摘要
结合长期的地震台站仪器维护实践和对常见的前兆仪器故障进行分析的基础上,针对当前前兆仪器故障监测的现状,文章提出设计一套前兆仪器数据异常监控系统。这套系统在功能上不仅要实现监控仪器的网络连接异常,同时能够对前兆数据进行分析,实时捕获仪器的数据异常信息。系统首先采用动态web页面数据采集技术来实现一套安全可靠的实时数据接口,在此基础上,系统提供一个数据异常判定规则的设计模块,该模块提供了两类异常判定规则的设计方法。观测员可以根据自己的需要来动态添加异常判定规则,这些规则载入系统后,系统启用该规则对前兆时间序列采用滑动窗口技术进行实时检测。从而实时捕获仪器故障导致的数据异常信息和符合用户兴趣点的异常信息。
Combined with long-term equipment maintenance practice of seismic station and on the basis of the analysis of the common Precursor instrument malfunction, this paper puts forward to design a set of system on the abnormal monitoring of precursor instrument data in view of the present monitoring. Not only does this set of system want to achieve the monitoring of equipment abnormal network in function, but also it want to analyze the precursory data and capture the instrument information of anomaly data real-time. Firstly, the system adopt the acquisition technology of dynamic web page data to achieve a reliable real-time data interface, on this basis, the system provides a design module of the rule on the judgment of anomaly data, the module provides two types of its design methods. According to their own needs, the observer can dynamic add the rules of abnormal judging, when these rides load into the system, the system enable the rule to real-time monitor on the premonitory time series by using a sliding window technique. Finally, it can real-time capture the anomalous data information caused by the fault instruments and the anomalous information in accordance with the user＇s interested points.
