Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a telephone set, and particularly to one equipped with an infrared remote control device for remotely controlling a plurality of electrical devices.

<Prior art and its problems> In recent years, infrared remote control devices are frequently used to remotely control home appliances.

In this case, the home appliance is equipped with an infrared receiving device and an infrared transmitting device is installed at a location separate from the home appliance, but if multiple home appliances that are remotely controlled by infrared rays are placed adjacent to each other, In order to prevent malfunctions caused by receiving infrared signals from the infrared transmitting device, the infrared receiving device of each home appliance receives the infrared signal corresponding to the identification code assigned to it, and also performs an operation to indicate the operating status. The home appliance is configured to operate when receiving an infrared signal corresponding to a command signal. Therefore, if you want to remotely control each home appliance, you will need an infrared transmitter for each home appliance, and the problem is that you cannot remotely control multiple home appliances with one infrared transmitter. There was.

In addition, in recent years, devices have been developed that remotely control home appliances installed in the home from outside the home using a telephone, or in this case, the home telephone commands the operation from a telephone outside the home. When a signal is received, a circuit must be installed inside the phone to control the relay circuit attached to each home appliance, and wiring from this circuit to each relay is required.
There was a problem that the wiring work was troublesome.

<Means for Solving the Problems> In order to solve each of the above-mentioned problems, the present invention provides an infrared light emitting section provided in the telephone main body and a signal supplied to the telephone main body through a telephone line or A code signal that identifies at least one of the plurality of electrical devices to be controlled and an operation data signal that specifies the operating state of the identified electrical device are generated in response to a signal generated by operating an operation button on the main body. The present invention includes a signal generation section that generates a signal, and a light modulation section that is configured to optically modulate the generated coat signal and operation data signal and supply the modulated signal to the infrared light emitting section.

<Operation> According to the present invention, the signal generation section generates a code signal and an operation data signal in response to a signal from a telephone line or a signal generated by operating an operation button on a telephone. The light modulation section optically modulates the coat signal and the operation data signal and supplies the modulated signals to the infrared light emitting section. The infrared light emitting unit transmits an optical signal that includes a code signal and an operation data signal to each electrical device that is to be controlled. The electric device receives a data signal, or operates in accordance with the operation data signal, or the electric device matches the code signal assigned to itself and the received code signal.

Effects> As described above, according to the present invention, it is possible to remotely control a plurality of electrical devices from one telephone, and therefore it is possible to centrally manage each electrical device. Further, no wiring is required between each electrical device and the telephone.

<Example> In this example, as shown in FIG. 2, five home appliances 2a to 2e are remotely controlled by an infrared signal from an infrared light emitting unit 6 provided in one telephone 4. This infrared signal is a dial pulse tone signal generated by operating the operation button of the external telephone 10 transmitted via the exchange 8 or a dial pulse tone signal generated by operating the operation button 12 of the telephone 4. Generated based on pulse tone signals.

That is, as shown in FIG. 1, a dial pulse tone signal is supplied to the telephone set 4 from the telephone terminal via the exchange 8, or a dial pulse tone generator is activated by operating the operation button J2 of the telephone set 4. 14 or the dial pulse tone signal generated is sent to the remote control tone signal discriminator 1.
6. In addition, the dial pulse tone signal is
It consists of a signal that designates any one of the home electrical appliances 2a to 2e, and a signal that designates the operation that the designated home electrical appliance is to perform on a regular basis.

The remote control tone signal discriminating section 16 distinguishes the dial pulse tone signal from other signals such as the voice signal from the exchange Ja, 8 or the transmitter/receiver section 18, and supplies it to the 1 determining section 20. The determination unit 20 determines the home appliance designation signal from among the dial pulse tone signals, and selects the one corresponding to the home appliance designation signal from among the coat pulse trains assigned to each of the home appliances 2a to 2e. The coating is generated in the coat generating section 22. Further, the determination unit 20 determines the operation designation signal among the dial pulse tone signals, and generates a data pulse train for operating the home appliance designated by the home appliance designation signal to the data pulse generation unit 20.
to occur.

These coat pulse train and data pulse train are supplied to the pulse train generating section 26, or the pulse train generating section 26 generates a pulse train according to them and supplies it to the optical modulating section 28. The light modulation section 28 causes the infrared light emitting section 6 to blink in accordance with the pulse train to generate a light modulation signal.

This optically modulated signal is received by an infrared receiving device (not shown) provided in the home appliances 2a to 2e, demodulated into a coat pulse train and a data pulse train, and assigned to the self among the home appliances 2a to 2e. The coat pulse train and the demodulated pulse train that match each other perform an operation according to the data pulse train.

An example of a pulse train provided by the pulse train generator 26 to the optical modulator 28 is shown in FIGS. 3(a) and 3(b). The pulse train is
As shown in Figure (a), a leader pulse, a subsequent coat pulse train, an inverted coat pulse train that is an inverted code pulse train, a data pulse train, and an inverted data pulse train that is an inverted data pulse train are generated in this order. in,
As shown in FIG. 6(b), the leader pulse generates a pulse with a period T (for example, about 26.3 seconds or 25 seconds) for a time t, and then for a time t. It is formed by not generating pulses during this period. Furthermore, in the code pulse train, inverted code pulse train, data pulse train, and inverted data pulse train, pulses with a period T are generated for a time t, as shown in FIG. represents the binary number "0", and the period T
The binary number rlJ is represented by generating a pulse for a time t, followed by no pulse for a time t3. That is, a binary number is represented by pulse position modulation.

In addition, other examples of pulse trains provided by the pulse train generator 26 include a leader pulse, a code pulse train,
A data pulse train is generated in sequence, followed by a leader pulse again, followed by an inverted leader pulse,
There is also one that sequentially generates a reverse coating pulse train. Each leader pulse, code pulse train, data pulse train, inverted coat pulse train, and inverted data pulse train is configured in the same manner as in the previous example.

In addition to the code pulse train and the data pulse train, the inverted code pulse train and the inverted data pulse train are formed because if an infrared signal modulated only by the coat pulse train and the data pulse train is transmitted to each home appliance, each home appliance The code pulse train and data pulse train demodulated by this method have errors or are susceptible to aging, and an inverted code pulse train and an inverted data pulse train are formed, which are also optically modulated and transmitted, and these are used to correct errors. It's for a reason.
