Therefore, an object of the present invention is to provide control that locks during normal times and enables unlocking in an emergency in the storage of emergency supplies.

Means for Solving the Problems

[0005] The present invention provides a storage device for storing stockpiled goods. This storage device comprises a storage cabinet, an electronic lock for locking and unlocking the storage cabinet, a power supply circuit supplied with power from an external power source, a communication unit for communicating with an external device, and a control unit. The control unit controls the locking and unlocking of the electronic lock based on one or more of the following: information received through communication via the communication unit, the power supply status from the external power source supplied to the power supply circuit, and the communication status of the communication unit. [Effects of the Invention]

[0006] According to the present invention, a control system is realized for storing stockpiled goods that locks them during normal times and allows them to be unlocked in emergencies. Other problems, configurations, and effects not mentioned above will be clarified by the following description of embodiments for carrying out the invention. [Brief explanation of the drawing]

[0007] [Figure 1] This diagram shows an example of the overall system configuration. [Figure 2] This is a diagram showing an example of the configuration of a storage device. [Modes for carrying out the invention]

[0008] Embodiments of the present invention will be described below with reference to the drawings. The embodiments are illustrative examples for explaining the present invention, and have been omitted and simplified as appropriate for clarity of explanation. The present invention can also be implemented in various other forms. Unless otherwise specified, each component may be singular or plural.

[0009] First, an example of a system equipped with a storage device 1000 will be described with reference to Figure 1. As shown in Figure 1, this system comprises a storage device 1000, a management server 1001, and information processing terminals (1002a, 1002b), all of which are connected via a network.

[0010] The storage device 1000 stores emergency supplies and is placed in appropriate evacuation centers during disasters (for example, schools or hospitals equipped with emergency supply warehouses). The storage device 1000 stores various items as emergency supplies, such as batteries. The management server 1001 manages various information within the system. The management server 1001 manages information related to emergency supplies, such as expiration date information, inventory information, and battery capacity information. Businesses and management organizations can then utilize the information managed by the management server 1001 in their operations.

[0011] The information processing terminal 1002a is used by a business operator, such as a supplier of disaster relief supplies. The business operator can use the information processing terminal 1002a to obtain information from the management server 1001 and take appropriate action.

[0012] For example, the operator may replenish the stockpiled batteries before their expiration date and collect and recycle the batteries that are nearing their expiration date. Here, the operator may control the operation of the storage device 1000 using the information processing terminal 1002a. The operator can also use the information processing terminal 1002a to update the information on the management server 1001 with the latest information after the work is completed. Alternatively, the same process may be performed using a communication terminal 1003 held by the on-site worker and connected to the network. The management server 1001 may also manage information related to work, such as the initial settings when the storage device 1000 was installed, settings during maintenance, and information on replenishment / collection.

[0013] The information processing terminal 1002b is used by the management organization. Here, the management organization is, for example, a local government, a medical institution management organization, or an organization that manages schools, hospitals, etc. that serve as evacuation centers. The management organization uses the information processing terminal 1002b to take appropriate action regarding the storage device 1000.

[0014] The management organization can, for example, use the information processing terminal 1002b to change the settings of the storage device 1000 in an emergency such as the occurrence of a disaster. Furthermore, the management organization can, for example, use the information processing terminal 1002b to instruct the charging control of the storage device.

[0015] Each information processing terminal (1002a, 1002b) may access the storage device 1000 via the network and the management server 1001. Alternatively, they may access the storage device 1000 via the network without going through the management server 1001. Furthermore, a communication terminal 1003 held by an employee of the business operator may communicate directly with the storage device 1000 without going through the network.

[0016] Next, an example of the configuration of the storage device will be described with reference to Figure 2. As shown in Figure 2, the storage device 1000 comprises a plurality of storage compartments (1 to 3) capable of storing items such as stockpiled goods, and a management circuit unit 11. The storage device 1000 can, as an example, have a housing structure in which each of the opening and closing doors of each storage compartment is located on the front side.

[0017] Storage cabinet 1 stores the manual keys to the other storage cabinets; in this example, it stores manual key 2 for storage cabinet 2 and manual key 3 for storage cabinet 3. Here, the opening and closing door of storage cabinet 1 is locked / unlocked by an electronic lock 1 electrically connected to the control circuit unit 11.

[0018] Storage room 2 stores disaster relief supplies (in the example shown in Figure 2, electrical appliances, flashlights, radios, and power distributors). The door of storage room 2 is locked / unlocked by an electronic lock 2 electrically connected to the control circuit unit 11. In addition to the electronic lock 2, the door of storage room 2 can also be locked / unlocked using a manual lock 2 stored in storage room 1.

[0019] The storage vault 3 stores primary batteries and secondary batteries as reserve batteries, and houses a voltage measuring device, terminal insulation tape, a recycling box 101 for packaging, and a recycling box 102 for batteries. Here, the opening / closing door of the storage vault 3 is locked / unlocked by an electronic lock 3 electrically connected to the management circuit unit 11. Also, separately from the case of the electronic lock 3, it is also possible to lock / unlock the opening / closing door of the storage vault 3 by using a manual lock 3 stored in the storage vault 1.

[0020] The secondary batteries stored in the storage vault 3 are arranged in a secondary battery arrangement unit 103 electrically connected to the management circuit unit 11, and the secondary batteries arranged in the secondary battery arrangement unit 103 can be supplied with power (charged) from the management circuit unit 11.

[0021] The voltage measuring device, terminal insulation tape, recycling box 101 for packaging, and recycling box 102 for batteries are used by operators for replenishing / collecting reserve batteries. The reserve batteries (primary batteries) are stored with terminal insulation tape attached to the electrode terminals by the operator. The operator measures the voltage of the reserve batteries (primary batteries) with the voltage measuring device, and puts the reserve batteries (primary batteries) that do not reach the specified threshold value into the recycling box 102 for batteries as recycling targets. Also, the operator puts the packaging of the reserve batteries into the recycling box 101 for packaging as a recycling target. By pre-storing the recycling boxes (101, 102) in the storage vault 3 in this way, it is possible to easily separate and collect the batteries and packaging to be recycled during work.

[0022] The management circuit unit 11 is connected to the electronic locks of each storage vault and performs electrical control. The management circuit unit 11 includes a control unit 12, a communication unit 13, a display unit 14, a voice input unit 15, a voice output unit 16, an operation input unit 17, a power supply circuit 18, and a power supply unit 19. Also, the management circuit unit 11 includes a locking / unlocking management unit 21 and a position information acquisition unit 22. Also, the management circuit unit 11 includes a storage unit (not shown) for storing data used for data processing.

[0023] The control unit 12 serves as the entity that performs predetermined processes and is constituted by an appropriate processor. The control unit 12 is constituted, for example, by using a CPU (Central Processing Unit), but may also be constituted by using other semiconductor devices. The communication unit 13 is used for communication. In the present embodiment, the communication unit 13 is constituted by using a wireless communication interface. The display unit 14 is used for presenting appropriate information and is constituted by using an appropriate display. As an example, the display unit 14 may be provided on the outer side surface of the storage device 1000. The voice input unit 15 is used for operations by voice input and is constituted, for example, by using a microphone. The voice output unit 16 is used for voice output and is constituted, for example, by using a speaker. The operation input unit 17 is configured to be used for appropriate input operations such as buttons and touch panels. The power supply circuit 18 is a circuit used for power supply, and power is supplied to the management circuit unit 11 from the outside of the storage device 1000 via the power supply circuit 18. Note that, as an example, the external power is supplied via a power outlet. The power feeding unit 19 is configured as a circuit used for power feeding.

[0024] The locking / unlocking management unit 21 is constituted as an electric circuit connected to each electronic lock and is used for locking / unlocking each electronic lock. The position information acquisition unit 22 acquires the position information of the storage device 1000 and can be constituted, for example, by using a GPS receiver.

[0025] The storage unit appropriately stores data used for data processing and is constituted by using a main storage device and an auxiliary storage device. The main storage device is a device that temporarily stores data when the control unit 12 performs data processing and is constituted, for example, by using a RAM (Random Access Memory). The auxiliary storage device is a device that stores data such as programs for realizing the operation of the management circuit unit 11 and is constituted, for example, by using an HDD (Hard Disk Drive).

[0026] The storage device 1000 is equipped with a secondary battery 201 for the control unit. The secondary battery 201 for the control unit is used as an auxiliary power source for the control circuit unit 11, and for example, supplies power to the control circuit unit 11 when there is no power supply from the power supply circuit 18.

[0027] The storage device 1000 includes a lighting unit 301. The lighting unit 301 may be installed on the upper side of the storage device, for example, to illuminate the opening and closing doors of the storage cabinet. This makes it possible to determine the position of the opening and closing doors and to easily take out and put in equipment, even in dark environments such as at night. Lighting may also be installed in other locations, such as inside the storage cabinet.

[0028] Furthermore, the storage device 1000 may be provided with wheels 401 on its lower part to facilitate movement, taking into consideration installation work and rearrangement in evacuation shelters.

[0029] Under normal circumstances, external power is supplied from the power supply circuit 18, and the storage device 1000 stores items in the storage compartment with each electronic lock locked. Next, various control examples that enable unlocking in emergencies will be described in detail.

[0030] <Example of control when no external power input is available> The storage device 1000 (specifically, the control unit 12) switches power to the secondary battery 201 for the management unit when the power supply from the power circuit 18 is lost due to a disaster or the like. The control unit 12 then makes a determination based on the state and usage time of the secondary battery 201 for the management unit, and controls the unlocking of the electronic locks based on the determination result. As a specific example, the control unit 12 may determine whether the battery level of the secondary battery 201 for the management unit is at a predetermined level, and unlock all or some of the electronic locks when the predetermined level is reached. Alternatively, the control unit 12 may determine whether a predetermined time has elapsed since the power switch was made, based on the perspective of a timeout, and unlock all or some of the electronic locks when the predetermined time has elapsed. Some of the electronic locks include, for example, the electronic locks of storage cabinets that are pre-set to be unlocked in this control. Some of the electronic locks may include, for example, the electronic locks of storage cabinets that store manual keys.

[0031] Furthermore, the control unit 12 maintains communication even after the power supply is switched. It then performs processing to transmit appropriate information, such as information regarding the switch to the secondary battery 201 for the management unit (i.e., the power supply being used) and information regarding the locking and unlocking status of the electronic lock, to the management server 1001 and the management organization's information processing terminal (1002b), etc.

[0032] <Examples of control during emergencies (disasters, etc.)> The storage device 1000 (specifically, the control unit 12) performs the following controls in emergencies such as the occurrence of a disaster.

[0033] As a first example, if the management organization changes the settings of the storage device 1000 and sets the storage device 1000 to emergency mode, the control unit 12 performs control corresponding to the emergency mode. The emergency mode is a mode in which the conditions for unlocking are relaxed compared to the normal mode. In emergency mode, for example, someone other than the person managing the storage device 1000 can unlock the electronic lock with just an input operation without communication. In contrast, in normal mode, the electronic lock cannot be unlocked by input operation by anyone other than the person managing the storage device 1000.

[0034] In emergency mode, the lock can be opened by appropriate input operations. The storage device 1000 may, for example, be provided with an emergency button. That is, the operation input unit 17 may include an emergency button. When this emergency button is pressed, the control unit 12 may open the electronic lock. Alternatively, for example, the microphone of the voice input unit 15 may be used, and the control unit 12 may open the electronic lock based on the result of voice recognition.

[0035] As a second example, if the system is set to emergency mode as described above, the control unit 12 performs control corresponding to the emergency mode. When an input operation is performed, the control unit 12 unlocks only the electronic lock of the storage cabinet where the manual key is stored. Therefore, the manual keys for the other storage cabinets can be retrieved, and they can be unlocked using the manual keys. As described above, unlocking is possible by using an appropriate input operation, such as pressing the emergency button.

[0036] As a third example, if the system is set to emergency mode as described above, the control unit 12 performs control corresponding to the emergency mode. In this example, when an input operation such as pressing the emergency button is performed, the control unit 12 first communicates with the management organization's information processing terminal 1002b. Subsequently, if permission to unlock is output from the management organization's information processing terminal 1002b, the control unit 12 unlocks the electronic lock. In other words, the control unit performs unlocking via communication.

[0037] For example, the situation may be confirmed through conversation between a member of the management organization and the input operator using the voice input unit 15 and the voice output unit 16, etc. Alternatively, the conversation between the member of the management organization and the input operator may be omitted, and permission to unlock may be output.

[0038] Furthermore, the control unit 12 may, as described above, unlock all electronic locks, or it may unlock only the electronic locks of specific storage cabinets. The control unit 12 may also unlock only the electronic locks of storage cabinets that store pre-set manual keys.

[0039] As a fourth example, the control unit 12 may determine whether it is an emergency based on the communication status and perform processing based on that determination. If the control unit 12 determines that communication is impossible, it may switch to emergency mode and relax the conditions for unlocking, without the management organization's judgment. Then, in response to an input operation similar to the above, such as using the emergency button, the control unit 12 may unlock the electronic lock.

[0040] The storage device 1000 may be equipped with a camera, and in the examples 1 to 4 above, it may monitor the input operator. The storage device 1000 may store the image data captured by the camera in its storage unit, and if communication is possible, it may transmit the image data to the management server 1001 or the management organization's information processing terminal 1002b. The storage device 1000 may also store the input operations as operation logs in its storage unit. Similarly, if communication is possible, the storage device 1000 may transmit the operation logs to the management server 1001 or the management organization's information processing terminal 1002b.

[0041] <Example of control under communication conditions> Furthermore, the storage device 1000 (specifically, the control unit 12) may perform the following controls from the viewpoint of communication status.

[0042] As a first example, the control unit 12 may determine whether communication is possible, and if it determines that communication is not possible, it may unlock all electronic locks. As a second example, if the control unit 12 determines that communication is impossible and that there is no power supply from an external power source via the power supply circuit 18, it may unlock all electronic locks. As a third example, the control unit 12 may determine whether communication is possible, and if it determines that communication is not possible, it may unlock only some of the electronic locks on the storage cabinets (for example, the electronic locks on the storage cabinets that have been set in advance). As a fourth example, if the control unit 12 determines that communication is impossible and that there is no power supply from an external power source via the power supply circuit 18, it may unlock only some of the electronic locks on the storage cabinets (for example, the electronic locks on the storage cabinets that have been set in advance).

[0043] Various control examples have been described, but the following control methods may also be used. Furthermore, the following modifications may be made.

[0044] The storage device 1000 may be equipped with a sensor to detect the opening and closing of the storage cabinet door. The storage device 1000 may also transmit information regarding the opening and closing of the storage cabinet door to the management server 1001 or information processing terminals (1002a, 1002b). In an emergency, this information regarding the opening and closing of the door may be stored in a memory unit and, if communication is possible, transmitted to the management server 1001 or information processing terminals (1002a, 1002b).

[0045] During operations such as moving or setting up the storage device 1000, the power supply from the external power source via the power circuit 18 may be lost, potentially causing the electronic lock to unlock due to the control described above. Therefore, the storage device 1000 (specifically, the control unit 12) may perform control to switch to work mode. Here, work mode is a mode in which the unlocking control described above is not performed. In other words, work mode is a mode in which the electronic lock is kept locked. After the work is completed, the system may switch from work mode to normal mode and perform the unlocking control described above. In this way, by switching the work mode on and off, it is possible to prevent the electronic lock from unlocking during work and to perform appropriate control during normal operation.

[0046] The change in work mode may be performed, for example, based on output from the operator's information processing terminal 1002a. It may also be performed based on output from the worker's communication terminal 1003. It may also be performed based on input from the operation input unit 17 of the storage device 1000. Furthermore, authentication such as password authentication may be required during the work mode change process, and the process may be performed based on the authentication result.

[0047] When supplying power to a stored secondary battery via the power supply unit 19, the control unit 12 may supply power to the secondary battery while power is being supplied from an external power source via the power supply circuit 18. On the other hand, the control unit 12 may control the system so as not to supply power to the secondary battery when power is not being supplied from an external power source via the power supply circuit 18. Furthermore, in an emergency, the control unit 12 may control the system to supply power from the stored secondary battery to the management circuit unit 11 via the power supply unit 19. Here, the control unit 12 may determine an emergency to occur, for example, when the remaining charge of the management unit secondary battery 201 falls below a predetermined level, or when a predetermined time has elapsed since the start of use of the management unit secondary battery 201.

[0048] In the unlocking permission control using the management organization's information processing terminal 1002b, information specifying the electronic lock to be unlocked is output from the information processing terminal 1002b, and the control unit 12 may unlock the specified electronic lock.

[0049] The display unit 14 may, for example, display information using electronic paper. In this case, the power consumption during display is reduced, so the last display state can be maintained even if the power supply from the secondary battery 201 for the control unit is lost.

[0050] A storage facility for stockpiled batteries (primary batteries) may be provided with a primary battery storage section 104 that has separate refill and outlet ports for primary batteries, allowing primary batteries nearing their expiration date to be supplied first. For example, the primary battery storage section 104 can be configured as a box-shaped housing with a refill port at the top front and an outlet at the bottom front. In addition, stockpiled batteries (secondary batteries) may be provided with an information storage unit (for example, an RFID tag). The information storage unit may store information related to battery life, such as the number of charge cycles and the date and time of charge. In other words, the information storage unit may store information related to the charging history. By referring to the information stored in the information storage unit, maintenance and battery replacement work can be made easier.

[0051] If the communication unit 13 receives information regarding the predicted occurrence of a disaster (for example, weather information such as typhoons or heavy rain) in advance, the control unit 12 may perform control to increase the charge level of the reserve battery (secondary battery) from the time before the predicted date and time of the disaster (for example, 1 to 3 days before) compared to normal times. As an example, the control unit 12 may charge the battery to a charge level of 70% under normal circumstances, and when disaster prediction information is received, it may perform control to charge the battery to a charge level of 80 to 90%.

[0052] Furthermore, the information processing terminal 1002b of the management organization may send a command to the storage device 1000 installed in the area where a disaster is expected to increase the charge level of the secondary battery. The control unit 12 may then perform charging based on the command from the information processing terminal 1002b to increase the charge level of the secondary battery.

[0053] In the event of a disaster, when the system enters emergency mode and power is supplied from an external power source via the power supply circuit 18, the control unit 12 may perform control to increase the charge level of the stored battery (secondary battery). The control unit 12 may also perform control to switch from the normal charging mode to a rapid charging mode, such as by increasing the charging current.

[0054] Furthermore, storage devices 1000 installed in areas adjacent to areas where a disaster is predicted (or where a disaster has occurred) may be controlled in the same way as storage devices 1000 installed in the areas where a disaster is predicted (or where a disaster has occurred), such as changing the charge level and switching to rapid charging mode. Storage devices 1000 from adjacent areas may also be delivered to the disaster-stricken area. This allows the disaster-stricken area to use secondary batteries with high charge levels stored in storage devices 1000 delivered from adjacent areas.

[0055] Furthermore, storage devices 1000 in neighboring areas may perform control to change their charging based on commands from the management organization's information processing terminal 1002b. Also, storage device 1000 may acquire information on the charging status of other storage devices 1000 and location information of storage devices 1000 installed in other areas via the network and communication unit 13, determine whether the storage device 1000 whose charging has been changed is located in a neighboring area, and perform control to change its charging. Here, as an example, whether an area is considered a neighboring area may be determined by the distance based on the location information of each storage device 1000, or if the distance between storage devices 1000 based on location information is less than or equal to a predetermined distance, it may be determined to be a neighboring area.

[0056] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments described above, and various design modifications can be made without departing from the spirit of the invention as described in the claims. For example, the embodiments described above are described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described. Furthermore, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. Moreover, it is possible to add, delete, or replace parts of the configuration of each embodiment with other configurations.

[0057] The operator may replace the storage device 1000 itself to replace the stockpiled supplies. In addition, the operator's workers may replenish the disaster relief supplies stored in the storage compartment of the storage device 1000, and the operators' workers may also collect the supplies according to their expiration dates.

[0058] Examples of primary batteries to be stockpiled include dry cell batteries, coin cell batteries, and button cell batteries. Examples of secondary batteries to be stockpiled include solid-state batteries, rechargeable dry cell batteries, and portable batteries with terminals.

[0059] The storage device 1000 may be installed by the operator's workers. Alternatively, it may be installed by shelter staff or others after the delivery by the delivery company. [Explanation of Symbols]
