摘　　要：单片机测控系统往往运行在较恶劣的环境中,各种干扰不可避免入侵计算机系统。笔者经多年的现场实践,从软件抗干扰的角度,总结了用数字滤波、软件拦截、软件自恢复、软件看门狗、软件重复操作5点技术措施,能有效地弥补硬件抗干扰的不足,提高系统运行的可靠性。SCM monitoring system generally runs in a rather fierce environment, as a result, various interferences would unavoidably invade into the computer system. After years of field practice, author has concluded 5 technical measures based on software anti-interference, which includes digital filtering, software intercepting, software recovering, software watchdog and software repeatedly operating. All these measures can effectively make up some hardware anti-interference shortages and improve the system operation reliability.
