| 摘 要： | 针对Internet遥操作中的变时延问题，介绍现有的解决方法，并在分析目前普遍采用的单TCP连接控制方式局限性的基础上，提出基于多连接的时延控制方案。该方法避免了单连接控制方式产生的时延连锁累积问题，能在一定程度上减小平均时延和最大时延，并能保证其在一定范围内平稳波动。最后，通过控制单向变时延的实验，证明了该方法的有效性和可行性。

| Abstract: | This paper addressed the problem of variable time delay in Internet based teleoperation.The currently existing schemes were introduced firstly.Based on the limits analysis of the single-TCP-join scheme which was used widely currently,a time delay control scheme based on multi-join was proposed.It facilitated to avoid the chain-accumulated time delay stemming from the single-join scheme.To some extent,it could also reduce average and maximal time delay and make it fluctuate smoothly.Finally,via the experiment of controlling one-way variable time delay,the feasibility and effectiveness of the scheme were testified. |
