摘要
本文介绍了一个专为工矿企业电力自动化调配而设计的ＳＣＡＤＡ系统，给出了由８０Ｃ１９６单片机组成的双ＲＳ一４２２位总线的通信网络方案。并结合８０Ｃ１９６的通信方式，推出了一个抗干扰能力强、码效率高、设计新颖的问答式通信规约。以Ｗｉｎｄｏｗｓ３．１环境为依托，本文还提出了一个多媒体输入输出、多窗口、多任务、结构开放的后台机软件框架。
In this paper,a SCADA system for the automatic dispatch of local power system is presented and the plan ofcommunication network with twin RS-232 bitbus is proposed.COmbined with the multi-processor communicationmode of 80C196 the author developed a brand-new communication protocol of the polling mode, which makes afeature of better capability of interference protection and higher efficiency of the code。On the basis of MicrosoftWindows 3.1 environment,a software frame of the back-end computer with multi-media I/O,multi-window,andmulti-task is also proposed。
