Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, based on the embodiments herein, which a person of ordinary skill in the art would obtain without undue burden, are within the scope of protection of the present application.
For the convenience of understanding the technical solutions of the present application, first, related concepts related to the present application will be described:
Bluetooth is an open global specification for wireless data and voice communications, and is a wireless communication technology based on the IEEE802.11 standard protocol. The furthest communication distance between the two devices establishing bluetooth communication is 30 meters.
Because the transmission distance of the Bluetooth communication is short, the wireless Mesh network technology is considered to be introduced into Bluetooth to expand the network coverage range, namely, the Bluetooth Mesh network is formed. It should be emphasized here that bluetooth Mesh is not a wireless communication technology, but a networking technology. The relationship between Bluetooth and Bluetooth Mesh is: bluetooth Mesh networks rely on bluetooth technology, which is a wireless communication protocol stack used by bluetooth Mesh.
Next, the deployment characteristics of the bluetooth Mesh network will be described in detail.
The deployment mode of the bluetooth Mesh network is a gateway and a node (STA), namely, the bluetooth Mesh network is accessed to the network in a bluetooth mode, and the networking equipment comprises a bluetooth gateway and at least one STA. The Bluetooth gateway is a gateway device integrating Bluetooth, wiFi and Ethernet, data of the Bluetooth device connected with the Bluetooth gateway are transmitted to the server in a WiFi or Ethernet mode through the Bluetooth gateway through cross port between the Bluetooth and the WiFi, and data of the server side are transmitted back to the Bluetooth device. STA is a device in a bluetooth Mesh network that includes a bluetooth communication module. Therefore, the Bluetooth Mesh network is formed by a Bluetooth gateway and at least one piece of Internet of things equipment comprising the Bluetooth communication module, so that the Bluetooth Mesh network has the function of accessing an external network.
It should be noted that the bluetooth gateway may be a dedicated bluetooth gateway device, or may be a device including a bluetooth module and capable of being networked, for example, a device including a chip integrating the bluetooth module and the WiFi module.
In the Bluetooth Mesh network, based on the Bluetooth gateway construction, a plurality of STAs join a wireless network formed by the Bluetooth gateways. The networking mode is characterized in that: the Bluetooth gateway is used as the center of the whole Bluetooth Mesh network, other STAs establish Bluetooth communication with the Bluetooth gateway or establish Bluetooth communication with each other, so that the communication coverage range of the Bluetooth Mesh network is continuously extended.
Next, description is given of the prior art and problems existing in the prior art to which the present application relates:
in the related art, in the bluetooth Mesh network, generally only one device fixes a gateway device as the bluetooth Mesh network, wherein the gateway device is used to realize connection of the bluetooth Mesh network with an external network.
However, when the gateway device in the bluetooth Mesh network fails, the bluetooth Mesh network cannot access the external network, and can only be used as a local network, so that the problem of low reliability of the access of the bluetooth Mesh network to the external network exists.
Based on the above existing problems, the present application proposes the following technical concept: in a Bluetooth Mesh network composed of a plurality of pieces of equipment based on WiFi and Bluetooth Mesh dual-mode communication, because each piece of equipment is equipment based on WiFi and Bluetooth Mesh dual-mode communication, when part of pieces of equipment are connected with WiFi and accessed to the Bluetooth Mesh network at the same time, the part of equipment can serve as a gateway to be selected of the Bluetooth Mesh network. And selecting two pieces of Internet of things equipment from the part of Internet of things equipment to serve as a main gateway and a standby gateway of the Bluetooth Mesh network respectively. The main gateway of the Bluetooth Mesh network works as a gateway of the Bluetooth Mesh network; the standby gateway of the Bluetooth Mesh network is used as a candidate gateway in the Bluetooth Mesh network, and one STA used as the Bluetooth Mesh network can normally receive and send information during normal operation. When the main gateway of the Bluetooth Mesh network fails or the WiFi signal intensity is poor, the main gateway of the Bluetooth Mesh network stops working as the gateway of the Bluetooth Mesh network, and the standby gateway of the Bluetooth Mesh network is started to work as the gateway of the Bluetooth Mesh network, so that the connection between the Bluetooth Mesh network and an external network is smoothly realized. Therefore, the reliability of the Bluetooth Mesh network for accessing the external network is improved by arranging the master/slave gateway in the Bluetooth Mesh network.
Next, an application scenario of the embodiment of the present application will be described with reference to fig. 1.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. The application scene schematic diagram provided by the embodiment of the application comprises the following steps: the Bluetooth Mesh network comprises a WiFi router and a plurality of pieces of Internet of things equipment based on dual-mode communication, wherein the plurality of pieces of Internet of things equipment form the Bluetooth Mesh network. For simplicity of illustration, as shown in fig. 1, in the embodiment of the present application, the devices including 7 pieces of internet of things equipment based on dual-mode communication are respectively STA1, STA2, …, STA7, and the 7 pieces of internet of things equipment are devices based on WiFi and bluetooth Mesh dual-mode communication, that is, each device has a chip including a WiFi module and a bluetooth module. The STA1-STA7 are mutually connected to form a Bluetooth Mesh network, and the STA1, the STA2 and the STA3 are connected with the WiFi router.
It should be noted that, when the internet of things device based on WiFi and bluetooth Mesh dual mode communication is selected as the main gateway of the bluetooth Mesh network, data interaction can be performed between the WiFi module and the bluetooth Mesh module in the internet of things device when the internet of things device works as the gateway. When the device is used as non-gateway equipment, data interaction can not be performed between a WiFi module and a Bluetooth Mesh module in the device.
In the embodiment of the application, two pieces of internet of things equipment based on dual-mode communication are selected from 7 pieces of internet of things equipment based on dual-mode communication forming a Bluetooth Mesh network to serve as a main gateway and a standby gateway of the Bluetooth Mesh network respectively. The Bluetooth Mesh network is connected with the external network through the main gateway.
The technical scheme shown in the application is described in detail below through specific embodiments. It should be noted that the following embodiments may exist alone or in combination with each other, and the description will not be repeated in different embodiments for the same or similar contents.
Based on the technical concept described above, the method for deploying the active/standby gateway provided in the present application is described in detail below with reference to fig. 2 and a specific embodiment, and it should be noted that, an execution body in the embodiment of the present application is each device in the bluetooth Mesh network, and fig. 2 is a flowchart one of the method for deploying the active/standby gateway provided in the embodiment of the present application.
As shown in fig. 2, the method includes:
s201, the first device receives first messages sent by a plurality of second devices, wherein the first messages comprise device identifiers of the second devices, and the plurality of second devices are other devices except the first device.
A plurality of devices are included in the bluetooth Mesh network. Wherein the first device is one of a plurality of devices in the bluetooth Mesh network. The second device is other devices except the first device in the plurality of devices of the Bluetooth Mesh network.
In the embodiment, a plurality of devices in the Bluetooth Mesh network are all internet of things devices for dual-mode communication. Taking an internet of things device with dual-mode communication as an example of the internet of things device based on WiFi and Bluetooth Mesh communication, the method for deploying the master/standby gateway is described. Each device in the Bluetooth Mesh network mutually sends a first message corresponding to each other, wherein the first message comprises a device identifier of the device. For example, the device Identifier may be a Universal Unique Identifier (UUID) of the device. Wherein each device corresponds to a unique UUID and one UUID corresponds to a unique device. Thus, the UUID of a device may be referred to as an identification unique to that device.
Optionally, the first message further includes a WiFi signal strength of the device and the number of neighboring nodes. It should be noted that, whether the device has accessed to the WiFi network is determined according to the strength of the WiFi signal in the first message. For example, if the WiFi signal strength in the first message is 0, it indicates that the device is not connected to the WiFi network; if the WiFi signal strength in the first message is not 0, the device is indicated to be accessed to the WiFi network. In addition, the stronger the WiFi signal strength in the first message, the better the WiFi network state of the device is indicated.
The first device receives first messages sent by a plurality of second devices. For example, through a bluetooth Mesh network, a first device receives a first packet sent by other devices in the bluetooth Mesh network. Specifically, when the first device is directly connected with a part of devices, the first device directly receives a first message sent by other devices; when the first device is not directly connected with other part of devices, the device between the first device and the other part of devices is used as a relay device to realize that the other part of devices send the first message to the first device, so that the first device receives the first message sent by the other part of devices.
S202, the first device judges whether the first device is a master gateway of the Bluetooth Mesh network.
Next, two possible implementations of the first device determining whether the first device is a primary gateway of the bluetooth Mesh network are exemplarily described.
In one possible implementation, the first device determines, according to configuration information of the primary gateway, whether the first device is a primary gateway of the bluetooth Mesh network. The configuration information may be, for example, a UUID of the device. Specifically, whether the first device is the main gateway of the bluetooth Mesh network is determined by judging whether the UUID of the first device is consistent with the UUID of the device corresponding to the main gateway of the bluetooth Mesh network. Under the condition, when the UUID of the first device is consistent with the UUID of the device corresponding to the main gateway of the Bluetooth Mesh network, determining that the first device is the main gateway of the Bluetooth Mesh network; in another case, when the UUID of the first device is inconsistent with the UUID of the device corresponding to the main gateway of the bluetooth Mesh network, it is determined that the first device is not the main gateway of the bluetooth Mesh network.
In another possible implementation manner, the first device determines whether the first device is a primary gateway of the bluetooth Mesh network according to the WiFi signal strength in the first messages sent by the plurality of second devices. The first message includes the strength of the WiFi signal. Specifically, according to the intensity of the WiFi signals in the first messages of the plurality of devices, the device corresponding to the maximum WiFi signal intensity in the first messages is determined to be the main gateway of the Bluetooth Mesh network. If the WiFi signal intensity corresponding to the first device is the device with the maximum WiFi signal intensity in the plurality of devices, the first device can determine that the first device is a main gateway, otherwise, the first device is determined not to be the main gateway of the Bluetooth Mesh network.
In this embodiment, only the specific implementation manner of determining, by the first device, whether the first device is the primary gateway of the bluetooth Mesh network is described as an example, but not limited, and the specific implementation manner of determining, by the first device, whether the first device is the primary gateway of the bluetooth Mesh network may be selected according to actual requirements.
And S203, if the first equipment is a main gateway, the first equipment determines a standby gateway of the Bluetooth Mesh network in the plurality of second equipment according to the first messages sent by the plurality of second equipment, and sends the equipment identification of the main gateway and the equipment identification of the standby gateway to the plurality of second equipment.
In a practical embodiment, when the first device determines that the first device is a primary gateway of the bluetooth Mesh network, the first device determines a backup gateway of the bluetooth Mesh network in a plurality of second devices according to first messages sent by a plurality of devices of the bluetooth Mesh network.
Next, two possible implementation methods of determining the backup gateway of the bluetooth Mesh network in the plurality of second devices according to the first messages sent by the plurality of devices of the bluetooth Mesh network by the first device are exemplarily described.
In one possible implementation, when the first device determines that the first device is a primary gateway of the bluetooth Mesh network according to the configuration information, then the first device determines a backup gateway of the bluetooth Mesh network according to WiFi signal intensities in first messages sent by the plurality of second devices. Specifically, according to the intensity of the WiFi signals in the first messages of the plurality of devices, the device corresponding to the maximum WiFi signal intensity in the first messages is determined to be a standby gateway of the Bluetooth Mesh network.
In another possible implementation manner, when the first device is determined that the first device is the primary gateway of the bluetooth Mesh network according to the first device being the device corresponding to the maximum WiFi signal strength in the bluetooth Mesh network, the first device determines that the WiFi signal strength in the first messages sent by the plurality of second devices in the bluetooth Mesh network is located in the second device, and determines that the first device is the backup gateway of the bluetooth Mesh network.
After the first device determines the backup gateway of the Bluetooth Mesh network in the plurality of second devices, the first device sends the device identifier corresponding to the Bluetooth Mesh master gateway device and the device identifier corresponding to the backup gateway device to the plurality of second devices in the Bluetooth Mesh network.
The method for deploying the master/slave gateway is applied to a Bluetooth Mesh network, wherein the Bluetooth Mesh network comprises a plurality of devices and comprises the following steps: the first device receives a first message sent by a plurality of second devices, wherein the first message comprises device identifiers of the second devices, and the plurality of second devices are other devices except the first device in the plurality of devices. The first device judges whether the first device is a master gateway of the Bluetooth Mesh network. If the first device is a main gateway, the first device determines a standby gateway of the Bluetooth Mesh network in the plurality of second devices according to the first messages sent by the plurality of second devices, and sends the device identification of the main gateway and the device identification of the standby gateway to the plurality of second devices. The main gateway and the standby gateway are simultaneously arranged in the Bluetooth Mesh network, so that the reliability of the Bluetooth Mesh network in accessing to the external network is improved.
On the basis of the above embodiments, the primary and backup gateway deployment methods provided in the present application are further described below in conjunction with a specific embodiment, and are described in conjunction with fig. 3, where fig. 3 is a flow chart two of the primary and backup gateway deployment method provided in the embodiment of the present application.
As shown in fig. 3, the method includes:
s301, a first device receives a first message sent by a plurality of second devices, wherein the first message comprises device identifiers of the second devices, and the plurality of second devices are other devices except the first device in the plurality of devices.
The implementation of step S301 is similar to that of step S201, and will not be described here again.
S302, the first device judges whether the first device is a main gateway of the Bluetooth Mesh network, and if yes, S303 is executed.
Next, two possible implementations of the first device determining whether the first device is a primary gateway of the bluetooth Mesh network are exemplarily described.
In one possible implementation, the first device determines, according to configuration information of the primary gateway, whether the first device is a primary gateway of the bluetooth Mesh network. The configuration information may be, for example, a UUID of the device. Specifically, whether the first device is the main gateway of the bluetooth Mesh network is determined by judging whether the UUID of the first device is consistent with the UUID of the device corresponding to the main gateway of the bluetooth Mesh network. Under the condition, when the UUID of the first device is consistent with the UUID of the device corresponding to the main gateway of the Bluetooth Mesh network, determining that the first device is the main gateway of the Bluetooth Mesh network; in another case, when the UUID of the first device is inconsistent with the UUID of the device corresponding to the main gateway of the bluetooth Mesh network, it is determined that the first device is not the main gateway of the bluetooth Mesh network.
In another possible implementation manner, the first message further includes the WiFi signal strength and the number of neighboring nodes of the second device. The first device judges whether the first device is a main gateway of the Bluetooth Mesh network according to the WiFi signal intensity and the number of neighbor nodes in the first messages sent by the second devices. Specifically, the first device determines at least one third device from among the first device and the plurality of second devices according to the WiFi signal strength of each second device and the WiFi signal strength of the first device. The at least one third device is the device with the highest WiFi signal intensity in the first device and the plurality of second devices. The first device determines whether the first device is included in the at least one third device. If the first device is not included in the at least one third device, it is determined that the first device is not the primary gateway. If the at least one third device comprises the first device, judging whether the number of neighbor nodes corresponding to the first device is larger than the number of neighbor nodes corresponding to other devices in the at least one third device; if the number of the neighbor nodes corresponding to the first equipment is larger than the number of the neighbor nodes corresponding to other equipment in at least one third equipment, determining that the first equipment is a main gateway; and if the number of the neighbor nodes corresponding to the first device is smaller than or equal to the number of the neighbor nodes corresponding to other devices in at least one third device, determining that the first device is not the primary gateway.
S303, the first device determines at least one fourth device from the plurality of second devices according to the WiFi signal intensity of each second device, wherein the fourth device is the device with the highest WiFi signal intensity from the plurality of second devices.
After the first device determines that the first device is the primary gateway of the bluetooth Mesh network based on the above step S302, the first device determines the backup gateway of the bluetooth Mesh network according to steps S303-S309.
In this embodiment, the first device determines, according to the WiFi signal strengths of the second devices, a device corresponding to the maximum WiFi signal strength among the plurality of second devices as a fourth device. Wherein the number of fourth devices is at least one.
S304, the first device judges whether the number of the fourth devices is 1, if yes, S305 is executed, and if not, S306 is executed.
In this embodiment, the first device determines a backup gateway of the bluetooth Mesh network according to the number of fourth devices.
S305, the first device determines at least one fourth device as a standby gateway.
In the embodiment, when the first device determines that the number of the fourth devices is 1, it is indicated that the WiFi signal strength corresponding to the fourth device is the only maximum of the WiFi signal strengths of the plurality of second devices. Thus, the fourth device is determined to be a backup gateway of the bluetooth Mesh network.
S306, the first device determines at least one fifth device in the at least one fourth device according to the number of neighbor nodes of each fourth device, wherein the fifth device is the device with the largest number of neighbor nodes in the at least one fourth device.
In the embodiment, when the first device determines that the number of the fourth devices is not 1, it indicates that the WiFi signal intensities corresponding to the fourth devices are the maximum WiFi signal intensities in parallel among the WiFi signal intensities of the second devices.
And then, the first device determines the standby gateway of the Bluetooth Mesh network in the fourth devices according to the number of the neighbor nodes of each fourth device. Wherein, the neighboring node may further include: primary neighbor nodes, secondary neighbor nodes, tertiary neighbor nodes, etc. The corresponding number of neighbor nodes may include: the number of the primary neighbor nodes, the number of the secondary neighbor nodes, the number of the tertiary neighbor nodes and the like.
In one possible implementation, for example, the standby gateway of the bluetooth Mesh network is determined mainly by the number of primary neighbor nodes. Those skilled in the art will appreciate that the greater the number of primary neighbor nodes of a device, the closer the device is to the center of the bluetooth Mesh network. And the first device determines the device with the largest number of the first-level neighbor nodes in the fourth devices as the fifth device according to the number of the first-level neighbor nodes in the fourth devices. Wherein the number of fifth devices is at least one.
S307, the first device judges whether the number of the fifth devices is 1, if yes, the S308 is executed, and if not, the S309 is executed.
Based on step S306, after the first device determines at least one fifth device among the at least one fourth device, the first device next determines a backup gateway of the bluetooth Mesh network according to the number of the fifth devices.
S308, the first device determines at least one fifth device as a standby gateway.
In the embodiment, when the first device determines that the number of the fifth devices is 1, it is indicated that the number of the first-stage neighbor nodes corresponding to the fifth devices is the only maximum number of the first-stage neighbor nodes of the plurality of second devices. Thus, the fifth device is determined to be a backup gateway of the bluetooth Mesh network.
S309, the first device determines the device with the smallest device identifier in the at least one fifth device as the standby gateway.
The device identity is a fixed length value, e.g. the device identity may be a UUID.
In the embodiment, when the first device determines that the number of the fifth devices is not 1, it indicates that the number of the first-stage neighbor nodes corresponding to the plurality of fifth devices is the largest parallel among the number of the first-stage neighbor nodes of the plurality of fourth devices.
And then, the first device determines a standby gateway of the Bluetooth Mesh network in a plurality of fifth devices according to the device identification of each fifth device. Taking the example that the device identifier is a UUID, the first device determines a device corresponding to the smallest UUID in the plurality of fifth devices as a backup gateway of the bluetooth Mesh network.
S310, the first device sends the device identification of the main gateway and the device identification of the standby gateway to a plurality of second devices.
After the first device determines the main gateway and the standby gateway of the bluetooth Mesh network based on the steps, the first device sends the device identification of the main gateway and the device identification of the standby gateway to a plurality of second devices in the bluetooth Mesh network. The device identifier may be a UUID, for example. Taking the device identifier as a UUID as an example, the first device sends UUIDs of a main gateway and UUIDs of a standby gateway of the Bluetooth Mesh network to a plurality of second devices.
It should be noted that, the standby gateway needs to store the same bluetooth Mesh network node information as the main gateway, and needs to subscribe the same bluetooth Mesh network node application as the main gateway, which is favorable for seamlessly switching the standby gateway into the main network management to work when the standby gateway needs to be switched into the main gateway to work.
The method for deploying the master/slave gateway provided by the embodiment of the application comprises the following steps: the first device receives a first message sent by a plurality of second devices, wherein the first message comprises device identifiers of the second devices, and the plurality of second devices are other devices except the first device in the plurality of devices. The first device judges whether the first device is a master gateway of the Bluetooth Mesh network. If the first device is a main gateway, the first device determines at least one fourth device in the plurality of second devices according to the WiFi signal intensity of each second device, and the fourth device is the device with the maximum WiFi signal intensity in the plurality of second devices. The first device determines whether the number of fourth devices is 1. If yes, the first device determines at least one fourth device as a backup gateway. If not, the first device determines at least one fifth device in the at least one fourth device according to the number of neighbor nodes of each fourth device, wherein the fifth device is the device with the largest number of neighbor nodes in the at least one fourth device. The first device determines whether the number of fifth devices is 1. If yes, the first device determines at least one fifth device as a backup gateway. If not, the first device determines the device with the smallest device identifier in the at least one fifth device as the backup gateway. The first device sends the device identification of the primary gateway and the device identification of the backup gateway to the plurality of second devices. The method for determining the main gateway and the standby gateway in the Bluetooth Mesh network according to the WiFi signal intensity, the number of neighbor nodes and the device identification of a plurality of devices in the Bluetooth Mesh network ensures the WiFi communication quality of the main gateway and the standby gateway in the Bluetooth Mesh network, and simultaneously ensures that the main gateway and the standby gateway are closer to the center of the network, so that unnecessary communication overhead can be reduced.
On the basis of the above embodiment, in order to ensure that the bluetooth Mesh network can normally access the external network, it is necessary to determine whether the primary gateway in the bluetooth Mesh network needs to be switched according to the WiFi signal strength of the first device.

If not, the standby gateway of the Bluetooth Mesh network needs to be updated.

In the embodiment, when the first device determines that the WiFi signal strength corresponding to the first device is smaller than the first threshold, it indicates that the WiFi signal strength of the first device is smaller, and reliability of the bluetooth Mesh network in accessing to the external network cannot be guaranteed. Therefore, the main gateway needs to be stopped, and the standby gateway needs to be operated as a gateway of the bluetooth Mesh.
In one possible implementation, the first device sends a primary and backup gateway switching instruction to the backup gateway. The master/slave gateway switching instruction is used for indicating to switch the slave gateway to the master gateway.

After the updating is completed, the first device is updated to the switched main gateway, namely the main gateway for indicating the Bluetooth Mesh.
S405, the first device sends a status information request to the plurality of second devices.
In the embodiment, when the first device determines that the standby gateway needs to be updated, the first device sends state information requests to a plurality of second devices in the bluetooth Mesh network to acquire the state information requests of the second devices. Wherein the status information includes: wiFi signal strength, number of neighbor nodes, etc., are not limited.

The method for deploying the master/slave gateway provided by the embodiment of the application comprises the following steps: the first device judges whether the WiFi signal strength corresponding to the first device is larger than or equal to a first threshold value. The first device judges whether the WiFi signal strength corresponding to the standby gateway is larger than or equal to a second threshold value. If not, the first device sends a status information request to the plurality of second devices.

And according to the second messages sent by the plurality of second devices, the first device updates the standby gateway of the Bluetooth Mesh network. Whether the backup gateway needs to be updated is determined according to the WiFi signal intensity of the backup gateway in the Bluetooth Mesh network, so that the effectiveness of the master backup gateway is ensured, and the reliability of the Bluetooth Mesh network in accessing to the external network is further improved.
