基于虚拟仪器的电机转速检测系统

Electrical Machinery Rotational Speed Testing System Based on Virtual Instrument

基于美国NI公司的LabVIEW图形化编程语言,针对电机参数的检测进行虚拟仪器编程设计,开发出电动机转速和机电时间常数的在线测试系统.该系统分为人机界面,功能模块和外部电路三部分,改进了传统仪器在显示、储存、读取方面的限制.

Based on Labview graph-oriented program developed by American NI Company, and the virtual instrument program according to motor parameter detecting, this paper develops an on-line testing system to detect the electrical machinery rotational speed and electron mechanical time constant. This system includes three parts such as human-computer interface, functional module, and external circuit. It is more practical and cheaper than traditional testing system. At the same time, this system breaks through many limitations of traditional one in display, storage and fetch of datas.
