摘　　要：随着计算机控制技术的不断发展,单片机的应用不断走向深入,而单片机控制系统往往运行在恶劣的环境中,各种干扰不可避免地侵入控制系统.通过对硬件和软件抗干扰的设计,特别强调软件系统可靠性设计,避免或减少单片机系统死机,以确保系统可靠工作.With the development of the computers control technology,the application of the Microprocessor control unit（MCU） is moving towards deepening constantly and MCU control generally runs in a rather fierce environment,as a result various interferences would unavoidably into the control system.The anti-interference hardware and software system was designed and the reliability design of software system was emphasized in order to avoid or reduce breakdowns of the MCU system and ensure the reliable operation of the system.
