Summary of the Invention

Problems to be Solved by the Invention

[0004] With the technology described in Patent Document 1, it was not possible to flexibly unlock the locking devices at the evacuation locations.

[0005] The present invention provides a technology for flexibly unlocking the locking devices at a predetermined location.

Means for Solving the Problems

[0006] One aspect of this disclosure includes a plurality of locking devices for locking each of a plurality of structures, and a management device for managing the plurality of locking devices. When the management device detects the occurrence of an abnormal situation in any of the plurality of structures, the management device has mode change means for changing the operation mode related to unlocking the plurality of locking devices from a first operation mode to a second operation mode among a plurality of operation modes with different unlocking authority ranges, and provides a security system.

[0007] The first operating mode may be an individual mode in which each of the multiple locking devices is unlocked with an unlocking authority set individually for each of the multiple locking devices, and the second operating mode may be an overall mode in which each of the multiple locking devices is unlocked with an unlocking authority common to all of the multiple locking devices.

[0008] Each of the plurality of structures may have a predetermined room, and the second operating mode may be configured to allow the predetermined room to be unlocked with a common key.

[0009] The second operating mode may be configured to unlock the structures based on the permission of each of the administrators of the plurality of structures.

[0010] The mode changing means may transition the operating mode from the individual mode to the overall mode if there is a person within a predetermined range based on the structure where the abnormal situation occurred.

[0011] The mode changing means may maintain the operating mode as the individual mode if there are no people within a predetermined range based on the structure where the abnormal situation occurred.

[0012] The management device may have notification means for notifying the occurrence of an abnormal situation in any of the multiple structures.

[0013] The management device may have output means that can output information that can identify which of the multiple structures is occupied by people. [Effects of the Invention]

[0014] According to the present invention, the locking device for evacuation shelters can be flexibly unlocked. [Brief explanation of the drawing]

Embodiments of the Invention

[0016] 1. Configuration FIG. 1 is a diagram illustrating the configuration of a security system S according to an embodiment. The security system S is a system for ensuring the security of an area having a plurality of structures. The security system S includes a management device 10, a network 20, imaging devices 30- 30- ···, 30-n (hereinafter collectively referred to as imaging device 30), a plurality of mobile terminals 50- 50- ···, 50-n (hereinafter collectively referred to as mobile terminal 50), and a plurality of structures 70- 70- ···, 70-n (hereinafter collectively referred to as structure 70). Each of the management device 10, the imaging device 30, the mobile terminal 50, and the structure 70 is connected and communicates with each other, either wired or wirelessly, using the network 20.

[0017] [[ID=Al]] Structure 70 is an area pre-demarcated by the person managing the security system S. Structure 70 is, for example, a detached house. Security system S is responsible for security in an area that has multiple structures 70. The area is a geographically limited area, for example, a housing complex developed as a whole, and has one or more groups. Each group consists of multiple structures 70 that are included in a certain geographical block. Each structure 70 has a common security system (security system S in this example) installed in it. Security system S manages multiple structures 70 within a group collectively and is responsible for security within that group.

[0018] Each of the structures 70 is designed to have a shelter (or evacuation room). Multiple structures 70 each have shelters 60-1, 60-2, ..., 60-n (hereinafter collectively referred to as shelter 60). Shelters 60 (corresponding to designated rooms) are spaces for protecting persons related to the area (e.g., residents living in the area). Multiple shelters 60 are locked and unlocked by locking devices 40-1, 40-2, ..., 40-n (hereinafter referred to as locking devices 40). Locking devices 40 are, for example, electric locks or smart locks, and are locked and unlocked using a designated key (e.g., a mobile terminal 50). Locking devices 40 are capable of communicating with the network 20 and lock and unlock according to operations from the mobile terminal 50 communicating with the network 20. Although not shown in the diagram, structures 70 also have locking devices in locations other than the shelters 60. Locking devices are installed, for example, on the front door or back door.

[0019] The management device 10 is a device that executes and controls various security operations within the area. The management device 10 detects abnormalities within the area. The management device 10 also manages the occupancy status of each structure 70, controls the operation of the locking device 40, generates a map to assist users in evacuation, and grants unlocking authority for the locking device 40 to the mobile terminal 50. In this example, there are multiple operating modes (including the first and second operating modes) for the operation of the locking device 40, each with a different scope of unlocking authority. The multiple operating modes include an "individual mode" (an example of the first operating mode) in which the locking devices 40 in multiple structures 70 operate with individual unlocking settings, and an "overall mode" (an example of the second operating mode) in which the locking devices 40 in multiple structures 70 operate with common unlocking settings. The management device 10 switches between these operating modes.

[0020] The individual mode is the operating mode under normal circumstances, i.e., when no abnormalities occur in the vicinity of a group (more specifically, "the vicinity of the area corresponding to the group," but here simply referred to as "the vicinity of the group") (for example, when there are no suspicious persons). When the operating mode of a group is individual mode, the locking device 40 belonging to that group operates with its own settings set by the user who manages the locking device 40 (for example, a resident of the structure 70 having the locking device 40). For example, only a key (in this example, a mobile terminal 50) owned by the user who manages the locking device 40 can unlock the locking device 40.

[0021] The global mode is the operating mode used when an abnormality occurs in the vicinity of a group (for example, when there is a suspicious person). When the operating mode of a group is global mode, the key set for global mode, for example, the key held by a user related to that group (specifically, the mobile terminal 50 held by a resident of a structure 70 belonging to that group), can unlock a predetermined locking device 40. Which locking device 40 is the predetermined locking device 40 is set by the person managing the security system S, and in this embodiment, it is the locking device 40 of all shelters 60. That is, in a group whose operating mode is global mode, the mobile terminal 50 of all users belonging to that group can unlock the locking devices 40 of all shelters 60 belonging to that group. When the operating mode of a group transitions from individual mode to global mode, unlocking authority to unlock the locking devices 40 of all shelters 60 belonging to that group is temporarily granted to all mobile terminals 50 belonging to that group. In this way, the security system S can prompt the user to evacuate to a different structure 70 (for example, a different house from the user's own home) by temporarily granting unlocking authority to the user's mobile terminal 50.

[0022] The camera 30 is a camera that monitors the area, particularly the structure 70 and its surroundings. The camera 30 is a device for detecting suspicious persons within the area and is positioned at various locations within the area to ensure thorough coverage. The camera 30 is constantly recording for the security of the area. The video captured by the camera 30 is output to the management device 10 for the purpose of detecting anomalies within the area (for example, detection of suspicious persons).

[0023] The mobile terminal 50 is a device (e.g., a smartphone) owned by a user of the security system S. The mobile terminal 50 obtains various information related to security in the area from the management device 10. For example, if a suspicious person appears in the area, the mobile terminal 50 obtains a map from the management device 10 for the user of the mobile terminal 50 to evacuate. The mobile terminal 50 has a security application installed. The security application is provided, for example, by the manufacturer of the locking device 40. Through user operation, the mobile terminal 50 associates the user ID and structure ID described later on the security application. Following the user's operation of the security application, the mobile terminal 50 locks and unlocks the locking device 40 via the network 20. The mobile terminal 50 also notifies the management device 10 of the discovery of a suspicious person, following the user's operation of the security application. The mobile terminal 50, which has the security application logged in using a user ID that can uniquely identify a resident, locks and unlocks the locking device 40 according to the operating mode of the locking device 40.

[0024] Figure 2 illustrates the functional configuration of the management device 10. The management device 10 includes a storage means 201, a mode changing means 202, a notification means 203, an output means 204, and a control means 205.

[0025] The control means 205 controls various operations. When the mode change means 202 detects an abnormal situation in any of the multiple structures, it transitions the operation mode for unlocking the multiple locking devices from an individual mode, where each of the multiple locking devices is unlocked with unlocking authority set individually for each of the multiple locking devices, to an overall mode, where each of the multiple locking devices is unlocked with unlocking authority common to all of the multiple locking devices. Furthermore, if there is a person within a predetermined range based on the structure where the abnormal situation occurred, the mode change means 202 transitions the operation mode from the individual mode to the overall mode. Furthermore, if there is no person within the predetermined range based on the structure where the abnormal situation occurred, the mode change means 202 maintains the operation mode in the individual mode. Note that the operation mode of the security system S is managed and set for each group, i.e., each area.

[0026] Notification means 203 notifies of the occurrence of an abnormal situation in any of the multiple structures. Output means 204 outputs information that can identify the structure in which people are present among the multiple structures. Storage means 201 stores the security application program and database.

[0027] Figure 3 illustrates the hardware configuration of a management device 10 according to one embodiment. The management device 10 is a computer device having a CPU (Central Processing Unit) 101, memory 102, storage 103, and a communication IF (Interface) 104. The CPU 101 is a processor that executes programs, performs various calculations, and controls other hardware elements of the management device 10. The memory 102 is a main memory that functions as a work area when the CPU 101 executes programs. The storage 103 is a non-volatile auxiliary memory that stores various programs and data. The communication IF 104 is a communication device that communicates with other devices according to a predetermined communication standard (e.g., Ethernet®).

[0028] In this example, storage 103 stores a program (hereinafter referred to as the "management device program") that causes the computer device to function as a management device 10 in the security system S. The CPU 101 executes the management device program, thereby implementing the functions shown in Figure 2 in the computer device. While the CPU 101 is executing the management device program, at least one of memory 102 and storage 103 is an example of storage means 201, the CPU 101 is an example of mode change means 202 and control means 205, and communication IF 104 is an example of notification means 203 and output means 204.

[0029] Figure 4 illustrates the hardware configuration of a mobile terminal 50 according to one embodiment. The mobile terminal 50 is a computer device having a processor 501, memory 502, interface 503, communication unit 504, output unit 505, input unit 506, and positioning system 507. These components are connected to each other in a communicative manner, for example, by a bus.

[0030] The processor 501 controls various parts of the mobile terminal 50 by reading and executing computer programs (hereinafter simply referred to as "programs") stored in the memory 502. The processor 501 is, for example, a CPU (Central Processing Unit). The memory 502 is a storage means that stores the operating system, various programs, data, etc., that are loaded into the processor 501. The memory 502 stores the security application program. The memory 502 has RAM (Random Access Memory) and ROM (Read Only Memory). The memory 502 may also have a solid-state drive, a hard disk drive, etc. The interface 503 is a communication circuit that enables communication between the processor 501 and the communication unit 504, output unit 505, input unit 506, and positioning system 507. The communication unit 504 controls communication with the management device 10 via the network 20. The output unit 505 consists of a display unit such as a display and an audio output unit such as a speaker, and outputs images, characters, or sounds. Specifically, in this embodiment, the output unit 505 is composed of a display 5051. The display 5051 is composed of a flat panel display such as a liquid crystal display or an organic EL display, or a spatial display, and outputs images or characters. In addition to visual or auditory output, the output unit 505 may also provide tactile output such as vibration. The input unit 506 is an operation unit consisting of a keyboard or mouse, and inputs various information according to the user's instructions. In this embodiment, the input unit 506 consists of a touch panel 5061 and a microphone 5062. The touch panel 5061 is an electronic component such as a touchpad that combines a position input device with a display 5051, which is a flat panel display, and is an input device that allows the user to operate the device by touching the display area on the screen. The microphone 5062 converts the user's voice into a digital signal. The voice input to the microphone 5062 can be used for voice recognition processing in the processor 501. The positioning system 507 is, for example, a satellite positioning system such as GPS (Global Positioning System), and is a system for measuring the current position on Earth.

[0031] 2.Operation 2.1 Example 1 Figure 5 is a diagram illustrating the outline of the unlocking process (Example 1). Figure 5 illustrates the flow of Example 1 in three stages. In Figure 5, the operating mode transitions in the order of individual mode 51, overall mode 52, and individual mode 53. First, if there are no suspicious persons around the group, the operating mode for that group is individual mode 51, and the monitoring mode of each structure 70 is monitoring. When the presence of a suspicious person is confirmed, the operating mode transitions to overall mode 52. At this time, the monitoring mode of the structure 70 closest to the suspicious person transitions to abnormal, and the monitoring modes of the other structures 70 in the group transition to alert. When the resident in the structure 70 corresponding to the location where the suspicious person was confirmed has completed evacuation to the shelter 60 of the nearest structure 70 from the structure 70 they are currently in, the operating mode transitions to individual mode 53. When the operating mode is individual mode 53, the monitoring mode maintains the same mode as when the operating mode was overall mode 52. Subsequently, at any time, the monitoring mode of all structures 70 will transition to monitoring mode, according to the actions of the residents or the user of the security system S.

[0032] Figures 6 and 7 are sequence charts illustrating the operation of the unlocking process. The operation of Embodiment 1 will be explained using Figures 6 and 7. In Embodiment 1, when an intruder enters structure 70-1 while residents are present, the management device 10 transitions the operating mode of the locking devices 40 of all shelters 60 in the group from individual mode to global mode. The residents of structure 70-1 unlock the locking devices 40 of structures 70 other than the structure they own and take refuge in shelter 60 (shelter 60-2 in this example). In step S601, the management device 10 changes the monitoring mode and the operating mode.

[0033] Figure 8 is a flowchart illustrating the operation of the mode change process (step S601) in the management device 10. In step S6011, the management device 10 determines whether a suspicious person has been detected. A suspicious person is, for example, a person who has been in front of the entrance of the structure 70 for a predetermined amount of time, or a person who has entered the structure 70 from a location other than the entrance (e.g., a window). Suspicious people are detected based on the video output from the camera 30. The camera 30 is constantly taking pictures and outputs the captured video to the management device 10. The management device 10 uses the background subtraction method or the like on the acquired video to measure the time a person stays in the predetermined area in front of the entrance. The management device 10 stores a layout map 900 that shows the arrangement of each structure 70 and the location of the camera 30 in the area, and can identify the location of the suspicious person captured by the camera 30 on the layout map 900. The management device 10 also stores a structure ID that identifies each structure 70, linked to the arrangement of each structure 70. The structure ID is an identification number uniquely assigned to each structure 70. Therefore, the management device 10 can identify which structure ID corresponds to which structure 70 the intruder is inside or near. If the intruder is not inside a particular structure 70 but is between multiple structures 70, then the device can identify one of those multiple structures 70 that is closest to the intruder, or some (two or more) or all of those multiple structures 70.

[0034] Figure 9 is an example of a layout map 900. The layout map 900 is a map of a group having four structures 70, indicated by structures 9011 to 9014, and shows the arrangement of each structure 70. Structure 9011 has an entrance 902, a shelter 903, and a back entrance 904. The arrangements of the entrance, shelter, and back entrance in structures 9012 to 9014 are the same as those in structure 9011, so no explanation is given. Icons 9051 to 9055 (hereinafter collectively referred to as icons 905) indicate the location of the camera 30 and correspond to the location of the camera 30 in real space.

[0035] Returning to the explanation of Figure 8, if a suspicious person is detected in step S6011, the process proceeds to step S6012. If no suspicious person is detected in step S6011, the process remains at step S6011. In step S6012, the management device 10 reads the settings database 1000 and the occupancy status database 1100.

[0036] Figure 10 illustrates the configuration database 1000. The configuration database 1000 stores various settings related to the monitoring of structures 70 within a group. The configuration database 1000 includes structure ID 1001, monitoring mode 1002, operation mode 1003, and user ID 1004. Structure ID 1001 is an ID that uniquely identifies structure 70. User ID 1004 is an ID for uniquely identifying residents and is linked to structure ID 1001. User ID 1004 linked to structure ID 1001 is, for example, an ID held by a resident of structure 70 corresponding to structure ID 1001. Residents can lock and unlock their homes (structure 70 in this example) using a mobile terminal 50. A mobile terminal 50 corresponding to user ID 1004 linked to structure ID 1001 can unlock the locking device 40 of structure 70 corresponding to structure ID 1001, regardless of the operating mode 1003.

[0037] Monitoring mode 1002 is a setting related to the monitoring of structure 70. Monitoring mode 1002 can be, for example, "Monitoring," "Abnormal," or "Alert." "Monitoring" is the monitoring mode 1002 for a structure 70 when there are no suspicious persons in the area including that structure 70. If monitoring mode 1002 is "Monitoring" in all records, the camera 30 takes video in real time. In this case, the camera 30 outputs the captured video to the management device 10, but does not record the video. The camera 30 may record (at least some) of the video. "Abnormal" is the monitoring mode 1002 when there is a suspicious person inside or around a structure 70. If there is at least one record where monitoring mode 1002 is "Abnormal," the camera 30 not only takes video in real time and outputs the captured video, but also records the captured video. For records where monitoring mode 1002 is "abnormal", the mobile terminal 50 corresponding to user ID 1004 is periodically notified that there is a suspicious person inside or around a certain structure 70. "Alert" is monitoring mode 1002 when there is another structure 70 in the area where monitoring mode 1002 is "abnormal". For records where monitoring mode 1002 is "Alert", the mobile terminal 50 corresponding to user ID 1004 is periodically notified that there is a suspicious person in the area.

[0038] Operation mode 1003 is a setting relating to the unlocking authority of the locking device 40. Operation mode 1003 can be, for example, "individual" or "general". For a locking device 40 of a structure 70 where operation mode 1003 is "individual", only a mobile terminal 50 corresponding to a user ID 1004 included in the same record as the structure ID 1001 of that structure 70 in the setting database 1000 can unlock the locking device 40. For example, for a locking device 40 of a structure 70 where the structure ID 1001 is "001", only a mobile terminal 50 whose user ID 1004 is "001a", "001b", or "001c" can unlock it.

[0039] If even one structure 70 has transitioned to "abnormal" in monitoring mode 1002, the operation mode 1003 of the configuration database 1000 transitions to "overall". The locking device 40 of a structure 70 whose operation mode 1003 is "overall" can be unlocked by any mobile terminal 50 that corresponds to user ID 1004 in the configuration database 1000. In other words, a user can use their mobile terminal 50 to unlock the locking device 40 of a structure 70 other than the structure 70 they own (for example, another house other than their own).

[0040] If the monitoring mode 1002 of all structures 70 within a group is set to "Monitoring," the operation mode 1003 is "Individual." However, if the monitoring mode 1002 of any of the structures 70 within the area transitions to "Abnormal," the operation mode 1003 transitions to "Overall" in order to evacuate users of the structure 70 whose monitoring mode 1002 is "Abnormal" to the shelters 60 of the other structures 70. In addition, in structures 70 other than the structure 70 whose monitoring mode 1002 is "Abnormal," even if there are no suspicious persons present, the monitoring mode 1002 transitions to "Alert" as a precaution against the presence of suspicious persons in the vicinity. For example, if the monitoring mode 1002 of a record with structure ID 1001 "001" transitions to "Abnormal," the monitoring mode 1002 of all other records transitions to "Alert," and the operation mode 1003 transitions to "Overall." Furthermore, a mobile terminal 50 whose user ID 1004 is "001a", "001b", or "001c" can unlock the locking device 40 of the shelter 60 of a structure 70 other than the structure 70 whose structure ID 1001 is "001" (for example, the structure 70 whose structure ID is "002").

[0041] Figure 11 illustrates the occupancy status database 1100. The occupancy status database 1100 is a database that stores the occupancy status of residents within a group. The occupancy status database 1100 includes user ID 1101 and occupancy status 1102. User ID 1101 is an ID shared with user ID 1004 to uniquely identify a resident. Occupancy status 1102 indicates the occupancy status of the resident with user ID 1101 in the same record. For each record, occupancy status 1102 stores either "occupied" or "absent". The determination of whether a resident is at home or absent is based on whether the locking device on the front door has been unlocked. For example, if the locking device 40 is unlocked from outside the structure 70 (i.e., outside the house), the locking device 40 transmits to the management device 10 the user ID 1101 corresponding to the mobile terminal 50 used to unlock it, and a signal indicating that the resident is at home. Furthermore, the management device 10 switches the home status 1102 corresponding to the acquired user ID 1101 to "home". If the locking device 40 is unlocked from inside the structure 70 (i.e., inside the house), the locking device 40 transmits to the management device 10 the user ID 1101 corresponding to the mobile terminal 50 used for unlocking, and a signal indicating absence. The management device 10 also switches the home status 1102 corresponding to the acquired user ID 1101 to "absent". Regarding the locking device 40, in this example, key reading devices are provided in two locations, on the outside and inside of the entrance. If the unlocking operation, i.e., key reading, is performed from the outside, it is determined that the door was unlocked from the outside (i.e., the person returned home), and if the unlocking operation is performed from the inside, it is determined that the door was unlocked from the inside (i.e., the person went out). Note that the determination of whether the unlocking of the locking device 40 was performed from outside or inside the structure 70 may also be made by other methods, such as operator recognition by camera.

[0042] Returning to the explanation of Figure 8, in step S6013, the management device 10 changes the monitoring mode 1002 of the configuration database 1000. For example, if the management device 10 detects in step S6011 that an intruder has entered structure 70 whose structure ID 1001 is "001", it changes the monitoring mode 1002 of the record whose structure ID 1001 is "001" to "abnormal". The management device 10 also changes the monitoring mode 1002 of records other than the record whose structure ID 1001 is "001" to "alert".

[0043] In step S6014, the management device 10 notifies all mobile terminals 50 corresponding to user ID 1004 in the configuration database 1000 of the change in monitoring mode. Specifically, the display 5051 of the mobile terminal 50 corresponding to user ID 1004 in the same record as structure ID 1001 whose monitoring mode 1002 has transitioned to "abnormal" displays the message "Monitoring mode has become abnormal." This display process is performed at predetermined intervals while monitoring mode 1002 is "abnormal". In addition, the display 5051 of the mobile terminal 50 corresponding to user ID 1004 in the same record as structure ID 1001 whose monitoring mode 1002 has transitioned to "alert" displays the message "Monitoring mode has become alert." This display process is performed at predetermined intervals while monitoring mode 1002 is "alert".

[0044] In step S6015, the management device 10 identifies the residents of the target structure (hereinafter referred to as the target structure) who are inside or around the structure identified in step S6011. Whether a resident of the target structure is inside the target structure is determined by referring to, for example, the occupancy status database 1100. Residents corresponding to user ID 1101 whose occupancy status 1102 is "at home" are determined to be inside the target structure. Residents corresponding to user ID 1101 whose occupancy status 1102 is "absent" are determined to be not inside the target structure. Whether a resident of the target structure is in the vicinity of the target structure is determined based on the location information of the resident's mobile terminal 50. For example, the management device 10 obtains the current location from the mobile terminal 50 of user ID 1004 corresponding to the target structure whose occupancy status 1102 is "absent". If the acquired current location is within a predetermined range from the target structure, it is determined that the resident corresponding to the mobile terminal 50 is in the vicinity of the target structure. If the acquired current location is not within a predetermined range from the target structure, it is determined that the resident corresponding to the mobile terminal 50 is not in the vicinity of the target structure. If it is determined that there is one or more residents of the target structure inside or around the target structure, the process proceeds to step S6016. If it is determined that there are no residents of the target structure inside or around the target structure, the mode change process ends, and the process proceeds to step S602.

[0045] In step S6016, the management device 10 changes the operating mode 1003 of the configuration database 1000 to "All". In step S6017, the management device 10 notifies all mobile terminals 50 corresponding to user ID 1004 in the configuration database 1000 of the change in operating mode. Specifically, it displays the message "The operating mode has been changed to All." on the display 5051 of the mobile terminal 50. After notifying the mobile terminals 50 of the change in operating mode, the management device 10 terminates the mode change process and proceeds to step S602.

[0046] Returning to the explanation of Figures 6 and 7, in step S602, the control device 10 notifies the locking device 40-1 that the operating mode has been changed to "whole". The locking device 40-1 receives the notification that the operating mode has been changed to "whole".

[0047] In step S603, the locking device 40-1 switches its unlocking authority in accordance with the change in operating mode to "overall". Specifically, the locking device 40-1 switches its unlocking authority so that the mobile terminal 50 corresponding to the user ID included in the database that indicates user IDs with unlocking authority when the operating mode is "overall" (hereinafter referred to as the overall mode database; not shown) can unlock the locking device 40-1. Each locking device 40 stores a database that indicates user IDs with unlocking authority when the operating mode is "individual" (hereinafter referred to as the individual mode database), and an overall mode database (not shown). Specifically, for example, the locking device 40-1 stores user IDs corresponding to residents of structure 70-1 in the individual mode database. While the operating mode is "individual", the locking device 40-1 operates according to the individual mode database. In other words, while the operating mode is "individual," only the mobile terminal 50 corresponding to the user ID included in the individual mode database (in this example, the mobile terminal 50 owned by the residents of structure 70-1) can unlock the locking device 40-1. The locking device 40-1 also stores in the global mode database all the user IDs of the residents of structure 70 that belong to the same group as structure 70-1. While the operating mode is "global," the locking device 40-1 operates according to the global mode database. In other words, while the operating mode is "global," all the mobile terminals 50 corresponding to the user ID included in the global mode database (in this example, the mobile terminals 50 of all residents in the group) can unlock the locking device 40-1.

[0048] In step S604, the management device 10 notifies the locking device 40-2 that the operating mode has been changed to "overall". The locking device 40-2 receives the notification that the operating mode has been changed to "overall". In step S605, the locking device 40-2 switches its unlocking authority in accordance with the change in operating mode to "overall". Specifically, the locking device 40-2 switches its unlocking authority so that mobile terminals 50 having user IDs included in the overall mode database can unlock the locking device 40-2. The management device 10 also notifies the locking devices 40 other than locking devices 40-1 and 40-2 of the change in operating mode. The locking devices 40 that receive the notification switch their unlocking authority so that mobile terminals 50 having user IDs included in the overall mode database can unlock the locking device 40, similar to locking devices 40-1 and 40-2.

[0049] In step S606, the management device 10 generates an evacuation map 1200 to be displayed on the evacuee's mobile terminal 50. An evacuee is a person identified in step S6016 who is inside or near the target structure. The evacuation map 1200 is a map for evacuating evacuees to a shelter 60 in a different structure 70 than the structure 70 in which they are currently located.

[0050] Figure 12 is an example of the evacuation map 1200. The evacuation map 1200 is a map in which icons 1201, arrows 1202, and icon 1209 are superimposed on the layout map 900. Structures 1204 and 1205 are both in a state where the residents of the structure 70 are absent, and are displayed with the word "Absent". Structure 1208 is in a state where the residents of the structure 70 are at home, and is displayed with the word "At Home". Structure 1206 is the home of an evacuee, and is displayed with the word "Home".

[0051] Icon 1201 indicates the location of the suspicious person detected in step S601. The location of icon 1201 on the map corresponds to the location of the suspicious person in real space. When the camera 30 detects the movement of the suspicious person, the location of icon 1201 on the map also changes. Icon 1209 indicates the location of the evacuee's mobile device 50. The location of the evacuee's mobile device 50 is determined using the positioning system 507. The location of icon 1209 on the map corresponds to the location of the evacuee in real space. As the location of the evacuee's mobile device 50 in real space changes, the location of icon 1209 also changes.

[0052] Arrow 1202 indicates the route from the current location of the evacuee's mobile device 50 (i.e., icon 1209) to shelter 1203. The starting point of arrow 1202 corresponds to the current location of the evacuee's mobile device 50, and the ending point of arrow 1202 corresponds to the shelter 1203, the evacuation destination. Arrow 1202 is a straight line and represents a simplified route. Shelter 1203 has a door 1207. When a resident opens door 1207, the evacuee can be protected by that resident. In the evacuation map 1200, the shelter 60 of the nearest other structure 70 (shelter 1203 in this example) from the current location of the evacuee's mobile device 50 is indicated as the evacuation destination. In addition, since the evacuee's mobile device 50 also has the authority to unlock the locking devices 40 of other shelters 60 in the same group, it is also possible to evacuate to the shelter in structure 1205 or the shelter in structure 1208.

[0053] Returning to the explanation of Figures 6 and 7, in step S607, the management device 10 transmits the evacuation map 1200 generated in step S606 to the evacuee's mobile terminal 50. The evacuee's mobile terminal 50 receives the evacuation map 1200 from the management device 10.

[0054] In step S608, the display 5051 of the evacuee's mobile terminal 50 displays the evacuation map 1200 received in step S607. The evacuation map 1200 is displayed, for example, on a security app. The displayed evacuation map 1200 is updated to the latest version as the evacuee's mobile terminal 50's current location changes. Also, if the camera 30 detects the movement of a suspicious person, the displayed evacuation map 1200 is updated to the latest version. Therefore, the processing in steps S606 to S608 is repeated until the processing in step S609 is executed.

[0055] In step S609, the evacuee's mobile device 50 unlocks the locking device 40 of the shelter 60 (in this example, the locking device 40-2 of shelter 60-2). Specifically, the evacuee first activates a security app on the mobile device 50. The mobile device 50 communicates with the locking device 40-2. When the mobile device 50, with the security app activated, approaches the locking device 40-2, the locking device 40-2 is unlocked. Once the locking device 40-2 is unlocked, the evacuee can open the door to shelter 60-2 and enter shelter 60-2. The locking device 40-2 locks itself when it is unlocked from the outside by the evacuee's mobile device 50 and locked from the inside of the door. By being locked, it is possible to prevent intruders from entering shelter 60-2.

[0056] In step S610, the locking device 40-2 notifies the management device 10 that the evacuation is complete. When the locking device 40-2 is unlocked and then locked while the operating mode is set to "overall", the management device 10 determines that the evacuation of evacuees is complete. The management device 10 receives a notification from the locking device 40-2 indicating that the evacuation is complete. In step S611, the management device 10 updates the configuration database 1000. Specifically, it changes the monitoring mode 1002 to "monitoring" for all records except the record containing the structure ID 1001 corresponding to the target structure. The management device 10 also changes the operating mode 1003 to "individual". The monitoring mode 1002 for the record corresponding to the target structure remains "abnormal". When the safety of the target structure is confirmed by the residents of the target structure, the monitoring mode 1002 changes to "monitoring" via the operation of a mobile terminal 50 by the residents. Furthermore, if the safety of the target structure is confirmed by a person managing the security system S, such as a security guard, the monitoring mode 1002 may transition to "monitoring" via operation of the management device 10 by the security guard.

[0057] In step S612, the management device 10 notifies all mobile terminals 50 corresponding to user ID 1004 in the configuration database 1000 that the operating mode has been changed to "individual". Specifically, it displays the message "Operating mode has been changed to individual." on the display 5051 of the mobile terminal 50. The management device 10 also notifies mobile terminals 50 of residents of structures other than the target structure that the monitoring mode has been changed to "monitoring". Specifically, it displays the message "Monitoring mode has been changed to monitoring." on the display 5051 of the mobile terminal 50. The mobile terminal 50 receives various notifications.

[0058] In step S613, the control device 10 notifies the locking device 40-1 that the operating mode has been changed to "individual". The locking device 40-1 receives the notification that the operating mode has been changed to "individual".

[0059] In step S614, the locking device 40-1 switches its unlocking authority in accordance with the change in operating mode to "individual". Specifically, the locking device 40-1 switches its unlocking authority so that a mobile terminal 50 having a user ID included in the individual mode database can unlock the locking device 40-1.

[0060] In step S615, the control device 10 notifies the locking device 40-2 that the operating mode has been changed to "individual". The locking device 40-2 receives the notification that the operating mode has been changed to "individual".

[0061] In step S616, the locking device 40-2 switches its unlocking authority in accordance with the change in its operating mode to "individual". Specifically, it switches its unlocking authority so that the locking device 40-2 and the mobile terminal 50 having a user ID included in the individual mode database can unlock the locking device 40-2. The management device 10 also notifies the other locking devices 40, besides locking devices 40-1 and 40-2, of the change in operating mode. Upon receiving the notification, the locking device 40 switches its unlocking authority, similar to locking devices 40-1 and 40-2, so that the mobile terminal 50 having a user ID included in the individual mode database can unlock the locking device 40.

[0062] In this way, since the detection of suspicious persons is performed based on the images captured by the camera 30, evacuees can quickly evacuate outside their own structure even if they are unaware of the presence or location of the suspicious person. Furthermore, by switching the operating mode to the overall mode, evacuees can evacuate to a shelter 60 in a different structure 70 from the one where the suspicious person is located.

[0063] 2.2 Example 2 Figure 13 illustrates an overview of the unlocking process (Example 2). Figure 13 illustrates the flow of Example 2 in three stages. Example 2 differs from Example 1 in the following respects. First, the suspicious person is not detected based on the video captured by the camera 30, but rather detected when the management device 10 receives a notification of the discovery of a suspicious person from the evacuee's mobile terminal 50. Also, the process in step S601 may be triggered when the management device 10 obtains suspicious person information indicating information related to the occurrence of a suspicious person from another server (not shown). Furthermore, the management device 10 does not generate a map to guide the evacuee to the shelter 60 of the nearest structure 70, but rather generates a map to guide the evacuee to the shelter 60 of the nearest structure 70 among the structures 70 in which other residents are present. These are the differences from Example 1. Note that the administrator of the security system S may pre-configure which unlocking process, Example 1 or Example 2, is applied to operate the security system S. Furthermore, both embodiments may be used in combination, such as employing detection using the camera device 30 and detection using the mobile terminal 50 as methods for detecting suspicious persons.

[0064] In Example 2, the system operates in principle according to the sequence charts shown in Figures 6 and 7, and the flowchart shown in Figure 8. The following describes the process that differs from Example 1. In step S6011, the management device 10 detects a suspicious person after receiving a notification of the discovery of a suspicious person from the evacuee's mobile terminal 50. Specifically, for example, the evacuee launches a security application on their mobile terminal 50 and selects a button (not shown) on the security application indicating that a suspicious person has been discovered. The notification of the discovery of a suspicious person includes the user ID 1004 corresponding to the evacuee's mobile terminal 50 and the location information of the evacuee's mobile terminal 50.

[0065] In step S6013, the management device 10 changes the monitoring mode 1002. For example, if in step S6011 the structure ID 1001 corresponding to the evacuee's user ID 1004 is "001", the management device 10 changes the monitoring mode 1002 of the record where the structure ID 1001 is "001" to "abnormal". The management device 10 also changes the monitoring mode 1002 of records other than the record where the structure ID 1001 is "001" to "alert". It also changes the operation mode 1003 to "overall".

[0066] In step S606, the management device 10 generates an evacuation map 1400 to be displayed on the evacuee's mobile terminal 50. The evacuation map 1400 is a map for evacuating evacuees to shelters 60 in other structures 70 where people are present.

[0067] Figure 14 is an example of the evacuation map 1400. The evacuation map 1400 is a map in which icons 1401 and arrows 1402 are superimposed on the layout map 900. Structures 1406 and 1407 both indicate that the user of the structure is at home and are displayed with the words "At Home". Structure 1408 indicates that the user is absent and is displayed with the words "Absent". Structure 1405 indicates that the evacuee's home and is displayed with the words "Home".

[0068] Icon 1401 indicates the location of the evacuee's mobile device 50. The location of the evacuee's mobile device 50 is determined using a positioning system 507. The location of icon 1401 on the map corresponds to the evacuee's location in real space. As the location of the evacuee's mobile device 50 changes in real space, the location of icon 1401 also changes. Arrow 1402 indicates the route from the current location of the evacuee's mobile device 50 (i.e., icon 1401) to shelter 1404. The starting point of arrow 1402 corresponds to icon 1401, and the ending point of arrow 1402 corresponds to shelter 1404, the destination. Arrow 1402 is a straight arrow and only shows a simplified route. Shelter 1404 has a door 1403. When a user who is at home opens door 1403, the evacuee can be protected by that user. Furthermore, since the evacuee's mobile device 50 also has the authority to unlock the locking devices 40 of other shelters 60 within the same group, they can also evacuate to the shelter in structure 1407 or the shelter in structure 1408.

[0069] Thus, because the detection of suspicious persons is based not on images captured by the camera 30, but on notifications of the discovery of suspicious persons by evacuees' mobile terminals 50, even in configurations where the camera 30 is not installed in the area, evacuees can take refuge in a shelter different from their own structure. Furthermore, since evacuees are guided to the shelter 60 of the structure 70 where people are present, they can be protected by people immediately after evacuating.

[0070] 3. Variant The present invention is not limited to the embodiments described above, and various modifications are possible. Several modifications are described below. Two or more of the modifications described below may be used in combination.

[0071] 3-1. Elements of the Example Some of the details described in Example 1 may be adopted in Example 2, and some of the details described in Example 2 may be adopted in Example 1. For example, in Example 1, the detection of a suspicious person may not be based on the video captured by the camera 30, but rather, as in Example 2, be detected when the management device 10 receives a notification of the discovery of a suspicious person from the evacuee's mobile terminal 50.

[0072] 3-2. Detection of suspicious persons The detection of a suspicious person in step S6011 is not limited to being based on video footage captured by the camera 30 or notification from an evacuee; for example, a sensor without an imaging unit (e.g., a so-called home security system) may also detect the suspicious person. The sensor may be, for example, a door or window opening / closing sensor, a motion detection sensor, or a glass breakage detection sensor.

[0073] 3-3. Conditions for Mode Switching The conditions for switching the operating mode from individual mode to global mode are not limited to when a suspicious person is detected within the group, but may also be when other abnormal situations are detected within the group. Other abnormal situations include, for example, when the camera 30 detects an external impact, when the camera 30 is covered (i.e., the image becomes completely dark), or when there is a fire. In addition, the operating mode may be switched from individual mode to global mode if the camera 30 or the like detects a number of people greater than the number of visitors that the residents have registered in advance.

[0074] Switching between the operating mode and the monitoring mode is not limited to being performed automatically when conditions are met, such as when an abnormal situation is detected; it may also be performed manually by a resident or the person managing the security system S.

[0075] If the monitoring mode of structure 70 was set to "alert," the monitoring mode may not remain "alert" even after the evacuees have completed their evacuation, but may instead transition to "monitoring" as soon as the evacuees have completed their evacuation.

[0076] 3-4. Transition of Operating Modes If there are other structures 70 whose monitoring mode 1002 has transitioned to "abnormal," the operation mode 1003 of the own structure is not necessarily limited to transitioning to "overall." For example, if a particular user is an evacuee, a setting may be made in advance for each structure 70 to prevent the operation mode 1003 from transitioning to "overall" and to keep the operation mode 1003 in "individual" mode in order to not accept the evacuation of that evacuee.

[0077] 3-5. Unlocking Permissions in Global Mode In the overall mode, the locking device that can be unlocked with temporary unlocking authority (i.e., the device to which unlocking authority is granted) is not limited to the locking device 40 of the shelter 60, but may be, for example, the locking device of the back door or the front door. In another example, multiple candidate locking devices to be unlocked with unlocking authority may be defined, and among these, locking devices that meet certain conditions may be identified as the locking devices to be unlocked with temporary unlocking authority. In one example, a sensor is associated with each of these multiple locking devices, and if an anomaly is detected by a sensor, the locking device corresponding to that sensor is identified as the device to which unlocking authority is granted. Unlocking authority can be granted to this locking device remotely, for example, allowing a resident to check the location of the anomaly.

[0078] 3-6. Mobile devices that grant temporary unlocking privileges The mobile terminal 50 that obtains temporary unlocking authority in overall mode is not limited to the evacuee's mobile terminal 50, but may also be, for example, a mobile terminal 50 corresponding to another user ID 1004 in the record having the user ID of the evacuee's mobile terminal 50 (for example, a mobile terminal 50 of a person living with the evacuee).

[0079] 3-7. Expiration of temporary unlocking privileges The timing at which the temporary unlocking authority expires is not limited to the time when the locking device 40 is unlocked using the temporary unlocking authority. For example, the temporary unlocking authority may expire after a predetermined time, such as 10 minutes.

[0080] 3-8. Determining the presence of residents at home The presence or absence of a resident is not limited to being determined based on whether the front door lock has been unlocked, but may also be determined based on, for example, whether the resident's mobile device is connected to the network 20 of the structure 70. Specifically, when the mobile device 50 connects to the network 20 of the structure 70 (e.g., Wi-Fi), it transmits the user ID 1101 corresponding to the mobile device 50 and a signal indicating that the resident is present to the management device 10. When the mobile device 50 loses its connection to the network 20 of the structure 70, it transmits the user ID 1101 corresponding to the mobile device 50 and a signal indicating that the resident is absent to the management device 10 using a network 20 other than the structure 70. In other words, the presence or absence of a resident is determined by whether the mobile device 50 owned by the resident is connected to the network 20 of the resident's structure 70 (i.e., the resident's home). The presence status database 1100 is updated when the user ID 1101 and signal are obtained from the mobile device 50. Furthermore, for example, the presence or absence of a resident may be determined by the resident operating a security app on their mobile device 50 and selecting a button indicating they are home or absent.

[0081] 3-9. Deployment Map The configuration of the layout map 900 is not limited to the example shown in Figure 9; for example, the arrangement of the entrance, shelters, and back entrance may differ from the example shown in Figure 9. Also, instead of one shelter 60 being provided per structure 70, multiple shelters 60 may be provided per structure 70.

[0082] 3-10. Evacuation Map The icons 1201 indicating the location of the suspicious person, 1213 indicating the location of the evacuee's mobile device 50, and 1401 indicating the location of the evacuee's mobile device 50 are not limited to the examples shown in Figure 12 or Figure 14, and should be displayed in a way that distinguishes the location of the suspicious person from the location of the evacuee. For example, the icon 1201 indicating the location of the suspicious person may be shown as a red circle, and the location of the evacuee's mobile device 50 may be shown as a black circle. Also, the number of arrows displayed in the evacuation map 1200 and evacuation map 1400 is not limited to one, but may be two or more. Furthermore, the evacuation map 1200 or 1400 may display the location or name of a person who can protect the evacuee, or it may display information relating to a pre-set hiding place other than the structure 70 (e.g., a public facility).

[0083] In Example 1, the evacuation destination is not limited to the shelter 60 of another structure 70 closest to the current location of the evacuee's mobile terminal 50, but may also be the shelter 60 of a structure 70 where the residents are present.

[0084] The method of indicating evacuation routes is not limited to arrows 1202 and 1402. Evacuation routes may be indicated, for example, along a road, i.e., by a curve. When indicating evacuation routes by a curve, the route may also be shown to avoid encounters with suspicious persons.

[0085] 3-11. Configuration Database The user ID 1004 in the configuration database 1000 is not limited to three per record; for example, there may be four or more.

[0086] 3-12. Processing of the control device 10 and the imaging device 30 Some of the processing performed by the management device 10 may be performed by the imaging device 30. For example, the detection of suspicious persons is not limited to being performed by the management device 10, but may also be performed by the imaging device 30.

[0087] 3-13. Information display on mobile terminal 50 The security system S may provide each resident with a wider variety of information. This information is displayed on each resident's mobile device 50. In one example, the information displayed on each resident's mobile device 50 includes the occupancy status of each shelter. In the example embodiment, since each shelter is equipped with a locking device 40, the security system S can determine who is currently in each shelter from the entry and exit records of the locking device 40 (entry and exit information can be recorded in the database). Alternatively, an occupancy confirmation device may be installed inside the shelter. In this case, for example, a person inside the shelter (hereinafter referred to as "occupant") can operate this occupancy confirmation device to input information indicating that the person is inside. Operations on the occupancy confirmation device include, for example, pressing an occupancy button, sending an email, or inputting information from an app. When sending an email or inputting information from an app, the attributes of the occupant (e.g., number of people, gender, age, and name) may be entered. In another example, the occupancy confirmation device may output a beacon signal in accordance with a standard such as BLE (Bluetooth Low Energy). When the occupant's mobile terminal 50 (e.g., a smartphone) responds to this beacon signal, the occupant's information is input to the occupancy confirmation device. The occupancy confirmation device transmits the occupant's information to the management device 10. The management device 10 transmits the occupant information for each shelter, obtained in this manner, to the mobile terminal 50 of the user corresponding to that shelter. The users corresponding to each shelter are defined in the security system S, and are, for example, the residents of the house where the shelter is installed, or the residents of all houses in the group. This allows the users of the security system S to confirm who is in the shelter.

[0088] Furthermore, when the security system S switches to the global mode, the management device 10 notifies the registered user's mobile terminal 50 that the operating mode has switched to the global mode. The occupant's mobile terminal 50 may periodically (i.e., at regular time intervals) transmit the occupant's information to the occupancy confirmation device while the global mode is maintained.

[0089] In another example, the occupancy status of each residence may be displayed on the mobile terminal 50. In this example, a motion sensor and a beacon signal output device are installed in each residence. When the motion sensor is activated, a beacon signal is output. The mobile terminal 50 of a user registered with the security system S has a corresponding application installed, and upon receiving this beacon signal, the mobile terminal 50 responds with information about the occupant. If there is no response to the beacon signal, the security system S notifies the corresponding user that someone has entered the residence. Alternatively, if there is no response to the beacon signal, the security system S may activate (for example, start) security equipment (for example, a camera).

[0090] 3-14. Persons eligible for entry into the shelter Those eligible to enter the shelter are not limited to residents of the group, i.e., residents of the area. Even non-residents may be eligible to enter the shelter if, for example, they have registered as users in advance with the security system S. Prior user registration may include identity verification processes, such as presenting identification. In other words, when the operating mode of the security system S switches to global mode in a certain area, those who have registered as users in advance are given the authority to unlock the shelter's locking device 40, even if they are not residents of that area. Alternatively, prior user registration may not be required, and the locking device 40 may be unlocked by a key for global mode that can unlock the shelter's locking device 40 when the operating mode switches to global mode. In this case, when the operating mode of the locking device 40 switches to global mode, the unlocking authority is switched so that the key for global mode can unlock the locking device 40.

[0091] 3-15. Imaging device 30 The arrangement and number of imaging devices 30 installed within the area are not limited to those exemplified in the arrangement map 900. For example, imaging devices 30 may be placed at the entrance of each structure 70.

[0092] When the monitoring mode is set to "monitoring," the camera 30 is not limited to not recording video; it may record video for a certain period or a certain amount of video within the recording capacity of the camera 30.

[0093] The imaging device 30 is not limited to continuously performing imaging, recording of captured video, and output of captured video. For example, the imaging device 30 may perform at least one of the following actions only when an abnormality is detected by another sensor (not shown): imaging, recording of captured video, and output of captured video.

[0094] 3-16. Locking device 40 The locking device 40 is not limited to being locked and unlocked by communication using the network 20, but may be locked and unlocked by other methods. For example, the locking device 40 may have a display or keypad, and the locking device 40 may be locked or unlocked when a PIN is entered into the locking device 40 through user operation. Alternatively, for example, the locking device 40 may have an imaging unit, and the locking device 40 may be locked or unlocked when a two-dimensional code such as a QR code (registered trademark) is read into the locking device 40 through user operation.

[0095] The locking device 40 is not limited to being locked from the inside of the door by an evacuee. For example, the locking device 40 may be locked from the outside of the door, or it may be locked by remote operation using a terminal (not shown) that can communicate with the locking device 40, or it may be locked automatically in conjunction with opening and closing operations.

[0096] 3-17. Mobile devices 50 In this embodiment, there is one mobile terminal 50 for the evacuee, but there may be two or more mobile terminals 50 for the evacuee. If there are two or more mobile terminals 50 for the evacuee, the processing shown in Embodiment 1 or Embodiment 2 is performed for each mobile terminal 50.

[0097] The terminal used for unlocking may be different from the mobile terminal 50. For example, a locking device 40 in individual mode can be unlocked only by the mobile terminal 50, while a locking device 40 in global mode can be unlocked by at least one of the mobile terminal 50 and a key for global mode (e.g., a key card). The key for global mode is, for example, as described above, a key that can unlock the shelter's locking device 40 when the operating mode is global mode.

[0098] The mobile device 50 is not limited to a smartphone. The mobile device 50 may be a smartwatch, smart ring, beacon, or dedicated terminal. A beacon is a signal-emitting device that uses, for example, BLE (Bluetooth Low Energy) technology. The security system S can determine, for example, the location of a resident by receiving a signal from a beacon. A dedicated terminal is a terminal designed specifically for the security system S.

[0099] Not all of the functions of the security app exemplified are limited to being implemented through the security app; some of the exemplified functions may be implemented without going through the security app. For example, displaying an evacuation map or communicating with the management device 10 may be performed without going through the security app.

[0100] 3-18. Structure 70 The structure 70 is not limited to a detached house; it is sufficient if the structures 70 are separated from each other. For example, the structure 70 could be a tent used for camping, or a temporary facility erected for construction work, etc. Furthermore, the area is not limited to a residential area consisting of multiple detached houses. For example, the area could be an apartment building (e.g., a condominium), and the structure 70 could be a room in the apartment building (e.g., a room in a condominium). If the structure 70 is a room in a condominium, groups may be formed on each floor, and the security system S may provide security for multiple groups.

[0101] The area is not limited to a geographically limited region, but may also be an area defined by a computer network, for example. For example, even if there are multiple geographically separated regions, if the structures are managed by the same management device 10, they can constitute an "area" as defined in this disclosure. Alternatively, even if a region is geographically a single area, if the computer networks installed in each structure are separated into two, this region can be said to be divided into two areas.

[0102] The structure 70 is not limited to having a shelter 60 specifically for evacuation; for example, a room used daily by the residents may function as the shelter 60 in the overall mode. In that case, the location of the shelter 60 may be flexibly changed by the residents of the structure 70 having that shelter 60.

[0103] It is not limited to the installation of a common security system in each of the structures 70. For example, some structures 70 may have security system A installed, while other structures 70 may have security system B installed, and multiple security systems may be involved within the group. In that case, the management device 10 or another server (not shown) may integrate and manage these multiple security systems.

[0104] 3-19. Others The correspondence between functional elements and hardware elements in the management device 10, the imaging device 30, and the mobile terminal 50 is not limited to those illustrated in the embodiment. For example, some of the functions described as those of the management device 10 in the embodiment may be implemented on another server. Alternatively, some of the functions described as those of the management device 10 in the embodiment may be implemented on other devices on the network. Also, some of the functions described as those of the imaging device 30 in the embodiment may be implemented on another server. Alternatively, some of the functions described as those of the imaging device 30 in the embodiment may be implemented on other devices on the network. Also, some of the functions described as those of the mobile terminal 50 in the embodiment may be implemented on another server. Alternatively, some of the functions described as those of the mobile terminal 50 in the embodiment may be implemented on other devices on the network.

[0105] The operation of the management device 10, the imaging device 30, and the mobile terminal 50 is not limited to the examples described above. The processing procedures of the management device 10, the imaging device 30, and the mobile terminal 50 may be rearranged, and multiple processes may be performed simultaneously, as long as there is no contradiction. In addition, some of the processing procedures of the management device 10, the imaging device 30, and the mobile terminal 50 may be omitted.

[0106] The various programs exemplified in the embodiments may be provided by download via a network such as the Internet, or they may be provided recorded on a computer-readable non-temporary recording medium such as a DVD-ROM (Digital Versatile Disc Read Only Memory). [Explanation of Symbols]
