基于Android的用于光纤光栅信号解调的OCM检测系统

摘要

在光纤光栅传感系统中能够使用一台操作直观、精度高、成本低廉并且携带方便的光纤光栅信号解调仪显得尤为重要.文中将一款光道检测仪OCM(Optical Channel Monitor)应用于光纤光栅的信号测量,并在操作系统方面采用了Google Android操作系统,使用了Android NDK( Native Development Kit)和SDK( Software Development Kit)分别对linux内核和Android应用程序进行开发,实现了一种基于Android操作系统的OCM通信和控制系统,能够对光纤光栅所反射的中心波长进行实时准确的检测.%In practical application of fiber grating sensor system can use a single intuitive operation, high accuracy,low cost and light to carry instrument of fiber grating signal demodulator is important. This paper introduced an optical channel monitor (OCM)in fiber grating sensor signal demodulation,and chose to make the application based on Google Android operating system which is nowadays widely used in mobile devices.it achieved an OCM communication and control system that can detect the central wavelength of the FUG in real-time by using Android NDK and SDK in developing linux kernel and Android application respectively.
