A Method for Analyzing Parameter Measurements to Track Dangerous Changes in a Technical Object

Improving the safety level of technical facilities is associated with a reliable assessment of the condition of the facility, which should be adequate to the situation that has arisen. Often for this assessment, you can choose one characteristic parameter that determines the state of the object as a whole. The paper shows the possibility of using Poincare diagrams to track changes in the state of a technical object in real time. Poincare diagrams of any dynamic processes are characterized by asymmetry with respect to the center or axes of the coordinate system. In the modeling process, a time shift procedure is used for a limited array of elements of the time series, which consists of parameter values. The structure of a generalized one-factor model for tracking changes in the state of an object based on an analysis of changes in Poincare diagrams is proposed. Assessment of the state of the object is based on the analysis of the spread of the points of the array on the diagram relative to the center of mass at each time point
