大型电子投票表决系统通信协议的设计与实现

根据通信协议的分层结构，对物理层、数据链路层和应用层进行设计。实现了下位机（主控制器、分支控制器和表决器）的通信协议和上位机（计算机）的通信协议。该协议适用于计算机和单片机点对点通信的情况。本文所提出的通信协议的设计思想和思路方法对于相关设计和应用具有一定的参考意义和借鉴价值。

Design and Implementation of Communication Protocol with Large-scale Electronic Voting System

In terms of the hierarchy of the communication protocol, the author designs the protocol of physical layer, data link layer and application layer. The paper achieves the communication protocol of the slave computer (the main controller, the branch controllers and the voting machines) and the host computer (the personal computer). The protocol applies to the case of the personal computer and the case of point-to-point communication between multi-single-chip-microcomputer. The proposed design methods and ideas have a certain significance and reference value for the related designs and applications.
