摘　　要：针对地震记录仪中数据存储容量受限的问题,提出了基于USB(Un iversal Serial Bus)接口模块移动介质作存储设备,实现了地震记录仪对天然地震波的长时间记录。存储容量从16 Mbyte扩大到2 Gbyte,同时USB接口模块作为中介对移动存储介质进行操作,使数据存储更有效、可靠。数据以文件格式存储有利于数据回收、处理。大大降低和简化了操作人员的工作量。Removable storage medium based on USB （Universal Serial Bus） interface technology has been put forward to solve the problem that seismic recorder has limited storage capability. Using this kind of design seismic recorder can work in logging nature seism wave and can be used in this instance where hypocenter is manpower. Storage capability is enlarged from 16 Mbyte to 2 Gbyte, at the same time, the methods of using USB in terface module to write storage equipment are more effectual and steady. The finally data are storaged in file styleand can be read by computer easily, which predigests operator＇s workload greatly.
