摘　　要：在对已有单向传输系统研究的基础上,针对当前单向传输系统的单通道失效、传输速率不高、不存在与用户的交互等弊端并根据用户对可靠高速准实时甚至实时传输的需求,提出了一种基于现场可编程门阵列的多通道高可靠高速单向传输系统并予以实现。该系统从安全性、可靠性、高速性进行设计,通过引入多通道冗余传输、万兆光纤等技术克服了当前单向传输系统存在的单通道失效、传输速度低等问题,从用户角度增加了一些人机交互设计并为后期扩展开发预留了空间。通过测试,该系统能在120 MB/s的速率下稳定运行,单通道失效情况下系统可照常运行。The current one-way transmission system exists the problems of single channel failure, low-speed and no human-computer interaction. A reliable high-speed quasi-real-time or real-time transmission system was needed. Concerning these problems, a multi-channel high-reliability and high-speed one-way transmission system based on Field-Programmable Gate Array（ FPGA） was proposed and implemented for the shortcomings of the current one-way transmission system and the users＇ requirements. This system was designed from the view of safety, reliability and high-speed, which overcame the problems of single channel failure, low-speed by using multi-channel, 10 gigabit fiber and so on. Besides, it added humancomputer interaction design and reserved for the late expansion of development. By testing, the system can run stably at a speed of 120 MB/s, and run as usual when a channel is invalid.
