Abstract

본 발명은 마이콤 제어회로에 있어서, 전원주파수를 외부 인터럽트 신호로 이용하는 마이콤에서 흔히 발생하던 외부 인터럽트 신호의 노이즈 현상으로 기인되는 마이콤 제어의 오동작을 배제할 수 있도록 한 마이콤의 인터럽트 신호 노이즈 제거방법에 관한 것으로, 전원을 공급하는 전원공급수단(17)과, 일정 인터럽트 신호를 발생하는 인터럽트 신호 발생수단(20)으로 부터 입력되는 인터럽트 신호의 한주기에 해당하는 시간동안 내부 타이머 장치(45)에서 발생되는 클럭펄스의 수를 근접 창출하고, 이 클럭펄스 수를 카운트하여 인터럽트 신호의 한 주기에 해당하는 시간후에 입력되는 인터럽트 신호만을 한 주기로 인식하는 마이콤(30)과, 상기 마이콤(30)의 제어로 구동되는 구동회로 수단(40)으로 구성된 것을 특징으로 한다.The present invention relates to a method for removing an interrupt signal noise of a microcomputer in which a malfunction of a microcomputer control caused by a noise phenomenon of an external interrupt signal commonly generated in a microcomputer using a power source frequency as an external interrupt signal is eliminated. The clock generated by the internal timer device 45 for a period corresponding to one cycle of the interrupt signal input from the power supply means 17 for supplying power and the interrupt signal generation means 20 for generating a predetermined interrupt signal. The microcomputer 30 generates the number of pulses in close proximity, counts the number of clock pulses, recognizes only the interrupt signal input after a time corresponding to one period of the interrupt signal, and the microcomputer 30 is driven by the control of the microcomputer 30. Characterized in that the drive circuit means 40.
