  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a schematic diagram illustrating an outline of an electronic lock management system 10 according to the present embodiment. The electronic lock management system 10 includes a server device 100, an administrator terminal 200 connected to the server device 100 via a LAN, and an observation camera 300 (300A in the figure) connected to the server device 100 via a wide area network NW. , 300B) and the electronic lock device 400 (400A1 to A3, 400B1 to B3 in the figure) that is also connected to the server device 100, as main components.

  The server device 100 plays a role as an electronic lock management device that manages the locking and unlocking of the electronic lock device 400. The server device 100 manages the electronic lock devices 400 respectively installed in a plurality of management areas via, for example, a wide area network NW that is the Internet. In the example of the figure, the server device 100 manages a plurality of electronic lock devices 400 respectively installed in two management areas, area A and area B. Area A and area B are different management areas. It is desirable to set the management area as an area that is estimated to be damaged in common when a disaster occurs. For simplicity, it may be set in units of municipalities. The management areas may be adjacent to each other or may be separated.

  However, it is desirable that the area X where the server device 100 is installed is a remote area from the management area. If the server device 100 is installed at a remote location with respect to the electronic lock device 400 to be managed, even if a disaster occurs in the management area, the server device 100 can be prevented from being damaged and broken. .

  Here, managing the electronic lock device 400 includes at least that the electronic lock device 400 can be unlocked by an unlock signal transmitted by the server device 100. Further, the electronic lock device 400 can be locked by the lock signal transmitted by the server device 100, and the locked / unlocked state of whether the electronic lock device 400 is locked or unlocked can be grasped. May be.

  In the example illustrated in FIG. 1, in the region A, the server device 100 manages the electronic lock devices 400A1, 400A2, and 400A3 that lock and unlock the management doors A1, A2, and A3 built in the disaster-related building. doing. The building where the control doors A1, A2, A3 are built is, for example, a stockpiling warehouse that stocks water and food, a school gymnasium that serves as an evacuation site, or climbs to a hill where entry is prohibited during normal times It may be an evacuation gate. In addition, in the area A, an observation camera 300A installed at a place where the presence or absence of a disaster in the area A can be observed is installed. The server device 100 can acquire the video captured by the observation camera 300 at regular time intervals via the wide area network NW.

  Also in the area B, similarly to the area A, the server apparatus 100 manages the electronic lock devices 400B1, 400B2, and 400B3 that lock and unlock the management doors B1, B2, and B3 built in the building related to the disaster. ing. In the area B, the observation camera 300B is installed in the same manner as the observation camera 300A.

  In each management area, more electronic lock devices 400 may be installed, or may be installed alone. When a plurality of electronic lock devices 400 are installed, each may be directly connected to the wide area network NW, or a plurality may be connected together by a device RH such as a router and a hub. . A plurality of observation cameras 300 may be installed in the management area, or may not be installed. When a plurality of doors are installed, they may be installed so that the vicinity can be observed for each management door.

  The server device 100 acquires an emergency signal transmitted from the administrative organization. Specifically, the emergency signal may be a warning signal that informs the arrival of a disaster related to a disaster or an evacuation signal that recommends evacuation. For example, an earthquake early warning issued by the Japan Meteorological Agency. Or a tsunami warning, a heavy rain evacuation warning, an eruption evacuation warning, etc. may be sufficient.

  The emergency signal may include information about the area to be alerted. For example, when it is predicted that an earthquake with a seismic intensity of 5 will occur in the area A, the emergency earthquake bulletin includes information on “area A” and “seismic intensity 5”. These emergency signals are signals transmitted from the administrative agencies that have jurisdiction over them, or from the agencies entrusted by the administrative agencies, and the server device 100 automatically sends emergency signals via the Internet, telephone lines, etc. Is configured to get. Even when the emergency signal is transmitted to the area where the warning is issued and the server apparatus 100 is not included in the area, the server apparatus 100 manages at least the electronic lock device 400 installed. It is configured to be able to obtain emergency signals for the region.

  It should be noted here that the emergency signal includes a false alarm. The emergency signal is a warning signal related to life, so it is often sent positively if any danger is predicted. For example, an emergency earthquake warning is sent even though an earthquake does not actually occur. May be. However, the electronic lock device often has a function of protecting the property. For example, if the electronic lock device in the stockpiling warehouse is unlocked even when it is erroneously reported, it may be exposed to looting. Therefore, regarding “unlocking”, the actual occurrence of disaster should be judged more carefully.

  Therefore, in the present embodiment, a configuration is adopted in which unlocking is not performed automatically only by an emergency signal, but is unlocked after being judged by an authorized administrator such as a person in charge of disaster prevention in the local government. The server device 100 is connected to the administrator terminal 200 via a wired LAN, a wireless LAN, or the like. When the server apparatus 100 receives the emergency bulletin, the server apparatus 100 notifies the administrator terminal 200 to that effect and prompts the administrator to input instructions. Based on the video from the observation camera 300, reports from the local area, news, etc., the administrator determines whether a disaster has actually occurred in the target management area and the management door needs to be opened. An instruction is input to the administrator terminal 200.

  The input instruction is transmitted to the server apparatus 100 as an unlocking permission signal. The server device 100 refers to the control file in which the contents of the emergency signal and the unlock permission signal and the information of the electronic lock device 400 to be managed are collected, and the electronic lock device 400 installed in the management door to be opened. Send an unlock signal to. The electronic lock device 400 that has received the unlock signal determines whether or not the received unlock signal matches the authentication data stored in advance, and if it matches, the lock is released. In this way, by interposing the administrator's judgment, it is possible to avoid unlocking the electronic lock device 400 even though no disaster has occurred. Below, the electronic lock management system 10 concerning this embodiment is demonstrated in detail using figures.

  FIG. 2 is a block diagram illustrating the configuration of the server device 100. The server device 100 includes a control unit 102 composed of, for example, a CPU, a network connection unit 104 serving as a network interface, and a storage unit 106 composed of, for example, a hard disk drive. The control unit 102 includes a memory 103 composed of a nonvolatile memory such as a flash memory.

  The control unit 102 comprehensively controls the operation of the components of the server device 100. The memory 103 stores an electronic lock management program for managing the electronic lock by controlling the operation of the server device 100. The control unit 102 calls an electronic lock management program from the memory 103 and executes various processes.

  The network connection unit 104 connects the LAN so that the server apparatus 100 can communicate with the administrator terminal 200. In addition, the network connection unit 104 connects to the Internet so that the server device 100 can communicate with each electronic lock device 400. The control unit 102 and the network connection unit 104 function in a cooperative manner, thereby serving as an emergency signal acquisition unit that acquires an emergency signal and an input reception unit that receives an input from an administrator. In addition, when receiving an emergency signal and transmitting an input promotion signal that prompts the administrator to input to the administrator terminal 200, the server device 100 cooperates with the network connection unit 104 and serves as a promotion unit. .

  The storage unit 106 is a non-volatile storage medium capable of reading and writing data, such as a hard disk. The storage unit 106 stores a control file and a history management file, which will be described later. The control file will be described later. The history management file is a file in which a history such as unlocking time and locking time is recorded for each electronic lock device 400 to be managed. When a plurality of managers are set, the manager's ID or the like may be acquired together, and it may be recorded which manager has instructed locking / unlocking.

  FIG. 3 is a diagram showing a concept of a list structure of control files stored in the storage unit 106. The control file is a file in which the electronic lock device 400 to be managed is registered for each management area as a management key, and a lock / unlock signal for locking and unlocking is associated with each management key. In addition, the control file describes in which disaster the unlock signal is transmitted and under what conditions the lock signal is transmitted, corresponding to each management key.

  For example, in the area A, the electronic lock device 400A1 is registered as the management key A1. The unlocking signal for unlocking the management key A1 is “12bdea03ff”, and it is selected so that the unlocking signal is transmitted when an instruction of earthquake, tsunami, heavy rain, or eruption is received as the disaster type. As a locking condition, it is defined that “no automatic locking”, that is, that the locking signal is not automatically sent from the server device 100. For example, in the region B, the electronic lock device 400B3 is registered as the management key B3. The lock / unlock signal for locking / unlocking the management key B3 is “24ed0925ff”, and is selected so that the unlock signal is transmitted only when an eruption instruction is received as the disaster type. It is defined that the lock signal is automatically sent from the server device 100 two hours after the unlock signal is transmitted, that is, two hours after the unlock signal is transmitted.

  FIG. 4 is a block diagram illustrating the configuration of the administrator terminal 200. The administrator terminal 200 includes a control unit 202 configured by, for example, a CPU, a network connection unit 204 that is a network interface, a display unit 206 configured by, for example, a liquid crystal display, and an operation unit 208 configured by, for example, a keyboard and a mouse. . The control unit 202 includes a memory 203 composed of a nonvolatile memory such as a flash memory.

  The control unit 202 comprehensively controls the operation of the components of the administrator terminal 200. The memory 203 stores an emergency unlocking application program for transmitting an unlocking permission signal including information on the target area and the disaster type. The network connection unit 204 connects the LAN so that the administrator terminal 200 can communicate with the server device 100. The display unit 206 displays a setting screen and a selection screen.

  When the administrator terminal 200 receives the input promotion signal, the administrator terminal 200 launches an emergency unlocking application program on the display screen, for example, blinks a warning window stating “Please input urgently”, and prompts the administrator to input instructions. . At this time, an alarm sound may be output simultaneously. The administrator inputs an instruction by operating the operation unit 208 such as a mouse while looking at the interface screen displayed on the display unit 206.

  A specific interface screen will be described. FIG. 5 is an example of an interface screen displayed on the display unit 206 of the administrator terminal 200. When the emergency unlock application program is launched on the administrator terminal 200, an application window 901 is opened on the display unit 206.

  In the application window 901, a caption “Emergency unlocking” is added, and a selection window 902 for selecting a target area where unlocking is permitted and a radio button 903 for designating a disaster type are arranged. When the selection window 902 is opened as shown in the figure, selectable target areas appear side by side as candidates, and the administrator can select one of them. The target areas appearing as candidates may be all of the management areas managed by the server apparatus 100, or may be narrowed down to areas where the emergency signal overlaps with the warning area. An area adjacent to an area that is a management area and that is alerted by an emergency signal may be a candidate. If the adjacent area is added to the target area, the management door can be opened in response to the evacuees who evacuate from the area where the disaster occurred.

  The radio button 903 is a button for selecting one from the candidates, and is displayed here so that it can be selected from among earthquakes, tsunamis, heavy rains, and eruptions. The candidates displayed here correspond to the disaster types described in the control file. Of course, the types of disaster are not limited to earthquakes, tsunamis, heavy rains, and eruptions, and other disasters may be candidates.

  A video window 910 is superimposed on the application window 901 and displayed. When the administrator selects a target area in the selection window 902, a video from the observation camera 300 installed in the target area is sent via the server device 100 and displayed as a local video in the video window 910. As shown in the figure, a caption indicating which management region the video displayed in the video window 910 is and the acquisition time of the displayed video are displayed near or superimposed on the video window 910. The

  Note that if the observation camera 300 is not installed in the selected target area, or if the observation camera 300 is damaged due to a disaster, the local video is not displayed. When the observation camera 300 is installed but not displayed, the emergency unlocking application program may display so that it can be understood. Further, when a plurality of observation cameras 300 are installed in the target area, the observation cameras 300 may be sequentially switched or displayed simultaneously on a multi-screen.

  The administrator can determine the disaster situation in the target area based on the local video displayed in the video window 910 or the local video not displayed in the video window 910. When the administrator determines that the emergency unlocking of the electronic lock device 400 is necessary in the target area, the administrator clicks the unlock button 904 with the cursor 920. When the emergency unlocking application program detects the click, the emergency unlocking application program causes the control unit 202 to generate an unlocking permission signal including information on the selected target area and the disaster type, and transmits the unlocking signal to the server device 100 via the network connection unit 204. . When the administrator determines that the emergency unlocking of the electronic lock device 400 is unnecessary in the target area, the administrator clicks the cancel button 905 with the cursor 920. When the emergency unlocking application program detects the click, the emergency unlocking application program causes the control unit 202 to generate an unlocking unnecessary signal and transmits it to the server device 100 via the network connection unit 204.

  FIG. 6 is a block diagram illustrating the configuration of the electronic lock device 400. The electronic lock device 400 includes a control unit 402 configured by, for example, a CPU, and a communication unit 404 connected to the wide area network NW. The communication unit 404 includes, for example, an NFC interface based on short-range wireless communication. In normal times, when the visiting user brings the unlocking card close, for example, the control unit 402 reads the authentication signal from the communication unit 404 and unlocks it.

  The electronic lock device 400 includes a drive unit 406 configured by, for example, a solenoid, and a lock unit 408 configured by, for example, a dead bolt that is displaced by driving of the drive unit 406. The storage unit 403 stores authentication data for releasing the lock. When the unlock signal received from the server device 100 or the authentication signal read from the unlock card matches the authentication data stored in the storage unit 403, the control unit 402 drives the drive unit 406, The lock unit 408 is unlocked.

  Since the electronic lock device 400 is a device responsible for locking and unlocking the management door built in the building related to the disaster, it is desirable to provide a backup power supply in addition to the normal household power supply. For example, as a backup power source, a secondary battery or a solar power generator may be provided, or a power supply terminal for connecting an external power source may be provided. For example, a mobile battery that is also used for a smartphone, a portable generator that rotates a user's handle, and the like are connected to the power supply terminal.

  Next, a series of processing flows will be described. FIG. 7 is a diagram illustrating a processing flow of the server apparatus 100. The processing flow shown in the figure is processing executed after the server apparatus 100 is turned on and the electronic lock management program is read from the memory 103. The processing shown here is processing related to the present embodiment, and other processing may be interposed in the middle, or a series of processing flows may be ended when an end instruction is given.

  In step S101, the control unit 102 receives registration of a control file. That is, the administrator needs to give each piece of information of the control file described with reference to FIG. 3 to the server apparatus 100 in order to cause the server apparatus 100 to function as the electronic lock management system 10. Specifically, the administrator launches the emergency unlock application program on the administrator terminal 200, opens a registration screen in the application window 901, and inputs each piece of information. For example, when registering the management key A1, the management key A1 belongs to the area A where the management key A1 is installed, and the code of the unlock signal is input. Also, for example, if the management key A1 is provided at the management door of the evacuation center where the refugee stays, the disaster can be used in any disaster and in the long term Select and input all items as types and “no automatic locking” as locking conditions. When the administrator finishes inputting all the management keys, the administrator terminal 200 transmits the registration information to the server device 100. In step S 101, registration is received by receiving this registration information, and a control file is generated and stored in the storage unit 106. Control file registration may be additionally received later in addition to the initial registration.

  When registration of the control file is completed, the emergency signal reception standby state is entered. In step S102, the control unit 102 waits for reception of an emergency signal. When the emergency signal is received in step S102, the process proceeds to step S103.

  In step S <b> 103, the control unit 102 attempts to call the administrator by transmitting an input promotion signal that prompts the administrator to input to the administrator terminal 200. Then, the process proceeds to step S104, and waits for a predetermined time whether an unlocking permission signal or an unlocking unnecessary signal is sent from the administrator terminal 200. If there is no response, the process returns to step S102 to prepare for reception of the next emergency signal. Even when an unlocking unnecessary signal is sent, the process returns to step S102. On the other hand, if an unlocking permission signal is sent, the process proceeds to step S105.

  In step S105, the control unit 102 reads the target area information and the disaster type information included in the unlocking permission signal, refers to the control file, and determines a management key that satisfies the condition as an unlocking target key. Specifically, for example, when “region A” is designated as the target region information and “earthquake” is designated as the disaster type information, according to the example of FIG. 3, the management keys A1 and A3 Satisfies the condition, and the control unit 102 determines these as unlocking target keys.

  Next, in step S106, the control unit 102 transmits an unlock signal to the unlock target key. In the above example, “12bdea03ff” is sequentially transmitted to the management key A1, and “14edec25ff” is sequentially transmitted to A3. If unlocking is successful for each unlocking key, the unlocking key sends an unlocking completion signal back to the server apparatus 100. When receiving the unlocking completion signal from each unlocking target key, the control unit 102 records the management key number of the unlocking target key and the unlocking time corresponding to it in the management history file in step S107. .

  Proceeding to step S108, the control unit 102 refers to the control file and determines whether or not a locking instruction is specified in the locking condition of the unlocking target key. If the locking instruction is not specified, the process proceeds to step S111. In the above example, since the management key A1 is “no automatic locking”, it is determined that the locking instruction is not specified. When the locking instruction is designated, the process proceeds to step S109.

  In step S109, the control unit 102 waits until the locking instruction matches the locking condition. In the above example, the management key A3 is designated as “locked after 2 hours”, and the control unit 102 waits until 2 hours have elapsed from the transmission of the unlock signal.

  When the locking instruction matches the locking condition, the process proceeds to step S110, and the control unit 102 transmits a locking signal to the unlocking target key for which the locking condition is set. If the unlocking is successful for each unlocking target key, the unlocking target key returns a locking completion signal to the server apparatus 100. When receiving the lock completion signal from each unlocking target key, the control unit 102 records the management key number of the unlocking target key and the locking time corresponding thereto in the management history file in step S111. Even if the key to be unlocked for which no locking instruction is specified, if the key is unlocked by local operation after unlocking, a lock completion signal is sent back to the server device 100, and the control unit 102 stores the management history file. In addition, the management key number of the unlocking target key and the locking time are recorded corresponding to the management key number.

  After completing the locking history process in step S111, the control unit 102 returns to step S102 again and prepares for reception of the next emergency signal.

  In the embodiment described above, an example in which the administrator terminal 200 starts an application program in response to a promotion signal from the server device 100 has been described. However, the administrator may start up an application program by himself / herself and send an unlock permission signal to the server apparatus 100.

  In the embodiment described above, the key to be unlocked is determined according to the description of the control file. However, the administrator may directly specify the key by the application program. Further, in the embodiment described above, an example in which the administrator selects the target area has been described. However, the area where the warning included in the emergency signal may be directly set as the target area.

  In the embodiment described above, an example in which management related to locking is performed on the server device 100 side is shown. However, the locking condition is added to the unlocking signal and transmitted to the key to be unlocked, and the management related to locking is released. It may be performed on the lock target key side.

  In the embodiment described above, the video of the observation camera 300 is used so that the status of the target area can be checked. However, the status check is not limited to video usage, for example, information written to a social network is used. May be.

  In the embodiment described above, the example in which the electronic lock management system is configured by one server has been described. However, the server may be composed of a plurality of servers instead of one, and each server may perform the processing while sharing the role. For example, a server for input by an administrator and a server for transmitting an unlock signal can be separated.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above-described embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.

  The order of execution of each process such as operations, procedures, steps, and stages in the apparatus, system, program, and method shown in the claims, the description, and the drawings is particularly “before” or “prior to”. It should be noted that the output can be realized in any order unless the output of the previous process is used in the subsequent process. Regarding the operation flow in the claims, the description, and the drawings, even if it is described using “first”, “next”, etc. for convenience, it means that it is essential to carry out in this order.
