【正文】 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 Unconditional regular reset Use timer, special clock chip or other pulse generator in a certain part of the regular produce reset signal. This method is especially suited for measuring instrument。 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。給系統(tǒng)設置一個復位按鈕，那就是說一個共同的復位，此按鈕是不是加入復位，要看最后并聯(lián)在電容兩端的引腳接地情況。 2 硬件的具體主要點 定期無條件復位 一般有兩種方法：①使用定時器或特殊用途的時鐘芯片來復位或使用由 555 電路組成的時鐘電路可以使用時鐘 芯片的又 X1126等設立預警時間后通過報警信號喚醒 CPU。這種方法尤其適合于測量儀器。智能維護邏輯控制電路取代了以往的測量電路的數(shù)字邏輯控制電路，并將其發(fā)展。至于唯一的數(shù)據(jù)顯示，雖然有些讀入數(shù)據(jù)在 1秒內出現(xiàn)錯誤但對下次測量沒有影響或可以承受的都屬于可忽略的錯誤。 在日常生活中減少周期和復位的用電量 復位信號在高層次的 TR 和單片機是在程序不運行時抗干擾能力是最強的，之后高層次的單片機開始進行執(zhí)行程序。 Combine the instance, analyze the characteristic of the hardware and software design under these kind of operation way. Keyword: SingleChip Microputer Restore to the throne, dormancy, antiinterference Preface: With the development at full speed of the micro electric 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 extensively. 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 the hardware to guard the gate in dog39。t present forever the mistake of the intact executive program. Monolithic integrated circuit in Ts and Tr period all can effectiv
