摘要
本文介绍采用多台MCS—51单片机作为从机与一台AST PC主机构成的主从式系统.利用从机与主机的串行通讯,使所有从机的数据汇集到主机集中处理,可打印成报表或编制成数据库文件以便传送.本系统目前用于集中式多路电话计费.但也可扩展A/D,D/A,并行接口等用于其它适合主从多机系统的数据采集与控制.
In this study, we introduced the system of principl and secondary form.in it we used more than one platform MCS-51 monolithic computers to do secondary computers and one platform AST PC principal computer to constitute it. We utilized the serial communication of secondary computers and principal computer,lct all data in secondary computers gather in principle computer to process,and reported tables may printed up or the documents in data bank also organized up for the convenience of tansmission.Currently, we count expenditure with subset's normal multiplex telephone in this sys-tem.But may yet expanded A/D.D / A.parallel mouthpiece etc to used for data acquisition and control on other suitable system of principal and secondary multicomputer.
