| 摘 要： | "十五"建设的ELF台站均敷设ACF-4M型电磁仪,记录到多次地震前后的电磁异常变化,但该仪器没有实现自动化。本文介绍ELF仪器的远程控制和数据传输以及原始数据转换的研制方案。由于ELF记录仪无法接入因特网,要远程触发ELF仪器必须有中间设备,首先远端计算机通过互联网控制局域网计算终端,通过局域网计算终端运行SM27.exe工作程序来触发并通过相应程序实现数据的传输;将ELF记录仪采集到的时间序列信号(*.SBF数据格式)、仪器本身的参数信息和采集状态信息依据其编码规则转换成通用的数据格式导出,将计算的功率谱、阻抗、阻抗相位文件以优势频率或任意频率形成时间序列文件进行分析,提高ELF观测资料的应用效率,加快观测电磁数据的使用效率。

| Abstract: | A great number of electromagnetic abnormal phenomenon before or after earthquakes were recorded by electromagnetic instruments ACF-4M.These instruments have been installed at ELF (extremely low frequency) stations built in the 10th "Five-year Plan" period.With the development of urbanization, many observation sites cannot meet the requirements of electromagnetic observations; therefore, unattended stations with low electromagnetic background noise are needed.However, the measurement system did not achieve the required automation.This study introduces the remote control and data transmission of ELF instruments and the development plan of the original data transformation.As the ELF recorder cannot access the Internet, it is necessary to have intermediate equipment to remotely trigger the ELF instrument.The remote computer controls the local area network''s computing terminal through the Internet, and subsequently through the terminal corresponding programs run to realize data transmission.The ELF instrument can improve the application efficiency of observation data and speed up the use efficiency of electromagnetic data. |
