【摘要】 数据采集是新型地震数据采集记录系统主机软件的核心组件之一。本文研究并设计了一种海量地震数据实时采集接口,通过实时交互协议的定义和实时交互框架的构建方式,屏蔽了多套地面采集设备的异构性,实现主机软件系统与野外站单元、源控制设备的连接,支持对大道数海量地震数据进行实时、稳定地采集与传输。模拟测试结果表明,其带道能力满足20000道@2ms的要求;野外试验及生产试验表明,其可靠性满足生产要求。更多还原

【Abstract】 Data acquisition unit is one of the core components in the new type of seismic data acquisition recording system.To achieve the software communication with the field station and the source control equipment,and to support the massive seismic data collecting and transmission stably,a massive real-time seismic data acquisition interface is designed and developed in this paper.Through real-time interaction protocol definition and framework to build real-time interactive mode,this interface can shielding the differences among several sets of ground acquisition equipments.Test and experimental results show that the capacities can meet with 20,000 channels @ 2ms requirements and the reliability can also meet the production requirements.更多还原
