This is performed by interposing the analog line terminal 13. However, those operations are the same as the operations of a normal terminal adapter for ISDN, and therefore will be omitted here.

In the following description, the emergency call device 10 uses the police station, that is, the special number "1" as the call destination.
It is assumed that “10th” is set. Then, as described above, the control unit 120 of the emergency notification video transmission device 100.
It is assumed that the notification destination and the telephone number assigned to the line interface device 5 of the video reception device 4 which is the video information transmission destination are stored in association with each other.

In the emergency notification video transmission device 100, the
Captures still images from video signals from one or more cameras at set intervals and
It is compressed by the PEG method and stored in the video storage memory 121 (step S201).

Then, the emergency notification video transmission device 100 is
The emergency notification device 10 is activated in response to the activation signal, and it is determined whether or not a line capture request has been sent from this emergency notification device 10 (step S202). This determination is made by the control unit 12 through the analog line interface unit 113.
0 does. When the line capture request is not detected, the process returns to step S201, and the operation of accumulating still image information based on the image signal from the camera is continued.

Further, in step S202, the control unit 120
When detects a line acquisition request from the emergency notification device 10, the control unit 120 determines whether the ISDN line 1 is in use (step S203). If the ISDN line 1 is in use, the control unit 120 forcibly disconnects the ISDN line in use, forcibly opens it, and sends 2 for emergency call.
Form an empty B channel (step S20).
4).

At this time, in this example, not only when both the two B channels of the ISDN line 1 are in use, but even when only one of the two B channels is in use, the compulsion is forced. The ISDN line 1 is opened and opened.

In step S203, 2 of ISDN line 1 is selected.
When it is determined that two B channels are free,
When the ISDN line 1 that was being used is forcibly released in step S204, the control unit 120 captures the vacant ISDN line 1 and outputs a dial tone from the analog line interface unit 113 to indicate this. It controls to send to the reporting device 10 (step S
205). Then, the control unit 120 stops capturing the accumulated video (step S206).

As is clear from the above description of the operation of the emergency notification device 10, when the emergency notification device 10 confirms that the line is captured, the emergency notification device 10 dials the stored telephone number of the notification destination. In the case of this example, "110" is dialed out.

The emergency notification video transmission device 100 monitors the dial number from the emergency notification device 10 (step S2).
07), in this example, it is determined whether it is a special number (step S).
208). The process of step S208 is for determining whether or not there is a video information transmission destination related to the notification destination.
In the case of this example, it is assumed that the video information transmission destination always exists in the special number “110”.
By determining whether or not the special number is “110”, it is possible to determine whether or not there is a video information transmission destination related to the notification destination.

In the case of a report destination other than the special number, by checking whether the telephone number of the video information transmission destination corresponding to the report destination telephone number is stored in the built-in memory of the control unit 120, The process of step S208 can be performed.

When it is determined in step S208 that it is not a special number, that is, in the case of this example, the emergency notification device 1
When it is determined that there is no related video information transmission destination, the notification destination from 0 sends an ISDN-like notification using only a voice notification message from the emergency notification device 10.
Processing for performing the processing through line 1 is performed (step S209).

When it is determined in step S208 that it is a special number, that is, in the case of this example, the emergency notification device 1
When it is determined that there is a related video information transmission destination in the notification destination from 0, in addition to the voice notification message from the emergency notification device 10, the video information captured by the camera is displayed.
A process for transmitting through the ISDN line 1 is executed (step S210).

When the notification processing operation of step S209 or step S210 ends, step S20
Return to 1 to restart the accumulation of video from the camera and wait for the next notification request.

Next, the processing for transmitting the voice message and the visual notice in step S210 through the ISDN line 1 will be described with reference to the flowchart of FIG.

First, the dial number information sent from the emergency notification device 10 is the analog line interface unit 1
It is supplied to the control unit 120 through 13. Control unit 120
Stores the dial number information in the built-in memory and performs a call operation to the ISDN line 1 based on the dial number information. That is, a "SET UP" message is sent to the ISDN line 1 (step S30).
1).

Then, in order to notify the emergency call device 10 that the other party is calling, the analog line interface section 11
3 is controlled to send a ring back tone (RBT) to the emergency notification device 10 (step S302). Then, it waits for a response from the report destination (report destination telephone device 3) to this call (step S303).

When the response of the report destination is detected, the control unit 120 parallelizes the process for the voice report from the emergency report device 10 and the process for transmitting the video information based on the video signal from the camera. To execute.

First, a process for making a voice notification from the emergency notification device 10 will be described. That is, when the control unit 120 detects the response of the call destination, it controls the analog line interface unit 113 to make the emergency call device 10
The ringback tone that has been sent to is stopped (step S304).

Since the emergency call device 10 detects the response of the callee due to the stop of the ringback tone, it sends a report message. This notification message is sent to the ISDN interface unit 112 through the analog line interface unit 113 of the emergency notification video transmission device 100, encoded, and sent to the ISDN line 1 (step S305).

When the sending of the notification message is completed, the emergency notification device 10 enters the state of waiting for the reverse communication from the special number and temporarily opens the line. The control unit 120 of the emergency notification video transmission device 100 waits for the detection output of the line open by the emergency notification device 10 through the analog line interface unit 113 (step S306). Control unit 12
0 is the detection output of this line release and the notification detection circuit 11
The reverse communication standby state of the emergency notification device 10 is recognized from the notification output signal from 5. Then, when the control unit 120 detects that the emergency notification device 10 opens the line, the control unit 120 temporarily disconnects the ISDN line (step S307).

As described above, when the emergency communication device 10 does not detect the reverse communication and remains in the reverse communication standby state for 5 seconds or more, the emergency communication device 10 again captures the line. It is determined whether or not the line has been captured again (step S308).

When it is determined that the line has been captured again, the control unit 120 makes a call through the ISDN line 1 with the dial number of the report destination stored in the built-in memory (step S309). Then, the notification message subsequently sent from the emergency notification device 10 is sent to the ISDN line 1 as described above (step S310). After waiting for the line to be opened by the emergency notification device 10 (step S401), I
The SDN line 1 is disconnected (step S402), and the counterwaiting for the notification is waited for.

When the line acquisition from the emergency notification device 10 is not detected in step S308, and
Next, it is determined whether or not there has been an incoming call due to the reverse communication from the callee (step S403). If it is determined that there is no incoming call due to reverse communication, the process returns to step S308.

The control unit 120 then proceeds to step S40.
When an incoming call due to reverse communication from the callee is detected at 3, the emergency notification device 1 is notified by the detection output of the notification detection circuit unit 115.
When it is confirmed that 0 is being reported, the analog line interface unit 113 is controlled to send a call signal to the emergency notification device 10 (step S404).

As a result, only the bell of the emergency analog telephone 14 connected to the emergency notification device 10 rings, and the other analog port 104 of the emergency notification video transmission device 100 rings.
The bell of the analog line telephone terminal 13 connected to does not ring.

At the same time, the control section 120 uses the calling party number included in the "SET UP" message of the reverse communication to
The other party who called you is "110" or "11"
9 "is detected, the line connection message by the response is transmitted without waiting for the response by the off-hook of the emergency analog telephone 14 (step S40).
5) Respond to the reverse call from the callee. Then, the control unit 120 controls the analog line interface unit 113 to generate a pseudo ringback tone and send the pseudo ringback tone to the destination of the reverse communication (step S406).

After that, when the off-hook response is made by the analog telephone 14 for emergency use, the control section 120 detects the line capture by this response through the analog line interface section 113 (step S407). When detecting the response of the emergency notification device 10, the control unit 120 controls the analog line interface unit 113 to stop the generation of the pseudo ringback tone.

Thus, the emergency analog telephone 14
And the callee are in a state of mutual call through the ISDN line 1 (step S409).

After that, when the emergency analog telephone 14 makes an on-hook of the telephone as a call ending operation (step S410), the line is disconnected. With the above, the notification operation by the voice message is completed.

Next, the video transmission performed in parallel with the voice notification will be described with reference to the flowcharts of FIGS. 7 and 8.

That is, step S303 in FIG.
Then, when you confirm the response of the report destination (report destination telephone device 3),
The control unit 120 of the emergency notification video transmission device 100 reads out the telephone number of the video information transmission destination associated with the notification destination stored in the built-in memory, and reads the ISDN line 1
Using the B channel that remains as a vacant area, a call is made to the video information destination (step S50).
1). Then, it waits for a response from the video information transmission destination (step S502).

When the response from the video information transmission destination is confirmed in step S502, the video signal processing unit 116 is preset by the control instruction from the control unit 120 as a camera for transmitting the video information in this example. A video signal (a video signal captured at that time) from one of the cameras is taken in, still image information is extracted, JPEG-compressed, and sent to the control unit 120 as a real-time video. The control unit 120 sends this real-time video to the video receiving device 4 which is the video transmission destination through the ISDN line 1.

In the video receiving device 4, the video receiving personal computer 6 receives this real-time video via the line interface device 5 and displays it on its display screen.

At this time, the video receiving personal computer 6 displays on its screen a control instruction user interface for the camera switching function, the real-time video / stored video switching function, and the video size switching function of the emergency notification video transmission device 100. Thus, the user of the personal computer 6 is configured to be able to input the above-mentioned control instruction through its user interface.

Therefore, in the emergency notification video transmission device 100, the control unit 120 monitors whether or not the control instruction from the video information transmission destination is received (step S50).
4) When it is detected that the control instruction is received, it is determined what the received control instruction is (step S601 in FIG. 8).

Then, the control instruction is "switch to stored image".
If so, the video information sent to the video information destination is switched to the video information of the still image stored in the video storage memory 121 (step S602).

When the control instruction is "switch to real-time video", the video information sent to the video information destination is switched to real-time video (step S60).
3).

When the control instruction is "change video size", the video size of the video information sent to the video information destination is switched to the specified video size (step S604). As described above, in this embodiment,
There are 1/4 size and 1/1 size as the image size, and it is switched to either of them.

When the control instruction is "switch camera", the camera for acquiring the video information to be sent to the video information destination is switched to the designated camera (step S6).
05).

The above steps S602 to S60
After 5, the process returns to step S504 of FIG.
0 determines whether or not a control instruction from the video information transmission destination is received again.

When it is determined in step S504 that the control instruction from the video information transmission destination has not been received, the control unit 120 determines whether or not a line disconnection command has been received from the video information transmission destination (step S505). If the line disconnection command is not received, step S504
Return to.

When it is determined in step S505 that the line disconnection command has been received, the control unit 120
It is determined whether all the stored images in the image storage memory 121 have been sent (step S506). If the stored video in the video storage memory 121 has not been sent, the stored video stored in the video storage memory 121 is sent to the end (step S507). Then, the process returns to step S506.

When it is determined in step S506 that all the stored images have been sent, the line is disconnected (step S508). Then, the stored image in the image storage memory 121 is discarded (step S509). After that, FIG.
Returning to step S201, the storage of the video information in the video storage memory 121 is restarted.

FIG. 9 is a diagram showing an example of a notification operation sequence using the ISDN line via the above-mentioned emergency notification video transmission device 100 when an emergency notification request is issued from the emergency notification device 10.

That is, as described above, for example, when the activation of the notification based on the emergency button occurs, the emergency notification device 1
0 outputs the during-report output signal from the terminal 10b and performs the line capturing operation. Emergency report video transmission device 10
At 0, the notification output signal input through the terminal 105 is detected by the notification detection circuit 115, and the detected output is sent to the control unit 120. As a result, the emergency notification video transmission device 1
The control unit 120 of 00 recognizes that the emergency notification device 10 is in a notification operation.

Further, in the emergency notification video transmission device 100,
The analog line interface unit 113 detects the line capturing operation of the emergency notification device 10 and outputs the detected output.
Send to 20. The control unit 120 controls the analog line interface unit 113 according to the line capture detection output to supply the dial tone signal to the emergency notification device 10 through the analog port 103.

After detecting this dial tone signal, the emergency notification device 10 sends a dial number to the call destination.
In the example of FIG. 9, the number "110" is dialed out. In the emergency notification video transmission device 100, the analog line interface unit 113 identifies this dial number information,
It is sent to the control unit 120. The control unit 120 stores this dial number information in the memory and performs a call operation to the ISDN line 1 based on this dial number information.
That is, the “SET UP” message is sent to the ISDN line 1.

Then, the control unit 120 of the emergency notification video transmission device 100 has the analog line interface unit 113.
To generate a ringback tone, which is sent to the emergency notification device 10.

When the call destination responds, the ISDN exchange side sends a line connection message in response, so the control unit 120 of the emergency alert video transmission device 100
By detecting this, the analog line interface unit 11
3 is controlled, the ringback tone to the emergency notification device 10 is stopped, and the callee response is notified.

The emergency notification device 10 sends a notification message after detecting the response voice from the notification destination. This notification message is encoded by the emergency notification video transmission device 100, sent to the ISDN line 1, and sent to the notification destination.

At the same time, the control unit 120 of the emergency message video transmission apparatus 100 detects the I
The remaining B channel of the SDN line 1 is used to make a call to the line interface device 5 of the video receiving device 4. Then, after confirming the response on the line interface device 5 side, the video transmission is started as described above.
When a line disconnection command is generated by an operation of the user of the video reception personal computer 6 of the video transmission device 4, the B channel line for video transmission is disconnected.

On the other hand, the emergency notification device 10 which has sent the notification message is in the state of waiting for the reverse communication and temporarily releases the line. In the control unit 120 of the emergency notification video transmission device 100,
This line open is detected through the analog line interface 113, a line open message is sent to the ISDN exchange side, and the line is disconnected.

Then, in the control unit 120 of the emergency notification video transmission device 100, the line open detection through the analog line interface 113 and the during-report detection circuit unit 11 are performed.
The reverse communication standby state of the emergency notification device 10 is recognized from the notification output signal during notification from 5.

Then, even though the reverse connection waiting time of 5 seconds elapses after the line is opened for the reverse communication standby,
When there is no counter-reverse from the callee (FIG. 9 is the case), the emergency call device 10 performs the line capturing operation.
Then, the emergency notification video transmission device 100 detects this line capture through the analog line interface unit 113.

When the control unit 120 detects this line capture, it reads the dial number information of the callee stored in its built-in memory, and based on this, indicates the callee as the call operation to the ISDN line 1. "SE including telephone number
T UP ”message to line 1. Then, the control unit 120 sends the notification message from the emergency notification device 10 again through the ISDN line 1, and disconnects the line based on the line release from the emergency notification device 10.

After that, when the callee performs the call operation of the reverse communication, the emergency call video transmission device 100 receives the "SET UP" message at the time of the call from the ISDN exchange side. At this time, the control unit 120 detects whether or not the calling party is the “110” of the report destination based on the calling number included in the “SET UP” message.

In this case, although the incoming call due to the reverse call may be detected by detecting the special number "110", the incoming call due to the reverse call from the notification destination to which the notification message is sent may be detected. In order to ensure the detection, in this embodiment, the control unit 120 detects the coincidence with the dial number of the report destination stored in the built-in memory,
Detects an incoming call due to back contact from the callee.

Control unit 12 of emergency notification video transmission device 100
0, when it detects an incoming call due to a back contact from this callee,
After confirming that the emergency notification device 10 is in the process of being notified by the detection output of the notification-in-progress detection circuit unit 115, a call signal is generated only through the analog port 103 and sent to the emergency notification device 10. As a result, only the bell of the emergency analog telephone 14 connected to the emergency notification device 10 rings.

After that, when the emergency analog telephone 14 makes a response by off-hook, the line capture by the response is detected by the analog line interface section 113 of the emergency notification video transmission device 100. Control unit 120
When the line capture detection output from the analog line interface unit 113 is received, the ISD sends a response message.
Send to the report destination through N line 1. As a result, the emergency analog telephone 14 and the callee are in a mutual call state through the ISDN line 1.

After that, when the analog telephone 14 for emergency uses the on-hook operation as a call-end operation, the message for disconnecting the line is exchanged with the emergency report video transmission device.
The line is disconnected with the SDN switch. With that, the reporting operation is completed.

[Modification] In the above embodiment,
Since the emergency notification video transmission device 100 is not dedicated to the emergency notification device and has a port that allows connection of other general analog line telephone terminals, the emergency notification video transmission device 100 outputs the during-report output signal. It was necessary to acquire the message from the emergency notification device to detect the motion during the notification, but with the configuration of the emergency notification video transmission device 100 dedicated to the emergency notification device, it is not necessary to monitor the output signal during the notification.

In the above description, the video information transmitted as the real-time video is the video information (still image information) generated from the video signal obtained by shooting with one camera. The video information (JPEG image compression of still image data) to be transmitted is obtained by a plurality of cameras selected from four cameras, that is, in this example, two or three or all four cameras. It can also be video information (still image information) generated from a captured video.

In this case, the emergency notification video transmission device 100
Is a video receiving device 4 which is a video information transmission destination as real-time video, which is obtained by sequentially cyclically switching compressed still image information generated from video captured by a plurality of cameras in a time-division manner. To be transmitted to.

On the other hand, on the video receiving device 4 side, the screen on the display connected to the personal computer 6 is divided into the number of cameras, and the video information from each camera is displayed independently on each of the divided screens. To do so. Therefore, images from multiple cameras are
Can be observed at the same time.

Also in the case of the stored video stored in the video storage memory 121, not only the case of transmitting the compressed data of the still image generated from the video signal from any one of the preset cameras, It is also possible to store the compressed data of the still image generated from the video signals from the single cameras and switch the stored video to be transmitted for each camera that has taken the image, according to an instruction from the video receiving device 4.

In addition, in this way, the video storage memory 121
In the case of storing the video data generated based on the video signals from a plurality of cameras, even in the case of transmitting the stored video, as in the case of transmitting the real-time video described above, one unit of Not only compressed data of still images generated from video signals from cameras, but also compressed data of still images generated from video signals from multiple cameras,
It is also possible to switch over in time division and transmit sequentially.

Further, in the above-mentioned embodiment, the emergency notification video transmission device 100 monitors the dial information from the emergency notification device and determines whether it is a notification destination which is associated with a predetermined video information transmission destination. I tried to detect it,
If all the special numbers such as “110” and “119” have video information destinations and the emergency notification device 10 is dedicated to those special numbers as the notification destination, Since the line is captured, it can be recognized to perform the video information transmission. In that case, it is not necessary to monitor the dial information from the emergency notification device 10 in the emergency notification video transmission device 100.

In the above-described embodiment, the voice notification message and the video information are transmitted by using two B channels of one ISDN line, so that one I signal is transmitted.
Although the SDN line is effectively used, when the emergency notification video transmission device 100 accommodates a plurality of telephone lines, the voice notification message and the video information are transmitted through different telephone lines. You can also do so.

In that case, the plurality of telephone lines need not necessarily be ISDN lines, but may be a plurality of analog lines. The plurality of telephone lines may of course include both analog lines and ISDN lines.

For example, when two or more analog lines are connected to the emergency call video transmission device and the above-mentioned emergency call operation is performed using two analog lines, the emergency call video transmission is performed. The device may have the following functions.

That is, when a line is caught from the emergency call device 10, the emergency call video transmission device catches one of the plurality of analog lines and uses it as an emergency message for transmission of the message from the emergency call device. Connect to the reporting device.

When all the analog lines are in use when the line is caught from the emergency call device 10, the emergency call video transmission device forcibly opens the two analog lines and opens the two free lines. A line is provided, and one line is captured for transmission of a notification message from the emergency notification device 10 and connected to the emergency notification device 10. Then, the line notification is notified to the emergency notification device 10.

Then, the emergency notification video transmission device monitors the dial information from the emergency notification device 10 to check whether the notification destination indicated by the dial information has a related video information transmission destination. I'll do it. Similar to the above, if all the special numbers such as “110” and “119” have video information destinations, and the emergency notification device 10 is dedicated to those special numbers as the notification destination, Since the line is captured from the emergency notification device 10, it is possible to recognize the video information transmission. In that case, the emergency notification video transmission device does not need to monitor the dial information from the emergency notification device 10.

The notification message from the emergency notification device 10 is sent out according to the response to the notification destination through the analog line whose line has been captured.

When the emergency call video transmission device detects a response to the call destination, it sends a call to the video information destination whose telephone number is stored in the memory by using another vacant analog line. And wait for the response from the video information destination,
Video information is transmitted through the analog line.

It is also possible to determine that the voice call message is transmitted from the emergency call device using an analog line and the video information is sent using an ISDN line. In that case, ISDN for transmission of video information
Since two B channels can be used as a line, for example, images from two cameras can be sent to the image information transmission destination at the same time.

[Other Embodiments] In the above embodiments, different telephone numbers are assigned to the call destination of the voice notification message from the emergency notification device and the video information transmission destination, and When there was a response from the callee during the emergency call operation, the call was sent to the video information destination and the video information was sent. However, by capturing the two B channels of the ISDN line in advance, By effectively using them, it is possible to omit calling to the video information transmission destination.

That is, in this case, the report destination is provided with a voice information receiving section and a video information receiving section for one telephone number. For example, the receiving unit for audio information is a telephone device, and the receiving unit for video information is
It can be configured to include a personal computer.

When a line is caught from the emergency call device, the emergency call video transmission device acquires two B channels of one ISDN line in advance, and selects one of the B channels.
Assign a channel for the alert message from the emergency alert device. The B-channel is used to make a call based on the dial transmission from the emergency notification device.

In response to the call to the call destination, when the response at the call destination is detected, the emergency call video transmission device
The same IS without making a call to the video information receiver.
The video information is sent to the video information receiving section through the remaining free B channel of the DN line.

At the report destination, for example, as the information, the B channel information sent in advance is discriminated as the audio information, and is received by the audio information receiving section, and the B information sent later.
By discriminating the channel information as video information and receiving it by the video information receiving unit, it is possible to separately receive the audio information and the video information.

[Other Modifications] In the description of the above embodiment, the video information to be transmitted is still image information, and the JPE is used.
Although G compression is used, it goes without saying that the compression method is not limited to the JPEG method.

Further, the video information to be transmitted is not limited to the still picture information, but may be moving picture information obtained by compressing a photographed video signal by the MPEG method or the like.

[0166]

As described above, according to the present invention, at the time of an emergency call, the image taken by the imaging device is also sent to the callee, so that the callee makes an emergency call. It becomes easy for the side to accurately judge the urgency of the emergency call.

Further, the emergency call video transmission apparatus according to the present invention has an advantage that the conventional emergency call apparatus for analog lines can be used as it is.

When not only the real-time video image when an emergency call is issued but also the video image before the emergency call is stored and the stored video information is sent to the video information receiver of the call destination In addition to determining the urgency of an emergency call, there is a possibility that the event that causes the emergency call can be determined, and the effect is remarkable.

[0169] In addition, ISD is used as a notification information transmission line.
By using the N line, it is possible to effectively use the two B channels to transmit the voice notification message and the video information through one ISDN line, which is convenient.
