摘要

This paper designs monitor software in experimental variable-speed system of AC motors. The monitor software realizes the real-time and visual control of AC motors through PC operation. It communicates with DSP program through serial port. It can setup the serial port and DSP parameters before the system's start-up, and receive experimental data from DSP when the system is running. In addition, it can display and save experimental data conveniently. Finally, experimental test is carried out. Experimental results verify that the proposed monitor software has powerful and general-purpose functions, and friendly user interface.
