You are invited to submit a tender in response to RFT 1112-138 for a software engineer to assist Defence Science and Technology Organisation (DSTO) with the development of a coil impedance measurement instrument for use in Eddy current crack detection and to migrate the base software to a new, higher capability microprocessor.
DSTO has developed a number of networked sensor interfaces for structural and environmental monitoring. These include DSTO developed IP for both hardware and a microcontroller based software operating system.
One of these interfaces is designed to interrogate a single eddy-current coil at a single frequency and determine the complex impedance of the coil. When the coil is located on a metallic surface the complex impedance is a measure of cracking occurring underneath the coil. Currently this system can interrogate one coil.
The requirement is to interface the current single coil system with an array of coils and to extend the capability to multiple frequencies. DSTO has also upgraded the base hardware to a higher capability microprocessor. The requirement is to migrate and test the base software on the new hardware platform.
