基于局部离群点检测的机房区域入侵报警系统

Computer room area intrusion alarm system based on local outlier detection

为提高机房区域入侵报警的可靠性、准确性和实时性,基于局部离群点检测算法进行机房区域入侵报警系统多级化设计。应用数据采集服务器和传感器采集数据,形成一个数据帧发送至管理层;以管理层的数据库为数据支撑,结合多级化报警模块,完成数据的多层级处理;利用局部离群点检测算法,生成入侵报警信息并发送报警信息至应用层,完成机房区域入侵报警。实验结果表明:在压缩率为93.9%的情况下,报警数据可靠性较高,只需1.34s即可完成入侵报警发送,报警准确率均高于80%,误报率均在14%以下,可保证机房区域入侵报警效果。

In order to improve the reliability,accuracy and real-time of computer room area intrusion alarm,a multi-level design of computer room area intrusion alarm system is carried out based on local outlier detection algorithm.The data acquisition server and sensor are used to collect data to form a data frame and send it to the management layer.With the database of the management layer as the data support and combined with the multi-level alarm module,the multi-level processing of data is completed.The local outlier detection algorithm is used to generate intrusion alarm information and send the alarm information to the application layer to complete the intrusion alarm in the computer room area.The experiment results show that when the compression rate is 93.9%,the reliability of alarm data is high.The intrusion alarm can be sent in only 1.34s,the alarm accuracy is higher than 80%,and the false alarm rate is less than 14%,so as to ensure the intrusion alarm effect in the computer room area.
