Cable system health monitoring method based on strain monitoring cable structure
InactiveCN101334275AMonitor and evaluate health statusReduce distortionStructural/machines measurementComplex mathematical operationsReference modelMulti objective optimization algorithm
The invention discloses a health monitoring system of a cable system in a cable structure on the basis of strain monitoring; a plurality of times of mechanical calculation is carried out on the basis of the reference model of the mechanical calculation of a structure, the times of the calculation is equal to the number of cables. Supposing that only one cable has unit damage during each calculation, the calculation result of each time constitutes a current strain calculation vector; a strain change vector is obtained by that each current strain calculation vector minus an initial strain vector; all the strain change vectors constitute a unit damage strain change matrix. According to the similar linear relation between the current strain vector (constituted by the current measured strain of all the given points) and the initial strain vector, the unit damage strain change matrix, an unit damage scalar and a current cable damage vector (constituted by current damage amount of all cables), the noninferior solution of the current cable damage vector can be figured out fast by utilizing the suitable algorithms of multi-objective optimization algorithm, etc., therefore, the position and the degree of damage of the damaged cable can be determined accurately.

System and method for outlier detection via estimating clusters
ActiveUS9336484B1Suitable weightAvoiding complexity and expenseDigital computer detailsRelational databasesAnomaly detectionOutlier
An efficient method and system for real-time or offline analysis of multivariate sensor data for use in anomaly detection, fault detection, and system health monitoring is provided. Models automatically derived from training data, typically nominal system data acquired from sensors in normally operating conditions or from detailed simulations, are used to identify unusual, out of family data samples (outliers) that indicate possible system failure or degradation. Outliers are determined through analyzing a degree of deviation of current system behavior from the models formed from the nominal system data. The deviation of current system behavior is presented as an easy to interpret numerical score along with a measure of the relative contribution of each system parameter to any off-nominal deviation. The techniques described herein may also be used to “clean” the training data.

Monitoring the health of a system module can be carried out during state transitioning, for example when starting or stopping a system module. A monitor module can be operationally connected to the system module. The system module can output a status signal for predetermined system status points during state transitioning. The monitor module can start a timer on detecting a first status signal and can reset the timer on detecting a subsequent status signal. The timer can indicate a failed transitioning of the system module in the event that the timer is not reset within a determined period of being reset.

Capacitance-based system health monitoring system, apparatus and method for layered structure
The present disclosure endeavors to provide an SHM system and method using a conductive material (e.g., CNT) to measure changes in a layered structure. Change in capacitance of a layered structure may be measured over time thereby indicating a change in the structural integrity of the material. The SHM system may be embedded with, or within, the layered structure such that the system is effectively part of the material. Alternatively, it may be external to the layered structure such that the system is a separate device used to measure the capacitance. The SHM system may also localize any changes in a layered structure by using, for example, strips or panels of conductive material on opposite sides of the layered structure being measured. Damage within overlapping portions of the conductive material provides localization capability where varying the size of the strips or panels may be use to vary the sensitivity and resolution of both the locations and size of the defect.
