Embodiment 1

[0030] see figure 1 , an ad hoc network method based on bluetooth broadcast communication, comprising the following steps:

[0031] a. Terminal device No. 1 first initiates a networking request packet as a source device;

[0032] b. Target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices return a response response and send a data response packet after receiving the networking request data packet;

[0033] c. Terminal device No. 1 performs data packet analysis after receiving the data response packets from target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices;

[0034] d. For the data packets of unnumbered devices, the No. 1 terminal device sets the numbering command packets sequentially according to the signal strength of the data packets, and sets the target device with the strongest signal as the No. 2, followed by No. 3, and so on, initiate a numbering command to ...

Embodiment 2

[0039] see figure 1 , an ad hoc network method based on bluetooth broadcast communication, comprising the following steps:

[0040] a. Terminal device No. 1 first initiates a networking request packet as a source device;

[0041]b. Target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices return a response response and send a data response packet after receiving the networking request data packet;

[0042] c. Terminal device No. 1 performs data packet analysis after receiving the data response packets from target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices;

[0043] d. For the data packets of unnumbered devices, the No. 1 terminal device sets the numbering command packets sequentially according to the signal strength of the data packets, and sets the target device with the strongest signal as the No. 2, followed by No. 3, and so on, initiate a numbering command to N...

Embodiment 3

[0049] see figure 1 , an ad hoc network method based on bluetooth broadcast communication, comprising the following steps:

[0050] a. Terminal device No. 1 first initiates a networking request packet as a source device;

[0051] b. Target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices return a response response and send a data response packet after receiving the networking request data packet;

[0052] c. Terminal device No. 1 performs data packet analysis after receiving the data response packets from target device No. 2, target device No. 3, target device No. 4, target device No. 5 and other terminal devices;

[0053] d. For the data packets of unnumbered devices, the No. 1 terminal device sets the numbering command packets sequentially according to the signal strength of the data packets, and sets the target device with the strongest signal as the No. 2, followed by No. 3, and so on, initiate a numbering command to ...

Abstract

The invention discloses an ad hoc network method based on bluetooth broadcast communication, belonging to the technical field of broadcast communication. c. Data packet analysis; d. Wait for the command target device to return a numbered successful response packet; e. Stop the numbering and command the broadcast, the first numbering ends, and the second numbering is performed; f. The target device No. 5 is used as the source device to repeat 1 The numbering process of terminal equipment is advanced in sequence until the numbering of all terminal equipment is completed, and the ad hoc network is completed. The invention takes the interval distance between terminal devices as the reference point of communication delay, and automatically forms a network through the signal strength of the communication of the terminal devices, reduces the workload of manual input, improves the intelligence of the terminal device network, and has the advantages of The communication protocol has the characteristics of low cost, stable performance, large networking capacity, good redundancy and stable network.

Description

technical field [0001] The invention relates to the technical field of broadcast communication, in particular to an ad hoc network method based on bluetooth broadcast communication. Background technique [0002] The existing system composed of Internet of Things devices that network devices in the form of columns usually uses QR code scanning, RFID scanning, or manual input of device numbers to define whether the devices belong to terminals, relays, and gateways. , and then perform data communication according to the configuration information. Although this traditional method is effective and reliable, when a large number of devices are installed, there are problems such as slow input of devices and increased labor costs. [0003] The Chinese patent document with the publication number CN 111328037A and the publication date of June 23, 2020 discloses a highway tunnel communication system based on Bluetooth MESH technology. A router, at least two MESH configuration servers ...
