Laboratorní úlohy pro výuku Virtuální instrumentace s NI VIRTUAL BENCH

Abstract

The content of this bachelor thesis is the design and implementation of laboratory tasks for teaching Virtual Instrumentation. Laboratory tasks deal with parallel and non-parallel product testing. Two printed circuit boards were provided for the implementation of this work. The first board is a multiplexer laboratory switch, which is used to switch measuring instruments between the tested modules. With suitable control of the switch by the test SW, the testing time is shortened, which is very important in industrial production. The second board contains four identical tested products, referred to in the work as UUT. Each UUT contains four different tested modules. Testing of individual modules is performed using the NI VirtualBench device, which contains the five most frequently used devices in one cabinet. Laboratory tasks are programmed in the LabVIEW graphical programming environment. The main task is parallel testing. The non-parallel testing task is created for the purpose of time comparison of test lengths.
