基于阻抗变化分析的刺绳围栏周界警戒与隔离技术研究

Study on perimeter surveillance and isolation technique based on impedance variation analysis of electric fence

提出了一种基于阻抗变化分析的刺绳围栏入侵行为探测方法,直接利用现有隔离围栏的刺绳纬线为探测传感器探测外部入侵破坏行为,并通过分析栅栏纬线在一定观察周期内的阻抗变化来实现外部入侵行为的定性与分类识别,实现了传统周界物理隔离与现代周界警戒技术的完美结合。通过前期验证性实验证明了该技术的有效性与可行性,在关键区域的周界警戒与周界隔离等安防需求领域具有广阔的应用前景。

A novel technique of intrusion detection based on impedance variation analysis and woof loop sensor with barbed wire is proposed, which uses the woof loop of barbed wire fence as the senor to detect intrusions directly. Detection and classification of intrusions could be implemented by observations of the impedance variation analysis of woof loop sensor within a period of time. The technique has all the advantages as the traditional barbed-wire fence and modern electric fence. The effectiveness and feasibility of the technique were verified through a series of experiments. There would be broad application prospects for the technique in the perimeter surveillance and isolation fields in the future.
