基于虚拟仪器的光时域反射仪自动测试系统

Auto-measuring System for OTDR Based on Virtual Instrument

利用现有的光时域反射仪(OTDR)光通信测量设备,采用虚拟仪器技术,组建基于虚拟仪器的光时域反射仪自动测试系统。该系统借助Labview开发平台在计算机屏幕上形成软面板来进行控制和操作仪器,来提高仪器的自动化程度和适应性,并使系统具有很强的数据采集和处理能力,并为如何有效地维护仪器和拓宽旧仪表的功能提供了一个行之有效的方法。

Based on the study of the OTDR and virtual instrument technology, a new type of OTDR auto-mea-suring system was generated, the instrumental function has been developed, the level of automation has been raised, and the adaptability has been enhanced. Being integrated with LabVIEW, the system has been provided with powerful function for data acquisition and processing, and can offer an effective way about how to maintain instrument and develop the older instrumental function.
