Abstract

Internet/Intranet Simulation
A computer based eddy-current inspection simulator not only aides in the training and certification of eddy-current inspectors, it can be used over the Internet or in-house Intranet networks to train or examine inspectors at multiple or remote sites. This saves travel time and resources as defects, instrumentation and teaching can all be consolidated. Samples can be maintained and distributed from a central certification body providing more control and flexibility.

Approach


Figure 1 Client/Server E-C Simulation

All simulators work by providing a worldview as the user manipulates standard sets of controls. An eddy-current simulator falls neatly into the internet/intranet paradigm in that the work-piece worldview, shown on the right of Figure 1, can be the server. The eddy-current instrument worldview, shown on the left of Figure 1, is the client. The data file can also be provided over the network. The server can provide data, in our case signals, to clients on the same machine or on any machine on the network. This signal bandwidth is extremely small, allowing for voice and/or video signals to accompany the simulated probe signals over the network. A tutorial mode would allow the server to play back of "canned" inspections - where all probe movements are recorded. The clients would then be free to display the signals repeatedly using the tutorial's settings or modifying the settings independently.

Conclusion
Simulation allows operators to be trained on a wide variety of samples and probes without the expense of manufacturing or storing them. Simulators, married to Internet or Intranet networks, allow for simultaneous training or certification at multiple sites. Training and examinations can take place under a more controlled environment, where all the operators are using the same equipment and samples, making assessment and standardization easier.
