基于嵌入式平台的网络化OTDR模拟训练系统设计

摘要

介绍了一种网络通信技术和实物模拟相结合的光时域反射仪（OTDR）模拟训练系统设计方法。系统采用虚拟的方式实现光缆线路特性与故障的生成，无需建设专用线路训练场地和光缆线路的采购与破坏；而光时域反射仪的人机交互和测量显示又采用实物形式模拟，提高了模拟仿真训练系统的真实性；整个系统可以实现较低成本的逼真训练。%Adesigning method of networked simulation training system for using Optical Time Domain Reflectometer (OTDR) is introduced. The system uses a virtual way to achieve optical cable line’s characteristics and faultgeneration, without building a dedicated line training grounds andthedestructionof theactualcableline.The OTDR’s human-computer interaction and display uses physical form simulation to improve the simulation authenticity. Finally, the system can achieve realistic training in a lower cost.
