【正文】 e procedure each time. It is restore to the throne cycle and restore to the throne high level of signal take empty than very much important to choose rationally. As to simple to show instrument, restore to the throne cycle determine data break cycle, low electricity is it measure, hancl over all time shown to greater than to want at ordinary times。 Second, avoided happenning that the dog controls the death circulation of the link to include guarding the gate. The external condition is restored to the throne the law Some arrival that export or measure is controlled by the outside. For instance, the hot form of heating, rotate the pulse produced and calculate heat by hot water water wheels, there is no hot water to flow, there is no heat to export, CPU only need in fact keep number value, do not need to count. Can imagine hot water water wheels rotate when parking warm , CPU idle in will it be will it be one season autumn spring and summer, If let dormancy its , measure have water wheels pulse constantly, antiinterference ability can strengthen greatly. So, so long as link up the restoring to the throne of the pulse of the water wheels and CPU, the water wheels rotate a circle each time, CPU is restored to the throne once, hot form can work normally , this is restored to the throne the law by the external condition . Similar application have half electron kilowatthour meter , go on one count just when the machinery degree wheels and transfers to a circle, users do not need the electricity, CPU has been knowing the dormancy all the time . The restoring to the throne in the interval not to be regular, but confirmed according to the external condition of this method. In some occasions, the time of the dormancy will be very long, very effective to improving antiinterference ability. 2 . The hardware realizes the main point Restored to the throne regularly unconditionally Generally have 2 kinds of methods. ① Use theitimer or the specialpurpose clock chip to be restored to the throne. Fig1, in order to use the timing circuit that 555 circuit makes up。s circuit etc, can make this problem havebetter settlement, but still the existing problem: ① Guard the gate dog at the movement, mean and appear mistake already and run some time, this is not allowed in some occasions。這文章只是充當一些探索，從這兩個方面努力，希望這些小小的建議，可以發(fā)揮一些效果，鑄造拋磚引玉，幫助大家，也希望每為同時共同探討，提高我們設(shè)計水平。 結(jié)果 ： 反干擾是電子設(shè)計中的重要問題，尤其是在單片機中。 具有電力測量，手動復(fù)位 有些系統(tǒng)在它初始化和運行時還是需要第一次電脈沖。這是復(fù)位周期的復(fù)位高電平采取占空比的非常重要的選擇理由?？梢岳么翱诒容^器得到儀器的最大最小值。這種方法適用于間隔時間比較長的情況下，還可以按照對這次行動結(jié)果，快速確定下次喚醒的時間，非常靈活方便② 信號的固定使用制度是為降低脈沖
