Detecting and repairing malfunction of microcomputer controlling oil burner

摘要

The present invention relates to a malfunction detecting and restoring method of a micom for controlling an oil burner. More particularly, the present invention relates to a malfunction detecting and restoring method for a micom in which an output of a microcomputer (40) A first step (108-110) of judging whether the control pulse signal is feedback-fed back to the control pulse signal which is fed back in the first step; and a control step of controlling the microcomputer A second step (111 to 115) for resetting the state flag of the register unit (30) indicating the operation state of the blowing motor, the electromagnetic pump and the solenoid valve to the operation flag to output a signal, If the microcomputer 40 fails to output the normal control pulse signal despite resetting the state flag of the oil burner 30 to the operation flag, the microcomputer 40 is reset, It includes a third step (116 107) to suspend the copper, the microcomputer can prevent a fire due to overheating through the combustion of the oil burner, which may occur if the do not normally outputs a control pulse signal due to noise or the like.
