摘要
SCSI(小型计算机接口)被广泛地应用于各种智能化设备之中。本文详细介绍了SCSl的构成、SCSI总线上信号的传送方式以及SCSI操作的8个阶段,并以Opseis Eagle、SN388和I/O system Ⅱ三种地震数据采集系统为例,说明了SCSI在遥测地震仪器中作为专用的外设接口所起到的必不可少的桥梁作用。
SCSI (small computer system interface) is wide used in different intelligent internal. This paper made a detailed introduction about the component parts of SCSI, the transmission ways about signal with eight steps of SCSI. Moreover, this paper analyses three kinds of seismic data acquisition systems (OPSEIS EA-GLE system, SN388, SYSTEM I ) to show SCSI is indispensable in the special interface of peripheral e-quipment for telemetry seismic instruments.
