Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control device suitable for use in remotely controlling electronic equipment located in a separate room in a home, factory, or the like.

[Conventional technology]

When remotely controlling electronic devices at home, etc., infrared remote control devices are often used. In this method, when the remote control device is operated, a signal corresponding to the operation is output as infrared light, and electronic It is input to the device's light receiving device. The infrared light received by this light receiving device is photoelectrically converted, and data corresponding to the operation is read. As a result, the electronic device performs an operation corresponding to the read data.

In this way, the conventional device uses a light-receiving bag f provided in an electronic device.
Since the f1 (photoelectric conversion device) receives infrared rays, it was not possible to operate electronic devices placed in other rooms.

[Means to solve the problem]

The remote control device of the present invention includes: a first photoelectric conversion means that receives optically transmitted data and outputs an electrical signal corresponding thereto; an identification signal generation means that generates a predetermined identification signal; an addition means for adding the data converted into an electric signal by the photoelectric conversion means and an identification signal; a modulation means for modulating the output of the addition means and outputting it to the power line; and a signal transmitted via the power line. and demodulating means for receiving and demodulating.

A determining means for determining the identification signal included in the signal demodulated by the demodulating means, and a second photoelectric conversion means for converting the data demodulated by the demodulating means into an optical signal in accordance with the determination result of the first determining means. Be prepared.

[Effect]

In the remote control device configured as described above, data optically output using infrared rays or the like is photoelectrically converted and transmitted together with an identification signal via a power line. The data received via the power line is converted back into an optical signal and is input to, for example, an electronic device.

Therefore, it becomes possible to remotely control electronic devices and the like placed in different rooms.

〔Example〕

FIG. 2 is a block diagram illustrating the arrangement of the remote control device of the present invention.

The remote control device 1 has various switches, buttons, etc., and outputs signals (original code signals) corresponding to the operations thereof as infrared rays. This infrared ray is incident on the transmitting/receiving device 2 placed in the same room. Transmitting/receiving sliding devices M3 and 4 having the same configuration as the transmitting/receiving device 2 are also arranged in other rooms (of course, the same room may be used). These transmitting/receiving devices F2 to F4 are each connected to a power line 5.

Electronic devices 6 and 7 to be remotely controlled are placed in the rooms where the transmitting and receiving devices 3 and 4 are placed, respectively.

The transmitting/receiving device i2.3 is configured as shown in FIG. 1, for example.

In the sending/receiving sliding unit w2, the remote control device 1
The infrared rays outputted from the infrared rays are received by a light receiving element 11 (first photoelectric conversion means), and the output thereof is waveform-shaped by a waveform shaping circuit 12 and then supplied to a memory 13 and stored therein. The signal read from the memory 13 is input to the adder 14, where it is added (superimposed) with the ID signal (identification signal) set by the ID setter 15 (identification signal generation means).The output of the adder 14 is modulated. A carrier of a predetermined frequency that is input to the converter 16 (modulating means) and output by one oscillation s17 is subjected to FSX modulation. The output of this modulator 16 is
It is output to the power line 5 via a DC blocking capacitor 18.

On the other hand, the transmitting and receiving device! 3, a signal transmitted via the power line 5 is passed through a capacitor 21 to a demodulator 22 (
demodulation means). The demodulator 22 is supplied with a carrier having the same frequency as the oscillator 17 from the oscillator 23 . After the output of the demodulator 22 is waveform-shaped by the waveform shaping circuit 24, the signal output from the reception ID setter 26 is also input to the 0 discrimination circuit 25 which is input to the discrimination circuit 25 (discrimination means). The output of the 6-discrimination circuit 25 is input to a light emitting element 27 (second photoelectric conversion means) and converted into infrared light.

In addition, sending and receiving sliding! In 2, only the transmission system is replaced!
3 shows only the receiving system, but each of these has a transmitting system and a receiving system in pairs.

Next, its operation will be explained.

Remote control equipment! When a predetermined operation is performed in step 1, an infrared signal (data) corresponding to the operation is output and input to the light receiving element 11. The light receiving element 11 converts the received infrared signal into an electrical signal.

After this electrical signal is waveform-shaped by the waveform shaping circuit 12, it is input to the memory 13 and then stored.

On the other hand, the user operates the ID setting device 15 to set the ID (for example, number 1234) of the electronic device (in the case of the embodiment, the electronic device 6) that the user wants to remotely control. Adder 14 adds the ID set by ID setter 15 and the signal stored in memory 13 and outputs the result to modulator 16 . The modulator 16 performs FSX modulation on the carrier having a frequency of, for example, 200 KHz, which is output from the oscillator 17, using the signal input from the adder 14.

This FSX signal is output to the power line 5 via the capacitor 18.

The signal transmitted through the electric light line 5 is transmitted and received! 3, the signal is input to the demodulator 22 via the capacitor 21. The demodulator 22 receives the carrier (200
The input FSX signal is demodulated based on the frequency (KHz). This demodulated output is input to the waveform shaping circuit 24, and after being waveform-shaped, is input to the discrimination circuit 25.

Sending and receiving bag! 3, the reception ID setter 26
0 where the ID (number 1234) of electronic device 6 is set
The discrimination circuit 25 reads the ID included in the signal input from the waveform shaping circuit 24 and compares it with the ID set by the reception ID setter 26. The read ID is the receiving ID
When the ID matches the ID set by the setting device 26, the discrimination circuit 2
5 outputs the data signal input from the waveform shaping circuit 24 to the light emitting element 27. As a result, from the light emitting element 27,
Infrared light similar to that output by the remote control device 1 is output.

This infrared rays are detected by the light receiving element 6A of the electronic device 6. Therefore, the electronic device 6 is controlled in response to the operation of the remote control device ll.

The signal output to the power line 5 is also input to the transmitter/receiver bag W4, but since a different ID (for example, number 1235) is set in the transmitter/receiver 14, the transmitter/receiver 4 does not output infrared rays. The electronic device 7 having the light receiving element 7A does not operate.

It is also possible to connect the transceiver device 3, 4 directly to the electronic device 6.7 via a cord. However, if you do so, the electronic devices 6 and 7 become transmitting/receiving devices! 3.4. Therefore, if the electronic equipment is controlled via infrared rays as in the above embodiment, electronic equipment configured to be remotely controlled by infrared rays can be
It is advantageous because it can be used as is without any particular modification.

Note that, of course, if the electronic equipment 6 is placed in the same room, the electronic equipment 6 can be directly controlled by the remote control device 1.

〔Effect of the invention〕

As described above, according to the remote control device of the present invention, an optical signal is converted into an electric signal, an identification signal is added, and the signal is transmitted via an electric light line. Electronic devices can be selectively operated.
