DQK—1型磁变仪倾斜仪监控器
|
摘要
70年代的仪器设备受当时的技术和材料的限制 ,存在着多种弊端。提高观测精度 ,改善内在质量问题势在必行。本文从前兆台网的实际出发 ,把地球物理与电子技术相结合 ,把维修经验与仪器研制相结合 ,运用功率电子学和自动控制理论 ,试制成功“DQK— 1型磁变仪倾斜仪监控器” ,把地磁、地倾斜等前兆观测项目中的每天 3次人工检查仪器改为实时监控 ,为确保地震前兆观测的可靠性和连续性提供了硬件保障。
Electronic technology has been developing rapidly. The instrument made in 1970s had many shortages due to limitation of technology and material. The departments in charge of seismic monitoring pay attentions to raise observation precision and improve data quality. DQK-1 Type monitor controlling variometer and tiltmeter is successfully made by combining geophysics and electronics, maintenance and instrument manufacture, power electronics and automatic control theory. The 3 time checks to precursory observations have been changed into real time monitoring, which provides strong guarantee to the reliability and continuity.
