【正文】 Hope to every colleague explore together, improve our design level together． 。 otherwise, it can39。 For writing down the instrument of the biggest or minimum, can use the window parator. In order to realize the electrification 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, 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。 (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 corresponding procedure, enters dormancy in time after finishing carrying out the task, wait to be restored to the throne neatly. Have solved abovementioned problems well with this method, and has got better result in the agricultural voltage transformer prehensive protector experiment. Now take 51 serial onechip puters as an example and probe into the concrete principle and implementation method, restored to the throne the signal as the high level. 1 A principle and implementation method
