Modular PC Based System for Educational Laboratory Experiments
Author:
Abstract: This article concerns a modular automated system for conducting student laboratory experiments, which contains two parts: hardware and software. The hardware part is made up of PC and laboratory training kit with a constant analog/digital periphery and removable module (different for each experiment). The software part comprises two independent and complimentary subsystems: menu-oriented software and specialized language. Menu based system offers various research functions as a capture of transfer characteristic, printing, saving, etc. On the other hand, the specialized language for conducting laboratory experiments ULLE offers a possibility to draw up research programs, by using the stimulus-response method. It is implemented as a resident driver usesing the so-called conception of ""live variables”. When declaring a type of I/O variable (for connection to the laboratory training kits), its address is transmitted to the driver. By means of a periodic hardware interrupt, the driver performs auto-refresh of the I/O channels (of the hardware laboratory kit) and the associated I/O variables. Due to the fact the driver receives only the address of the variable, it can be run with programs written in different programming languages.
