Example 1
Fig. 1 shows a schematic structural diagram of an intelligent door lock system according to an embodiment of the present invention.
The intelligent door lock system 100 includes a plurality of gateways 110 and a plurality of intelligent door locks 120, and each gateway 110 is connected to a plurality of intelligent door locks 120.
The gateway 110 is further connected to a server, the intelligent door lock 120 is connected to the server through the gateway 110, and the intelligent door lock 120 transmits stored door opening and closing information, lighting information, password information and the like to the server through the gateway 110, so that the server processes the information.
Further, the smart door lock 120 also stores water consumption information, electricity consumption information, gas consumption information, and the like of the resident in the smart door lock.
Specifically, the devices such as the electricity meter, the water meter, and the gas meter of the household and the smart door lock 120 form a local area network, the water consumption information, the electricity consumption information, and the gas consumption information of the household are transmitted to the smart door lock 120 for storage, and when the smart door lock 120 is in an awake state (for example, when the door is opened or closed), the data such as the water consumption information, the electricity consumption information, or the gas consumption information of the household can be transmitted to the server and/or the terminal where the household is located.
Further, the initial networking process of the intelligent door lock system 100 includes:
each gateway 110 scans the surrounding connectable smart locks 120 and establishes connections with all unpaired smart locks 120.
Specifically, before the intelligent door lock system 110 starts communication, a connection needs to be established between the gateway 110 and the intelligent door lock 120 in the intelligent door lock system 100.
Further, the "each gateway 110 scans the surrounding connectable smart locks 120 and establishes connections with all unpaired smart locks 120" includes:
each gateway 110 scans the surrounding connectable smart door locks 120 in each working frequency band and obtains the working state of the connectable smart door locks 120, wherein the working state includes an unpaired state and a paired state; each gateway 110 sends a networking request to all the intelligent door locks 120 which are scanned by the gateway and are in an unpaired state; the intelligent door lock 120 in the unpaired state, which receives the networking request, establishes a connection with the corresponding gateway 110, and sets the operating state of itself to the paired state.
Wherein, the connectable intelligent door lock 120 indicates that the gateway 110 can scan the signal sent by the intelligent door lock 120.
Specifically, each gateway 110 continuously adjusts its own working frequency band according to the divided working frequency bands, so that it scans whether there is an intelligent door lock 120 capable of performing connection in each working frequency band, and obtains the working states of the scanned intelligent door lock 120 capable of performing connection, where the working states include an unpaired state and a paired state.
The smart door lock 120 is in an unpaired state at initial setup. The smart door lock 120 is in an unpaired state when no connection is established with the gateway 110, and is in a paired state when a connection is established with the gateway 110.
Each gateway 110 integrates all the intelligent door locks 120 scanned in all the operating frequency bands, and determines the intelligent door lock 120 in an unpaired state.
Each gateway 110 sends a networking request to all the intelligent door locks 120 which are scanned by the gateway 110 and are in an unpaired state, and the intelligent door lock 120 which receives the networking request pairs with the gateway 110 according to a pairing signal in the networking request and establishes connection with the gateway 110 which sends the networking request.
After the connection is established, the intelligent door lock 120 also sets its own operating frequency band as the operating frequency band of the gateway 110 connected thereto, so that the intelligent door lock and the gateway 110 communicate with each other in the operating frequency band. The intelligent door lock 120 also changes the working state of the intelligent door lock from an unpaired state to a paired state, so that the intelligent door lock is prevented from receiving networking requests sent by other gateways 110 after establishing connection with the gateways 110, network resources are prevented from being wasted, and interference is reduced.
For example, as shown in fig. 2, an intelligent door lock in a residential building will be described as an example. The intelligent door locks A1-AM can be arranged on different floors of different buildings. The gateway A scans connectable intelligent door locks in each working frequency band, and sends networking requests to all intelligent door locks A1-AM in an unpaired state in all connectable intelligent door locks for connection. The intelligent door locks B1-BN can be arranged on different floors of different buildings. The gateway B scans the connectable intelligent door locks in each working frequency band, sends networking requests to all intelligent door locks B1-BN in an unpaired state in all the connectable intelligent door locks, and connects the connectable intelligent door locks until all the intelligent door locks are connected by all the gateways.
Specifically, at least one gateway 110 and a plurality of intelligent door locks 120 may be further installed in each floor of each building, signals sent by the intelligent door locks scanned by the gateway 110 include identity information, information of the located building and information of the located floor, and the gateway 110 identifies and establishes a connection with all the intelligent door locks 120 belonging to the same building and being in an unpaired state on the same floor. All the intelligent door locks 120 after establishing connection with the gateway 110 change the working state of the intelligent door locks from the unpaired state to the paired state.
For example, as shown in fig. 2, an intelligent door lock in a residential building will be described as an example. If the gateway A is installed on the 1 st floor of the building 1, the intelligent door locks A1-AM are installed on the 1 st floor of the building 1, and the intelligent door locks B1-BN are installed on the second floor of the building 1. Before networking, a gateway A scans connectable intelligent door locks A1-AM and B1-B3 in each working frequency band, all the intelligent door locks A1-AM installed on the first floor of a building 1 are screened out from all the connectable intelligent door locks through building information and floor information in signals sent by the intelligent door locks, the gateway A sends networking requests to the intelligent door locks A1-AM, the intelligent door locks A1-AM receiving the networking requests are paired with the gateway A according to pairing signals in the networking requests, and connection is established between the intelligent door locks A sending the networking requests and the gateway A. After connection is established, the intelligent door locks A1-AM change the working state of the intelligent door locks A1-AM from an unpaired state to a paired state so as to prevent other gateways from sending networking requests and reduce network resource occupation. Wherein M and N are integers greater than or equal to 2.
Specifically, it is also possible to install the gateway 110 and the plurality of intelligent door locks 120 in the building first from the first floor, the gateway 110 installed in the first floor scans all connectable intelligent door locks 120 in the first floor and establishes connection with the connectable intelligent door locks 120 in the unpaired state, and sets the operating states of all connected intelligent door locks to the paired state; after the networking of the first layer is finished, the gateway 110 and the plurality of intelligent door locks 120 may be installed in the second layer, the gateway 110 installed in the second layer scans all connectable intelligent door locks 120, all connectable intelligent door locks 120 scanned by the gateway 110 of the second layer may include the intelligent door lock installed in the second layer and the intelligent door lock installed in the first layer, since the operating state of the connected intelligent door lock installed in the first layer is the paired state, the gateway 110 installed in the second layer establishes a connection with the intelligent door lock 120 in the unpaired state among all connectable intelligent door locks 120 scanned, and sets the operating state of all connected intelligent door locks as the paired state; and sequentially installing networking layer by layer until the networking of the gateway 110 installed at the top layer and the intelligent door lock 120 installed at the top layer is finished.
For example, as shown in fig. 2, a three-layer network will be described as an example. The gateway A and the intelligent door locks A1-AM are installed on the first floor, and the intelligent door locks are in an unpaired state during installation. The gateway A scans the connectable intelligent door locks A1-AM in each working frequency band, and sends networking requests to all the intelligent door locks A1-AM in an unpaired state in all the connectable intelligent door locks for connection. After the connection is completed, the intelligent door locks A1-AM modify the working state of the intelligent door locks A1-AM from the unpaired state to the paired state.
And installing a gateway B and a plurality of intelligent door locks B1-BN on the second layer, wherein the intelligent door locks are in an unpaired state during installation. The gateway B scans the connectable intelligent door locks B1-BN and A1-A8 in each working frequency band, and sends networking requests to all the intelligent door locks B1-BN in an unpaired state in all the connectable intelligent door locks for connection. After connection is completed, the intelligent door locks B1-BN change the working state of the intelligent door locks from an unpaired state to a paired state.
And installing a gateway C and a plurality of intelligent door locks C1-CX on the third layer, wherein the intelligent door locks are in an unpaired state during installation. The gateway C scans the connectable intelligent door locks C1-CX, B1-B8 and A1-A4 in each working frequency band, and sends networking requests to all the intelligent door locks C1-CX which are in an unpaired state in all the connectable intelligent door locks to connect. After connection is completed, the intelligent door lock C1-CX modifies the working state of the intelligent door lock C1-CX from an unpaired state to a paired state. Wherein M, N and X are integers which are more than or equal to 2.
Before the intelligent door lock system 100 is initially networked, each gateway 110 is also used for determining an operating frequency band thereof.
Further, each gateway 110 scans whether there are other gateways 110 around, obtains the operating frequency bands of the other gateways 110, and sets its own operating frequency band according to the operating frequency bands of the other gateways 110.
Specifically, after power-on start and initialization of each gateway 110, actively scan whether there are other gateways 110 around in each operating frequency band, and if other gateways 110 are scanned, obtain the scanned operating frequency bands of other gateways 110, and set the operating frequency band of the gateway to be a different operating frequency band from that of other gateways 110 according to the operating frequency bands of other gateways 110.
For example, the working frequency range corresponding to the gateway 110 is determined according to the communication mode of the gateway 110, and the working frequency range is divided into a plurality of working frequency bands. If the gateway 110 and the smart door lock 120 communicate with each other in a Sub-1G wireless communication manner, the operating frequency range of the gateway 110 may be divided into 433MHz, 435MHz, 437MHz, 439MHz, and the like.
When the first gateway scans in each operating frequency band, if other surrounding gateways are not scanned, the operating frequency band of the first gateway may be set to 433 MHz. When the second gateway scans in each working frequency band, a connectable first gateway is scanned in a 433MHz frequency band, the working frequency band of the first gateway is acquired at 433MHz, and the working frequency band of the second gateway can be set to 435MHz according to the divided working frequency bands; when the third gateway scans in each working frequency band, a connectable first gateway is scanned in the 433MHz frequency band and a connectable second gateway is scanned in the 435MHz frequency band, the working frequency band of the first gateway is acquired at 433MHz and the working frequency band of the second gateway is acquired at 435MHz, and the working frequency band of the third gateway can be set to 437MHz according to the divided working frequency bands, and so on.
For another example, when the first gateway scans in each operating frequency band, if other surrounding gateways are not scanned, the operating frequency band of the first gateway may be set to 433 MHz. When the second gateway scans in each working frequency band, a connectable first gateway is scanned in the 433MHz frequency band, the working frequency band of the first gateway is acquired at 433MHz, and the working frequency band of the second gateway can be set to 437MHz according to the divided working frequency band; when the third gateway scans in each working frequency band, a connectable first gateway is scanned in the 433MHz frequency band and a connectable second gateway is scanned in the 437MHz frequency band, the working frequency band of the first gateway is acquired from 433MHz and the working frequency band of the second gateway is acquired from 437MHz, and the working frequency band of the third gateway can be set to 435MHz according to the divided working frequency bands, and so on.
When the connection with the current gateway 110 is dropped, the smart door lock 120 scans whether there is a connectable gateway 110 around.
Further, it is determined whether the connection with the current gateway 110 is dropped by:
the intelligent door lock 120 initiates a communication request to the current gateway 110 every preset time, and receives a reply signal sent by the current gateway 110 for the communication request; if the current gateway 110 does not receive the reply signal more than the predetermined number of times, the intelligent door lock 120 determines that the connection between the current gateway 110 and the intelligent door lock is disconnected.
Specifically, the intelligent door lock 120 sends a communication request signal (e.g., a heartbeat signal) to the current gateway 110 to which it is connected at preset intervals to determine whether the connection between the intelligent door lock and the current gateway 110 is dropped.
If the intelligent door lock 120 sends the communication request for the preset number of times and does not receive a reply signal returned by the current gateway 110 for the communication request, it is determined that the connection between the intelligent door lock 120 and the current gateway 110 is disconnected.
For example, if the intelligent door lock 120 sends the sequential communication request to the current gateway 110 every 1 second, the current gateway 110 returns a reply signal to the intelligent door lock 120 every time it receives the communication request. If the preset number of times is 30, the smart door lock 120 sends the communication request for 30 times, and does not receive the reply signal of the current gateway 110, and then it is determined that the connection between the smart door lock 120 and the current gateway 110 is disconnected.
Specifically, the connection between the intelligent door lock 120 and the current gateway 110 may be disconnected as follows:
the current gateway 110 is disconnected, and cannot be connected to the server and the intelligent door locks 120, in which case all the intelligent door locks 120 connected to the gateway 110 are disconnected from the current gateway 110. As shown in FIG. 2, if the gateway A is disconnected, the connections between the intelligent door locks A1-AM and the gateway A are all disconnected, wherein M is an integer greater than or equal to 2.
In this case, only the connection between the intelligent door lock 120 and the current gateway 110 is disconnected, and the connections between other intelligent door locks 120 connected to the current gateway 110 and the current gateway 110 are online. As shown in FIG. 2, the connection between the gateway B and the intelligent door lock B2 is disconnected, and the connection between the intelligent door lock B1, B3-BN and the gateway B can be online, wherein N is an integer greater than or equal to 2.
When the connection with the current gateway 110 is disconnected, the intelligent door lock 120 also scans whether signals sent by the connectable gateway 110 exist around each working frequency band, so that the intelligent door lock 120 is connected with the scanned connectable gateway 110, and the disconnection of the intelligent door lock is avoided.
If the connectable gateway 110 exists, the intelligent door lock 120 further sets the working frequency band of the intelligent door lock itself as the working frequency band of the connectable gateway 110, changes the working state of the intelligent door lock itself to an unpaired state, and sends a connection request to the connectable gateway 110.
For example, as shown in fig. 2, if the operating frequency band of the gateway a is 433MHz, the operating frequency band of the gateway B is 435 MHz. If the connection between the intelligent door lock A2 and the gateway A is disconnected, the intelligent door lock A2 scans the connectable gateway in each working frequency band, the connectable gateway B is scanned in the 435MHz working frequency band, and the intelligent door lock A2 does not scan other working frequency bands. The intelligent door lock A2 changes the working frequency band of the intelligent door lock A2 from 433MHz to 435MHz, changes the working state of the intelligent door lock A2 from a matched state to an unpaired state, and after the change is completed, the intelligent door lock A2 sends a connection request to the gateway B so that the intelligent door lock A2 can be connected to a server through the gateway B.
The connectable gateway 110 connects with the intelligent door lock 120 in an unpaired state according to the connection request, and stores the identity information of the connected intelligent door lock 120.
For example, as shown in fig. 2, after receiving the connection request sent by the intelligent door lock a2, the gateway B scans whether there is a connectable and unpaired intelligent door lock in the operating frequency band 435MHz where the gateway B is located, and if there is a connectable and unpaired intelligent door lock, the gateway B pairs with all connectable and unpaired intelligent door locks to initiate connection. After the intelligent door lock which can be connected and is in an unpaired state is successfully connected, the gateway B also records and stores the identity information of the connected intelligent door lock, wherein the identity information can be identity ID and the like.
For another example, as shown in fig. 2, after receiving the connection request sent by the intelligent door lock a2, the gateway B scans whether there is a connectable and unpaired intelligent door lock in the operating frequency band 435MHz where the gateway B is located, determines whether all connectable and unpaired intelligent door locks include the intelligent door lock a2 according to the ID in the connection request sent by the intelligent door lock a2 if there is a connectable and unpaired intelligent door lock, and pairs the gateway B with the intelligent door lock a2 if the intelligent door lock a2 is included, and initiates a connection. If the intelligent door lock A2 is not included, the gateway B does not initiate a pairing request. If no connectable intelligent door lock in an unpaired state is scanned, the gateway B does not initiate a pairing request.
After the connection with the intelligent door lock A2 is successful, the gateway B also records and stores the identity information of the intelligent door lock A2, wherein the identity information can be identity ID and the like.
Further, the "the connectable gateway 110 connects with the intelligent door lock 120 in the unpaired state according to the connection request" includes:
the connectable gateway 110 determines whether the number of all the intelligent door locks 120 connected thereto reaches a predetermined connection threshold value, and determines whether the communication quality between the connectable gateway 110 and the intelligent door locks 120 in the unpaired state reaches a predetermined quality threshold value; if the number of all the intelligent door locks 120 connected with the connectable gateway 110 does not reach the predetermined connection threshold value and the communication quality between the connectable gateway 110 and the intelligent door lock 120 in the unpaired state reaches the predetermined quality threshold value, the connectable gateway 110 establishes connection with the intelligent door lock 120 in the unpaired state.
Specifically, when the connectable gateway 110 connects to the intelligent door locks 120 in the unpaired state, it is further determined whether the number of all the intelligent door locks 120 connected to the connectable gateway 110 reaches a predetermined connection threshold (for example, the maximum allowable connection number), and whether the communication quality between the connectable gateway 110 and the intelligent door locks 120 in the unpaired state reaches a predetermined quality threshold, where the communication quality includes a communication success rate, a communication rate, a transmission power, a reception sensitivity, and the like.
If the number of all the intelligent door locks 120 connected to the connectable gateway 110 does not reach the predetermined connection threshold value, and the communication quality between the connectable gateway 110 and the intelligent door locks 120 in the unpaired state reaches the predetermined quality threshold value, it indicates that the number of the connected intelligent door locks 120 of the connectable gateway 110 is in the underfill state, the connectable gateway 110 may continue to connect to other intelligent door locks 120, and after the communication quality between the other intelligent door locks 120 to be connected and the connectable gateway 110 reaches the predetermined quality threshold value, the connectable gateway 110 establishes connection with the other intelligent door locks 120 in the unpaired state.
For example, as shown in fig. 2, taking a gateway a, a gateway B, and a gateway C as an example for explanation, if the operating frequency band of the gateway a is 433MHz, the operating frequency band of the gateway B is 435MHz, and the operating frequency band of the gateway C is 437 MHz.

After receiving the connection request sent by the intelligent door lock A2, the gateway B scans the operation frequency band of 435MHz, and after scanning the intelligent door lock A2 in an unpaired state, the gateway B judges whether the communication quality between the gateway B and the intelligent door lock A2 reaches a preset quality threshold value.
If the communication quality between the gateway B and the intelligent door lock A2 does not reach a preset quality threshold value, the gateway B does not establish connection with the intelligent door lock A2; if the communication quality between the gateway B and the intelligent door lock A2 reaches a preset quality threshold, the gateway B judges whether the number of the intelligent door locks connected with the gateway B reaches a preset connection threshold.
If the number of the intelligent door locks connected with the gateway B does not reach a preset connection threshold value, the connectable gateway B establishes connection with the intelligent door lock A2 in the unpaired state.
If the number of the intelligent door locks connected with the gateway B reaches a preset connection threshold value, the intelligent door lock A2 continuously scans whether connectable gateways exist in other working frequency bands, if the intelligent door lock A2 scans the connectable gateway C in the 437MHz working frequency band, the intelligent door lock A2 changes the working frequency band of the intelligent door lock A from 433MHz to 437MHz and changes the working state of the intelligent door lock A from a paired state to an unpaired state, and after the change is completed, the intelligent door lock A2 sends a connection request to the gateway C so that the intelligent door lock A can be connected to a server through the gateway C.
When the number of all the intelligent door locks C1-CX connected by the gateway C does not reach the preset connection threshold value and the communication quality between the gateway C and the intelligent door lock A2 in the unpaired state reaches the preset quality threshold value, the gateway C sends a pairing request to the intelligent door lock A2, and the intelligent door lock A2 completes pairing with the gateway C according to the pairing request and establishes connection with the gateway C.
Further, when the connection of the current gateway 110 is restored to the online state from the offline state, the current gateway 110 is reconnected to the originally paired intelligent door lock 120.
Further, the "the current gateway 110 reconnects with the originally paired intelligent door lock 120" includes:
the current gateway scans surrounding connectable gateways, sends the stored identity information of the originally paired intelligent door locks to the connectable gateways, and sets the working frequency band of the current gateway as the original working frequency band.
Further, the "current gateway scans connectable gateways around" includes:
the current gateway scans whether connectable gateways exist around each working frequency band; if the connectable gateway exists, the current gateway acquires the working frequency band of the connectable gateway, sets the working frequency band of the current gateway as the working frequency band of the connectable gateway, and performs data transmission with the corresponding connectable gateway in the set working frequency band.
Specifically, when the intelligent door lock and the current gateway are restored to the online state from the offline state, the current gateway firstly determines the working frequency band of the current gateway according to the scanned working frequency band of the connectable gateway, and sets the working frequency band of the current gateway as the scanned working frequency band of the connectable gateway, so as to perform data transmission with the corresponding connectable gateway in the set working frequency band.
After data transmission is carried out between the current gateway and the scanned connectable gateway, the current gateway sends the stored identity information of the originally paired intelligent door locks to the connectable gateway, so that the connectable gateway receiving the identity information of the originally paired intelligent door locks inquires whether the originally paired intelligent door locks exist in all the connected intelligent door locks.
And the identity information of the originally paired intelligent door locks is the identity information of all the intelligent door locks connected with the current gateway before the gateway is disconnected.
The current gateway sends the identity information of the original paired intelligent door lock to the connectable gateway, and then modifies the working frequency band of the current gateway into the original working frequency band, wherein the original working frequency band is the working frequency band before the disconnection.
And the connectable gateway judges whether the intelligent door lock related to the current gateway exists in the connected intelligent door locks according to the identity information of the originally paired intelligent door locks.
Specifically, the connectable gateway searches whether the originally paired intelligent door lock exists in all the connected intelligent door locks according to the received identity information of the originally paired intelligent door lock.
And if the intelligent door lock related to the current gateway exists, the connectable gateway sends a notification signal to the intelligent door lock related to the current gateway and disconnects the intelligent door lock related to the current gateway, and then the stored identity information of the intelligent door lock is updated according to the identity information of the disconnected intelligent door lock.

And updating the stored identity information of the intelligent door lock according to the disconnected intelligent door lock information, namely the identity information of all the intelligent door locks connected with the gateway only and stored in the gateway.
And after receiving the notification signal, the intelligent door lock related to the current gateway sets the working frequency band of the intelligent door lock to be the original working frequency band, changes the working state of the intelligent door lock to be an unpaired state, and sends a connection request to the current gateway.
Specifically, after receiving the notification signal sent by the connectable gateway, the originally paired intelligent door lock sets the working frequency band of itself from the working frequency band of the connectable gateway to the original working frequency band, changes the working state of itself from the paired state to the unpaired state, prepares for connection with the current gateway, and sends a connection request to the current gateway.
And after the current gateway establishes connection with the intelligent door lock in an unpaired state in the original working frequency band according to the connection request, and the identity information of the intelligent door lock connected with the current gateway is updated.
Specifically, the current gateway scans the intelligent door lock in the unpaired state in the original working frequency band where the current gateway is located according to the connection request, establishes connection with the intelligent door lock in the unpaired state, and updates the stored identity information of the intelligent door lock according to the newly connected intelligent door lock.

If the connection between A2 and gateway A is dropped, A2 connects to gateway C. When the connection between the A2 and the gateway A is restored to be on-line from off-line, the gateway A sets the working frequency band of the gateway A to be 435MHz of the working frequency band where the gateway B is located, sends the identity information of the original paired intelligent lock to the gateway B in the 435MHz working frequency band, sets the working frequency band of the gateway A to be 437MHz of the working frequency band where the gateway C is located, and sends the identity information of the original paired intelligent lock to the gateway C in the 437MHz working frequency band. After the gateway B searches the identity information of the intelligent door locks B1-BM stored by the gateway B according to the received identity information of the original paired intelligent locks, the original paired intelligent door locks are not found. After the gateway C searches for the identity information of the intelligent door locks C1-CX and A2 stored in the gateway C according to the received identity information of the original paired intelligent locks, the original paired intelligent door lock A2 is found, the gateway C sends a notification signal to the intelligent door lock A2 to notify the intelligent door lock A2 that the connection between the intelligent door lock A2 and the gateway A is on-line, the gateway C disconnects the connection between the intelligent door lock A2, and deletes the stored identity information of the intelligent door lock A2 connected with the gateway C.
After receiving the notification signal, the intelligent door lock a2 changes its working frequency band from 437MHz to 433MHz, changes its working state from a paired state to an unpaired state, and sends a connection request to the gateway a.
