| 摘 要： | 流动观测台网与固定观测台网的结合是当前地震观测技术系统发展的一个趋势. 针对流动观测时地震计与地震数据采集器互相独立、 携带不方便、 功耗高的问题， 自主研发了一款适合流动观测的集地震信号提取、 数据采集、 记录和服务为一体的数字地震仪. 该仪器具有频带宽(60 s—80 Hz)、 动态范围高(>140 dB)、 功耗低(0.6 W)、 携带方便(整机重量在15 kg左右， 包括供电系统、 GPS天线和包装箱)等特点. 详细介绍了该地震仪的外观结构、 整体硬件结构、 低功耗处理技术和所采用的灵敏度校正、 标准方位和正交校正技术. 对仪器的主要性能参数指标进行了严格的测试， 并给出了具体的测试结果. 该仪器研制完成后， 投入到了青海玉树MS7.1地震震后流动观测中. 从半年的实际使用结果来看， 该仪器能够满足流动观测的要求.

| Abstract: | Combination of mobile and fixed network observations is one development tendency of current seismic observation system. In order to solve the problems such as mutual independence between seismometers and seismic data acquisition instruments, inconvenient portability and high power consumption in mobile observation, this study develops a new low-power broadband sensor-integrated data logger, which contains a three-component seismometer, a data acquisition unit, a recording device and services. The instrument has a wide frequency bandwidth (60 s—80 Hz), high dynamic range (>140 dB) and low-power consumption (0.6 W), and is easy to carry. Whole weight of the instrument is about 15 kg, including the power supply system, GPS antenna and crates. This paper describes its apparant structure, hardware structure, low-power processing techniques, sensitivity correction, standard orientation and the orthogonal correction technique in detail. We have rigorously tested the main performance parameters of the instrument and given the specific test results. After the development of instrument was completed, we put it into mobile observation after the 2010 Yushu MS7.1 earthquake. The test results show that this instrument can meet the requirements of mobile observation. |
