摘　　要：多微机联控系统应用不同类型的单片机,构成一个主控制器和多个现场控制器,充分发挥不同类型单片机的长处以提高系统的实用性和性价比。主控制器和多个现场控制器之间采用异步串口通信或"软串口"按照"通信协议"实现分支通信,组成多微机联控的"集散式控制"系统,按三面翻牌面翻转的控制要求分段驱动电机,实现大型三面翻牌面的定画面、定时间、可选翻转方式、出错牌面的"自动纠错翻转"等驱动要求。多微机联控系统极大地简化了控制电路的连线,简化了电气控制安装工艺与施工,在降低工程费用和后期维修费用的同时,可大幅提高控制系统工程的可靠性、稳定性、性价比。Multi-microcomputer control system in conjunction with different types of single-chip constitutes a host controller and multiple site controllers. It can give full play to the advantages of different types of single-chip so as to enhance system＇s practicality and cost-effectiveness. The branch communications between host controller and multiple site controllers is realized using asynchronous serial communication, or ＂soft-serial＂ in accordance with the ＂communication protocols＂, so that a multi-microcomputer controlled ＂Distributed Control＂ system is composed. According to the control requirement of three flop flip sides, the motors are driven section by section to achieve the driving requirements of large three sides bill board for picture, time, optional flip ways, and the ＂automatic error correction flip＂ for error face and drive the requirements. The multi- microcomputer controlled system can greatly simplifies the connection of the control circuit, the installation and construction of electric control, and significantly enhances the reliability, stability, and cost-effectiveness of the control system engineering, while reducing the engineering cost and later maintenance cost.
