摘要
本文介绍了基于光纤振动传感器的周界防范装置,该装置的工作机理是利用光缆受到外界侵入而振动,产生光学拍频现象,通过对波形分析与识别,实现周界防范的功能。本文通过该试验装置的研究,探讨了利用光纤技术构建智能周界报警系统的可能性。
The article analyzes the research of circumferential defense system based on optical fiber vibration sensor. As the first line of safety defense system, the circumjacent alarm system plays a very important role. When the fiber is invaded from outside and causes vibration, optical beat phenomenon appears, therefore a set of fiber circumferential defense device is designed depending on this principle. Finally, the article proves that intelligent circumjacent alarm system which adopts fiber technology owns great advantages and has become a indispensable part in intelligent building.
