针对当前光纤周界入侵振动信号检测系统检测能力低、成本高、无法对未知攻击做出有效识别的不足,提出一种光纤周界入侵振动信号嵌入式实时检测系统。入侵振动信号实时检测系统充分利用嵌入式设计低功耗、低成本和高性能的特点,增强了系统检测的性能。检测系统的硬件设计方面,主要包括信号采集模块、信号处理模块和入侵检测模块;基于系统的硬件架构,设计了实时检测系统的软件部分,并介绍了基于聚类分析算法的入侵信号规则的提取和入侵检测的实现流程。仿真实验证明提出的入侵振动信号系统设计,具有较好的检测能力和较低的误检率,同时在系统稳定性方面也有良好的表现。
In order to overcome the shortcomings of low detectability, high cost and inability to identify unknown attack effectively, an embedded real-time detection system of optical fiber perimeter intrusion signal is proposed. Real-time detection system of intrusion vibration signal takes full advantage of the low power consumption, low cost and high performance of embedded design, which enhances the performance of system detection. The hardware design of the detection system mainly includes signal acquisition module, signal processing module and intrusion detection module. Based on the hardware architecture of the system, the software part of the real-time detection system is designed and the rules of intrusion detection based on clustering analysis algorithm are introduced And intrusion detection process. Simulation results show that the proposed intrusion vibration signal system design has better detection ability and lower false detection rate, and also has good performance in system stability.
