本文主要提供一种基于光纤光栅周界报警系统的模式识别方法,其中方法包括以下步骤:当信号振动幅度大于某一阈值时,认为信号发生突变,记录突变信号后一段时间的振动数据,然后求取振动数据极值,并对其做阻力震荡衰减趋势拟合,得到拟合特征参数斜率和相关系数与设定阈值进行比较,从而达到对单次激励行为的识别。本文提供的模式识别方法识别周界动物碰触敏度高,抗环境能力强,系统报警性能好,误识别低。
本文主要提供一種基于光纖光柵週界報警繫統的模式識彆方法,其中方法包括以下步驟:噹信號振動幅度大于某一閾值時,認為信號髮生突變,記錄突變信號後一段時間的振動數據,然後求取振動數據極值,併對其做阻力震盪衰減趨勢擬閤,得到擬閤特徵參數斜率和相關繫數與設定閾值進行比較,從而達到對單次激勵行為的識彆。本文提供的模式識彆方法識彆週界動物踫觸敏度高,抗環境能力彊,繫統報警性能好,誤識彆低。

This paper provides a kind of pattern recognition method based on fiber Bragg grating perimeter alarm system.Method includes the following steps: when the signal is greater than a certain threshold,the signal is considered to mutate, record mutation signal after a period of vibration data,then vibration data extreme value is calculated,and its resistance to shock attenuation trend fitting.Characteristic parameters by fitting the slope and the correlation coefficient comparing with setting threshold,so as to achieve the recognition of a single motivation behavior.This article provides a pattern recognition method to identify perimeter animals touch sensitive degree is high,strong ability to resist the environment,the system alarm performance is good,low error identification.
