摘　　要：介绍了一种基于LVDS的高速远程图像数据存储系统。系统以FPGA芯片作为控制核心,采用低压差分信号技术(Low voltage differential signaling,LVDS)接口解串和驱动芯片相结合,保证了有效接收远程数据;采用交替双平面的FLASH编程方式来控制图像数据的存储,实现了以28.95MB/s的速度对实时图像数据进行存储的要求。经试验验证和实测证明,该图像数据存储系统性能稳定,数据存储可靠,能满足实际测试要求。Due to the characteristics of large amount of data and high rate of transmission in a system of remote image acquisition, a remote image storage system based on low voltage dif- ferential signaling（LVDS） is introduced. The FPGA is designed as the core, and the LVDS in- terface solution string and the drive chip are combined, thus ensuring the effectiveness of re- ceiving remote data. Meanwhile, the alternative two-plane FLASH programming method is a- dopted to storage the image data. It achieves the speed of 28.95 MB/s for storage of real-time image data. Experiments prove that the data storage system is stable and reliable and it can meet practical requirements.
