Abstract
The present invention relates to a method for preventing system invalidation including the microcontroller transferring the specific packet to the primary electronic device which operates according to the operation commands sent from the upstream device to provide the specific service, the primary electronic device returning the return packet, the microcontroller receiving the return packet, the microcontroller determining if the return packet is returned within a preset rang, if yes, repeating the above steps, if not, activating the spare electronic device to take over the primary electronic device to provide the specific service, and shutting down power supply of the primary electronic device. Therefore, the present invention ensures the spare electronic device smoothly takes over the task of the primary electronic device which accidentally fails, thereby preventing the whole system from being invalidated and improving the stability and reliability of the system operation.
