摘要
A structural health monitoring system comprising intelligent sensors and serial communications devices interconnecting the sensors, data acquisition units and a programmable logic controller (PLC). The intelligent sensors are individually programmable and can be tuned to listen to specific frequencies based on a scaling factor based on the sensor's location in the system being monitored, a set of pre-known frequencies based on the sensor's location in the system being monitored, and the output of a central frequency-based system sensor. An aircraft flight control application of a method embodying the present invention includes anomaly detection based on comparing one or more preprogrammed flight plan regimen variables with actual aircraft performance parameters, and taking appropriate corrective action.
