Method for connecting WI-FI network by intelligent hardware terminal based on sound waves and system for realizing same

Abstract

The invention provides a method for connecting a WI-FI network by an intelligent hardware terminal based on sound waves. The method comprises the following steps: intelligent equipment obtains an SSID (Service Set Identifier) and a password to be accessed into the WI-FI network of the intelligent hardware terminal, and converts the obtained SSID and password into a byte stream; the byte stream is converted into a sound wave signal according to an encoding rule and is transmitted by a loudspeaker; the intelligent hardware terminal receives the sound wave signal and converts the sound wave signal into a byte stream according to the encoding rule; then, the SSID and password to be accessed into the WI-FI network are analyzed, and obtained SSID and password information is connected with the WI-FI network. The method and the system can be effectively realized without additionally arranging other hardware modules on the intelligent hardware terminal, so that the method and the system have strong adaptability and are portable and easy to use.

Description

【Technical field】 [0001] The invention relates to short-distance wireless communication technology, in particular to a method for connecting a WI-FI network based on an intelligent hardware terminal based on sound waves, and a system for realizing the method. 【Background technique】 [0002] In recent years, wireless communication technology has been developed by leaps and bounds, especially the development of WI-FI (Wireless Fidelity, wireless high-fidelity) technology, which makes home and office networks more and more convenient. At present, most of the devices that support WI-FI obtain SSID (Service Set Identifier) ​​and passwords (such as smart phones, tablets, etc.) For various home appliances, printers, etc., the process of connecting to the WI-FI network is relatively complicated. [0003] At present, in order to access the WI-FI network, the intelligent hardware terminal of this type of UAV interaction interface has the following methods to obtain the SSID and passw...

AI Technical Summary

Problems solved by technology

This method is relatively cumbersome to operate, and requires an external computer, and the computer needs to install the corresponding device driver to connect to the smart hardware terminal.

If the smart hardware terminal is in the new WI-FI environment, it has to perform repeated cumbersome operations, and the applicability is too poor

[0004] The second method is to install a specific hardware module on the smart hardware terminal to be connected to the network, such as the SimpleLink WI-FI CC3000 module launched by Texas Instruments (TI), which allows the smart hardware terminal without a display to connect to WI-FI network, but this method increases the cost of the intelligent hardware terminal, and requires the intelligent hardware terminal to redesign the corresponding circuit, which increases the development cost of the intelligent hardware terminal

[0005] The third method is that if the intelligent hardware terminal is equipped with a camera, it can scan the two-dimensional code containing the network SSID and password information through the camera, and the intelligent hardware terminal can connect to the network after identifying the network SSID and password. access to the WI-FI network, this method is only applicable to smart hardware terminals with cameras, it is not applicable to general equipment, and the cost is too high

Once the smart terminal cannot connect to the WI-FI network for some reason, this method will fail

Therefore, this method is highly dependent on the network function of the smart terminal

[0009] 2. In the above method, the packet header sent by the smart terminal is the device identification, and only one device to be connected to the network can be connected to the WI-FI network at a time, which is inefficient and has great limitations

[0010] 3. In the above method, the message header and verification characters (header and tail) sent by the smart terminal are composed of several consecutive bits of 0 and 1, so it is likely to overlap with the SSID and password message, causing the verification to fail

Therefore, the above method is less feasible
