【摘要】 传统的ＤＤＥ在批量数据变量交换方面存在着一些缺陷。本文提出采用成组传送ＤＤＥ的方式交换数据变量,利用成组传送ＤＤＥ提供的动态链接库接口开发应用程序,极大的节省了系统资源,加速了变量交换。这种方法在沥青拌合楼控制系统的开发中得到了很好的应用。更多还原

【Abstract】 There are some defects when DDE is applied to exchange variables in scores. In this paper, BlockDDE is proposed to overcome these defects. Some interfaces of BlockDDE are used to develop application. It can save system resources and accelerate exchange of variables to use BlockDDE. This method is applied in forced-mixing asphalt plant’s control system and works well.更多还原
