Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of industrial application to which the invention pertains The present invention relates to a remote control device using a telephone line, and in particular, in offices etc., it is connected to an extension line of a PBX or key telephone device. The present invention also relates to a remote control device suitable for connecting to an extension line of a home exchange or the like in the home.

(2) Conventional technology Traditionally, a remote control device was connected to an outside line (a subscriber's line via a switching center), and when it detected a ringing signal from the outside line and automatically received a call, it used a switch etc. to switch between an out-of-home mode and an at-home mode. For example, in the former case, the call will be automatically received when the call signal is received 3 times because the user is absent, and in the latter case, the call will be automatically received when the call signal is received 20 times because the user is at home and does not pick up the handset. However, when the user is at home, the call is not automatically received immediately, but instead the call is made available to the user who is at home and can answer using the telephone. In addition, after an automatic call is received, a response message is sent from a voice synthesis circuit, etc. to calls made via an external telephone line by an unspecified number of people who are not necessarily users, and a PIN code is received as a security measure. For the first time, the system starts receiving control codes for remote control.

On the other hand, in a PBX or key telephone device, the user distinguishes and identifies incoming calls from the outside via the telephone line (hereinafter referred to as incoming external calls) and incoming calls from within via the extension line (hereinafter referred to as incoming internal calls). Generally, the sending pattern of the calling signal is changed to make it possible. In such cases, if a conventional remote control device is connected to an extension of a PBX, key telephone device, etc., even if the user of the remote control device recognizes that the call is an extension call from the beginning, Depending on the number of times the call signal is received according to the out-of-home mode or at-home mode, the call is automatically received, a response message is sent, and the operation waits for the input of the password code. Therefore, in order to perform remote control from an internal key telephone, etc., it takes time for the remote control device to automatically receive a call, and operations such as inputting a password manually cannot be simplified, which is inconvenient.

(3) Object of the Invention An object of the present invention is to provide a remote control device that can simplify the operation of receiving such extension calls and at the same time shorten the time required for remote control.

(4) Structure and operation of the invention In order to achieve this object, the present invention provides that a remote control device has a calling signal detection circuit that detects a calling signal, and a microprocessor that controls the remote control device has a ring signal detection circuit that detects a calling signal. A means is provided to identify whether an incoming call is an external call or an extension call by looking at the signal from the signal detection circuit, and in the case of an extension call, for example, the number of times the ringing signal is received is set to one, and no response message is sent and the password is not sent. It is configured to immediately enter the control code reception operation without requiring the input of a code, thereby improving the operability of the remote control.

An embodiment of the remote control device of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic diagram of a remote control device according to the invention. In FIG. 1, 1 is the main body of the remote control device, a microprocessor 2 that controls the remote control device 1, and a telephone line 3.
an outside line terminal 4 for connecting the telephone line 3, etc., an incoming call detection circuit 5 for detecting a ringing signal, a relay 6 and a cotton lance 7 for closing the line loop when automatically receiving an incoming call, and a PIN code from the telephone line 3, etc. A tone decoder circuit 8 that determines the control code and a voice synthesis circuit 9 that sends out a response message, an input/output circuit 10 that sends and receives signals for remote control, a controlled device terminal 11 that connects a remotely controlled device, It is comprised of a mode switching circuit 12 and the like that switches between mode and at-home mode.

FIG. 2 is a diagram in which the remote control device 1 is connected to a button telephone system ffKTS. 13 is a button telephone main device, 14 is an external public telephone, 15 is a switching office that provides telephone lines, 1
6 is a slave unit of the button telephone device KTS and is the main button telephone device 1
This is a key phone connected to 3.

Here, an example of an operation in which a user performs remote control from the outside using the public telephone 14 and an example of an operation in which the user performs remote control from the inside using the key telephone 16 will be described below.

1) An external remote control user calls a public telephone n. Make a call from 14 and switch to 15
When the button telephone main device 13 receives the calling output from
The key telephone main device 13 sends a ringing signal A to the remote control device 1 to notify the remote control device 1 of an incoming external call, as shown in FIG. 3, for example.

In the remote control device 1, the microprocessor 2 identifies the incoming call by looking at the output signal of the incoming call detection circuit 5, and also determines that it is the ringing signal pattern A of "incoming outside line" shown in FIG. 3, and switches the mode. When the number of times the call signal is received according to the out-of-home mode/at-home mode set in the circuit 12 is counted (3 times/20 times), the relay 6 is operated to close its contact 6a, and the line transformer 7 closes the line loop. The call is automatically terminated, and a response message is output from the voice synthesis circuit 9 and sent to the public telephone 14 via the telephone line 3.

After the user hears the response message from the remote control device 1, when the user enters the PIN code, the PIN code is 1.-
is detected by the decoder circuit 8.

When the output signal of the microprocessor 2 of the remote control device 1 and the decoder circuit 8 matches the password code set in the remote control device 1, an acceptance sound is output from the voice synthesis circuit 9. It is sent to the user side via the telephone line 3. When the user enters a predetermined control code that corresponds to the control item of the desired controlled device after hearing one sound, the microprocessor 2 of the remote control device 1 is activated. The control code of the output signal of the decoder circuit 8 is identified, and the human output circuit 1 is output according to the control code.
At 0, remote control is performed to perform the corresponding control item and the controlled device is controlled. At the same time, a confirmation message notifying that remote control has been performed is output from the voice synthesis circuit 9 to the user side.

When the user hears the second confirmation message and confirms that the controlled device has been remotely controlled, the user inputs a control code to end the remote control and ends the call. On the other hand, the microprocessor 2 of the remote control device 1 looks at the output signal of the tone decoder circuit 8, and if it determines that it is a control code for ending remote control, it restores the relay 6 and opens the line.

2) Remote control from inside When the user dials the extension number assigned to the remote control device W1 from the key telephone 16, the key telephone main device 13 indicates, for example, "incoming extension call" as shown in FIG. A call signal B is sent out to notify the user. Remote control device 1
Then, the microprocessor 2 looks at the output signal of the incoming call detection circuit 5 and determines that it is an incoming call, and at the same time determines that it is the ringing signal pattern B of "incoming extension call" shown in FIG. The voice synthesis circuit 9 outputs the signal to the key telephone 16 via the telephone line 3.

After the user of the button telephone 16 hears the reception tone, the remote control operation for starting the controlled device is the same as the above-mentioned external remote control operation.

FIG. 4 shows an operation flowchart of the remote control device 1 according to an operation example of the external remote control and the internal remote control. Further, an operation flowchart showing an example of the operation of a conventional remote control device is shown in FIG.

As is clear from comparing the two, in the case of the present invention, the fourth
As shown in the figure, after the incoming call is detected in (1), it is determined whether the incoming call is an external line or an extension in (2), and when it is determined that the incoming call is an extension call, the line loop is immediately closed in (9). Then, without sending the response message in (7) or determining whether the password code matches in (8), the process moves to sending out the acceptance sound in 00). As shown in the conventional example in Figure 5, incoming call detection (1)
→ Detection of home/outing (3) → Detection of 20 ring signals (4)
→ Line loop detection (6) → Response message sending (7) →
Compared to performing remote control by receiving an extension call by following the process of detecting PIN code match (8) → sending reception sound θ0),
It can be seen that it is possible to simplify the operation and shorten the time required for remote control.

In FIGS. 4 and 5, (11) is the detection of whether or not a control code has been received, 02) is the sending of a remote control signal, (13) is the sending of a confirmation message, and 圓 is the opening of the line.

(5) Effects of the Invention As explained above, the remote control device of the present invention is connected to the extension of a Pokun telephone device, etc., and when the user remotely controls it from inside using a key telephone device, etc., the remote control device of the present invention After dialing the extension number of the button telephone device etc. assigned to the device, a few seconds later you will hear the reception tone from the remote control device and can enter the control code to remotely control the controlled device. Unlike the external remote control that was used, this method has the advantage of simplifying the operation and shortening the time required to perform remote control.
