of the health mornitoring system of bridge structures.
