proteus双机仿真系统-电子发烧友网

1）两个单片机系统分别作为服务器和答题终端。服务器负责验正考生个人信息，发送试愿到降端，定时收卷及判分功能。答题终端负责输入考生个人信息，答题，修改答案及传送答案到服务器。
2）服务器验证考生个人信息，若信息不正确则向终端发出提示信息。信息验证正确后将试题发送到答题终端，同时开始计时。无论答题是否完成。考试时间到则强制收题。也可在考试时同尚有剩余时接收答题终端发送过来的答案。收题后进行判分工作并给出最终得分及答题情况统计信息。对回答错误的题日则给出原题及正确答案。
3）答题终端在收到试题后向考生显示试题内容（可逐道显示）并接受考生输入的答案。试题显示应具备翻页功能以允许考生反复浏览试题或检查所作答案。当考生检查完毕且考试时间尚有剩余，允许考生向服务器发送最终答案。
4）实现服务器和答题终端的两个单片机系统均应包含键盘和LCD液品显示模块。两个单片机系统通过串口进行通信。
*************************************************
（1）给出使用说明，包括按键的定义，操作方法等。
（2）所有功能用途均可实现且各功能转换正常（模拟5道题即可）。
（3）考生个人信息包括考生姓名（可用拼音表示）和6位的学号。
（4）验收时需要演示考生个人信息不正确时的处理情况：
（5）服务器和终端都应实时显示考试剩余时间：
（6）四则运算应覆盖加减乘除四种运算：
（7）终端答题时，在未提交答案前应允许反复浏览或修改答案
