由于1553B总线的传输速率限制,直接进行图像、声音、定位导航等大数据信息传输,将会导致其他紧急消息传输时延过长。针对这一问题,提出了一种基于1553B总线的信息传输调度策略。该策略的控制思想是在对同步信息进行负载均衡调度的基础上,对大数据信息进行动态分解插入,实现了在不影响紧急消息的前提下大数据信息在1553B总线中的实时可靠传输。实验结果证明了该传输控制策略的有效性与可行性。
Due to the limitation of the transmission speed of the 1553B bus, direct transmission of big data such as video, audio, positioning and navigation will lead to long delay of other emergency message transmission. In response to this problem, a 1553B bus based information transmission scheduling strategy is proposed. The control idea of this strategy is to dynamically decompose and insert big data information on the basis of load balancing scheduling of synchronization information, so that the real-time and reliable transmission of big data information in the 1553B bus can be realized without affecting the emergency message. The experimental results show the effectiveness and feasibility of the transmission control strategy.
