eSeis节点单元存储下载通道电路分析与故障排除

Analysis and troubleshooting of eSeis node unit storage download channel circuit

eSeis节点单元在完成野外地震数据采集后,将设备内的原始数据成功转储,是处理节点数据及清理节点内部存储空间的前置工作,为后续工作的顺利开展提供保证。在实际操作及保障工作中,数据的存储和下载故障占总故障率的25%左右,占比相对较大。因此,梳理和分析存储、下载通道的电路组成是维修保障工作的重要内容。本文详细叙述了eSeis节点单元地震数据的存储和下载通道构成,并给出了此类故障的维修方法。

eSeis node unit successfully dumps the original data in the equipment after completing the field seismic data acquisition,which is the pre-work for data processing and cleaning up the internal storage space of the node and provides an important guarantee for the smooth development of subsequent work.In the actual operation and support,the failure of data storage and download accounts for about 25%of the total failure rate,and the problem is outstanding.Therefore,combing and analyzing the circuit composition of storage and download is an important content in the maintenance and support job.In this paper,the storage and download circuit composition of eSeis node unit are described in detail,and the solutions of this kind of fault are given.
