LabVIEW在OCT电网电流测试平台上的应用

Measurement and Control System Based on LabVIEW and OCT

介绍了LabVIEW语言的优点以及程序基于数据流驱动设计的特点和用于监控电网电流的OCT电流测试系统的各个模块。以光电互感器、精密模拟微控制器ADuC7026、计算机为主要硬件,LabVIEW为软件开发平台构建了用于实现信号的采集、存储、处理、分析、显示的多功能虚拟仪器系统,并使用并行处理的方式对其进行优化。该系统适用于电力系统的监控,成本低、功能可扩充性好、人机界面友好,对软件的维护比较方便。

The advantage of the LabVIEW language and the modules of the current measure system is introduced in this article. The design about this language is based on data stream driving. A virtual instrumentation is set up with the language of LabVIEW, by using computer, OCT sensor and Precision Analog Mieroeontroller ADUCT026. This multifunetional virtual instrumentation can realize signal acquisition, and storage, processing, analysis and data display. The system is optimized by the method of Parallel Algorithm. The system is suitable for supervision of power control system. Reducing the cost of the equipment, the system can also provide a friendly human-machine interface. In addition, it is convenient for the system maintenance and function expansion.
