Problems solved by technology

However, in the existing general distribution network function, the network distribution device can only configure undistributed network devices within its communication range, so its distribution network range is relatively narrow and the application scenarios are limited, which requires the design of Bluetooth mesh remote distribution network Function
First of all, in scenarios where the network coverage is large and the nodes are widely distributed, the remote distribution network based on the mainstream Bluetooth mesh takes a long time. Taking the Bluetooth mesh distribution network mechanism of Nordic Company as an example, because of the addition of auxiliary nodes, the network distribution steps Complicated, resulting in a longer network distribution time, affecting user experience
Secondly, the remote distribution network can only be opened manually and only one auxiliary node is allowed at a time, which reduces the flexibility and practicability of the distribution network

Embodiment 1

[0032] like figure 2 As shown, a Bluetooth mesh-based network distribution device starts a remote network distribution method, including the following steps:

[0033] S101, the network distributor sends remote network distribution and instructions:

[0034] The user sends out the command to open the remote distribution network by controlling the relevant buttons of the network distributor and becomes the key data that the ordinary node does not have to the selected neighbor node. The neighbor node is a node in the mesh network, so it can communicate with the network distributor, and then the neighbor node is The adjacent node of the Bluetooth device to be connected to the network, so the two can communicate directly. The key data includes the address range that can be allocated to avoid duplication problems during address allocation.

[0035] S102, the neighbor node starts the network distribution work after receiving:

[0036] After the key data of the network is allocate...

Embodiment 2

[0042] like image 3 As shown, a Bluetooth mesh-based network distribution device starts a remote network distribution method, including the following steps:

[0043] S201, the neighbor node sends a network allocation request after receiving the unallocated network beacon:

[0044]The Bluetooth device to be connected to the network broadcasts an unconfigured network beacon, seeking a network distributor to join the mesh network. The beacon includes information such as the device UUID and device capabilities. Neighbor nodes that are within the RF communication range of Bluetooth devices and support the remote network configuration function scan broadcast packets. When they scan the unconfigured network beacon sent by the device, they know that there is an unconfigured device nearby, so the neighbor node sends a remote activation to the network distributor. Configuration network request, requesting key configuration data to configure unconfigured devices to join the mesh networ...

Embodiment 3

[0054] like Figure 4 As shown, a Bluetooth mesh-based network distribution device starts a remote network distribution method, including the following steps:

[0055] S301, the bluetooth device receives a network configuration invitation from different nodes:

[0056] When there is more than one temporary network distributor in the mesh network, there will be the following situation. The location of the Bluetooth device that is not connected to the network is special, and many nearby neighbor nodes have enabled the remote network distribution function. At this time, there is a network distribution conflict or distribution network. Node selection problem, so it is necessary to design a distribution network node selection mechanism to ensure that the Bluetooth device selects a more suitable neighbor node to perform distribution network work.

[0057] S302, the Bluetooth device sends a request for remaining energy:

[0058] The step that consumes the most energy nodes is the e...

Abstract

The invention discloses a Bluetooth mesh-based optimized remote network distribution method and system. The system comprises a neighbor node role transformation module, an automatic awakening module and a node selection module, wherein the neighbor node role transformation module converts a certain neighbor node in the Bluetooth mesh network into a temporary network distributor according to an actual network distribution condition; the automatic awakening module actively initiates a network distribution request when the neighbor node in the Bluetooth mesh network receives the beacon which is not distributed with the network; and the node selection module selects a proper neighbor node to perform network distribution work in a Bluetooth mesh network node network distribution process, so that the conflict problem is effectively avoided. According to the invention, Bluetooth mesh remote network distribution work can be completed rapidly and effectively in a battery-powered scene with a large network coverage scale and wide node distribution, and the remote network distribution time is reduced.

Description

technical field [0001] The invention relates to the technical field of Bluetooth mesh remote network distribution, in particular to a Bluetooth mesh-based optimized remote network distribution method and system. Background technique [0002] The general provisioning function (Provisioning) in the Bluetooth mesh protocol specification refers to the process of adding Bluetooth devices to the mesh network by the provisioning device. The provisioning device can be a specific device or a smart phone, a smart tablet and other devices. The network configuration process is an extremely critical part of the Bluetooth mesh. Only when the device is successfully configured can it become a node in the mesh network. However, in the existing general distribution network function, the network distribution device can only configure undistributed network devices within its communication range, so its distribution network range is relatively narrow and the application scenarios are limited, wh...
