Thereafter, the operating company, for example, instructs the generation of permission data from a terminal connected to the key management server 4 (not shown), thereby performing Step S in FIG. 6 (hereinafter, "Step S" is simply referred to as "S"). ) 11, the control unit 40 (permission data generation unit 43) of the key management server 4 generates permission data for each management company, and stores the generated permission data in the permission data storage unit 53.

In S12, the control unit 40 (permission data transmission unit 44) refers to the property information storage unit 52 and transmits the generated permission data to the key storage box 1 of the rental property RP, which is the target property. For example, if rental property RP-A is managed only by management company X, the control unit 40 transmits permission data corresponding to management company X to the key storage box 1-A of rental property RP-A. do. Further, for example, in the case where rental property RP-B is managed by management companies X and Y, the control unit 40 controls the permission data corresponding to management company , and send it to the key storage box 1-B of the rental property RP-B.

In S13, the control unit 10 (permission data receiving unit 17) of the key storage box 1 stores the received permission data in the permission data storage unit 22 in response to receiving the permission data. Thereafter, the control unit 10 of the key storage box 1 ends this process.
In S14, the control unit 40 (key data generation unit 45) of the key management server 4 generates key data from the permission data.
In S15, the control unit 40 (key data transmission unit 46) transmits the generated key data to the mobile terminal 6 of the user of the management company corresponding to the permission data of the generation source.

In S16, the control unit 40 updates the status of the permission data storage unit 53. The updated status indicates that (1) key data has been generated from the permission data, (2) the generated key data has been sent to the mobile terminal 6 of the user who is an employee of the management company indicated by the management company ID, (3) Indicates that the permission data has been sent to the key storage box 1. Thereafter, the control unit 40 of the key management server 4 ends this process.
In S17, the control unit 60 (key data reception processing unit 62) of the mobile terminal 6 stores the received key data in the storage unit 65 in response to receiving the key data from the key management server 4. After that, the control unit 60 of the mobile terminal 6 ends this process.

In this way, the key management system 100 allows the key storage box 1 to store only the permission data of the management company that uses the key storage box 1 by processing the permission data and key data mainly using the key management server 4. be able to. Further, key data corresponding to the permission data can be stored in the management company's mobile terminal 6.
As a result, when a user inspects a rental property RP, he or she can unlock the key storage box 1 by holding the mobile terminal 6 and using the key data stored in the mobile terminal 6 in the key storage box 1. You will be able to do this.

Next, processing using key data will be explained.
FIG. 7 is a flowchart showing the main processing of the key management system 100 according to this embodiment.
FIG. 8 is a diagram showing a display example of the mobile terminal 6 and a usage example of the key storage box 1 using the mobile terminal 6 according to the present embodiment.
When using the key data, a user in possession of the mobile terminal 6 performs an operation to unlock the key storage box 1 in front of the key storage box 1.

When the user presses the switch 32 of the key storage box 1 with, for example, a finger, the control unit 10 of the key storage box 1 receives the operation of the switch 32 in S31 of FIG.
In S32, the control unit 10 of the key storage box 1 activates the camera 31.
Then, by operating the mobile terminal 6 carried by the user to start the mobile terminal program 66, the control unit 60 (key data output unit 63) of the mobile terminal 6 outputs the key stored in the storage unit 65. The data is displayed on the touch panel 67.

FIG. 8(A) is an example of the key screen 75 displayed on the touch panel 67 of the mobile terminal 6. Key screen 75 includes a two-dimensional code 75a. The two-dimensional code 75a is key data stored in the storage unit 65.
As shown in FIG. 8B, the user points the touch panel 67 of the mobile terminal 6 toward the shooting direction of the camera 31 so that the camera 31 reads the mobile terminal 6 on which the key screen 75 is displayed.
By doing so, in S33 of FIG. 7, the control unit 10 (key data reception unit 11) of the key storage box 1 acquires the key data. Note that when the key data is successfully acquired, the control unit 10 of the key storage box 1 may output sound, light, or the like to notify the user that the key data has been acquired, for example.

In S34, the control unit 10 (verification unit 12) collates the acquired key data with the permission data stored in the permission data storage unit 22.
In S35, the control unit 10 (verification unit 12) determines whether verification has been completed. If the verification is successful (S35: YES), the control unit 10 moves the process to S36. On the other hand, if verification is not possible (S35: NO), the control unit 10 ends this process. In other words, if verification is not possible, the key data obtained from the mobile terminal 6 is different. Therefore, in the key storage box 1, the key member 33a is not unlocked, and the key 71 cannot be taken out. Note that even if the verification is not successful, the control unit 10 of the key storage box 1 may, for example, output a sound, light, or the like to notify the user that the key data is invalid.

In S36, the control unit 10 (unlocking unit 13) unlocks the key member 33a. By doing so, the user can open the door portion 30 by pinching the handle member 33.
In S37, the control unit 10 (date and time acquisition unit 14, usage history registration unit 15) generates key usage data by the key detection unit 36 before and after unlocking, and registers the key usage data in the usage history storage unit 23.
In S38, the control section 10 locks the key member 33a when the door section 30 is closed. After that, the control unit 10 ends this process.

Through such processing, the key storage box 1 can be unlocked by only a person who has the key data that matches the permission data stored in the permission data storage section 22, and removes the key from inside. 71 can be taken out. Further, since key usage data including the stored state of the key by the key detecting unit 36 before and after unlocking is generated and registered in the usage history storage unit 23, the state of taking out the key 71, etc. can be stored as a history.

Note that the control unit 10 of the key storage box 1 transmits the key usage data stored in the usage history storage unit 23 to the key management server 4 at an appropriate timing. Then, the control unit 40 (usage history reception unit 41, reception history registration unit 42) of the key management server 4 receives the key usage data and registers it in the reception history storage unit 55. By doing so, the key management server 4 can centrally manage the key usage data sent from the key storage boxes 1 installed in various rental properties RP, and check the key usage data later. Can understand the situation.

Next, updating of key data will be explained.
The key data is updated, for example, when a user of a management company retires, in order to prevent the user from unlocking the key storage box 1 using the key data even after the user retires.
FIG. 9 is a flowchart showing the key data update process of the key management system 100 according to the present embodiment.

For example, the administrator of the management company requests the change of key data from the management screen (not shown) provided by the key management system 100, and in S51 of FIG. The requesting unit 61) transmits a key data change request to the key management server 4.
When the key management server 4 receives the key data change request, in S52, the control unit 40 (permission data generation unit 43) generates permission data for the requested management company. Then, the control unit 40 updates the permission data of the corresponding management company in the permission data storage unit 53 to the generated permission data.
In S53, the control unit 40 (key data generation unit 45) generates key data from the permission data generated in the process of S52.
In S54, the control unit 40 (key data transmitting unit 46) transmits the generated key data to the mobile terminal 6 of the management company.

The control unit 60 (key data reception processing unit 62) of the mobile terminal 6 that has received the key data causes the storage unit 65 to store the received key data in S55. At that time, it is desirable to delete the key data already stored in the storage unit 65.
In S56, the control unit 40 (permission data transmission unit 44) of the key management server 4 refers to the property information storage unit 52 and transmits the generated permission to the key storage box 1 of the rental property RP managed by the management company. Send data.
In S57, the control unit 40 updates the status of the corresponding record in the permission data storage unit 53. After that, the control unit 40 ends this process.
On the other hand, in S58, the control unit 10 (permission data receiving unit 17, permission data rewriting unit 18) of the key storage box 1 receives the permission data and rewrites the permission data in the permission data storage unit 22 to the received permission data. . After that, the control unit 10 ends this process.

Next, a process for inquiring about the usage status of the key 71 using the key storage box 1 will be explained.
The usage status inquiry is used, for example, by the owner of the rental property RP to confirm the extent to which the management company has guided his or her rental property RP.
FIG. 10 is a flowchart showing usage status inquiry processing of the key management system 100 according to this embodiment.

For example, the owner may instruct the output of an inquiry screen from an owner screen (not shown) provided by the key management system 100, so that in S71 of FIG. The received inquiry screen is displayed on the display unit.
The owner then inputs the details of the inquiry on the inquiry screen. The owner may specify, for example, a period to be queried. Further, the owner may further specify, for example, the property name and property ID of his or her own property. Then, when the owner performs an operation for making an inquiry, the control unit of the owner terminal 8 receives the inquiry content and transmits it to the key management server 4 in S72.

In the key management server 4 that has received the inquiry content, in S73, the control unit 40 (history inquiry processing unit 47) extracts key usage data from the reception history storage unit 55 based on the inquiry content. At this time, the control unit 40 extracts the key usage data of the property owned by the owner with the key storage device ID, and identifies the key usage data whose date and time are within the inquiry period from among the extracted key usage data.
In S74, the control unit 40 (history inquiry processing unit 47) uses the key storage information storage unit 54 to generate an inquiry result screen in which the contents of the identified key usage data are edited. The information regarding the key state included in the key usage data is, for example, information regarding the storage position of the key where the presence or absence of the key has changed before and after unlocking, and the information regarding the storage status of the key. Therefore, the control unit 40 uses the key storage information storage unit 54 to specify the room number from the storage position, and to specify lending and return based on the information regarding the change in whether or not the key is stored. Further, the control unit 40 identifies the management company name from the management company ID included in the key usage data.

In S75, the control unit 40 (history inquiry processing unit 47) transmits the generated inquiry result screen to the owner terminal 8.
In S76, the control unit of the owner terminal 8 that has received the inquiry result screen outputs the inquiry result screen. After that, the control unit of the owner terminal 8 ends this process.
By doing so, the owner can use the owner terminal 8 to grasp lending and return of keys stored in the key storage box 1. Therefore, the owner can check how often each management company conducts mediation (sales) to customers based on the usage status of the keys.

As described above, the key management system 100 of this embodiment has the following effects.
(1) The key storage box 1 installed in the rental property RP has a door part 30 at the opening of the box part 34, a key member 33a for locking and unlocking the door part 30, and an unlocking member for the key member 33a. It includes a camera 31 that reads key data used for the lock, and a permission data storage section 22 that stores permission data that permits unlocking of the key member 33a. The box portion 34 also includes a key hook member 35 for storing each key 71. Then, when the key detection unit 36 detects the storage state of the key hook member 35 and the key data read by the camera 31 matches the permission data stored in the permission data storage unit 22, the key member 33a is unlocked. Then, before and after unlocking, key usage data including the storage state of the key hook member 35 detected by the key detection unit 36 and information regarding the user that can be identified from the key data read by the camera 31 is recorded as a usage history. The information is stored in the storage unit 23.
Therefore, the key storage box 1 that stores and stores the key 71 can be unlocked using the key data, so the user only needs to have the key data, and since it is data, it is not necessary to transfer the key data. It can be done easily and can be made highly convenient. Further, since the key usage data including the usage status of the key 71 is stored as a history, the usage status of the key can be grasped later.

(2) Since the permission data to be checked against the key data is different for each management company, the key data can be different for each management company. Therefore, it is possible to ascertain which management company unlocked the key storage box 1 from the key usage data.

(3) The key data is code information represented by a two-dimensional code, and the camera 31 reads the two-dimensional code. Therefore, it can be easily constructed using existing technology. Furthermore, since the key data is a two-dimensional code, it can be easily read by the camera 31 by displaying it on the mobile terminal 6 or the like, for example.
(4) Since the key usage data includes the date and time information when the lock was unlocked, it is possible to know when the lock was unlocked.
(5) Since the key storage box 1 transmits the key usage data stored in the usage history storage unit 23 to the key management server 4, the key management server 4 stores the key usage data for each key storage box 1. be able to. Furthermore, by accessing the key management server 4, a management company or the like can conveniently check the unlocking status of the key storage box 1 based on the stored key usage data.

(6) Since the key management server 4 generates key data from the permission data and sends the generated key data to a predetermined mobile terminal 6, the key data can be displayed on the touch panel 67 of the mobile terminal 6, for example. can.
(7) The key management server 4 generates new permission data, generates key data from the generated new permission data, and transmits the generated key data to a predetermined mobile terminal 6. Therefore, when the permission data is changed, the mobile terminal 6 can receive key data generated from the changed permission data.
(8) The key management server 4 sends the generated new permission data to the key storage box 1, and when the key storage box 1 receives the new permission data, the key storage box 1 adds the permission data to the received new permission data. Rewrite the storage section 22.
Therefore, even if new permission data is generated, the key storage box 1 can check the key data using the new permission data.
