【摘要】 介绍采用一台工业PC机与多台单片机通信组成集散控制系统的方法。单片机作为下位机，完成对现场控制参数的采集并发出控制信号；PC机作为上位机，完成各种复杂算法的运算并将运算结果传送给下位机。此种控制方式充分利用了PC机与单片机的优势，对多台退火炉的集中温度控制是非常适用的。更多还原

【Abstract】 This paper introduces using a PC and many monolithic microcomputer communication toform a concentrical and discrete control system. The monolithic microcomputers work as the downcomputers for sampling and sending control signals. The PC is the up computer to take care of com-plex computation,the result of which is communicated to down computers. This control method is veryuseful for some factories in which there are many stoves.更多还原
