Embodiment Construction

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Bluetooth low energy (BLE) technology is a feature starting from the Bluetooth V4.0 version, which is a low cost, short distance, interoperable robust wireless technology, working in a 2.4GHzISM RF band. It is designed as ultra-low power (ULP) wireless technology from the beginning, which maximizes power consumption in many intelligence. The transmission range of BLE4.0 can generally reach 50 to 100 meters. BLE5.0 can reach 800 meters.

[0033] Traditional Bluetooth uses 16 to 32 frequency bands, while BLE uses only 3 broadcast bands; the radio frequency opening time of each broadcast is reduced by 0.6 to 1.2 ms of the traditional Bluetooth 22 ms.

[0034] Bluetooth BLE interactions There are two roles: Central Roles (Central) and peripheral, which can compare the traditional CS structure, is understood as the client-server structure.

[0035] Center Role: Y...

Abstract

The invention discloses an intelligent door lock Bluetooth node role switching and networking method based on the Internet of Things. The intelligent door lock Bluetooth node role switching and networking method comprises the following steps: step S1, role switching process; each Bluetooth node is circularly switched between a peripheral role and a central role; the Bluetooth node with the peripheral role broadcasts and sends routing table information; the Bluetooth node with a central role scans and receives routing table information; and each Bluetooth node collects routing table information from other nearby nodes and establishes a routing table of the Bluetooth node until all the nodes join and form a mesh network. According to the scheme, the intelligent door lock with the Bluetooth module is used as the Bluetooth node, the routing table information is exchanged in a broadcasting and scanning mode through role switching, and the routing table of the intelligent door lock is established, so that each node can obtain the networking information of the Bluetooth node in the whole system, and an amorphous network adapting to the environment is formed.

Description

Technical field [0001] The present invention belongs to the technical field of wireless communication networking, and in particular, the IoT-based smart door lock Bluetooth node role switching and networking method. Background technique [0002] With the rise of the Internet of Things industry, smart home appliances have gradually entered people's lives, how to establish intelligent equipment network connectivity has become the current technical point of the current hot. Currently, the intelligent terminal is connected to a smart home node through a dedicated control node, and then forward the intelligent terminal instruction to other smart home nodes by the control node. [0003] The smart door lock, one of the important equipment of the Internet of Things is an important part of the rental housing intelligent management solution. For example, the rooms in the entire building are all rented for rental housing and configured a smart door lock with Bluetooth modules for each house...
