Description

The present invention relates to an electric lock.

As an electric lock that enables viewing without the need for the presence of an intermediary or the like, the one described in Patent Document 1 is known.

In this conventional example, the electric lock attached to the property for viewing can be electronically authenticated against the one-time password issued by the management device, and can be unlocked by the establishment of the authentication for viewing without the presence of an intermediary. Is formed in.

After that, when the move-in to this property is decided, the witness will accompany the resident and stop the electronic authentication function so that only unlocking with the mechanical unlock key is possible, and the structure of the electric lock will be changed. Change it so that it works only with the mechanical unlock key.

JP-A-2018-16994

However, in the above-mentioned conventional example, there is a drawback that a witness is required to move in when the move-in is decided because the conversion operation to the mechanical unlock key is possible.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an electric lock that does not require the presence of a witness when moving in after a contract is concluded.

According to the present invention, the above object
An authentication unit 2 capable of determining authentication for a one-time password issued by the password issuing device 1 and
It has a registration unit 3 that can register authentication information in the authentication unit 2.
A vacancy mode that unlocks on condition that the one-time password authentication is established by the authentication unit 2 and shifts to the locked state after a predetermined time has passed, and the one-time password authentication is stopped for the resident only. It is possible to transition between the move-in mode, which allows entry only by electronic authentication information,
The transition from the vacancy mode to the occupancy mode is achieved by providing the electric lock 4 executed by the process of registering the authentication information in the registration unit 3 after the unlocking operation by the one-time password.

In the present invention, the electric lock 4 includes an authentication unit 2 capable of authenticating a one-time password issued by the password issuing device 1, and a vacant room that enables an unlocking operation or an unlocking operation by the authentication of the one-time password. A transition is possible between the mode and the occupancy mode in which the unlocking operation is stopped by the authentication with the above one-time password and the unlocking operation is performed by the authentication for the electronic authentication information for the resident set for the resident. Will be done.

In the present invention, which is automatically locked after a lapse of a predetermined time when unlocked using a one-time password, it is automatically locked after the preview, so that the preview does not require a witness. ..

In addition, the electric lock 4 is provided with a registration unit 3 that can newly set and register authentication information, and when a rental contract for a property is concluded and a resident moves in, the resident is issued by the password issuing device 1. After unlocking using the one-time password, the resident authentication information can be newly registered using the registration unit 3. The electric lock automatically shifts to the occupancy mode by the registration operation by the user, and thereafter, the unlocking operation using the one-time password is prohibited, and the locking / unlocking operation using the resident authentication information is performed.

As the authentication information for the resident, in addition to the password set by the resident, a card key, an electronic key, a password stored in a portable storage medium such as a smartphone, or the like can be used.

Therefore, in the present invention, since the entry into the vacant room and the setting change of the electric lock can be performed only by the occupant 5, the witness does not need to be present, and the operation efficiency can be improved.

Further, the one-time password includes an identification element that distinguishes between a preview and a move-in.
When the transition from the vacancy mode to the occupancy mode constitutes an electric lock generated only by the process of registering the authentication information in the registration unit 3 after the unlocking operation by the one-time password including the occupancy identification element. Since the one-time password issued to the previewer is not given the registration authority to the registration unit 3, it is possible to reliably prevent the previewer from performing the transition operation to the move-in mode.

Further, the password issuing device 1 can issue a one-time password for eviction without unlocking authority including an identification element for identifying eviction.
If the move-in mode is configured with an electric lock that transitions to the vacant mode on the condition that the authentication for the move-out one-time password is established and the door is opened and unlocked, the resident moves out due to the cancellation of the rental contract of the resident. No need to witness.

Furthermore, since the one-time password for moving out is not given the unlocking authority, the electric lock will not be unlocked even if the authentication is established, and the transition to the vacant mode is the one for moving out. In addition to the authentication to the time password, the door is open and unlocked, so even if the one-time password for moving out is authenticated by mistake, the vacancy mode is entered, and then the resident is automatically locked. Will not be locked out.

Further, the password issuing device 1 can issue a construction one-time password including an identification element for identifying the construction.
In the vacant mode, the one-time password for construction is unlocked on condition that the authentication unit 2 establishes the authentication, and after the unlocking, the authentication information is registered in the registration unit 3 to transition from the vacant mode.
If an electric lock with a construction mode that automatically returns to the vacant mode after a predetermined period of time has elapsed after the transition is configured, the construction mode will be entered even if the operation of ending the construction mode and returning to the vacant mode is forgotten. After the transition, when a predetermined period elapses, the mode automatically shifts to the vacancy mode.

For this reason, since the mode has not changed to the vacant mode even though the construction has been completed, it is possible to surely prevent the situation that is not subject to the preview, and it is possible to improve the operation efficiency of the property. ..

Further, the one-time password is an encrypted code including an element indicating a valid period from the start date and time to the end date and time.
Authentication for the one-time password is performed from the time of issuance in a normal time-stamp type one-time password when an electric lock is configured such that the authentication is established on the condition that the authentication operation date and time is within the valid period. While the specified period is the valid period, the period during which the one-time password is valid can be started from the date that does not include the issue date, so any period that does not include the issue date is set as the reservation period. It becomes possible to do.

Further, the lock management system can be configured from the above electric lock 4 and a password issuing device 1 that issues a one-time password that can be authenticated by the electric lock 4 to the user at the request of the viewing applicant.

It is a block diagram which shows the lock management system. It is a flowchart which shows the operation of an electric lock. It is a flowchart which shows the operation of an electric lock.

FIG. 1 shows a lock management system of the present invention applied to a rental property. The lock management system includes a password issuing device 1 and an electric lock 4 installed on the door of the rental property.

The operation of the lock management system consists of 6 people who want to see the target property, 5 people who want to move in the target property, 7 people who want to move out of the target property due to cancellation of the rental contract, and 7 people who want to move out after the end of the rental contract. It will be conducted for construction personnel 8 such as cleaning contractors of the target property.

The password issuing device 1 has an input / output unit 1b, a one-time password generation unit 1c, and a property information storage unit 1d that are controlled and operated by the control unit 1a, and serves as a server connected to a communication network such as the Internet. It can be configured or installed and used in the stand-alone personal computer of the property manager 9 such as a rental broker.

The input / output unit 1b directly communicates with the above-mentioned viewing applicant 6 and the like when configured as a server, and specifies the property to be input by the property manager 9 when it is constructed in the stand-alone personal computer. Accepts the one-time password request and outputs the required one-time password to the viewing applicant 6 and the like.

The control unit 1a that has detected the one-time password request in the input / output unit 1b outputs the request to the one-time password generation unit 1c.

In the property information storage unit 1d, in addition to the identification code (property ID) such as the building name and room number of the rental property, detailed information such as the address can be stored, and in addition to the specific information of this property, Reservation information and current mode information are stored to prevent double booking.

Currently, the mode information includes "vacancy mode" corresponding to the state where there is no resident, "occupancy mode" in which the lessor is occupying, and "construction mode" corresponding to the vacancy mode. It corresponds to the state where the viewing by the viewing applicant 6 and the unlocking for the construction by the construction personnel 8 are possible.

Further, the occupancy mode corresponds to a state in which only the resident can unlock, and the construction mode corresponds to a state in which only the construction-related person 8 can unlock.

The one-time password is a character string that can be input to the password input unit 10 of the electric lock 4 described later. In this example, the property ID and the identification indicating the entry types such as preview, move-in, move-out, and construction are indicated. It contains an element and a lifetime element, and is encrypted for security. In this example, the validity period element includes the period start date and time and the validity period element from the start to the end, and by including these validity period elements, it is possible to reserve a preview that does not start from the current time. I have to.

In addition, the one-time password is determined by the situation such as the rental of the property, and the one-time password for viewing is the rental contract by the applicant 5 when the one-time password for viewing is requested by the applicant 6. If the one-time password for construction is established, the one-time password for construction will be used for the construction work by the construction personnel 8 who will clean and remodel the property, and the one-time password for moving out will be used when the resident's contract is canceled or the property is surrendered. , And issued at the start or end of construction.

Further, as the one-time password, a character string indicating the start date and time of the valid period can be directly encrypted, but in order to reduce the number of digits, for example, the "month" of the period start date and time can be used. When specifying, a two-digit number is required, but paying attention to the fact that the second digit takes only "0" or "1", the second digit "2" to "9" is an identification indicating the entry type. Various well-known compression methods can be used, such as using an element or a character string used as an area indicating an element of a period from the period start time.

Further, when the one-time password generation unit 1c generates the one-time password, consideration is given so that the reservation information of the property information storage unit 1d and the current mode are referred to so that the time when the room can be entered does not overlap.

On the other hand, the electric lock 4 has a storage unit 4b, a decoding unit 4c, an authentication unit 2, a registration unit 3, a timekeeping unit 4d, an authentication information input unit 4e, and a lock control unit 4f, which are controlled and operated by the control unit 4a. Further, a lock / unlock detection unit 4g for detecting the lock / unlock state and a door open / close detection unit 4h for detecting the opening / closing of the door are provided.

The electric lock 4 has an automatic locking function over time that automatically locks after a predetermined time elapses after unlocking. In this example, the locking / unlocking detection unit 4g of the timing unit 4d is an unlocking operation by the resident, accurately. Immediately after detecting the unlocking operation in the move-in mode, and after the registration time for mode change, which will be described later, has elapsed, the clock starts timing by the locking timer, the time of the locking timer is up, and the door opening / closing detection is detected. The locking operation is performed on condition that the transition to the closed door state is detected in the part 4h.

Further, in this example, in addition to the above-mentioned automatic locking function over time, a door closing automatic locking function is provided in which the door closing operation is performed when the door opening / closing detection unit 4h detects the door closing operation.

The property ID assigned to the property and the current mode are stored in the storage unit 4b. The current mode includes a vacancy mode, a occupancy mode, and a construction mode corresponding to the mode of the password issuing device 1, and the control unit 4a is used by the lock control unit 4f to control locking / unlocking according to the state of the current mode. Determine the lock timing.

That is, in the vacant room mode, after the unlocking operation is performed on the condition that the one-time password is authenticated, which will be described later, if the one-time password is for viewing, the time counting in the time measuring unit 4d is started and the predetermined time elapses. Later, it automatically shifts to the locked state. This function prevents the unlocked state from continuing after the preview is completed.

If the one-time password authenticated during the vacancy mode is for moving in or for construction work, the timekeeping unit 4d starts timing by the timer for registration in the registration unit 3, which will be described later, after unlocking. If the time is up without registering the registration timer, the lock state is entered.

Further, when the current mode is the move-in mode or the construction mode, the unlocking operation by the one-time password is restricted, and the unlocking operation is permitted only by the authentication information registered by the registration unit 3.

In addition, when the current mode is the move-in mode or the construction mode, when the one-time password is for moving out, the door open / close detection unit 4h detects the door opening, and the lock / unlock detection unit 4g is in the unlocked state. The mode shifts to the vacancy mode on the condition that Since the one-time password for moving out is not granted the unlocking authority, it is possible to grant the vacant mode transition authority only to the resident who has the authority to shift to the unlocked state or the construction personnel 8. it can.

Further, the electric lock is set with an automatic transition function to the vacancy mode on condition that the time of the construction mode timer is up in the construction mode. The construction mode timer is set in anticipation of the period until the end of construction, and even if the construction personnel 8 does not perform the transition operation to the vacant mode, the construction mode timer shifts to the vacant mode due to the time-up. Therefore, even if the construction is completed and the viewing is possible, the construction mode is continued, so that it is possible to surely prevent a problem that is not subject to viewing.

In this example in which a password-based authentication method and a card-key-based authentication method can be selected, the authentication information input unit 4e is provided with a password input unit 10 and a card reader 11 corresponding to each authentication method.

When the authentication information is input from the authentication information input unit 4e, the control unit 4a outputs the authentication information to the authentication unit 2 when the input is to the card reader 11, and the authentication information registered and stored in advance. If it matches, an authentication establishment signal is output. After confirming the output of the authentication establishment signal, the control unit 4a sets the unlock drive signal in the lock control unit 4f to unlock the lock.

On the other hand, when the authentication information is input to the password input unit 10, the current mode information in the storage unit 4b is inquired, and when the current mode is the move-in mode or the construction mode, the authentication unit 2 immediately performs the authentication operation. ..

After confirming the output of the authentication establishment signal, the control unit 4a sets the unlock drive signal in the lock control unit 4f to unlock the lock.

On the other hand, since the authentication information input to the password input unit 10 when the current mode is the vacant mode is a one-time password, the input authentication information decodes the encryption in the decryption unit 4c. As described above, the one-time password includes the validity period element, and the authentication unit 2 refers to the current date and time from the system clock, and outputs the authentication establishment information when the current date and time is within the validity period.

After confirming the output of the authentication establishment signal, the control unit 4a sets the unlock drive signal in the lock control unit 4f to unlock the lock.

The registration unit 3 is for registering unique authentication information for a new resident or a construction worker 8 in the authentication unit 2. The current mode is vacant mode, and one-time for occupancy or construction. It operates when the password is authenticated, or when the set authentication information is changed or added by the operation of the resident.

When the control unit 4a detects the completion of registration in the registration unit 3, the mode is switched to the move-in mode when the one-time password for moving in is used, and to the construction mode when the one-time password for construction is used. The current mode of the storage unit 4b is rewritten.

By rewriting the current mode, as described above, the unlocking operation using the authentication information registered in the registration unit 3, that is, the password or the card key is permitted.

In addition, when the mode is switched to the construction mode by registering the authentication information in the registration unit 3, a set period until the end of the construction is set in the timekeeping unit 4d, and the construction mode timer set in this construction period is timed up. Then, regardless of whether the construction is completed or not, the mode shifts to the vacant mode, and even if the above-mentioned construction-related person 8 forgets to switch to the vacant mode using the construction end one-time password, it is surely done. The transition to vacancy mode is made.

The operation flow of the electric lock 4 is shown below in FIG. At the time of control, first, the current mode is confirmed from the current mode information of the storage unit 4b, and in the case of the construction mode (step S1), the timing unit 4d is confirmed to determine whether or not the construction mode timer is timed up (step S1). Step S2). As described above, the construction mode timer has a set period until the end of construction, and when the construction mode timer times out during the construction mode, the mode is forcibly converted to the vacant mode (step S21). ..

On the other hand, when the construction mode timer is not timed up or there is no construction mode (step S1), it is determined whether the authentication information has been input to the authentication information input unit 4e (step S3), and the authentication information. If there is an input, it is determined whether the one-time password for viewing, moving in, or for construction is input (step S4). The determination is made by referring to the identification element included in the one-time password.

When the authentication information to the authentication information input unit 4e is the above-mentioned one-time password, the unlocking signal required for the lock control unit 4f is set and unlocked (step S5), and as shown in FIG. 3, the timekeeping unit 4d The registration timer is set in (step S6).

The registration timer is for setting the operation period for registering the dedicated authentication information for the construction personnel 8 or the resident, and the construction ID is registered before the time of this registration timer is up. That is, when the construction-related person 8 sets the password or the property manager registers the loaned card key to the authentication unit 2 via the registration unit 3 (step S7), the current mode changes from the vacant mode to the construction mode. Is switched to, and the current mode information of the storage unit 4b is rewritten (step S71).

Along with the switching to the construction mode, the timing by the construction mode timer in the timing unit 4d is started (step S72), and the locking timer for automatic locking over time is set (step S10).

If the construction ID is not registered in step S7, that is, if the one-time password is not for construction but for occupancy, the occupancy ID is registered, that is, the resident sets a unique password. Alternatively, when the property manager registers the lent card key (step S8), the current mode switches from the vacancy mode to the occupancy mode (step 81), and the process proceeds to step S10.

On the other hand, if the construction ID or the occupancy ID is not registered until the registration mode timer times out (step S9), step S10 is executed without switching the mode.

As described above, in this example, the electric lock has an automatic locking function when the door is closed in addition to the automatic locking function over time, and in addition to setting up the locking timer (step S12), before the time of the locking timer is up. Even if there is, when the door open / close detection unit 4h detects the transition to the closed state (step S11), the door closing automatic locking function is activated to shift to the locked state (step S13), and the control start point (step S1) is restored. ..

In this example, the case where step S10 or later is executed in any of the preview, construction, and occupancy is shown, but in the occupancy mode, the automatic locking function can be canceled by the resident's selection. You may.

On the other hand, when the authentication information entered in step S3 is not a predetermined one-time password but construction authentication information, that is, the authentication information registered in step S7 (step S41), or set by the resident. When the authentication information, that is, the one registered in step S8 (step S42), the unlocking operation is performed (step S43), and then the automatic locking operation of step S10 or lower is executed.

Further, when the authentication information input in step S3 is not the authentication information for construction or resident but the one-time password for moving out (step S421), that is, the resident moves out or the person involved in the construction 8 If it is a one-time password issued at the end of construction, the current mode is subject to the detection of the door open state by the door open / close detection unit 4h and the detection of the unlock state by the lock / unlock detection unit 4g (step S422). To the vacancy mode (step S433), and returns to the control start point (step S1).

As described above, when wishing to view the property, the person who wishes to view the property 6 goes directly to the property after receiving the one-time password for viewing, and enters the above-mentioned one-time password in the authentication information input unit 4e of the electric lock 4. Then, it can be unlocked and entered into the room, and after the preview is completed, it is automatically locked.

If the applicant decides to move in as a result of the preview, the applicant 5 receives the one-time password for moving in, unlocks the electric lock 4 with this one-time password, and then registers the authentication information for the resident within the predetermined time. After that, it becomes impossible to unlock with any one-time password, and you can live with peace of mind.

When the resident moves out, the move-out applicant 7 receives the one-time password for moving out, and then enters this one-time password into the authentication information input unit 4e to shift to the vacancy mode, and then sets it. Unlocking operation using the authenticated authentication information, that is, entering the room becomes impossible.

In addition, since the one-time password for moving out is not given the unlocking authority, it is not possible to enter the room with this one-time password, and the transition to the vacant mode requires the door to be opened and unlocked. Therefore, it is possible to reliably prevent the resident from being locked out by switching to the vacancy mode when the resident is absent by mistake.

As described above, when cleaning the room after the resident has moved out, all that is required is to use the construction one-time password issued by the construction personnel 8 and further register the construction ID. , It is possible to enter the room using the set authentication information, and when the construction is completed, it is possible to shift to the vacant room mode using the one-time password for moving out.

At the end of this construction mode, it is possible to prevent inadvertent lockout, and in the construction mode, the time counting by the construction mode timer is started from the start of the mode, and the construction mode does not require the operation associated with the end of the construction. Since the mode shifts to the vacancy mode when the timer time is up, even if the construction end operation is forgotten, it is possible to reliably respond to the preview request.

Furthermore, in any mode including preview, efficient operation is possible because the operation of the property does not require the presence of the property manager.
