【正文】 one beginning again, measure to Ts =0 but Td * 0, is it is it is it transmit power to try to cross already to indicate, at is it wait for the course of 30s to lose electrical power now. In this way, the whole process is transmitted each other by such these parameters as Tr, Td , Ts etc, go on step by step. 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。 But electricity or manual to rstore to the throne when pushing in conformity with zero clearing, is it embody to want when the software is worked outing at the beginning. If calculate time allows, try one39。 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. Treatment of output end sons (1) Restore to the throne straight pulse During all I/O mouth of onechip puter turn into the high level when restoring to the throne. That is to say output for low pin normally, will according to restore to the throne cycle appear the width for the straight pulse of Tr. This straight pulse will influence the normal output, 2 methods are dealt with: ① Connect in parallel electric capacity suppress , capacity confirm according to Tr time that restore to the throne on the son in end. Reducing Tr can be reduced and connected the electric capacity in parallel. ② It is invalid to design the peripheral circuit into the high level. (2) Faulttolerant Choose the capacity that the output end connects the electric capacity in parallel faulttolerantly and properly, can realize faulttolerant control. Reduced cycle in a certain, because interfered exporting the wrong level. Because the keeping function of electric capacity, can39。 Can use the clock chips of X1126 ,etc too , wake CPU up with the alarm signal after setting up warning time. This kind of method is suitable when the long interval is made, can also follow the result of this operation ， determine to wake time up in alarm next time temporarily, very flexible and convenient. ② The signal of using the system to be inherent is as reducing the pulse regularly. Use 50Hz worker power make reducing after having a facelift frequently, already omit the timer, gathered the corresponding signal for the phase place which measured the electric current signal at the same time, as Fig. 2 shows. External conditions are restored to the throne Send external condition pulse to and is restored to the throne the end son after having a facelift. To that abovementioned water wheels or the ammeter spend a pulse produced, can use Schmitt39。 ② Procedure appear circulation mistake very much sometimes, but just guard the gate dog control link include and enter, adopt and guard the gate as to such a mistake dog unable to discern。 海軍大連艦艇學(xué)院本科生外文翻譯 第 1 頁 Dormancy of the onechip puterrestore to the throne in the operation way and improve anti interference ability Abstract: Introduce a kind of dormancy of using restore to the throne in theoperation way and impr
