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, which belongs to the technical field of broadcast communication, and is characterized by comprising the following steps of: a, initiating a networking request data packet; b, returning a response and sending a data response packet; c, analyzing the data packet; d, waiting for the command target equipment to return a numbering success response packet; e, stopping numbering and commanding broadcasting, and performing second numbering after the first numbering is ended; and f, repeating the numbering process of the first terminal equipment by using the fifth target equipment as information source equipment, and sequentially propelling until numbering of all the terminal equipment is completed, thereby completing the ad hoc network. According to the invention, the spacing distance between the terminal devices is used as a reference point of communication delay, automatic networking is carried out according to the signal intensity of terminal device communication, the workload of manual input is reduced, the intelligent degree of terminal device networking is improved, and the method has the advantages of low communication protocol cost, stable performance, large networking capacity, good redundancy and the 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 ...
