Serial Communication for Variable Frequency Speed Regulation Monitor System Based on LabVIEW
Yan Lan-zhou · Electric Machines and Control Application · 2010
Serial communication for variable frequency speed regulation monitor system was introduced,which sent the voltage,current and speed collected by the DSP to the PC and sent the control instructions to the DSP through the serial port. At the same time,several kind of communicating method and choose an appropriate method according to this system were put forward. The PC uses LabVIEW programming ,with LabVIEW as developing platform,the PC can easily implement the functions of drawing the curves,data receiving,storage and analysis the operation status of variable frequency speed regulation system through waveforms at the front panel. Experimental results showed that the method of communication can meet the requirements.
