Because the keeping function of electric capacity, can39。 For writing down the instrument of the biggest or minimum， can use the window parator. In order to realize the electronization that is regulated， can use the electronic electric potential device, establish upper and lower limits with the order of the onechip puter. Reduce cycle and restored to the throne the high electricity at ordinary times In Fig3, restored to the throne the signal during high level Tr, the onechip puter is in the state of restoring to the throne, the procedure does not run, antiinterference ability is the strongest。 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。s circuit for guarding the gate regularly, first, change waiting time into a dormancy state, time to shorten and may be interfered。 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。 Combine the instance, analyse the characteristic of the hardware and software design under these kind of operation way. Keyword: Onechip puter Restore to the throne /dormancy antiinterference Foreword Introduction: With the development at full speed of the microelectric technique, the performance of the onechip puter improves rapidly, demonstrate the outstanding advantage in the operation, logic control, intelligent respect, replaced and enlarged the measuring that the circuit made up, control circuit by digital logical circuit, operation originally to a great extent, use very extensivly. But because it have system halted, procedure run critical defect of flying etc, make it limit in a lot of important application of occasion. A lot of technology in antiinterference , for example set up the software trap, add thehardware to guard the gate in dog39。 海軍大連艦艇學(xué)院本科生外文翻譯 第 1 頁(yè) 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 improve the antiinterference ability method of the onechip puter。Analyse its scope of application, provide and use the circuit concretly。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。 ③ In measure and control cycle among the long system, onechip puter spend wait for the peripheral hardware a large amount of time, will be interfered too when carry out and wait for the order. To these situations, we have tried the method restored to the throne voluntarily in practice, alternate pulse of adopting etc or restore to the throne waking according to external terms to the onechip puter up. After being restored to the throne each time, the onechip puter carries out the c
