摘要
通过对基于RS-485总线多主通信原理的分析,提出了基于RS-485总线多路抢答系统的实现方法,给出了抢答系统的硬件实现和抢答器软件流程图。经性能测试,系统具有安装方便,操作简单,性能可靠等优点,能满足多路抢答系统要求。
Through analyzing the principles of multiple master communication based on RS-485 bus, a multiway quiz game system based on RS-485 is suggested along with its hardware schematics and software flowcharts. Testing has shown that the system can be conveniently implemented and it has the merits of easy operation and reliabiltiy as well, which meets the requirements of a multiway quiz game system.
