摘要
利用地震前兆数据跟踪分析平台,搜集并梳理全国定点形变观测台SS-Y型伸缩仪2016—2018年数据跟踪分析观测系统事件记录、观测日志,按影响因素分类,归纳为前置放大器、传感器、主机、供电、传输线路、避雷器、标定装置等13种故障类型,分析各故障类型中发生的曲线特征与技术解决措施,为基层台站伸缩仪观测日常运维中快速锁定故障位置提供参考,进一步提高观测数据的完整性、连续性,提高数据跟踪分析工作的实际效能。
Using the tracking analysis platform of precursory observation data,this paper collects and analyses events,atlas,and observation logs of SS-Y extensometers at fixed deformation observation stations from 2016 to 2018,and summarizes 13 types of faults according to the influencing factors.Among them,the modules with main faults are preamplifier,sensor,host,power supply,and transmission line.In order to provide experience and reference for daily operation and maintenance of extensometers at stations on how to quickly and accurately determine the location of faults,further improve the integrity of observation data,and provide guarantee for the application of observation data,this paper summarizes and analyses the image characteristics and technical solutions of fault curves in each module,such as lightning arresters,calibration devices,etc.
