摘　　要：全光纤周界安防系统对外界的感知与识别能力决定着安防效果,为了提升安防系统的性能,设计基于模式识别的全光纤周界安防系统。介绍系统高效率的模式识别安防机理,利用小波变换和全相滤波芯片分别在正常环境下和恶劣天气环境下进行环境信息的时域处理与模式识别,并对安防过程进行了详细描述,同时设计出系统基础结构和功能结构。实验结果证明,所设计系统能够快速、准确地提取环境信息时域特征,且模式识别结果受环境干扰的影响较小,警报结果可靠性强。The outside perception and recognition ability of all fiber perimeter security system determines the security effect.In order to improve the performance of the security system,all fiber perimeter security system was designed based on pattern recognition.This paper introduced the high efficiency pattern recognition security mechanism： use wavelet transform and phase filter chip to time domain and pattern recognition of the information in the normal and severe weather conditions respectively,and the security process is described in detail.Simultaneously,design system basic and functional structures.The experimental results show that the designed system can quickly and accurately extract the time domain characteristics of environmental information,the results of pattern recognition are less affected by environmental interference,and the reliability of the alarm results is strong.
