(3) Operation Hereinafter, the operations of the electric lock system 100 and the electric lock device 1 of the present embodiment will be described.

(3.1) Normal Mode First, the operation of the electric lock system 100 in the normal mode will be described. Hereinafter, the operation when the doorway 5 is unlocked by using the key device 2 when the user 6 of the registered device 2A returns home will be described.

In the normal mode, the lock-side communication unit 11 of the electric lock device 1 intermittently transmits a beacon signal (for example, at intervals of about 0.1 to 2 seconds) according to a command from the lock-side control unit 14. The lock-side control unit 14 repeats a process of transmitting a beacon signal and a process of waiting for a beacon response for a certain period of time after transmitting the beacon signal at a predetermined cycle.

The user 6 approaches the doorway 5, and the key device 2 possessed by the user 6 is within a range (communicable range) in which communication is possible between the key device 2 and the electric lock device 1 with reference to the electric lock device 1. Upon entering, the key-side communication unit 21 receives the beacon signal from the electric lock device 1. When the key-side communication unit 21 receives the beacon signal, the key-side control unit 22 transmits a beacon response from the key-side communication unit 21 to the electric lock device 1.

Further, when the lock side communication unit 11 of the electric lock device 1 receives the beacon response, the authentication unit 141 starts the authentication process. When the authentication unit 141 starts the authentication process, the lock side control unit 14 transmits a request signal requesting key information from the lock side communication unit 11 to the key device 2. When the key side communication unit 21 of the key device 2 receives the request signal, the key side control unit 22 creates a response signal including the key information stored in the key side storage unit 24, and uses this response signal as the key side communication unit. It is transmitted from 21 to the electric lock device 1. When the lock-side communication unit 11 receives the response signal from the key device 2, the authentication unit 141 uses the key information included in the response signal and the identification information of the key device 2 as the authentication information stored in the lock-side storage unit 15. By collating, the key device 2 is authenticated.

Here, if the authentication of the authentication unit 141 fails, the lock side control unit 14 does not control the electric lock 13. On the other hand, when the authentication of the authentication unit 141 is successful, the lock side control unit 14 puts the electric lock 13 in a controllable state. When the user 6 presses the push button switch on the outside 42 side of the lock side operation unit 12 while the electric lock 13 can be controlled, the lock side control unit 14 outputs a control signal to the electric lock 13. Then, the electric lock 13 moves the dead bolt to the unlocking position according to the control signal. With the deadbolt moved to the unlocked position, the user 6 of the registered device 2A can enter the building 4 through the doorway 5.

(3.2) Registration Mode Next, the operation of the electric lock system 100 in the registration mode will be described with reference to FIGS. 3A and 3B. FIG. 3A shows a sequence diagram when the registration process is successful. FIG. 3B shows a sequence diagram when the registration process fails. Further, in FIG. 3B, the illustration of steps S100 to S104, which are common to those in FIG. 3A, is omitted.

As shown in FIG. 3A, first, the user 6 of the unregistered device 2B performs a predetermined operation on the lock side operation unit 12 of the electric lock device 1 for a predetermined period (for example, several tens of seconds) of the electric lock device. 1 shifts from the normal mode to the registration mode (step S100). Here, the "predetermined operation" is, for example, an operation of pressing the push button switch on the home 41 side of the electric lock device 1.

When the mode shifts to the registration mode, the registration unit 142 starts the registration process (step S101). With the registration unit 142 starting the registration process, the user 6 inputs the password (security code) required for registration by operating the key side operation unit 23 of the unregistered device 2B (step S102). The key side control unit 22 creates a registration request signal including the password input to the key side operation unit 23, and transmits the registration request signal from the key side communication unit 21 to the electric lock device 1 (step S103).

When the lock-side communication unit 11 receives the registration request signal from the unregistered device 2B, the registration unit 142 collates the password included in the registration request signal with the password stored in advance in the lock-side storage unit 15 (step). S104). When the received password matches the password stored in advance in the lock side storage unit 15, the registration unit 142 sends a registration signal including the key information to be assigned to the unregistered device 2B from the lock side communication unit 11 to the unregistered device. It is transmitted to 2B (step S105). Here, the registration unit 142 may create key information, or may select arbitrary key information from a plurality of key information stored in advance in the lock side storage unit 15.

The registration unit 142 stores the key information assigned to the unregistered device 2B in the lock side storage unit 15 in association with the unregistered device 2B as a part of the authentication information (step S106). When the key-side communication unit 21 receives the registration signal from the electric lock device 1, the key-side control unit 22 stores the key information included in the received registration signal in the key-side storage unit 24 (step S107). Here, the key side control unit 22 may create key information based on the information included in the received registration signal, and may store the created key information in the key side storage unit 24. In this case, the registration signal contains information necessary for creating the key information instead of the key information. Then, the lock side control unit 14 shifts from the registration mode to the normal mode (step S108). As a result, the unregistered device 2B is registered in the electric lock device 1. After that, the unregistered device 2B can be authenticated by the electric lock device 1 as the registered device 2A.

On the other hand, as shown in FIG. 3B, when the received password does not match the password stored in advance in the lock side storage unit 15, the registration unit 142 notifies the user 6 that the passwords do not match (step S109). ). In the present embodiment, the registration unit 142 notifies by transmitting a reply signal including information indicating that the passwords do not match from the lock side communication unit 11 to the unregistered device 2B (step S110). When the key side communication unit 21 receives the reply signal, the key side control unit 22 may display a message such as "The password is incorrect. Please re-enter" on the display unit 25, or the message concerned. The voice may be reproduced from the speaker provided in the key device 2. In addition, the notification may be performed by playing a voice such as "The password is incorrect. Please re-enter" from the speaker provided in the electric lock device 1.

Upon receiving the notification, the user 6 re-enters the password by operating the key-side operation unit 23 of the unregistered device 2B (step S111). The key-side control unit 22 creates a registration request signal including a password re-entered in the key-side operation unit 23, and transmits this registration request signal from the key-side communication unit 21 to the electric lock device 1 (step S112). After that, when an event in which the re-entered password does not match the password stored in advance in the lock side storage unit 15 occurs continuously for a predetermined number of times (for example, twice) (step S113), the registration unit 142 registers. The process is stopped (step S114).

Regardless of whether the registration of the unregistered device 2B in the registration process is successful or unsuccessful, the lock side control unit 14 stores in the lock side storage unit 15 that the process related to the registration process has been executed as execution information. Further, the lock side control unit 14 stores in the lock side storage unit 15 that the password change process, the password reference process, and the registration deletion process are executed in addition to the above-mentioned registration process as execution information.

(3.3) Notification Next, the notification operation by the notification unit 3 will be described with reference to FIG. Hereinafter, the operation when the user 6 of the registered device 2A returns home in the normal mode will be described.

As described above, in the normal mode, the lock-side communication unit 11 of the electric lock device 1 intermittently transmits the beacon signal according to the command from the lock-side control unit 14 (step S200). When the user 6 enters the communicable range and the key-side communication unit 21 receives the beacon signal from the electric lock device 1, the key-side control unit 22 transmits the beacon response from the key-side communication unit 21 to the electric lock device 1. (Step S201). Then, the authentication unit 141 starts the authentication process (step S202).

When the authentication of the authentication unit 141 is successful (step S203), the notification unit 3 reads the execution information from the lock side storage unit 15 and notifies the user 6 of the registered device 2A of the execution information (step S204). In the present embodiment, the notification unit 3 notifies by transmitting a notification signal including execution information from the lock side communication unit 11 to the registered device 2A (step S205). When the key-side communication unit 21 receives the notification signal, the key-side control unit 22 displays a message such as "There is a new registration" if the execution information includes information indicating that there is a new registration. Displayed in unit 25. Further, if the execution information includes information indicating that the registration has failed, the key side control unit 22 displays a message such as "registration attempted" on the display unit 25. In addition, if the execution information includes information indicating that the password has been changed, the key side control unit 22 displays a message such as "password changed" on the display unit 25.

(4) Advantages In the electric lock system 100 of the present embodiment, the notification unit 3 notifies the user 6 of the registered device 2A that the process related to the registration process has been executed as execution information. Therefore, in the present embodiment, the user 6 of the registered device 2A can know that the process related to the registration process has been executed.

Here, for example, when the family of the user 6 of the registered device 2A possesses the unregistered device 2B, the user 6 of the registered device 2A is processed by the user 6 (family) of the unregistered device 2B regarding the registration process. The time zone and situation of execution can be estimated to some extent. Therefore, the user 6 of the registered device 2A can presume that a third party other than the family has attempted unauthorized registration if the time zone and situation in which the process related to the registration process is executed are unexpected. .. The third party includes, for example, relatives, friends, and lovers of the user of the registered device 2A, as well as a courier company and a maintenance company. That is, the third party referred to here is mainly a person who has been invited to the house 41 of the building 4. It is considered that such a third party can operate the electric lock device 1 on the side of the house 41 depending on the situation, and may perform unauthorized registration.

For example, if the whole family is notified that the process related to the registration process has been executed during the trip, the user 6 of the registered device 2A can presume that the process related to the registration process has been executed by a third party. Is. Further, even if the time zone and the situation in which the process related to the registration process is executed are within the assumption, the user 6 of the registered device 2A executes the process related to the registration process by confirming with his / her family. It is possible to know whether or not. That is, the electric lock system 100 of the present embodiment makes it easy for the user 6 of the registered device 2A to recognize that an unauthorized registration has been attempted by a third party.

In the present embodiment, the key device 2 is provided with the permission unit 7, but the electric lock device 1 may be provided with the permission unit 7. In this case, the permission unit 7 stores the password included in the registration request signal even if the lock side communication unit 11 receives the registration request signal from the unregistered device 2B until the notification of the trial information is completed. Do not collate with the password stored in advance in Part 15.

In the present embodiment, the notification unit 3 is configured to only notify the user 6 of the registered device 2A of the trial information, but other configurations may be used. For example, the notification unit 3 may display a message to the effect that the trial information has been notified on the display unit 25 when the trial information is notified. In this case, if the user 6 of the unregistered device 2B is a third party who attempts unauthorized registration, the effect of suppressing the unauthorized registration by this third party can be expected. The message to the effect that the trial information has been notified may be reproduced as voice from the speaker provided in the unregistered device 2B.

In the present embodiment, the key side control unit 22 includes the notification unit 3 and the permission unit 7, but the permission unit 7 may not be provided. In this case, the user 6 of the unregistered device 2B can operate the key-side operation unit 23 to enter the password and continue the registration process without waiting for the notification of the trial information to be completed.

In the present embodiment, the notification unit 3 and the permission unit 7 are realized by the functions of the hardware (microcomputer) that constitutes the key side control unit 22, but may have other configurations. For example, at least one of the notification unit 3 and the permission unit 7 may be configured by hardware different from the key side control unit 22.
