In step S115, after setting the door lock, the server controller 130 provides an e-paper setting means to an administrator terminal or a user terminal, and obtains and stores e-paper information including at least one or more pieces of door-lock area information through the e-paper setting means.
When the door lock setting and e-paper setting are completed, the server controller 130 performs a door-lock use setting process in which the set door-lock setting information, i.e., the door-lock use setting information including the door-lock lock/unlock code and e-paper information is transmitted to the smart door lock part 60.
In the door-lock use setting process, as shown in
In step 121, when the smart door lock part 60 is the online type, the server controller 130 generates door-lock use setting information and performs online mode setting in which the generated door-lock use setting information is transmitted to the corresponding smart door lock part 60.
Whereas, in step S123, when the smart door lock part 60 is the offline type, the server controller 130 generates door-lock use setting information and performs offline mode setting in which the generated door-lock use setting information is transmitted to the corresponding smart terminal 50 of the user.
In addition, in step S125, the server controller 130 monitors whether a door-lock use cancellation request is generated, and in step S127, when the door-lock use cancellation request is generated, the server controller 130 determines whether the smart door lock part 60 is an online type or an offline type, and then in step S129, the server controller 130 performs an online smart door lock part 60 initialization process in which the use cancellation setting information of the smart door lock part 60 is transmitted to the smart door lock part 60.
Whereas, in step S131, when the smart door lock part 60 is the offline type, the server controller 130 performs an offline smart door lock part initialization process in which the use cancellation setting information of the smart door lock part is transmitted to the smart terminal 50 of the user.
Referring to
When the door lock signal is received, the lock terminal controller 240 determines whether the received door lock signal is door-lock use setting information (in step S215) or door-lock lock/unlock signal (in step S213).
In step S217, when the received door lock signal is the door-lock use setting information, the lock terminal controller 240 performs the door-lock use setting of the smart door lock part 60 according to the received door-lock use setting information.
After setting the use of the door lock, in step S219, the lock terminal controller 240 extracts e-paper information included in the door-lock use setting information and stores the e-paper information in the lock terminal storage 210, and then in step S221, the lock terminal controller 240 displays door-lock area information, which is basic regular e-paper information, on the e-paper part 232. The basic regular e-paper information is basic e-paper information arbitrarily set by the door-lock management part 30.
After displaying the basic regular e-paper information, in step S223, the lock terminal controller 240 checks whether an e-paper display information change request event occurs, and in step S225, when a change is requested, the lock terminal controller 240 displays, at a location of the selected e-paper, door-lock area information that is e-paper information changed by manipulation of the lock terminal input part 231.
Whereas, in a case where the received door lock signal is a door-lock lock/unlock code received through the third short-range communication part 223, the lock terminal controller 240 determines whether the received door lock signal is a door-lock lock signal (in step S227) or a door-lock unlock signal (in step S229). In general, locking of a door lock is often performed automatically, so it is common to determine whether a door-lock unlock signal is received. Therefore, the door-lock lock signal may be generated as an event in the smart door lock part 60.
When a door-lock lock signal or a door-lock lock event occurs, in step S231, the lock terminal controller 240 instantly displays the e-paper information on the e-paper part 232 at a time of locking. For example, the e-paper information according to the locking may be changed from “Occupancy” to “Absence”.
Whereas, in a case where a door-lock unlock signal is received, in step S233, the lock terminal controller 240 instantly displays the e-paper information on the e-paper part 232 at a time of unlocking.
In step S235, the e-paper information may be displayed only for a predetermined period of time.
After the e-paper information is displayed according to the locking or unlocking for the predetermined time, the lock terminal controller 240 displays the regular e-paper display information on the e-paper part 232. The regular e-paper display information may be the same as or different from the last changed e-paper information.
In addition, the lock terminal controller 240 may be configured to display the e-paper information only when an object or a person approaching a door is detected through the approach sensor 290.
First, in the case of a hotel, when a hotel guest or hotel manager presses a DND or MUR button of the lock terminal input part 231 wirelessly connected to the smart door lock part 60 through any one of Zigbee and Bluetooth Low Energy (BLE), the lock terminal controller 240 changes and displays user state information, which is door-lock area state information displayed on the e-paper part 232.
In addition, in the case of an office and school, when a user changes user state information by using an application after connecting to the smart door lock part 60 through wireless communication such as BLE through the applications installed in his/her own smart terminal 50, the lock terminal controller 240 changes the previously displayed user state information, which is the door-lock area state information, to the user state information selected by the user.
In addition, in the case of a locker, when a user inputs the RF card and PIN through the lock terminal input part 231 or changes the state of a locker through the smart terminal 50, the lock terminal controller 240 of the smart door lock part 60 locks or unlocks the locker by moving a latch of the door lock part 300, and automatically changes state information accordingly and displays the state information on the e-paper part 232.
