摘要

文章介绍一种应用现代高新技术设计的“无大线、无电台、无主机”的新型地震勘探设备。该设备集采集、记录于一体,采用定时、触发、连续等多种采集方式,结合GPS时钟同步技术,实现地震数据的现场存储、定期整体回收数据和后期处理。排列布置灵活、方便,功耗低,记录时间长,解决了复杂工区的勘探问题。同时,由于数据的现场监视问题,它也是对目前传统勘探方法的一种挑战。本文详细论述了这种新仪器的设计思想、工作方法和工作原理。
This paper describes the new generation seismic exploration equipment which is without radio, cable and central recording system. It adopts three acquisition mode of timing, triggering and continuing. It synchronizes all distributed recording units through GPS clock. The equipment has the ability of data acquisition, recording and processing, which fulfill the seismic data field storage, whole collection and post-processing. This system has widespread adaptability, high intelligence, low power consumption, long recording time and is suit to be used in complex region exploration. The design thoughts, working method and principle are listed in this paper.
