In general, when you go out from an arbitrary place (home or office) and cannot be controlled remotely or at a short distance, you have to go back to the place and start the device you want.

Therefore, the housewife had a lot of personal work on the way out, and when it was later than the scheduled return time, there was a flaw that the cooking time was late.

SUMMARY OF THE INVENTION An object of the present invention is to provide a remote control device for driving a device installed at a long distance using an MFC telephone at a time desired by a user.

It is composed of supplying AND gate (AN ₂ ), and output control part is OA gate (OR ₃ -OR ₄ ), AND gate (AN ₂ -AN ₅ ), FF (F ₃ , F ₄ ), (F _{n -1} , F _n ), the light emitting device (LED ₂ ) (LED ₃ ), the light receiving sensor (CDS ₃ ) (CCS ₄ ).

5 shows the frequency relationship output from the numeric array of MFC telephones, and different low and low frequencies (F ₁ -F ₄ ) and high frequencies (F ₅ -F ₇ ) are assigned to each row and column of the number plate. If the number 5 is selected, low frequency f ₂ and high frequency f ₆ are generated by the matrix and transmitted to the telephone line.

Here is an example of the assignment of low frequencies (f _1- f ₄ ) and high frequencies (f ₅ -f ₇ ).

f ₁ = 697HZ f ₂ = 770HZ f ₃ = 852HZ f ₄ = 941HZ f ₅ = 1029HZ f ₆ = 1336HZ f ₇ = 1477HX

The remote control apparatus of the present invention having the configuration as described above will be described in detail.

First, before looking at the operating relationship of the present invention, the user selects an arbitrary digit from among the ten tones aj output from the tone decoder unit and inputs each to the oragate OR ₁ -OR ₄ . The operating relationship of the present invention will be described by taking an example of applying the output of the NAND gate N ₁ of the concoder unit, that is, the digit (a) signal, to the input terminal of the OR gate OR ₁ OR ₂ .

When the user first calls the subscriber line L ₁ (L ₂ ) using the MFC telephone line, the call current corresponding to the ring tone output from the telephone station is transferred to the input control unit through the subscriber line L ₁ (L ₂ ). Is approved.

When a call current corresponding to a ringing tone is applied to the input control unit, a counter (not shown) in the automatic answering circuit receives the rectified frequency and counts the frequency corresponding to the subscriber's telephone number (XXX- △△△△). The instantaneous light emitting device LED ₁ emits light and is applied to the light receiving sensor CDS ₁ (CDS ₂ ). The subscriber lines L ₁ and L ₂ are connected to each other to form a loop, and the subscriber telephone number ( The frequency after XXX-Δ △△△ is applied to the input terminal of the filter described later through the light receiving sensor CDS ₂ and the capacitor C ₁ , and is input to the tone decoder unit through the capacitor C ₂ . .

Here, the operation of the filter used in the tone decoder unit and the input control unit is briefly described. When the corresponding frequency is input to the input terminal according to the characteristics of each filter, the output terminal S ₁ is "high" and the state S ₂ is "low". In contrast, when a frequency other than a specific frequency is input, the output terminal S ₁ is in the "low" state, and S ₂ is in the "high" state.

When the frequency corresponding to the intermittent sound (call completion signal) is input to the filter in the input control part, the output terminal S ₂ is turned into a low state as described above. Thus, the reset signal is reset to the counter of the automatic response circuit. ) Is applied to the initial state.

MFC Telephone Selecting Subscriber Line The frequency selected by the user after the subscriber's telephone number (XXX- △△△△) is input through the filter (FT ₁ -FT ₇ ) through the light receiving sensor (CDS ₂ ) and the capacitor (C ₂ ). Applied to each terminal.

Here, when the user selects No. 1 in the numeric array of the telephone as shown in Fig. 5, the corresponding frequencies f ₁ = 697HZ and f ₅ = 1029HZ are applied to each filter FT ₁ -FT ₇ . .

Therefore, the output terminal S ₂ of the filter FT ₁ (FT ₅ ) becomes "low" and conversely, the output terminal S ₁ becomes "high", so the power supply voltage Vcc is bypassed through the output terminal S ₂ . is therefore applied to the end, "low" signal on both sides of the input terminals of the NOR gate (N ₁₎ the output of the NOR gate (N ₁₎ becomes a "high" state.

Therefore, the user selects the numeric array of the MFC phone so that the "high" signal is outputted to the output of the no-gate connected to the input terminal of the OR-OR (OR ₁ OR ₂ ) of the password decryption unit. If is selected, the output of the OR gate (OR ₁ ) goes from the high "high" to the "low" state, and the pulse down edge signal is applied to the clock terminal (CK) of the FF (F ₁ ). ) output is "high" the signal is applied to one side input terminal of the aND gate (aN ₁₎ the output of the aND gate (aN _1), the other input terminal, Iowa gate (OR _2), the moment the second amguho number is selected in the "on A high " signal is applied, and AND gate AN ₁ multiplies two input signals and applies an output " high " signal, that is, a pulse down edge signal, to clock terminal CK of FF (F ₂ ). The output of the FF (F ₂ ) output terminal (Q) becomes a "high" signal, which eventually leads to female A relief is determined and applied to the output control section.

The following describes the operation of the output control section when a signal is output when the password is determined by the decryption section and the user inputs data for driving the external device.

Since the password is determined and the output terminal Q of the FF (F ₂ ) outputs a “high” signal, a “high” signal is applied to one input terminal of the AND gate AN ₂ , and a signal for driving an external device ⑺, i.e. Iowa gate (OR ₃₎ since a "high" output of the AND gate _{(AN 2) (AN 3)} "low" at the output moment "high" on the other input is applied to the terminal AND gate (AN ₂₎ the FF ( F ₃₎ is pulse-down edge signal to the clock terminal (CK) is applied to the FF (F ₃₎ an output terminal (Q) in the "high" signal is output is applied to one input terminal of an electrical AND gate (aN ₃₎ .

Therefore, the AND gate (AN ₃₎ After output, the output of the bar, FF (F ₄₎ to be applied to the clock terminal (CK) of the FF (F ₄₎ is "high" state since the emitted light of the light emitting sensor (LED ₂₎ of The light receiving sensor CDS ₃ is "on" and the external device 외부 is driven.

On the other hand, if the user selects the numeric array plate of the MFC phone so that the output of the OR gate (OR ₄ ) is "high" to drive the external device 7-n, the output of the AND gate (AN ₅ ) is instantaneously ""therefore it is applied to the clock terminal (CK) of the FF (F _n) the output of the FF (F _n)", "the" high to low is the high "signal and eventually driving the external device (7-n).

The following describes the operation of the alarm unit that generates a melody when the external device is driven.

The output of the multi-vibration (MUT) and the frequency through the light receiving sensor (CDS ₂ ) and the external device output control signals (T ₁ , T ₂ , T _n ) are applied to the input terminals of the AND gate (AN ₆ -AN ₈ ), respectively. Therefore, when the external device 구동 is driven, the output of the corresponding AND gate (AN ₆ -AN ₈ ) becomes a "high" signal and is applied to the clock terminal CK of the counter CUT through the OR gate OR ₅ . .

At this time, a "high" signal is output from the output terminal Q ₁ of the counter CUT to turn on the light emitting device LED ₄ so that the light receiving device CDS ₅ is "on" so that the melody is integrated into the speaker SP. And is applied to the reset terminal RE of the counter CUT through the resistor R ₁₀ and the capacitor C ₃ , so that the counter CUT is initialized.

The operation and effect of the present invention operating as described above has the advantage that the user can drive the desired device using the MFC phone.
