摘要
结合机场的地域特征,介绍一种检测人入侵行为的设计方案。以激光光电感应作为传感器件,通过对89C52单片机进行C语言编程,检测和判断人入侵事件。通过大量实验获取样本时间点,利用聚类分析的算法有效排除掉噪声点,得到可靠样本空间,计算出可信赖样本阈值范围,经实验验证入侵判断误报率符合要求。
Based on the airport characteristic, this paper introduces a design program d people intrusion detection. This system uses laser photoelectric as sensors, in which single- chip 89C52 is conducted C language pvogranmming to judge and detect the intrusion events. Sampies are obtained by many experiments and the cluster analysis algorithm is used to effectively eliminate noise, to find out reliable sample space and calculate sample value which can be trusted. Invasion judignent about the rate of false alarm meets the requirement which is verified by experiment.
