Description

Technical Field

[0001] The present invention relates to a locking and unlocking system for controlling the locking and unlocking of an object to be locked.

Background Art

[0002] For example, in a locking and unlocking system using a so-called smart lock that controls the locking and unlocking of a door with a digitized key, there is a system that enables temporary unlocking of the door by using a so-called one-time password as shown in Patent Document 1. In such a system, the one-time password is transmitted from, for example, a key management cloud to a mobile terminal and used by a door unlocking device. If the one-time password has a short usable time, the risk of leakage and unauthorized use is reduced, and the security of the locking and unlocking system can be improved.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, if the one-time password is set to be usable for only a short time, a person trying to unlock the door has to obtain the one-time password near the door. Obtaining the one-time password can be done, for example, simply by operating a mobile terminal. At first glance, it seems easy, but it is troublesome for a person whose hands are occupied, such as a person whose hands are full with luggage. For example, if a delivery person with hands full of luggage tries to obtain the one-time password by operating a mobile terminal, they have to put down the luggage in their hands once, which is a burden.

[0005] These issues concerning the convenience and security of locking and unlocking systems are problems that can occur in locking and unlocking systems other than door locking and unlocking systems as well.

[0006] Therefore, the present invention has been made to solve the above problems, and aims to provide a locking and unlocking system that can reduce the effort involved at the unlocking site while also reducing the risk of unauthorized use of unlocking data. [Means for solving the problem]

[0007] The present invention has the following configuration.

[0008] [1] A locking and unlocking system comprising a locking and unlocking control device for controlling the locking and unlocking of an object to be locked, and a portable terminal capable of communicating with the locking and unlocking control device, The aforementioned mobile terminal is An unlocking data storage unit that stores unlocking data for unlocking a locked object, The system includes an unlocking request unit that outputs the unlocking data stored in the unlocking data storage unit, The locking / unlocking control device has a lock control unit that receives the unlocking data output from the unlocking request unit, determines whether or not it is registered in advance, and outputs an unlocking command signal to the object to be locked if it is determined to be registered in advance. The locking and unlocking system is characterized in that the mobile terminal further has a deletion unit that deletes the unlocking data output from the unlocking request unit from the unlocking data storage unit when it determines that the unlocking data output from the unlocking request unit has been used to unlock the object to be locked.

[0009] With a locking and unlocking system configured in this way, unlocking data can be stored in the mobile device in advance, eliminating the need to retrieve unlocking data from the mobile device near the unlocking site. Furthermore, used unlocking data is deleted from the mobile device, so the data does not remain on the mobile device, reducing the risk of it being leaked and misused, for example. Furthermore, since used unlocking data is deleted from the mobile device, there is no need to change or reconfigure the unlocking data registered on the lock / unlock control device. This simplifies the lock / unlock system.

[0010] [2] The aforementioned deletion section is, The locking and unlocking system according to [1], wherein the lock control unit determines that the unlocking data has been used when it receives the unlocking data from the unlocking request unit, determines that the unlocking data has been registered in advance, or outputs the unlocking command signal to the object to be locked. With this configuration, feedback can be received from the lock control unit, and unlocking data that is determined to have been used with a higher degree of certainty can be deleted.

[0011] [3] The aforementioned locking / unlocking control device is It is installed at the site where the object to be locked is located, and is configured to communicate directly with the mobile terminal. The system further includes an unlocking completion signal transmission unit that outputs an unlocking completion signal indicating that the unlocking of the object to be locked has been completed. The locking / unlocking system according to [1]~[2], wherein the deletion unit determines that the unlocking data has been used when it receives an unlocking completion signal from the unlocking completion signal transmission unit, or when communication between the mobile terminal and the locking / unlocking control device is disconnected. With this configuration, unlocking data can be directly transmitted from a mobile device to the lock / unlock control device at the site where the object to be locked is located. This means that the object can be unlocked even in locations without a network environment. Furthermore, the risk of unauthorized use can be reduced by deleting used unlocking data, regardless of the network environment. This makes it possible to build a highly secure locking and unlocking system even in locations where conventional smart locks cannot be used due to poor network conditions.

[0012] [4] The object to be locked is a door, The locking / unlocking control device further includes a person detection sensor that detects a person present within a predetermined area of ​​the door. The locking / unlocking system according to [1] to [3], wherein the deletion unit determines that the person detected by the person detection sensor has passed through the door, and determines that the unlocking data has been used. With this configuration, the unlock data is deleted only when the door is opened and a passerby actually passes through (uses) the door. This prevents the accidental deletion of unlock data when no one has actually passed through the door.

[0013] [5] The aforementioned deletion section is, If a person who was detected within the predetermined area while the door is unlocked is no longer detected, or moves in a direction that passes through the door, The locking / unlocking system according to [4] determines that the detected person has passed through the door. With this configuration, lock / unlock data is deleted only after sufficient information has been obtained from the human detection sensor, allowing for the deletion of unlock data that is determined to have actually been used with a higher degree of accuracy.

[0014] [6] The locking and unlocking system according to any one of [1] to [5], wherein the deletion unit deletes the unlocking data output from the unlocking request unit from the unlocking data storage unit when it determines that the unlocking data has been used a predetermined number of times to unlock the object to be locked. When you want to unlock an object multiple times, if the unlock data is deleted after each use, you have to retrieve the unlock data for each use, which is time-consuming. With the configuration in [6], however, the unlock data can be used a predetermined number of times, improving convenience. While increasing the number of uses also increases the risk of unauthorized use, a balance between convenience and security can be struck by appropriately setting the predetermined number of uses.

[0015] [7] The unlocking data deletion unit deletes unlocking data from the unlocking data storage unit that has elapsed a predetermined period since it was determined to be used for the first time or since it was determined to be used last. The unlocking and locking system according to any one of [1] to [5]. With such a configuration, the unlocking data can be used multiple times within a predetermined period from the first use, or the unlocking data can be continuously used as long as it is used continuously without an interval. This is convenient when the locked object must be unlocked multiple times continuously within a certain period, for example, when a moving company needs to pass through an auto-lock door multiple times. If the predetermined period during which it can be used is long, the risk of unauthorized use also increases, but by appropriately setting the predetermined period, it is possible to achieve a balance between this convenience and security.

[0016] [8] The unlocking and locking system further includes a management server capable of communicating with the mobile terminal via a network. The management server further includes a server storage unit for storing unlocking data, and an unlocking authority granting unit for outputting the unlocking data stored in the server storage unit. The mobile terminal further has an unlocking authority acquisition unit that transmits user data for identifying the user carrying the mobile terminal to the unlocking authority granting unit, and stores the received unlocking data in the unlocking data storage unit when receiving the unlocking data from the unlocking authority granting unit. The unlocking authority granting unit determines whether the user data received from the unlocking authority acquisition unit is pre-registered, and transmits the unlocking data to the unlocking authority acquisition unit when it is determined to be pre-registered. The unlocking and locking system according to [1] to [7]. With such a configuration, for example, the unlocking data can be given only to registered mobile terminals, so the risk of unauthorized use of the unlocking data can be reduced.

[0017] [9] The locking / unlocking system according to [4] or [5], wherein the mobile terminal and the locking / unlocking control device begin communicating after the person detection sensor detects a person. With this configuration, the door can be unlocked only when a user is actually near it.

[0018]

[10] A delivery system equipped with the locking / unlocking system described in [4], [5], or [9]. Leave-at-door delivery is primarily used for delivering packages to homes where no one is home. In apartment buildings and similar structures, if the designated delivery location is inside a locked door, such as a shared entrance, the resident receiving the package cannot unlock that door. In contrast, if, for example, a smart lock system using one-time passwords is installed on the door of the delivery destination, such as an apartment building, the delivery person can obtain the one-time password to unlock the lock by performing a prescribed operation on their mobile device. However, delivery drivers often have both hands full with packages to deliver, and in order to operate a mobile device to obtain a one-time password, they need to put the package down on the ground or otherwise release their hands. Having to put the package down near the door every time a package is left unattended is a significant burden for delivery companies, and there are times when it's impossible to put the package down, such as on rainy days. To address these issues, with the configuration of

[10] , unlocking data for unlocking the door at the delivery destination is stored in the mobile terminal in advance, so the delivery person does not need to operate the mobile terminal to obtain unlocking data at the delivery destination, and can reduce the hassle of having to put the package down in front of the door, for example, when their hands are full with the package. Furthermore, since used unlocking data is deleted, the unlocking data does not remain on the mobile terminal 200 after the delivery is completed, reducing the risk of misuse by delivery personnel outside of work hours or the leakage of unlocking data. [Effects of the Invention]

[0019] According to the present invention configured in this manner, it is possible to provide a locking and unlocking system that reduces the effort involved in unlocking while also reducing the risk of unauthorized use of unlocking data. [Brief explanation of the drawing]

[0021] One embodiment of the locking and unlocking system according to the present invention will be described with reference to the drawings.

[0022] [First Embodiment] 1. System Overview The locking and unlocking system according to the first embodiment is installed, for example, in the common entrance (hereinafter also simply referred to as the entrance) of a multi-unit residential building such as an apartment building, and is used to unlock an automatic door that is locked by an auto-lock or the like for a temporary facility user (in this case, a delivery person). In this locking and unlocking system, delivery companies can obtain in advance the unlocking data necessary to unlock the automatic doors of the apartment buildings where deliveries are made. In this embodiment, the locked state of the automatic door refers to the closed state of the door, and the unlocked state refers to the open state of the door.

[0023] 2. System Configuration 2-1. Overall Structure As shown in Figures 1 to 3, this locking and unlocking system is configured using a management server 100 that manages unlocking data for unlocking the automatic door D, a portable terminal 200 carried by the delivery person, and a locking and unlocking control device 300 that is installed near the automatic door D and controls the locking and unlocking of the automatic door D.

[0024] The unlocking data is the key required for the lock / unlock control device 300 to unlock the automatic door D, and is, for example, a password pre-set in the lock / unlock control device 300.

[0025] The management server 100 and the mobile terminal 200 can send and receive signals and data to each other via a network N such as the internet or a telephone line, and the mobile terminal 200 and the lock / unlock control device 300 can directly send and receive signals and data to each other via one-to-one local communication, such as using BLE.

[0026] 2-2. Management Server 100 The management server 100 centrally manages the unlocking data from locking / unlocking control devices 300 installed in multiple apartment buildings and the like. The management server 100 is a computer equipped with a CPU, memory, communication interface, etc., and is configured to communicate with external devices via the network N, etc., as shown in Figure 1. The management server 100 may also be a virtual computer located on the cloud.

[0027] The management server 100 functions as a server storage unit 11 and an unlocking authority granting unit 12 through the cooperation of the CPU and peripheral devices according to a predetermined program stored in memory.

[0028] 2-2-1. Server storage unit 11 The server storage unit 11 is set in a predetermined area of ​​the memory of the management server 100. As shown in Figure 3, this server storage unit 11 stores a database that links property IDs of apartment buildings, etc., device IDs of lock / unlock control devices 300 installed in those apartment buildings, etc., and unlock data from the lock / unlock control devices 300.

[0029] In this property database, the aforementioned property IDs are also linked to the user IDs of delivery service providers who are authorized to use the apartment buildings indicated by the property IDs (in this case, for unattended delivery).

[0030] 2-2-2. Unlocking authorization unit 12 The unlocking authorization unit 12 refers to the property database to check whether the delivery service provider is authorized to leave packages at the apartment building where the delivery service provider is requesting unlocking. If authorized, it outputs unlocking data for the lock / unlock control device 300 installed in the apartment building. The unlocking authorization unit 12 of this embodiment refers to the property database and outputs unlocking data along with the device ID of the lock / unlock control device 300 associated with that unlocking data.

[0031] 2-3. Mobile devices 200 The mobile terminal 200 is equipped with input / output devices such as a CPU, memory, and touch panel display, as well as a communication interface, and is, for example, a smartphone, tablet, or personal computer. As shown in Figure 1, the mobile terminal 200 is configured to communicate with external devices via the network N or Bluetooth® Low Energy (so-called BLE). The mobile terminal 200 may also be a BLE tag equipped with a microcontroller.

[0032] The mobile terminal 200 functions as at least a user data storage unit 21, an unlocking authority acquisition unit 22, an unlocking data storage unit 23, and an unlocking request unit 24, through the cooperation of the CPU and peripheral devices according to a predetermined program stored in memory.

[0033] 2-3-1. User data storage unit 21 The user data storage unit 21 is set in a predetermined area of ​​the memory of the mobile terminal 200. This user data storage unit 21 pre-stores user data (in this case, a user ID, which is an identification number for each delivery service provider) that identifies users of the locking / unlocking system who carry the mobile terminal 200. The user ID may be, for example, a service provider ID indicating the delivery company to which the delivery service provider belongs, or an employee ID of the delivery service provider.

[0034] In this embodiment, the user ID is stored in the user data storage unit 21 as part of the shipping label (delivery slip) data.

[0035] This slip data pertains to packages handled by delivery personnel who possess a mobile terminal 200, and includes linked information such as the contents of the package, information to identify the delivery destination or origin, and information indicating delivery conditions. In this case, it includes at least a property ID that identifies the apartment building or other structure at the delivery destination.

[0036] As shown in Figure 4, the user data storage unit 21 of this embodiment stores a document database containing document data for multiple packages.

[0037] 2-3-2. Unlocking Authority Acquisition Unit 22 The unlocking authority acquisition unit 22 transmits the property ID and user ID to the unlocking authority granting unit 12 and requests the granting of unlocking data for the lock / unlock control device 300 installed in the apartment building, etc., indicated by the property ID. The unlocking authority acquisition unit 22 only needs to transmit at least the information necessary to identify the lock / unlock control device 300 to the unlocking authority granting unit 12, and may transmit only the device ID and user ID, for example.

[0038] When the unlocking authority acquisition unit 22 receives unlocking data from the unlocking authority granting unit 12, it stores this data in the unlocking data storage unit 23, which will be described later. In this embodiment, the unlocking authority acquisition unit 22 associates the unlocking data received from the unlocking authority granting unit 12 with the device ID and stores it in the unlocking data storage unit 23.

[0039] The unlocking authority acquisition unit 22 in this embodiment is configured to acquire unlocking data necessary for the delivery of packages handled by the delivery service provider by referring to the slip data stored in the user data storage unit 21.

[0040] The unlocking rights acquisition unit may automatically acquire unlocking data by referring to the slip data, or it may acquire unlocking data when the delivery person performs a predetermined operation on the mobile terminal 200.

[0041] 2-3-3. Unlocking data storage unit 23 The unlocking data storage unit 23 is set in a predetermined area of ​​the memory of the mobile terminal 200. This unlocking data storage unit 23 stores unlocking data linked to the device ID of the locking / unlocking control device 300 that the unlocking data locks or unlocks. The unlocking data storage unit 23 can store unlocking data from multiple locking / unlocking control devices 300.

[0042] Furthermore, as long as the delivery service provider performs the operations necessary for their normal duties, the unlocking data stored in the unlocking data storage unit 23 is kept secret from the person operating the mobile terminal 200 and is configured not to be disclosed, for example, through a display.

[0043] In this embodiment, the unlocking data stored in the unlocking data storage unit 23 is obtained from the management server, but the unlocking data storage unit 23 may also store unlocking data obtained by other means. For example, the unlocking data storage unit 23 may have in advance stored unlocking data input from an input unit such as a touch panel of a mobile terminal, or unlocking data obtained from other devices via wired communication.

[0044] 2-3-3. Unlocking Request Unit 24 The unlock request unit 24 outputs the unlock data stored in the unlock data storage unit 23 and requests the automatic door to be unlocked.

[0045] 2-4. Locking / unlocking control device 300 As shown in Figures 1 to 3, the lock / unlock control device 300 receives unlocking data from the mobile terminal 200 and controls the locking and unlocking of the automatic door D. It is installed near the automatic door D (in this case, on the door frame) and is equipped with an information processing device P.

[0046] Furthermore, the locking / unlocking control device 300 of this embodiment further includes a human detection sensor that detects a person entering a predetermined detection area AR. The locking / unlocking control device 300 of this embodiment is a door sensor device that houses the information processing device P and the human detection sensor S in a single housing. Note that the information processing device P and the human detection sensor S may be housed in different housings.

[0047] 2-4-1. Human detection sensor S As shown in Figure 3, the human detection sensor S detects whether a person has entered the detection area AR, which is set near the outside of the doorway area, and outputs a detection signal indicating this. Specifically, various types of human detection sensors can be used, such as passive infrared sensors, active infrared sensors, radar sensors using microwaves or millimeter waves, or camera sensors using image sensors.

[0048] 2-4-2. Information Processing Device P The information processing device P is a so-called computer equipped with a CPU, memory, I / O interface, communication interface, etc., and as shown in Figure 1, it is configured to communicate with external devices via BLE or the like.

[0049] This information processing device P functions as a lock control unit 31 and an unlocking completion signal transmission unit 34, through the cooperation of the CPU and peripheral devices according to a predetermined program stored in the memory.

[0050] The memory of the information processing device P pre-stores a device ID for identifying the lock / unlock control device 300 and unlocking data for the said lock / unlock control device 300. The unlocking data stored in the memory is pre-registered when the lock / unlock control device 300 is shipped or installed. Multiple sets of this pre-registered unlocking data may be registered.

[0051] 2-4-3. Lock control unit 31 As shown in Figure 3, the lock control unit 31 includes an unlock data authentication unit 32 that authenticates unlock data, and an unlock command signal transmission unit 33 that outputs an unlock command signal to the opening / closing drive device D1 of the automatic door D based on the authentication result.

[0052] The unlocking data authentication unit 32 determines whether the unlocking data received from the unlocking request unit 24 is pre-registered, and if it determines that the unlocking data is pre-registered, it determines that the authentication of the unlocking data has been successful. In this embodiment, if the received unlocking data matches unlocking data that is pre-stored in the memory of the information processing device P, it is determined that the authentication has been successful.

[0053] The unlock command signal transmission unit 33 outputs an unlock command signal based on the authentication result of the unlock data authentication unit 32. In this embodiment, however, the unlock command signal is output not only based on this authentication result but also based on the detection signal output from the human detection sensor S.

[0054] In other words, the lock control unit 31 of this embodiment outputs an unlock command signal when the unlock data authentication unit 32 determines that authentication has been successful and the human detection sensor S detects a person.

[0055] 2-4-5. Unlocking completion signal transmitter 34 The unlocking completion signal transmission unit 34 outputs an unlocking completion signal indicating that the automatic door D has been unlocked. Specifically, when the unlocking completion signal transmitting unit 34 receives a signal from the opening / closing drive device D1 of the automatic door D indicating that the door opening operation (unlocking operation) has been completed, it determines that the automatic door D has been unlocked and outputs an unlocking completion signal.

[0056] 2-5. Deleted section 25 However, the mobile terminal of this embodiment also functions as a deletion unit 25. The deletion unit 25 deletes the unlocking data output from the unlocking request unit 24 from the unlocking data storage unit 23 when it determines that the unlocking data output from the unlocking request unit 24 has been used to unlock the automatic door D.

[0057] In this embodiment, the deletion unit 25 determines that the unlocking data has been used when it receives an unlocking completion signal from the unlocking completion signal transmission unit 34 after outputting unlocking data from the unlocking request unit 24, and deletes this used unlocking data. The deletion unit 25 may also effectively delete unlocking data that could be used for unlocking by modifying and invalidating the unlocking data in the unlocking data storage unit 23, or by changing the status of the unlocking data to an unusable state. The deleted unlocking data should be erased in a way that prevents recovery.

[0058] 3. System Operation 3-1. Pre-acquisition of unlocking data As shown in Figure 3, when a delivery driver operates a mobile terminal 200 and selects a package from the delivery slip database, the unlocking authority acquisition unit 22 transmits the property ID of the delivery destination associated with that package and the user ID of the delivery driver to the unlocking authority granting unit 12 (step S1).

[0059] The unlocking authority granting unit 12 searches the property database and determines whether the delivery service provider indicated by the received user ID is permitted to leave packages at the apartment building indicated by the received property ID (step S2).

[0060] If it is determined that delivery to a designated location is permitted, the unlocking data for the automatic door D of the apartment building is transmitted to the unlocking authority acquisition unit 22 along with the device ID of the locking / unlocking control device of the automatic door D (step S3).

[0061] The unlocking authority acquisition unit 22 associates the received unlocking data with the device ID and stores it in the unlocking data storage unit 23 (step S4).

[0062] Thus, the prior acquisition of unlocking data may be performed manually, or it may be performed automatically for packages whose distance to the delivery destination, such as an apartment building, falls below a predetermined distance, based on location information such as GPS built into the mobile terminal 200.

[0063] In addition, in step S2, the selected slip data may be transmitted to the unlocking authorization unit 12.

[0064] 3-2. Unlocking automatic doors As shown in Figure 4, when a delivery person arrives at the entrance of the apartment building where the delivery is being made and enters the predetermined detection area AR, the human detection sensor S emits a detection signal.

[0065] When the information processing device P receives this detection signal (step S11), it uses BLE to transmit a beacon signal indicating the device ID of the lock / unlock control device 300 to a predetermined reception range (step S12).

[0066] If the device ID indicated by the received beacon signal is one of those stored in the storage compartment, the mobile terminal 200 of the delivery service provider attempts local communication with the lock control unit 31 of the lock / unlock control device 300 (step S13).

[0067] When local communication is established, the unlock request unit 24 identifies the data corresponding to the device ID indicated by the beacon signal from the unlock data storage unit 23 and transmits it to the unlock data authentication unit 32 (steps S14, S15).

[0068] The unlocking data authentication unit 32 determines whether the received unlocking data matches pre-registered unlocking data, that is, whether the delivery person has the authority to unlock the door (step S16).

[0069] If it is determined that the user has the authority to unlock the door, and the unlock command signal transmission unit 33 has received a detection signal from the human detection sensor S, the unlock command signal transmission unit 33 transmits an unlock command signal to the opening / closing drive device D1 (step S17) to open (unlock) the automatic door D.

[0070] 3-3. Deleting used unlocking data When the opening / closing drive device D1 opens the automatic door D, it sends a signal to the unlocking completion signal transmitting unit 34 to indicate this. Upon receiving this signal, the unlocking completion signal transmitting unit 34 determines that the unlocking of the automatic door D is complete and sends an unlocking completion signal to the deletion unit 25 (step S21).

[0071] Upon receiving the unlocking completion signal, the deletion unit 25 determines that the unlocking data was used to unlock the automatic door D and deletes the used unlocking data from the unlocking data storage unit 23 (step S22). The deletion unit 25 may also delete the used unlocking data from the unlocking data storage unit 23 if the mobile terminal 200 that received the unlocking completion signal disconnects local communication with the locking / unlocking control device 300.

[0072] The unlocking completion signal transmission unit 34 may also determine that the unlocking of the automatic door D is complete and output an unlocking completion signal when the unlocking data authentication unit 32 receives unlocking data (step S15), when the unlocking data authentication is successful (step S16), or when the unlocking command signal transmission unit 33 outputs an unlocking command signal (step S17).

[0073] 4. Effects of the First Embodiment With the locking and unlocking system of the first embodiment configured in this way, unlocking data can be stored in the mobile terminal 200 in advance. Therefore, the delivery person does not need to operate the mobile terminal 200 to obtain unlocking data near the automatic door D, and can reduce the hassle of, for example, putting down the package in front of the door.

[0074] Since used unlocking data is deleted, the unlocking data does not remain on the mobile terminal 200 after delivery is completed, reducing the risk of it being leaked and misused, for example.

[0075] Since the unlocking data stored in the mobile terminal 200 is configured not to be disclosed to the person operating the mobile terminal 200, the risk of leakage of the unlocking data itself can be reduced while still storing it in the mobile terminal 200.

[0076] Since used unlocking data is deleted from the mobile terminal 200, there is no need to change or reset the pre-registered unlocking data in the lock / unlock control device 300. This simplifies the lock / unlock system.

[0077] Since the unlocking data is deleted based on the unlocking completion signal from the lock / unlock control device 300, unlocking data that is determined to have been used with a higher degree of certainty can be deleted.

[0078] By the way, conventional smart lock systems that use one-time passwords require, for example, obtaining a one-time password from a key management cloud to a mobile device via the network near the door, making them difficult to apply to locations with unstable network environments near the door.

[0079] In contrast, with the locking and unlocking system of this embodiment, unlocking data can be directly transmitted from the mobile terminal 200 to the locking and unlocking control device 300 at the entrance of an apartment building where the automatic door D is installed. Therefore, even at entrances without a network environment (or with an unstable network environment), the automatic door D can be reliably unlocked. Furthermore, the risk of unauthorized use can be reduced by deleting used unlocking data, regardless of the network environment.

[0080] Since the lock / unlock control device 300 is configured to transmit a beacon only after the human detection sensor S detects a person, it is possible to reduce unnecessary transmission of beacons to the surrounding area.

[0081] Since the automatic door D is unlocked based on both human detection by the human detection sensor S and authentication of unlocking data, a more secure locking and unlocking system for the automatic door D can be constructed compared to a system where the door unlocking is controlled by only one of these methods.

[0082] Since the system is configured to obtain unlocking data on the mobile terminal 200 only when authentication by the management server 100 is successful, the risk of unauthorized use of the unlocking data can be reduced.

[0083] In the first embodiment, the mobile terminal 200 can be a general-purpose mobile terminal such as a smartphone, and the locking / unlocking control device 300 is configured as a door sensor device. With this configuration, the smart lock system according to the present invention can be introduced into an automatic door system simply by preparing this door sensor device as dedicated hardware. In addition, it can be introduced regardless of the network environment of the entrance to apartment buildings, etc., thus reducing the effort and cost of introduction.

[0084] [Second Embodiment] The unlocking completion signal transmitting unit in the above embodiment outputs an unlocking completion signal when it receives a predetermined signal from the opening / closing drive device D1 of the automatic door D. In contrast, the unlocking completion signal transmitting unit of the second embodiment outputs an unlocking completion signal based on a predetermined signal received from the opening / closing drive device D1 of the automatic door D and a detection signal received from the human detection sensor S.

[0085] Here, when a predetermined signal is received from the opening / closing drive device D1, and the person detected by the person detection sensor S within the detection area AR is no longer detected, or moves in a direction to pass through the doorway area, the unlocking completion signal transmission unit determines that the unlocking data has been used and that the person has passed through the automatic door, and outputs an unlocking completion signal.

[0086] With a locking / unlocking system configured in this way, locking / unlocking data is deleted only after sufficient information has been obtained from the detection sensor, making it possible to delete unlocking data that is determined to have actually been used with a higher degree of accuracy.

[0087] [Third Embodiment] The deletion unit in each of the above embodiments deleted unlocking data that had been used once. In contrast, the deletion unit of the third embodiment deletes the unlocking data from the unlocking data storage unit when it determines that the unlocking data output from the unlocking request unit has been used a predetermined number of times to unlock the automatic door.

[0088] The deletion unit here deletes unlocking data if the number of times an unlocking completion signal has been received as a result of that unlocking data being output from the unlocking request unit exceeds a predetermined number. The number of times an unlocking completion signal has been received is linked to the unlocking data and stored in the unlocking data storage unit.

[0089] This improves convenience because the unlock data can be used a predetermined number of times. While increasing the number of uses also increases the risk of misuse, this trade-off between convenience and security can be balanced by appropriately setting the predetermined number of uses.

[0090] [Fourth Embodiment] The deletion unit of the fourth embodiment deletes unlocking data from the unlocking data storage unit after a predetermined period has elapsed since it was determined to have been used for the first time or last time.

[0091] The deletion unit here deletes unlocking data when a predetermined period has elapsed since the first time an unlocking completion signal was received as a result of the unlocking data being output from the unlocking request unit, or since the last time an unlocking completion signal was received. The time elapsed since the unlocking completion signal was received is linked to the unlocking data and stored in the unlocking data storage unit.

[0092] This allows unlocking data to be used multiple times within a specified period from the initial use, or to continue using the data as long as it is used continuously without any breaks. This is useful when an automatic door needs to be unlocked repeatedly within a certain period, for example, when a moving company needs to pass through an auto-locking door multiple times.

[0093] While a longer usage period increases the risk of misuse, this trade-off between convenience and security can be balanced by appropriately setting a predetermined period. [Other embodiments]

[0094] The unlocking data should be transmitted and received in an encrypted state between the management server and the mobile terminal, or between the mobile terminal and the locking / unlocking device. In this case, for example, the lock control unit can determine whether the unlocking data received from the mobile terminal is pre-registered by checking whether the decrypted unlocking data matches the unlocking data pre-stored in the memory of the information processing device. This reduces the risk of unlocking data being leaked, even if, for example, a third party intercepts communication between a mobile device and the locking / unlocking device.

[0095] In each of the above embodiments, the unlock command signal transmission unit outputs an unlock command signal based on the authentication result of the unlock data and the detection status of the human detection sensor. However, it is also possible to output an unlock command signal based solely on the authentication result of the unlock data. In each of the embodiments described above, the deletion unit deleted used unlocking data, but the locking / unlocking system may also delete locking data for locking the automatic door after use.

[0096] The deletion unit may delete the unlocking data after a predetermined time has elapsed following the output of the unlocking request unit. This allows for the deletion of unlocking data that may have been used, thereby improving security. Furthermore, if the specified period is too short, the unlocking data will be deleted immediately after output, making it unusable. However, by adjusting the length of the specified period, usability can be ensured. Furthermore, the deletion unit may delete the used unlocking data from the unlocking data storage unit 23 if local communication between the mobile terminal and the locking / unlocking device is interrupted, regardless of the unlocking status at that time. This allows for the deletion of potentially used unlocking data regardless of whether the unlocking was successful or not, thereby improving security.

[0097] If the unlocking data storage unit contains multiple related unlocking data, and one of them is deleted as used unlocking data, the deletion unit may also delete the other related unlocking data together. This makes it convenient to delete unlocking data linked to multiple packages delivered to the same apartment building or similar address all at once when all packages are delivered in a single delivery.

[0098] If the deletion unit deletes unlocking data, information indicating that the unlocking data was used (i.e., that a delivery was made) may be added to the slip data referenced to retrieve the deleted unlocking data.

[0099] The locking / unlocking systems in each of the above embodiments consisted of a management server, a mobile terminal, and a locking / unlocking control device, but the physical configuration of the locking / unlocking system according to the present invention is not limited to these. For example, the locking / unlocking system may consist of a mobile terminal and a locking / unlocking control device. The point is that the locking / unlocking system should be such that the unlocking data transmitted from the mobile terminal to the locking / unlocking control device and used to unlock the object to be locked by the locking / unlocking control device is deleted from the mobile terminal.

[0100] The locking / unlocking control device may be configured to communicate with external devices via a network N or the like. In this case, the locking / unlocking device may function as a lock control unit by remotely controlling the locking and unlocking of the object to be locked.

[0101] A signal indicating that the unlock data has been deleted may be sent from the mobile device to the management server. This allows the management server to manage the status of the assigned unlocking data, thereby improving security.

[0102] Furthermore, the management server may send a delete command signal to the mobile terminal instructing it to delete the unlock data stored in the unlock data storage unit. This allows unlocking data, once assigned, to be deleted from the management server in accordance with changes in circumstances, thereby improving security.

[0103] The information processing device and the human detection sensor may be provided in separate units.

[0104] The locking and unlocking systems of the above embodiments controlled the locking and unlocking of automatic doors, which are the objects to be locked. However, they may also control the locking and unlocking of manual doors, or the locking and unlocking of objects other than doors.

[0105] For example, the present invention may be applied to a locking / unlocking system that controls the locking and unlocking of a gate that restricts the movement of vehicles, or to a car-sharing system where the vehicle is locked to anyone other than the user. The present invention is a locking / unlocking system in which used unlocking data used to unlock an object is deleted from the mobile terminal. [Explanation of Symbols]
