Data acquisition and coding control
The prototype is built around Menard’s existing Omnibox data acquisition device which is designed to supply the relevant data for the project, track production and monitor quality. It is combined with pressure and elongation sensors that can be applied to any type of jack, and a tendon tensioning application to control the operation.
The predicted stress versus elongation of the tendon is reproduced on the screen of the operative’s tablet, viewed alongside real-time measurements obtained from sensors on the jacks that are connected to the Omnibox. This is particularly helpful in the final stages where there may be many small increments to apply and where there is more chance of human error.
The whole operation is logged centrally, and the system is set up so that quality control forms can be submitted direct to the client in digital format for sign-off.
