[ description of the drawings ]
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, and are not to be considered limiting of the invention, in which:
FIG. 1 is a basic block diagram of the system of the present invention.
[ detailed description ] embodiments
The present invention will now be described in detail with reference to the drawings and specific embodiments, wherein the exemplary embodiments and descriptions are provided only for the purpose of illustrating the present invention and are not to be construed as limiting the present invention.
Referring to FIG. 1, a block diagram of the system of the present invention is shown. The remote door lock control system comprises a door lock, a door lock controller, a cloud management and control platform and a client.
The door lock is connected with the door lock controller and is controlled by the door lock controller; the outside of the door lock is provided with a small display screen which can display some simple information under the control of the door lock controller. The main function of the door lock controller is to control the opening and closing of the door lock, and on the other hand, to control the information to be displayed on the display screen (the information to be displayed is described later).
The cloud management and control platform is deployed on a cloud server, can be remotely connected with the door lock controller, is a core platform of the door lock control system, and is used for managing the door lock control system, including registration of owners, family member management, remote door lock opening, door lock switch record query and the like.
The client is a device used by a user for unlocking the door lock, and preferably, the client is a smart phone.
Based on the above system structure, the following describes the specific implementation process of the system of the present invention.
Before the door lock control system is used, an owner firstly needs to register on the cloud management and control platform. After registration, the owner can manage the issuance of door lock keys on the platform. The door lock key is actually a virtual key, i.e. a key triplet is registered on the platform: { user name, key, usage conditions }. Wherein the username is the name of the owner of the key; the key can be a group of biological characteristics, such as fingerprint characteristics or human face characteristics, and can also be a password; the use condition is a use condition of the key, including the number of times the key can be used, a time period during which the key can be used, and the like, for example, for a family member, the number of times the key can be used may be set to infinite, and the time period during which the key can be used may be set to an arbitrary time; for the clockwork, the usable times of the key are set to be once a day, and the usable time period is set to be the time for the key to work on the door every day; the number of times the key can be used is set to one for a door that needs to be opened temporarily. Through setting the use condition, the door lock key is more flexibly issued.
After the key is issued, the user with the key can use the key to open the door, and the specific process of opening the door by the system is as follows:
(1) the cloud management and control platform generates a random number, the random number is sent to the door lock controller, and the door lock controller controls the display screen on the outer side of the door lock to display the random number.
For safety, the random number is at least a decimal number with six digits, and the random number should be refreshed periodically, namely, a new random number is generated periodically (for example, 5 minutes) by the cloud management and control platform and sent to the door lock controller; in addition, after each door is opened, the cloud management and control platform must generate a new random number and send the random number to the door lock controller.
(2) The user uses the client side to input the key owned by the user and the random number displayed on the door lock display screen, and the client side encrypts the input key and the random number together and sends the encrypted key and the encrypted random number to the cloud management and control platform.
Preferably, the key owned by the user is a face feature or a fingerprint feature, and the client is a smart phone which has a face recognition function or a fingerprint recognition function, so that the face feature or the fingerprint feature of the user can be acquired as the key. If the client of the user does not have the face or fingerprint recognition function, the password can be used as a key. The specific type of key to which the user is assigned is determined by the owner at the time of the aforementioned registration of the key triplet.
The encryption uses an asymmetric encryption algorithm, namely, the public key of the cloud management and control platform is used for encryption, so that the public key can only be decrypted by the cloud management and control platform.
(3) And the cloud management and control platform decrypts the information sent by the client to obtain the key and the random number input by the client.
(4) The cloud management and control platform firstly determines whether the random number input by the client is the random number displayed on the current door lock display screen, if not, unlocking is refused, and if so, the subsequent steps are continued.
The reason why the random number is introduced in the invention needs to be explained, firstly, the random number can ensure that a malicious listener on a network cannot open a door lock in a mode of intercepting a network data packet, if the random number does not exist, a malicious hacker can intercept a door opening data packet of a normal client, although the hacker does not know how to decrypt the data packet, the hacker can resend the data packet to a cloud management and control platform to open the door lock, and the problem is solved by introducing the random number because the random number for opening the door every time is different. Secondly, the random number ensures that a person is at the door and the door can be opened only by obtaining the random number, thereby avoiding the danger of opening the door when no one is at the door.
(5) And the cloud management and control platform matches the key, namely judges whether a key triple K exists or not, wherein the key is matched with the key input by the client, if the matching is unsuccessful, unlocking is refused, and if the matching is successful, the subsequent steps are continued.
(6) The cloud management and control platform checks the use conditions in the key triple K, judges whether the use conditions of the key are met, if not, the unlocking is refused, and if so, the cloud management and control platform sends an unlocking signal to the door lock controller, and the door lock controller controls the door lock to be unlocked.
The cloud management and control platform needs to store the unlocking records of each key triplet, so that convenience is brought to subsequent inquiry of an owner on one hand, and whether the using conditions are met or not is judged on the other hand. If the use condition is to limit the total use times of the key, the use times in the use condition can be reduced by one after each unlocking, and the use condition cannot be used when the use times are reduced to zero.
(7) After the door lock is opened, the cloud management and control platform generates a new random number and sends the new random number to the door lock controller, and the door lock controller controls the display screen on the outer side of the door lock to display the new random number.
Through the scheme, the user can unlock the door lock together with the client by using the key distributed by the owner. Under special conditions, if a user needs to remotely open the door lock for a certain person (such as a temporarily visited relative), the random number on the display screen can be informed to the user by the person before and after the person arrives at the door, and the user can open the door lock by using the random number and the key of the user, so that remote unlocking is realized, convenience is brought to the user, and sufficient safety is ensured.
The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
