Description

Technical Field

[0001] The present invention relates to an unlocking control server, an unlocking control system, an unlocking control program, and an unlocking control method for controlling unlocking of a locking mechanism in a multi-unit building.

Background Art

[0002] Conventionally, a locking mechanism in a multi-unit building such as an apartment complex is unlocked by a responder performing an unlocking operation after a call is made between an intercom slave unit installed at the entrance and an intercom master unit installed in each living room within the multi-unit building.

[0003] For example, Japanese Unexamined Patent Application Publication No. 2024-058028 proposes a shared entrance device that includes a wireless communication unit that performs wireless communication with one or more of an entrance slave unit provided at a doorway, a master unit provided in a shared facility, and a relay device, a wired communication unit that performs wired communication with the relay device, and a setting unit that sets which of the wireless communication unit and the wired communication unit is to be used for communication with the relay device (Patent Document 1).

Summary of Invention

Problems to be Solved by the Invention

[0005] However, in multi-unit buildings that only have existing intercom facilities, including the invention described in Patent Document 1, when a delivery worker delivers packages, the delivery worker calls from the intercom for each delivery destination to have the entrance door unlocked. This is because even if the delivery worker is allowed to enter the multi-unit building through unlocking by one delivery destination, if the delivery worker goes directly to another delivery destination without calling via the intercom, the resident at that delivery destination cannot confirm who the visitor is, which poses a security problem.

[0006] For the reasons mentioned above, delivery personnel cannot move freely within the building to make deliveries. Instead, they have to return to the entrance after completing a delivery to each address, call the next address via intercom, and have the door unlocked. This is an extremely roundabout process, and the more addresses there are within the building, the greater the physical burden on the delivery personnel and the longer the delivery time becomes.

[0007] On the other hand, intercom systems have the problem of being difficult to implement because they involve expensive equipment and installation costs, as well as the need to enter individual rooms for installation work. In particular, in apartment buildings, if the intercom system malfunctions due to aging or other reasons, unexpected repair and replacement costs will be incurred depending on the number of rooms, making it difficult to address the issue immediately from a budgetary standpoint.

[0008] The present invention was made to solve these problems and aims to provide an unlocking control server, unlocking control system, unlocking control program, and unlocking control method that can control the unlocking of locking mechanisms in apartment buildings with an inexpensive configuration without using intercom equipment, reduce the physical burden on delivery personnel and delivery time, and improve delivery efficiency.

[0009] Furthermore, the description of the problems mentioned above does not preclude the existence of other problems. Also, one aspect of the present invention does not need to solve all of the problems mentioned above. Moreover, it is possible to extract problems other than those mentioned above from the description, drawings, and claims. [Means for solving the problem]

[0023] Hereinafter, embodiments of the unlock control server, unlock control system, unlock control program, and unlock control method according to the present invention will be described with reference to the drawings.

[0024] As shown in Figure 1, the unlock control system 100 of the present embodiment is mainly composed of a delivery worker terminal 10 used by a delivery worker, a resident terminal 11 used by a resident at the delivery destination, an unlock signal output device 12 that outputs an unlock signal for unlocking the locking mechanism 13, a locking mechanism 13 provided at the entrance door (front entrance) or the like of a multi-unit building, and an unlock control server 1 that controls the unlocking of the locking mechanism 13. Each component will be described below.

[0025] In this invention, the term "apartment building" includes not only apartment buildings, dormitories, and company housing, but also all buildings that consist of multiple rooms or sections that can serve as delivery destinations, such as office buildings housing multiple companies, mixed-use buildings housing various shops, commercial facilities such as department stores and shopping malls, educational facilities such as universities and vocational schools, research facilities of public institutions, medical facilities such as hospitals, and accommodation facilities such as hotels.

[0026] [1] Delivery driver terminal 10 As shown in Figure 1, the delivery person terminal 10 is a terminal used by the delivery person and is composed of a computer such as a smartphone or tablet. In this embodiment, a delivery person terminal program is installed on the delivery person terminal 10. The delivery person terminal 10 then executes the delivery person terminal program to perform the functions described later.

[0027] Specifically, the delivery person terminal 10 has a reading function that reads a two-dimensional code using a built-in camera or the like. In this embodiment, the two-dimensional code is a QR code (registered trademark) and, as shown in Figure 1, is installed near the locking mechanism 13, such as on the entrance door of an apartment building.

[0028] In this embodiment, as shown in Figure 1, two types of two-dimensional codes are provided: one for delivery personnel and residents, and another for visitors. The two-dimensional codes for delivery personnel and residents have a property ID embedded in them that identifies the apartment building. On the other hand, the two-dimensional code for visitors has a URL (Uniform Resource Locator) embedded in it that is a website for visitors to call residents within the apartment building.

[0029] Furthermore, the two-dimensional code is not limited to a matrix type; a stack type is also acceptable. Additionally, the two-dimensional code is not limited to a static type; a dynamic two-dimensional code with a set validity period is also acceptable. In this case, a new two-dimensional code is generated and displayed on a display installed in the entrance, etc., at predetermined intervals (for example, every minute). This prevents unauthorized use, such as saving the two-dimensional code as an image and reading it from another location, thereby improving security.

[0030] Furthermore, the delivery person terminal 10 has a communication function that transmits various types of information to or receives from the unlocking control server 1. The information transmitted includes the property ID read from the two-dimensional code, identification information including the company ID that identifies the delivery company to which the delivery person belongs and the delivery person ID that identifies the delivery person, a call signal to call the delivery destination, delivery information regarding the delivery item for which contactless delivery is specified (room number, slip number, etc.), and a completion report to report the completion of delivery.

[0031] On the other hand, the information received by the delivery terminal 10 includes, as will be described later, a delivery list of all deliveries addressed to destinations within the apartment building, and command signals to activate the unlock button. The delivery terminal 10 also has a display function that shows this delivery list, the unlock button, etc. Furthermore, the delivery terminal 10 has a communication function that allows it to establish voice calls, video calls, or text calls with the resident terminal 11 via the unlock control server 1.

[0032] [2] Resident terminal 11 As shown in Figure 1, the resident terminal 11 is a terminal used by residents who are the recipients of deliveries within the apartment building, and is composed of a computer such as a smartphone or tablet. In this embodiment, a program for resident terminals is installed on the resident terminal 11. The resident terminal 11 then executes the resident terminal program, thereby performing the functions described later.

[0033] Specifically, when the resident terminal 11 receives a call notification from the unlocking control server 1, it displays a call notification screen and notifies the resident by sound and vibration. When the resident operates the response button displayed on the call notification screen, a call is established between the resident terminal 11 and the delivery person terminal 10 via the unlocking control server 1. Subsequently, when the resident operates the unlock button displayed on the call notification screen, an unlock permission message is sent to the unlocking control server 1, authorizing the unlocking of the locking mechanism 13.

[0034] Furthermore, when a resident enters the building, the resident terminal 11 reads the property ID from a two-dimensional code located near the entrance door and transmits registration information, including the property ID and the resident ID that identifies the resident, to the unlocking control server 1. As a result, if the registration information is verified by the unlocking control server 1, the locking mechanism 13 is unlocked and entry is permitted.

[0035] [3] Unlocking signal output device 12 As shown in Figures 1 and 2, the unlocking signal output device 12 is a device that outputs an unlocking signal to the locking mechanism 13 in response to an unlocking instruction received from the unlocking control server 1. In this embodiment, the unlocking signal output device 12 is configured as a contact output device and outputs a voltage-free contact signal as an unlocking signal to the locking mechanism 13 installed in the entrance door of an apartment building or the like. The unlocking signal output device 12 may be configured to output an unlocking signal in parallel with the unlocking output of the existing intercom equipment, and the unlocking control system 100 may coexist with the existing intercom equipment.

[0036] [4] Locking mechanism 13 The locking mechanism 13 is installed in the entrance door of an apartment building, etc., and is a device that electrically controls locking and unlocking. In this embodiment, the locking mechanism 13 is composed of an electric lock control panel, and as shown in Figures 1 and 2, when it receives a voltage-free contact signal (unlocking signal) from the unlocking signal output device 12, it unlocks the entrance door. Furthermore, it is designed to automatically lock the entrance door after it has been opened and closed.

[0037] The locking mechanism 13 is not limited to an electric lock control panel, but may also be a smart lock that can be retrofitted to an existing entrance door, etc. In this case, the unlocking signal output device 12 can also transmit the unlocking signal via a wireless communication protocol such as Bluetooth® or Wi-Fi®.

[0038] [5] Unlock control server 1 The unlocking control server 1 is composed of computers such as cloud servers or physical servers, and controls the unlocking of the locking mechanism 13 in the multi-unit building. In this embodiment, as shown in Figure 2, the unlocking control server 1 mainly has a communication means 2, a storage means 3, and a processing means 4. Each of these components will be described below.

[0039] Communication means 2 implements communication functions in the unlocking control server 1. In this embodiment, communication means 2 is composed of a wireless module compatible with carrier network standards such as 5G and wireless LAN standards such as Wi-Fi (registered trademark). Communication means 2 transmits and receives various data between the delivery person terminal 10, the responder terminal 11, the delivery company server (not shown), the unlocking signal output device 12, etc., via a communication network such as the Internet.

[0040] The storage means 3 stores various types of data and also functions as a working area when the arithmetic processing means 4 performs arithmetic processing. In this embodiment, the storage means 3 is composed of a solid-state drive (SSD), a hard disk drive (HDD), ROM (Read Only Memory), RAM (Random Access Memory), flash memory, etc., and as shown in Figure 2, it has a program storage unit 31, an identification information storage unit 32, a delivery list storage unit 33, a log information storage unit 34, a registration information storage unit 35, and a visitor site storage unit 36.

[0041] The unlocking control program 1a of this embodiment is installed in the program storage unit 31. The arithmetic processing means 4 then executes the unlocking control program 1a, causing the computer acting as the unlocking control server 1 to function as one of the functional units described later.

[0042] The usage of the unlocking control program 1a is not limited to the above configuration. For example, the unlocking control program 1a may be stored on a non-temporary storage medium that can be read by a computer, such as an SD card, CF card, USB memory, external HDD (Hard Disk Drive), external SSD (Solid State Drive), CD-ROM, DVD-ROM, etc., and then read and executed directly from the storage medium.

[0043] The identification information storage unit 32 stores identification information for identifying the apartment building and the delivery person. In this embodiment, the identification information pre-stored includes a property ID for identifying the apartment building being managed, a company ID for identifying the delivery company to which the delivery person belongs, and a delivery person ID for identifying the delivery person. The property ID is used to obtain the delivery list, and the company ID and delivery person ID are used to authenticate the delivery person.

[0044] The delivery list storage unit 33 stores a delivery list for all deliveries addressed to destinations within the building complex. In this embodiment, the unlocking control server 1 manages the period from when the delivery person enters the building complex until all deliveries are completed as a single delivery session, and prepares a delivery list for each delivery session. In this embodiment, the delivery list includes information such as the destination ID (room number, etc.), recipient name, slip number, name of the delivered item, delivery type (e.g., regular / refrigerated), delivery option (e.g., in person / leave at door), and delivery status (e.g., not called / absent / delivered).

[0045] The log information storage unit 34 stores log information related to deliveries. In this embodiment, the log information recorded includes unlocking events (unlocking date and time, type of unlocker, unlocker ID, unlocking result, etc.), call events (call date and time, caller, recipient, call duration, etc.), delivery events (delivery completion date and time, delivery destination, slip number, delivery photo, etc.), and audio and video data of visitors. This log information is used for verification by residents, audits by administrators, and troubleshooting in the event of a problem.

[0046] The registration information storage unit 35 stores registration information about residents of a multi-unit building. In this embodiment, the registration information includes a resident ID (room number, etc.) that identifies the resident, the resident's name, and the contact information and forwarding destination (telephone number, email address, etc.) of the resident terminal 11, all of which are associated with the property ID. If there are multiple residents at a single delivery address, the registration information for all residents is linked and registered.

[0047] The visitor site storage unit 36 ​​stores a visitor site (web page data) for visitors to call residents within the building. In this embodiment, the visitor site displays a form for inputting and selecting information to identify the destination (name, room number, etc.), as well as a call button. In this embodiment, the URL of the visitor site is embedded in a two-dimensional code provided near the locking mechanism 13. Therefore, visitors can easily obtain the URL and access the visitor site simply by reading the two-dimensional code with a visitor terminal (not shown).

[0048] The visitor terminal, like the delivery person terminal 10 and the resident terminal 11, consists of a smartphone or tablet. However, the visitor terminal does not need to have a program specifically for the unlocking control system 100 installed; it only needs to have a web browser that can access the visitor site installed. In addition, for visitors who do not have a visitor terminal, a guest terminal (not shown) with the visitor site pre-displayed may be permanently installed near the entrance door.

[0049] The arithmetic processing unit 4 is composed of a CPU (Central Processing Unit) and the like, and by executing the unlocking control program 1a installed in the program storage unit 31, it functions as shown in Figure 2: an identification information acquisition unit 41, an identification information determination unit 42, a delivery list acquisition unit 43, a delivery list transmission unit 44, a call signal acquisition unit 45, a call notification transmission unit 46, a call response acquisition unit 47, a call establishment unit 48, an unlocking permission acquisition unit 49, an unlocking instruction transmission unit 50, a delivery completion notification unit 51, an absence processing unit 52, a delivery information acquisition unit 53, a delivery information determination unit 54, an unlock button activation unit 55, a registration information acquisition unit 56, a registration information determination unit 57, and a visitor site transmission unit 58. Each component will be described in more detail below.

[0050] The identification information acquisition unit 41 is a functional unit that acquires identification information from the delivery person terminal 10. In this embodiment, when a delivery person is about to deliver to a destination within a multi-unit building, the delivery person terminal 10 reads a two-dimensional code provided near the entrance door to acquire the property ID of the multi-unit building. The delivery person terminal 10 then transmits the property ID, along with the contractor ID and the delivery person ID, as identification information to the unlock control server 1. Therefore, the identification information acquisition unit 41 acquires the identification information (property ID, contractor ID, and delivery person ID) via the communication means 2.

[0051] The identification information determination unit 42 is a functional unit that determines whether the identification information transmitted from the delivery person terminal 10 is legitimate information. In this embodiment, the identification information determination unit 42 compares the identification information acquired by the identification information acquisition unit 41 with the legitimate identification information stored in the identification information storage unit 32. If the two match, it determines that the identification information transmitted from the delivery person terminal 10 is legitimate information and permits subsequent processing. On the other hand, if the comparison fails, it determines that the identification information transmitted from the delivery person terminal 10 is not legitimate information and notifies the delivery person terminal 10 of this fact and displays it.

[0052] The delivery list acquisition unit 43 is a functional unit that acquires a delivery list for a multi-unit building that is subject to delivery. In this embodiment, the delivery list acquisition unit 43 identifies a delivery company based on the company ID acquired by the identification information acquisition unit 41. Then, it accesses the delivery company server of the identified delivery company via an API (Application Programming Interface) and acquires a delivery list for the multi-unit building corresponding to the property ID acquired by the identification information acquisition unit 41. The acquired delivery list is stored in the delivery list storage unit 33.

[0053] The delivery list transmission unit 44 is a functional unit that transmits the delivery list to the delivery person terminal 10. In this embodiment, the delivery list transmission unit 44 transmits the delivery list acquired by the delivery list acquisition unit 43 to the delivery person terminal 10, which has been authenticated by the identification information determination unit 42, via the communication means 2. As a result, the display screen of the delivery person terminal 10 shows a list of all deliveries to be made in the building on that day.

[0054] The call signal acquisition unit 45 is a functional unit that acquires a call signal from the delivery person terminal 10 to call the delivery destination. In this embodiment, when a delivery person selects the delivery destination they want to call from the delivery list displayed on the delivery person terminal 10 and operates the call button, a call signal including the delivery destination ID (room number, etc.) of that destination is sent to the unlock control server 1. Therefore, the call signal acquisition unit 45 acquires this call signal via the communication means 2.

[0055] The call notification transmission unit 46 is a functional unit that transmits a call notification to the resident terminal 11 to inform it that it is being called. In this embodiment, when the call signal acquisition unit 45 acquires a call signal, the call notification transmission unit 46 refers to the registration information storage unit 35 based on the delivery destination ID included in the call signal and identifies the contact information of the resident terminal 11. Then, it transmits a call notification to the resident terminal 11 via the communication means 2. If multiple resident terminals 11 are registered to a single delivery destination, the call notification is transmitted to all resident terminals 11 simultaneously.

[0056] The call response acquisition unit 47 is a functional unit that acquires call responses to call notifications from the resident terminal 11. In this embodiment, when the resident terminal 11 acquires a call notification from the unlocking control server 1, it displays a call notification screen and notifies the resident. When the resident performs a response operation on the call notification screen, the call response is sent to the unlocking control server 1. Therefore, the call response acquisition unit 47 acquires the call response via the communication means 2.

[0057] The call establishment unit 48 is a functional unit that establishes a call between the delivery person terminal 10 and the resident terminal 11. In this embodiment, if a call response is obtained by the call response acquisition unit 47, the call establishment unit 48 establishes a voice call, video call, or text call, etc., between the delivery person terminal 10 and the resident terminal 11. This allows the resident to confirm the matter through the call with the delivery person and decide whether or not to unlock the locking mechanism 13. On the other hand, if no call response is obtained, the call establishment unit 48 executes the absence processing described later without establishing a call between the two.

[0058] The unlocking permission acquisition unit 49 is a functional unit that acquires permission to unlock the locking mechanism 13 from the resident terminal 11. In this embodiment, when a resident operates the unlock button displayed on the display screen of the resident terminal 11 during or after a call with a delivery person, an unlocking permission that authorizes the unlocking of the locking mechanism 13 is transmitted to the unlocking control server 1. Therefore, the unlocking permission acquisition unit 49 acquires this unlocking permission via the communication means 2.

[0059] The unlocking instruction transmission unit 50 is a functional unit that outputs an unlocking instruction to the unlocking signal output device 12. In this embodiment, when the unlocking permission acquisition unit 49 obtains an unlocking permission, the unlocking instruction transmission unit 50 transmits an unlocking instruction to the unlocking signal output device 12 installed in the apartment building where the resident who sent the unlocking permission resides. When the unlocking signal output device 12 obtains the unlocking instruction, it outputs an unlocking signal to the locking mechanism 13.

[0060] Furthermore, when making deliveries within apartment buildings where elevator operation is restricted, such as luxury condominiums or luxury hotels, the unlock instruction transmission unit 50 transmits the destination floor information of the delivery location to the unlock signal output device 12 along with the unlock instruction. Meanwhile, the unlock signal output device 12 outputs a control signal to the elevator control panel to control the elevator's destination floor based on the acquired destination floor information. As a result, the delivery person can move freely in the elevator as long as the delivery destination is on that floor, thus improving delivery efficiency.

[0061] The delivery completion notification unit 51 is a functional unit that notifies the resident terminal 11 that the delivery has been completed. In this embodiment, when the delivery person completes the delivery, a completion report including the room number of the delivery destination, the date and time of delivery completion, a photo of the delivered item (in the case of contactless delivery), and a message from the delivery person is sent from the delivery person terminal 10. Therefore, when the delivery completion notification unit 51 receives the completion report from the delivery person terminal 10, it notifies the resident terminal 11 of the delivery destination that the delivery has been completed. The completion report is also stored in the log information storage unit 34 and made available for viewing by the resident, etc.

[0062] The Absence Processing Unit 52 is a functional unit that performs processing when the resident is absent. In this embodiment, the Absence Processing Unit 52 performs absence processing if the Call Response Acquisition Unit 47 does not acquire a call response even after a predetermined time (e.g., 30 seconds) has elapsed since the Call Notification Transmission Unit 46 sent a call notification. Specifically, the Absence Processing Unit 52 refers to the resident's registration information stored in the Registration Information Storage Unit 35 and, if a forwarding destination (family member living together, building manager, etc.) is set, automatically forwards the call notification to that forwarding destination.

[0063] After automatic transfer, if there is a response from the transfer destination, the call establishment unit 48 establishes a call between the delivery person's terminal 10 and the resident's terminal 11 at the transfer destination. On the other hand, if there is no response from the transfer destination, the absence processing unit 52 saves the date and time of the delivery visit, as well as the delivery person's voice and video data, etc., to the log information storage unit 34.

[0064] The delivery information acquisition unit 53 is a functional unit that acquires delivery information for deliveries designated for unattended delivery. In this embodiment, if the recipient is absent, the delivery person sets the delivery status of that recipient to "absent" in the delivery list. Once calls to all delivery destinations within the building have been completed, the system displays a list of absent delivery destinations and selects all delivery destinations for deliveries designated for unattended delivery in the delivery options. In this state, when the delivery person operates the unattended delivery button displayed on the delivery person terminal 10, the delivery person terminal 10 transmits delivery information (such as the slip number) for deliveries designated for unattended delivery. Therefore, the delivery information acquisition unit 53 acquires this delivery information via the communication means 2.

[0065] The delivery information determination unit 54 is a functional unit that determines whether the delivery information transmitted from the delivery person terminal 10 is correct or not. In this embodiment, the delivery information determination unit 54 compares the delivery information acquired by the delivery information acquisition unit 53 with various information stored in the delivery list storage unit 33. If the two match, it determines that the delivery information transmitted from the delivery person terminal 10 is correct and permits subsequent processing. On the other hand, if the comparison fails, it determines that the delivery information transmitted from the delivery person terminal 10 is incorrect and notifies and displays to the delivery person terminal 10 that it cannot be unlocked.

[0066] The unlock button activation unit 55 is a functional unit in the delivery person terminal 10 that activates the unlock button for sending an unlock permission. In this embodiment, when the delivery information determination unit 54 determines that the delivery information is correct, the unlock button activation unit 55 transmits a signal to the delivery person terminal 10 to activate the unlock button. As a result, the unlock button is displayed or activated on the display screen of the delivery person terminal 10.

[0067] With this configuration, when a delivery person operates the unlock button displayed on the delivery person terminal 10, the unlock permission acquisition unit 49 obtains unlock permission from the delivery person terminal 10. Once unlock permission is obtained, the unlock instruction transmission unit 50 sends an unlock instruction to the unlock signal output device 12. Upon receiving the unlock instruction, the unlock signal output device 12 outputs an unlock signal to the locking mechanism 13, causing it to unlock. As a result, even if the resident is absent, the delivery person can unlock the locking mechanism 13 by operating the delivery person terminal 10 and leave the package at the door.

[0068] The registration information acquisition unit 56 is a functional unit that acquires registration information from the resident terminal 11 when a resident enters the apartment building. In this embodiment, when a resident enters the apartment building, the resident terminal 11 reads a two-dimensional code provided near the entrance door to obtain the property ID of the apartment building. The resident terminal 11 then transmits the registration information, including the property ID and resident ID, to the unlock control server 1. Therefore, the registration information acquisition unit 56 acquires the registration information via the communication means 2.

[0069] The registration information determination unit 57 is a functional unit that determines whether the registration information transmitted from the resident terminal 11 is legitimate information. In this embodiment, the registration information determination unit 57 compares the registration information acquired by the registration information acquisition unit 56 with the legitimate registration information stored in the registration information storage unit 35. If the two match, it determines that the registration information transmitted from the resident terminal 11 is legitimate information and causes the unlock instruction transmission unit 50 to send an unlock instruction. On the other hand, if the comparison fails, it determines that the registration information transmitted from the resident terminal 11 is not legitimate information and notifies the resident terminal 11 of this fact and displays it.

[0070] The visitor site transmission unit 58 is a functional unit that transmits a visitor site to a visitor terminal for the visitor to call a resident within the building complex. In this embodiment, when a visitor calls a resident within the building complex, the visitor terminal reads a two-dimensional code for visitors provided near the entrance door and obtains the URL of the visitor site. The visitor terminal then uses this URL to request access to the visitor site from the unlocking control server 1. To this end, the visitor site transmission unit 58 transmits the visitor site stored in the visitor site storage unit 36 ​​to the visitor terminal that made the access request via the communication means 2.

[0071] When a visitor selects or enters their destination on the visitor site displayed on their visitor terminal and operates the call button, a call signal to that destination is sent to the unlock control server 1. Therefore, the call signal acquisition unit 45 can also acquire a call signal from the visitor terminal to call the destination via the visitor site.

[0072] In this case, the call notification transmission unit 46 sends a call notification to the resident terminal 11 at the destination in response to the call signal. Then, when the call establishment unit 48 receives a call response from the resident terminal 11 in response to the call notification, it establishes a call between the visitor terminal and the resident terminal 11. Subsequently, when the unlock permission acquisition unit 49 obtains unlock permission from the resident terminal 11, the unlock instruction transmission unit 50 sends an unlock instruction to the unlock signal output device 12. This makes it possible to control the unlocking of the locking mechanism 13 for visitors in the same way as for delivery personnel.

[0073] Next, the operation of the unlocking control server 1, unlocking control system 100, unlocking control program 1a, and unlocking control method of this embodiment will be explained using the flowcharts in Figures 3 to 9.

[0074] (1) When the delivery person enters the building This section describes the unlocking control process when a delivery person enters a multi-unit building. As shown in Figures 1 and 3, when a delivery person arrives at the entrance of the multi-unit building, they activate a program for their delivery terminal and read a two-dimensional code located near the locking mechanism 13 (step S1). This allows the delivery terminal 10 to easily obtain the property ID of the multi-unit building to be delivered. If a dynamic two-dimensional code with a set validity period is used, misuse is prevented and security is improved.

[0075] Next, the delivery terminal 10 sends the property ID acquired in step S1, along with the contractor ID and delivery person ID set in the delivery terminal program, as identification information to the unlock control server 1 (step S2), at which point the identification information acquisition unit 41 acquires the identification information (step S3: identification information acquisition step). Then, the identification information determination unit 42 checks whether the identification information acquired in step S3 matches the legitimate identification information (step S4: identification information determination step).

[0076] If the verification results in incorrect identification information (Step S4: NO), a message to that effect is displayed on the delivery person terminal 10 (Step S5), and the process is terminated. This prevents delivery persons without correct identification information from entering the building, thus providing a high level of security. On the other hand, if the identification information is correct (Step S4: YES), the delivery list acquisition unit 43 acquires the delivery list from the delivery company server (Step S6: Delivery List Acquisition Step), and the delivery list transmission unit 44 transmits the delivery list acquired in Step S6 to the delivery person terminal 10 (Step S7: Delivery List Transmission Step). This ensures that the delivery list is provided only to legitimate delivery persons belonging to registered legitimate delivery companies, thus guaranteeing a high level of security.

[0077] When the delivery person terminal 10 displays the delivery list obtained from the unlocking control server 1 (step S8), the delivery person selects a delivery destination from the delivery list and performs a call operation (step S9). This sends a call signal from the delivery person terminal 10 to the unlocking control server 1. Meanwhile, when the unlocking control server 1's call signal acquisition unit 45 acquires the call signal (step S10: call signal acquisition step), the call notification transmission unit 46 sends a call notification to the resident terminal 11 of the delivery destination specified by the call signal (step S11: call notification transmission step).

[0078] When the resident terminal 11 receives a call notification (step S12), it notifies the resident. Then, when the resident performs a response operation to the call notification (step S13), a call response is sent to the unlocking control server 1. If the unlocking control server 1's call response acquisition unit 47 receives a call response from the resident terminal 11 (step S14: YES), it proceeds to the resident at home flow (from "A" onwards in Figure 4). On the other hand, if there is no call response (step S14: NO), it proceeds to the absent flow (from "B" onwards in Figure 5).

[0079] (1-1) Workflow for when working from home When the unlocking control server 1 receives a call response from the resident terminal 11 (step S14: YES), as shown in Figure 4, the call establishment unit 48 establishes a call between the delivery person terminal 10 and the resident terminal 11 (step S21: call establishment step). This allows the resident to communicate with the delivery person and decide whether or not to unlock the locking mechanism 13.

[0080] After a conversation with the delivery person, if the resident performs an operation on the resident terminal 11 to authorize the unlocking of the locking mechanism 13 (step S22: YES), the unlocking permission acquisition unit 49 obtains unlocking permission from the resident terminal 11 (step S23: unlocking permission acquisition step). On the other hand, if the resident does not authorize unlocking (step S22: NO), unlocking permission is not sent to the unlocking control server 1, and this process ends. As a result, entry of delivery persons not authorized by the resident is prohibited, thus providing a high level of security.

[0081] Upon obtaining permission to unlock, the unlocking control server 1 sends an unlocking instruction transmission unit 50 to the unlocking signal output device 12 (step S24: unlocking instruction transmission step). When the unlocking signal output device 12 receives the unlocking instruction from the unlocking control server 1 (step S25), it outputs an unlocking signal to the locking mechanism 13 (step S26). When the locking mechanism 13 receives the unlocking signal from the unlocking signal output device 12 (step S27), it unlocks the entrance door, etc. (step S28). As a result, delivery personnel and residents can control the process from calling to communication and unlocking simply by having their own terminals ready, without using an intercom system.

[0082] When the locking mechanism 13 is unlocked, the delivery person enters the building and completes the delivery to the destination. After the delivery is completed, the delivery person sends a completion report from the delivery person terminal 10 to the unlocking control server 1 (step S29). The delivery completion notification unit 51 saves the completion report to the log information storage unit 34 (step S31) and notifies the resident terminal 11 of the delivery completion (step S30). The resident terminal 11 receives the delivery completion notification (step S32). This completes the series of delivery processes for one delivery destination.

[0083] Subsequently, the delivery person determines whether all deliveries on the delivery list have been completed (step S33). If all deliveries are completed (step S33: YES), the process ends. On the other hand, if there are any incomplete deliveries (step S33: NO), the process returns to step S9 from "C" in Figure 3, and the above process (steps S9 to S33) is repeated for the next delivery destination.

[0084] In this system, delivery personnel can use a delivery list to continuously call up the next delivery destination from anywhere within the building using the delivery terminal 10. Therefore, delivery personnel do not need to return to the entrance after completing each delivery, optimizing movement within the building. This reduces the physical burden and delivery time for delivery personnel working within the building, improving delivery efficiency. Furthermore, the increased number of deliveries per unit of time for each delivery person provides significant benefits to the delivery company.

[0085] Furthermore, in this embodiment, by using a delivery list, the entire process from when the delivery person enters the building until all deliveries are completed is managed as a single delivery session. As a result, the delivery status for each destination is centrally managed, allowing the delivery person to accurately understand the delivery status for each destination, thus speeding up the delivery process and preventing delivery errors.

[0086] (1-2) Flow when absent If there is no response from the resident terminal 11 (step S14: NO), as shown in Figure 5, after a predetermined time has elapsed (step S41: YES), the absence processing unit 52 executes absence processing (step S42). Specifically, as shown in Figure 6, the call notification from the delivery person is automatically forwarded to the forwarding destination (step S101), and if there is a response from the forwarding destination (step S102: YES), the process proceeds from "A" in Figure 4 to step S21. This increases the response rate to calls from delivery people, thus reducing the effort required for redelivery, etc. On the other hand, if there is no response from the forwarding destination either (step S102: NO), the delivery date and time, video data, etc. are saved in the log information storage unit 34 (step S103).

[0087] The delivery person sets the delivery status of unanswered delivery destinations to "Absent" in the delivery list (step S43). If calls have not been completed for all delivery destinations within the building (step S44: NO), the process returns to step S9 from "C" in Figure 3, and the above process (steps S9 to S33) is repeated for the next delivery destination. At this time, the delivery person can call the next delivery destination continuously from the delivery list, thus improving delivery efficiency.

[0088] On the other hand, once calls to all delivery destinations within the building have been completed (Step S44: YES), the delivery person terminal 10 displays a list of undelivered destinations. If there are no deliveries for which "leave at door" is specified in the delivery options (Step S45: NO), this process ends. On the other hand, if there are deliveries for which "leave at door" is specified, all delivery destinations for those deliveries are selected (Step S46). In this state, when the delivery person requests "leave at door" from the delivery person terminal 10, delivery information regarding the deliveries for which "leave at door" is specified is sent to the unlock control server 1 (Step S47).

[0089] In the unlocking control server 1, when the delivery information acquisition unit 53 acquires delivery information from the delivery person terminal 10 (step S48), the delivery information determination unit 54 determines whether the delivery information is correct or not (step S49). If the result of this determination is that the delivery information is incorrect (step S49: NO), the delivery person terminal 10 displays a message to that effect (step S50), and the process ends. This prevents delivery persons without correct delivery information from entering the building, thus providing a high level of security.

[0090] On the other hand, if the delivery information is correct (step S49: YES), the unlock button activation unit 55 activates the unlock button on the delivery person terminal 10 (step S51). As a result, the activated unlock button is displayed on the delivery person terminal 10 (step S52), and when the delivery person operates this unlock button (step S53), an unlock permission is sent to the unlock control server 1.

[0091] Upon receiving the unlocking permission, the unlocking control server 1 returns from "D" in Figure 4 to step S23 and executes the above-described process (steps S23 to S28), thereby unlocking the locking mechanism 13. This allows the delivery person to unlock the locking mechanism 13 from the delivery person terminal 10 and leave the package unattended, even if the recipient is absent. As a result, the delivery person does not need to return to the entrance multiple times for unattended delivery, optimizing movement within the building, reducing the physical burden on the delivery person and delivery time, and improving delivery efficiency.

[0092] (1-3) Elevator control Next, we will explain the process for deliveries made within a multi-unit building where elevator operation is restricted, using Figure 7. Note that the flowchart in Figure 7 omits the descriptions of steps S1 to S22 described above. Also, in the flowchart in Figure 7, processes that are the same as or equivalent to those described above are given the same step number and colored, and further explanation is omitted.

[0093] After the processes described in steps S1 to S22 above, when the unlocking permission acquisition unit 49 obtains unlocking permission from the resident terminal 11 (step S23), the unlocking instruction transmission unit 50 transmits the unlocking instruction along with the destination floor information of the delivery destination to the unlocking signal output device 12 (step S61). When the unlocking signal output device 12 obtains the unlocking instruction and destination floor information from the unlocking control server 1 (step S62), it outputs an unlocking signal to the locking mechanism 13 (step S26) and outputs an elevator control signal to the elevator control panel (step S63).

[0094] As a result, the locking mechanism 13, having received the unlocking signal, receives an unlocking signal from the unlocking signal output device 12 (step S27) as described above, and unlocks the entrance door, etc. (step S28). Meanwhile, the elevator control panel, having received the control signal, executes a call control to the destination floor permitted by the control signal (step S64). This allows delivery personnel to move freely by elevator to any floor where the delivery destination is located, even in apartment buildings where elevator operation is restricted, thereby improving delivery efficiency. The above elevator control can also be applied to cases where residents or visitors enter an apartment building, as will be described later.

[0095] (2) When a resident enters a multi-unit building Next, the unlocking control process when a resident enters the building will be explained using Figure 8. In the flowchart of Figure 8, processes that are the same as or equivalent to those described above are given the same step number and colored, and further explanation is omitted.

[0096] As shown in Figure 8, when a resident arrives at the entrance of the apartment building, they activate a program for the resident's terminal and read a two-dimensional code located near the locking mechanism 13 (step S71). This allows the resident's terminal 11 to easily obtain the property ID of the apartment building in which the resident resides. If a dynamic two-dimensional code with a set validity period is used at this time, misuse is prevented and security is improved.

[0097] Next, the resident terminal 11 sends the resident ID, which was set in the resident terminal program in addition to the property ID obtained in step S71, to the unlock control server 1 as registration information (step S72), and the registration information acquisition unit 56 acquires the registration information (step S73: registration information acquisition step). Then, the registration information determination unit 57 checks whether the identification information obtained in step S73 matches the legitimate identification information (step S74: registration information determination step).

[0098] If the verification results in incorrect registration information (step S74: NO), a message to that effect is displayed on the resident terminal 11 (step S5), and the process is terminated. This prevents residents without correct registration information from entering the building, thus providing a high level of security. On the other hand, if the registration information is correct (step S74: YES), the unlocking instruction transmission unit 50 sends an unlocking instruction to the unlocking signal output device 12 (step S24), and the locking mechanism 13 is unlocked after subsequent processing (steps S25 to S28). This allows residents to control the unlocking of the locking mechanism 13 and enter the building simply by having the resident terminal 11 ready, without using the intercom system or involving other intermediaries.

[0099] (3) When a visitor enters a multi-purpose building Next, the unlocking control process when a visitor enters a multi-unit building will be explained using Figure 9. In the flowchart of Figure 9, processes that are the same as or equivalent to those described above are given the same step number and colored, and further explanation is omitted.

[0100] As shown in Figure 9, when a visitor arrives at the entrance of the building, they use a visitor terminal to read a two-dimensional code located near the locking mechanism 13 (step S81). This allows the visitor terminal to easily obtain the URL of the visitor site. If a dynamic two-dimensional code with a set validity period is used, misuse is prevented and security is improved.

[0101] Next, the visitor terminal uses the URL obtained in step S81 to request access to the visitor site from the unlock control server 1 (step S82). As a result, the visitor site transmission unit 58 transmits the visitor site to the visitor terminal (step S83: visitor site transmission step), and the visitor site is displayed on the visitor terminal (step S84).

[0102] When a visitor selects their destination on the visitor site and performs a call operation, a call signal is sent from the visitor terminal to the unlocking control server 1 (step S85). After the above-described process (steps S10 to S28), the locking mechanism 13 is unlocked if the resident gives permission. This allows visitors to control the unlocking of the locking mechanism 13 and enter the building simply by having a visitor terminal, without using an intercom system. Alternatively, if a guest terminal is installed in the entrance of the building beforehand, a visitor terminal may not be necessary.

[0103] According to this embodiment, the following effects are achieved. 1. Without using an intercom system, this inexpensive configuration allows for the release of the locking mechanism 13 in apartment buildings, while also reducing the physical burden on delivery personnel and delivery time, thereby improving delivery efficiency. 2. Delivery personnel can call delivery destinations on the delivery list in any order from any point within the building. 3. In addition to face-to-face delivery initiated by the resident unlocking the door, contactless delivery initiated by the delivery person can be performed consecutively within the same delivery session. 4. Even in apartment buildings where elevator operation is restricted, delivery personnel can freely move to the floor where the delivery destination is located, improving delivery efficiency. 5. Residents can unlock the locking mechanism 13 using the resident terminal 11 and enter the building without using the intercom system or being assisted by another person. 6. Visitors can communicate with residents using a visitor terminal or guest terminal without using the intercom system, and have the locking mechanism 13 unlocked. 7. The QR code allows for easy acquisition of property IDs and URLs for visitor websites. 8. Dynamic QR codes can prevent the misuse of property IDs and visitor site URLs, thereby improving security.

[0104] Furthermore, the unlocking control server 1, unlocking control system 100, unlocking control program 1a, and unlocking control method according to the present invention are not limited to the embodiments described above and can be modified as appropriate.

[0105] For example, in the embodiment described above, the unlocking control system 100 was applied to an apartment building without an intercom system, but the configuration is not limited to this, and the unlocking control system 100 may also be applied to and used in combination with an existing apartment building that has an intercom system.
