Description

[Technical Field]

[0001] The present invention relates to a locking mechanism unit provided in a facility and a management system for managing the locking and unlocking of the locking mechanism unit. [Background technology]

[0002] In some accommodation facilities, for security purposes, the doors of guest rooms provided to guests are equipped with, for example, electronic locks.

[0003] A locking and unlocking control system that controls the locking and unlocking key code for opening and closing this electronic lock is known (see Patent Document 1). This system allows communication between a user terminal used by a user who requests to open or close a lock, a locking and unlocking control server, and a housing management server of an apartment building where a locking and unlocking device is installed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6712365 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in apartment buildings where the above-mentioned locking / unlocking control system is used, the locking / unlocking devices are usually different for each apartment building, and the means for opening and closing the locking / unlocking devices are different, which makes it necessary to create different processing programs for each type of locking mechanism in the locking / unlocking control system, which is cumbersome.

[0006] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a management system, management method, and management program that can centrally manage password restriction information, which is a restriction that is a characteristic inherent to the lock mechanism unit, even if it is different, by sending usage information, which is the key opening and closing means, to the user in URL format via the terminal. [Means for solving the problem]

[0007] The management system of the present invention comprises: a system control unit that obtains password constraint information, which is a restriction specific to a locking mechanism unit, from a lock table based on a locking mechanism ID for identifying the locking mechanism unit sent from a terminal; generates or obtains a password for locking and unlocking the locking mechanism unit using the password constraint information and the usage time sent from the terminal; and sets the password, a password display type indicating the display format of the password, and the usage time in a password management table; a URL processing unit that generates a URL for connecting to a display processing unit for a usage ID for identifying the combination of the locking mechanism ID and the usage time and sets the URL in the password management table; and a system memory unit that has the lock table in which the locking mechanism ID and the password constraint information are stored, and the password management table in which the usage ID, the locking mechanism ID, the usage time, the password, the password display type, and the URL are stored.When a connection is made from the terminal based on the URL, the display processing unit obtains the password, the password display type, and the usage time from the password management table based on the URL, and generates usage information that enables the obtained password to be displayed.

[0008] In the management system, the usage ID is set by the terminal and transmitted to the management system, or the system control unit sets the usage ID for the lock mechanism ID and usage time transmitted from the terminal.

[0009] In the management system, the lock mechanism is unlocked using the usage information.

[0010] In the management system, if the terminal is a user terminal, the password is displayed in text on the display screen of the user terminal, and the locking mechanism is unlocked using the password.

[0011] In the management system, if the terminal is a user terminal, a two-dimensional code corresponding to the password is displayed on the display screen of the user terminal, and the locking mechanism is unlocked using the two-dimensional code.

[0012] The management method of the present invention includes a lock table storing a lock mechanism ID for identifying a lock mechanism unit sent from a terminal and password constraint information which is a restriction specific to the lock mechanism unit, and a password management table storing the lock mechanism ID, the usage time sent from the terminal, a usage ID for identifying the combination of the lock mechanism ID and the usage time, a password for locking and unlocking the lock mechanism unit, a password display type indicating the display format of the password, and a URL for connecting to a display processing unit, and includes the steps of: acquiring the password constraint information from the lock table based on the lock mechanism ID sent from the terminal, generating or acquiring the password using the password constraint information and the usage time, and setting the password, the password display type, and the usage time in the password management table; generating the URL for the usage ID and setting the URL in the password management table; when a connection based on the URL is made from the terminal, acquiring the password, the password display type, and the usage time from the password management table based on the URL; and generating usage information which enables the acquired password to be displayed.

[0013] The management program of the present invention stores in a lock table a lock mechanism ID for identifying a lock mechanism unit sent from a terminal and password constraint information which is a restriction specific to the lock mechanism unit, and in a password management table stores the lock mechanism ID, the usage time sent from the terminal, a usage ID for identifying the combination of the lock mechanism ID and the usage time, a password for locking and unlocking the lock mechanism unit, a password display type which indicates the display format of the password, and a URL for connecting to a display processing unit.The management program causes a computer to execute the following steps: acquire the password constraint information from the lock table based on the lock mechanism ID sent from the terminal; generate or acquire the password using the password constraint information and the usage time; set the password, the password display type, and the usage time in the password management table; generate the URL for the usage ID and set the URL in the password management table; when a connection is made from the terminal based on the URL, acquire the password, the password display type, and the usage time from the password management table based on the URL; and generate usage information which enables the acquired password to be displayed. [Effects of the Invention]

[0014] In the management system, by sending usage information, which is the locking means, to users via their terminals in URL format, it is possible to centrally manage password restriction information, which is a restriction inherent to the locking mechanism, even when it differs. Furthermore, management can be performed using the same processing program regardless of the type of locking mechanism. Furthermore, by sending usage information in URL format, even if the locking mechanism ID, usage time, password, etc. are changed after a facility reservation, there is no need to notify the user of the above-mentioned changed information again. This reduces the burden on users and simplifies terminal processing, allowing the system to be operated. [Brief explanation of the drawings]

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an explanatory diagram of a system 10 according to an embodiment of the present invention, Fig. 2A is an explanatory diagram of a management system 50, Fig. 2B is an explanatory diagram of a lock table 60, Fig. 2C is an explanatory diagram of a password management table 62, Fig. 3A is an explanatory diagram of a lock mechanism unit 70, Fig. 3B is an explanatory diagram of a lock table 78, Fig. 4A is an explanatory diagram of a business terminal 20, Fig. 4B is an explanatory diagram of a terminal table 24 before receiving a URL, and Fig. 4C is an explanatory diagram of a terminal table 24 after receiving a URL.

[0017] <System 10 configuration explanation> The system 10 comprises a business terminal 20, a management system 50, a locking mechanism unit 70, and a user terminal 90. The business terminal 20 and the management system 50, the business terminal 20 and the user terminal 90, and the management system 50 and the locking mechanism unit 70 can communicate with each other via a public line 30 such as the Internet. The user terminal 90 can also communicate with the locking mechanism unit 70. The locking mechanism unit 70 is provided on a door 42 of a facility 40. The facility 40 is, for example, an accommodation facility, an apartment building, or the like.

[0018] The business terminal 20 is a business terminal having a communication function. For example, it is configured as a computer having a communication function such as a server. The business terminal 20 has a terminal storage unit 22, and the terminal storage unit 22 has a terminal table 24.

[0019] The management system 50 includes a system control unit 52, a URL processing unit 54, a display processing unit 56, a system storage unit 58, and a system communication unit 64, which are interconnected via a bus 66. The system control unit 52 includes a CPU, ROM, and RAM, and is a control unit that controls the entire management system 50.

[0020] The system control unit 52 is a means for obtaining password restriction information from the lock table 60 described later based on the lock mechanism ID, generating or obtaining a password using the password restriction information and the usage time sent from the business terminal 20, and setting the password, password display type, and usage time in the password management table 62 described later.

[0021] Here, the locking mechanism ID refers to an identification code sent from the business terminal 20 to identify the locking mechanism unit 70. The password refers to an identification code for locking and unlocking the locking mechanism unit 70. The password display type refers to the display format of the password. Specifically, if the password is displayed as text, the password display type is "text," and if the password is displayed as a two-dimensional code, the password display type is "two-dimensional code." If the password display type is displayed as text, the number of digits of the password can be specified. The usage time refers to the time during which the user uses the facility 40, and is set as the start time to end time of use of the facility 40. The password restriction information refers to information regarding restrictions that are unique characteristics of the locking mechanism unit 70 when issuing a password. Password restriction information includes the opening and closing methods that the lock mechanism unit 70 can handle, which are the basis for the password display type of the lock, such as a PIN, card key, two-dimensional code, or remote opening and closing / unlocking from the system; if the password is a PIN, the number of digits of the PIN; the identification code that makes up the PIN, such as a configuration format such as numbers only, a combination of numbers and specific symbols, etc.; the password setting method that specifies whether the means for setting the password is the management system 50 or the lock mechanism unit 70; and the date and time units that the lock mechanism unit 70 can set for the usage time, such as hours, days, etc.

[0022] The URL processing unit 54 is a means for generating a URL for connecting to the display processing unit 56, which will be described later, for the usage ID, and setting the URL in the password management table 62. Here, the usage ID refers to an identification code for identifying the combination of a locking mechanism ID and usage time. The usage ID may be set on the business terminal 20 and sent to the management system 50, or the business terminal 20 may send the locking mechanism ID and usage time to the management system 50, and the system control unit 52 may set the usage ID for the locking mechanism ID and usage time received.

[0023] The display processing unit 56 is a means for obtaining the password, password display type, and usage time from the password management table 62 based on the URL when a connection based on a URL is made from the business terminal 20, and generating usage information that enables the obtained password to be displayed. Here, the usage information includes the password, instruction information for unlocking the locking mechanism unit 70, etc.

[0024] The system storage unit 58 has a lock table 60 and a password management table 62. The lock table 60 stores lock mechanism IDs and password constraint information. In FIG. 2B, the lock table 60 stores the lock mechanism ID and password constraint information in that order, with Ra stored for La as the lock mechanism ID. Similarly, the lock table 60 stores Lb and Rb, and Lc and Rc.

[0025] The password management table 62 stores a usage ID, a locking mechanism ID, a usage time, a password, a password display type, and a URL. The password display type is generated based on the password constraint information. When the password is displayed as text on the display unit, the password display type is "text." If the number of digits is fixed, the number of digits is displayed. When the password is displayed as a two-dimensional code, the password display type is "two-dimensional code." The password display type refers to the display format of the password. Specifically, when the password is displayed as text, the password display type is "text." When the password is displayed as a two-dimensional code, the password display type is "two-dimensional code." Furthermore, when the password display type is displayed as text, the number of digits of the password can be specified. The usage time is the time during which the user uses the facility 40, and is set as the start time to the end time of use of the facility 40. For example, the password display type is set as T4 for the password constraint Ra, T9 for the password constraint Rb, and C for the password constraint Rc. Furthermore, the "T" in T4 and T9 indicates a display type, meaning a text display, and the number indicates the number of digits to be displayed, meaning 4 digits and 9 digits for T4 and T9, respectively. Furthermore, "C" indicates a display type, meaning a two-dimensional code display. In FIG. 2C, the password management table 62 stores a usage ID, a locking mechanism ID, a usage time, a password, a password display type, and a URL in this order. For the usage ID, Ia, La, Ua (start time 2024-01-01; 10:00, end time 2024-01-05; 10:00), Pa (1234), T4, and URLa are stored. Similarly, the password management table 62 stores Lb, Ub, Pb, T9, and URLb, and also stores Lc, Uc, Pc, C, and URLc. The system communication unit 64 is a means by which the management system 50 communicates with the business terminal 20 and the locking mechanism unit 70.

[0026] The lock mechanism unit 70 comprises a lock control unit 72, a lock / unlock unit 74, a lock memory unit 76, a lock input unit 80, and a lock communication unit 82, which are interconnected via a bus 84. The lock control unit 72 comprises a CPU, ROM, and RAM, and is a control unit that performs overall control of the lock mechanism unit 70. The lock / unlock unit 74 is a means for locking and unlocking the lock mechanism unit 70. The lock memory unit 76 has a lock table 78.

[0027] The lock table 78 stores the lock mechanism ID, usage time, and password. In FIG. 3B, the lock table 78 stores the lock mechanism ID, usage time, and password in that order, with Ua and Pa stored for the lock mechanism ID, La. The lock input unit 80 is an input means comprised of a keyboard, touch panel, etc. The lock communication unit 82 is a means by which the lock mechanism unit 70 communicates with the business terminal 20 and the management system 50.

[0028] The user terminal 90 is a user terminal with a communication function. For example, it may be a mobile phone, a smartphone, or a computer with a communication function. The user terminal 90 also has a user terminal display unit 92 for displaying a password, which will be described later.

[0029] <Explanation of System 10 operation> Next, the operation of the system 10 will be described with reference to Fig. 5. Fig. 5 is an explanatory diagram of the processing procedure of the system 10 according to an embodiment of the present invention. Figs. 6A to 6C are explanatory diagrams of usage information. Below, a case will be described in which user A operates the user terminal 90 to use the system 10 via the business terminal 20. Specifically, a case will be described in which user A uses a hotel room with a locking mechanism ID of La as the facility 40.

[0030] Here, it is assumed that when user A uses facility 40, the locking mechanism ID of the room that user A will use is registered in advance in business terminal 20. Specifically, it is assumed that business terminal 20 stores La as the locking mechanism ID in terminal table 24 (see FIG. 4B).

[0031] First, user A operates user terminal 90 and sends a password issuance request via business terminal 20 to management system 50, including a usage ID, locking mechanism ID, and desired usage time (step S1). Specifically, business terminal 20 obtains the usage ID, locking mechanism ID, and usage time from terminal table 24, and sends Ia as the usage ID, La as the mechanism ID, and Ua as the usage time to management system 50 (see FIG. 4B).

[0032] The management system 50 receives the usage ID, locking mechanism ID, and usage time via the system communication unit 64. The system control unit 52 acquires password constraint information from the lock table 60 based on the received locking mechanism ID (step S2). The system control unit 52 generates or acquires a password using the acquired password constraint information and the usage time transmitted from the business terminal 20, and sets the password, the password display type generated from the acquired password constraint information, and the usage time in the password management table 64 (step S3). Specifically, the system control unit 52 references the lock table 60 using the received locking mechanism ID, La, as a key to acquire Ra as password constraint information (step S2). The system control unit 52 generates or acquires a password Pa using the acquired password constraint information, Ra, and the usage time, Ua, transmitted from the business terminal 20, and sets the password Pa, the password display type T4, and the usage time Ua in the password management table 62 (step S3; see FIG. 2C).

[0033] The URL processing unit 54 generates a URL for the received usage ID and sets the URL in the password management table 62 (step S4). Specifically, the URL processing unit 54 generates a URL, URLa, for the usage ID Ia and sets the URL in the password management table 62 (see FIG. 2C).

[0034] The URL processing unit 54 transmits the URL to the business terminal 20 (step S5). Specifically, the URL processing unit 54 transmits URLa as the URL to the business terminal 20. In the business terminal 20, the received URL is stored in the terminal table 24 (step S6, see FIG. 4C).

[0035] In the management system 50, the system control unit 52 obtains a password from the password management table 62 based on the usage ID and transmits it to the locking mechanism unit 70 (step S7). Specifically, the system control unit 52 obtains a password, Pa, from the password management table 62 based on the usage ID, Ia, and transmits it to the locking mechanism unit 70. The locking mechanism unit 70 sets the password in the lock table 78 based on the received password (step S8). Specifically, the lock control unit 72 of the locking mechanism unit 70 sets Pa as the password in the lock table 78 (see FIG. 3B).

[0036] User A connects to the URL on user terminal 90 via business terminal 20, and connects to display processing unit 56 (step S9).

[0037] When the display processing unit 56 detects a connection based on a URL from the business terminal 20, it acquires the password, password display type, and usage time from the password management table 62 (step S10). Specifically, the display processing unit 56 acquires Pa as the password, T4 as the password display type, and Ua as the usage time from the password management table 62 based on the detected URL, URLa. The display processing unit 56 generates usage information that enables the password to be displayed based on the content of the acquired password display type, and transmits it to the business terminal 20 (step S11). Here, the usage information includes the password and may also include the usage time. Specifically, the display processing unit 56 generates the password Pa, which is included as information in the form of four-digit text, and the usage time Ua, which includes the start time 2024-01-01;10:00 and the end time 2024-01-02;10:00.

[0038] User A receives the usage information from the business terminal 20 at the user terminal 90 and displays it on the user terminal display unit 92 (step S12, see FIG. 6A). User A enters the password displayed on the user terminal display unit 92 into the lock input unit 80 of the lock mechanism unit 70 (step S13).

[0039] The lock control unit 72 compares the input password with the password stored in the lock table 78 (step S14). Specifically, the input password is Pa, while the password stored in the lock table 78 is Pa, which matches. Note that the lock control unit 72 compares the input password with the password stored in the lock table 78, and if it determines that they do not match, it may send a message to the user terminal 90 requesting that the password be resent.

[0040] Since the passwords match, the lock control unit 72 sends an unlock instruction to the lock / unlock unit 74 to unlock the lock mechanism unit 70 (step S15). User A is allowed to enter the facility 40.

[0041] As described above, the management system 50 acquires password constraint information, which is a restriction specific to the locking mechanism unit 70, from the lock table 60 based on the locking mechanism ID for identifying the locking mechanism unit 70 transmitted from the business terminal 20, and generates or acquires a password for locking and unlocking the locking mechanism unit 70 using the password constraint information and the usage time transmitted from the business terminal 20, and sets the password, a password display type indicating the display format of the password, and the usage time in a password management table; and and sets the URL in a password management table; a system 10 storage unit having the lock table 60 in which the locking mechanism ID and the password restriction information are stored, and the password management table 62 in which the usage ID, the locking mechanism ID, the usage time, the password, the password display type, and the URL are stored, and when a connection based on the URL is made from the business terminal 20, the display processing unit 56 obtains the password, the password display type, and the usage time from the password management table based on the URL and generates usage information that enables the obtained password to be displayed.

[0042] In addition, in the management system 50, the usage ID is set by the business terminal 20 and transmitted to the management system, or the system control unit 52 sets it for the lock mechanism ID and usage time transmitted from the business terminal 20.

[0043] Furthermore, the management system 50 unlocks the lock mechanism 70 using the usage information.

[0044] In addition, in the management system 50, if the terminal is a user terminal, the password is displayed in text on the user terminal display unit 92 of the user terminal 90, and the lock mechanism unit 70 is unlocked using the password.

[0045] In addition, in the management system 50, if the terminal is a user terminal, a two-dimensional code corresponding to the password is displayed on the user terminal display unit 92 of the user terminal 90, and the lock mechanism unit is unlocked using the two-dimensional code.

[0046] In the management system 50, by transmitting usage information, which is the locking / unlocking means, to the user in URL format via the business terminal 20, it is possible to centrally manage password restriction information, which is a restriction inherent to the locking mechanism, even when it differs. Furthermore, management can be performed using the same processing program regardless of the type of locking mechanism. Furthermore, by transmitting usage information in URL format, even if the locking mechanism ID, usage time, password, etc. are changed after the facility is reserved, there is no need to notify the user of the changed information again. This allows the system to be operated without burdening the user and with simplified terminal processing.

[0047] <Description of the embodiment related to the program> The above-described management system 50 is realized, for example, by a computer 100 configured as shown in Fig. 7. Fig. 7 is an explanatory diagram of hardware showing an example of the computer 100 that realizes the functions of the system 10. The computer 100 includes a CPU 110, a RAM 120, a ROM 130, an auxiliary storage unit 140, a network interface (NW I / F) 150, an input unit 160, an output unit 170, and a storage medium interface (storage medium I / F) 180. These units are connected by a bus 190.

[0048] The CPU 110 operates and controls each unit based on programs stored in the ROM 130 or the auxiliary storage unit 140. The ROM 130 stores boot programs such as a BIOS (Basic Input Output System) that are executed by the CPU 110 when the computer 100 starts up, and programs that depend on the hardware of the computer 100.

[0049] The auxiliary storage unit 140 is a large-capacity storage unit that stores programs executed by the CPU 110, data used by the programs, and the like.

[0050] The network interface 150 is a network interface for connecting to a public line.

[0051] The input unit 160 is an input device such as a keyboard, a mouse, etc. The input device may also include a touch panel, a camera, a microphone, etc.

[0052] The output unit 170 is a display unit such as a display, and may also include a speaker.

[0053] The storage medium interface 180 reads out a program or data stored in a recording medium and provides it to the CPU 110 via the RAM 120. Examples of recording media include optical recording media such as DVDs, DVD-RAMs, and Blu-ray (registered trademark) discs, semiconductor memories such as flash memories, magneto-optical recording media such as MOs, tape media, and magnetic recording media.

[0054] When the computer 100 functions as the management system 50, the CPU 110 reads a program from the auxiliary storage unit 140 and executes the program loaded onto the RAM 120, thereby realizing the functions of the public line 30. Alternatively, the CPU 110 may read a program from a recording medium via the storage medium interface 180 and execute the program loaded onto the RAM 120, thereby realizing the functions of the management system 50.

[0055] The management program stores in a lock table 60 a lock mechanism ID for identifying a lock mechanism unit 70 transmitted from the business terminal 20 and password constraint information which is a restriction specific to the lock mechanism unit 70, and in a password management table 62 stores the lock mechanism ID, the usage time transmitted from the business terminal 20, a usage ID for identifying a combination of the lock mechanism ID and the usage time, a password for locking and unlocking the lock mechanism unit 70, a password display type which indicates a display format of the password, and a URL for connecting to a display processing unit 56, and retrieves the password constraint information from the lock table 60 based on the lock mechanism ID transmitted from the business terminal 20. The computer is caused to execute the steps of acquiring information, generating or acquiring the password using the password restriction information and the usage time, and setting the password, the password display type, and the usage time in the password management table 62, generating the URL for the usage ID and setting the URL in the password management table 62, when a connection based on the URL is made from the business terminal 20, acquiring the password, the password display type, and the usage time from the password management table 62 based on the URL, and generating usage information that enables the acquired password to be displayed.

[0056] It should be noted that the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the gist of the present invention.

[0057] For example, in the above-described embodiment, the locking mechanism ID and usage time were transmitted from the business terminal 20 to the management system 50, but the locking mechanism ID and usage time may also be transmitted from the user terminal 90 to the management system 50.

[0058] Furthermore, in the above embodiment, the case where the password display type is T4 has been shown, but in the case of display type C, the password in the usage information is displayed as a two-dimensional code as shown in FIG. 6B.

[0059] Furthermore, in the above embodiment, user A inputs a password into locking mechanism unit 70, but it is also possible to unlock locking mechanism unit 70 without inputting a password. For example, as shown in Fig. 6C, user A may click on a connection URL, which causes display processing unit 56 to unlock locking mechanism unit 70.

[0060] Furthermore, in step 13 of the above-described embodiment, when user A receives the usage information at user terminal 90, the usage information is displayed on the user terminal display unit 92 of user terminal 90. However, the management system 50 may monitor user A's usage time, and if the usage time is outside the set usage time, the usage information may not be displayed on the user terminal display unit 92.
