Description

Remote Control for Phone

1 is a schematic configuration diagram of an apparatus of the present invention.

2a-2f are detailed circuit diagrams of respective parts of FIG.

The present invention relates to a control device that can be remotely controlled from a remote place by connecting the control objects to the trunk line connected to the telephone, in particular, that a specific password is stored in the control device and correct control is performed through an accurate response. It also relates to a remote control that can be identified.

As a civilization in the modern age, telephones are widely used in most homes, which make up a very good communication network, but are not used for any other function except a telephone line. If it can be used to transmit or receive the control information of household appliances using the pole line for the telephone which constitutes such communication network, it is a very economical benefit because it is not necessary to construct a communication network as a separate control information line. It can be used more abundantly and efficiently. There are many limitations to using a CO line for a telephone.

In other words, the frequency of the transmission information is limited to the frequency band of the telephone, and the signal for the transmission information is limited to the signal of the telephone.

According to the present invention, the user can send the control information to a control device connected to his or her telephone by using a conventional telephone communication network at a long distance, but utilizes it as a control signal by using an exchange signal used in the current telephone communication as it is. A remote control device is provided. Therefore, in the present invention, the user dials his home telephone number at a long distance and then sends a ringing tone generated by the current telephone system to his / her phone. When the call signal is detected, the line of the user's phone is disconnected from the trunk line, and the center part is connected to the trunk line. After that, when the user dials a predetermined password number, for example, 129 or 110, the ceiling of the user's house It is an object of the present invention to provide a remote control device capable of turning on or off lights, headlights, and the like. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIG. 1, in the relationship between the telephone station switchboard to which the apparatus of the present invention is connected and the apparatus of the present invention, the user's telephone B is connected to the remote MFC telephone A through the telephone station switch C in FIG. If the call is selected, the telephone exchange (C) transmits the call signal to the telephone (B) through the telephone line (D) or the trunk line. At the same time, the telephone exchange (C) transmits the call signal to the telephone (A). (B) Tell a ringing back tone to indicate that you are going. When the call signal is sent to the telephone B side, the call signal is also sent to the remote control device E of the present invention connected in parallel to the telephone B. If the on-call signal through the telephone line (D) received in through the central control unit (E _1), the paging signal receiver (E ₆₎ notifies to the common control unit (E ₇₎ and a common control unit (E ₇₎ the line (C Let the central control unit E ₁ be in a response state (rope state) with respect to the telephone line (D).

At this time, according to a predetermined operation method, the common control unit E ₇ causes the voice automatic answering unit E ₉ to pass through the central control unit E ₁ via the line d to the telephone line D with respect to the telephone line D. Responds that the apparatus of the present invention connected to the < RTI ID = 0.0 >

On the telephone A side, the telephone line D is in a looped state and recognizes that the call tone is interrupted, and at the same time, the device E of the present invention connected to the desired telephone B is operated while listening to an automatic voice response. Since it is confirmed that the user sends a complex frequency (MFC) to the dial button of the telephone (A), which is an MFC phone, the user sends a signal by a combination of numbers or symbols that the user specifically specifies.

When the apparatus E of the present invention connected to the telephone B side receives the numerical combination or symbol combination signal of the MFC, the signal is applied to the information receiving unit E ₂ via the central control unit E ₁ , and then subjected to filtering and encoding. The information is converted into a code corresponding to a combination of the original analog numbers and symbols sent by the user and stored in the information storage unit E _{3 in} the order of the received numbers and symbols.

When the combination of numbers and symbols is received and stored, the combination of numbers and memories is applied to the information discriminating unit (E ₄ ) to determine how to control what object the content of the code is to control the information transfer unit (E ₅ ). By sending a signal, the control object F is controlled according to the control content. When a control signal is supplied to the control object F through the information transmitting unit E ₅ , the common control unit is made to inform the common control unit E ₇ that the control signal is supplied to the control object F through the b line of FIG. 1. The audible sound is notified to the signal generator E ₈ that the control object is operated according to the contents of the control signal to the telephone A side.

On the telephone A side, knowing that the desired object has been controlled as desired, all connection states are restored by replacing the telephone state between the telephone A and the telephone B by putting the telephone receiver in place. Here, the control object (F) may be a household appliance such as a fluorescent lamp or a lamp or an electric rice cooker.

However, if necessary, in addition to the basic control method, the telephone (A) is used to call the telephone (B) side to check whether the person who wants to control the control object (F) on the telephone (B) side has the right of right. The procedure (hereinafter referred to as "password transmission and confirmation") may be performed before a control signal consisting of a combination of numbers or symbols is transmitted. In addition, if necessary, the control object F may be informed of the current state of the control object F (hereinafter referred to as "confirmation of goods status") before the control signal is sent to the control object F.

First, the password transmission and confirmation procedure is received by the information receiver E ₂ on the telephone B side when the telephone A sends the password consisting of a combination of numbers and symbols with the MFC push button to the telephone B side. When all the numbers constituting the password are stored in the storage unit E ₃ , it is determined and notified to the common control unit E ₇ whether the password is correct. The common control unit E ₇ generates a signal when the password is correct. (E ₈ ) notifies the telephone A that the password is correct by an audible sound, and if the password is incorrect, the common control unit E ₇ may cause the communication network controller E ₁ to immediately disconnect the connected line.

Referring now to Figures 2 (a)-2 (f), the partial operation of the device and its implementation are described as follows.

In FIG. 2a, a circuit diagram of the central control unit E ₁ of the apparatus of the present invention is shown, wherein lines a and b are connected in parallel to the telephone B and the trunk line D. FIG.

When the user calls the telephone B by dialing his / her home telephone number using the remote telephone A, the telephone exchange of the telephone company will handle the call signal to the telephone B side as if the telephone exchange C handled the normal telephone communication. (I.e., ring tone), and ring tone (i.e. ring back tone) is transmitted to the telephone A side. When such a call signal is applied to the telephone ring circuit 1 composed of a resistor R ₁ , a capacitor C ₁ C ₂ , and a diode D ₁ , D ₂ , the number of the call signals applied to the telephone ring circuit is calculated using a conventional counter. Counted by the call signal receiving unit (E ₆ ) consisting of when the predetermined number of times the user reaches a predetermined signal is generated and applied to the common control unit (E ₇ ).

Then, the relay R _у of the common control unit E ₇ is operated to change the connection state of the contacts Q ₁ and Q ₂ of the relay, so that the telephone B is disconnected from the trunk line, and the apparatus of the present invention is connected to the trunk line O. Is connected to. At this time, it is applied to the common control unit (E _7), the voice automatic response unit (E ₉₎ predetermined applies an address signal to the talk voice signal that was previously set in a voice automatic response unit (E ₉₎ circuit 3 in the speech signal It is sent to the telephone A side. Here, the voice answering unit E ₉ may be configured with a known voice memory device or may be configured with another suitable voice device.

In addition, since the talk circuit 3 is composed of a diode bridge 301 and an amplifier 302 like the known phone talk circuit, a detailed description thereof will be omitted. Therefore, the user who wants to control the remote controller E of the present invention connected to the telephone B side through the telephone A can confirm that the telephone number that he called is correctly connected to the target telephone B. .

Afterwards, in order to avoid the case where the remote controller E connected to the telephone B is not driven, a specific encryption signal may be transmitted using the dial of the telephone A, and the remote controller E may check this. .

Subsequently, when the user transmits a combination of predetermined numbers (for example, fluorescent lamps of 007 and rice cookers of 008) to the remote controller E by using the dial of the telephone A, the information receiver E ₂ receives the central controller ( This signal is received through the sign language circuit 4 composed of the voice transformer of E ₁ ). The coils W ₁ , W ₂ , W ₃ in FIG. 2A have the same configuration as the coil bridge of the ordinary automatic telephone.

In FIG. 2B, the configuration of the information receiving unit E ₂ when the telephone used is an MFC telephone is shown.

The information receiver E ₂ includes a known high frequency filter 5 and a low frequency filter 6 for dividing the received MFC frequency signal into high frequency and low frequency, and the outputs of the high frequency filter 5 and the low frequency filter 6 are It is applied to an encoder 8 composed of a known A / D converter via a noise canceller 7 for removing noise components.

Therefore, the MFC signal transmitted from the telephone A side is converted into binary code (data) by the encoder 8 constituted by the A / D converter and stored in the information storage unit E ₃ . In addition, the outputs of the high frequency and low frequency filters 5 and 6 are supplied to the common control unit E ₇ through the AND gate 2 to indicate that the cipher number is applied to the information receiving unit E ₂ .

In FIG. 2C, it is shown that the configuration of the information storage unit E ₃ is constituted by the auxiliary storage device 9-12, in which the auxiliary storage device 9-12 is constructed according to the number of digits of the cipher number used. The number is determined. That is, in the case of the four-digit code number, four auxiliary storage devices 9-12 are required as shown in FIG. 2C, and each auxiliary memory device may be configured as a digital counter. The receptacle terminal and the clock terminal of the auxiliary storage device 9-12 are connected to the common controller E ₇ .

In FIG. 2d, the information discriminating unit E ₄ is composed of four decoders 13, 14, 15, and 16 and NAND gates 17 and 18. However, this is only one example and the number of NAND gates is shown in FIG. It can be increased or decreased depending on the number of control objects.

If the degree 2d, there is shown the configuration and construction of the information determining unit (E ₄₎ 2 of control when the target substance is connected to the information of the determination section (E _4). That is, the decoders 13, 14, 15, and 16 of the information discriminating unit E ₄ replace the received MFC signal with the original decimal signal and connect the decimal output to the NAND gates 17 and 18. Determine and supply to the information transmitting unit (E ₅ ). If the input information is wrong, no signal is applied to the information transmitting unit. This state is applied to the common control unit E ₇ by line a.

If there is an input signal but the output of the information discriminating unit E ₄ is not present, the common control unit E ₇ may stop the operation of the entire apparatus or transmit a signal to the telephone A side that the signal is incorrectly applied. In FIG. 2D, four decoders 13, 14, 15, and 16 are used when the cipher number is four digits, but when the cipher number used is three digits, FIG. The auxiliary storage device of the information storage unit E ₃ shown in Fig. 3 is used, and only three decoders in Fig. 2d can be used. In addition, the NAND gates 17 and 18 increase or decrease according to the number of control objects F. As shown in FIG. That is, one control object F is controlled per one NAND gate. If multiple control objects F may be turned on and off simultaneously, only one NAND gate will be needed. In addition, in FIG. 2e, it is shown that the information transmitting unit E ₅ is composed of a plurality of relays 17 'and 18', current sensors 19 and 20, power amplifiers 21 and 22, and the like.

The relays 17 'and 18' operate when the output signal of the information discriminating unit E ₄ is applied, and the current detectors 19 and 20 operate the relays 17 'and 18' so that the control object F operates. The confirmation signal is transmitted to the common control unit E ₇ .

That is, when the current detectors 19 and 20 sense current, the relays 17 'and 18' and the control object F are in operation. When the current detectors 19 and 20 do not sense the current, the relays 17 'and 18' and the control are controlled. It is to check the state in which the object (F) does not work. Sometimes it is used to check the operating status of the control object (F). Also, in FIG. 2F, the configuration of the common control unit E ₇ is shown.

When an output is generated from the call signal receiving unit E ₆ , an output of the amplifier 23 is generated to operate the relay R _у of the control central unit E ₁ . In addition, the output of the AND gate _{2 of the} information receiving unit E ₂ and the line a of the information discriminating unit E ₄ are input to the NAND gate 24 so that there is an output of the AND gate 2 (high). In spite of this, when there is no output from the information discriminating section E ₄ , the output of the NAND gate 24 becomes a "high" state and is applied to the signal generating section E ₈ . That is, the phone A is informed that an incorrect password number has been input. At the same time, if necessary, it is possible to separate the device of the present invention from the telephone line D by installing the blocking part 31 surrounded by a dotted line.

That is, when the output of the NAND gate 24 becomes high, the output of the amplifier 29 is generated to drive the relay 30 to turn off the relay 30 contact point connected to the trunk lines a and b.

Such a blocking part 31 can also be installed as needed. In addition, when the output of the gate 24 becomes "high", the signal applied to the input I ₀ of the binary counter 26 through the inverter 25 becomes "low" and the binary counter 26 counts the coefficients. You will not. If the AND gate _{2 of the} government receiver E ₂ and the line a of the information discriminating unit E ₄ are all "high", i.e. if they are the correct cipher numbers, the output of the NAND gate 24 is "low". The signal generator E ₈ is not activated, and a "high" signal is applied to the input I ₀ of the binary counter 26 through the inverter 25 once.

As described above, when the number of digits of the cipher number is four digits, the outputs D ₄ to D ₁ of the binary counter 26 become (0101), and the output of the AND gate 27 becomes "high" so that the information storage part ( E ₃ ) the entire secondary storage device (9-12) is re-received to accept the next cipher number.

In addition, the output of the AND gate _{2 of the} information receiver E ₂ (indicating that the password number is input), the line (a) of the information discriminating unit E ₄ (indicating that the password number is correct), and the information transmitting unit E ₅ ) If the state of line b (indicative of the operating state of the control object F) is "high", the output of the NAND gate 28 is in a "low" state, and the signal generator E ₈ receives a signal. If not generated or a predetermined signal can be generated to allow normal operation on the telephone A side and any one of the inputs of the NAND gate 28 is "low", the output of the NAND gate 28 is "high". Since a specific signal is generated in the signal generator E ₈ and transmitted to the telephone A side through the talk circuit 3 of the control center E ₁ , the user of the telephone A needs a desired object F. You can check whether it worked as it should.

In order to control the remote control object through the telephone line according to the present invention, the control object of the home (the phone B side) where no one is going out (to the phone A side) is controlled. Some examples are:

Case 1

Case 2

Case 3

Note: In Cases 2 and 3, the sequence of operations 2 to 4 may be as follows.

As described above, according to the present invention, it is possible to remotely control home appliances connected to one's own home telephone, even at a distance, and to use a telephone network already installed without using a separate communication line or a communication network. Installation is very easy since it is connected to the trunk line.
