Bring the electronic lock device 103 to a position where the key card 104 can be read, and cause the electronic lock device 103 to read the key card 104. When the key data stored in the key card 104 is appropriate, the electronic lock device 103 performs a locking / unlocking operation to perform locking / unlocking. On the other hand, if the key data is not appropriate, the electronic lock device 103 does not perform the locking / unlocking operation and refuses to enter the room.
Hereinafter, the components of this system will be described.

[1.1. Key storage medium management device]
The key card management device 105 has a function of generating key data and storing the key data in the key card 104. The key card management apparatus 105 is connected to a reader / writer 106 for reading / writing data from / to the key card 104.

The key card management device 105 is an information processing device, and includes an arithmetic processing unit (CPU), a main memory (RAM), a read-only memory (ROM), an input / output device (I / O), and a hard disk device as necessary. This is realized by a device equipped with an external storage device such as the above and a program installed therein. Examples of the information processing apparatus include a computer and a workstation. A program for causing the information processing device to function as the key card management device 105 is stored in the ROM or an external storage device. The program is loaded on the main memory, and the CPU executes the program to manage the key card. A device 105 is realized. Further, the above program does not necessarily have to be stored in the storage device in the information processing apparatus, and is a magnetic disk, optical disk, magneto-optical disk, CD (Compact Disc), DVD (Digital
The program may be provided from a computer-readable program recording medium such as a video disc) or an external device (for example, an ASP (Application Service Provider) server) and loaded on the main memory.

  FIG. 2 is a functional block diagram showing a configuration example of the key card management device 105. The key card management apparatus 105 acquires from the database unit 203, which will be described later, a medium specifying data acquisition unit 201 that acquires card ID data, which is medium specifying data, from the key card 104 and a designated electronic lock device 103. The setup data acquisition unit 202, the card identification data acquired by the medium specifying data acquisition unit 201 and the setup data acquired by the setup data acquisition unit 202 are received, and key data that is generated based on these data is generated. A key data generation unit 205 to be stored in the key card 104, a database unit 203 capable of storing setup data in association with each electronic lock device 103, and storing other information (such as card ID data), Control and control the operation of these parts A control unit 206 for controlling the operation of the control unit, an input unit 207 (for example, a keyboard, a pointing device, etc.) for passing an operator's command as an electrical signal to the control unit 206, and an input / output interface screen or database unit 203 An output unit 208 (for example, a liquid crystal display device, a printer device, etc.) for displaying the contents of the received data and allowing the operator to browse the data.

  The key card management device 105 reads data stored in the key card 104 and writes data to the key card 104 (for example, a “Felica” card reader / writer “Pasori”; “Felica” and “Pasori” are connected to Sony Corporation. The key card management device 105 reads the card ID data via the reader / writer 106, and the key card 104 generates the key data generated by the key card management device 105. Can write.

  The key data is data generated by the key data generation unit 205 using the medium specifying data and the setup data. FIG. 3 shows an example of key data generation. In this example, the medium specifying data 301 and the setup data 302 are concatenated into one data, and data obtained by encrypting the concatenated data using a predetermined encryption method is generated. The encrypted data is called key data 303, and the key data 303 is written in the key card 104.

  FIG. 4 shows an example of data (referred to as “DB storage data”) stored in the database unit 203. In this example, the DB storage data 400 has one record 401 for each issued key card 104. Each record 401 has an electronic lock ID field 402, an initial verification data field 403, a medium specifying data field 405, an issuing authority ID field 406, a password field 407, and the like.

  The electronic lock ID field 402 is a field in which data that can uniquely identify the electronic lock device, such as a device ID and a manufacturing serial number, is stored. The initial verification data field 403 is a field for storing data for permitting locking / unlocking stored in an initial key card described later. The setup data field 404 is a field for storing setup data. The medium specifying data field 405 is a field for storing medium specifying data acquired from the key card 104 when the key data is issued. The issuance authority ID field 406 is a field for storing an issuance authority ID, for example, a user ID, which is identification data for identifying a person who has authority to issue key data. The password field 407 is a field for storing a password for proving that the issuing authority is the principal.

  When a certain person issues a key card, the electronic lock ID, issuer ID, and password of the electronic lock device 103 to be issued are input from the input unit 207. The control unit 206 collates these pieces of input information with the DB storage data 400, and operates to issue key data when all of these pieces of information match the stored data.

  The initial verification data stored in the initial verification data field 403 is unique data that is issued in advance by a manufacturer or the like and stored in the electronic lock device when the electronic lock device 103 is shipped. The initial verification data is notified to the administrator of the key card management apparatus 105 by the manufacturer or the like, and is input through the input unit 207.

  The setup data may be any data that can be distinguished from other setup data. For example, a series of unique IDs stored in a setup data table prepared in advance in the key card management apparatus 105 may be used as setup data. The setup data may be determined when the key card 104 is issued. In the state before the key card 104 is issued, the setup data field 404 does not need to store data.

  The medium specifying data field 405 stores medium specifying data 301 read from the key card 104 when the key card 104 is issued.

  Since the setup data 302 and the medium specifying data 301 are stored in the database unit 203, even if the key card 104 is lost, it can be reissued easily.

[1.2. Key card]
The key card 104 is a storage medium that can store the medium specifying data 301 and the key data 303 in a readable manner.

  The key-side data storage unit 503 stores the medium specifying data 301 in advance. The key-side data storage unit 503 preferably stores the medium specifying data 301 in such a manner that the medium specifying data 301 is not altered or changed. For example, it is preferable that the data is stored in a ROM chip by being burned at the time of shipment. The key data 303 may be stored in a state that can be changed at any time. For example, it may be stored in a rewritable memory such as a RAM.

  In the present embodiment, the medium specifying data 301 and the key data 303 are illustrated as being stored in the same key data storage unit 503. However, the medium specifying data 301 and the key data 303 are separated from a separate storage device (for example, a ROM). (RAM) may be stored.

[1.3. Electronic lock device]
The electronic lock device 103 performs locking / unlocking or unlocking according to the contents stored in the key card 104 when the person who tries to lock / unlock the electronic lock device 103 causes the electronic lock device 103 to read the lock. It is a device that rejects locks.

  FIG. 6 shows a configuration example of the electronic lock device 103. The storage medium reading unit 601 acquires the medium specifying data 301 and the key data 303 that are data stored in the key card 104 from the key card 104. The central control unit 602 receives the medium specifying data 301 and the key data 303 read from the key card 104 from the storage medium reading unit 601 and passes them to the determination unit 603. If the data read from the key card 104 is setup data 302, the central control unit 602 passes this to the writing processing unit 604.

When the write processing unit 604 receives the setup data from the central control unit 602, the write processing unit 604 writes the setup data in the lock side data storage unit 605.
When the determination unit 603 receives the medium specifying data 301 and the key data 303 from the central control unit 602, the determining unit 603 reproduces the medium specifying data reproduced from the key data 303 (hereinafter referred to as “reproducing medium specifying data” to distinguish it from the medium specifying data 301). ) And setup data (hereinafter referred to as “playback setup data” to distinguish it from the setup data 302) from the key card 104 and the setup data 302 stored in the lock data storage unit 605. In comparison, the electric lock driver 606 is requested to generate a drive signal based on the comparison result.

  FIG. 7 is a functional block diagram illustrating a configuration example of the determination unit 603. In the illustrated example, the determination unit 603 includes a decryption unit 701 and a collation unit 702.

  The decryption unit 701 has a function of decrypting the key data 303 by a predetermined decryption method to obtain reproduction medium specifying data and reproduction key data. FIG. 8 is a diagram illustrating the function of the decoding unit 701. When the decryption unit 701 returns the key data 303 to the original data by a predetermined decryption method, reproduction medium specifying data 801 and reproduction setup data 802 are obtained. The decryption method used here is a decryption method corresponding to the encryption method used when the key data management device 105 generates the key data 303. If the key card management apparatus 105 does not perform encryption, the decryption unit 701 need not be provided.

  Returning to FIG. 7, the description of the determination unit 603 is continued. The collation unit 702 included in the determination unit 603 has a setup stored in the medium identification data 301 and the lock side data storage unit 605 obtained by reading the reproduction medium identification data 801 and the reproduction setup data 802 obtained by the decryption unit 701 from the key card 104. The data 302 is compared to determine whether they match, and the electric lock driver 606 is requested to generate a drive signal according to the determination result. When the data obtained by the decryption by the decryption unit 701 is initial collation data (referred to as reproduction initial collation data), the collation unit 702 stores the initial collation data 607 stored in the lock side data storage unit 605. Are compared, and the electric lock driver 606 is requested to generate a drive signal according to the determination result.

FIGS. 9A and 9B show specific examples of collation processing that is processing performed by the collation unit 702.
When the collation unit 702 receives data from the decryption unit 701 or the like, the collation unit 702 first checks whether the setup data 302 is stored in the lock side data storage unit 605 (S901).

  When the setup data 302 is already stored in the lock side data storage unit 605 (S901, Yes), the collation unit 702 acquires the medium specifying data 301 read from the key card 104 from the central control unit 602 (S902). Next, the collation unit 702 temporarily stores the reproduction medium specifying data 801 and the reproduction setup data 802 separately (S903). Also, the collation unit 702 reads out and acquires the setup data 302 from the lock side data storage unit 605 (S904).

  The collation unit 702 compares the medium specifying data 301 with the reproduction medium specifying data 801 and determines whether or not these data match (S905). When it is determined that these data do not match (S905, No), the collation unit 702 does not perform the locking / unlocking operation (S908). That is, the electronic lock device 103 recognizes that the key card 104 is not an appropriate key, and does not perform the locking / unlocking operation. At this time, the collation unit 702 notifies the central control unit 602 that the locking / unlocking operation has been rejected, and the central control unit 602 notifies the user that the locking / unlocking operation cannot be performed, for example, the process of lighting an LED, generating a beep sound, etc. May be performed.

  On the other hand, when it is determined that these data match (S905, Yes), the collation unit 702 compares the setup data 302 and the reproduction setup data 802 to determine whether these data match (S906). When it is determined that these data do not match (S906, No), the collation unit 702 does not perform the locking / unlocking operation (S908). That is, the electronic lock device 103 recognizes that the key card 104 is not an appropriate key, and does not perform the locking / unlocking operation.

  On the other hand, if it is determined that these data match (S905, Yes), the collation unit 702 sends an instruction to the electric lock driver 606 to generate a drive signal (S907). As a result, the electronic lock device 103 recognizes that the key card 104 is an appropriate key and performs a locking / unlocking operation.

  In the process (S901) in which the collation unit 702 checks whether the setup data 302 is stored in the lock side data storage unit 605, which is the process described above, the setup data 302 is stored in the lock side data storage unit 605. An example of the operation of the collation unit 702 when it is not yet stored (S901, No) will be described with reference to FIG. In this case, the collation unit 702 reads out and obtains the initial collation data 607 from the lock side data storage unit 605 (S909).

  Next, the collation unit 702 compares the initial collation data received from the key card 104 via the decryption unit 701 and the like with the initial collation data 607 read from the lock side data storage unit 605, and whether these data match. Is determined (S910). When it is determined that these data do not match (S910, No), the collation unit 702 does not perform the locking / unlocking operation (S911). That is, the electronic lock device 103 recognizes that the key card 104 is not an appropriate key, and does not perform the locking / unlocking operation. At this time, the collation unit 702 notifies the central control unit 602 that the locking / unlocking operation has been rejected, and the central control unit 602 notifies the user that the locking / unlocking operation cannot be performed, for example, the process of lighting an LED, generating a beep sound, etc. May be performed.

  On the other hand, if it is determined that these data match (S910, Yes), the collation unit 702 sends an instruction to the electric lock driver 606 to generate a drive signal (S912). As a result, the electronic lock device 103 recognizes that the key card 104 is an appropriate key and performs a locking / unlocking operation.

Returning to FIG. 6, the description of the electronic lock device will be continued.
The lock side data storage unit 605 stores the initial collation data 607 from the beginning and also stores the setup data 302 passed from the writing processing unit 604. The electric lock driver 606 generates a drive signal for driving the electric lock 608 based on the determination result output from the determination unit 603.

The electric lock 608 includes a dead bolt that is a rod-like member formed of metal or the like, and a drive unit that causes the dead bolt (not shown) to move in and out of a key receiving hole (not shown) provided on the door frame side (not shown). (Abbreviated). The drive unit causes the dead bolt to move in and out of the key receiving hole in accordance with a drive signal from the electric lock driver. When the dead bolt is retracted from the key receiving hole by the drive unit, the unlocked state is established, and when the dead bolt is inserted into the key receiving hole, the unlocked state is established.
Above, description of the structural example of the electronic lock apparatus 103 and the electronic lock management system 100 is complete | finished.

[2. Example of operation of electronic lock management system]
Next, an operation example of the electronic lock management system 100 will be described.
[2.1. Issuance of initial key card and locking / unlocking with initial key card]
First, an example of operation when issuing an initial key card (also referred to as a “primary cons card”) and locking / unlocking with the initial key card in the electronic lock management system 100 will be described with reference to FIG. FIG. 10 is a sequence diagram showing an operation example when issuing an initial key card and locking / unlocking with the initial key card. The storage medium used as the initial key card 1001 may be a medium that can be read and written by the electronic lock device 103 and the key card management device 105, and may be the same as the storage medium used as the key card 104 in the future. It does n’t matter if it ’s different.

  In the electronic lock management system 100, an initial key that allows the electronic lock device 103 to perform an unlocking operation before an actual user / user of the property 101 enters and starts using the property. A card can be issued. The initial key card 1001 is a person who needs to enter or leave the property 101 before the user / user moves in and starts using the property, for example, during construction work of the property, during cleanup work, etc. It is issued to construction contractors (contractors, general contractors).

  Further, after completion of the construction, it may be issued to the owner of the property 101 or a management company entrusted by the owner. In this case, the initial key card 1001 is also called a secondary cons card. The secondary cons card may be issued separately from the primary cons card, or the primary cons card may be used as it is.

  First, common initial verification data 607 is stored in the electronic lock device 103 and the key card management device 105 (S1001, S1002). For example, the manufacturer and seller of the electronic lock device 103 store the unique initial verification data 607 in the electronic lock device 103 when the electronic lock device 103 is shipped or delivered, and the initial verification data 607 is stored in the electronic lock device 103. The data is stored in the database unit 203 of the key card management device 105 in association with the lock device ID.

  Next, when issuing an initial key card, the initial verification data 607 is written from the key card management apparatus 105 to a prepared storage medium (S1003), and the initial verification data 607 is stored in the storage medium (S1004). As a result, the storage medium functions as the initial key card 1001.

  Next, locking / unlocking with the initial key card 1001 will be described. When the user of the initial key card 1001 wants the electronic lock device 103 to perform the locking / unlocking operation, the user performs an operation of causing the electronic lock device 103 to read the initial key card 1001 (S1005). For example, the initial key card 1001 is brought close to the reading position of the electronic lock device 103.

  The electronic lock device 103 sends a data transmission request to the initial key card 1001 (S1006), and the initial key card 1001 transmits the stored initial verification data to the electronic lock device 103 in response thereto.

  The electronic lock device 103 that has received the initial verification data collates the initial verification data 607 stored in S1001 with the initial verification data 607 received in S1007 (S1008). If both the initial collation data 607 match as a result of collation, the electronic lock device 103 executes a locking / unlocking operation (S1009). Thereby, the holder of the appropriate initial key card 1001 can enter and leave the property 101.

[2.2. Setup process]
Next, the setup process in the electronic lock management system 100 will be described with reference to FIG. FIG. 11 is a sequence diagram illustrating an example of a setup process in the electronic lock management system 100.

  The setup process is a process for stopping the locking / unlocking by the initial key card in the electronic lock management system 100 and enabling the key card 104 to be issued.

  In order to start the setup process, the user first performs a setup data issue request operation using the key card management device 105 and the storage medium used as the setup card 1101 (S1101). As a specific example of the setup data issuance request operation, a user sets a storage medium as a setup card 1101 in the reader / writer 106, and the key card management apparatus 105 via the input means 207 has an electronic lock to be set up. The electronic lock ID of the device 103, the issuing authority ID, the password of the issuing authority, etc. are entered, and a setup card issuing process execution request is entered.

  Upon receiving the execution request, the key card management device 105 determines the setup data 302 to be assigned to the electronic lock device 103 (S1102), transmits it to the setup card 1101 (S1103), and stores it in the storage medium as the setup card 1101. Store (S1104). As a result, this storage medium functions as a setup card 1101. Note that the storage medium used as the setup card 1101 may be a medium that can be read and written by the electronic lock device 103 and the key card management device 105 as in the case of the initial key card and the original key card 104, and is used as a conventional initial key card. It may be the same as the storage medium that has been used or the storage medium that will be used as the key card 104 in the future, or may be different.

  After the setup card 1101 is completed, the user performs a registration request operation for the setup data 302 to the electronic lock device 103 using the setup card 1101 (S1105). A specific example of the registration request operation for the setup data 302 is that the user sets the setup card 1101 at the reading position of the electronic lock device 103.

  When the registration request operation is performed, the electronic lock device 103 transmits a data transmission request to the setup card 1101 (S1106). In response to this data transmission request, the setup card 1101 transmits the setup data 302 stored in S1104 to the electronic lock device 103 (S1107). The electronic lock device 103 that has received the setup data 302 writes the setup data 302 into the lock data storage unit 605 and stores it (S1108).

  Thus, the setup process is completed. After the setup process is completed, the electronic lock device 103 cannot be locked / unlocked by the initial key card 1001. Thereafter, only the person who owns the key card 104 can enter or leave the property 101.

[2.3. Issuance of key card and locking / unlocking with key card]
After the setup process is completed, the key card 104 can be issued, and the issued key card 104 can cause the electronic lock device 103 to perform a locking / unlocking operation. Hereinafter, with reference to FIG. 12, an example of the operation of the system in issuing a key card and locking / unlocking with the key card will be described.

  To issue the key card 104, first, the user performs a key card issue request operation using the key card management device 105 and a storage medium used as the key card 104 (S1201). As a specific example of the key card issuance request operation, the user sets a storage medium as the key card 104 in the reader / writer 106, and the target electronic lock device 103 via the input means 207 in the key card management device 105. The electronic lock ID, the issuing authority ID, the password of the issuing authority, and the like, and the key card issuing request command are input.

  When an issuance request is made, the key card management device 105 transmits a transmission request for the medium specifying data 301 to the storage medium serving as the key card 104 (S1202). In response to this data transmission request, the storage medium serving as the key card 104 transmits the medium specifying data 301 stored in the key side data storage unit 503 to the key card management apparatus 105 (S1203). The key card management device 105 that has received the medium specifying data 302 encrypts the set-up data 302 and the medium specifying data 301 corresponding to the target electronic lock device 103, which are set-up data stored in the database unit 203. To generate key data 303 (S1204).

  The key card management apparatus 105 transmits the generated key data 303 to the storage medium that becomes the key card 104 (S1205), and the storage medium that has received the key data 303 stores it in the key side data storage unit 503 ( S1206). As a result, the storage medium functions as the key card 104. The key card 104 issuance process is thus completed.

Next, the locking / unlocking operation of the electronic lock device by the key card 104 will be described.
When the user of the key card 104 wants the electronic lock device 103 to perform the locking / unlocking operation, the user performs a locking / unlocking operation for causing the electronic lock device 103 to read the key card 104 (S1207). As an example of the locking / unlocking operation, for example, the key card 104 is brought close to the reading position of the electronic lock device 103.

  When the locking / unlocking operation is performed, the electronic lock device 103 sends a transmission request for the medium identification data 301 to the key card 104 (S1208), and the key card 104 electronically stores the medium identification data 301 stored in response thereto. The data is transmitted to the lock device 103 (S1209). Further, the electronic lock device 103 sends a transmission request for the key data 303 to the key card 104 (S1210), and the key card 104 transmits the stored key data 303 in response to this to the electronic lock device 103 (S1211). ).

  Upon receiving the medium specifying data 301 and the key data 303, the electronic lock device 103 performs a collation process as shown in FIG. 9A (S1212). If both of the initial verification data match as a result of the verification, the electronic lock device 103 executes a locking / unlocking operation (S1213). As a result, the holder of the proper key card 104 can enter and leave the property 101.

[3. Modifications, etc.]
Hereinafter, modified examples of the electronic lock management system 100 according to the present embodiment will be described.
[3.1. Electronic lock management system using network]
The electronic lock management system may issue the key card 104 and the like in an environment remote from the key card management apparatus 105 using a network. FIG. 13 is a diagram illustrating a configuration example of the electronic lock management system 100 using a network. In this system, the key card management device 105 is connected to a data communication network 1301. The data communication network 1301 is connected to a network terminal device 1302 that is an information processing device such as a computer. The key card management device 105 and the network terminal device 1302 have a server / client relationship. When a request for issuing the key card 104 is sent from the network terminal device 1302 to the key card management device 105, the key card management device is responded to this request. 105 generates key data 303 and transmits the key data 303 to the network terminal device 1302 via the data communication network 1301. The network terminal device 1302 that has received the key data 303 writes the key data 303 to the storage medium by the local reader / writer 106 and issues the key card 104.

  According to such a configuration, a person who requests the issuance of the key card 104 can receive the issuance of the key card 104 at a convenient place without going to the place where the key card management device 105 is installed.

  In addition, a mobile phone (FOMA900iC; service name “i-mode Felica”, etc.) equipped with an IC chip having a so-called contactless IC card function has recently appeared. Such an IC card-equipped mobile phone 1304 has been introduced. If it is possible to connect to the key card management device 105 as a server via a network (mobile phone network 1302, data communication network 1301), the key data can be provided without providing the network terminal device 1302 and its local reader / writer 106. 303 can be downloaded to the IC card mobile phone 1304, and the IC card mobile phone 1304 can be used as the key card 104.

  With this configuration, the key card 104 can be issued at any time at a convenient location without going to the place where the key card management device 105 is installed.

[3.2. Independent key card management device (database) and electronic lock device (individual lock)]
As can be seen from FIG. 13, one of the features of this system is that the key card management device 105 that manages the setup data 302 and the electronic lock device 103 are not connected at all by communication. The medium / communication means for associating the setup data 302 managed by the key card management device 105 with the individual electronic lock device 103 is limited to the setup card.

  With this configuration, the setup data 302 is transferred from the key card management device 105 to the electronic lock device 103 not via communication but via a setup card. In other words, the so-called stand-alone electronic lock device 103 having no communication means can be easily associated with the key card management device 105, which is a central database for managing the setup data 302.

[3.2. Use of timed data]
In the electronic lock management system 100, the key card 104 stores data related to time such as the usable period of the key card 104, the start of use, and the end of use (called time limit data). It may be modified to read the time limit data and determine whether or not the locking / unlocking operation is permitted.

  In a system using such timed data, the key card 104 is valid from November 1 to December 31, or is valid for three months from the date of issue. It is possible to perform a control involving time such that the lock operation is prohibited after time o, and the lock operation is allowed from a certain time to N hours.

[3.3. Use of occupancy frequency data]
In the electronic lock management system 100, the key card 104 stores the number-of-occupancy data indicating the number of occupancy of the property (the number of occupant changes), and the electronic lock device 103 has the occupancy frequency data.

  For example, “1” is stored as the number-of-occupation data in the key card 104 issued to a resident who first moves into a certain property 101. At this time, the electronic lock device 103 also stores “1” as the number-of-occupancy data. Yes.

  Thereafter, when the resident moves away and a new resident is determined, the number-of-occupation data stored in the electronic lock device 103 is incremented to “2”. On the other hand, the number-of-occupation data “2” is stored in the key card 104 issued to a new resident. The determination unit 603 operates so that the electronic lock device 103 performs the locking / unlocking operation only when the number-of-occupation data matches. With such a configuration, even if the previous occupant uses the key card 104 storing “1” as the occupancy count data, the electronic lock device 103 does not perform the locking / unlocking operation.

  As a result, it is possible to ensure security without exchanging the electronic lock device 103 even if a resident changes.

[4. Second Embodiment]
Below, the 2nd form of this invention is demonstrated, referring FIG. FIG. 14 is a state transition diagram regarding the mode change of the electronic lock device 103 according to the present invention. The electronic lock device 103 is mainly used in a residence, a building, or a hotel that is rented or rented today. However, the electronic lock device 103 is not limited to these uses and can be applied to all movable and real estates that require locking.

  In the second mode of the present invention, the electronic lock device 103 includes a construction mode 1401 corresponding to the first mode, a vacant mode 1402 corresponding to the second mode, and a occupancy mode 1403 corresponding to the third mode. The three different states can be taken. The hardware configuration of the electronic lock device 103 is the same as that of the first embodiment.

[4.1. Construction mode]
The construction mode 1401 refers to an operating state of the electronic lock device 103 when a target to which the electronic lock device 103 is attached is a construction period, such as a building. The construction mode 1401 is a state set when the electronic lock device 103 is shipped. In the state of the construction mode 1401, the electronic lock device 103 performs a locking / unlocking operation when a construction card corresponding to a first card issued to a contractor or the like is read. The construction card is an authentication medium that is valid only during the construction period of the building and is invalidated after completion and delivery, and is generally in the form of a card, but may be a medium having other shapes, for example, A mobile phone having an IC card function can also be a construction card.
This construction card is a dedicated key card for the construction period and has the same hardware configuration as the key card 104, which is generally given to those who need to enter and exit the property before delivery, such as contractors and interior contractors. It is an electronic medium. Note that the construction card is associated with the corresponding electronic lock device 103, and only the associated electronic lock device 103 can perform the locking / unlocking operation.

  Note that the used construction card may be used for the electronic lock device 103 of another property, and the reuse of the card may be promoted.

[4.2. Transition from construction mode to vacant mode]
When the electronic lock device 103 is in the construction mode 1401 and a predetermined setup operation is performed on the electronic lock device 103, the electronic lock device 103 changes its state from the construction mode 1401 to the vacant mode 1402 corresponding to the second mode. Transition. The predetermined setup operation is, for example, causing the electronic lock device 103 to read a setup card corresponding to the fourth card. Alternatively, the predetermined setup operation may be to read an owner card, which will be described later, corresponding to the second card, or to register the owner card. Both the setup card and the owner card are storage media having the same hardware configuration as the key card 104 according to the first embodiment, and the electronic lock device 103 has identification information that can be identified from the setup card and the owner card. I remember it.

  The setup card is a medium used for transmitting setup data from the key card management device 105 to the electronic lock device 103, and is generally in the form of a card, but the setup card may be in other forms / shapes. It can be. The setup card is issued in a pair with each electronic lock device 103. Since the used setup card can be rewritten to be a setup card for another electronic lock device 103, there is an advantage that the card is not wasted.

  The owner card is an authentication medium possessed by the owner to whom the electronic lock device 103 is attached, such as a building, or a manager / manager, and is generally in the form of a card.・ Even if it is a shape, it can be a setup card. The owner card is a key card for a person in charge of management of the property (including part of the property) to which the electronic lock device 103 is attached, and is issued by a real estate management company or the like. A single owner card can be registered in a plurality of properties and used as a master key and a common key. It is also possible to issue a plurality of owner cards to the same electronic lock device 103.

  The electronic lock device 103 shifts its mode from the construction mode 1401 to the vacant mode 1402 by the predetermined setup operation. The transition from the construction mode 1401 to the vacant mode 1402 is irreversible, and once the electronic lock device 103 transitions to the vacant mode 1402, it cannot be returned to the construction mode 1401.

[4.3. Vacant mode]
The vacant mode 1402 refers to an operating state when an object to which the electronic lock device 103 is attached, such as a building, is not being leased or leased for hours. When the vacant mode 1402 is entered, the electronic lock device 103 does not perform the locking / unlocking operation even if the construction card is read. In the vacant mode 1402, the electronic lock device 103 performs a locking / unlocking operation when reading the owner card and a separately issued time card. As a result, in the property with the electronic lock device 103 in the vacant mode 1402, the property owner who owns the owner card, the manager, etc., and the real estate agent who is given the time card wish to purchase / rent You can enter the property for a preview.

  The timed card is a key card that is valid only in a predetermined room and period. It is also possible to issue a plurality of time cards to one electronic lock device 103. When there are a plurality of applicants for previewing at the same time, a time card is issued to each applicant for previewing and all preview requests are requested simultaneously. Person can enter the room. A single card can be a plurality of timed cards. As a result, there is an advantage that it is possible to preview a plurality of properties a day with a single time card.

[4.3. Transition from vacant mode to tenant mode]
When a predetermined operation is performed on the electronic lock device 103 in the vacant mode 1402, the electronic lock device 103 shifts to a occupancy mode 1403 corresponding to the third mode. The occupancy mode 1403 is a mode in which, for example, a purchaser or a borrower of a property determines, delivers the property to these people, and causes them to use the property thereafter.

  The predetermined operation for shifting to the occupancy mode 1403 is, for example, causing the electronic lock device 103 to read or register a resident card corresponding to the third card. The resident card corresponds to the key card 103 in the first embodiment. By moving to the occupancy mode with a resident card, the property is delivered with the reduction of the labor of the real estate company (such as accompanying the purchaser and resident) at the time of property delivery and occupancy and the delivery of the key. It is possible to maintain the current custom.

  The occupancy mode 1403 refers to an operating state of the electronic lock device 103 when a target to which the electronic lock device 103 is attached, such as a building, is being leased or leased for hours. When the occupancy mode 1403 is entered, the electronic lock device 103 performs the locking / unlocking operation using the resident card. Whether or not to perform the locking / unlocking operation with the owner card may be determined by the user's selection.

A resident card is an authentication medium possessed by a user who occupies and rents a target to which the electronic lock device 103 is attached, such as a building, and is generally in the form of a card, but other forms -It can be a setup card even if it is in shape.
The resident card is the above-mentioned [3.3. The same number of occupancy data as described in the section “Use of occupancy frequency data” may be stored, and the electronic lock device 103 stores and manages this occupancy frequency data so that only the latest occupant card is unlocked and unlocked. It is also possible to adopt a configuration in which the locking / unlocking operation is not performed on the previous resident card.

[4.4. Transition from occupancy mode to vacancy mode]
In general, when a resident moves out of a rental property, etc., the occupant remains in a vacant state until the next resident is determined. It becomes necessary to perform a locking operation.

  For this reason, even after the electronic lock device 103 according to the present embodiment once shifts to the occupancy mode 1403, it shifts again to the vacant mode 1402 by performing a predetermined operation.

  The predetermined operation for moving the electronic lock device 103 back to the empty room mode 1402 is, for example, operating an input means such as a switch or button provided on the indoor side of the electronic lock device 103 and reading the owner card, Etc.

  The electronic lock device 103 that has returned to the vacant mode 1402 does not perform the locking / unlocking operation with any resident card. The locking / unlocking operation is performed only by the owner card or the timed card issued in the ownership of the owner card, as in the case of the previous vacant mode 1402. Needless to say, if the resident decides again in this state, the electronic lock device 103 can be shifted to the occupancy mode 1403 again.

[4.5. Card loss correspondence]
When the above cards such as a resident card are lost, the card can be reissued using the key card management device 105. In this case, the reissued card has data indicating that it is reissued. When the electronic lock device 103 is read or registered, the electronic lock device 103 invalidates the previous card, Thereafter, even if the conventional card is used in the electronic lock device 103, the locking / unlocking operation is not performed. With this configuration, even when the card is lost, it is possible to maintain safety without allowing the suspicious person who has picked up the card to enter the room.
