摘要

简单介绍程控步进测控技术及其在DSG型(CCD)水平变形测量仪中的应用以及现场自动化标定的实现过程。给出了观测仪器在北京牛口峪地震台的实际应用与现场标定结果:现场标定结果表明:由于在仪器标定系统中引用了步进电机程控技术,明显地提高了仪器标定装置的技术含量,同时也提高了标定精度,克服了在仪器标定中人为因素的影响。在提高仪器的技术指标的基础上,首次实现了断层形变类观测仪器自动化标定的功能。
In this paper the program-controlled step technique and the DSG horizontal deformation measuring apparatus are introduced,and the procedure of in situ calibration is discussed.The practical application and calibration results of measuring apparatus at Niukouyu seismic station of Beijing Earthquake Administration are presented.The calibration results indicate that the application of program-controlled step technique in the automatic calibration system increased significantly the calibration accuracy of fault deformation measuring apparatus and supressed the artificial influencing factors.The automatic calibration of fault deformation measuring apparatus has been implemented under guarantee of meeting instrument technical specifications.
