摘要
主要介绍利用Delphi和AT89C2051单片机开发的会议表决系统,该系统通过RS485总线实现单片机与单片机、单片机与PC机的通讯,并在PC机上对数据进行统计、分析、存储与打印,实现了开会表决评分自动化,节省了工作时间,提高了工作效率。
The conference auto-voting system is introduced, which is developed with the help of Delphi and AT89C2051 SCM technology. By using RS485 Bus, SCM-to-SCM and SCM-to-PC communication can be realized. In addition, corresponding data can also be processed, analyzed, saved and printed, and hence achieve the automatization of conference voting and grading, which results in time-saving and high-efficiency.
