Abstract: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.
Keywords:SS-Y extensometer  instrument fault  curve feature  fault solution
