摘要
提出了一种基于小型计算机系统接口SCSI总线的可实现数据高速、持续传输的数据通道设计方案.该方案以SCSI协议控制器FAS660为基础,用大容量的SCSI硬盘作为记录介质,由局部CPU来执行存储通道的实时控制等功能.为了便于数据的管理和组织,进一步提高数据的记录效率,以FAT32文件系统为基础,给出了适合高速数据采集的文件格式,该文件格式兼顾了自定义记录格式和直接采用通用文件格式的特点,可满足数据高速采集的实际需要.
In data acquisition system, the data storage channel based on PCI （Peripheral Component Interconnect） bus can not satisfy the increasing demand of real-time. Owing to this, SCSI （Small Computer System Interface） bus-based design scheme for data channel rapid realizing and continuous data transmission was proposed which comprised SCSI controller FAS660 and SCSI hard disk with large capacity and local CPU. A file format suitable for collecting data with high speed was given on the basis of FAT32 file system, to manage and organize data, and improve the efficiency of recording data. The common characteristics of FAT32 file system and custom-record file format were both taken into consideration in the file format, meeting the real-time demand of data acquisition system.
