摘要

设计并实现了一套国产海上工程地震勘探系统.该系统采样精度为24位,最高采样率为54kSps.系统采用分布式架构设计,数据的采集、传输、处理和同步完全采用硬件设计,使得该系统具有结构简单、易于扩展和维护的特点.在16kSps采样率下,该系统支持单缆最大96通道,并支持到多缆的扩展.该系统不但可应用在高精度工程地质勘探上,而且可应用于其他分布式远程多通道的模拟信号采集领域.
A system of domestic marine seismic exploration was designed and realized.The sample precision of the system is 24 bits,and the maximum sampling rate is 54 kSps.The main characteristics of the system are distributed architecture and hardware design for data collection,transmission,processing and synchronization.The system has the attributes of flexible configuration,stability and structure simplicity.In the sampling rate of 16 kSps,the system supports single cables of 96 channels,and supports the extension to multiple cables.Besides high precision engineering geological exploration,the system can be applied to other distributed remote multi-channel analog data acquisition fields.
