摘　　要：数据采集存储系统具有广泛的应用,在进行高速采集等需要将数据进行先存储后传输的场合中,系统数据的高速可靠存储能力是制约系统速度与可靠性的主要因素之一。它要求系统在短时间内能够可靠存储大容量的采集结果。针对一些特殊研究和生产场合的高速数据流无丢失大容量存储的要求,设计了基于FPGA的多通道多速率混合测试存储系统。为了保证多通道数据的高速可靠存储,系统综合采用编码多通道数据、高速数据流乒乓传输、带快速坏块检测的Flash存储等手段。仿真表明采用该存储方案可以保证高速数据流无丢失大容量存储。Data acquisition and storage system is widely used in many areas. The ability of high-speed and reliable storage is one of the key factors in situations where the data should be saved before transmission. The high-speed data acquisition system requires much data to be saved reliably in short time. Multichannel and multi-rate hybrid data acquisition and storage system based on FPGA is introduced to aim at satisfying the needs of high-speed and reliable storage in special research and production situations. In order to ensure that the multichannel data to be saved reliably and quickly, multichannel data coding and ping-pong buffer and bad block check are used in the storage system. Simulation presents that high-speed and reliable storage can be realized bv the solution.
