Description

The present invention relates to a key management system that can easily open and close electronic locks of devices with electronic locks, such as vending machines, by reducing the processing load on mobile terminal devices owned by users such as workers.

In a vending machine, when an operator collects sales proceeds or replenishes products, an operator opens and closes an outer door that opens and closes a front opening of a main body cabinet, which is a rectangular heat-insulating casing with a front opening. To open and close this outer door, there are cases where a unified physical key is used, and cases where a physical key corresponding to each vending machine is used. Using a unified physical key reduces the burden on workers because there is no need to search for a physical key that is compatible with the vending machine, but it does take time to deal with lost keys. On the other hand, it takes time to search for a physical key that corresponds to the vending machine to be worked on, since a physical key that corresponds to each vending machine is used. Therefore, instead of a mechanical lock using a physical key, we installed an electronic lock that locks and unlocks electrically, and a vending machine that opens and closes the outer door by locking and unlocking the electronic lock based on wireless operation instructions. Yes (see Patent Document 1). Although Patent Document 1 uses a dedicated wireless terminal device (portable terminal device), a general-purpose wireless terminal device (portable terminal device) such as a smartphone can also be used.

Authenticate whether the authentication information is the user of the user identification information.

<Electronic lock control>
FIG. 8 is a diagram showing a control sequence for unlocking and locking the electronic lock. As shown in FIG. 8, first, the mobile terminal device 2 reads the barcode 40 affixed to the vending machine 1 and obtains the own machine identification information of the vending machine 1 to be unlocked (step S110). Thereafter, the mobile terminal device 2 transmits an unlock request including the read own device identification information and the user identification information of the own mobile terminal device 2 to the management server 3 (step S120).

When the management server 3 receives the unlock request, it refers to the electronic lock management information 32a and determines whether there is a combination of the received device identification information and user management information, and whether the current time is in the period of use, i.e. It is determined whether there is a schedule for unlocking (step S130). If there is an unlocking schedule (step S130, Yes), the management server 3 further acquires the user's biometric information from the vending machine 1 (step S140). Then, it is determined whether the acquired biometric information is the user's biometric information (step S150). If the biometric authentication is satisfied (step S150, Yes), an unlocking instruction is given to the vending machine 1 (step S160).

Upon receiving the unlock instruction from the management server 3, the vending machine 1 unlocks the electronic lock 19 (step S170). Thereafter, when the outer door opening/closing detection switch 18 is opened (step S180), the vending machine 1 notifies the management server 3 that the outer door is open (step S190). Thereafter, the operator (user) performs operations on the vending machine 1 such as collecting sales proceeds, replenishing products, and processing various settings.

After that, the vending machine 1 determines whether the outer door opening/closing detection switch 18 is closed (step S200). When the outer door opening/closing detection switch 18 is closed (step S200, Yes), an outer door closing notification is sent to the management server 3 (step S210). Note that if the outer door opening/closing detection switch is not closed (step S200, No), this process is repeated.

When the management server 3 receives the outer door closing notification from the vending machine 1, it transmits a locking instruction to the vending machine 1 (step S220). The vending machine 1 that receives this locking instruction locks the electronic lock 19 (step S230). Note that if there is no schedule for unlocking (step S130, No) or if biometric authentication has not been obtained (step S150, No), this process is ended as is.

In this embodiment, the electronic lock 19 can be unlocked simply by attaching a barcode 40 to the vending machine 1 and reading the barcode 40 by the mobile terminal device 2. At this time, by performing biometric authentication between the management server 3 and the vending machine 1, security can be improved without placing a burden on the user side and the mobile terminal device 2. Further, the management server 3 can use the electronic lock management information 32a to perform flexible work operations while maintaining a high level of security even if a sudden change in worker or work route occurs.

Note that in the embodiment described above, the biometric information acquisition unit 17 is provided on the vending machine 1 side, and the management server 3 acquires the biometric information from the vending machine 1, but the present invention is not limited to this. The biometric information acquisition unit 17 may be provided on the mobile terminal device 2 side, and the management server 3 may acquire the biometric information from the mobile terminal device 2.

<Modification 1>
FIG. 9 is a block diagram showing the configuration of the control system of the vending machine 1 according to the first modification. In this first modification, as shown in FIG. 9, the barcode 40 is displayed in a barcode display section 41 instead of being pasted. Then, the barcode 40 displayed in the barcode display section 41 is changed to the barcode 40 periodically sent from the management server 3 and displayed.

Here, when attempting to unlock the electronic lock 19 using the affixed barcode 40 without performing biometric authentication, the mobile terminal device 2 reads the barcode 40 in advance so that the user can It is possible to perform spoofing processing in which the user can normally issue an unlock instruction even if he or she is not in the vicinity of the device 1. That is, an unlock request made by a user other than the original user is processed as a normal unlock request. On the other hand, in Modification 1, the current barcode 40 can only be read by users who are around the vending machine 1 without performing biometric authentication, so the security of unlocking control can be increased. I can do it.

<Modification 2>
In this modification example 2, in order to confirm that the user is in the vicinity of the vending machine 1, the management server 3 is located close to the mobile terminal device 2 owned by the user who is in the vicinity of the vending machine 1. A connection check is performed by wireless communication to check whether the user who made the unlock request is in the vicinity of the mobile terminal device 2.

Also in the second modification, it is possible to confirm that there is a user around the vending machine 1, so the security of unlocking control can be improved.

<Modification 3>
In the third modification, the management server 3 instructs the electronic lock 19 to be locked if the electronic lock 19 remains unlocked for a predetermined period of time after the electronic lock 19 is unlocked. Normally, even if the electronic lock 19 is unlocked and the electronic lock 19 is unlocked, the outer door 1b remains unable to be opened and if the user leaves the vending machine 1, anyone can open the outer door 1b. Therefore, if the unlocked state has elapsed for a predetermined period of time, the management server 3 autonomously locks the electronic lock 19.

<Modification 4>
In this modification 4, when the outer door opening/closing detection switch 18 detects the open state after the electronic lock 19 is unlocked, and the open state has elapsed for a predetermined unlock state time, the management server 3 detects the unlock state. The mobile terminal device 2 that made the request is notified of this fact. Thereby, it is possible to prevent the continuation of an erroneous operation state in which the outer door 1b is left open.

Furthermore, in this case, the management server 3 causes the vending machine 1 to perform a short-range wireless communication connection with the mobile terminal device 2 that has made the unlock request, and based on the result of the short-range wireless communication connection. Next, it is confirmed whether or not the user who made the unlocking request exists around the vending machine 1 that is the subject of the unlocking request, and if it is confirmed, the above notification is not made.

<Modification 5>
In the above embodiments and modifications, electronic lock control is performed for the electronic lock 19 of the outer door 1b, but in this modification 5, one or more inner doors inside the vending machine 1 are controlled. One or more internal door electronic locks are provided, and the management server 3 controls unlocking and locking of not only the electronic lock 19 but also the one or more internal door electronic locks.

The one or more inner doors are, for example, the inner door 200 shown in FIG. 3, and the inner door 200 is unlocked and locked by an inner door electronic lock 201 arranged inside the outer door 1b. Items present inside the inner door 200 include a coin mechanism 13, a bill validator 14, a remote control 16, etc., and are used for tasks such as collecting sales proceeds and setting operations for the vending machine 1. On the other hand, it is possible to replenish the product storage 104 without opening the inner door 200.

When dividing work, for example, it can be divided into tasks such as money collection only, product replenishment only, and setting processing only. In this case, when the electronic lock 19 is unlocked, the internal door electronic lock 201 is also controlled to be unlocked, and for a worker (user) who only works to replenish products, only the electronic lock 19 can be unlocked. Let's do it. This prevents the electronic lock from being unlocked unless it is necessary for the work, thereby increasing security.

Note that the product storage 104 for one vending machine 1 may be shared and used by a plurality of vendors. In this case, for example, the product storage 104a is divided into company A, and the product storage 104b and 104c are divided into company B.
