[0001] The present disclosure relates to a notification device, a system, a method, and a computer-readable medium.

Background Art

[0002] As related art, Patent Document 1 discloses a security system. In Patent Document 1, the target person to be position-detected is assumed to be an elderly person, a child, or the like. The target person carries a wireless tag integrated with a security buzzer. The wireless tag stores an ID (Identifier) for personal identification. A security surveillance camera installed on a utility pole or the like receives the ID from the wireless tag carried by the target person. When the security surveillance camera receives the ID, it transmits position detection information including the received ID to a server. The server accumulates the position detection information transmitted from the security surveillance camera to construct a database. Further, the server transmits the position detection information to the terminal of a caregiver who takes care of the target person.

[0003] When the security surveillance camera receives the ID from the wireless tag carried by the target person, it determines whether the sound input from the microphone is a sound of a predetermined value or more. When the sound input from the microphone is a sound of a predetermined value or more, the security surveillance camera determines that the security buzzer is operating. In that case, the security surveillance camera adds danger information indicating that the target person may be involved in some crime or accident to the position detection information to be transmitted to the server. When the server receives the position detection information with the danger information added, it transmits the position detection information and the danger information to the terminal of the caregiver.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In Patent Document 1, a security camera transmits danger information to a caregiver's terminal in addition to location detection information of the person being monitored when a security alarm is sounded. In this case, the caregiver can know that the person is sounding the security alarm, meaning that they may be involved in some kind of crime or accident. However, in Patent Document 1, danger information is transmitted only when the person actively sounds the security alarm. Therefore, in Patent Document 1, if a dangerous event occurs around the person that the person is unaware of, danger information will not be transmitted to the caregiver.

[0006] In view of the above circumstances, one of the purposes of this disclosure is to provide a notification device, system, method, and computer-readable medium that can notify a notification recipient that a subject is in a location related to a location where an event is occurring, even if the subject is unaware that an event is occurring. [Means for solving the problem]

[0007] To achieve the above objective, the Disclosure provides, in a first aspect, a notification device. The notification device includes event detection means for detecting that a predetermined event has occurred; location information detection means for detecting location information of a person who is the target of location detection; identification means for identifying a person who is the target of notification based on the location information of the place where the occurrence of the predetermined event was detected and the detected location information; and notification means for notifying the location information of the person identified by the identification means to the terminal of a notification recipient that is registered in association with the person identified by the identification means.

[0008] This disclosure provides, in a second aspect, a notification system. The notification system includes event detection means for detecting that a predetermined event has occurred; location information detection means for detecting location information of a person who is the target of location detection; identification means for identifying a person who is the target of notification based on the location information of the place where the occurrence of the predetermined event was detected and the detected location information; and notification means for notifying the location information of the person identified by the identification means to the terminal of a notification recipient that is registered in association with the person identified by the identification means.

[0009] This disclosure provides, in a third aspect, a notification method. The notification method includes detecting that a predetermined event has occurred, detecting the location information of a person who is the target of location detection, identifying the target person based on the location information of the place where the occurrence of the predetermined event was detected and the detected location information, and notifying the location information of the target person to the terminal of a notification recipient registered in association with the identified target person.

[0010] This disclosure provides a computer-readable medium in a fourth aspect. The computer-readable medium stores a program that causes a processor to execute a process including detecting that a predetermined event has occurred, detecting the location information of a person who is the target of location detection, identifying the target person to be notified based on the location information of the place where the occurrence of the predetermined event was detected and the detected location information, and notifying the location information of the target person to the terminal of a notification recipient registered in association with the identified target person. [Effects of the Invention]

[0011] The notification devices, systems, methods, and computer-readable media relating to this disclosure can notify a notification recipient that a subject is in a location associated with a location where an event is occurring, even if the subject is unaware that an event is occurring.

[Modes for carrying out the invention]

[0013] Prior to describing embodiments of this disclosure, an overview of this disclosure will be provided. Figure 1 shows a schematic example of the configuration of a notification device according to this disclosure. The notification device 10 includes an event detection means 11, a location information detection means 12, an identification means 13, and a notification means 14.

[0014] The event detection means 11 detects that a predetermined event has occurred. The location information detection means 12 detects the location information of the person who is the target of the location detection. The identification means 13 identifies the target person to be notified based on the location information of the place where the occurrence of the predetermined event was detected and the location information of the target person detected by the location information detection means 12. The notification means 14 notifies the location information of the identified target person to the terminal of the notification recipient that is registered in association with the identified target person.

[0015] In this disclosure, the event detection means 11 detects the occurrence of a predetermined event, and the identification means 13 identifies the target person to be notified based on the location where the predetermined event was detected and the target person's location information. In this disclosure, when the event detection means 11 detects the occurrence of a predetermined event, the target person's location information is notified to the terminal of a notification recipient registered in association with the identified target person. Therefore, in this disclosure, even if the target person is unaware that an event is occurring, the notification recipient can be notified that the target person is in a location related to the location where the event is occurring.

[0016] Hereinafter, embodiments of the present disclosure will be described in detail while referring to the drawings. Note that the following description and drawings are appropriately omitted and simplified for clarity of explanation. Also, in the following drawings, the same elements and similar elements are denoted by the same reference numerals, and duplicate explanations are omitted as necessary.

[0017] FIG. 2 shows a reporting system according to a first embodiment of the present disclosure. The reporting system 100 includes a reporting device 110, a camera 130, a user device 150, and a notification recipient terminal 170. In the present embodiment, the reporting device 110 detects that a predetermined event has occurred at a location such as an intersection. The reporting device 110 detects the position of a user who is the target of position detection. When the user exists in a location related to the location where the predetermined event has occurred, the reporting device 110 notifies the notification recipient terminal 170 used by another user related to the user that the user is in a location related to the location where the predetermined event has occurred.

[0018] The camera 130 outputs a camera image. The camera 130, for example, captures a location where people or vehicles travel, such as a road, near an intersection. The camera 130 is installed, for example, on a traffic signal or a street lamp. The camera 130 may be a surveillance camera installed at an entrance of a store or the like, or in a parking lot. Although only one camera 130 is shown in FIG. 2, the number of cameras 130 is not particularly limited to one. For example, a plurality of cameras 130 may be arranged at one intersection.

[0019] The user device 150 is a device possessed by the user to be reported, that is, the target person. The target person is, for example, a user to be monitored in a monitoring service. The target person includes, for example, children and the elderly. The user device 150 transmits predetermined information to the reporting device 110. The predetermined information includes the identification information of the user. For example, a wireless tag is used in the user device 150. The user device 150 stores the identification information of the user, that is, the target person. The user device 150 transmits the identification information to the reporting device 110 using short-range wireless communication such as Bluetooth (registered trademark).

[0020] The user device 150 is not limited to a wireless tag and may be a wireless communication device such as a smartphone possessed by the user. For example, an application for transmitting identification information to the reporting device 110 is installed on the smartphone possessed by the user. The application transmits the identification information to the reporting device 110 periodically or at the timing when communication with the reporting device 110 becomes possible.

[0021] The reporting device 110 includes an event detection unit 111, a target person detection unit 112, a specifying unit 113, and a notification unit 114. The reporting device 110 includes, for example, one or more memories and one or more processors. At least a part of the functions of each unit in the reporting device 110 can be realized by the processor operating according to a program read from the memory. The reporting device 110 corresponds to the reporting device 10 shown in FIG. 1.

[0022] The event detection unit 111 acquires camera images from the camera 130. The event detection unit 111 detects the occurrence of a predetermined event at the location where the camera 130 is installed, for example, based on the camera images. The event detection unit 111 detects events that pose a risk of harm to a target person as predetermined events. Specifically, the event detection unit 111 may detect traffic accidents, fires, or suspicious persons as predetermined events. The event detection unit 111 may also detect dangerous events that could lead to traffic accidents, such as vehicles traveling at high speed or running out of control. Furthermore, the event detection unit 111 may detect the appearance of animals that could potentially harm people, such as bears, as predetermined events. The event detection unit 111 may also detect the occurrence of a predetermined event by inputting camera images into a trained AI (Artificial Intelligence) engine, for example. The event detection unit 111 corresponds to the event detection means 11 shown in Figure 1.

[0023] The subject detection unit 112 detects the user, who is the subject, and acquires the user's location information. For example, an antenna for receiving information transmitted from the user device 150 is installed at the intersection where the camera 130 is installed. When the subject detection unit 112 receives identification information transmitted by a wireless tag at the intersection where the notification device 110 is installed, it detects the presence of the subject at the intersection. The subject detection unit 112 also acquires the location information of that intersection as the location information of the place where the subject was detected. The subject detection unit 112 may also estimate the distance from the intersection to the user device 150 based on the radio wave strength of the information transmitted from the user device 150.

[0024] Alternatively, the subject detection unit 112 may receive location information measured using GNSS (Global Navigation Satellite System) or the like from the user device 150. The subject detection unit 112 may store the acquired location information for each detected subject in a storage device (not shown). The subject detection unit 112 corresponds to the location information detection means 12 shown in Figure 1.

[0025] When the event detection unit 111 detects the occurrence of a predetermined event, the identification unit 113 identifies the person to be notified based on the location information of the place where the predetermined event occurred and the location information of the person detected by the person detection unit 112. For example, the identification unit 113 identifies a person who is in a location related to the place where the predetermined event occurred as a person to be notified. For example, the identification unit 113 may identify a person who is within a predetermined distance from the place where the predetermined event occurred as a person to be notified.

[0026] When the identification unit 113 detects the occurrence of a predetermined event at an intersection where the camera 130 is installed, it identifies the person present near that intersection as the person to be reported. For example, if the person detection unit 112 has received identification information from multiple persons at the intersection where the camera 130 is installed, the identification unit 113 may identify multiple persons as persons present near the intersection. For example, the identification unit 113 may identify persons detected by the person detection unit 112 during the period from a little before to a little after the time when the occurrence of the predetermined event was detected as persons present near the intersection.

[0027] The identification unit 113 may estimate the target's destination based on the history of the target's location information detected by the target detection unit 112. In that case, the identification unit 113 may identify the target who is estimated to be moving to the location where the occurrence of a predetermined event was detected as the target for notification. The identification unit 113 corresponds to the identification means 13 shown in Figure 1.

[0028] The notification unit 114 notifies the notification recipient terminal 170, which is registered in association with the target person identified by the identification unit 113, of the target person's location information. The notification recipient terminal 170 may be, for example, a device with communication capabilities such as a smartphone, tablet, personal computer, or dedicated terminal. The notification unit 114 transmits the target person's location information to the notification recipient terminal 170 using, for example, a communication method such as email, short message, or telephone. In addition to the location information, the notification unit 114 may also notify the notification recipient terminal 170 of the type of predetermined event that occurred.

[0029] For example, the notification unit 114 has a table that stores, for each target person, the notification recipients associated with that target person and the notification recipient terminals 170 used by those recipients. In the table, multiple notification recipients and notification recipient terminals 170 may be stored for a single target person. The notification unit 114 refers to the table, identifies the notification recipient terminals 170 associated with the identified target person, and notifies the identified notification recipient terminals 170 of the target person's location information. In addition to notifying the notification recipient terminals 170 of the target person's location information, the notification unit 114 may also notify the user device 150 possessed by the target person of the occurrence of a predetermined event. The notification unit 114 corresponds to the notification means 14 shown in Figure 1.

[0030] Next, the operating procedure will be explained. Figure 3 shows the operating procedure of the notification device 110. The operating procedure of the notification device 110 corresponds to the notification method. The subject detection unit 112 detects the subject to be monitored (step S1). In step S1, for example, if the subject detection unit 112 receives predetermined information from the user device 150 at an intersection where the camera 130 is installed, it detects the subject at that intersection.

[0031] The event detection unit 111 detects the occurrence of a predetermined event (step S2). In step S2, the event detection unit 111 detects the occurrence of a predetermined event based on, for example, a camera image acquired from the camera 130. The event detection unit 111 detects the occurrence of an event that could endanger a target person. Steps S1 and S2 may be performed in either order or in parallel.

[0032] If the occurrence of a predetermined event is detected in step S2, the identification unit 113 identifies the person to be notified (step S3). In step S3, the identification unit 113 compares, for example, the location information of the place where the occurrence of the predetermined event was detected with the location information of the person detected in step S1. The identification unit 113 identifies, for example, a person who is at the same intersection as the intersection where the occurrence of the predetermined event was detected as the person to be notified.

[0033] The notification unit 114 notifies the notification recipient terminal 170 of the notification recipient associated with the person identified in step S3 of the location information of the person (step S4). In step S4, the notification unit 114 may also notify the notification recipient that, in addition to the location information of the person, the person is near the location where a dangerous event is occurring. Upon receiving the notification, the notification recipient can, if necessary, rush to the scene or request a security company or other appropriate party to respond.

[0034] In this embodiment, the event detection unit 111 detects the occurrence of a predetermined event within the field of view of the camera 130 based on the camera image. The subject detection unit 112 detects the location information of the subject of the monitoring service based on the information transmitted from the user device 150. The identification unit 113 identifies the subject to be notified based on the location where the occurrence of the predetermined event was detected and the subject's location information. In this embodiment, for example, if the occurrence of a dangerous event is detected, the identification unit 113 can identify a subject who is near that location as the subject to be notified. The notification unit 114 notifies the notification recipient terminal 170 related to the subject to be notified of the subject's location information. In this embodiment, the subject's location information can be notified to the notification recipient terminal 170 even if the subject does not take any action. Therefore, in this embodiment, even if the subject is unaware that an event has occurred, the notification recipient can be informed that the subject is in a location related to the location where the predetermined event has occurred.

[0035] Next, a second embodiment of the present disclosure will be described. Figure 4 shows a notification system according to the second embodiment of the present disclosure. In this embodiment, the notification device 110 is connected to a plurality of cameras 130 and a plurality of information transmission units 190 via a network 180. The configuration of the notification device 110 may be the same as that of the notification device 110 described in the first embodiment shown in Figure 2. The network 180 includes, for example, a wireless communication network using a communication line standard such as a fourth-generation mobile communication system or LTE (Long Term Evolution). The network 180 may also include wireless communication networks such as WiFi®, fifth-generation mobile communication systems (5G), and local 5G.

[0036] In this embodiment, multiple cameras 130 and multiple information transmission units 190 are distributed and arranged at multiple intersections. The number of cameras 130 at each intersection is not necessarily limited to one, and multiple cameras 130 may be arranged at each intersection. Similarly, the number of information transmission units 190 at each intersection is not necessarily limited to one, and multiple information transmission units 190 may be arranged at each intersection. Furthermore, each intersection is not necessarily required to have a set of cameras 130 and information transmission units 190, and each intersection may have either a camera 130 or an information transmission unit 190.

[0037] In this embodiment, the information transmission unit 190 receives predetermined information from the user device 150 and transmits the received predetermined information to the notification device 110 via the network 180. For example, if the user device 150 is a wireless tag, the information transmission unit 190 receives identification information transmitted from the wireless tag. The information transmission unit 190 transmits the received identification information to the notification device 110 via the network 180.

[0038] The subject detection unit 112 (Figure 2) of the notification device 110 receives predetermined information from multiple information transmission units 190 via the network 180. When the subject detection unit 112 receives predetermined information, it detects the subject at the intersection where the information transmission unit 190 that transmitted the predetermined information to the notification device 110 is located. In this case, the subject detection unit 112 may also detect the location information of the intersection where the information transmission unit 190 that is the source of the information is located as the location information of the subject.

[0039] In this embodiment, each camera 130 transmits camera images to the notification device 110 via the network 180. The event detection unit 111 (see Figure 2) of the notification device 110 acquires camera images from the multiple cameras 130 via the network 180. Based on the camera images from the multiple cameras 130, the event detection unit 111 determines whether or not a predetermined event has occurred at multiple locations.

[0040] In this embodiment, the identification unit 113 identifies the person to be notified based on the location information of the place where the occurrence of a predetermined event was detected and the location information of the person detected by the person detection unit 112. For example, if the occurrence of a predetermined event is detected at a certain intersection, the identification unit 113 identifies the person present at that intersection as the person to be notified. If the occurrence of a predetermined event is detected at a certain intersection, the identification unit 113 may identify the person present at that intersection and the intersection adjacent to that intersection as the person to be notified.

[0041] In this embodiment, the identification unit 113 may track a subject across multiple intersections based on the history of the subject's location information detected by the subject detection unit 112. The identification unit 113 may also estimate the intersections to which the subject is moving based on the subject tracking results. In that case, the identification unit 113 may identify, in place of or in addition to, a subject who is present at the intersection where the predetermined event occurred, as a subject to be reported, a subject who is estimated to be moving to the intersection where the predetermined event occurred.

[0042] For example, suppose a subject is detected at intersection A, and then the same subject is detected at another intersection B. In this case, the identification unit 113 determines that the subject has moved from intersection A to intersection B. The identification unit 113 assumes that, given the geographical relationship between the intersections, the subject who moved from intersection A to intersection B is likely to then move to intersection C. In this case, the identification unit 113 estimates that the subject will move to intersection C. If the occurrence of a predetermined event is detected at intersection C, the identification unit 113 can identify the subject who is currently at intersection C, as well as the subject who is estimated to be moving to intersection C, as subjects to be reported. In this case, even if the subject is not currently at the intersection where the predetermined event was detected, the notification unit 114 can notify the notification recipient terminal 170 of the subject's location information if it is estimated that the subject will then move to the intersection where the predetermined event was detected.

[0043] In this embodiment, the notification device 110 can acquire camera images from multiple cameras 130. The notification device 110 can also acquire information transmitted from the user device 150 from multiple information transmission units 190. The notification device 110 can detect the occurrence of predetermined events at multiple intersections and can also detect the location information of target persons at multiple intersections. In this embodiment, when the occurrence of a predetermined event is detected at a certain intersection, the identification unit 113 can designate not only target persons present at that intersection, but also target persons present at intersections different from the intersection where the predetermined event was detected, as target persons for notification. Other effects are the same as those described in the first embodiment.

[0044] In each of the above embodiments, the notification device 110 does not necessarily have to be configured as a single physical device. In the first embodiment, the notification device 110 shown in Figure 2 may be configured using multiple physically separated devices. For example, the notification device 110 may be configured using devices installed at each intersection and devices installed at a location such as a data center away from the intersection. Specifically, in the first embodiment, the notification device 110 may be separated into a device having an event detection unit 111 and a target person detection unit 112, and a device having a identification unit 113 and a notification unit 114. In that case, the notification device 110 is also called a notification system.

[0045] Furthermore, in the second embodiment, the notification device 110 may be configured using a hierarchical array of server devices. Figure 5 shows an example of the configuration of a modified notification device. In this example, the notification device 110, which is a notification system, includes a higher-level server 200 and a plurality of lower-level servers 210. The higher-level server 200 is a computer device such as a cloud server. The higher-level server 200 is connected to the plurality of lower-level servers 210 via a network 180. The lower-level servers 210 may be configured as computer devices such as MEC (Multi-access / Mobile Edge Computing) servers. The lower-level servers 210 may be located at each intersection where a camera 130 (see Figure 4) is installed.

[0046] In the notification device 110 shown in Figure 5, the upper-level server 200 may include the identification unit 113 and notification unit 114 shown in Figure 2. Each lower-level server 210 may include the event detection unit 111 and target detection unit 112 shown in Figure 2. In this case, each lower-level server 210 detects the location information of a target person, for example, at an intersection. Each lower-level server 210 also detects the occurrence of a predetermined event at an intersection. The lower-level server 210 transmits the detected target person's location information and the occurrence of the detected predetermined event to the upper-level server 200. The upper-level server 200 uses the information received from the lower-level servers 210 to identify the person to be notified and notifies the identified person of their location information.

[0047] In the notification device 110 shown in Figure 5, at least some of the multiple subordinate servers 210 may have a identification unit 113 and a notification unit 114 in addition to the event detection unit 111 and the target person detection unit 112. In that case, the identification unit 113 of the subordinate server 210 may identify a target person present at the intersection where the subordinate server 210 is located as a target person to be notified when the occurrence of a predetermined event is detected at the intersection where the subordinate server 210 is located. The notification unit 114 of the subordinate server 210 notifies notification recipients related to the target person who has been identified as a target person to be notified and who is present at the intersection where the subordinate server 210 is located of the target person's location information.

[0048] On the other hand, the identification unit 113 of the upper-level server 200 may identify a person located at a different intersection from the intersection where the predetermined event occurred as a person to be reported. In that case, the notification unit 114 of the upper-level server 200 notifies the notification recipients related to the person identified as a person to be reported, who is located at a different intersection from the intersection where the predetermined event occurred, of the person's location information. When performing the above operations, each lower-level server 210 can identify the person to be reported and notify the notification recipient of their location information at the intersection where the lower-level server 210 is located. Furthermore, the upper-level server 200 can identify the person to be reported and notify the notification recipient of their location information across multiple intersections.

[0049] In the embodiments described above, an example was explained in which the event detection unit 111 detects the occurrence of a predetermined event based on the camera image of the camera 130. However, this disclosure is not limited thereto. The event detection unit 111 may, for example, detect the occurrence of a predetermined event using information acquired from a vehicle via roadside unit (RSU) using vehicle-to-infrastructure communication. Alternatively, the event detection unit 111 may detect the occurrence of a predetermined event using information acquired via a network such as the Internet from an external server that manages traffic accident information, etc.

[0050] Next, the hardware configuration of the notification device 110 will be described. Figure 6 shows an example of the configuration of a computer device that can be used in the notification device 110. The computer device 500 has a control unit (CPU) 510, a storage unit 520, a ROM (Read Only Memory) 530, a RAM (Random Access Memory) 540, a communication interface (IF: Interface) 550, and a user interface 560.

[0051] The communication interface 550 is an interface for connecting the computer device 500 to a communication network via wired communication means or wireless communication means. The user interface 560 includes a display unit, such as a display. The user interface 560 also includes input units such as a keyboard, mouse, and touch panel.

[0052] The memory unit 520 is an auxiliary storage device capable of holding various types of data. The memory unit 520 does not necessarily have to be part of the computer device 500; it may be an external storage device or cloud storage connected to the computer device 500 via a network.

[0053] ROM 530 is a non-volatile memory device. For example, a semiconductor memory device such as a relatively small-capacity flash memory is used for ROM 530. The program executed by the CPU 510 can be stored in the storage unit 520 or ROM 530. The storage unit 520 or ROM 530 stores, for example, various programs for realizing the functions of each part of the notification device 110.

[0054] The above program, when loaded into a computer, includes a set of instructions or software code for causing the computer to perform one or more of the functions described in the embodiments. The program may be stored in a non-temporary computer-readable medium or a physical storage medium. Examples, but not limited to, include RAM, ROM, flash memory, solid-state drive (SSD) or other memory technologies, Compact Disc (CD), digital versatile disc (DVD), Blu-ray® disc or other optical disc storage, magnetic cassette, magnetic tape, magnetic disk storage or other magnetic storage devices. The program may be transmitted over a temporary computer-readable medium or a communication medium. Examples, but not limited to, include, a temporary computer-readable medium or a communication medium that includes an electrical, optical, acoustic or other form of propagating signal.

[0055] RAM 540 is a volatile memory device. Various semiconductor memory devices such as DRAM (Dynamic Random Access Memory) or SRAM (Static Random Access Memory) can be used for RAM 540. RAM 540 can be used as an internal buffer for temporarily storing data. CPU 510 loads the program stored in memory unit 520 or ROM 530 into RAM 540 and executes it. By executing the program, the functions of each part of the notification device 110 can be realized. CPU 510 may have an internal buffer that can temporarily store data.
