Description

Bluetooth networking method and system

Technical Field

The invention relates to the field of wireless communication, in particular to a Bluetooth networking method and a Bluetooth networking system.

Background

Bluetooth, as a short-range wireless connection technology, establishes a special connection for the fixed and mobile device communication environments based on low-cost short-range wireless connection, and can implement convenient, fast, flexible, safe, low-cost, low-power consumption data communication and voice communication between devices, so it is one of the mainstream technologies currently implementing wireless personal area network communication.

Compared with the traditional Bluetooth (BT for short), the Bluetooth (BLE) with Low power consumption has the advantages of fast search, fast connection and ultra-Low power consumption, and connection and data transmission are kept. Bluetooth low energy has been widely used since its self-introduction.

Establishing a bluetooth connection is a necessary condition for data transmission, and the networking modes based on the bluetooth low energy in the prior art include a point-to-point networking mode adopting a star structure and a mesh networking mode using a mesh topology structure. When a star-structured peer-to-peer networking mode is adopted, 1 Bluetooth master device can only be connected with 7 Bluetooth slave devices, and communicates with 7 slave devices in a polling mode to form a Bluetooth piconet. The networking mode severely limits the number of networking devices and communication distance, and the polling mode also causes low data communication efficiency.

When a mesh networking mode of a mesh topology structure is used, a plurality of modules can be simply added into the network, each network can be connected with more than 65000 equipment nodes by using a star network and a relay technology, each equipment node can freely communicate with other nodes, and the network can be interconnected. Although the communication distance is far longer than that of a piconet, a mesh network based on a mesh topology structure adopts a method of connecting more bluetooth devices, so that a complex network access process exists, the communication data volume of nodes is large, the real-time performance of data is poor, and the subsequent maintenance is difficult.

Therefore, how to provide a bluetooth networking method and system, so as to reduce the complexity of the processing flow of the bluetooth device and improve the real-time performance of bluetooth data transmission, is a problem to be solved urgently.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a flowchart of a bluetooth networking method according to an embodiment of the present invention, and as shown in fig. 1, the bluetooth networking method according to the embodiment of the present invention is applied to a bluetooth base station, and the method includes:

step S1, acquiring a unique mark of a first Bluetooth device to be networked, and adding the unique mark of the first Bluetooth device to be networked into a first queue, wherein the first queue is used for recording the unique mark of the first Bluetooth device to be networked;

step S2, selecting second Bluetooth devices from the first queue according to a preset number, generating a first broadcast message according to the unique identifier of the selected second Bluetooth devices and the mac address of the Bluetooth base station, and broadcasting the first broadcast message; after receiving the first broadcast message, the Bluetooth device compares whether the first broadcast message has a corresponding unique mark;

step S3, receiving an already-accessed broadcast message replied by a second bluetooth device, determining that the second bluetooth device has already accessed, and removing the unique identifier of the already-accessed second bluetooth device from the first queue.

Specifically, in step S1, the bluetooth base station acquires the mac address of the first bluetooth device to be networked through the internet, and adds the last 3 bytes of the mac address of the first bluetooth device as the unique identifier of the bluetooth device into the first queue.

The bluetooth mac address is composed of 6 bytes (48 bits long), 16-ary digits, the first 3 bytes (0-23 bits) are assigned by the bluetooth manufacturer, and the last 3 bytes (24-47 bits) are used to identify the node id of the LAN (local area network) to ensure the distinction between individuals. Therefore, because the bytes of the broadcast are limited by bytes, the last 3 bytes of the mac address of the bluetooth device are taken as the unique mark of the bluetooth device, the loading amount of effective information during broadcasting can be effectively increased, and the transmission amount and the transmission times of data are reduced.

It should be noted that, in this embodiment, the unique identifier of the bluetooth device is the last 3 bytes of the mac address of the bluetooth device, and in practical application, other data may also be used as the unique identifier of the bluetooth device, which is not limited in this embodiment.

In step S2, the bluetooth base station selects second bluetooth devices from the first queue according to a preset number, and generates and broadcasts a first broadcast message according to the unique identifier of the selected second bluetooth device and the mac address of the bluetooth base station; after receiving the first broadcast message, the bluetooth device compares whether the first broadcast message has the unique mark corresponding to the bluetooth device.

Specifically, for example, the first queue has a total of 20 unique identifiers of the first bluetooth devices, and at this time, the bluetooth base station adopts an algorithm of queue sorting, selects 7 bluetooth devices in the first queue in order as the second bluetooth devices, and uses the unique identifiers of the 7 second bluetooth devices and the mac addresses of the bluetooth base station as the first broadcast message.

It should be noted that, in the embodiment of the present invention, the bluetooth protocol used is a bluetooth BLE4.2 protocol, and for the purpose of interconnection, the BLE4.2 protocol defines a detailed format for broadcast Data and scan response Data of 31 bytes, and one broadcast Data packet is composed of six parts, namely Len, ADType, Random, iden, cmd, and Data.

Because the maximum Data information which can be carried by one broadcast message in the protocol is 26 bytes, when the last 3 bytes of the mac address of the Bluetooth device are used as the unique mark of the Bluetooth device, the broadcast can carry the unique marks of 8 Bluetooth devices at most at the same time.

It should be noted that, in the embodiment of the present invention, in the first broadcast message, the Data information only carries the unique identifier of the bluetooth device, and the mac address of the bluetooth base station is carried by the bluetooth protocol layer, which does not need to be carried by the Data information.

However, in an actual use situation, other bluetooth protocols such as the bluetooth BLE5.0 protocol may be used, or other data may be used as the unique identifier of the bluetooth device, so that the number of the unique identifiers of the bluetooth devices that can be carried at most at one time in one broadcast may be adjusted according to the actual situation, and meanwhile, the number of the bluetooth devices in the network entry queue, the frequency and duration of broadcast transmission may all be adjusted according to the actual situation, which is not limited in this embodiment.

On the basis, Random numbers can be added in the broadcast messages, when the Bluetooth equipment receiving the broadcast messages finds that the Random numbers in the continuous broadcast messages are the same, only one piece of information is processed, the Bluetooth equipment is ensured to process the same broadcast message only once, the same broadcast message is prevented from being processed repeatedly, and the complexity of the processing flow of the Bluetooth equipment is reduced.

In step S3, the bluetooth base station receives the returned broadcast message of network access from the second bluetooth device, determines that the second bluetooth device has network access, and removes the unique identifier of the second bluetooth device that has network access determined from the first queue.

The embodiment of the invention provides a Bluetooth networking method, which adopts a mode of active inquiry of a Bluetooth base station and passive response of Bluetooth equipment, and is different from a scheme that a request and a reply are required in four steps of connection establishment, connection request, connection establishment and connection disconnection in the traditional Bluetooth connection process. The interactive flow between the Bluetooth base station and the Bluetooth equipment can be effectively reduced, data transmission is carried out through the unique mark of the Bluetooth, the transmission quantity of data can be effectively reduced, the complexity of the processing flow of the Bluetooth equipment is reduced, and the real-time performance of Bluetooth data transmission is improved.

Based on the above embodiment, optionally, the bluetooth networking method further includes:

Specifically, in order to enable the bluetooth device to receive the broadcast, the bluetooth base station may continuously broadcast the first broadcast message for a period of time, so that after the bluetooth device receives the first broadcast message, the bluetooth base station may compare whether there is a unique identifier corresponding to the bluetooth base station in the first broadcast message. The time that the Bluetooth base station continuously broadcasts is taken as a first period.

After the Bluetooth device accesses the network, the Bluetooth device feeds back the accessed broadcast message to the Bluetooth base station, so that the Bluetooth base station can determine that the Bluetooth device accesses the network. And when the network-accessed broadcast message replied by the second Bluetooth equipment is not received in the first period, the Bluetooth base station determines that the second Bluetooth equipment is not accessed to the network and moves the unique mark of the second Bluetooth equipment which is determined not to be accessed to the tail of the first queue. In the process of circularly selecting the Bluetooth devices in the first queue, the Bluetooth devices at the end of the first queue are selected again.

For example, the first queue has a total of 20 unique identifiers of the first bluetooth devices, and at this time, the bluetooth base station adopts an algorithm for queue sorting, and in step a, the unique identifiers of 7 second bluetooth devices and the mac address of the bluetooth base station are arbitrarily selected as the first broadcast message, and the broadcast is continuously performed for 0.5s at a frequency of transmitting once every 100 ms. The time 0.5s that the bluetooth base station continuously broadcasts at this time is taken as the first period.

If 7 second bluetooth devices in the first period, 4 broadcast messages which are accessed to the network are fed back to the bluetooth base station. The bluetooth base station removes the unique identifiers of the 4 bluetooth devices from the first queue. The unique identifiers of the other 3 bluetooth devices are moved to the end of the first queue.

When it needs to be described, in this embodiment, when the first bluetooth device with the preset number in the first queue is selected as the second bluetooth device, the queue sorting algorithm is adopted. The unique identifiers of all bluetooth devices in the first queue are processed in sequence. In a specific application, the method may also be random selection, or reverse selection, which is not limited in this embodiment.

The embodiment of the invention provides a Bluetooth networking method, which adopts a mode of active inquiry of a Bluetooth base station and passive response of Bluetooth equipment, and is different from a scheme that a request and a reply are required in four steps of connection establishment, connection request, connection establishment and connection disconnection in the traditional Bluetooth connection process. The interactive flow between the Bluetooth base station and the Bluetooth equipment can be effectively reduced, data transmission is carried out through the unique mark of the Bluetooth, the transmission quantity of data can be effectively reduced, the complexity of the processing flow of the Bluetooth equipment is reduced, and the real-time performance of Bluetooth data transmission is improved. The Bluetooth base station adopts the algorithm of queue sequencing, so that the condition that fewer broadcasts exist in the environment can be effectively ensured, the possibility of Bluetooth broadcast conflict is reduced, and the effective network access of Bluetooth equipment is ensured.

Specifically, in the process of continuously selecting the first bluetooth device in the first queue as the second bluetooth device, broadcasting the unique identifier of the second bluetooth device, and removing the unique identifier of the bluetooth device to be networked from the first queue, the unique identifier of the first bluetooth device stored in the first queue is less and less.

And the Bluetooth base station needs to judge whether the first queue is an empty queue, and when the first queue is not the empty queue, the Bluetooth base station re-executes the steps of selecting second Bluetooth equipment from the first queue according to the preset number, generating a first broadcast message according to the unique mark of the selected second Bluetooth equipment and the mac address of the Bluetooth base station, and broadcasting the first broadcast message.

If the first queue is judged to be an empty queue, the fact that all the Bluetooth devices with access networks in the first queue have access networks is shown.

It should be noted that, since the transmission process of bluetooth is affected by obstacles, there may be a case that an individual bluetooth device cannot always access the network, and on the basis of the above embodiment, it is possible to set a response time threshold to control whether broadcasting still needs to be continued. For example, the response time threshold for 20 bluetooth devices to be networked is set to 5min, and the time 0.5s for which the bluetooth base station continuously broadcasts is taken as the first period. And after 10 first periods, the Bluetooth equipment still cannot access the network, judging that the response of the Bluetooth equipment is overtime, and abandoning to continue broadcasting.

The embodiment of the invention provides a Bluetooth networking method, which adopts a mode of active inquiry of a Bluetooth base station and passive response of Bluetooth equipment, and is different from a scheme that a request and a reply are required in four steps of connection establishment, connection request, connection establishment and connection disconnection in the traditional Bluetooth connection process. The method can effectively reduce the interactive flow between the Bluetooth base station and the Bluetooth equipment in the process of accessing the network of the Bluetooth equipment, and transmits data by using the unique mark of the Bluetooth, thereby effectively reducing the transmission quantity of data, reducing the complexity of the processing flow of the Bluetooth equipment and improving the real-time performance of Bluetooth data transmission.

Specifically, the bluetooth base station adds the unique identifier and the corresponding packet number, which are acquired through the internet and are required to be grouped into the third bluetooth device, into the second queue.

Selecting fourth Bluetooth equipment from the second queue according to a preset number, generating a second broadcast message according to the unique mark of the selected fourth Bluetooth equipment and the corresponding packet number, and broadcasting the second broadcast message; after receiving the second broadcast message, the bluetooth device compares whether the second broadcast message has the unique mark corresponding to the bluetooth device.

And when the Bluetooth equipment finds that the second broadcast message comprises the unique mark corresponding to the Bluetooth equipment, grouping according to the grouping number corresponding to the unique mark of the Bluetooth equipment, and feeding back the grouped broadcast message to the Bluetooth base station.

And the Bluetooth base station receives the grouped broadcast message replied by the fourth Bluetooth device, determines that the fourth Bluetooth device is grouped, and removes the unique mark of the grouped fourth Bluetooth device and the corresponding group number from the second queue.

And taking the duration of the same broadcast message sent by the Bluetooth base station as a second period, and if the Bluetooth base station does not receive the grouped broadcast message replied by the fourth Bluetooth device in the second period, moving the group number corresponding to the unique mark of the fourth Bluetooth device to the tail of the second queue.

After the second period is carried out once, the Bluetooth base station judges whether the second queue is an empty queue, when the second queue is not the empty queue, the steps of selecting fourth Bluetooth equipment from the second queue according to the preset number, generating a second broadcast message according to the packet number corresponding to the unique mark of the selected fourth Bluetooth equipment, and broadcasting the second broadcast message are carried out again. Or the bluetooth device that still does not implement the packet is deemed to react to a timeout and forgo continuing the broadcast.

And if the Bluetooth base station finds that the second queue is empty, judging that all the third Bluetooth devices needing grouping in the second queue are completely grouped, and stopping continuing broadcasting.

It should be noted that, in the embodiment of the present invention, the number of unique tags of bluetooth devices that can be carried at most at the same time in one broadcast may be adjusted according to the actual situation, and meanwhile, the number of bluetooth devices in a packet queue, the frequency and the duration of broadcast transmission may all be adjusted according to the actual situation, which is not limited in this embodiment.

The embodiment of the invention provides a Bluetooth networking method, which adopts a mode of active inquiry of a Bluetooth base station and passive response of Bluetooth equipment, and is different from a scheme that a request and a reply are required in four steps of connection establishment, connection request, connection establishment and connection disconnection in the traditional Bluetooth connection process.

The bluetooth base station adopts the algorithm of queue sequencing, can effectively guarantee that the broadcasting that exists is less in the environment, reduces the possibility of bluetooth broadcast conflict, guarantees the quick effectual network access of bluetooth equipment and packetizes, realizes the management to bluetooth equipment data transmission, adds the function that realizes that multiunit bluetooth equipment receives different broadcast messages, improves the flexibility that bluetooth equipment used.

Specifically, after the bluetooth device is networked, the networked bluetooth device can be disconnected, and the bluetooth base station acquires the unique mark of the fifth bluetooth device needing to be disconnected through the internet and joins the third queue.

And selecting a preset number of Bluetooth devices from the third queue as sixth Bluetooth devices, generating a third broadcast message according to the sixth Bluetooth devices and the network quitting instruction, and sending the third broadcast message.

In order to enable the Bluetooth device to receive the broadcast, the Bluetooth base station continuously broadcasts a third broadcast message for a period of time, so that the Bluetooth device compares whether the third broadcast message has a corresponding unique mark or not after receiving the third broadcast message; the duration of continuously sending the third broadcast message is a third period.

And when the Bluetooth equipment finds that the third broadcast message comprises the unique mark corresponding to the Bluetooth equipment, feeding back the network quitting broadcast message to the Bluetooth base station and quitting the network.

And the Bluetooth base station receives the broadcast message of the network quitting replied by the sixth Bluetooth equipment, determines that the sixth Bluetooth equipment has quitted the network, and removes the unique mark of the sixth Bluetooth equipment which has quitted the network from the third queue.

And if the Bluetooth base station does not receive the broadcast message of the sixth Bluetooth device returning network in a third period, moving the unique mark of the sixth Bluetooth device to the end of the third queue.

The embodiment of the invention provides a Bluetooth networking method, which adopts a mode of active inquiry of a Bluetooth base station and passive response of Bluetooth equipment, and is different from a scheme that a request and a reply are required in four steps of connection establishment, connection request, connection establishment and connection disconnection in the traditional Bluetooth connection process. Can be at the in-process that bluetooth equipment went into the net, divide into groups and move back the net, the mutual flow between effectual reduction bluetooth basic station and the bluetooth equipment to carry out data transmission through the only sign that uses the bluetooth, the transmission capacity that can effectual reduction data reduces the complexity of the processing procedure of bluetooth equipment, improves bluetooth data transmission's real-time performance, through realizing that the quick income of bluetooth equipment nets and moves back the net, improves the reaction rate of bluetooth network deployment.

Specifically, after the bluetooth devices are grouped, the bluetooth devices which are connected to the network can be quitted, the bluetooth base station acquires the unique mark of the seventh bluetooth device which needs to be quitted through the internet, and the seventh bluetooth device is added into the fourth queue.

And selecting a preset number of Bluetooth devices from the fourth queue as eighth Bluetooth devices, generating a fourth broadcast message according to the eighth Bluetooth devices and the group quitting instruction, and sending the fourth broadcast message.
