Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a voice control device that controls electrical equipment using voice.

The applicant of this patent has already proposed in Japanese Patent Application No. 55-62136 a device that can remotely control the ON/OFF of gate lights, coolers, electric kettles, etc. using telephone lines. The outline is shown in Fig. 1. In the figure, 1 is an answering machine connected to telephone line 2,
Existing answering machines will be used. 3 is an audio circuit connected to the telephone line 2 via the answering machine 1 and controlling the operation of the answering machine 1;
The main components are a speech recognition section 4 and a speech synthesis section 5. Reference numeral 6 indicates electrical equipment such as a gate light, cooler, electric kettle, etc., which is controlled by commands from the audio circuit 3. Specifically, ON/OFF control of a power switch 8 between the electrical equipment 6 and the power source 7 is controlled. This applies. The above-mentioned answering machine 1 includes a transmitter/receiver 9,
A control switch 10 is provided which connects and disconnects the telephone line 2 and the audio circuit 3 in response to commands from the transmitter/receiver 9. Furthermore, a transmitter/receiver 11 is connected to the transmitter/receiver 9. It's on.

When a family member wants to turn on or off a gate light or an air conditioner in his/her home from outside, he/she calls his/her home from his/her home, closes the control switch 10 based on the function of the answering machine 1, and listens to the family's voice. For example, transmit "light on" to the voice recognition unit 4, compare it with the registered voice registered in advance, and when it recognizes "light on" as a result, turn on the power switch 8 and turn on the power corresponding to the power source 7 and the gate light. Connect with device 6. At the same time, when "Light On" is correctly recognized, the speech synthesis section 5 emits "Light On" to confirm to the family member who is away from home via the telephone line 2 that the "Light On" has been correctly recognized.

Such devices can be used to turn on various electrical devices from outside,
Since OFF control is possible, it is considered to be extremely useful for households where the user is often away.

Reference numeral 8 denotes a voice synthesis device that transmits the operation status of the program timer 23 to the handset 22.

FIG. 3 shows the internal configuration of the program timer 23 described above, which includes a control section 30 to which a recognition result signal from the voice recognition device 20 is applied, a clock circuit 31 that performs a timekeeping operation, and a signal obtained from the voice recognition device 20. It consists of a time memory 32 for storing time information, and a parallel-to-serial conversion circuit 33 for deriving a control signal from the control section 30 to the transmitting circuit 24. still,
Associated with the clock circuit 31 are a crystal oscillator 34 that generates a basic pulse for timekeeping operation and a correction switch 35 that adjusts the time.

Further, FIG. 4 shows the configuration of the above-mentioned transmitting circuit 24 and receiver 26, and the transmitting circuit 24 includes a local oscillator circuit 40 having a frequency much higher than the commercial frequency, and a local oscillator circuit 40 having a frequency much higher than the commercial frequency. It consists of a modulation circuit 41 that modulates the control signal from the program timer 23 according to the emitted signal, and an AC
Its modulated output is sent out on line 25. The receiver 26 also includes a demodulation circuit 44 connected to the AC line 25 via a capacitor 43, an RS flip-flop 45 that operates based on the control signal demodulated by the demodulation circuit 44, and a number of controlled devices based on the control signal. a number register 46 that selects and stores the number, a number switch 47 that manually sets the number of the controlled device, and a comparison circuit 4 that compares the stored contents of the number register 46 with the set value of the number switch 47.

and the AC line 25 via its relay contact 51.
and an AC outlet 52 connected to the AC outlet 52.

Next, let us consider a case where the external telephone 12 connected to the handset 22 via the telephone line 21 is used to control ON/OFF of an electric device installed indoors, for example, an air conditioner. Moreover, at this time, we will discuss the case where not only ON and OFF but also ON and OFF times are reserved. For example, at this time, if the device number of the cooler is number 2, that is, the cooler is connected to the second AC outlet 52, the number switch 47
is also set to No. 2 by manual operation.

A voice obtained from the transmitter/receiver 22 , for example, "Cooler, ON, 1, 7, 3, 0," is recognized by the voice recognition device 20 and stored in the time memory 32 via the control section 30 of the program timer 23 . And normally this "cooler, ON, 1, 7, 3,
0'' is recognized and stored, a synthesized voice to that effect is generated from the voice synthesizer 28 and transmitted to the external telephone 1 via the handset 22 and the telephone line 21.
2 and prompts the person who made the call to confirm.

On the other hand, the clock circuit 31 measures the current time,
The momentary time is output to the control section 30. The time of this clock circuit 31 and the time information of the time memory 32 are constantly compared in the control unit 30, and now at 5:30 pm, the time information of the time memory 32 and that from the clock circuit 31 match. , the control signal "Cooler ON" is converted into a serial signal via the parallel-to-serial conversion circuit 33 and applied to the transmitting circuit 24. In this oscillator circuit 24, "cooler ON" is modulated with a high frequency from the local oscillator circuit 40.
It is sent out to the AC line 25.

On the other hand, in the receiver 26 connected to the AC line 25, the control signal constantly obtained via the AC line 25 is demodulated by the demodulation circuit 44, and the control signal is input into the number register 46 each time. However, unless the contents of the preset number switch 47 match, the subsequent operation will not be performed. However, at this time, as mentioned above, the cooler is
Since it is connected to the second AC outlet 52,
Setting value of number switch 47 and number register 46
The comparison circuit 48 detects the match, the D-type flip-flop 49 enters the set state, current flows through the relay coil 50, its contact 51 turns on, and it is connected to the outlet 52. The cooler is energized.

Incidentally, in the above embodiment, remote control from outdoors using the telephone line 21 was explained, but it is also possible to directly input the voice signal from the microphone to the recognition device 20 without using the handset 22. It is possible.

As is clear from the above description, the present invention modulates a control signal recognized by a speech recognition device.
Since it is placed on an AC line and the control signal is demodulated on the electrical equipment side to control the electrical equipment, it is possible to remotely control electrical equipment installed indoors using voice, and its usefulness is remarkable. be.
