一种地震检波器同步触发428XL的方法及应用

A Method and Its Application for 428XL Synchronous Triggering Using Geophone

常规的同步触发通常是仪器提供指令,由编码器、电台与爆炸单元共同完成。而在实际地震采集作业中,通讯、地形以及成型炸药的申请审批等会遇到各种困难。基于此,考察比较了428XL采集系统交叉站的XDEV2接口,探索出一种区别于有线放炮却更简便可靠的同步激发方式,并结合实际作业中的具体问题进行了简要的分析探讨。

Conventional synchronization triggers in seismic acquisition are usually provided by the instrument and are performed by the encoder,the radio,and the explosive unit.However,in the actual seismic acquisition operation,there are various difficulties in communication,terrain,application and approval of explosives,etc.Therefore,by investigating Laux′s XDEV2 interface of 428XL acquisition system,this paper explores a more convenient and reliable way of synchronous excitation different from that in the line source input(LSI).A brief discussion is made combined with practical problems.
