摘要
提出一种适用于光纤围栏系统的扰动事件判决算法。该算法基于短时能量对噪声信号进行实时评估,动态调整用于事件判决的上下阈值。通过外场试验数据验证了该算法不仅可以降低人工调试难度,而且对自然环境变化有良好的适应性。
This paper presents an algorithm of intrusion detection applied to fiber fence system. The algorithm uses short-time energy of noise signals in real time to adjust the up and down threshold of intrusion detection dynamically. The experiment results show that this algorithm can not only reduce the difficulty of debugging, but also have good adaptability to natural environment changing.
