Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a highly convenient emergency call system and monitoring system using a still image videophone device. Like automatic teller machines, etc.
The present invention relates to a control device for communicating between a user and a center when a trouble occurs, or for monitoring the surroundings of a device used remotely.

[Prior Art] Conventionally, in remote use devices such as automatic teller machines in banks, emergency calls in the event of trouble have been made through intercoms. In this case, the user would verbally inform the maintenance person at the center about the problem with the device, and the maintenance person would also give verbal instructions on how to deal with the problem.

Additionally, ITV cameras have been used to periodically monitor the surroundings of the device and to monitor the state of the device itself. Since the image signal from the ITV camera is a moving image, a broadband transmission line is required, and a coaxial cable or the like is used.

[Problem to be solved by the invention]

Communication using an intercom requires expressing the state of equipment trouble and how to deal with it in words, which has the disadvantage that it is difficult to convey the information well. Furthermore, a monitoring system using an ITV camera or the like has the drawback that it requires the installation of a new broadband transmission line, which is expensive. Still image videophones are devices that transmit audio and still images using existing telephone lines, but they are only operated on the premise that there are humans on the calling and receiving sides.
It cannot be used for automated monitoring purposes. In addition, when making an emergency call, the caller has to operate the device to power on and make a call each time, resulting in a lack of convenience.

[Means to solve problems]

In order to solve the above-mentioned drawbacks, the present invention includes a telephone, a still image videophone connected to the telephone, and if necessary a sensor.
This device is comprised of a control device that controls them, and is characterized by realizing emergency notification and monitoring using still images and audio without requiring a broadband transmission path and with simple operations.

〔Example] An embodiment of the present invention is shown in FIG.

Communication device A and communication device B are connected via a telephone line 4. In the following, communication device A is on the center side and communication device B is on the center side.
shall be located on the remote device side.

Each communication device is composed of a telephone, a still image videophone 2, and a control device 3. Furthermore, a sensor 7 is connected to the communication device B.

In the first invention, when the operator on the remote device side lifts up the handset 5b of the telephone 1b of the communication device B, the control device 3b
detects this, turns on the power of the still image video telephone 2b, performs automatic dialing, and calls the communication device A. When the operator on the center side lifts up the transmitting/receiving tilt 5a of the communication device A, the telephone line 4 is connected, and normal still image videophone communication is thereafter performed.

In the second invention, when there is an incoming call on the remote device side, if the handset 5b of the telephone 1b is not lifted within a certain period of time, the control device 3b turns on the power of the still image videophone 2b, and makes a telephone call. Connect line 4. When the operator on the center side transmits the specific number of the password from the communication device A using the telephone 1a, etc., the control device 3b detects the specific number, and if it is correct, transmits a still image signal from the still image video telephone 2b. If it is an error, disconnect the line.

In the third invention, when the sensor 7 connected to the control device 3b on the remote device side senses a specific situation, the control device 3b detects it, turns on the power of the still image video phone 2b, and automatically dials the phone. and calls communication device A. When the operator on the center side lifts up the handset 5a of the communication device A, the telephone line 4 is connected and a still image signal is transmitted from the still image videophone i2b.

As sensors, sensors that detect gas, fire, intrusion, etc. can be used to monitor the surroundings of a remote device. Also,
If the operation of the remote device itself is to be monitored, a control section within the device that detects failures, input of undecipherable information, etc. may be regarded as a sensor.

FIG. 2 shows another embodiment of the invention, in which two telephone lines 6 in addition to telephone line 4 are used.

Other components are the same as in FIG. 1. In normal still image videophone communication, voice and still images are switched and one or the other is transmitted, so voice calls cannot be made while still images are being sent or received. In this embodiment, still images and
It is very convenient because voice is transmitted and received through the telephone line 6.

FIG. 3 is a drawing showing an example of the configuration of the control device 3b on the remote device side.

When only the telephone line 4 is used via the still image video telephone 2b connected to the terminal port, when the handset 5b of the telephone 1b is lifted, the hook detection circuit 23 detects this and notifies the CPU 26. The CPU 26 operates the relays at the terminal ports to form a loop. In addition, the controller 27
and still image video phone 2b0) via terminal C.
Turn on the power automatically. The CPU 26 operates a DTMF (dial tone multifrequency) transmitter 25 to transmit the number of the other party's communication device, which is set in the memory.

The other party responds and sends a response signal using a dial signal, so the DTMF receiver 25 detects it, and the CPU 26 connects the terminal to the telephone 1b, thereby starting communication. - Only the line is used In this case, the still image signal and the audio signal are switched to communicate.Before connecting the terminal port to the telephone 1b, the CPU 26 operates the DTMF transmitter 25,
If the ID number of the own device is sent, the center side can immediately know which device is sending the report, which is even more convenient.

When there is an incoming call from the other party's communication device A, the ringer circuit 22 at the terminal port detects it and notifies the CPU 26. C.P.
The hook detection circuit 23 of U26 detects hook-off, and if there is hook-off, normal communication is performed. If there is no hook-off for a certain period of time, activate the relay and DT.
A station line loop is formed by the transformer coil on the MF transmitter 24 side. The controller 27 is operated to automatically turn on the still picture video telephone 2b via the terminal C. At the other party's communication device A on the center side, the operator dials a specific number representing a password or automatically dials a specific number stored in memory, which is sent to communication device B, so the DTMF receiver Decipher with 25 and controller 27
The still image video telephone 2b is instructed to transmit a still image via the still image video telephone 2b. When the transmission is completed, the CPU 26 disconnects the line.

If the specific number is incorrect, CP will not send the still image.
U26 disconnects the line. Note that after the transmission of a still image is completed, the device enters a standby state and receives an instruction signal from the other party's communication device using DTM.
It is also possible to decode the still image with the F receiver 25 and transmit the still image again.

In the case of a call originating from sensor 7, the signal from sensor 7 is C
When input to the PtJ 26, the CPU 26 forms a station line loop as described above. Then, via the controller 27, the still image video telephone 2b is instructed to transmit a still image. If the ID number of the own device is sent, the center side can immediately know which device is sending the report, which is even more convenient.

In the case of using two lines, the telephone line 6 is connected to the terminal A for voice communication, and the telephone line 4 is connected to the terminal port via the still image video telephone 2b for still image communication.

In the case of a call from communication device B, still image video phone 2
After automatically turning on the power of B and connecting it to the other device using the same procedure as when using one line above, switch the relay and connect the DTM.
The number of the partner device is sent from the F transmitter 24 to terminal I, and a connection is established with terminal I of the partner device. After connection, terminal A is connected to telephone 1b via a relay. Alternatively, it is of course possible to first make a call using the communication line 6 of terminal A, and then connect the communication line 4 of terminal port.

A call from the other party's communication device A can be received either through the terminal or through the mouth. The ringer circuits 21 and 22 are means for detecting when there is an incoming call from the other party's device. If there is a hook-off within a certain period of time, both terminal A and mouth are connected to the line as described above, resulting in two-line communication for audio and still images. If there is no hook-off, it is the same as the case of using one line, and there is no need for two-line communication.

FIG. 4 is a drawing showing an example of the configuration of the control device 3a on the center side. The basic configuration is the same as that in FIG. 3, but since it accommodates a plurality of remote device side communication devices, it is equipped with a display that displays the ID of the communication destination and an input device that requests retransmission.

As an example of further improving the convenience of the present invention, if the control device 3b of the communication device B is provided with an automatic answering function, when the handset 5b is lifted, the message "The center is currently calling. Please wait for a while" will be displayed. It is possible to output a message, and when a call is received on communication device B, it is possible to output guidance such as "Please enter your PIN number" to the other party.To achieve this, , a voice synthesis means controlled by the CPU 26 may be connected to the telephone line and controlled to be connected or disconnected as appropriate.These functions can be added in various ways without departing from the gist of the present invention.

In the above explanation, an example was given in which the hook-off state is achieved by lifting the handset 5b of the telephone 1b, but the hook-off state can also be achieved by button operation, etc., without lifting the handset as in recent telephones. It is clear that there is no problem in using the function if the device is capable of doing so.

〔Effect of the invention〕

As described above, the present invention provides a highly convenient emergency notification system and monitoring system that can be added to a remote device. When a problem occurs, the user simply lifts up the device's handset and the device connects to the center, allowing the user to be notified of the problem via video and audio, and to learn how to deal with the problem.

Furthermore, since images of the surroundings of the device can be automatically obtained from the center side even when an operator is not present on the remote device side, a simple monitoring system using a telephone line can be realized.

Furthermore, a sensor detects a specific situation on the remote device side, and if there is an abnormality, a call is automatically made to the center side and a video is sent, making it possible to realize an emergency notification system.

In the above explanation, the configuration added to a remote device has been taken as an example, but even if there is no remote device and only the device example of the present invention is used, it is still highly effective for use in emergency notifications, monitoring, etc.
