摘要
通讯技术是地震数据采集工作中的关键技术之一,直接影响着采集系统规模的大小与工作效率的高低.按照采集工作中应用的通讯技术不同,目前陆上地震数据采集系统分为三类:有线地震数据采集系统、无线地震数据采集系统、混合式地震数据采集系统.文章在三类系统中选择7种具有代表性的产品,对比这7种产品所使用的组网方式、通讯协议及其在通讯方面的性能,分析目前陆上地震数据采集系统中常用的通讯技术的优点与不足,并由此总结了当前陆上地震数据采集工作对通讯技术的需求,提出在陆上地震数据采集中应用一种基于簇树结构的复用传输技术的想法.
Communication technology is one of the key technologies of seismic data acquisition,which directly affects the scale and the efficiency of seismic data acquisition. Currently, land seismic acquisition systems are divided into three types： cabled seismic data acquisition system,wireless seismic data acquisition system and hybrid seismic data acquisition system, according to the communication technology used in the acquisition work. In this paper,seven typical seismic instruments are chosen from the three systems to analyze the advantages and shortcomings of common communication technologies used in current land seismic data acquisition system by comparing their communication architectures,communication protocols and effects in communication,in order to summarize what the ideal communication mode would be,whose aim is to meet the demand of land seismic acquisition system＇s communication. At the end of this paper,a communication method in seismic data acquisition,which is based on cluster-tree structure and multiplexing transmission technology,is prompted.
