The present invention is applicable to all electronic devices equipped with a remote control, and in particular, when the power input to the electronic device is cut off or a power failure occurs, the data backup device using the remote control to transmit the current operating state to the remote control to back up the data And to a method thereof.

In general, in a conventional electronic device, a voltage applied to the electronic device is sensed to protect the data in operation at the time of sudden power-off or power failure, and the sudden input voltage is preset in the microcomputer. When the reference voltage falls below a certain voltage, the data is stored in the memory area backed up by the backup battery.

However, in this method, since the capacity of the backup battery and the storage time of the data backed up by the backup battery are proportional to each other, the capacity of the backup battery required to back up the data for a predetermined time must be large. Not only does the cost increase as the size increases, but there is a problem that the backup battery is completely discharged and cannot be used when the backup battery is not used for a long time.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to present the current operating data when the input voltage sensed by the voltage sensing means falls below the reference voltage preset in the control means. The present invention provides a data backup apparatus and method using a remote controller that can not only permanently protect the stored data by transmitting the data back to the remote controller, but also reduce the cost and reduce the size of the product.

In order to achieve the above object, a data backup apparatus using a remote controller according to the present invention includes a control means, voltage conversion means for converting a commercial AC power supply of an AC power input terminal into a DC power supply, and a voltage conversion means converted into DC power by the voltage conversion means. Voltage sensing means for sensing an input voltage, and a data transmission and reception means for receiving a control signal from the control means according to the input voltage sensed by the voltage sensing means and transmitting and receiving backup data to the remote controller and the control means. .

In addition, the data backup method using the remote control according to the present invention is a voltage sensing depth for detecting a change in the input voltage of the AC power input terminal, and the input voltage detected by the voltage sensing step and the reference voltage data set in the control means; The voltage comparison step for judging the cross-link, the backup backup step for transmitting backup data to the remote controller while generating a power failure signal, a return signal, and an initial signal according to the comparison result in the voltage comparison step, and the signal issued in the data backup step. Accordingly, it characterized in that it comprises a data return step for transmitting the back-up data to the control means.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the voltage converting means 20 is a transformer which receives a commercial AC power supplied from the AC power input terminal 10 and converts it into a predetermined DC power required for an electronic device and outputs the voltage. 30 detects the voltage of the AC power input terminal 10 converted to DC power by the voltage converting means 20, and the waveform shown in FIG. 3 at the input terminal of the control means which describes the detected voltage data. Output

In addition, the control means 40 receives the DC power output from the voltage conversion means 20 and at the same time receives the voltage detection signal output from the voltage sensing means 30 to initialize the electronic device as well as the overall operation. It is a microcomputer to control the, the key input means 50 is provided with a plurality of function keys to input the operation command desired by the user to the control means (40).

In addition, the data transmitting and receiving means 60 is the control means when the voltage sensing signal sensed by the voltage sensing means 30 is smaller than the reference voltage signal preset in the control means 40 (Yes). According to the control of 40, the current data in operation is transmitted to the remote controller 70, and the voltage sensing signal sensed by the voltage sensing means 30 is preset in the control means 40, which is a reference voltage signal. If larger (Yes), the data transmitted to the remote controller 70 under the control of the control means 40 is received.

Hereinafter, operation effects of the data backup apparatus and the method using the remote controller configured as described above will be described.

2A and 2B are flowcharts showing a data backup operation procedure using a remote controller according to the present invention. In FIGS. 2A and 2B, S denotes a step.

First, when power is supplied to the electronics, the voltage converting means 20 receives commercial AC power from the AC power input terminal 10 and converts it into a predetermined DC power required for the operation of the electronic device. Output to

Accordingly, in step S1, the DC power output from the voltage converting means 20 is applied by the control means 40 to initialize the electronic device.

Subsequently, in step S2, the voltage sensing means 30 detects the input voltage Vin of the AC power input terminal 10 converted by the voltage converting means 20 into DC power, and detects the detected voltage data Vin. Output to the control means 40.

Therefore, in step S3, the control means 40 determines whether the voltage data Vin sensed by the voltage sensing means 30 is in an initial operating state, and the voltage data Vin determined by the control means 40 is determined. Is in the initial operation state (Yes), the process proceeds to step S7 and the control means 40 returns to the step S2 while generating an initial signal (the 'S' point in FIG. 3), and the voltage converting means 20 The input voltage Vin supplied from the voltage is sensed by the voltage sensing means 30.

On the other hand, when the voltage data Vin determined by the control means 40 is not the initial operation state (No), the initial state signal does not need to be generated. It is determined whether the voltage data Vin sensed by the sensing means 30 is smaller than the reference voltage data Vref set in the control means 40 in advance.

As a result of the discrimination in step S4, when the voltage data Vin determined by the control means 40 is not smaller than the reference voltage data Vref (No), the process proceeds to step S5 where the power failure signal is transmitted to the electronic device. The control means 40 determines whether or not an occurrence has occurred, and when the power failure signal is not generated (No), the input voltage Vin supplied from the voltage converting means 20 is in a normal state. In response to an operation command input by the user to the control means 40 by the input means 50, the control means 40 returns to the step S2 while operating the electronic device normally, and repeats the operation of step S2 or less.

On the other hand, if the voltage data Vin determined by the control means 40 is smaller than the reference voltage data Vref (Yes) as a result of the discrimination in step S4, the electronic device has a power failure. In step S8 while generating a power failure signal (the 'P' point in Fig. 3) while transmitting the current data in operation under the control of the control means 40 to the remote controller 70 through the data transmission and reception means 60, the step S2 Returning to, the voltage sensing means 20 continuously detects the input voltage Vin supplied from the voltage converting means 20.

If the result of the discrimination in step S5 is that a power failure signal has occurred (Yes), the process proceeds to step S9 and the control means 40 generates a return signal (the 'Q' point in FIG. 3) while generating the return signal (step Q2). After returning, the input voltage Vin supplied from the voltage converting means 20 is continuously sensed by the voltage detecting means 30.

When the power failure signal, the return signal and the initial signal is generated in the main body of the electronic device as described above, the generated signal is received by the remote controller 70 through the data transmission and reception means 60 to perform a data backup operation. It demonstrates in detail with reference to FIG.

First, in step S10, it is determined whether the blackout signal (the 'P' point in FIG. 3) has been input to the remote controller 70 from the control means 40 through the data transmission and reception means 30, and the blackout of the remote controller 70 is determined. If a signal is input (Yes), the flow advances to step S11 to determine whether the return signal (the 'Q' point in FIG. 3) has been input from the control means 40 to the remote controller 70.

As a result of the discrimination in step S11, when a return signal is not input to the remote controller 70 (No), the flow advances to step S12, and the initial signal ('in FIG. S'point) is input.

As a result of the determination in step S12, when the initial signal is input to the remote controller 70 (Yes), the control means 40 is reset in the main body of the electronic device, that is, as shown in FIG. Since it is the case of the section ⓑ including the 'R' point (Reset voltage), in step S13, the backup data received from the control means 40 through the data transmission / reception means 60 is returned to the control means 40 again. While transmitting the backup data through the data transmission / reception means 60, the power failure signal (point 'P' of FIG. 3) input to the remote controller 70 is removed, and then the process returns to the step S10, where the power failure signal ('P of FIG. 3) is removed. Continue to determine if a 'point' has been entered.

At this time, when the electronic device is reset in step S13, the minimum time for transmitting the backup data from the control means 40 to the remote controller 70 through the data transmission and reception means 60 (reached in FIG. 3). Δt) is required.

On the other hand, when the return signal (the 'Q' point in FIG. 3) is input to the remote controller 70 (Yes) as a result of the determination in step S11, the control means 40 is not reset and the electronic device is not reset. In the case where a momentary power failure occurs, that is, the section ⓐ shown in FIG. 3, the remote controller 70 returns to the step S10 while removing the power failure signal and the return signal input to the remote controller 70 in step S14. It is continuously determined whether a signal (the 'P' point in Fig. 3) is input.

According to the data backup apparatus and method using the remote control according to the present invention as described above, the input voltage sensed by the voltage sensing means is set in advance in the control means so that the current operating data is dropped when the reference voltage falls below the reference voltage. Not only can the data stored on the remote control be backed up permanently, but the cost can be reduced and the size of the product can be reduced.
