中文摘要: 随着经济的快速发展,社会安全也随之变得相当重要,同时一些犯罪分子所采用的犯罪手段也是更加复杂以及高科技;而传统的安防措施大多采用电传感或依靠人力监视,已经无法有效的保证人们的财产以及人身安全.因此,本文提出一种基于双M-Z结构的光纤周界系统,利用光纤的特性进行干扰信号的模式识别,再利用整个周界系统的特殊结构对干扰信号进行高效率的响应以及报警,甚至可以完成准确定位功能.通过对信号处理技术,增大了采集信号的信噪比,实现了良好的识别率以及较高的定位准确率.
中文关键词: 光纤周界  模式识别  双M-Z  定位
Abstract:With the rapid development of the economy, social security has become quite important. At the same time, the criminal methods used by criminals are more complicated and high-tech. Traditional security measures are mostly based on electrical sensing or relying on human surveillance, and are hard to guarantee people's property and personal safety effectively. Therefore, this study proposes a fiber perimeter system based on double M-Z structure, which uses the characteristics of the fiber to identify the pattern of interference signal, and then uses the special structure of entire perimeter system to respond to the interference signal with high efficiency and alarm, and even complete accurate positioning function. Through the signal processing technology, the signal-to-noise ratio of the acquired signal is increased, and a good recognition rate and a high positioning accuracy are achieved.
