多微机联控在大型三面翻广告牌中的应用

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。

Application of Multi-computer Control in Large Three Sides Billboard

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 contro...
