摘要
综合整理2013-2020年的全国形变现场异常核实报告,对其中涉及观测系统方面的故障进行统计及分类研究,按照故障类别可分为7类,即仪器主体故障、电源及信号线故障、数据采集系统故障、前置放大器及格值问题、标定系统故障、耦合问题、仪器墩及仪器底脚问题.在各种仪器故障类型中,以仪器主体故障、电源及信号线故障和仪器格值问题为主.对每类仪器故障给出了详细的实例,结合相关故障造成的数据变化形态进行了分析,并给出了各类故障的建议解决方案.
The anomaly verification reports of deformation from 2013 to 2020 were collected.The observation failures in these reports were statistically analyzed and classified.The failures can be divided into 7 categories,including instrument main failure,power supply and signal line failure,data collector failure,preamplifier and scale value failure,calibration system failure,coupled problem,instrument pier problem,respectively.Among them,the main problems are instrument main failure,power supply and signal line failure and scale value failure.This paper exhibits detailed examples about various observation system types,analyzes data variations caused by kinds of observation system failures,and suggests solutions.
