WIRELESS SENSOR AND DATA MANAGEMENT SYSTEM AND METHOD FOR MONITORING THE INTEGRITY OF MECHANICAL STRUCTURES

摘要

A method and apparatus for inspecting a wall of a mechanical structure including obtaining an infinite response from a sample material having a front face, a thickness, and a back wall, by transmitting into a sample material an ultrasonic wave having a frequency and duration and being generated by one or more transducers, wherein the thickness of the sample material is sufficiently great that only a wave corresponding to the front face of the sample is received back; transmitting an ultrasonic wave generated by one or more transducers into the wall of a mechanical structure to be inspected at a time (T), wherein the ultrasonic wave has the same frequency and duration as the ultrasonic wave transmitted into the sample material; receiving a response signal back from the wall to be inspected; and correlating the response signal to the infinite response, thereby creating correlated data. The system can be operated remotely and wirelessly, and data can be transmitted and received via the Internet or local area network, either wireless or wired.
