<Overview of key management system 1>
FIG. 1 is a diagram showing an overview of a key management system 1. As shown in FIG.
The key management system 1 mainly consists of a key storage box 10 installed in the entrance hall or the manager's room of the housing complex H, and a key management server 30 that manages the use of the keys stored in the key storage box 10. It is configured. The maintenance contractor terminal 50 is operated by a maintenance worker for the equipment in the housing complex H, and is used to input a schedule for using a key to enter the equipment room or to request unlocking of the key storage box 10. The key storage box 10, the key management server 30, and the maintenance agent terminal 50 are communicably connected to each other via a publicly available communication line such as the Internet.

The key management server 30 is an information communication server operated by a management company that manages the housing complex H or a contractor commissioned by the management company. The key management server 30 is connected to the key storage box 10 of the housing complex H through a telecommunications line, and is used to manage and monitor the keys stored in the key storage box 10. The key management server 30 corresponds to a key management device.

The key storage box 10 stores keys for restricting entry to the equipment room of the housing complex H. The key storage box 10 is locked and managed, and is unlocked based on an unlocking permission signal and an unlocking operation transmitted by the key management server 30.
The key storage box 10 may store a key to the manager's room of the housing complex H. In this case, the maintenance worker can obtain the key to the manager's room stored in the key storage box 10, enter the manager's room, and then obtain the key to the equipment room stored in the manager's room. can.

The maintenance contractor terminal 50 is an information communication terminal used by a maintenance worker of the housing complex H and a person in charge of maintenance work. Specifically, the maintenance company terminal 50 is a smartphone, a tablet terminal, a PDA, or a desktop PC.

Below, the flow when a maintenance worker borrows the key to the equipment room of apartment complex H will be explained with reference to FIG.
[1] Prior to maintenance work, the maintenance worker sends key usage schedule information including the maintenance company name, certification number, real estate ID of apartment complex H, scheduled maintenance date and time, and information regarding the equipment room to be maintained to the key management server. 30 to register. Note that the maintenance provider may be registered prior to registering the key usage schedule information.

[2] On the day of the maintenance work, the maintenance worker operates the maintenance worker terminal 50 to read the QR code (registered trademark) 14a attached to the key storage box 10 installed in the entrance hall. The real estate ID of apartment complex H is displayed in an encoded state on the QR code. Therefore, the maintenance company terminal 50 can acquire the real estate ID of the housing complex H by reading the QR code.
[3] Next, the maintenance company terminal 50 transmits an unlock request signal including the maintenance company name, real estate ID, current time, and authentication number to the key management server 30 through the operation of the maintenance worker. Here, the authentication number is information used to authenticate the maintenance worker as a valid worker, and is input by the maintenance worker operating the maintenance worker terminal 50.

[4] Upon receiving the unlock request signal, the key management server 30 compares the unlock request signal with key usage schedule information registered in advance. More specifically, the maintenance company name, real estate ID, time information, and authentication number included in the key usage schedule information and the unlock request signal are compared to determine whether predetermined matching conditions are satisfied.
[5] If the verification is successful, the key management server 30 transmits an unlock permission signal to the key storage box 10. This allows the maintenance worker to unlock the key storage box 10 even when the manager is absent.

[6] When the key storage box 10 receives the unlocking permission signal, the unlocking operation of the key storage box 10 is enabled. When the maintenance worker performs the unlocking operation, the camera 17 disposed in the key storage box 10 takes a picture of the maintenance worker.

The cylinder lock 20 is used to unlock the door 12 using an emergency key when a power outage or the like occurs. By inserting an emergency key into the cylinder lock 20 and rotating it, the lock member 19a can be moved up and down.

<Functional configuration of key storage box 10>
Next, the functional configuration of the key storage box 10 will be explained.
FIG. 4 shows the functional configuration of the key storage box 10. As shown in FIG. 4, the control device 22 is connected to the unlock button 15, the camera 17, the LED lighting section 16, the locking device 19, and the communication device 21, and controls the key storage box 10. The control device 22 includes a processor, volatile memory, and nonvolatile memory. The processor of the control device 22 reads and sequentially executes the programs stored in the non-volatile memory, so that the control device 22 has an unlocking permission signal acquisition section 23, a photographing control section 24, a locking control section 25, and the like, which will be described later. It functions as a state control section 26.

The unlock permission signal acquisition unit 23 acquires an unlock permission signal from the key management server 30 via the communication device 21. Upon receiving the unlocking permission signal, the unlocking permission signal acquisition unit 23 controls the unlocking permission state display LED 18b to light up. Further, the unlocking permission signal acquisition unit 23 notifies the photographing control unit 24 and the state control unit 26 that the unlocking permission signal has been received. This allows the camera 17 to photograph the maintenance worker.

Upon receiving the notification of the unlock permission signal from the unlock permission signal acquisition unit 23, the photographing control unit 24 validates the operation on the unlock button 15. In other words, the photographing control unit 24 waits for a predetermined period of time (for example, 30 seconds) after receiving the notification of the unlocking permission signal until the unlocking button 15 is pressed. When the unlock button 15 is pressed, the photographing control section 24 lights up the LED illumination section 16 to brightly illuminate the maintenance worker and photographs the maintenance worker with the camera 17. Further, the photographing control section 24 outputs an unlocking signal to the locking control section 25 at the same time as photographing or after photographing is completed.
If the unlock button 15 is not operated within a predetermined time after receiving the notification of the unlock permission signal from the unlock permission signal acquisition unit 23, the unlock button 15 is disabled. In other words, the photographing control section 24 does not perform photographing even if the unlocking button 15 is operated, and does not output an unlocking signal to the locking control section 25.

When the locking control unit 25 receives the unlocking signal from the photographing control unit 24, it controls the locking device 19 to unlock the opening/closing door 12. Specifically, the imaging control unit 24 outputs a drive signal to the drive member 19b, thereby displacing the lock member 19a downward.
In addition, the lock control unit 25 transmits key usage record information consisting of the time when the lock device 19 was unlocked and an image taken by the maintenance worker acquired by the camera 17 to the key management server 30 via the communication device 21. do.

When the state control unit 26 receives notification of the unlocking permission signal from the unlocking permission signal acquisition unit 23, it causes the camera 17 to transition from the sleep state to the normal state. Here, the normal state is a state in which the camera 17 operates with normal power consumption, and is a state in which the camera 17 can automatically focus on and photograph a subject located in front of the camera 17. On the other hand, a sleep state (corresponding to a low power consumption state) is a state in which the device operates with lower power consumption than the normal state. In other words, the low power consumption state is a state in which the device is waiting to receive an unlocking permission signal, and the subject cannot be photographed.
The state control unit 26 controls the camera 17 to transition between a normal state and a low power consumption state. Further, upon acquiring the unlocking permission signal, the state control unit 26 causes the camera 17 to transition from the low power consumption state to the normal state, and also causes the camera 17 to transition from the normal state to the low power consumption state after shooting is completed. . Thereby, the power consumption of the camera 17 can be suppressed, and the energy saving performance of the key management system 1 can be improved.

The authentication number is input via the input device 51 by a maintenance worker.

<Sequence of key lending process>
Next, the sequence of key lending processing will be explained. The key lending process is a process executed by the maintenance company terminal 50, the key storage box 10, and the key management server 30. The explanation will be based on the assumption that, prior to the execution of the key lending process shown in FIG. 9, key usage schedule information is registered, and the key usage schedule information is stored in the key usage schedule database 35 of the key management server 30. conduct.

FIG. 9 shows the sequence of key lending processing. As shown in FIG. 9, when the maintenance worker arrives at the housing complex H to be maintained, he reads the QR code 14a of the key storage box 10 installed in the entrance hall. The control device 55 of the maintenance contractor terminal 50 determines whether the QR code 14a has been read by the QR code reading section 52 (step S10). If it is determined that the QR code 14a has not been read (step S10: No), the process waits until the QR code 14a is read.

If it is determined that the QR code 14a has been read (step S10: Yes), the control device 55 determines whether either lending or returning the key has been selected via the input device 51 of the maintenance company terminal 50. (Step S12). More specifically, the control device 55 causes the display device of the maintenance company terminal 50 to display an input screen for selecting whether the key is to be lent or returned. At this time, if the maintenance worker wishes to lend the key to start maintenance work, lending is selected. On the other hand, if the maintenance work is completed and the user wishes to return the key, return is selected.
If it is not determined that either lending or returning the key has been selected (step S12: No), the control device 55 waits until it is selected.

If it is determined that key lending or return has been selected (step S12: Yes), the control device 55 determines whether the authentication number has been input via the input device 51 of the maintenance company terminal 50 (step S14). ). More specifically, the control device 55 causes the display device of the maintenance company terminal 50 to display an input field for the authentication number, and accepts the input of the authentication number.
If it is determined that the authentication number has not been input (step S14: No), the control device 55 waits until the authentication number is input.

If it is determined that the authentication number has been input (step S14: Yes), the control device 55 generates an unlock request signal and transmits it to the key management server 30 (step S16). Here, the unlock request signal includes the maintenance company name, the real estate ID encoded in the QR code 14a read in step S10, the current time, and the authentication number acquired in step S14.

When the control device 38 of the key management server 30 receives the unlock request signal, it accesses the key usage schedule database 35 and acquires key usage schedule information (step S18). More specifically, the control device 38 acquires a record in which a maintenance business operator whose name matches the maintenance business name included in the unlock request signal is stored, from among the key usage schedule information stored in the key usage schedule database 35. do.

Next, the control device 38 of the key management server 30 compares the unlock request signal with the key usage schedule information (step S20). More specifically, the control device 38 first determines whether the unlock request signal and the real estate ID included in the key usage schedule information match. If the real estate IDs match, it is determined whether the current time information included in the unlock request signal is within a predetermined time difference from the scheduled maintenance date and time included in the key usage schedule information. If the current time information is within a predetermined time difference from the scheduled maintenance date and time, it is determined whether the unlock request signal matches the authentication number included in the key usage schedule information. If the above verification process is successful, the control device 38 transmits an unlock permission signal to the key storage box 10 to permit unlocking of the key storage box 10 (step S22). On the other hand, if the verification fails, the control device 38 notifies the maintenance contractor terminal 50 that the verification has failed.

Upon receiving the unlock permission signal, the control device 22 of the key storage box 10 validates the operation on the unlock button 15 (step S24). Then, the control device 22 prompts the maintenance worker to operate the unlock button 15 by lighting the unlock permission state display LED 18b. Further, the control device 22 may prompt the user to operate the unlock button 15 by outputting an audio signal.

Next, the control device 22 determines whether the unlock button 15 has been pressed (step S26). If it is determined that the unlock button 15 is not pressed (step S26: No), the control device 22 waits until the unlock button 15 is pressed.

If it is determined that the unlock button 15 has been pressed (step S26: Yes), the control device 22 controls the camera 17 to photograph the maintenance worker (step S28). More specifically, the control device 22 illuminates the maintenance worker located opposite the unlock button 15 with the LED illumination unit 16, and controls the camera 17 to photograph the maintenance worker. By having the maintenance worker operate the unlock button 15 in this manner, it is possible to make the maintenance worker face the unlock button 15 and effectively obtain a frontal photograph of the maintenance worker.

Next, the control device 22 unlocks the locking device 19 (step S30). More specifically, the control device 22 outputs a drive signal to the drive member 19b of the locking device 19 to displace the locking member 19a downward. This allows the maintenance worker to open the door 12 and borrow the key stored in the key storage space S.

Subsequently, the control device 22 transmits key usage record information to the key management server 30 (step S32). The key usage record information is information including the unlocking time and a photographed image. The key management server 30 that has received the key usage history information updates the key usage history database 36 and the photographed image storage unit 37 (step S34), and ends the key lending process.
The case where the maintenance worker receives the loan of the key has been described above, but the flow when returning the key is also the same.

By executing the key lending process according to the above-described procedure, it is possible to eliminate the need for manual key transfer and to reduce the cost associated with key management. Furthermore, even when maintaining and managing multiple buildings, it can be done efficiently (smoothly) by simply registering the key usage schedule in the key management server 30 without having to manage multiple IC cards. It becomes possible to lend and borrow keys, and it becomes possible to suppress delays in maintenance work on shared equipment.
