First, the configuration of the notification system according to the first embodiment of the present invention and the overview of the notification area in which the communication terminals that are the communication targets of the notification system are located will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a notification system 1 according to this embodiment. FIG. 2 is a conceptual diagram showing how the communication terminal 40 and the information acquisition device 50, which are the communication targets of the notification system 1, are arranged in the notification area 100. As shown in FIG.

As shown in FIG. 1, the notification system 1 according to this embodiment includes a base station 10, an anomaly detection device 20, and a storage 30. FIG. As shown in FIG. 2, the notification system 1 is connected to at least one communication terminal 40 by wireless communication. Also, the notification system 1 is connected to at least one information acquisition device 50 .

The base station 10 is a wireless station that wirelessly communicates with the communication terminal 40 within the notification area 100 . Also, the base station 10 is communicably connected to at least one information acquisition device 50 . The base station 10 may communicate with the information acquisition device 50 wirelessly or by wire. For example, the base station 10 is implemented by a femtocell, a wireless LAN (Local Area Network) access point, or the like. The base station 10 is controlled by a base station controller (not shown).

The base station 10 acquires the identification information and location information of the communication terminal 40 from the communication terminal 40 . Also, the base station 10 acquires information within the notification area 100 from the information acquisition device 50 . The base station 10 transmits identification information and location information of the communication terminal 40 and information within the notification area 100 to the anomaly detection device 20 .

Also, the base station 10 acquires guidance information to be transmitted to each communication terminal 40 from the abnormality detection device 20 when the abnormality detection device 20 detects an abnormality (hereinafter referred to as a problem event) in the notification area 100 . The base station 10 transmits the guidance information acquired from the abnormality detection device 20 to each communication terminal 40 .

Guidance information is information indicating to which guidance destination the user of each communication terminal 40 should be guided in response to the problem phenomenon detected in the notification area 100 . For example, the guidance information includes information that guides the communication terminal 40 to move away from the location where the abnormality occurred (hereinafter referred to as the problem event area) based on the location information of the communication terminal 40 . In this embodiment, the guidance information includes a plurality of guidance destinations for a single problem event so that individual communication terminals 40 are distributed and guided to different guidance destinations when a certain problem event occurs. Note that the guidance information may be set such that some of the individual communication terminals 40 are guided to the same guidance destination. Also, the route to reach the destination may be included in the guidance information.

Anomaly detection device 20 acquires identification information and location information of communication terminal 40 and information within notification area 100 from base station 10 . The anomaly detection device 20 analyzes information within the notification area 100 acquired from the base station 10 and detects a problem phenomenon within the notification area 100 . For example, the anomaly detection device 20 acquires information such as image information and audio information in the notification area 100, and uses the information to detect a problem event. For example, the anomaly detection device 20 detects a suspicious person or a dangerous object detected from information acquired within the notification area 100 as a problematic event.

For example, the anomaly detection device 20 uses advanced video analysis behavior detection technology when detecting a problem event from image information within the notification area 100 . Advanced video analysis behavior detection technology is a technology that analyzes video information such as still images and videos to extract the features of the shape and movement of people, animals, and objects, and automatically analyzes features that are different from normal times. .

Behavior detection technology has the following features compared to detection technology based on general image processing. First, in the behavior detection technology, features are extracted from a target moving image (hereinafter referred to as target video), and the extracted features are learned and recorded. Secondly, behavior detection technology compares and analyzes the recorded features with the features of the current target video to identify the differences between the features of the current target video and the features of the current target video. Extract as an event.

For example, the anomaly detection device 20 analyzes not only the shapes of animals, people, and objects, but also their movements to detect differences in the target video from normal times as problem phenomena. When the problem event is detected, the abnormality detection device 20 uses the occurrence of the problem event as a trigger to perform video recording and alarm notification. For example, the anomaly detection device 20 compares the features of the normal time and the features of the target video, and numerically displays the degree of similarity and difference between the compared features.

In the method of the present embodiment, an abnormality is detected by extracting changes in features, so the amount of calculation can be reduced as compared with the general proposal method that compares the images themselves. Therefore, the software that implements the method of the present embodiment operates in real time even on an embedded CPU (Central Processing Unit). Moreover, the technique of the present embodiment can be implemented using various forms of provision such as hardware, software, and systems according to the intended use.

In this embodiment, by combining the action detection technology by the anomaly detection device 20 and the function of sending an alarm to the communication terminal 40, the individual communication terminals 40 are notified of the occurrence of the problem event. Further, in the present embodiment, each communication terminal 40 is notified of the guide destination according to the position information of each communication terminal 40 with the occurrence of a problem event as a trigger. In particular, in the present embodiment, guidance information is applied so that individual communication terminals 40 are distributed and guided to different guidance destinations as much as possible.

Upon detecting a problem event within the notification area 100 , the anomaly detection device 20 acquires guidance information corresponding to the detected problem event from the storage 30 . When detecting a problem event within the notification area 100, the anomaly detection device 20 notifies each communication terminal 40 residing within the notification area 100 that the problem event has occurred, and also provides information on the guide destination (hereinafter referred to as , guidance information) is notified to each communication terminal 40 .

The storage 30 is a storage that stores guidance information to be transmitted to the user using the communication terminal 40 . For example, the storage 30 stores a guide information table that tabulates guide information including information about notification areas, problem occurrence locations (also called problem event areas), problem events, guide destinations, routes to guide destinations, and the like. The guidance information table includes a plurality of guidance information and includes information regarding at least two guidance destinations for a single problem event.

A communication terminal 40 is a wireless terminal used by a user to use the notification system 1 . Communication terminal 40 has a function of acquiring its own location information, and transmits its own identification information and location information to notification system 1 . For example, the communication terminal 40 is implemented as a radio terminal that communicates with a base station such as a femtocell or a wireless LAN (Local Area Network) access point.

Communication terminal 40 has a function of acquiring its own location information. For example, communication terminal 40 obtains its own location information using a GPS (Global Positioning System) function. The communication terminal 40 also receives guidance information provided by the notification system 1 within the notification area 100 . Communication terminal 40 is implemented by a mobile wireless terminal such as a general smart phone, tablet, or mobile phone.

The information acquisition device 50 acquires information within the notification area 100 . For example, the information acquisition device 50 is implemented by a camera that captures moving images within the notification area 100 . Also, for example, the information acquisition device 50 is implemented by a sensor that detects movement of an object within the notification area 100 . Also, for example, the information acquisition device 50 is realized by a microphone that acquires voice information. The information acquisition device 50 may be placed inside the notification area 100 or outside the notification area 100 as long as the information within the notification area 100 can be obtained.

The problem event detection means 22 analyzes the acquired information of the notification area 100 and detects a problem event that has occurred in the notification area 100 .

When the problem event detection means 22 detects a problem event in the notification area 100 , the problem event detection means 22 transmits to the communication means 21 a transmission instruction signal for acquiring guidance information related to the problem event from the storage 30 . The problem event detection means 22 assigns the acquired guidance information to each communication terminal 40 . For example, the problem event detection means 22 generates information combining identification information and guidance information of each communication terminal 40 as a pair.

The problem event detection means 22 outputs the guidance information assigned to each communication terminal 40 to the guidance destination notification means 23 . For example, the problem event detection means 22 outputs information regarding a combination of the identification information of each communication terminal 40 and the guidance information assigned to each communication terminal 40 to the guidance destination notification means 23 .

The guidance destination notification means 23 (also referred to as notification means) acquires the guidance information assigned to each communication terminal 40 from the problem event detection means 22 .

The communication means 31 receives a transmission instruction signal from the anomaly detection device 20 when a problem event occurs. The communication means 31 acquires guidance information corresponding to the problem event that has occurred from the guidance information storage 32 according to the received transmission instruction signal, and transmits the acquired guidance information to the abnormality detection device 20 .

The guidance information storage 32 is a storage device that acquires guidance information corresponding to problem phenomena that may occur in the notification area 100 from the communication means 31 and stores the guidance information. For example, the guidance information storage 32 stores a plurality of patterns of guidance destinations for each problem occurrence location and problem event with respect to the notification area 100 . Also, the guidance information storage 32 may store a route to a guidance destination.

The above is the description of the storage 30 .

[Guidance information table]
Here, an example of a guidance information table, which is one form of guidance information stored in the storage 30, will be described. FIG. 5 is an example of a guidance information table 320 stored in the storage 30. As shown in FIG.

The guidance information table 320 is a table that includes a plurality of patterns of guidance destinations for each problem occurrence location and problem event regarding the notification area 100 . The guidance information table 320 of FIG. 5 includes information on notification areas, problem occurrence locations, problem events, guidance destinations, and routes to guidance destinations. In the guide information table 320, the guide destination and the route to the guide destination correspond to the guide information. Note that the guidance information table 320 may include information other than the notification area, the location where the problem occurred, the problem event, the guidance destination, and the route to the guidance destination.

FIG. 7 is a flowchart for explaining the operation of the storage 30 of the notification system 1. FIG.

[Abnormality detection device]
First, the operation of the abnormality detection device 20 will be described with reference to the flowchart of FIG.

In FIG. 5, first, the anomaly detection device 20 acquires identification information and location information of each communication terminal 40 and information on the notification area 100 from the base station 10 (step S11).

The anomaly detection device 20 verifies information about the notification area 100 (step S12). For example, the anomaly detection device 20 detects problem events using advanced video analysis behavior detection technology.

When the problem event is detected in the notification area 100 (Yes in step S13), the abnormality detection device 20 transmits a transmission instruction signal instructing transmission of guidance information to the storage 30 (step S14). That is, the anomaly detection device 20 inquires of the storage 30 about guidance information using the problem occurrence location as a key. On the other hand, if the abnormality detection device 20 has not detected an abnormality in the notification area 100 (No in step S13), the process returns to step S11, and the identification information and position information of each communication terminal 40 and the information on the notification area 100 are obtained. obtained from the station 10;

The abnormality detection device 20 acquires the guidance information transmitted according to the transmission instruction signal (step S15).

The anomaly detection device 20 associates the acquired guidance information with each communication terminal 40 and transmits it to the base station 10 (step S16).

The above is the description of the operation of the abnormality detection device 20 using FIG.

[Guidance information storage]
Next, the operation of the storage 30 will be described using the flowchart of FIG.

In FIG. 6, first, the storage 30 acquires and stores guidance information corresponding to a problem phenomenon that may occur in the notification area 100 from the outside (step S21).

Upon receiving the transmission instruction signal from the abnormality detection device 20 (Yes in step S<b>22 ), the storage 30 transmits guidance information corresponding to the transmission instruction signal to the abnormality detection device 20 . On the other hand, if the storage 30 has not received the transmission instruction signal from the abnormality detection device 20 (No in step S22), the storage 30 waits for a predetermined period of time. If the storage 30 has not received the transmission instruction signal from the abnormality detection device 20 (No in step S22), the process may return to step S21 to acquire guidance information from the outside.

The above is the description of the operation of the abnormality detection device 20 using FIG.

As described above, according to the notification system 1 of the present embodiment, when a problem event occurs within the notification area, it is possible to notify an appropriate guidance destination to a communication terminal located within the notification area.

(Application example)
Here, the notification system 1 of this embodiment will be specifically described with an application example.

8 to 11 are conceptual diagrams showing an example of guiding communication terminals 40-1 to n possessed by users inside the notification area 100 to guide destinations 110-1 to 110-n (n: natural number). 8 to 11, the communication terminals 40-1 to 40-n are referred to as communication terminals 40 when they are not distinguished from each other. Similarly, the guide destinations 110-1 to 110-n are referred to as the guide destination 110 when they are not distinguished from each other.

As shown in FIG. 8 , when the notification system 1 detects a suspicious person 401 using the information received from the information acquisition device 50 , it sets a problem event area 400 around the suspicious person 401 . At this time, the notification system 1 transmits guidance information to each communication terminal 40 . That is, the notification system 1 transmits guidance information to guide the communication terminal 40 toward the guidance destination 110 so that the communication terminal 40 does not enter the problem event area 400 around the suspicious person 401 . For example, the anomaly detection device 20 assigns to the communication terminals 40 guidance conditions such that the route to the guidance destination of each communication terminal 40 does not enter the problem event area 400 . In the example of FIG. 8 , each communication terminal 40 is distributed and guided to different guidance destinations 110 .

FIG. 9 shows an example in which a suspicious person detected using information received from the information acquisition device 50 is identified by the communication terminal 40-S possessed by the suspicious person. For example, when the notification system 1 detects a suspicious person, the notification system 1 regards the communication terminal 40 located in the problem event area 400 set around the suspicious person as the communication terminal 40-S possessed by the suspicious person. Then, the notification system 1 resets the problem event area 400 in association with the identification information of the communication terminal 40-S. If the identification information of the communication terminal 40-S and the problem event area 400 are associated, when a suspicious person moves, the location information of the communication terminal 40-S is used instead of the information received from the information acquisition device 50. can identify the location of the person.

FIG. 10 is a conceptual diagram of an example of guidance when a suspicious person 401 moves within the notification area 100. As shown in FIG. In the example of FIG. 10, a suspicious person 401 moves in the direction of the arrow (rightward in FIG. 10). As the suspicious person 401 moves, the problem event area 400 set around the suspicious person 401 also moves. The anomaly detection device 20 estimates whether or not the problematic event area 400 approaches the communication terminal 40 from the position information, and assigns guidance information to the communication terminal 40 according to the approaching situation. When the problem event area 400 is approaching the communication terminal 40 , the anomaly detection device 20 notifies the communication terminal 40 of emergency information for prompt guidance to the nearby guidance destination 110 .

For example, for the communication terminals 40-3 and n whose distance from the suspicious person 401 tends to be small, the notification system 1 instructs the communication terminals 110-3 and n to move away from the suspicious person 401 urgently. Notify to evacuate immediately. For example, the notification system 1 warns that the suspicious person 401 is approaching to the communication terminals 40-1 to 40-n that tend to be closer to the suspicious person 401. FIG. In FIG. 10, the thickness of the arrow pointing from the communication terminal 40-3,n where the suspicious person 401 approaches to the guide destination 110-3,n is used to guide the communication terminal 40-2, where the suspicious person 401 does not approach. It is represented by being thicker than the arrow leading to the destination 110-2.

Further, in FIG. 10, the communication terminals 40-1 and 4, which tend to be distant from the suspicious person 401, are instructed to stand by, and the current communication terminals 40-1 and 4 are instructed to stand by. The guidance destinations 110-1 and 4 are set at the positions of . In the guidance method shown in FIG. 10, not all communication terminals 40 are guided to the guidance destination 110. Therefore, users with communication terminals 40 rushing to the entrance/exit of the notification area 100 may cause secondary damage. can be reduced.

FIG. 11 shows an example of guiding a communication terminal 40-2 possessed by a user who catches a suspicious person 401 to a problem event area 400 around the suspicious person 401. FIG. In the case of FIG. 11, the notification system 1 sets the guidance destination of the communication terminal 40-2 to the problem event area 400. In FIG. In the example of FIG. 11, the communication terminal 40-2 is notified of guidance information in which the guidance destination is set in the problem event area 400. In the example of FIG.

In the examples of FIGS. 8 to 11, the notification system 1 transmits to the communication terminal 40 guidance information including a guidance destination 110 for avoiding the problem event area 400 set around the suspicious person 401 . The user of the communication terminal 40 is distributed and guided to the guidance destination 110 according to the guidance information notified to the communication terminal 40 .

Here, an example in which the notification system of this embodiment is applied to movement of people and vehicles will be described.

FIG. 12 is a conceptual diagram showing an example of guiding a user traveling from left to right on the road inside the notification area 100 to the destination 200 so as to avoid the problem event area 400 . In the example of FIG. 12, it is assumed that the problem event area 400 is impassable due to a disaster such as an earthquake. Outside the notification area 100, the communication terminal 40 may be guided by another notification system 1 (not shown), or the communication terminal 40 may not be guided.

In order to avoid problem event area 400, notification system 1 notifies communication terminal 40-1 of guidance information for guiding to guidance destination 110-1. Also, in order to avoid the problem event area 400, the notification system 1 notifies the communication terminal 40-2 of guidance information for guiding to the guidance destination 110-2. That is, the notification system 1 notifies each communication terminal 40 of a guidance route that guides the communication terminals 40-1 and 40-2 to the destination 200 via different guidance destinations 110. FIG.

In the example of FIG. 12 , if problem event area 400 is en route to destination 200 and there are several routes to reach destination 200 , notification system 1 may provide a route avoiding problem event area 400 . is notified to the communication terminal 40 .

For example, the notification system 1 allocates the guide destinations of the communication terminals 40 according to the number of the communication terminals 40 in order to guide the user by distributing the guide destinations 110-1 and 110-2. For example, if there are ten communication terminals 40, the notification system 1 notifies five of the guide destination 110-1 and another five of the guide destination 110-2. In addition, the notification system 1 may allocate the guide destination of the communication terminal 40 according to the allowable capacity of the guide destination. For example, when the guide destination 110-2 is narrower than the guide destination 110-1, the notification system 1 notifies seven communication terminals 40 of the guide destination 110-1, and three communication terminals 40 of the guide destination 110-2. -2 may be notified.

FIG. 13 is a conceptual diagram showing an example of guiding a vehicle traveling from left to right on the road inside the notification area 100 to avoid the problem event area 400 .
