The door lock server 300 mentioned in the embodiment of the present application may be a dedicated door lock server specially configured for the unlocking function provided in the embodiment of the present application, or may be a door lock server with other data processing functions, and the embodiment of the present application is not particularly limited.

In the embodiment of the present application, the terminal device 100 and the door lock 200 may communicate with each other through bluetooth, a wireless network, or the like.

An unlocking method applied to the unlocking system shown in fig. 1 will be described below with reference to fig. 2. Referring to fig. 2, this figure is a signaling interaction diagram of an unlocking method provided in the embodiment of the present application.

The unlocking method shown in fig. 2 may be realized, for example, by steps S101 to S107 as follows.

It should be noted that the terminal device shown in fig. 2 may be the terminal device 100 shown in fig. 1; the door lock shown in fig. 2 may be the door lock 200 shown in fig. 1; the door lock server shown in fig. 2 may be the door lock server 300 shown in fig. 1.

S101: and the terminal equipment sends an unlocking request to the door lock, wherein the unlocking request carries the user identification.

In this embodiment, the terminal device may first establish a communication connection with the door lock, and then send an unlocking request to the door lock. For example, when the user is closer to the door lock, the terminal device may be controlled to establish bluetooth connection with the door lock, and then the terminal device sends an unlocking request to the door lock through bluetooth communication. For another example, the terminal device may establish a connection with the door lock through a wireless network, and then the terminal device sends an unlocking request to the door lock through the wireless network.

In this embodiment, the terminal device sends an unlocking request to the door lock, which may be triggered by a user. Specifically, the user can trigger a corresponding unlocking operation on the terminal device, and the terminal device responds to the unlocking operation triggered by the user, generates the unlocking request, and sends the unlocking request to the door lock.

The embodiment of the present application does not specifically limit a specific implementation manner in which the user triggers the unlocking operation on the terminal device. As an example, an unlocking application may be installed on the terminal device, and a user may log in a corresponding account on the unlocking application, and then trigger a corresponding unlocking operation on a preset interface displayed by the unlocking application, so that the terminal device generates the unlocking request based on the unlocking operation. The preset interface is not specifically limited in the embodiment of the application, and the preset interface may be a certain interface displayed by the unlocking application program. The embodiment of the present application also does not specifically limit the unlocking operation, and the unlocking operation may be, for example, a user clicking a certain function button displayed on the preset interface.

It should be noted that, in the embodiment of the present application, the unlocking request carries a user identifier. In this embodiment, the user identifier may be used to identify a user identity using the terminal device. In an implementation manner of the embodiment of the present application, if the unlocking request is generated by the terminal device based on an unlocking operation triggered by a user on an unlocking application installed on the terminal device, the user identifier may be embodied as a user identifier corresponding to an account corresponding to the unlocking application. The embodiment of the present application does not specifically limit the user identifier corresponding to the account corresponding to the unlocking application, and as an example, the user identifier corresponding to the account corresponding to the unlocking application may be, for example, an account ID (identity) which is an identification number of the account corresponding to the account.

S102: and when the door lock determines that the user corresponding to the user identification has the unlocking right for the door lock, determining the binding mobile phone number corresponding to the user identification.

It is understood that in practical applications, not all users have the right to unlock the door lock. Therefore, in the embodiment of the present application, after the door lock receives the unlocking request, it is first determined whether the user corresponding to the user identifier has the unlocking authority for the door lock.

In the embodiment of the application, the door lock can determine whether the user corresponding to the user identifier carried in the unlocking request has the unlocking authority for the door lock according to the legal user identifier having the unlocking authority for the door lock and the user identifier carried in the unlocking request. In practical application, one door lock can correspond to a plurality of users with unlocking authority, one user can also correspond to a plurality of door locks, and the user identification can bind the user and the door lock to determine the mapping relation between the user and the door lock.

The embodiment of the present application does not specifically limit a specific implementation manner of determining, by a door lock, whether a user corresponding to a user identifier carried in an unlocking request has an unlocking right for the door lock, and as an example, the door lock may determine an identifier of the door lock, that is, an identifier of the door lock, and determine whether a mapping relationship exists between the identifier of the door lock and the user identifier carried in the unlocking request, and if a mapping relationship exists between the identifier of the door lock and the user identifier carried in the unlocking request, it indicates that the user identifier carried in the unlocking request is a legal user identifier having the unlocking right for the door lock, so the door lock may determine that the user corresponding to the user identifier has the unlocking right for the door lock.

It should be noted that the mapping relationship between the identifier of the door lock and the user identifier may be stored in the door lock, or may be stored in a door lock server, and the embodiment of the present application is not specifically limited. If the mapping relation is stored in the door lock, the door lock can search the mapping relation stored by the door lock, so that whether the mapping relation between the identification of the door lock and the user identification exists or not is determined. If the mapping relationship is stored in the door lock server, the door lock may send a mapping relationship query request to the door lock server, and request the door lock server to determine whether the mapping relationship between the identifier of the door lock and the user identifier exists.

In the embodiment of the present application, it is considered that, in practical application, a user corresponding to the user identifier has an unlocking right for the door lock, and does not necessarily indicate that a user currently using the terminal device to initiate an unlocking request is a valid user having an unlocking right for the door lock. For example, the unauthorized user steals the unlocking application account of the legitimate user, and logs in the unlocking application account of the legitimate application by using the unlocking application installed on the terminal device of the unauthorized user. In this case, although the door lock determines that the user corresponding to the user identifier carried in the unlocking request has the unlocking authority for the door lock, the user who actually initiates the unlocking request using the terminal device is not a legitimate user who has the unlocking authority for the door lock.

In view of this, in the embodiment of the present application, the identity of the user who currently initiates the unlocking request by using the terminal device may be further verified, so as to determine whether to perform the unlocking operation.

In the embodiment of the application, the identity of a user using the terminal equipment can be represented to a certain extent by considering the mobile phone number of the SIM card installed in the terminal equipment. Therefore, in the embodiment of the application, the identity of the user who uses the terminal equipment to initiate the unlocking request can be verified by using the mobile phone number corresponding to the SIM card installed in the terminal equipment.

In the embodiment of the application, when the unlocking right of the door lock is initially given to the user corresponding to the user identifier, the identifier of the door lock, the user identifier and the mobile phone number of the user can be bound. Namely, the mapping relation among the identification of the door lock, the user identification and the mobile phone number of the user is saved. For convenience of description, the mobile phone number of the user included in the mapping relationship is referred to as a "bound mobile phone number". It can be understood that the mapping relationship between the identifier of the door lock and the user identifier may be regarded as a part of the mapping relationship between the identifier of the door lock, the user identifier, and the bound mobile phone number. Because the mapping relationship among the identifier of the door lock, the user identifier and the bound mobile phone number actually comprises three pairs of mapping relationships, which are respectively: the mapping relation between the identification of the door lock and the user identification, the mapping relation between the identification of the door lock and the binding mobile phone number, and the mapping relation between the user identification and the binding mobile phone number.

In the embodiment of the application, when the door lock determines that the user corresponding to the user identifier has the unlocking right for the door lock, a bound mobile phone number corresponding to the user identifier can be further determined, so that the identity of the user who currently uses the terminal device to initiate the unlocking request can be verified by using the bound mobile phone number and a mobile phone number corresponding to an SIM card installed in the terminal device.

In the embodiment of the application, the door lock can determine the bound mobile phone number corresponding to the user identifier according to the mapping relation between the user identifier and the bound mobile phone number. The mapping relationship between the user identifier and the bound mobile phone number can be stored in the door lock or in a door lock server, and the embodiment of the application is not particularly limited. If the mapping relation is stored in the door lock, the door lock can search the mapping relation stored by the door lock, so that the bound mobile phone number is determined. If the mapping relation is stored in the door lock server, the door lock can send a binding mobile phone number query request to the door lock server to request the door lock server to determine the binding mobile phone number.

S103: and the door lock sends the binding mobile phone number to the terminal equipment.

S104: and the terminal equipment acquires the identifier of the SIM card installed in the terminal equipment.

In the embodiment of the application, the terminal equipment can acquire the identifier of the SIM card installed in the terminal equipment, so that the identity of the user who uses the terminal equipment to initiate the unlocking request at present is further verified according to the acquired identifier of the SIM card and the binding mobile phone number.

In the embodiment of the application, the identifier of the SIM card can be used to uniquely identify the SIM card, and the mobile phone number corresponding to the SIM card can be determined by using the identifier of the SIM card. The identifier of the SIM card is not specifically limited in the embodiments of the present application, and the identifier of the SIM card may be, for example, an authorization token corresponding to the SIM card.

It should be noted that, in the embodiment of the present application, a specific implementation manner of a terminal device acquiring an identifier of a SIM card installed in the terminal device is not specifically limited. As an example, the unlocking system provided by the embodiment of the present application may further include an operator server in addition to the terminal device, the door lock, and the door lock server. The terminal device may obtain, from the operator server, an identity of a SIM card installed in the terminal device. Specifically, the terminal device may call a preset interface, send an SIM card identifier acquisition request to the operator server through the preset interface, and receive the identifier of the SIM card sent by the operator server. The preset interface is not specifically limited in the embodiment of the present application, and the preset interface may be, for example, a token interface provided by an operator.

It should be noted that in the embodiment of the present application, S104 does not necessarily need to be executed after S103, and S104 may also be executed between S101 and S103, and S104 may even be executed simultaneously with S101.

S105: and the terminal equipment sends the identification of the SIM card and the bound mobile phone number to a door lock server.

S106: and the door lock server sends an unlocking instruction to the door lock when determining that the mobile phone number corresponding to the SIM card is consistent with the binding mobile phone number.

S107: and the door lock executes unlocking action according to the unlocking instruction.

And after the terminal equipment acquires the identifier of the SIM card and receives the bound mobile phone number sent by the door lock, the terminal equipment sends the identifier of the SIM card and the bound mobile phone number to a door lock server. And determining whether the mobile phone number corresponding to the SIM card is consistent with the bound mobile phone number by the door lock server. And when the door lock server determines that the mobile phone number corresponding to the SIM card is consistent with the bound mobile phone number, the user who uses the terminal equipment to initiate an unlocking request currently is a legal user with the unlocking authority of the door lock. Therefore, the door lock server can send an unlocking instruction to the door lock, and the door lock executes unlocking action after receiving the unlocking instruction, so that the unlocking purpose is achieved. And when the door lock server determines that the mobile phone number corresponding to the SIM card is inconsistent with the bound mobile phone number, the door lock server indicates that the user currently utilizing the terminal equipment to initiate an unlocking request may not be a legal user with the unlocking authority of the door lock. Therefore, the door lock server can not send an unlocking instruction to the door lock, so that certain loss of a legal user with the unlocking authority of the door lock is avoided.

In this embodiment of the application, it is not specifically limited that the door lock server determines that the mobile phone number corresponding to the SIM card is consistent with the specific implementation manner of the binding of the mobile phone number, and as an example, the door lock server may determine the mobile phone number corresponding to the SIM card identifier, and then determine whether the mobile phone number corresponding to the SIM card identifier is consistent with the binding of the mobile phone number. The embodiment of the application does not specifically limit the implementation manner of the door lock server according to the identification of the SIM card determines the mobile phone number corresponding to the SIM card, as an example, the door lock server can store the identification of the SIM card and the mapping relation between the mobile phone numbers corresponding to the SIM card, so that the door lock server can determine the mobile phone number corresponding to the identification of the SIM card according to the identification of the SIM card and the mapping relation between the mobile phone numbers corresponding to the SIM card. As another example, the door lock server may determine, by means of an operator server, a mobile phone number corresponding to the identity of the SIM card. For example, the door lock server sends a mobile phone number acquisition request to an operator server, wherein the mobile phone number acquisition request carries the identifier of the SIM card, and receives the mobile phone number returned by the operator server, so as to determine the mobile phone number corresponding to the identifier of the SIM card.

As another example, the operator server may verify whether a mobile phone number corresponding to the SIM card is consistent with the bound mobile phone number, and then send a verification result to the door lock server. Specifically, the door lock server may send an authentication request to the operator server, where the authentication request includes an identifier of the SIM card and the bound mobile phone number. And after receiving the verification request, the operator server further determines the mobile phone number corresponding to the SIM card identifier, and determines that the mobile phone number corresponding to the SIM card is consistent with the bound mobile phone number. And after the operator server determines that the mobile phone number corresponding to the SIM card identification is consistent with the bound mobile phone number, the operator server sends a verification result indicating that the mobile phone number corresponding to the SIM card is consistent with the bound mobile phone number to the door lock server.

As can be seen from the above description, with the unlocking system provided in the embodiment of the present application, it is first verified whether the user corresponding to the user identifier carried in the unlocking request has the unlocking authority of the door lock, and then verified whether the user currently using the terminal device to initiate the unlocking request is a legitimate user having the unlocking authority of the door lock, so that the unlocking security is ensured. Moreover, the user does not need to remember the unlocking password in the whole unlocking process, unlocking can be achieved by utilizing the terminal equipment, and the user operation is simple and convenient.

In order to enable a user to determine an unlocking result corresponding to the unlocking request through the terminal device, in an implementation manner of the application embodiment, the door lock server may further send an unlocking success message to the terminal device after sending the unlocking instruction to the door lock; and when the door lock server determines that the mobile phone number corresponding to the SIM card is inconsistent with the bound mobile phone number, the door lock server can also send an unlocking failure message to the terminal equipment. After receiving the unlocking success message or the unlocking failure message, the door lock can display the unlocking success message or the unlocking failure message, so that a user determines a corresponding unlocking result according to the content displayed by the terminal device, and can also inform an indicator lamp or a player at the door lock end of success or failure prompt, for example, when the unlocking is successful, the indicator lamp at the door lock end is green, the player is a short prompt tone, when the unlocking is failed, the indicator lamp at the door lock end is red, and the player is a long prompt tone.

In another implementation manner of the embodiment of the present application, the door lock may also send the unlocking success message or the unlocking failure message to the terminal device. Specifically, after the door lock performs the unlocking action, an unlocking success message may be sent to the terminal device. If the terminal device does not execute the unlocking action within the preset time after receiving the unlocking request, the unlocking failure is indicated, and at the moment, the door lock can send an unlocking failure message to the terminal device. After receiving the unlocking success message or the unlocking failure message, the door lock can display the unlocking success message or the unlocking failure message, so that a user can determine a corresponding unlocking result according to the content displayed by the terminal equipment. It will be appreciated that the unlocking result obtained from the door lock is the most direct and accurate result, since the door lock is the performer of the unlocking action. Therefore, the mode that the door lock sends the unlocking success message or the unlocking failure message to the terminal equipment is adopted, so that a user can obtain a more accurate unlocking result, and the user experience is improved.

The embodiment of the application does not specifically limit the preset time, and the preset time can be determined according to time consumed by the door lock server for verifying whether the bound mobile phone number is consistent with the mobile phone number corresponding to the SIM card or not and time for the door lock server to send an unlocking instruction to the door lock. Considering that the calculation performance of the door lock server is not very low in general, the preset time may be a relatively small value, such as 10 seconds, 15 seconds, and the like, and of course, 10 seconds and 15 seconds are only shown for convenience of understanding and do not constitute a limitation on the embodiment of the present application.

As described above, in the embodiment of the present application, when a user corresponding to the user identifier is initially given an unlocking right to the door lock, the identifier of the door lock, the user identifier, and the mobile phone number of the user (that is, the binding mobile phone number) may be bound. The specific process of binding the identifier of the door lock, the user identifier and the binding mobile phone number is described in detail herein.

In this embodiment of the application, the user identifier corresponding to the account of the unlocking application program may include two types, where one type is an administrator user identifier, and the other type is a general user identifier. The account corresponding to the administrator user identifier may be user registered, and the account of the common user is allocated to the administrator user.

When the user identifier is an administrator user identifier, the mapping relationship among the user identifier, the door lock identifier and the binding mobile phone number may be, for example, when a user registers an account by using an unlocking application installed on a terminal device, the user identifier, the door lock identifier and the binding mobile phone number are bound. Specifically, a user may trigger an account registration operation on a terminal device, and the terminal device sends an account registration request to a door lock server based on the account registration operation, where the registration request includes the user identifier, the bound mobile phone number, and the identifier of the door lock. The door lock server stores the mapping relation among the user identification, the binding mobile phone number and the identification of the door lock according to the registration request, and can simultaneously send the mapping relation to a door lock end for storage.

When the user identifier is a common user identifier, the mapping relationship among the user identifier, the door lock identifier and the binding mobile phone number may be, for example, when a user corresponding to the administrator user identifier uses an unlocking application installed on the terminal device to allocate an account for the user corresponding to the user identifier, the door lock identifier and the binding mobile phone number are bound. Specifically, a user corresponding to the administrator user identifier may trigger a common account opening operation on the terminal device, and the terminal device sends a common account opening request to the door lock server based on the common account opening operation, where the common account opening request includes the user identifier, the bound mobile phone number, and the identifier of the door lock. And the door lock server saves the mapping relation among the user identification, the binding mobile phone number and the identification of the door lock according to the common account opening request. Correspondingly, the door lock server can also store the mapping relation between the administrator user identification and the user identification so as to verify the identity of the administrator user when the subsequent administrator user logs out the account corresponding to the user identification, and the door lock server can simultaneously send the mapping relation to the door lock end for storage.
