MCS—51通用机是以8031单片机为系统核心,具有显示、微打印、音频盒带信息转贮装入功能.为扩大 MCS—51通用机的多机联用,需在各台用户机内增设共享存贮器.共享存贮器应在结构上与本机相连,同时也可以供其它用户机存取,以实现总体任务分机完成,便于用户在短时间低成本情况下,完成产品调试或系统控制.本文介绍以8031单片机为核心的软/硬件多机共享通讯系统.该系统资源共享是在三台用户机间距离100m 情况下调试的,只要用户机在系统状态下,任何一台机都可争做调用机,完成资源共享,通讯结束后,各机进入串行通讯提示符,接系统键又进入本机系统控制状态.本系统通过按键可灵活完成控制本机工作或共享通讯.
MCS-51 general-purpose machine is based on 8031 single-chip microcomputer as the system core, with display, micro-printing, audio cassette with information transfer loading function .In order to expand MCS-51 common machine multi-machine use, Memory shared storage should be structurally connected with the machine, but also for other user machine access, in order to achieve the overall task of extension is completed, allowing users to complete product debugging or system control in a short time under low cost This article describes the software / hardware multi-machine shared communication system with 8031 single-chip microcomputer as the core. The system resource sharing is debugged when the distance between the three user machines is 100m. As long as the user machine is in the system state, As a calling machine, to complete the sharing of resources, after the end of communication, the machine into the serial communication prompt, then the system key and enter the local system control state.This system can be flexible through the keys to control the local work or share communication.
