采用虚拟仪器技术的OTDR的设计与实现

The Designing and Implementation of OTDR by Using Virtual Instrument Technology

为了克服传统的OTDR价格昂贵、难以进行实时监控等缺点,本文提出了采用虚拟仪器技术设计新型的基于PC机的OTDR方案。该系统采用PC-DAQ体系结构,由数据采集卡和数据处理软件两大部分构成。文中介绍了系统整体设计方案,并对系统的硬件和软件设计分别进行了详细论述。

To avoid the flaws of the traditional OTDR such as costliness and inapplicability in real time monitoring, a new-style OTDR that based on Virtual Instruments technology is put forward in this paper. It commonly consists of data acquisition card and data process program. In this paper, the overall system structure is introduced, and then both of the hardware and software implementation are put forward.
