摘要
针对目前工业以及民用领域中许多现场仪表设备管理软件不支持现场总线的现状 ,提出应用虚拟串口软件可以将这些管理软件平滑地移植到新的管理系统中 ,而不要修改原软件。文中首先介绍了虚拟串口软件的概念 ,后而以以太网作为现场总线的例子 ,详细给出了虚拟串口软件的程序结构及接口的设计方法。
To the situation of industry and civil field that many instruments don′t suppo rt device FieldBus, the conclusion is given that using virtual serial communication device can make the manageme nt software to support the FieldBus without modifying anything. The conce pt about virtual serial communication device is introduced first, then the desig n method of structure and interface about virtual serial communication device is discussed in detail.
