Keyword: One-chip computer Restore to the throne /dormancy anti-interference Foreword Introduction: With the development at full speed of the micro electric technique, the performance of the one-chip computer 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 anti-interference , for example set up the software trap, add the hardware to guard the gate in dogs circuit etc, can make this problem have better 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; ②Procedure appear circul
