Abstract

In the VTR system, when a power failure occurs, the memory immediately remembers the mode immediately before the power failure, and when the power failure is automatically restored to the mode before the power failure, it is a technology that continues the operation performed before the power failure.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a VTR system, and more particularly, to a traveling mode automatic traveling device and method for a VTR that automatically returns to a mode state before a power failure and continues operation before power failure when the power failure is restored.

In general, when the existing VTR is out of service during use and returns to power supply, the power supply is turned off after entering the stop mode. In this case, however, if the user wants to perform the previous state again, the user must repeat the operation operated before the power failure. This is a very uncomfortable factor for modern people who seek to be comfortable in recent years. This is especially true in the case of momentary power outages.

Accordingly, it is an object of the present invention to provide a system capable of automatically performing a mode by automatically returning to a mode state prior to a power failure when a power failure in the VTR system is restored.

In order to achieve the above object, in the present invention, if a power failure is detected, the mode data before the power failure is recorded in a predetermined data means, and the power is retained using the power backup means. The power failure mode data retained is used to restore the previous power failure mode.

1 is a system block diagram of the present invention configured to perform as described above, the keypad 10 having keys corresponding to predetermined functions and modes, and when these keys are pressed to generate and output data to a machine corresponding thereto, By scanning the data of the keypad 10 at all times to receive the output data of the keypad 10 and the control unit to control each part to perform the corresponding operation, under the control of the ciscon 30 to control the VTR mechanism When the driving unit 40, the power supply unit 20 to receive the commercial exchange and smooth the partial pressure rectification and supply to each part, and receives the output voltage of the power supply unit 20, and detects whether there is a power failure therefrom and the backup battery using the backup battery The power supply sensing and backup unit 50 outputs the backup power and simultaneously outputs a power failure sensing signal, and receives the state data from the scissor 30 and the keypad 10 to detect the power supply and back. Unit time to be supplied from 50 to the electrostatic sensing signal activated state constitute the mode data to the mode recovery section 60 for supplying to the sheath cone 30.

Hereinafter, an embodiment of the present invention will be described based on the above configuration.

First, when the sheath cone 30 receives key data corresponding to a predetermined function from the keypad 10, the system controller 30 sets the mode to the corresponding mode, and then controls the driving unit 40 to operate the system in a form corresponding to the input function. Let's do it. The power detection and backup unit 50 includes a backup battery and normally receives rectified smooth power from the power supply unit 20 to charge the backup battery. The mode recovery unit 60 receives data about the mode from the keypad 10 or the scissor 30 and stores the data whenever the mode is changed. In this state, if there is a power failure, the power detection and backup unit 50 detects that the power failure has occurred and at the same time the power failure sensing signal along with the backup power is transmitted to the mode recovery unit 60. The backup power supply is maintained while the data on the mode that the sheath 30 is being stored is kept. When the power is restored again after a predetermined time, the sheath cone 30 accesses the mode data of the mode conversion unit 60 to continue in the mode before the power failure. Thus, when the power failure is restored, the user does not have to perform the key operation operated before the power failure.

Therefore, the present invention has an advantage that the user is considerably convenient because the power failure automatically occurs when the power failure is released again.
