摘要
介绍了将软、硬件“看门狗”技术、软件陷阱及TL7705CP芯片用于工控机系统，构成一种有效的系统恢复技术的电路设计方法，并研究了电源干扰下RAM数据的动态保护问题，同时给出了实际电路和程序结构。
The paper introduces a circuit design method which applies software and hardware watchdog technology, software trap and TL77O5CP chip to system of industry control computers to form a effective system recovery technics and studies the problem of dynamic protecting RAM data in supply voltage jamming, while presents a few practice circuits and two flow charts.
