高速、大容量遥感遥测数据记录与分析系统

High Speed and Huge Storage Capacity Recording System of Remote Sensing and Telemetry Data

介绍一种基于 SCSI磁盘的高速、大容量卫星数据实时记录与分析系统 ,详细分析系统的设计思想、工作原理、系统性能指标测试和应用情况。该系统可将转输速率最高可达 4 0 0 Mbps的遥感遥测数据直接记录到磁盘中 ,不经过计算机的操作系统及数据总线 ,有效地解决了高速持续数据流磁盘记录的瓶颈问题。系统最大存储量可达 1TB以上 。

A kind of real-time recording and analyzing system of high speed and huge storage capacity based on SCSI hard disk is introduced.The design idea,the operation principle,the testing result of the performance and the application of the system are anayzed in detail.The system can record remote sensing and telemetry data at the data rate of 400Mbps and does not base on the operating system and the data bus of computer.It solves the bottleneck of the high data rate sustained data stream recording effectively.The storage capacity of 1TB can be arrived with this system and the recorded data in the SCSI can be post processed.
