摘要
介绍了一种基于USB的同步相量测量装置(PMU)的数据通信方式设计,阐述了PMU装置中USB通信模块的设计过程,给出了固件程序、驱动程序以及应用软件设计方法,同时提出了USB的远程扩展技术,可实现PMU相量数据的远程传输。采用USB总线技术实现PMU与现场工控机的数据传输,既满足其可靠的高速传输要求,又使得PMU可脱离上位机而独立运行。
This paper introduces a design of communication mode based on USB for Phasor Measurement Unit (PMU). It describes the design process of USB communication module in PMU and puts forwards the design method of firmware program, drives and application software. It also realizes the remote transmission of PMU data by using USB remote expansion technology. The adoption of USB technology can not only satisfy the requirement of high speed transmission of PMU data but also keep PMU running independently without computer.
