Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control method for controlling household equipment such as an air conditioner and a lighting device from a telephone terminal outside a house.

[0002]

2. Description of the Related Art A demand for driving an air conditioner at home before returning home to a comfortable state, and a demand for ventilating a home from outside when leaving home for a long time. In order to deal with this, a remote control method using a telephone line has already been performed. It is known that this remote control method is performed by, for example, a remote control device as shown in FIG. Subscriber line exchange (hereinafter referred to as
A telephone 3 is connected to a telephone line 2 drawn into the house from an exchange 1, and a remote control device 7 is connected to the telephone line 2.
0 is branch connected. The remote control device 70 includes an incoming call detection unit 72 for detecting a call signal, a DC loop formation unit 74 for forming / opening a DC loop of a line, and a line I for exchanging device control information with a telephone voice band signal. /
It comprises an F unit 75, a control unit 76, and a device I / F unit 78 for exchanging control signals with the house equipment 79.

[0003] In the case of remote control from outside, a telephone call is first made to a home. Then, after the polarity of the telephone line 2 is reversed,
A call signal is sent, and the incoming call detection unit 72 detects this.
If the telephone 3 is not off-hook and a DC loop is not formed, the call signal continues, and the DC loop forming unit 74 forms a DC loop after the detection of the call signal has continued for a certain period of time. As a result, an incoming call response is sent to the local exchange 1, and a communication line is established. A person who performs remote control performs a DT by performing a push button operation according to a personal identification number for performing operation authentication from the telephone terminal or the control content of the device.
Transmit the MF signal. On the remote control device 70 side, the line I /
The DTMF signal is demodulated by the F unit 75 and transmitted to the control unit 76. When the received personal identification numbers match, the control unit 76 instructs a control signal corresponding to the control content to be output from the device I / F unit 78 to the household equipment 79, and remote control is performed.

[0004] Recently, many homes are equipped with a telephone which has an answering machine function and automatically answers the telephone. In such a case, the waiting time until the DC loop forming unit 74 forms the DC loop is shorter than the waiting time from when the transmission of the calling signal is started until the telephone 3 automatically answers and forms the DC loop. Is set longer, the telephone 3 is preferentially established with the telephone line. In such a state, remote control is possible by monitoring the DTMF signal in the line I / F unit 75.

[0005] However, in the above-mentioned method, even if a third party makes a call from any of the telephone terminals, the remote control device becomes incapable of inputting a personal identification number. While transmitting a voice message, there is a problem in ease of use that a DTMF signal may not be correctly received.

As a solution to these problems, there is a method of using information of a calling telephone number transmitted from an exchange prior to a call signal. That is, the number of the telephone terminal that performs remote control is registered in the remote control device in advance,
Only when the incoming telephone number is received at the time of the incoming call and this matches the registered number, the remote control can be performed by the remote control device, not the telephone, by establishing the communication line and exchanging the control signal. .

Must be set for notifications. However, if the home telephone is set to reject incoming calls or answer by the answering machine function when the other party does not notify the calling telephone number, it becomes impossible to make a direct call to home. There was a problem that.

The present invention solves such a conventional problem, and provides a remote control method capable of realizing easy-to-use and reliable remote control without obstructing services related to display of a telephone number of a telephone. It is intended to provide.

This embodiment will be described on the assumption that a public telephone calling number notification service adopted by Nippon Telegraph and Telephone Corporation is used. Before describing the embodiment of the present invention, the flow of the calling telephone number notification service will be described. FIG. 2 shows a connection operation sequence described in "Interface of Information Notification Service in Telephone Network -Information Notification Service Before Communication-" (November, 1997) issued by Nippon Telegraph and Telephone Corporation. Prior to the normal call signal, the local exchange notifies the called party of the calling telephone number. In transmitting the calling telephone number, the subscriber line exchange (hereinafter, abbreviated as "exchange") first reverses the polarity of the line between the telephone lines (L1, L2), and then activates the information receiving terminal activation signal (activation signal, 15 Hz or more). 20Hz or less, 75V
rms, sound for 0.5 seconds, stop for 0.5 seconds). The information receiving terminal activated in this way returns a response signal (primary response signal) to the exchange by forming a DC loop. The exchange sends the calling telephone number by modem signal,
The information receiving terminal releases the DC loop when the reception is completed. After that, the connection operation sequence becomes the same as that of the normal incoming call. (Embodiment 1) FIG. 1 shows an example of a block configuration of a remote control device for performing a remote control method according to the present invention. A telephone 3 is connected to a telephone line 2 drawn into the house from the subscriber line exchange 1, and a remote control device 10 is connected to this telephone line 2 by branch connection. The remote control device 10 includes an incoming call detection unit 12 that detects an activation signal and a call signal, and an outgoing telephone number receiving unit 13 that receives a modem signal of the outgoing telephone number.
And a DC loop forming unit 14 for forming / opening a DC loop of the line to send out a response signal of a primary response signal, a transmission telephone number reception completion signal, and a secondary response signal, and a signal of a telephone voice band. Line I / for exchanging device control information
F unit 15, control unit 16, storage unit 17 for storing the outgoing telephone number registered to receive remote control and the actually received outgoing telephone number, and housing equipment 19
And a device I / F unit 18 for exchanging control signals with the device. The telephone 3 has a calling telephone number receiving function, and it is assumed that the telephone 3 transmits the primary response signal (DC loop formation) and the reception completion signal (DC loop break).

While the DC loop is formed by the telephone 3, the modem signal of the calling telephone number is transmitted to the remote control device 1.
A method of receiving at 0 will be described. FIG. 3 is a schematic diagram showing an example of a circuit configuration of a portion related to a telephone line. The circuit shown on the upper side in FIG. 3 is impedance-matched with a telephone line at 600Ω by a transformer 22a and a terminating resistor 23a. In a normal standby state, the DC loop forming switch 21 connected to the incoming call detection circuit 20 is turned off.
It is F, and the DC loop of the remote control device 10 is disconnected. The secondary side is input to a modem 25 for demodulating a device control signal via an amplifier 24a. On the other hand, the circuit shown on the lower side in FIG.
It is terminated with an impedance sufficiently larger than 00Ω, and the line (L1, L2) is DC-separated by the capacitor 27. The secondary side is input via an amplifier 24b to a modem 26 for demodulating the signal of the calling telephone number.
As is clear from FIG. 3, the circuit for receiving the lower calling telephone number is always connected to the telephone line 2 with high impedance, and the DC loop forming switch 21 is turned on.
Reception is possible regardless of / OFF.

In the case of remote control from outside, first, a call is made to a home. Then, after the polarity of the telephone line 2 is inverted, an activation signal is sent, and the incoming signal detection unit 12 detects this. After the telephone 3 sends out the primary response signal, the outgoing telephone number receiving section 13 receives the outgoing telephone number signal from the local exchange 1. If the received telephone number matches the telephone number registered in the storage unit 17, the fact that there is an incoming call from this number is stored in the storage unit 17. further,
If the outgoing telephone number received this time matches the previously received outgoing telephone number, the incoming call detecting unit 12 detects a call signal transmitted from the local exchange 1 and forms a DC loop by the DC loop forming unit 14. By doing so, a communication line for transmitting a secondary response signal is established. A person who performs remote control inputs a password from a telephone terminal. The line I / F unit 15 receives the DTMF signal corresponding to the password, and
When a match is confirmed, the following DTMF signal is accepted as a control command, and a corresponding control signal is output from the device I / F unit 18 to the housing equipment 19 to perform remote control. Upon receiving the control command signifying the end of the remote control, the DC loop forming unit 14 sends a disconnection signal to release the communication line and return to the standby state.

FIG. 4 is a flowchart showing the operation of the remote control device 10 described above. Step S1
After detecting the polarity inversion in step S2, it is determined in step S2 whether the incoming signal is an activation signal or a calling signal. Since the start signal has a one-second cycle of 0.5-second ringing and 0.5-second ringing stop, the calling signal has a three-second cycle of one-second ringing and two-second ringing stop, so that it is possible to distinguish them. In the case of the activation signal, the process proceeds to step S3 to receive the subsequent calling telephone number. In the following steps S4 and S5, if the registered telephone number matches and the previously received telephone number matches, a call signal is detected in step S6, and a DC loop is formed in step S7. Sends a secondary response signal to establish a communication line. Then, after receiving the personal identification number and the device control information in step S8, when the termination command is received in step S9, the DC loop is cut off in step S10 and the process is terminated.

As described above, the remote control device 10 is used only when two consecutive calls are received from the registered telephone terminal.
By establishing a communication line to the telephone, the remote control can be reliably performed without the remote control device 10 responding to the incoming call for the purpose of the communication.

In the present embodiment, the communication line to the remote control device 10 is established when there is a continuous incoming call from the same registered telephone terminal. However, the present invention is not limited to this. Conversely, it is also possible to control so that the remote control device 10 does not respond only when there is a continuous incoming call from the registered telephone terminal, but establishes a communication line with the telephone 3.

Further, in the present embodiment, when an incoming call is received, it is checked whether or not it is the same as the outgoing telephone number in the previous incoming call. The outgoing telephone numbers for a plurality of incoming calls may be stored in the storage unit 17 to check whether any of the outgoing telephone numbers match.

Further, in the present embodiment, the DTMF signal is used for exchanging the personal identification number and the device control command. However, the present invention is not limited to this, and the same modem signal used for notifying the calling telephone number is used. Other signal formats can also be used.

Further, in the present embodiment, the remote control device 10 and the telephone 3 are installed in a branch connection in parallel, but the present invention is not limited to this. It is also possible to adopt a circuit configuration in which the devices are installed in series and connection / disconnection with a line is controlled by a remote control device.

Further, in the present embodiment, the circuit shown in FIG. 3 is used to receive the signal of the calling telephone number irrespective of the formation / non-formation of the DC loop in remote control device 10, but the present invention is not limited to this. Instead, a high-impedance loop is formed by installing a series circuit of a capacitor and a resistor in parallel with the DC loop forming switch 21, and a single transformer receives both the outgoing telephone number and the device control signal. It is also possible to use

Further, in the present embodiment, the remote control device 10 unilaterally receives the device control information. However, the present invention is not limited to this, and data representing the operation status of the device is transmitted to the telephone terminal side. May be notified.

Even when a DTMF signal cannot be directly transmitted from a terminal such as when using a digital cellular phone terminal, remote control is performed by using a command or service that is converted into a DTMF signal and transmitted. Is possible. (Embodiment 2) FIG. 1 shows an example of a block configuration of a remote control device according to the present embodiment. The basic operation is the same as that of the first embodiment, and only different points will be described.

The telephone number received at the time of the incoming call is stored in the storage unit 17.
In the case where the telephone number matches the telephone number registered in the telephone number, the fact that there is an incoming call from this number and the time of the incoming call are combined and stored in the storage unit 17 as an incoming call record. The control unit 16 periodically checks the incoming call record, and deletes a record in which a predetermined time (Ti) has elapsed after the incoming call. And
If the incoming telephone number received this time coincides with the recorded outgoing telephone number, the incoming call detecting unit 12 detects a call signal transmitted from the local exchange 1, and the DC loop forming unit 14 executes the DC loop forming unit 14. Is formed, a secondary response signal is transmitted to establish a communication line.

FIG. 5 is a flowchart showing the operation of the remote control device 10 described above. Step S1
After detecting the polarity reversal in step S1, it is determined in step S12 whether the incoming signal is an activation signal or a calling signal. Start signal is 0.5
Since the ringing signal has a 1-second period of 0.5 seconds and the stop of 0.5 seconds, and the calling signal has a 3-second period of 1 seconds and 2 seconds, the distinction is possible. In the case of the activation signal, the process proceeds to step S13 to receive the subsequent calling telephone number. Next steps S14, S
In step S15, if the telephone number matches the registered telephone number and there is an incoming call from the same telephone terminal within a predetermined time (Ti) in the past, after detecting a call signal in step S16, a DC loop is established in step S17. It forms a secondary response signal and establishes a communication line. Then, after receiving the personal identification number and the device control information in step S18, when the termination command is received in step S19, the DC loop is cut off in step S20 and the process is terminated.

As described above, by establishing a communication line to the remote control device 10 only when there are two incoming calls from a registered telephone terminal within a predetermined time, after the predetermined time has elapsed, Means that when a call is made from a registered telephone terminal for a call, the remote control device 10 will not respond to an incoming call for the purpose of the call, and the second call will be made within a predetermined time. Remote control can be performed.

In this embodiment, the communication line is established when two calls are received from the same registered telephone terminal within a predetermined time. However, the present invention is not limited to this. It is also possible to control so that the remote controller does not respond only when the condition is satisfied, but establishes a telephone line with the telephone.

Also, in combination with the configuration of the first embodiment, control is performed such that a communication line is established with a remote control device or a telephone at home only when the received call matches the last outgoing call within a predetermined time. Is also possible.

Further, in the present embodiment, when an incoming call is received, it is checked whether or not the incoming telephone number matches the outgoing telephone number in the previous incoming call. The outgoing telephone numbers for a plurality of incoming calls may be stored in the storage unit 17 to check whether any of the outgoing telephone numbers match.

In this embodiment, a DTMF signal is used for exchanging a password and a device control command. However, the present invention is not limited to this. For example, the same modem signal used for notification of a calling telephone number may be used. Other signal formats can be used.

Further, in the present embodiment, the remote control device 10 and the telephone 3 are installed in a branch connection in parallel. However, the present invention is not limited to this. Install in series and connect with line /
It is also possible to adopt a circuit configuration in which cutting is controlled by a remote control device.

Further, in the present embodiment, the circuit shown in FIG. 3 is used to receive the signal of the calling telephone number irrespective of the DC loop formation / non-formation in the remote control device 10, but the present invention is not limited to this. Instead, a high-impedance loop is formed by installing a series circuit of a capacitor and a resistor in parallel with the DC loop forming switch 21, and a single transformer receives both the outgoing telephone number and the device control signal. It is also possible to use

Further, in the present embodiment, the remote control device 10 unilaterally receives the device control information. However, the present invention is not limited to this, and data representing the operation status of the device is transmitted to the telephone terminal side. May be notified.

Even when a terminal cannot directly transmit a DTMF signal, such as when using a digital cellular phone terminal, remote control is performed by using a command or service that is converted into a DTMF signal and transmitted. Is possible. (Embodiment 3) FIG. 6 shows another example of the block configuration of the remote control device according to the present embodiment.

The outgoing telephone number receiving section 33 receives the outgoing telephone number information from. If the received telephone number matches the telephone number registered in the storage unit 37, the fact that there is an incoming call from this number is stored in the storage unit 37, and the subscriber line is followed by the outgoing telephone number information. A call signal sent from the exchange 1 is monitored by the incoming call detection unit 32. If the calling signal is cut off without the telephone line being established in response to the secondary response and the telephone line is established, it is recognized that the call is for remote control, and the line is switched by the line switching unit 40 to the DC loop forming unit 34 side. Connect to Then, a DC loop is formed, and the dial-up signal transmission unit 41 dials the telephone number of the transmission source stored in the storage unit 37 and calls back.

The outgoing telephone number receiving section 53 receives the outgoing telephone number information. When the received telephone number matches the telephone number registered in the storage unit 57, when a call signal transmitted subsequently is detected, the line is connected by the line switching unit 60 to the DC loop forming unit 54 side. , Forming a DC loop to establish a communication line. The line I / F unit 55 receives the DTMF signal corresponding to the input of the personal identification number, and after confirming the coincidence with the control unit 56, accepts the subsequent DTMF signal as a control command, and receives the corresponding control signal from the device I / F unit 58. The data is output to the housing equipment 59 and remote-controlled. When a command for a request to establish a line with the telephone 3 for a telephone call is received, the telephone 3 is called by the pseudo incoming call signal generation unit 61 in the same procedure as that performed by the exchange 10, and the telephone 3 responds to the call signal. At the timing, the line switching unit 60
Is switched to the telephone 3 side.

FIG. 9 is a flowchart showing the operation of the remote control device 50 described above. Step S5
After detecting the polarity inversion in step 1, it is determined in step S52 whether the incoming signal is a start signal or a calling signal. Start signal is 0.5
Since the ringing signal has a 1-second period of 0.5 seconds and the stop of 0.5 seconds, and the calling signal has a 3-second period of 1 seconds and 2 seconds, the distinction is possible. In the case of the activation signal, the process proceeds to step S53, and the subsequent outgoing telephone number is received. If the telephone number matches the registered telephone number in the next step S54, the telephone line is formed in response to the calling signal in steps S55 and S56. In step S57, the personal identification number and the device control information are received. If the request in step S58 is a connection request to the home telephone, a series of operations (steps S61 to S66) for inverting the polarity and transmitting a call signal to the telephone 3 are performed. Then, after confirming that the telephone 3 makes a secondary response in step S67, the line is switched to the telephone 3 in step S68. If it is determined in step S58 that the request for connection to the home telephone has not been made, after confirming that the remote control input has been completed in step S59, a disconnection signal is transmitted in step S60 to disconnect the DC loop.

As described above, when the connection request to the telephone 3 at home is received, the remote control device 50
, And by establishing a communication line with this, remote control can be reliably performed without impairing the function of the call.

In these embodiments, a case has been described in which a telephone line for remote control and a telephone line are provided, but non-remote control such as a facsimile telephone line is used in place of telephone telephone calls. It is also possible to use a telephone line for communication.

[0051]

As is apparent from the above embodiment, the invention according to claim 1 receives the calling telephone number after detecting an activation signal indicating the calling telephone number notification transmitted from the local exchange. , The outgoing telephone number in the current incoming call only if the received outgoing telephone number matches the telephone number registered in advance and either the outgoing telephone number in the previous incoming call or the outgoing telephone number in the recent multiple incoming calls In response to a call signal detected subsequently, any one of a predetermined telephone line for remote control and a telephone line for non-remote control is established.

This makes it possible to connect a remote control communication line only for a call intended for remote control while normally connecting to a non-remote control communication line such as a telephone. Remote control can be reliably performed without affecting. Furthermore, since remote control is accepted only from a telephone terminal whose number has been registered in the remote control device in advance, the reliability in security is improved, and furthermore, the interval of the arrival time corresponding to these coincident outgoing telephone numbers is predetermined. By adding the condition that the value is within the value, the reliability in security is further improved.

When the telephone which branches the remote control device does not have the answering machine function, the remote control device does not respond to a call from a third party who does not intend to perform remote control. It does not give the uncomfortable feeling of saying, "I can't leave a message even though the phone is connected."

Further, there is no need to exchange a remote control signal within a limited time during which a telephone having an answering machine function establishes a communication line, and the remote control device takes the initiative in establishing and controlling the line. Since opening can be performed, remote control can be performed reliably.

Also, it is difficult for a remote control device to answer a call from a third party who does not intend to perform remote control before the automatic answering function of the home or answering machine answers the call so that a call cannot be made. It does not occur and is easier to use.

In addition, by a simple procedure such as making a call twice in a row, it is possible to establish a telephone line with a telephone or a remote control device that does not normally receive a call at a registered telephone terminal. Easy-to-use remote control that is compatible with both can be performed.

According to a third aspect of the present invention, the calling telephone number is received after detecting an activation signal indicating the calling telephone number notification sent from the subscriber line exchange, and the received calling telephone number is registered in advance. In response to a call signal detected subsequently to the outgoing telephone number in the current call only if it matches the telephone number and either the outgoing telephone number in the previous incoming call or the outgoing telephone number in the most recent incoming calls. Establish a prescribed telephone line, either a predefined telephone line for remote control or a telephone line for non-remote control, the received outgoing telephone number matches the telephone number registered in advance, and Detects the outgoing phone number of the current incoming call only if it does not match any of the outgoing phone number or the outgoing phone numbers of recent multiple incoming calls It is intended to establish a different telephone line than said prescribed communication line in response to the call signal.

Thus, when remote control is performed from a registered telephone terminal, it is possible to directly establish a line with the remote control device, so that operability is greatly improved. A communication line with a telephone can be reliably established.

In addition, since a call line can be established with a telephone or a remote control device that does not normally receive a call at a registered telephone terminal by a simple procedure such as making a call twice in succession, both functions are compatible. Easy-to-use remote control can be performed.

Further, by adding a condition that the interval of the arrival time corresponding to these coincident calling telephone numbers is within a predetermined value, a simple procedure of making a call twice within the determined time interval can be performed. It is possible to establish a telephone line with a telephone or a remote control device that does not normally receive a call at a registered telephone terminal, and to use both functions easily,
Reliable remote control can be performed.

According to a fifth aspect of the present invention, the calling telephone number is received after detecting an activation signal indicating a calling telephone number notification sent from the subscriber line exchange, and the received calling telephone number is registered in advance. If the transmission of the calling signal is stopped before responding to the calling signal transmitted to the calling telephone number after matching the number, the telephone terminal of the received calling telephone number is called back and remote controlled. For transmitting and receiving control signals for the household equipment.

Thus, a simple operation of making a call from the registered telephone terminal to the home and disconnecting during the call can be performed.
Callback is automatically made from the remote control device, and remote control can be performed reliably. In addition, a situation in which a call for the purpose of a call is received by the remote control device does not occur, and it is easy to use.

According to a sixth aspect of the present invention, it is possible to establish one of a telephone line for remote control and a telephone line for controlling telephone equipment for controlling household equipment, and the subscriber line exchange transmits a call signal. First, a communication line is established between the control device installed between the telephone terminal in the home and the service line and the telephone terminal outside the home by using a communication network that sends an activation signal indicating the calling telephone number notification. A remote control method for controlling house equipment, comprising: detecting a start signal indicating a calling telephone number notification sent from the subscriber line exchange; receiving the calling telephone number; and registering the received calling telephone number in advance. A telephone line for remote control is established in response to the calling signal when the telephone number matches the telephone number, and a control signal for the household equipment is configured to be able to be transmitted and received, and the control device is used for remote control. Telephone line When a predetermined command is received in an established state, a pseudo start signal and a pseudo call signal are transmitted to the telephone by the same procedure as that performed by the local exchange to notify the incoming call while maintaining the communication line. When the telephone goes off-hook in response to a call signal, the telephone is connected to a telephone telephone line, which is an original telephone line, and the telephone establishes a telephone line.

As a result, even when the communication line is established with the remote control device, the telephone can be switched to the telephone by a simple operation and the communication can be performed, and the operability is improved. In addition, a new use method is possible in which both remote control and a call are performed by a single call.
