Image sends server 2 and then sends image transmission information (S2-10) to image monitoring terminal A (1-1), and then stores server 4 transmission images to image and store request (S2-13).Image monitoring terminal A (1-1) is show image (S2-16) on monitoring image, and image is stored server 4 beginning images and stored processing (S2-19).
Here, establishing image monitoring terminal A (1-1) utilizes the last blank picture on the monitoring image to begin image display.In this situation shown in Figure 14 A and Figure 14 B.Figure 14 A is an example that can show the monitoring image of four images, is displayed on the outside output device 17 of image monitoring terminal A (1-1).In the example of Figure 14 A, monitoring image is by four windows (G01～G04) consist of., further receive in the situation of image 4 just show image 1,2,3 o'clock at current image monitoring terminal A (1-1), monitoring image changes to as shown in Figure 14B.
In Figure 14 B, four windows are show image all, can't further show new image again.Be at monitoring image in the situation of state of Figure 14 B, image monitoring terminal A (1-1) is judged as monitoring image congested (S2-22 among Fig. 8).
Detect the congested image monitoring terminal A (1-1) of monitoring image in order to inquire other image monitoring terminals that whether have the replacement processing that to carry out image display, send replacement end message requests (S2-25) to system management server 7.Replace the message format of end message request shown in the PF-06 of Figure 12.Replace the end message request to comprise the transmission source address of message and send destination-address, bag classification (replacing the end message request), identifier that image that the identifier of the congested image monitoring terminal of monitoring image and image transmission source occured sends server.Receive the system management server 7 that replaces the end message request and utilize the image monitoring terminal identifier that comprises in replacing the end message request, retrieval monitoring terminal group information D B 743 obtains the instead candidate's of processing image monitoring terminal identifier.Then, replace processing candidate's image monitoring terminal for all that obtain by said sequence, retrieval monitoring terminal state information DB investigates monitoring image and utilizes situation.
Monitoring image utilizes situation to represent the situation of the monitoring image of each image monitoring terminal, the number of pictures that utilization can utilize, the utilance of picture etc.For example in the example of Figure 14 A, the number of pictures that can utilize is 1, and the utilance of picture is 75%.Monitoring image utilizes situation to be updated termly or by certain specific opportunity.Utilize the renewal of situation to process in the back narration for monitoring image.The monitoring image of having obtained the image monitoring terminal that replaces processing the candidate utilizes after the situation, and the image monitoring terminal that system management server 7 selects to utilize the situation minimum is processing terminal instead.The picture of for example specifying the maximum image monitoring terminal of the number of pictures that can utilize or using accounts for the image monitoring terminal processing terminal instead of the ratio minimum of all pictures.
Exist in a plurality of situations of utilizing the identical image monitoring terminal of situation, can be from image monitoring terminal of arbitrary selection wherein.Here, establish and selected image monitoring terminal B (1-2).System management server 7 after the image monitoring terminal of having determined to replace processing upgrades and replaces process information DB 747.
The more news that replaces process information DB 747 has been shown among Figure 16.In replacing processing trust terminal identifier, specify image monitoring terminal A (1-1), in replacing the processing terminal identifier, specified image monitoring terminal B (1-2).Then, system management server 7 replaces the image monitoring terminal A (1-1) that processes to send replacement end message (S2-28) to request.
Replace the message format of end message shown in the PF-07 of Figure 12.Replace end message to comprise the transmission source address of message and send destination-address, bag classification (replacement end message), replace the identifier of the image monitoring terminal processed.Receive the image monitoring terminal A (1-1) that replaces end message and send server 2 transmission images transmission destination change requests to image, indicate to the image monitoring terminal that replaces processing and send image (S2-31).
Image sends the message format of destination change request shown in the PF-08 of Figure 12.Image sends destination change request and comprises the transmission source address of message and send destination-address, bag classification (image sends destination change request), should monitor the identifier of the image monitoring terminal that the identifier and replacing of the image monitoring terminal of processing is processed.In this example, image monitoring terminal A (1-1) is appointed as the image monitoring terminal that should monitor processing, image monitoring terminal B (1-2) is appointed as replaces the image monitoring terminal processed.The image that receives the change request of image transmission destination sends server 2 and utilizes the information updating image monitoring end message DB 247 that comprises in this message, utilizes Figure 15 A, Figure 15 B that the situation of renewal is described.
Figure 15 A is illustrated in the state that the congested image monitoring end message DB 247 before of monitoring image occurs image monitoring terminal A (1-1).At this constantly, image sends server 2 and is treated to prerequisite with the image monitoring of image monitoring terminal A (1-1), so the notice destination of event and image only is image monitoring terminal A (1-1), Notification Method specified event and image both.Figure 15 B is illustrated in the state of the image monitoring end message DB 247 of step S2-31 after image monitoring terminal A (1-1) receives the change request of image transmission destination.Because having notified image monitoring terminal A (1-1) to be difficult to finish the situation that image monitoring processes and the image monitoring terminal that replaces processing is the situation of image monitoring terminal B (1-2), so sending server 2, image upgrades image monitoring end message DB 247, so that image monitoring terminal A (1-1) is only carried out the notice of event, to image monitoring terminal B (1-2) transmission event and image.
After image monitoring terminal A (1-1) had notified the image monitoring terminal that replaces processing, 7 pairs of system management servers replaced the image monitoring terminal B (1-2) that processes to send agent processes request (S2-32).The message format of agent processes request is shown in the PF-09 of Figure 12.The tabulation of the identifier of the identifier of the incident management server that the image that the agent processes request comprises the transmission source address of message and sends destination-address, bag classification (replacing processing request), image transmission source sends the identifier of server, be associated with image transmission server and all video cameras that are associated with these servers.The image that will comprise in the replacement end message request that step S2-25 receives sends the image transmission server that server is appointed as the image transmission source.By utilizing image to send the identifier retrieval video camera information DB 741 of server, can obtain the tabulation of incident management identifier server and video camera identifier.The image monitoring terminal B (1-2) that receives the agent processes request upgrades monitored object video camera information DB 141.Utilize Figure 17 A, Figure 17 B that more news is described.
Figure 17 A represents that image monitoring terminal B (1-2) receives agent processes request monitored object video camera information DB 141 before.At this constantly, monitored object video camera information DB 141 keeps image as original monitored object to send the identifier of server 2-2, incident management server 3-2, all video cameras associated with it.In monitoring the processing classification, specify usually and process.After receiving the agent processes request, monitored object video camera information DB 141 is varied to shown in Figure 17 B.Newly appended by agent processes request appointment, image sends the information of server 2-1, incident management server 3-1, video camera associated with it.The supervision of these video cameras is processed to specify in the classification and is replaced processing.
Image monitoring terminal A (1-1) is after preparation is processed and finished in the replacement of system management server 7 trust image displays, further detect at incident management server 3 in the situation of event (S2-34), incident management server 3 sends server 2 to image and sends event notices (S2-37).
Image sends server 2 with reference to the image monitoring end message DB247 under the state that is in Figure 15 B, and having grasped need to be to image monitoring terminal A (1-1) transmission event and to the situation of image monitoring terminal B (1-2) transmission event and image.Situation for the image display that should process image monitoring terminal A (1-1) notice has been disposed by the image monitoring terminal B (1-2) of terminal instead sends event handling notice (S2-40).
The message format of event handling notice is shown in the PF-13 of Figure 13.Event handling notice comprise the transmission source address of message and send the identifier of the identifier of the incident management server of destination-address, bag classification (event handling notice), notification source, institute's event, identifier, the event of the video camera that is associated with event occur constantly, image recording zero hour, image recording finish time, image are stored identifier server, carried out identifier, the precedence designation of the image monitoring terminal of replacement processing., can set as required precedence designation herein, in step S2-40, not set precedence designation.Then, image sends 2 pairs of servers and replaces the image monitoring terminal B (1-2) that processes to send respectively event notice, image transmission (S2-43,46), and then, the image request of storing is sent to image store server 4 (S2-55).Image is stored the storage storage (S2-58) of server 4 beginning images.
The image monitoring terminal A (1-1) that receives the event handling notice in step S2-40 is presented at received information on the picture.Because all windows of the monitoring image of image monitoring terminal A (1-1) are all just at show image, so information is presented among the list of thing window E01.
Figure 18 B has identified the particular content of event list window.List of thing window E01 also comprises the identifier that has carried out replacing the image monitoring terminal of processing except comprising event ID, video camera identifier, event generation constantly.
Image sends server 2 pairs of image monitoring terminals B (1-2) and sends event notice and image transmission message (S2-43,46).The image that on the monitoring image of image monitoring terminal B (1-2), shows the image of usually processing and replace processing with the form that can distinguish.Such as considering to change the color of window frame or making the methods such as edge chap.Figure 19 illustrates this situation.By above a series of processing, realized the replacement Graphics Processing of image.
Like this, by the sequential among Fig. 8, make the image monitoring terminal B (being equivalent to the second image monitoring terminal) in the image monitoring terminal 1 replace image monitoring terminal A (being equivalent to the first image monitoring terminal) to show the event that was originally monitored by image monitoring terminal A.
And presented event list window E01 on image monitoring terminal A points out to exist this terminal to process and untreated event, and whether this event has other image monitoring terminals to carry out replacing the situation of demonstration.
More than describe the situation that system management server is dispatched the image monitoring between the image monitoring terminal in detail, but, the concrete sequential of implementing is not limited to above order, as long as can realize replacing carrying out the purpose that image monitoring is processed, certainly can carry out various changes on the basis of existing sequential and message format.
For example, event notice can send server 2 and directly send to image monitoring terminal 1 by the incident management server without image.
(other variation)
In Fig. 7, Fig. 8, no matter in which kind of situation, image sends server 2 and all can send image and store request, and the request image is stored 4 pairs of images of server and stored.
But image is stored server 4 and just is used for image is stored in order to calling in the future.Can image be set according to the characteristics that monitor the strong point and the consideration of cost etc. yet and store server 4.Particularly carried out in the situation of replacement image processing of the present invention, owing to can monitor simultaneously by scheduling more event, so the probability of happening that can't in time monitor descends, therefore, even not being set, image storage server 4 is not difficult to occur owing to congested the existence can't in time show the image that needs storage yet.Store in the situation of server 4 in that image is not set, can omit step S2-55, S2-58 etc. and image and store the relevant order of server 4.
In addition, in Fig. 8, receive the system management server 7 that replaces the end message request and utilize the image monitoring terminal identifier that comprises in replacing the end message request, retrieval monitoring terminal group information D B 743 obtains the instead candidate's of processing image monitoring terminal identifier.
That is to say that in the first embodiment, system management server 7 only selects to replace the image monitoring terminal identifier processed in being in the scope of the image monitoring terminal in a small group with image monitoring terminal A.Can improve the probability that effectively monitors like this.
But, if all the image monitoring terminals in system are under the jurisdiction of under the situation that same tissue (such as bank etc.) etc. do not need to divide into groups especially, also can omit monitoring terminal group information D B 743, thereby system management server 7 directly determines to replace the image monitoring terminal processed in monitoring terminal information.
In addition, in the sequential chart of Fig. 8, utilize the list of thing window E01 shown in Figure 18 B to point out the image monitoring terminal that replaces processing, still, also can adopt other prompting modes except list of thing.Replace the label processed etc. such as directly representing to exist in image monitoring window roll display.Perhaps point out by voice and exist because the congested event of having carried out replacing processing.
(the second execution mode)
In the second execution mode, thereby utilize all image monitoring terminals also without the processing in the situation of the replacement Graphics Processing of finishing image even utilize the sequential chart explanation of Fig. 9 that a lot of events have occured.
In the second execution mode, the network configuration of image monitoring system is all identical with the first execution mode with the basic comprising of each device, therefore, quote identical label and omit detailed explanation, and on the basis of the first execution mode, stress the difference between the second execution mode and the first execution mode.
Fig. 9 is the precedence diagram that the replacement of the image display when a plurality of event occurs that relates to of explanation the second execution mode is processed.Suppose in image monitoring system owing to occured that thereby all image monitoring terminals all are in congested situation in the event system that too much needs monitor, and the situation of wrong replacement end message therefore occurred.
In Fig. 9, (S3-01～S3-32) the step S2-01 with Fig. 8 carries out same processing to S2-32 in the processing that the replacement that system management server 7 entrusts image monitoring terminal B (1-2) to carry out image until the congested of monitoring image occured image monitoring terminal A (1-1) is processed.Therefore, omit the detailed description of these steps.
In addition, begin replace to process to rise from image monitoring terminal B (1-2), to receiving initial event and image and in information that show image monitoring terminal A (1-1) on the monitoring image and image monitoring terminal B (1-2) are associated and (S3-34～S3-58) the step S2-34 with Fig. 8 also is identical to S2-58 by the processing till the image storage server 4 storage images.Therefore, omit the detailed description of these steps.
As shown in Figure 9, shown that at step S3-52 the image monitoring terminal B (1-2) of image detects the congested of monitoring image, thereby be varied to Figure 14 B (S3-64).Image monitoring terminal B (1-2) sends to system management server 7 and replaces the end message request, entrusts the replacement of image display to process (S3-67).
Here, establish system management server 7 retrieval monitoring terminal group information D B 743 and monitoring terminal state information DB 745, the monitoring image that detects all terminals in the monitoring terminal group all is congestion state.System management server 7 sends to image monitoring terminal B (1-2) and replaces end message (S3-70), is set as null value in the hurdle of the replacement monitoring terminal identifier of the replacement end message (PF-07) of this moment.Receiving the image monitoring terminal B (1-2) that replaces end message is in the situation of null value according to replacement monitoring terminal identifier, detects not exist to replace processing monitoring terminal, stops request and send the image transmission to image transmission server 2.
The message format that the image transmission stops to ask is shown in the PF-10 of Figure 13.Image sends and stops to ask to comprise the transmission source address of message and the identifier of the image monitoring terminal that transmission destination-address, bag classification (image sends and stops request), the transmission of request image stop.Receiving image sends the image stop to ask and sends server 2 and upgrade as shown in figure 20 image monitoring end message DB 247.
Since do not exist can show image the image monitoring terminal, so the Notification Method of event all is set to " only event ".In this state, establish incident management server 3 and further detect event (S3-76), and image transmission server 2 has been sent event notice (S3-79).
Image sends server 2 retrieval image monitoring end message DB 247, detect do not exist can show image the image monitoring terminal, process (S3-82,85) and the image monitoring terminal A (1-1) of the object that becomes event notice and image monitoring terminal B (1-2) are sent event notice.
Here, do not replace the terminal processed owing to do not exist, so in event notice is processed the hurdle of replacement processing terminal identifier of (PF-13), be set as null value.In addition, in the hurdle of the image monitoring terminal identifier of event information DB 243, be set with null value, in the hurdle of the event notice destination of event information DB 243 terminal identifier, be set with image monitoring terminal A (1-1) and image monitoring terminal B (1-2).Receive image monitoring terminal A (1-1) and image monitoring terminal B (1-2) presented event list window (S3-94,97) on monitoring image that event notice is processed.Show this situation at Figure 21.
Shown in Figure 21, owing to be set as null value in the hurdle of the replacement processing terminal identifier of list of thing, this event is not also processed by any image monitoring terminal thus.Corresponding image is sent server 2 and is sent to image storage server 4 from image, carry out to store and process (S3-88,91).If carried out after above the processing, through certain hour, the demonstration of certain image finishes the picture relieve congestion in image monitoring terminal B (1-2).At this moment, image monitoring terminal B (1-2) selects the not event (S3-100) of demonstration from list of thing, carries out the picture disply of image.The system of selection of event can consider to have the method that for example shows generation moment event the earliest, perhaps by the observer event setup priority is carried out as shown in figure 22 the method for processed.Image monitoring terminal B (1-2) after the event of having determined show obtains request with image and sends to image storage server 4 (S3-103).
Image is obtained the message format of request shown in the PF-11 of Figure 13.Image obtain request comprise the transmission source address of message and send the identifier, event ID of the image monitoring terminal of destination-address, bag classification (image is obtained request), request image, the moment occurs in identifier, the event of the video camera that is associated with event.Receive image obtain the image of request store server 4 from image information DB441, obtain with message in event ID, video camera identifier, event constantly corresponding image occurs, send to image monitoring terminal B (1-2) (S3-106).
Then, send server 2 transmission images to image and obtain information, notify to have from the image of image monitoring terminal B (1-2) and obtain request (S3-109).
Image is obtained the message format of information shown in the PF-12 of Figure 13.Image is obtained identifier, event that information comprises the transmission source address of message and send the identifier, event ID of the image monitoring terminal of destination-address, bag classification (image is obtained information), request image, the video camera that is associated with event the moment, image recording zero hour, image recording finish time is occured.Receive that image obtains that the image of information sends that server 2 utilizes that event ID, video camera identifier, event in the message occurs constantly, image recording zero hour, image recording finish time, retrieval event information D B 243 obtains the information of corresponding event.In the event information of obtaining by said sequence, the image monitoring terminal identifier is that the tabulation of sky and event notice destination terminal identifier comprises image and obtains in the situation of monitoring terminal identifier of information, image transmission server 2 is obtained the monitoring terminal identifier that comprises in the information with image and is set as the image monitoring terminal identifier, image monitoring terminal in the tabulation of event notice destination terminal identifier, except image is obtained the monitoring terminal identifier that comprises in the information sends event handling notice (S3-112).
Utilize Figure 23 A and Figure 23 B that this situation is described.Figure 23 A is the state of the event information DB 243 when image transmission server 2 receives event notice in step S3-79.At this constantly, this event is notified to image monitoring terminal A (1-1) and image monitoring terminal B (1-2), but image is not sent to any image monitoring terminal, so the image monitoring terminal identifier is set to sky.
Figure 23 B is the state of the event information DB 243 when image sends server 2 and receives image and obtain information in step S3-109.
Because the image corresponding with this event shown by image monitoring terminal B (1-2) at step S3-106, so the image monitoring terminal identifier is set to image monitoring terminal B (1-2).When step S3-112 has determined the transmission destination of event handling notice, the terminal that is judged as corresponding to receiving event but does not receive image is image monitoring terminal A (1-1), and sends the event handling notice to image monitoring terminal A (1-1).
At this moment, setting of image monitoring terminal B (1-2) in the hurdle of the replacement processing terminal identifier of event handling notice (PF-13).The image monitoring terminal A (1-1) that receives the event handling notice obtains the information of corresponding event from list of thing, setting of image monitoring terminal B (1-2) in replacing the processing terminal identifier illustrates the replacement of having carried out image display and processes (S3-115).The state of the list of thing of this moment is identical with Figure 18 B.By above processing, even under the state that in all image monitoring terminals, all temporarily can't replace processing, also can continue the replacement of image display and process.
(variation)
More than, in the situation that does not have the image monitoring terminal that to carry out image replacement supervision processing, the image of the event of being untreated is kept in the image storage facility, and in relevant this preservation situation of image monitoring terminal prompting, when the image of the image that the event of being untreated occurred showing replaced monitoring terminal, the sequencing that above-mentioned image storage facility is preserved according to event sent corresponding image to the image monitoring terminal.
But the image storage facility also can send untreated image to the image monitoring terminal according to other orders.For example in the terminal that obtains request according to the transmission image, should preferentially send to corresponding image monitoring terminal by the image that the requesting terminal monitors with former.Perhaps the time sequencing with the event generation sends image on the contrary, so that the more late image of time of origin is more early monitored.
(the 3rd execution mode)
In the 3rd execution mode, the sequential chart that utilizes Figure 10 is spoken frankly the congested elimination of bright monitoring image and processing in the situation that stops to replace processing.
In the 3rd execution mode, the network configuration of image monitoring system is all identical with the first execution mode with the basic comprising of each device, therefore, quote identical label and omit detailed explanation, and on the basis of the first execution mode, stress the difference between the 3rd execution mode and the first execution mode.
Figure 10 is the precedence diagram that the processing stop is processed in the replacement that makes image display that explanation the 3rd execution mode relates to.As prerequisite be, the monitoring image of image monitoring terminal A (1-1) is congested (S4-01), image monitoring terminal B (1-2) is in the process of image monitoring terminal A (1-1) carry out to replace being processed (S4-04).
Here, establish and produced the window that image display finishes in the monitoring image of image monitoring terminal A (1-1), all events in the list of thing (E01 among Figure 18 B) have been finished and have been replaced processing the congested elimination (S4-07) of monitoring image.
At this moment, image monitoring terminal A (1-1) sends server 2 to image and sends image notice request (S4-10), and the image that request begins to have stopped again sending.
The message format of image notice request is shown in the PF-16 of Figure 13.The image notice request comprises the transmission source address of message and sends the identifier of the image monitoring terminal of destination-address, bag classification (image notice request), request image notice.The image that receives the image notice request sends server 2 retrieval image monitoring end message DB 247, obtain corresponding image monitoring terminal, the Notification Method of event is set as " event and image ", and the information that deletion is relevant with the image monitoring terminal beyond this image monitoring terminal, the information of deleting specifically image monitoring terminal B (1-2).Thus, after image sends server 2 and becomes only to image monitoring terminal A (1-1) transmission event and image.And then image monitoring terminal A (1-1) is to system management server 7 transmitting apparatus state informations.
The message format of status information of equipment is shown in the PF-15 of Figure 13.Status information of equipment comprises that the transmission source address of message and identifier and the monitoring image of the image monitoring terminal that transmission destination-address, bag classification (status information of equipment), request image are notified utilize situation.Monitoring image utilizes the up-to-date information of situation reaction.The congested elimination of monitoring image in step S4-07 necessarily is set with the value that can carry out image display so utilize at monitoring image in the situation.For example, the number of pictures that can utilize is more than one, and the picture utilance becomes the value of less than 100%.
The system management server 7 that receives status information of equipment from image monitoring terminal A (1-1) utilizes the monitoring terminal identifier the message, retrieval replaces process information DB 747, judges whether to exist this terminal is carried out other image monitoring terminals that replace processing.According to above-described precondition, the state of replacement process information DB 747 becomes shown in Figure 16, and image monitoring terminal B (1-2) is carrying out and replacing processing as can be known.Therefore, 7 pairs of image monitoring terminals of system management server B (1-2) transmission agent processes stops request (S4-16).
The message format that agent processes stops to ask is shown in the PF-17 of Figure 13.The tabulation of the identifier of the incident management server that the image that agent processes stops to ask to comprise the transmission source address of message and sends destination-address, bag classification (replace processing stop request), image transmission source sends the identifier of server, be associated with image transmission server, all video camera identifiers that are associated with these servers.Image send identifier server, incident management identifier server, video camera identifier list such as with step S2-32 etc. in the replacement that receives to process the content that comprises in the request identical.Receive and replace processing image monitoring terminal B (1-2) the retrieval monitored object video camera information DB 141 that stops to ask, all video camera tabulations that deletion is corresponding.
(variation)
Except when the congested elimination of monitoring image from image monitoring terminal transmitting apparatus state information, can also be by the system management server 7 regular request state information of updating the equipment.Utilize the sequential chart of Figure 11 that this situation is described.
(the transmitting apparatus state information request of 1-1～1-N), (S5-01,04) processed in the renewal of beginning status information of equipment from system management server 7 to each image monitoring terminal.The message format of status information of equipment request is shown in the PF-14 of Figure 13.
The status information of equipment request comprises the transmission source address of message and sends destination-address, bag classification (status information of equipment request).Receive each image monitoring terminal (1-1～1-N) to system management server 7 transmitting apparatus state informations (S5-07,10) of status information of equipment request.The system management server 7 that receives status information of equipment utilizes received information updating monitoring terminal state information DB 745.
When picture disply was congested when a plurality of events occur, because the replacement Graphics Processing of image, the list of thing of each image monitoring terminal produced difference in showing.
The image monitoring terminal 1,2,3 that Figure 29 expresses 3 image monitoring terminals is carried out the replacement Graphics Processing of image mutually, and in the display frame of any terminal, there is not empty picture, in list of thing, maintains the state of event that should following demonstration.Beginning to replace Graphics Processing soon, as shown in figure 29, identical content shown in the list of thing of 3 image monitoring terminals.At this moment, when the beginning image display of list of thing was on picture, list of thing was varied to as shown in figure 30 in image monitoring terminal 2.Deletion is as " 1: person detecting " of beginning event from the list of thing of carrying out the image monitoring terminal 2 that image display processes.On the other hand, in image monitoring terminal 1,3 list of thing, in the hurdle of the replacement processing terminal identifier of this event, set " image monitoring terminal 2 ".Here, and then when image monitoring terminal 3 was carried out the Graphics Processing of the image corresponding with " 2: the retentate detection ", list of thing was varied to as shown in figure 31.In image monitoring terminal 3, deletion detects corresponding event with retentate from tabulation, in image monitoring terminal 1,2, demonstrates this event and has carried out the situation that replaces Graphics Processing by image monitoring terminal 3.And at the appointed time, deletion has implemented to replace the event of demonstration from list of thing.
State after Figure 32 has represented original adoption and replaces the demonstration of " 1: person detecting " of Graphics Processing deleted.Like this, along with the process of time, the demonstration of list of thing becomes different contents according to each image monitoring terminal.
Here, because shown list of thing not only comprises the strong point event of this terminal practical surveillance on certain image monitoring terminal, also comprise and replace the event that shows by this terminal, so, there is not shared events tabulation between the image monitoring terminal in the situation that can replace the terminal processed, can realize thus the dispersion of load, improve the efficient that monitors processing.
(the 4th execution mode)
In event, also exist to have the event of relevance, so sometimes wish to have the event of relevance and do not replace Graphics Processing by the continuous monitoring of an image monitoring terminal is a plurality of.For example, in bank, monitor near the video camera the ATM angle and monitor between the video camera of this ATM inside to have very high relevance.Event is also wished not carry out replacing processing and monitored by same image monitoring terminal when the image monitoring terminal congestion even be associated with these video cameras.
In the 4th execution mode, the processing in the situation that is set with the relevance event in image monitoring system is described.
In the 4th execution mode, the network configuration of image monitoring system is all identical with the first execution mode with the basic comprising of each device, therefore, quote identical label and omit detailed explanation, and on the basis of the first execution mode, stress the difference between the 4th execution mode and the first execution mode.
In order to realize this function, the external memory 24 of the image transmission server 2 shown in Fig. 3 also keeps the event correlation information D B 249 of the relevance between presentation of events.
The relevance of the relevance that event correlation information D B 249 comprises by event ID, have group that the identifier of the event of relevance consists of with the determined event of this event ID, be used for decision event is judged the time.Also can a relative event ID and have a plurality of correlating event identifiers.Event correlation is used to judge whether to replace the situation processed in the replacement Graphics Processing of image, occured within the relevance judgement time in the situation of the correlating event corresponding with event ID, is considered as having relevance between two events.
Owing to have event correlation information D B 249, when the event that detects belongs to correlating event, even the image monitoring terminal is under the congested state, also do not carry out the replacement Graphics Processing of other image monitoring terminals.
Utilize the sequential chart of Figure 33 that this processing is described.The processing of the step S3-01 of the processing of step S4-01～S4-31 and Fig. 9～S3-31 is identical in Figure 33.That is, in image monitoring terminal A (1-1), owing to receiving image the congested of monitoring image occurs, image monitoring terminal A (1-1) sends server 2 notices to image and replaces processing terminal.Under this state, further produce new event (S4-34), incident management server 3 sends server 2 to image and notifies this situation (S4-37).
Here, image sends the event ID that server 2 uses the event of notifying, and retrieval event related information DB 249 obtains identifier and the stand-by time of the event that is associated with the event of notifying.
Then, utilize the identifier of obtained these correlating events, retrieval event information D B 243 judges receiving event notice from step S4-37 begins whether to exist the correlating event that has occured in the relevance judgement time.In the situation that past in correlating event is the relevance judgement time occurs, will there be relevance between the event that the event that receive among the step S4-37 is considered as and the past occured, to the image monitoring terminal notification event identical with the past event.
Here, be located at step the S4-04 event of notifying and the event of notifying at step S4-37 and have relevance.In step S4-31, send in the server 2 at image, set as the transmission destination of image and to have replaced the image monitoring terminal B that processes, but with reference to event information DB 243, detected the image corresponding with the event of step S4-04 and be sent to image monitoring terminal A.In addition, distinguish that image monitoring terminal A has occured congested and can't show image.Therefore, image sends server 2 and sends event handling notice (S4-40) to image monitoring terminal A, substantially the image monitoring terminal B that is processing is not sent whatever.
When sending the event handling notice.Image sends server 2 and precedence designation is set as " effectively ", sends.Receive the beginning that image monitoring terminal A that precedence designation is set to the event handling notice of " effectively " will received event be appended to list of thing, so that event can be by the earliest processing (S4-43).
