摘要
在浅海或内陆水域使用气枪船施工时,为了实现与地震采集仪器的同步触发记录,需要使用GCSLink同步控制器。本文首先介绍了在GCSLink主端(Master)触发气枪放炮、从端(Slave)触发428XL仪器采集时,GCSLink主端与428XL系统的LCI-428不同连接方法;而后根据不同的连接方法分析了GCSLink主端和从端触发方式的同步过程,并绘出了各自的同步时序图,总结了GCSLink主端和从端触发时的关键同步参数;最后介绍了使用GM338电台替换因接收问题而无法使GCSLink主、从端同步的CDM1250原装电台的方法。
In order to realize synchronous triggering with seismic data acquisition system when using air-gun to shoot in a shallow sea or inland water for seismic exploration,GCSLINK equipment is needed to use.Firstly,this paper introduces several different connecting methods between GCSLink when it acts as master trigger with 428XL instrument as slave trigger to shoot.According to the different connection methods,this paper makes detailed analysis about the synchronization process and draws their synchronous timing diagram,thus the key synchronization parameters of master triggering and Slave triggering are deduced.Finally this paper describes how to use the GM338 radio to replace the original CDM1250 radio which cannot enable the GCSLink master-slave synchronization because of its reception problem.
