vxWorks下基于缓冲队列的全双工网络通讯

文章针对半自动大型仪器使用半~K．．T--网络通讯造成的效率下降问题，建立了在嵌入式实时操作系统vxWorks下全双工网络通讯的模式，并特别提出了双缓冲队列的流水线处理方法和通讯死时J"l的概念。该方法充分利用vxWorks对多任务和网络的良好支持，做到了在操作人员层面上的软件零死时间，在改善系统响应特性，提高软件效率上都很有帮助。因此比半双工通讯方式更加适用于半自动控制。

Generally。half duplex net communication method decreases the eficiency of semiautomatic devices．To solve this problem，a mode of full duplex is developed，under the embedded RealTime Operating System vxWorks．Specially，the method 0f pipeline based on multi—bufering queues and the concept of communication dead—time are introduced．This
method makes the best of vxWorks's support on multi—tasks and network programming．It achieves near ~lt'O software
dead—time on ope rational level，improves the response characteristic，an d increases software eficiency．Comparing with half
duplex mod e，it is more applicable to semiautomatic contro1．
