光纤在线监测系统的研究和实现

Research and Implementation of Optical Fiber On-Line Monitoring Systems

研究了光源、光功率计和OTDR卡等设备在软件系统控制下自动实现光缆在线实时监测技术,通过C++语言设计一套功能强大的软件系统,给出了设计原理和实现方法,利用GIS、PCI总线等手段加强了现有光缆监测直观性和实时性的不足,提出一种基于数据库管理和网间通信的软件架构。应用结果表明,通过软件系统控制光源、光功率计和OTDR卡等设备实现光纤在线监测功能的方法可行。

The light source,optical power meter and OTDR cards will be controlled by the software system to achieve automatic online real-time monitoring of optical cable. C ＋ ＋ language was used to design a powerful software system and the design principle and implementation method were given. Measures were taken such as using of GIS and PCI bus to make up the monitoring and real time deficiency of existing cables. Software architecture based on database management and internetwork communication was proposed. The application results show that the use of software sys- tem to control light source,optical power meter and OTDR cards to achieve on-line monitoring function is feasible.
