| 摘 要： | 在保留RZB型电容式分量钻孔应变仪传感器功能不变的前提下，充分吸取了原RZB型电容式多分量钻孔应变仪及其他前兆仪器的优点，对其主机部分进行升级改造，实现了RZB多分量的宽频带响应（采样率提升为秒采样）；采用了低功耗、高稳定性的ARM920T高速处理器内核、固化WinCE操作系统，为仪器的稳定性、连续性提供了技术保障；网络接口板外嵌触摸式显示屏，极大地方便了仪器的参数配置以及现场检修；对原供电方式进行改进，实现了集防雷、供电、充电、交直流切换于一体以及软件的远程更新、软件工作的详细日志查询等功能。通过对新仪器数据分析发现，其连续率得到大幅提升，并记录到分钟采样所记录不到的详细地震波响应过程。

| Abstract: | The mainframe of RZB borehole strainmeters has been upgraded, incorporating the core functions of original RZB borehole strainmeters and the merits of other premonition instruments, while retaining its excellent advantageous functions. The upgrades include: capabilities of responding to wide-band signals in RZB multi-component (sampling rate in second level); stabilization and continuities provided and guaranteed by an embedded low-power dissipation, high-stability and high-speed ARM920T kernel, together with customized WinCE; a touch screen on network board facilitating on-site configuration and maintenance; reinforced lightning-proof power supply and charging auto-adapt with DC/AC switching. The software has also been enhanced, with capabilities of remote upgrades and logging (detailed logs are provided for data tracking, exploring and future analysis). Using the new instrument, data analysis finds that the continuous rate has increased substantially, and the minute details of the sample is less than the recorded seismic response process. |
