The door motion detection unit 104 only needs to be able to detect the opening / closing motion of the door 11, regardless of the details of the detection method.

The locking / unlocking unit 105 locks / unlocks the door 11. The locking / unlocking portion 105 is realized by, for example, a solenoid coil feeding portion 21, a solenoid coil 22, a pin receiving keyhole 23, a movable pin 24, and a pin receiving hole 25. The details of the locking / unlocking unit 105 are not limited as long as the door 11 can be locked / unlocked.

The storage unit 110 stores information for operating the storage device 100. The storage unit 110 is realized by, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory).

The storage unit 110, for example, has information for identifying the terminal device 200 having the unlocking authority of the door 11 (hereinafter referred to as registered terminal identification information) and information for identifying the user having the unlocking authority for the door 11 (hereinafter referred to as the registered terminal identification information). (Called registered user identification information) is stored. In the following description, the terminal device 200 corresponding to the registered terminal identification information is referred to as a registered terminal device 200.

The details of the registered user identification information do not matter as long as it is information that identifies a user who has the authority to unlock the door 11. The information that identifies the user may be, for example, a password set by the user. Alternatively, the information that identifies the user may be, for example, biological information (fingerprint information, iris information, vein information, face image information, etc.). In the following description, the user corresponding to the registered user identification information is referred to as a registered user.

The control unit 120 controls the entire storage device 100. The control unit 120 is realized by a processor such as a CPU (Central Processing Unit). For example, the processor reads and executes the program stored in the control unit 120, so that the processor operates as the control unit 120.

The control unit 120 includes, for example, an authentication control unit 121, a locking / unlocking control unit 122, and a notification unit 123.

The authentication control unit 121 authenticates at least one of the terminal device 200 and the operator. Specifically, when the input unit 102 receives the information for identifying the user to be authenticated, the authentication control unit 121 authenticates the user to be authenticated based on the registered user identification information. Then, when the authentication control unit 121 authenticates the operator based on the registered user identification information, the registered terminal identification information may be acquired or updated based on the operation of the authenticated operator with respect to the input unit 102. Then, the authentication control unit 121 may store the acquired registered terminal identification information in the storage unit 110. As a result, the authentication control unit 121 can limit the acquisition and update of the registered terminal identification information to the registered users.

Further, when the authentication control unit 121 acquires the terminal identification information of the terminal device 200 to be authenticated, it authenticates the acquired terminal device 200 to be authenticated based on the registered terminal identification information.

The locking / unlocking control unit 122 controls the locking / unlocking of the door 11. Specifically, the lock / unlock control unit 122 locks / unlocks the door 11 based on the strength of the signal received from the terminal device 200 by the communication unit 101 by direct communication.

More specifically, the lock / unlock control unit 122 locks the door 11 when the strength of the signal received from the terminal device 200 by the communication unit 101 is less than a predetermined threshold value. On the other hand, the locking / unlocking control unit 122 unlocks the door 11 when the strength of the signal received from the terminal device 200 by the communication unit 101 is equal to or higher than a predetermined threshold value.

When the communication unit 101 receives the signal from the registered terminal device 200 without going through the communication network (that is, by direct communication) and the strength of the signal is less than a predetermined threshold value, the locking / unlocking control unit 122 Locks the door 11. On the other hand, when the communication unit 101 receives the signal from the registered terminal device 200 without going through the communication network (that is, by direct communication) and the strength of the signal is equal to or higher than a predetermined threshold value, the lock / unlock is performed. The control unit 122 unlocks the door 11. Alternatively, when the strength of the signal received by the communication unit 101 from the registered terminal device 200 by direct communication is equal to or higher than a predetermined threshold value and is within a predetermined range, the lock / unlock control unit 122 unlocks the door 11. You may lock it.

For example, assume that the storage device 100 is a refrigerator installed in the user's home of the terminal device 200. Then, it is assumed that the user of the terminal device 200 is at home. Further, at a position where the storage device 100 can directly communicate with the storage device 100 (that is, the storage device 100 can receive a signal from the terminal device 200 without going through the communication network) and the strength of the signal is equal to or higher than a predetermined threshold value. Suppose there are 200. In that case, the locking / unlocking control unit 122 unlocks the door 11. As a result, the user or the like of the terminal device 200 can take out the article (for example, food) stored in the storage device 100.

On the other hand, it is assumed that the user of the terminal device 200 carries the terminal device 200 and goes out. Then, it is assumed that the terminal device 200 exists at a position where the strength of the signal from the terminal device 200 is less than a predetermined threshold value (for example, direct communication between the terminal device 200 and the storage device 100 is not possible). In that case, the locking / unlocking control unit 122 locks the door 11. As a result, when the user of the terminal device 200 goes out with the terminal device 200, for example, a domestic servant who is at home takes out an article (for example, food) stored in the storage device 100. I can't.

The storage device 100 may include a temperature sensor (not shown) that measures the temperature inside the box body 10. Then, the lock / unlock control unit 122 may unlock the door 11 when the temperature inside the box body 10 deviates from a predetermined set temperature range. This is done by unlocking the door 11 in an emergency when the temperature inside the storage device 100 cannot be controlled due to a power failure or failure when the storage device 100 has a heat retention function such as a refrigerator. It is possible to quickly move the stored items within 100.

Further, if the door 11 opens and closes after the lock / unlock control unit 122 unlocks the door 11, the lock / unlock control unit 122 may lock the door 11.

Further, the lock / unlock control unit 122 may lock / unlock the door 11 based on the operation of the registered user with respect to the input unit 102. For example, when the input unit 102 receives the registered user identification information, the lock / unlock control unit 122 may unlock the door 11. That is, when the operator is a registered user, the locking / unlocking control unit 122 may unlock the door 11. The registered user identification information that locks and unlocks the door 11 may be different from the above-mentioned registered user identification information that enables acquisition and update of the registered terminal identification information. In this case, it is preferable that the registered user identification information that enables acquisition and update of the registered terminal identification information has higher security strength than the registered user identification information that locks and unlocks the door 11. Further, when the input unit 102 receives the registered user identification information that enables the acquisition and update of the registered terminal identification information, the lock / unlock control unit 122 may unlock the door 11.

Further, for example, when the door 11 is closed after the lock / unlock control unit 122 unlocks the door 11 by receiving the registered user identification information by the input unit 102, the lock / unlock control unit 122 locks the door 11. May be good. As a result, the registered user can unlock the door 11 and the registered user can lock the door 11 without performing the locking operation.

Note that the lock / unlock control unit 122 may lock the door 11 when the lock / unlock control unit 122 is not energized. Further, the storage device 100 includes a rechargeable battery (not shown), and when the storage device 100 cannot supply power from the power source, the locking / unlocking control unit 122 supplies power from the rechargeable battery to lock the door 11. You may. As a result, for example, when the outlet of the storage device 100 is unplugged, the door 11 is locked, so that it is possible to prevent the articles stored inside the box body 10 from being stolen.

The notification unit 123 notifies the terminal device 200 of the status of the storage device 100. For example, the notification unit 123 may notify the terminal device 200 whether or not the door 11 is locked (or unlocked).

Next, the functional configuration of the terminal device 200 will be described.

FIG. 5 is a block diagram showing an example of the functional configuration of the terminal device 200. The terminal device 200 includes, for example, a storage unit 201, a communication unit 202, an input unit 203, a control unit 204, and a notification unit 205.

The storage unit 201 stores information for operating the terminal device 200. The storage unit 201 stores, for example, terminal identification information. The storage unit 201 is realized by, for example, a ROM or a RAM.

The communication unit 202 wirelessly communicates with the storage device 100. For example, the communication unit 202 may directly communicate with the terminal device 200 by using Bluetooth, BLE, or the like. The communication unit 202 is realized by, for example, a NIC or the like.

The input unit 203 receives user input and is realized by a keyboard, a touch panel, buttons, or the like.

The control unit 204 controls the entire terminal 200. The control unit 204 is realized by a processor such as a CPU. For example, the processor reads and executes the program stored in the storage unit 201 to operate as the control unit 204.

The notification unit 205 notifies the user of the information. For example, when the communication unit 202 receives information about the state of the storage device 100 (for example, whether or not the door 11 is locked (or unlocked)) from the storage device 100, the notification unit 205 receives the storage device 100. Notify the user of information about the status. The notification unit 205 only needs to be able to notify the user of the information, and the details of the notification method do not matter. For example, the notification unit 205 may notify the user of information by using characters, images, sounds, lights, vibrations, and the like.

FIG. 6 is a flowchart showing an example of the operation of the storage device 100.

In step S11, the locking / unlocking control unit 122 determines whether or not the strength of the signal received from the registered terminal device 200 by direct communication is equal to or higher than a predetermined threshold value.

When the strength of the signal received from the registered terminal device 200 by direct communication is equal to or higher than a predetermined threshold value (step S11: Yes), the lock / unlock control unit 122 unlocks the door 11 (step S12). .. Then, the control returns to step S11 and continues the process.

On the other hand, when the strength of the signal received from the terminal device 200 by direct communication is less than a predetermined threshold value (step S11: No), the locking / unlocking control unit 122 determines whether or not the door 11 is closed (step S11: No). Step S13).

When the door 11 is closed (step S13: Yes), the locking / unlocking control unit 122 locks the door 11 (step S14). Then, the control returns to step S11 and continues the process. On the other hand, when the door 11 is not closed (step S13: No), the locking / unlocking control unit 122 waits until the door 11 is closed. For example, it is assumed that the door 11 is opened when the strength of the signal received by the communication unit 101 from the registered terminal device 200 by direct communication is smaller than a predetermined threshold value. In that case, when the door 11 is closed, the lock / unlock control unit 122 locks the door 11.

Further, for example, after the lock / unlock control unit 122 unlocks the door 11 and the operator of the storage device 100 opens the door 11, the communication unit 101 receives a signal directly from the registered terminal device 200 by communication. It is assumed that the intensity becomes smaller than a predetermined threshold value. In that case, the door 11 is locked after the operator of the storage device 100 closes the door. As a result, when the strength of the signal received by the communication unit 101 from the registered terminal device 200 by direct communication is less than a predetermined threshold value, when the operator of the storage device 100 closes the door 11, the door 11 Is automatically locked. Therefore, when the strength of the signal received by the communication unit 101 from the registered terminal device 200 by direct communication is smaller than a predetermined threshold value, the operator of the storage device 100 needs to perform an operation of locking the door 11. There is no. The above flow is an example, and the present embodiment is not limited to this. For example, when the strength of the signal received from the terminal device 200 by direct communication is smaller than a predetermined threshold value (step S11: No), the lock / unlock control unit 122 may lock the door 11 (step S14). ..

[Second Embodiment]
Next, the second embodiment will be described. The difference between the present embodiment and the first embodiment is that the door 11 is further unlocked based on an instruction from the terminal device 200. The points that are the same as those of the other embodiments will be omitted below.

The communication unit 101 communicates with the terminal device 200 by direct communication and communication via a communication network (WAN (Wide Area Network), LAN (Local Area Network), etc.).

The storage unit 110 stores the locking / unlocking conditions set from at least one of the strength of the signal received by the direct communication with the terminal device 200 and the instruction from the terminal device 200. Here, it is assumed that the instruction from the terminal device 200 is received by the communication unit 101 via the communication network.

The locking / unlocking control unit 122 locks / unlocks the door 11 based on at least one of the strength of the signal received from the terminal device 200 by direct communication and at least one of the instructions from the registered terminal device 200. Specifically, when the communication unit 101 receives an instruction to unlock the door 11 from the registered terminal device 200, the lock / unlock control unit 122 unlocks the door 11. In the following description, the instruction for unlocking the door 11 is referred to as an unlocking instruction.

Further, when the communication unit 101 receives an instruction to lock the door 11 from the registered terminal device 200, the lock / unlock control unit 122 may lock the door 11. In the following description, the instruction to lock the door 11 is referred to as a locking instruction. In the following description, for convenience of explanation, when the communication unit 101 does not receive the unlock instruction from the registered terminal device 200, the door 11 is assumed to be in the locked state.

For example, assume that the storage device 100 is a refrigerator arranged in the user's house of the terminal device 200. Then, it is assumed that a domestic servant is at home at the user's home when the user of the terminal device 200 goes out. Here, it is assumed that the door 11 is locked when the user of the terminal device 200 carries the terminal device 200 and goes out. Therefore, when the user of the terminal device 200 goes out, the domestic servant cannot take out the stored article (for example, food) from the storage device 100. When the communication unit 101 receives the unlock instruction from the registered terminal device 200, the lock / unlock control unit 122 unlocks the door 11. As a result, when the user of the terminal device 200 goes out, the domestic servant who is at home can take out the article (for example, food) stored in the storage device 100.

When the lock / unlock control unit 122 is unlocked based on the instruction from the registered terminal device 200, the lock / unlock control unit 122 may be locked after a predetermined time has elapsed from the unlocking.

Further, the locking / unlocking control unit 122 locks / unlocks the door 11 based on the locking / unlocking condition set from at least one of the strength of the signal received from the terminal device 200 by direct communication and the instruction from the terminal device 200. .. For example, the locking / unlocking control unit 122 may set whether or not the strength of the signal received from the registered terminal device 200 by direct communication exceeds a predetermined threshold value as a locking / unlocking condition.

Further, for example, the locking / unlocking control unit 122 may set the presence / absence of an instruction (for example, unlocking instruction or locking instruction) from the registered terminal device 200 as a locking / unlocking condition.

Further, for example, the locking / unlocking control unit 122 may set the strength of the signal received from the registered terminal device 200 by direct communication and the presence / absence of an instruction from the registered terminal device 200 as the locking / unlocking conditions. Good.

Further, for example, the locking / unlocking control unit 122 may set the acquisition of the registered user identification information via the input unit 102 as a locking / unlocking condition. In that case, when the lock / unlock control unit 122 acquires the registered user identification information via the input unit 102, the lock / unlock control unit 122 may unlock (or lock) the door 11.

The locking / unlocking control unit 122 may set (select) the locking / unlocking conditions based on the registered user's operation on the input unit 102. Here, of course, the user may input one or more locking / unlocking conditions into the input unit 102. In addition, for example, the user may set (select) the locking / unlocking condition by using the registered terminal device 200. Then, the registered terminal device 200 may transmit the set locking / unlocking conditions to the storage device 100.

Further, for example, the locking / unlocking control unit 122 determines whether or not there is an instruction from the terminal device 200 when the strength of the signal received from the terminal device 200 registered by the communication unit 101 by direct communication is smaller than a predetermined threshold value. It may be set as a condition for locking and unlocking.

Further, for example, the locking / unlocking control unit 122 locks / unlocks the presence / absence of an instruction from the terminal device 200 when the strength of the signal received from the terminal device 200 by the communication unit 101 is equal to or higher than a predetermined threshold value. It may be set as a condition of.

For example, the locking / unlocking control unit 122 may change the locking / unlocking conditions according to the time and time zone. In that case, the locking / unlocking control unit 122 may change the locking / unlocking conditions of the door 11 at a predetermined time or time zone. For example, the registered user may set a time and a time zone for changing the locking / unlocking conditions.

For example, it is assumed that the locking / unlocking control unit 122 sets the presence / absence of an instruction from the registered terminal device 200 as a locking / unlocking condition from 9:00 pm to 6:00 am. In that case, from 9:00 pm to 6:00 am, the locking / unlocking control unit 122 is registered even if the strength of the signal received from the terminal device 200 registered by the communication unit 101 by direct communication is equal to or higher than a predetermined threshold value. The door 11 is maintained in the locked state until the unlocking instruction from the terminal device 200 is received.

The locking / unlocking control unit 122 may control the locking / unlocking unit 105 so as to maintain the unlocked state (or the locked state). For example, the locking / unlocking control unit 122 locks / unlocks so as to maintain the unlocked state (or locked state) based on at least one of the operation of the registered user and the instruction from the registered terminal device 200. The lock portion 105 may be controlled.

The notification unit 123 notifies the registered terminal device 200 of a change in the open / closed state of the door 11 (at least one of the door 11 being opened and the door 11 being closed). Further, for example, the notification unit 123 may notify the terminal device 200 of the success or failure of locking / unlocking the door 11. Further, when the door 11 is open beyond a predetermined time, the notification unit 123 may notify the terminal device 200 that the door 11 is open. The above locking / unlocking conditions are an example, and the purpose is not to limit the locking / unlocking conditions to the above.

FIG. 7 is a flowchart showing an example of the operation of the storage device 100. In the following description, for convenience of explanation, when the storage device 100 and the terminal device 200 cannot directly communicate with each other and the communication unit 101 does not receive the unlock instruction from the registered terminal device 200, the door 11 Is in a locked state. Further, in the following description, as an example, whether or not the signal strength due to direct communication exceeds a predetermined threshold value is illustrated as a locking / unlocking condition, which is a locking / unlocking condition set in the storage device 100. It is not intended to limit. Further, in the following description, it is assumed that the locking / unlocking conditions may be changed at any time based on the operation of the registered user or the like. FIG. 7 shows an example of an operation of locking / unlocking the storage device 100 by using the terminal device 200, but this is not intended to limit the method of locking / unlocking the storage device 100.

In step S101, the locking / unlocking control unit 122 determines whether or not the locking / unlocking conditions for unlocking are set based on the strength of the signal by direct communication. If the locking / unlocking conditions for unlocking are set based on the strength of the signal obtained by direct communication (step S101: Yes), the process proceeds to step S102.

Similar to the first embodiment, in step S102, the locking / unlocking control unit 122 determines whether or not the strength of the signal received from the registered terminal device 200 by direct communication is equal to or higher than a predetermined threshold value. When the strength of the signal received from the registered terminal device 200 by direct communication is equal to or higher than a predetermined threshold value (step S102: Yes), the locking / unlocking control unit 122 unlocks the door 11 (step S103). .. Then, the control returns to step S101 and continues the process.

On the other hand, when the strength of the signal received from the registered terminal device 200 by direct communication is less than a predetermined threshold value (step S102: No), the locking / unlocking control unit 122 determines whether or not the door 11 is closed. Determine (step S104).

When the door 11 is closed (step S104: Yes), the locking / unlocking control unit 122 locks the door 11 (step S105). Then, the control returns to step S101 and continues the process. On the other hand, when the door 11 is not closed (step S104: No), the locking / unlocking control unit 122 waits until the door 11 is closed.

When the unlocking condition for unlocking based on the strength of the signal by direct communication is not set (step S101: No), the locking / unlocking control unit determines whether or not the unlocking instruction from the terminal device 200 has been received. 122 determines (step S106). If the unlock instruction from the terminal device 200 is not received (step S106: No), the control returns to step S101 and continues the process. On the other hand, when the unlocking instruction from the terminal device 200 is received (step S106: Yes), the locking / unlocking control unit 122 unlocks the door 11 (step S107). Then, the control returns to step S101 and continues the process. When the locking / unlocking control unit 122 unlocks the door 11 based on the unlocking instruction from the registered terminal device 200, the notification unit 123 tells that the unlocking is done by the sender of the unlocking instruction. The terminal device 200 may be notified.

When the lock / unlock control unit 122 unlocks the door 11 based on the unlock instruction from the terminal device 200, the lock / unlock control unit 122 closes the door 11 after the door 11 is opened. May be locked. In that case, when the lock / unlock control unit 122 locks the door 11, the control returns to step S101 and continues the process. For example, when the lock / unlock control unit 122 locks the door 11 after unlocking the door 11 based on the unlock instruction from the registered terminal device 200, the notification unit 123 indicates that the door has been locked. , The terminal device 200 that is the source of the unlocking instruction may be notified.

Note that the above flow is an example, and the present embodiment is not limited to this. For example, it is assumed that the locking / unlocking control unit 122 sets the strength of the signal received by direct communication from the registered terminal device 200 and the presence / absence of an instruction from the registered terminal device 200 as the locking / unlocking conditions. .. In that case, for example, when the strength of the signal received from the registered terminal device 200 by direct communication is smaller than a predetermined threshold value, the locking / unlocking control unit 122 doors based on the instruction from the registered terminal device 200. 11 may be unlocked. According to the present embodiment, the user of the registered terminal device 200 can use the registered terminal device 200 to unlock the storage device 100 from, for example, a remote location. Further, according to the present embodiment, the registered user can change the locking / unlocking conditions based on the operation on the registered terminal device 200 or the operation on the input unit 102.

The present invention is not limited to the above-described embodiment, and is substantially the same as the configuration shown in the above-described embodiment, has the same effect and effect, or can achieve the same object. May be replaced with.
