摘要
随着对温度和形变的在线测量的需求日益提高,FBG技术已经被应用于温度及形变测量中。讨论了FBG传感器信号的快速获取,设计了基于AlteraNios平台的光信号采集SOPC系统,详细地分析了本系统中各个组成部分的工作原理,包括光信号获取、光电信号转换、模数转换以及Nios片上系统获取信号的整个过程。与目前具有同样功能的其它测量系统相比,它具有灵活、稳定、易维护、高效率等优点。
With the enhancing requirements of on-line measurement, FBG technique has been applied in the measurement of the temperature and shape change. Fast signal acquisition by FBG is discussed and an optical signal acquisition SOPC system based on Altera Nios platform is designed.The working principles of all parts in the system, including optical signal acquisition, optical-to-electric signal conversion, analog-to-digital signal conversion and signal acquisition by Nios SOPC are analyzed.Compared with other measurement system, this SOPC shows us flexibility,stability,easy-maintainability and high-efficiency.
