外文資料翻譯--單片機(jī)的休眠運(yùn)算復(fù)位和抗干擾能力完善-單片機(jī)(存儲(chǔ)版)
【正文】 gether． 。s circuit for guarding the gate regularly, first, change waiting time into a dormancy state, time to shorten and may be interfered。就這么一說(shuō)對(duì)單片機(jī)整個(gè)發(fā)展來(lái)說(shuō)是不夠的，我們要研究如何降低干擾風(fēng)險(xiǎn)，使它完善以減少不必要的錯(cuò)誤。當(dāng)程序的時(shí)間很長(zhǎng)，盡量要求降低TR，可以加入電路鑒別。在這上面提到的水車(chē)輪或電流表產(chǎn)生脈沖也可以使用施密特的觸發(fā)代替會(huì)有個(gè)新的效果。所以，只要把復(fù)位的脈沖水車(chē)輪和 CPU 連接其來(lái)，水車(chē)輪每轉(zhuǎn)一圈 CPU 復(fù)位一次，供暖才能正常進(jìn)行，這就是復(fù)位法的外部條件。工作時(shí)間與休眠時(shí)間比例為 1： 9，那就是說(shuō) 1 秒內(nèi)有 秒時(shí)間是用于測(cè)量，傳送，顯示，有 秒時(shí)間是休眠。③在測(cè)量和控制周期之間的時(shí)間長(zhǎng)時(shí)，單片機(jī)要花費(fèi)大量時(shí)間等待周邊其他硬件，在運(yùn)算處理等待命令時(shí)它將會(huì)受到太多的干擾，對(duì)于這些情況，在實(shí)踐中我們己經(jīng)嘗試過(guò)主動(dòng)復(fù)位的方法，釆用后續(xù)脈沖外界條件觸發(fā)單片機(jī)工作。 淮 陰 工 學(xué) 院 畢業(yè)設(shè)計(jì) (論文 )外文資料翻譯 學(xué) 院 ： 電子與電氣工程學(xué)院 專(zhuān) 業(yè)： 電氣工程及其自動(dòng)化 姓 名： 周晶 學(xué) 號(hào)： 1081205737 外文出處： Microcontroller and embedded systems ( 用外文寫(xiě) ) applications 02 of 2020 附 件： ； 。②程序時(shí)常出現(xiàn)很多電路錯(cuò)誤，僅僅是狗的連接環(huán)節(jié)也會(huì)時(shí)常出現(xiàn)無(wú)法識(shí)別的錯(cuò)誤。其有兩個(gè)主要內(nèi)容：①在休眠（程序停止運(yùn)行）時(shí)可以出現(xiàn) CPU 機(jī)指示無(wú)序的程序?？梢韵胂鬅崴?chē)輪轉(zhuǎn)動(dòng)時(shí)保持溫度， CPU 空閑，它可能會(huì)有高溫情況，如果讓其有休眠情況，并衡量水車(chē)脈沖不間斷，其反干擾能力可以得 到大大的加強(qiáng)。 外部條件復(fù)位 發(fā)送外部條件脈沖復(fù)位后立刻有了新的進(jìn)展。單片集成電路在 TS 和 TR 時(shí)期里 都可以有效的抗干擾，但最好是不必要的時(shí)間安排 TR。干涉可能導(dǎo)致該系統(tǒng)停止運(yùn)行，也可能引發(fā)個(gè)種錯(cuò)誤或非法轉(zhuǎn)移，使整個(gè)系統(tǒng)產(chǎn)生死機(jī)的錯(cuò)誤。 this kind of method is especially suitable for the measuring instrument. In not running actually, sample the analog quantity of introduction with A/D converter often, then store showing. This course is very fast, but steady for reading, the data per second are only upgraded 1 2 times, a large amount of time of CPU is used for waiting. Let CPU carry out and enter dormancy directly after the task , restore to the throne and wake by external world up It carry out the next operation, this is to restore to the throne the law regularly In this way can make antiinterference ability strengthen greatly , have 2 points mainly: (1)At the dormancy, procedure stop run can appear PC indicator disorderly procedure that causes run and fly. Work time in dormancy proportion 1:9, that is to say 1 s have time of s used for measuring, sending off showing, there is time dormancy of , the probability that the procedure is interfered is 1/10 while running at full speed, whole antiinterference ability raise by 10 times. (2)Because every 1s is restored to the throne once unconditionally, once present the system halted during a job, can certainly resume when restored to the throne next time. As to only instrument that show, some reading mistake that is appear accidentally there is no memory to the next measurement, be could bear, belong to pass mistake. This kind is restored to the throne the advantage of dog39。t present forever the mistake of the intact executive program. Monolithic integrated circuit in Ts and Tr period all can effectively the antigambling, but is best the unnecessary time arrangement in Tr. When the program time is long, as
