摘要：介绍一种用休眠恢复方式使单片机正常运行的方法，提高抗干扰能力的方法；分析其适用范围，提供和使用的电路concretly，结合实例，分析这些特点，这种运作方式的硬件和软件设计。

关键词：单片机从休眠还原到可运行的过程方法。简介：随着在微电子技术的飞速发展，在一个性能迅速提高电子时代，在运行中表现突出的优势，逻辑控制，智能方面，更换，扩大了测量，电路组成，控制电路数字逻辑电路，操作在很大程度上有了很多发展。但是，因为它具有系统停止，程序运行等关键缺陷，使之限制在一个很多重要环境中无法运用的情况。在很多抗干扰技术中，软件升级，设置添加看门狗电路等，可以解决这个问题，但仍然存在的问题还有很多，例如：看门狗的运行,意味着已经出现错误和运行一段时间,这是不可以在一些地方出现的,出现错误流通有时很多,但看门狗控制联系包括和进入,通过和程序的大门,这种错误看门狗无法看出；一个单片机等待外围硬件的运算需要大量的时间,将抗干扰程序进行运行,等待命令。对于这些情况，我们试图恢复单片机在外部运行的方式，采用或恢复单片机休眠状态下的方法。根据外部条件，一个单片机替代脉冲的方法。恢复后的程序，每次的单片机进行相应的程序，及时进入休眠完成后进行的任务，等待被恢复程序。解决了上述问题的这种方法，并得到更好的变压器综合保护结果。现在把51系列，作为一个例子，并把具体的方式和实施方法，作为程序的信号，来恢复单片机的正常运行。所列1.a原理和实现方法。

1.1恢复了成经常无条件运行的问题

使用定时器，专用时钟芯片或其它脉冲发生器，生产恢复程序的信号，定期根据间隔的设置。这种方法特别适用于测量仪器。实际上，在程序没有运行中，程序中的A/D转换器通常采用模拟量，然后将其存储显示。这当然是非常快，但稳定的阅读，每秒只能升级1-2倍，一对CPU的大量时间用于等待的数据。让CPU的开展和任务结束后直接进入休眠，恢复程序并唤醒外部运行，是要进行的下一个操作，这恢复了程经错误时进进入休眠状态的情况，这种方式可以使抗干扰能力大大增强，主要有2点:①。在休眠，程序停止运行，可以显示电脑的指标，导致无序程序运行和输出。工作时间的休眠比例1:9，即1秒时间有0.1秒测量使用，显示，有休眠时间0.9秒的概率该程序受到干扰的1/10，而运行全速，抗干扰能力提高10倍。②因为每1秒无条件恢复一次程序，一旦停止在目前的工作状态，等一定能够恢复时，就会恢复到下一次的程序。至于唯一的工具，显示，一些阅读错误，1秒出现意外，没有下一个测量记忆，是可以承受的，属于“合格”的错误。这种恢复了错误程序的把关，定期对看门狗电路有很大优势，首先，等待时间更改为休眠状态，时间缩短，并可能会受到干扰;第二，避免偶发的看门狗控制链接的错误循环的情况。1.2外部条件是恢复错误程序的关键有些地方，出口或措施是由外部控制。例如，热供暖方式，旋转的脉冲产生和计算出热水车热量，没有热水流动，没有出口的热量，CPU只需要保持数值，不需要计数。可以想像，热水水车转动温度停车时，CPU会处于一个等待的阶段，如果让其休眠，有水车轮脉搏不断，抗干扰能力也大大加强。因此，只要恢复了对水的车轮和CPU脉冲影响，水车轮旋转一圈，每次连接，CPU是恢复工作后，热表就可正常工作，这是恢复到程序能正常运行的方法。类似的应用，半电子电度表，在部分程序中断时，车轮和机械程度的循环转移，用户不需要电力，CPU已经知道所有的休眠时间。在恢复的时间间隔中经常不被复位，但据证实了该方法的外部条件。在某些情况下，在休眠的时间会很长，非常有效的提高抗干扰能力。2．硬件实现的主要问题

2.1定期恢复到可运行程序的状态

一般有2种方法。①使用theitimer或专用芯片时钟恢复程序。图1，为了使用的时间电路，555电路构成，可以使用X1126等，也唤醒了CPU的报警信号后成立的预警时间的时钟芯片。这种方法适用于长时间休眠，也可以按照这个操作的结果，确定唤醒时间，在下次警报时恢复，非常灵活方便。②在使用该系统固有的信号，是将减少经常脉搏。使用50赫兹的频率来减少脉冲频率，已经省略了计时器，聚集的地方测量阶段在同一时间的电流信号的图，相应的信号。2.2外部条件恢复到可运行程序的状态发送外部条件的脉搏，使恢复程序，重新直接的一个重要阶段。为此，上述水车轮或电表脉冲产生的花费，可以使用施密特触发器有一个新面貌，为写下最大或最小，可以使用窗口比较工具。为了实现电子化监管，可以使用电子电位器，建立中，随着单片机需求持续降低脉冲。2.3缩短周期，恢复了可运行程序高平时的电力在图3，恢复了程序信号在高级别输出时，一个芯片的电脑在恢复可运行程序的状态，程序不运行，抗干扰能力是最强的，在高层次，一个芯片计算机开始运行的行为过程。这就是说，是恢复程序和时间的程序进行期间信号运输，这个时候应大于该程序每次执行周期。这是恢复执行周期和恢复执行信号非常重要的地方，选择合理方法。至于简单的仪器显示，恢复程序的周期确定的数据打破循环，低电力是它的措施，对所有显示的时间要大于平时，
