Drawings
The invention is described in detail below with reference to examples and figures, in which:
FIG. 1 is a flow chart of the intelligent lock management method of the present invention;
fig. 2 is a schematic diagram of the intelligent lock management system of the present invention.
Detailed Description
The embodiments of the invention are further illustrated in the following figures:
please refer to fig. 1. The intelligent lock management method comprises the following steps:
the first step is as follows: and setting an administrator password, a lock number and time on the intelligent lock, and activating the intelligent lock.
The purpose of setting the administrator password is that an administrator can manage the intelligent lock through the administrator password, and in subsequent management, the administrator password is used as a basis for verifying whether management information of the management end is sent by an authorized administrator.
The purpose of setting the lock number is to facilitate management. It is important to note that the lock number is not equivalent to the physical address of the smart lock. For the management of a plurality of intelligent locks, the management of each intelligent lock can be conveniently carried out subsequently by setting the lock number. Preferably, the lock number is set to a room number, so that it is very intuitive to see which room is being managed at the management side. Of course, the lock number may be set so that other administrators can intuitively know which intelligent lock they manage.
The setting of the lock number is exemplified below by taking the management of one apartment and two apartments as an example. If only one apartment is available, the apartment has 5 floors, each floor has 5 rooms, and each room is provided with one intelligent lock, at the moment, the room number can be used as the lock number, for example, the intelligent lock of the 501 room is numbered 501, and the intelligent lock of the 402 room is numbered 402. If two apartments exist, each apartment has 5 floors, each floor has 5 rooms, each room is provided with one intelligent lock, at the moment, the room number can still be used as the lock number, and the number of the apartment is added into the code of the room number for distinguishing different numbers, for example, the number of the intelligent lock of 1 apartment 501 is 1501, and the number of the intelligent lock of 2 apartment 402 is 2402. Obviously, if the intelligent lock is managed by simply using the physical address of the lock, the intelligent lock in which room is managed cannot be intuitively known, and the intelligent lock in which room is managed can be intuitively known by setting the lock number, so that the intelligent lock is very conveniently managed.
The time setting only needs to set the time of the intelligent lock to be accurate standard time, and if the current time is 11 o 'clock 45 minutes 6/5/2020, the time of the intelligent lock is set to be 45 minutes 11 o' clock 45 minutes 6/5/2020. The time setting aims to synchronize the time of the intelligent lock with the time of the management terminal and the time of the server, so that the generation and the corresponding management of the follow-up door lock secret key are facilitated.
The second step is that: and creating door lock management time information at a management end according to the administrator password and the lock number.
The management end is intelligent terminals such as smart mobile phones, tablet computers and computers generally, and an intelligent lock APP for managing the intelligent lock is installed on the management end. Because the smart phone is convenient to carry about and basically owned by people, the preferred management end of the intelligent lock management system is the smart phone, and an intelligent lock APP for managing the intelligent lock is arranged in the smart phone.
The administrator password and the lock number of the management end can be obtained through the following modes:
1. the method is obtained by directly inputting an administrator password and a lock number at a management end.
This kind of mode sets up administrator's password and lock serial number input interface on intelligent lock APP's interface, and its advantage lies in need not establishing any connection with the management end with the intelligent lock to make the intelligent lock need not realize the management through bluetooth or any external equipment of internet access, easy operation, it is very convenient to use, has avoided the security risk of being attacked that the intelligent lock brought because of the management end carries the virus when being connected with the management end moreover. Therefore, the administrator password and the lock number of the management terminal are preferably obtained by inputting the administrator password and the lock number at the management terminal.
2. Through passing through bluetooth or wired connection with management end and intelligent lock, the management end acquires administrator's password and lock serial number from the intelligent lock.
This kind of mode operation is more loaded down with trivial details, at first need pass through the bluetooth one-to-one with management end and each intelligent lock and establish the connection, wastes time and energy, and has the security risk that the intelligent lock is attacked because of the management end carries the virus and brings. Of course, the smart lock cannot be networked for security reasons.
When creating the door lock management time information, door lock management time information including the following may be created: short-time dynamic time information, validity period information, room reservation time information, and room cleaning time information. The administrator can select and create the door lock management time information according to actual needs. Wherein:
the short-time dynamic time information is mainly used for setting a short-time effective time so as to generate a short-time effective dynamic key for one-time unlocking in the following process, such as time information effective only in 15 minutes. The time of the short-time dynamic time information can be fixed by the intelligent lock APP generally, and only the option of the short-time dynamic time information or the option of the short-time dynamic password is reserved on the display interface of the intelligent lock APP for being selected by the administrator.
The valid period information is mainly used to set a valid period for subsequently generating a valid period key valid for a period. If the resident needs to live from 14 o 'clock at 5/1/2019 to 14 o' clock at 5/3/2019, the valid time period is set from 14 o 'clock at 5/1/2019 to 14 o' clock at 5/3/2019. The effective time period can be selected by an administrator according to actual conditions.
The room reservation time information is mainly used to set a reservation time for the subsequent generation of a reservation key. If the 501 room of the hotel of 1 st 2020 is reserved by the tenant for 2 nd 1 st 14 in 2020 to 2 nd 3 st in 2020, the room reservation time information can be set to be 2 nd 1 st in 2020 to 2 nd 3 st in 2020, and the valid period is from 2 nd 1 st 14 in 2020 to 2 nd 3 st 14 in 2020, and the lock can be unlocked by inputting the reservation key in the time period. Certainly, for convenience of management, whether the tenant is checked in on time or not can be seen, the booking key can also be a disposable key, the booking key is valid in the set check-in time period, and the intelligent lock reminds the checked-in tenant of applying for a new valid time period key to the administrator after receiving the valid booking key for unlocking, so that the administrator can conveniently learn whether the tenant is really checked in the set check-in time period or not. If the 501 room of the hotel is reserved by the tenant in 2020, 1 st and 1 st, 14 in 2020, 2 st and 1 st, and stays in 2020, 2 st and 3 st, the room reservation time information can be set to be 1 st and 2 st in 2020, and the validity period is from 14 in 2020, 2 st and 1 st to 18 in 2020, 2 st and 1 st, and the tenant can be unlocked by inputting the reservation key in the validity period and is reminded to apply for a new valid time period key.
The room cleaning time information is mainly used for cleaning rooms by cleaners so as to generate a cleaning key for the cleaners to unlock. The room cleaning time information may be set to a fixed time of day and the cleaning key is valid only for a set fixed period of time to facilitate sanitation of the room by the cleaner during the fixed period of time of day while preventing the cleaner from entering the room during the rest of the time.
The third step: the server acquires the administrator password, the lock number and the door lock management time information of the management end, generates a management secret key according to the administrator password, the lock number and the door lock management time information, and sends the management secret key to the management end; the server and the intelligent lock are internally provided with the same key management algorithm.
The management terminal is connected with the server through a network, the server obtains the administrator password, the lock number and the door lock management time information from the management terminal, generates a management secret key according to the administrator password, the lock number and the door lock management time information, and sends the management secret key to the management terminal.
The server and the intelligent lock are internally provided with the same key management algorithm so as to ensure that the intelligent lock and the key generated by the server are consistent. The key management algorithm can adopt a common encryption algorithm, and the preferred key management algorithm of the invention is an SHA-1 encryption algorithm.
When creating the door lock management time information, door lock management time information including the following may be created: short-time dynamic time information, validity period information, room reservation time information, and room cleaning time information. Accordingly, when the server generates a management key, a management key including a dynamic key corresponding to the short-time dynamic time information, a valid period key corresponding to the valid period information, a reservation key corresponding to the room reservation time information, and a cleaning key corresponding to the room cleaning time information may be generated.
And fourthly, sending the management secret key received by the management terminal to the user.
There are various ways to send the management key of the management end to the user, such as:
1. and inputting the telephone, the WeChat or the mailbox of the user at the management end, and automatically forwarding the management key to the user in the form of short message, WeChat or mail by the intelligent lock APP at the management end. When the information is transmitted in this way, the room information and the time information of the validity period can be attached to the information, so that the user can know the room where the user stays and the time of the stay. This is the most convenient way and is therefore preferred for sending the management key.
2. And (5) screenshot management keys are acquired at a management end, and the screenshots are sent to the user through WeChat.
3. The management key is directly input through the mobile phone and is sent to the user in a short message form.
Of course, the present invention does not limit the sending method, and only needs the user to obtain the management key of the management terminal.
The fifth step: and when the door lock secret key is consistent with the management secret key, the intelligent lock confirms that the management secret key is effective, and the intelligent lock is unlocked automatically.
Since the management key is generated according to the administrator password, the lock number and the door lock management time information, the server and the smart lock are internally provided with the same key management algorithm, and the smart lock is provided with the administrator password and the lock number, the door lock key generated by the smart lock according to the time of inputting the management key, the administrator password and the lock number and the management key generated by the server have consistency as long as the validity time of the door lock management time information. Therefore, after the effective management key is input into the intelligent lock, the intelligent lock is automatically unlocked.
In order to facilitate the invalidation of the generated management key and realize better management of the intelligent lock, the management method of the intelligent lock further comprises the steps of creating cancellation information for canceling the management key at a management end according to the administrator password and the lock number, generating a cancellation secret key by a server according to the administrator password, the lock number and the cancellation information, and sending the cancellation secret key to the management end; and inputting the cancellation key into the intelligent lock, and enabling the management key corresponding to the cancellation information to be invalid on the intelligent lock by the intelligent lock according to the cancellation key.
The method comprises the steps that cancellation information for canceling a management key is created at a management end, and a server generates the cancellation key, so that the intelligent lock is necessary to disable the management key corresponding to the cancellation information on the intelligent lock according to the cancellation key, and is necessary to manage hotels, apartments or rental houses. For example, a tenant is subscribed to check in for a certain period of time, and the administrator also sends the management key to the tenant, but for various reasons, the tenant does not check in or unsubscribe to a room, and at this time, if the original management key that has been sent out is not invalidated, the tenant can also enter the room by virtue of the original management key, so that potential safety hazards are brought to other checked-in tenants.
In order to facilitate the users who live in, especially the users who live in a long life, to use the unlocking key which is convenient for memorizing by themselves during the live in period, and do not need to use the management key to unlock each time, the intelligent lock management method of the invention also comprises the following steps: the intelligent lock identifies whether the input time of the management key exceeds the set time, and reminds a user to modify the management key after the input time exceeds the set time, and the modified management key is only valid in the valid range of the door lock management time information carried by the original management key.
For example, if the intelligent lock recognizes that the input time of the management key exceeds 5 hours, the intelligent lock reminds the user to modify the management key, modifies the unlocking key into an unlocking key which is convenient for the user to remember, and even modifies the unlocking key into a card or fingerprint unlocking and the like. However, the newly modified key is valid only within the valid range of the door lock management time information carried by the original management key, as with the original management key.
The setting makes the user very convenient of surviving, and it can be revised the secret key that unblanks for it of intelligence lock into the secret key that it was difficult for forgetting, prevents to forget the condition that manages the secret key and can not unblank and appear.
In addition, in order to make the time of the intelligent lock consistent with the time of the server, the invention also includes a method for calibrating the time of the intelligent lock by using the timing key, which comprises the following steps:
1. the server generates a time correction secret key carrying standard time information of the server and sends the time correction secret key to the management end.
And the management terminal sends a timing request to the server, and the server generates a timing key according to the administrator password and the lock number, wherein the timing key carries standard time information.
Of course, the management end may not send the timing request to the server, and the server may send the timing key to the management end at regular time. For example, every month, the server sends a timing key to the management terminal.
2. And the management end receives the timing secret key and sends the timing secret key to the user.
The mode of sending the timing secret key to the user by the management end is the same as the sending mode of the management secret key.
3. And the user inputs the timing secret key into the intelligent lock, and the intelligent lock calibrates the time of the intelligent lock according to the standard time information carried by the timing secret key.
And after receiving the timing secret key, the intelligent lock firstly decompresses the standard time information carried by the timing secret key, then compares the current time of the intelligent lock with the standard time information carried by the timing secret key, and if the current time of the intelligent lock is inconsistent with the standard time carried by the timing secret key, adjusts the current time of the intelligent lock to the standard time carried by the timing secret key.
In this adjustment mode, since there is an uncertain time difference between the time of generating the timing key and the time of inputting the timing key into the smart lock, the user is required to input the timing key in real time, so as to reduce the error caused by the uncertain time difference, otherwise, the timing of the smart lock is not accurate.
When the server generates the timing key, a time difference may be added to the time of the generation as the standard time carried by the timing key, for example, when the generation time is 13 in 6.1.2020, 13 hours and 05 minutes may be used as the standard time carried by the timing key, and a time difference of 5 minutes may be used as the time difference between the time of generating the timing key and the time of inputting the timing key into the smart lock.
Of course, in order to prevent the time calibration from being inaccurate due to too late input, a time threshold may be set on the smart lock, and when the difference between the standard time carried by the time calibration key and the current time of the smart lock exceeds the time threshold, the time for calibrating the smart lock is abandoned, and a warning that the calibration fails is issued. At this time, the administrator needs to obtain a new time correction key by inputting an administrator password or by sending a time correction request to the server again through the administrator terminal. When the calibration fails due to too late non-input, the time of the smart lock can only be calibrated by the administrator inputting the administrator password.
Of course, the administrator may also directly input the timing key on the smart lock according to the timing key of the management end, so as to calibrate the time of the smart lock.
The time of the intelligent lock is calibrated by using the time calibration secret key, so that the time of the intelligent lock can be calibrated by a user, and the condition that the time of the intelligent lock is privately modified when the time of the intelligent lock is calibrated by the user can be prevented, so that the management of the intelligent lock fails.
Referring to fig. 2, the intelligent lock management system of the present invention includes an intelligent lock, a management side and a server, and since there may not be a real connection between the management side and the intelligent lock, the management side and the intelligent lock are connected by a dashed arrow in the figure. Wherein:
an administrator password, lock number and time can be set on the intelligent lock to activate the intelligent lock.
The purpose of setting the administrator password is that an administrator can manage the intelligent lock through the administrator password, and in subsequent management, the administrator password is used as a basis for verifying whether management information of the management end is sent by an authorized administrator.
The purpose of setting the lock number is to facilitate management. It is important to note that the lock number is not equivalent to the physical address of the smart lock. For the management of a plurality of intelligent locks, the management of each intelligent lock can be conveniently carried out subsequently by setting the lock number. Preferably, the lock number is set to a room number, so that it is very intuitive to see which room is being managed at the management side. Of course, the lock number may be set so that other administrators can intuitively know which intelligent lock they manage.
The setting of the lock number is exemplified below by taking the management of one apartment and two apartments as an example. If only one apartment is available, the apartment has 5 floors, each floor has 5 rooms, and each room is provided with one intelligent lock, at the moment, the room number can be used as the lock number, for example, the intelligent lock of the 501 room is numbered 501, and the intelligent lock of the 402 room is numbered 402. If two apartments exist, each apartment has 5 floors, each floor has 5 rooms, each room is provided with one intelligent lock, at the moment, the room number can still be used as the lock number, and the number of the apartment is added into the code of the room number for distinguishing different numbers, for example, the number of the intelligent lock of 1 apartment 501 is 1501, and the number of the intelligent lock of 2 apartment 402 is 2402. Obviously, if the intelligent lock is managed by simply using the physical address of the lock, the intelligent lock in which room is managed cannot be intuitively known, and the intelligent lock in which room is managed can be intuitively known by setting the lock number, so that the intelligent lock is very conveniently managed.
The time setting only needs to set the time of the intelligent lock to be accurate standard time, and if the current time is 11 o 'clock 45 minutes 6/5/2020, the time of the intelligent lock is set to be 45 minutes 11 o' clock 45 minutes 6/5/2020. The time setting aims at synchronizing the time of the intelligent lock, the management terminal and the server, and facilitating the generation and corresponding management of the subsequent door lock secret key
