基于PLC与计算机RS-232通信的扩展应用

Expansion Application of Computer RS-232 Communication Based on PLC

文章介绍了一个科普展品的设计实施方案,给出了PLC电路及程序,并用VB程序实现了在计算机上对RS-232通信数据的发送和接收,以及实现多媒体的调用,观众可以和展项互动。(注:本展项为我单位在广东科学中心F展区人与健康展馆B09展项《食物之旅》的实施情况)。

This thesis will introduce a practical application scheme of exhibition project, including its PLC circuit and program. Besides VB program is realized in sending and receiving the RS-232 communication data in the computer, as well as transferring the multimedia, so that the audience and the exhibition items can be mutual reacted. （ Remark： this exhibition is a practical application project contracted by my company in the Guangdong Science Center human being and health B09 《Food Travel》 of F exhibition section）.
