ADuC824在光纤光栅传感复用网络中的应用

Application of ADuC824 in Fiber Bragg Grating Sensing Network

采用高性价比的ADuC824微处理器作为核心控制部件,利用可调谐窄带滤波器作波长解调器件,设计实现了多点光纤光栅传感复用网络系统。采用了波分及空分复用技术,由多个光纤光栅传感器构成分布式传感网络。可对各传感光纤光栅进行静态或动态的波长解调,具有结构简单、操作方便和性能价格比高的优点。在实际应用中,可以利用这一解调方案代替光谱分析仪或其他价格昂贵的波长检测仪器,对光纤光栅传感信息进行现场测量。

Designed and demonstracted a multipoint Fiber Bragg Grating(FBG)sensor multiplexed network system,took the microprocessor ADuC824 with high price quality as the core control unit,utilized the tunable narrow-bandwidth optical filter as the wavelength demodulation component.The system is composed of multi-FBG sensors,and it uses the technology of wave-division-multiplex(WDM)and space-division-multiplex(SDM)in composing the disturb sensor network.The system can demodulate the wavelength of every FBG sensor statically or dynamically;it has the outstanding feature of simply structure,flexible operation and high price quality.In actual application,use the demodulation scheme to replace the optical spectrum analyzer(OSA)or other expensive wavelength analysis instrument in field measuring the information of FBG sensor.
