It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to deviate from the gist of the present invention.

1 is a view showing the configuration of a remote control device having a bidirectional communication function according to the present invention.

The remote control apparatus according to the present invention is composed of a remote control 100 and the transmission and reception module 200 provided in the electronic device.

The transmission / reception module 200 includes a second receiver 110, a response signal generator 120, and a second transmitter 130.

The second receiver 110 is controlled by a control unit (not shown) or a separate control unit (not shown) of a conventional electronic device, and receives control data having its own custom code according to an infrared communication method, and receives the response. The signal generator 120 outputs the signal.

The response signal generator 120 receives the control data and buffers the buffer for a predetermined time (123) and the NOT operator 125 for NOT calculating and outputting the control data output to the buffer 123. It consists of. That is, in the present invention, the NOT operation of the control data is used as the response signal.

The second transmitter 130 transmits the NOT operation, that is, the inverted control data, as a response signal to the remote controller 100 according to the infrared communication method.

The remote controller 100 includes a control unit 10, a storage unit 20, a key input unit 30, a display unit 35, a first transmitter unit 40, a first receiver unit 50, and a timer 60. .

The key input unit 30 includes a plurality of function keys such as numeric keys for controlling a plurality of electronic devices and a plurality of macro setting keys, and generates key data for the keys and outputs the generated key data to the controller 10.

The storage unit 20 stores an area for storing a control program for controlling the operation of the remote controller 100 according to the present invention, an area for temporarily storing data generated during the execution of the control program, and a key code for each of the keys. And an electronic device name and custom codes for each of the plurality of electronic devices, and an area for mapping and storing the key code and at least one or more custom codes for the key in which the macro function is set.

The display unit 35 displays the operation state and the current mode information of the remote controller and displays the electronic device name which has not received the control data according to the present invention.

The first transmitter 40 receives the control data from the controller 10 and transmits the control data by an infrared communication method.

The first receiver 50 receives a response signal from the transmission / reception module 200 by an infrared communication method and outputs the response signal to the controller 10.

The controller 10 receives key data for an arbitrary key from the key input unit 30 and determines whether the key data is macro function key data, and if the key data is key data for which a macro function is set, the key data is input to the key data. It generates a control data including a key code for each and a custom code mapped to the key code. In other words, if a first custom code, a second custom code, and a third custom code are mapped to the key code, the controller 10 may include first control data, a key code, and a first code including the key code and the first custom code.

After the transmission of the control data, the controller 10 proceeds to step 215 to drive the timer 60 to count the time.

When the timer 60 is counted, the controller 10 initializes (N = 0) the count number of control data transmission for each electronic device in step 217.

After the control data transmission is initialized, the control unit 10 checks whether the response signal is input from the first receiving unit 50 within a predetermined time through steps 219 and 225, and proceeds to step 221 when the response signal is received within the predetermined time. .

The controller 10 proceeds to step 221 and inverts the response signal and detects a custom code from the inverted response signal.

When the custom code is detected, the controller 10 compares the custom code mapped to the custom code mapped to the key code for the macro key and transmits the control data within the predetermined time through steps 223 and 225. Check if a response signal is received from the electronics.

If it is determined in step 223 that the response signals are received for all the electronic devices, the controller 10 ends the process, and if there is an electronic device that does not receive the response signal until the predetermined time is exceeded, the control unit 10 proceeds to step 227. .

The control unit 10 proceeds to step 227 checks whether the number of times the control data transmission exceeds the reference number of times.

If the counted control data transmission number exceeds the reference number, the control unit 10 ends the process. If not, the control unit 10 proceeds to step 229 and regenerates the control data for the electronic device that has not received the response signal, and then transmits the first transmission unit. Retransmit through 40.

After retransmitting the control data, the controller 10 proceeds to step 231 to increase the control data transmission frequency for the electronic device that has not received the response signal by 1 and proceeds to step 219 to repeat the process after step 219. .
