摘　　要：根据计算机-多单片机系统的多级分层结构,采用异步串行多机通信和主从呼叫响应的通信模式,对表决通信软件的系统功能进行规划。选择和约定了通信模式、通信协议。对下位机通信软件、上位机通信软件和上下位机间的通信过程进行了设计。引入了多机通信的差错控制。系统构建的多机网络模型和上下位机软件模块具有一定的借鉴价值。According to the multi-level hierarchy of computer and multi-SCM system, using the communication mode of asynchronous serial multi-machine communication and maste^slave call response, the paper plans the system functions of the voting communication soft ware, selects the communication mode and agrees to the communication protocol. The paper designs the communication software of the slave computer and the host computer, explains their communication process, and introduces the error control of multi-machine communication. The muhi-machine system network model and the host and slave computer software module being constructed have some reference value for the related applications.
