Wykorzystanie w dydaktyce rekonfigurowalnych przyrządów pomiarowo-sterujących i systemów wbudowanych

Artykuł przedstawia dwie platformy sprzętowe stosowane w laboratorium studenckim. Pierwszą z nich jest rekonfigurowalny system RIO firmy National Instruments, drugą - płyta rozwojowa przeznaczona do rozwoju oprogramowania wbudowanego do węzłów sieci czujnikowych i komputerowej akwizycji danych. Obie platformy pozwalają na projektowanie urządzeń z systemami wbudowanymi (również czasu rzeczywistego) jako elementów większych, rozproszonych systemów pomiarowo-sterujących (RSPS).

The paper presents two hardware platforms used for didactic purposes in a student laboratory. The first one is a reconfigurable system by the National Instruments CompactRIO. It is an industrial computer aimed at automation and control of processes, for example during diagnostic procedures and in the factory production. As NI solutions often become worldwide standards, it is reasonable to train future engineers in programming their systems. With CompactRIO, the main effort of a designer is to create reliable applications working in the Real-Time mode. The second platform is an evaluation board usually applied as a node in the sensory network or to the computer data acquisition. The main problem here is the FPGA array configuration to perform measuring and controlling tasks. Both solutions can be used to design embedded systems being a part of larger systems. The paper presents the structure and architecture of both devices, including description of programming methodologies. Technical characteristics of both devices are described in detail, revealing their advantages and limitations. Then, applications to the process of engineer education are presented, based on the examples from the Institute of Radioelectronics, Warsaw University of Technology. These include both laboratory exercises and student projects, where they can solve particular engineering tasks using the presented hardware. The paper is supplemented with conclusions and future prospects of the introduced systems in didactics.
