对一个微机控制系统而言,如何有效地抑制干扰是首要问题。为此,本文介绍了一种由8031单片机为核心的控制系统自启动电路,它可以及时地克服由于干扰而产生的微机控制系统的死循环、程序“跑飞”等“死机”现象,使微机自动复位,从而保证系统正常运行。
For a microcomputer control system, how to effectively suppress interference is the most important issue. To this end, this paper introduces a self-starting circuit of the control system with 8031 single-chip microcomputer as its core, which can timely overcome the dead-cycle of the microcomputer control system caused by the interference and cause “hang-off” Automatic reset, thus ensuring the normal operation of the system.
