基于SCSI存储设备的高速数据采集记录仪

A High Speed Data Acquisition and Recording Instrument Based on SCSI Storage Device

介绍了一种通用的高速数据采集记录仪。该系统采用微控制器控制，由A／D转换、数据缓存和SC-SI存储设备（光盘、磁盘）等单元组成。利用高速磁盘，可以2．5Mbit／s的数据传输车连续实时记录9GB而无数据丢失。系统接口采用了现场可编程门阵列FPGA技术，具有良好的柔性和可扩展性，适合于多种高速大容量数据实时采集记录场合。

A high speed data acquisihon and recording in-strument for grneral purpose is presented. It is consisted ofA/D convertor. data buffer and SCSI storagr device and iscontrolled by a whcrocontrollor. As using a high speed SCSImagnehc disk up to 9GB data can be recorded wtth an ex-cellent integrity at a data transfer rate abeut 2. 5Mbit/s.Flexibility and expendability have been guined with fieldprogrammable gute array (FPGA) technique in the designof interface. This instrument can be used in various highspeed real hme mass data acquisition and recording.
