Next, operation of the apparatus according to the embodiment of the present invention having the above-described configuration will be described with reference to the accompanying flowchart.

First, the operation in the telephone will be described with reference to the flowchart shown in FIG.

When a ring signal is applied from the CO line for the user to make an external call or the like and is detected through the ring signal detecting unit 2 (step ST1), the microprocessor 19 counts the number of times the ring signal is input. It is determined whether the count value reaches a predetermined value or more (steps ST2 and ST3).

At this time, if the ring signal input is interrupted for a predetermined time due to the ring signal being input and the external user disconnects the phone, the count is reset and then terminated (steps ST4 and ST5).

On the other hand, if it is determined in step ST3 that the ring signal has been input a predetermined number or more times, the microprocessor 19 executes the call path connection by turning on the call path connection unit 6. In addition, the microprocessor 19 controls the DSP 13 along with the call connection to transmit the auto-response message stored in the voice data storage unit 12 to the trunk line through the codec 14.

Subsequently, after the automatic response message is sent, the microprocessor 19 executes a normal automatic response function (step ST6). In this case, if an external user operates a dial button, the microprocessor 19 If a DTMF signal corresponding to the corresponding dial button is detected through the DTMF detection unit 9 by inputting a password, the microprocessor 19 compares the input password with the password stored in the password storage unit 11 (ST7). step).

Subsequently, when it is determined that the input password and the password stored in the password storage unit 11 match, the microprocessor 19 controls the DSP 13 to store, for example, the information stored in the guide message storage unit 15. , The electric rice cooker is 1, the refrigerator is 2, the washing machine is 3, ... outputting a guide message via the codec 14 via the codec 14 to request the selection input of the desired home appliances for the external user (ST8 step).

On the other hand, if there is no input of data relating to the home appliance control function in step ST7, the microprocessor 19 executes the normal autoresponder function and ends (step ST9).

In step ST8, if a selection input of a desired home appliance is requested to an external user and no selection data is input through the DTMF detection unit 9 even after a predetermined time elapses (steps ST10 and ST11), a microprocessor ( 19 controls the DSP 13 to send out an error message and terminate (step ST12).

However, when the selection data is input through the DTMF detection unit 9, the microprocessor 19 stores the input data in the memory 10 (step ST13). Then, the data stored in the memory 10 is read out, modulated by the modulator 16, and transmitted as frequency data of the radio signal (step ST14).

Accordingly, the frequency signal transmitted from the telephone is received by the television receiver and controlled to supply power to the corresponding outlet.

Thereafter, when the call path is turned off due to an external user hanging up the phone (step ST15), the microprocessor 19 turns off the call path connector 6 and terminates the function.

On the other hand, the operation in the television receiver will be described with reference to the flowchart shown in FIG.

In the television receiver, power is supplied from a power supply unit (not shown) to be in an operation standby state (step ST1).

In the operation standby state, when the frequency signal transmitted from the above-described telephone is received by being demodulated through the amplifier 22 and the demodulator 23 (step ST2), the controller 26 opens the code data memory 27. It is determined whether the code data received through the code data for controlling the terminal port of the power control unit 25 (ST3 step).

Then, the control unit 26 applies a high level signal to the corresponding terminal port of the power control unit 25 (ST4 step).

Therefore, the relay driver S is driven on by the high level signal applied to the corresponding terminal port, and as the relay switch RY is turned on, the main power is supplied to the home appliance connected to the corresponding outlet P. do.

Then, as the main power is supplied to the outlet P, the corresponding LED light emitting device of the display unit 28 blinks to indicate the power-on state of the outlet P.

That is, according to the above embodiment, the user can control the home appliance in his / her home through the telephone from the outside, thereby greatly improving the user's convenience.

In addition, this invention is not limited to the said Example, It can variously deform and implement within the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, it is possible to realize a home appliance control system of a television receiver using a telephone that allows a user to control a home appliance using an external telephone.
