Měření akustické emise

Abstract

The aim of this thesis is to introduce the principle of the method of acoustic emission and to design facilities for its measurement. This method is used for discovering potential material defects caused by stressing it. The device will operate on the basis of Actel programmable gate arrays with processor core and Ethernet interface for communication with host system. Gate array of SmartFusion family in collaboration with Cortex-M3 processor was chosen for the implementation. Actel company also provides the development environment Libero IDE which was used to implement the logic circuits into this array. This development environment includes the Model Sim simulator which enables the design functionality testing. Two programming languages were used: VHDL for the description of the hardware structure and C with SoftConsole IDE for CPU programming. I believe that this thesis has fulfilled its purpose, clarifies issues of acoustic emission and clearly explains my chosen method of the system implementation.
