Digital Signal Reapply Device and Reapply Method

摘要

The present invention, in the signal processing or data processing unit performing a designated function according to the application of the digital signal, reads whether the operation of the device is completed after the digital signal is applied, if the operation is not completed within a certain time to re-receive the digital signal The present invention relates to a digital signal reapplying device and a reapplying method for inducing a reliable operation of a signal processing or data processing device by applying the same. In addition to the signal applying unit 10 and the function performing unit 20, which are conventional components, A signal reapplying unit 100 for transmitting a digital signal which is an output signal of the signal applying unit 10; A time-lapse notifying unit 120 for outputting a time-lapse signal when a predetermined time has elapsed since the digital signal output time point; And a re-approval determination unit 110 for causing the signal re-approving unit 100 to re-output the digital signal according to whether the time-lapse signal is input and the operation completion state of the function performing unit 20 is included. When installed on a signal line connected to an important data line or an application program, it can not only eliminate problems such as loss of important data or stop the application program, but also allow the signal to be reapproved only a certain number of times. In this case, it is a useful invention to secure the reliability of the device and to facilitate the maintenance of the device, which makes it possible to easily detect the failure of the important device by judging the failure of the operation performing device.
