摘要
为了提高采集数据传输的可靠性,提出了一种基于光链路和被覆线链路互为热备份的采集数据传输系统。系统采用光链路和被覆线链路双冗余传输路径,通过对两种路径传输品质的监测,利用仲裁器自动倒换传输路径。并通过同步缓冲设计,实现了两种传输路径采集数据的同步输出。同时进行了合理的软、硬件设计,实现了数据双冗余链路传输。
In order to improve the reliability of data transmission, this paper presents a hot backup transmission based on optical link and phone link. The system has multiple functions such as： dual redundancy protection link, real-time check and control the channel, switching channel by arbitrating the collection result of two link transmission quality. The collective data of tow transmission channel is output delayed by FIFO. The paper introduces delay synchronous theory, present the hardware and software design in detail.
