摘要
为了提高SQ-70D型石英水平摆倾斜仪的观测性能,研究影响倾斜仪性能的主要因素,并从软硬件方面提出倾斜仪升级改造方法,升级后仪器测量精度可达亚像素级、动态范围扩大到14″,应用场合显著扩大;仪器从分钟采样升级为秒级数据采集,满足行业标准要求。本次仪器性能升级易于实现,便于推广。
In order to improve the observation performance of SQ-70 D quartz horizontal pendulum tiltmeter, the main factors affecting the performance of tiltmeter is studied, and the upgrading methods from hardware and software are proposed in this paper. The measurement accuracy of the upgraded tiltmeter can reach sub-pixel level, and the dynamic range can be up to 14″, which significantly expands the application of this instrument. Meanwhile, the tiltmeter can achieve the second-level data acquisition to meet the requirements of industry standards. The upgrading of SQ-70 D tiltmeter is easy to be realized and popularized.
