Embodiment 1

[0030] The application scenario of this embodiment is a set of intelligent lighting system. The intelligent lighting system adopts the self-distribution network networking method based on Bluetooth mesh without the main device for networking. It can be set that the smart light will automatically enter the network if it is powered on and not connected to the network. Networking mode, in the actual installation process, you only need to install all the lights, and then turn on the lights uniformly to make each light enter the networking mode.

[0031] Such as figure 2 As shown, the four lights are all slave devices, and there is no master device. The number of slave devices can also be other numbers, but there are at least two. Each device includes a memory, a processor, and a software program stored on the memory and operable on the processor. When the processor executes the computer program, the steps performed by each device in the following methods are realized.

Embodiment 2

[0042] Embodiment 1 is to establish an ad-hoc network distribution network for all devices without networking. Embodiment 2 is that a new device joins the ad hoc network in the case that there are already multiple devices in the ad hoc network.

[0043] For example, if there is a new smart light that needs to join the existing network, you can set the function of joining the networking button, or other manual trigger functions to make it enter the networking mode. As long as each device receives a signal to enter the networking mode, all devices re-enter the networking mode from step (1) of Embodiment 1 for a new round of self-configuration networking. Subsequent steps are the same as in Embodiment 1.

Embodiment 3

[0045] The third embodiment is that in the case of an ad hoc network with multiple devices currently existing, and some devices want to exit the ad hoc network, as in the second embodiment, each device can receive an entry into the group by pressing a button or other manual triggers. Network mode signal, all other devices except the device to be exited start from step (1) of Embodiment 1 to re-enter the networking mode for a new round of self-configuration networking. This method can remove and replace devices at will, which greatly reduces the hardware cost and maintenance cost of the networking.

Abstract

The invention discloses a Bluetooth mesh-based self-configuration network networking method and system without a master device. Multiple devices receive networking commands, enter the networking mode, and use the same key to self-configure the network; each device generates and broadcasts the network. Its own networking address, the networking address includes the MAC address of the device and a randomly generated element address; each device negotiates its own networking address, and stores the device list of all devices and the corresponding networking address; each device generates a new The key, the broadcast network address and the verification value of the new key; each device uses the new key to configure the network by comparing the new key verification value with the new key. The present invention can complete network distribution and networking under the condition of no main equipment, and also facilitates the control of equipment in the network. Using this method, the devices in the Bluetooth mesh network can be removed and replaced at will, which greatly reduces the hardware cost and maintenance cost of the networking.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a Bluetooth mesh-based self-distribution network networking method and system without a master device. Background technique [0002] With the characteristics of multi-hop interconnection and mesh topology, combined with the wide application of Bluetooth low energy, the wireless Mesh network can create a large network based on multiple devices. The network can contain dozens, hundreds or even thousands of Bluetooth Mesh devices , These devices can transmit information to each other, providing an ideal choice for various wireless access network solutions such as building automation, commercial lighting, sensor networks and smart homes. The cornerstone of creating a large network is the networking function of Bluetooth mesh. [0003] The networking function of the traditional Bluetooth mesh protocol requires an always-on master device, usually called a gateway. If a new ...
