摘　　要：为了提高微机系统的测控精度及稳定性,提出微机控制系统的抗干扰设计方法。详细介绍了微机控制系统的软、硬件抗干扰设计措施,硬件抗干扰措施主要包括电源系统抗干扰、I/O接口抗干扰等几部分,软件抗干扰措施包括指令冗余、软件陷阱和软件滤波等。同时,将一些抗干扰措施应用于卷烟机烟支重量控制系统中,实验结果表明,这些措施是有效的,能够较好地消除和抑制进入烟支重量控制系统的干扰信号。To improve the precision and stability of measurement and control in microcomputer system,the anti?interfe?rence design method of microcomputer control system is presented. Software and hardware anti?interference measures of micro?computer system are introduced in detail. Hardware anti?interference measures include power system anti?interference,I/O inter?face anti?interference and other circuits. Software anti?interference measures include instruction redundancy,software trap and software filtering. Some anti?interference measures are applied in cigarette weight control system of cigarette making machine. The experimental results show that these measures are effective,and can eliminate and restrain interference signals entered into cigarette weight control system effectively.
