【導讀】和分析其所使用的電路，結(jié)合實例分析在某些運行方式下的軟硬件設(shè)計。隨著微電子技術(shù)迅速發(fā)展，單片機性能也得到迅速提高。智能維護邏輯控制電路取代了以。這操作被擴展到更大的范圍，并得到廣泛使用。因為它有系統(tǒng)的停頓，所以運行程序有致命缺陷在許多重要場合受到限制。很多反干擾技術(shù)（例。電路錯誤，僅僅是狗的連接環(huán)節(jié)也會時常出現(xiàn)無法識別的錯誤。③在測量和控制周期之間的時。在每次復位后單片機將進行相應的程序，執(zhí)行命令后立即進入休眠，為下次復位做好準。使用定時器，專用時鐘芯片或其它脈沖發(fā)生器在某一部分定期產(chǎn)生復位信號。其適合于測量儀器。在這種運行中，模擬量通過A/D轉(zhuǎn)換器后并將其存入顯示。干擾能力大大加強。CPU連接其來，水車輪每轉(zhuǎn)一圈CPU復位一次，供暖才能正常進行，這就是復位法的外部條件。該復位無規(guī)律間隔出現(xiàn)，但它被證實了是有根據(jù)的外。鐘電路可以使用時鐘芯片的X1126等設(shè)立預警時間后通過報警信號喚醒CPU。
【正文】 y, are restored to the throne and suitable for the time that the procedure carries out during the low level Td of the signal, this time should be greater than the execution cycle of the 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。 Otherwise, cant present forever the mistake of the intact executive integrated circuit in Ts and Tr period all can effectively the antijamming, but is best the unnecessary time arrangement in Tr. When the program time is long, when as far as possible the request reduces Tr, may join the differentiating circuit, like chart 1 center C30, R26, D9. Has the electricity to measure and restore to the throne manually Some system is it make some initialize and operate to want at electricity for the first time. Restored to the throne and already bee the beginning condition of normal running each time while adopting the way of restoring to the throne to run , it is unable to distinguish and have the electricity for the first time. In some pin connects the electric capacity of one ljIF to the ground, measure this pin after being restored to the throne, if low level to have electricity for the first time. Give system set up one restore to the throne button, that is to say a mon one manual to restore to the throne, this button is not joined and being restored to the throne in the end, is connected in parallel in the electric capacity both ends to the ground of abovementioned pins. Result: Conclusion Antiinterference is an important problem in an electronic design, especially Important in the onechip puter. This is because the onechip puter has procedures to run particularity that flies, the consequence that it is interfered may be the system halted, may send out various kinds of mistakes or illegal movements before the system halted too, make the whole system produce the mortality mistake. So, only guarantee it is not enough yet for onechip puter not to crash, study how to reduce the risk interfered, it can befaulttoierant how is it after and make mistakes. This text is it act as some exploration from two these to try hard, hope these elementary opinions can play some function of casting a brick to attract jade, helpful to everybody。 Hope too every colleague explore together, improve our design level together. 來源與中國知網(wǎng) ：
