| 摘 要： | 为了提高DCS系统数据传输效率与可靠性,提出该系统应采用基于以低功耗、高性能的ARM控制器为主控的分散处理单元(DPU),另外在软件设计方面,要通过避免复杂的窗口算法,提高系统通讯效率.该系统软件设计在协议栈中共创建了网卡接收、TCP、UDP三个任务.TCP任务优先级最高,三者通过操作系统提供的功能,实现任务之间的切换...

| Abstract: | In order to enhance the transmission efficiency and reliability of DCS data transmission,this paper proposes to adopt the Distributed Processing Unit(DPU) based on the ARM controller with low power consumption and high performance as the main controller and points out that the complicated Sliding Window Algorithm should be avoided to enhance communication rate from the aspect of software design.This system software design creates network connection,TCP and UDP,among which the priority of TCP is the highest.... |
