为了对各种防区进行实时监测, 准确分辨出入侵行为, 提出了一种基于非平衡马赫-曾德尔结构干涉原理的全光纤防区型周界报警系统。对这种干涉结构进行了理论分析和实验验证, 并在LabVIEW平台上开发了基于此传感结构的防区报警软件, 在运行10d内, 此系统准确报警率达95.1%。结果表明, 此系统对突发事件有较好的模式识别能力, 该结构在防区报警系统方面具有较好的效果。

In older to monitor all kinds of regional perimeter and identify the intrusion accurately, an all-fiber regional perimeter alarm system was presented based on the non-equilibrium Mach-Zehnder interference. Theoretical analysis and experiments were carried out. The alarm software was developed on the labview platform. The alarm rate of the system reached 95.1% in ten days so that it could distinguish emergencies efficiently and could be used in perimeter alarm system.
