海底地震数据记录器
|
摘要
海底地震数据记录器是一种大动态、宽频带数字仪器 ,能用于海底或陆地边远地区记录地震数据 .它体积小、重量轻、操作简单 ,采用两个缓存存储器控制PC 10 4嵌入式计算机 ,能在低功耗、长时间连续记录地震数据 .记录器的关键部件是PC 10 4嵌入式计算机 ,能保证记录器工作可靠 .它使用硬盘存储数据 ,2GB的硬盘能容纳1 9998GB的地震数据 ,记录地震数据多长时间由抽样率决定 .
An ocean bottom seismic data recorder is introduced in this paper. The recoder a broad-band digital instrument of large dynamic range, and can be used for recording earthquake data on the ocean bottom or in remote land areas. It is a compact, light-weight and easy to operate instrument, adopting two buffer memories to control the embedded PC/104 computer, so that it can record the seismic data continuously over long time at a low-power dissipation. The key component of the recorder is the embedded PC/104 computer, which ensures the reliable operation of the recorder, the average power consumption is about 2W. The 2 GB hard disk can hold 1.9998GB seismic datas, the time duration of recording depends on the sampling rate.
