Description

Lock device of remocon for TV control

The present invention relates to a remote control, and in particular, when receiving a specific broadcast and watching through a CRT, the occurrence of a case where the reception channel is switched to another channel or the power is cut off due to misuse of the remote control due to children's misuse. The present invention relates to a lock device for controlling a remote control, which is provided with a lock function in the remote control to prevent remote operation of the television using the remote control when selecting the lock function.

In general, it is difficult to provide all these keys on the front of the main body of the home appliance because of the increasing number of keys for using the functions due to the variety of home appliance functions. In order to eliminate the inconvenience of having to operate in close proximity to the remote control, a remote controller (Remote Controller: commonly referred to as a Remocon) that allows wireless key input from a remote location is widely used.

The operation of the remote controller will be described in detail. As shown in a block diagram of a conventional remote controller and a home appliance of FIG. 1, the remote controller 100 includes a key input unit 110, a control unit 120, and a remote signal output unit. 130 and an operation display unit 140, the home appliance 200 (in a preferred embodiment of the present invention, a television) includes a receiver 210, a signal processor 220, a controller 230 and a driver 240 It includes.

In the drawing, when the remote controller 100 receives a predetermined key signal corresponding to a user's key operation from the key input unit 110 having a plurality of keys for performing a plurality of functions, the control unit 120. ) Applies key data corresponding to the applied key signal to the remote signal output unit 130.

At this time, the remote signal output unit 130, the predetermined infrared carrier wave is amplitude-modulated based on the transistor TR1 based on the key data from the control unit 120 is transmitted through the infrared light emitting diode D1, the home appliance 200 ), The receiving unit 210 receives an infrared carrier from the remote signal output unit 130 of the remote controller 100 through a photodiode, and the received electrical signal is applied to the signal processing unit 220, and the signal processing unit 220 Amplification, detection, and waveform shaping of the applied electrical signal are performed to apply the key data to the controller 230.

Then, the controller 230 controls the driver 240 based on the key data applied from the signal processor 220 to drive the corresponding operation, thereby controlling the operation of the home appliance remotely.

Meanwhile, the controller 120 of the remote controller 100 includes a separate control port for displaying the operation state of the remote controller, and when a predetermined key signal is applied from the key input unit 110, the predetermined key is input to the remote signal output unit 130. The key data corresponding to the signal is output, and the key data is loaded on the infrared carrier to be transmitted.

Accordingly, the television receives the remote control signal transmitted from the remote control to control the overall operation of the television. That is, the control unit 120 for controlling the overall operation of the television is to remotely control the operation of the television by decoding the received remote control signal.

By using the remote control, the user can operate remotely without using the front button of the television when watching TV, and the ordinary user performs functions such as changing the channel or turning on / off the power and adjusting the volume of the remote control. I use it a lot.

However, in contrast to the above-described convenience, the channel is frequently changed due to an operation error of the remote controller while watching a specific broadcast channel through a television. In particular, when there are children in the home, children often use the remote control as a toy, and thus, often, the user cannot watch important scenes due to the channel change and power on / off.

An object of the present invention for solving the problems of the prior art as described above is to receive a specific broadcast and watch through the CRT, while the reception channel is switched to another channel due to mischief of the children due to the operation error of the remote control or In order to prevent the occurrence of the power off, there is provided a lock device for controlling the remote control to prevent the remote operation of the television using the remote control by providing a lock function in the remote control operation.

A feature of the present invention for achieving the above object is to receive a key button signal according to the key matrix provided in the key input unit, and converts the corresponding remote control signal into a data code subsequent to the header code and the custom code and outputs the same. A remote control comprising a control unit and a remote control signal output unit for converting and outputting a signal generated by the control unit into a wireless signal such as infrared rays for outputting; A key button unit for requesting a lock function of a remote control provided with a specific lock button for requesting the lock of key button signals generated on the key matrix, and on the key input unit for selecting the lock function of the remote control When the lock button is selected, if there is no specific password input, the control unit ignores the user's request according to the selection of all the key buttons on the key input unit and stops the operation of the remote signal output unit.

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

2 is an exemplary configuration diagram of a remote control device according to the present invention, in which a lock button 1 on a key input unit 110A for selecting a lock function of a remote control and a specific password input when the lock button 1 is selected If not present, the controller 120A disregards the user's request according to the selection of all the key buttons on the key input unit 110A and stops the operation of the remote signal output unit 130, and outputs the remote control signal generated by the controller 120A. It is composed of a remote control signal output unit 130.

Looking at the operation of the lock device of the remote control adjustment according to the present invention configured as described above, the user selects the lock button (1) on the key input section (110A) when the child uses the remote control as a toy while watching television.

Accordingly, the controller 120A determines whether the lock button 1 is selected at all times and then determines whether the user inputs a specific password preset when the lock button is selected. In addition, the remote control request according to the selection of all key buttons on the key input unit 110A is ignored.

Accordingly, if there is no specific password input, even if any key input occurs, the request is ignored and the operation of the remote signal output unit 130 is turned off.

Then, when the user wants to reactivate the remote control function of the remote controller again, the key buttons corresponding to the set password are sequentially pressed among the key buttons representing the Arabian number on the key input unit 110A. The control unit 120A releases the lock function and performs the normal remote control function.

By providing a lock device for controlling the remote control according to the present invention that operates as described above, children can watch the important scene of the channel broadcasting that is currently being watched when the remote control is used as a toy according to the change of the channel currently being watched or the power off operation. The conventional problem that could not be solved can be solved.
