Embodiment 1

[0042] Acoustic distribution network means that the master device uses the sound of a specific frequency as the information carrier, and synchronizes the network configuration information such as the SSID and password of the router obtained by it to the slave device. Using sound waves as a transmission carrier to carry network configuration information refers to converting network configuration information into sound wave sequences using sound wave coding algorithms.

[0043] In this process, sound wave transmission technology is particularly important. The sound wave transmission technology is simply to map the characters to be recognized into frequencies at the sending end, and then map a frequency into a syllable signal (single frequency sine wave) and encode it into audio playback; after receiving the audio signal at the receiving end, Analyze the frequency, and then find the character corresponding to the frequency according to the common code table on both sides, so as t...

Embodiment 2

[0067] This embodiment provides an acoustic wave network distribution device, such as Figure 6 As shown, the device includes:

[0068] The distribution network information sending module 1 is used for the sending end to convert the network configuration information into a JSON string, encode the JSON string by means of variable length encoding, and perform frequency mapping on the code stream formed by the encoding to obtain the corresponding sound wave sequence , sent to the receiver;

[0069] The distribution network information receiving module 2 is used for receiving the sound wave sequence at the receiving end, performing time-frequency analysis on the sound wave sequence to obtain a time sequence of frequency change, and performing variable-length decoding on the time sequence to obtain corresponding network configuration information.

[0070] The specific content and implementation methods of the distribution network information sending module 1 and the distribution n...

[0073] Please see Figure 7 , the acoustic wave distribution network equipment 500 may have relatively large differences due to different configurations or performances, and may include one or more processors (central processing units, CPU) 510 (for example, one or more processors) and memory 520, One or more storage media 530 (such as one or more mass storage devices) storing application programs 533 or data 532 . Wherein, the memory 520 and the storage medium 530 may be temporary storage or persistent storage. The program stored in the storage medium 530 may include one or more modules (not shown in the figure), and each module may inc...

Abstract

The invention discloses a sound wave network distribution method, device and equipment and a storage medium, and the method comprises the steps that a transmitting end converts network configuration information into a JSON character string, carries out the coding of the JSON character string in a variable-length coding mode, and carries out the multistage frequency hopping coding of a code streamformed through coding, thereby achieving the frequency mapping, and obtaining a corresponding sound wave sequence; the sound wave sequence is sent to a receiving end; and the receiving end receives the sound wave sequence, performs time-frequency analysis on the sound wave sequence to obtain a time sequence of frequency change, and performs variable-length decoding on the time sequence to obtain corresponding network configuration information. By adopting the sound wave network distribution method, the network distribution efficiency can be effectively improved, and the network distribution failure rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of network configuration, and in particular relates to an acoustic wave network distribution method, device, equipment and storage medium. Background technique [0002] With the development of the mobile Internet and the Internet of Things, various smart home devices are emerging rapidly, which need to be connected to the Internet for remote control. Its way of connecting to the network has developed from the initial physical connection method of using a wired connection to a computer or mobile phone, and then performing network configuration, to a wireless connection method that does not require peripherals such as a screen or keyboard and directly configures the network through WiFi. [0003] However, the existing commonly used network distribution methods such as Bluetooth or WiFi need to be implemented with the help of corresponding peripheral hardware, and the overall cost of the equipment is relatively...
