Rapid configuration system and method for wireless network

Abstract

The invention relates to a rapid configuration system and method for a wireless network. The system comprises a device already connected to the wireless network, and at least one device not connected to the wireless network and routers. An information encoding algorithm is adopted for encoding information into data packet sequences different in length, and the encoded data packet sequences are repeatedly transmitted to the routers inside the wireless network through a UDP at the interval of 100 ms; the wireless network card of the device not connected to the wireless network is set to be in a monitoring mode, and the device which is in the monitoring mode and is not connected to the wireless network captures all current data packets inside the wireless network, an SSID and a secrete key are obtained through analysis by the adoption of an information restoring algorithm, and therefore the device is smoothly connected to the routers inside the wireless network; the routers receive the data packets of the device already connected to the wireless network and do not need to process the received data packets. The configuration process is simple, configuration is rapid and reliable, configuration time is short, error correction and search algorithms are adopted, and therefore when the network environment is general (the packet loss rate is smaller than 70%), the success rate of configuration can be 100%.

Description

Technical field [0001] The invention relates to a wireless network configuration method, in particular to a fast and reliable wireless network configuration method, which is particularly suitable for the rapid configuration of wireless network by wireless equipment products such as security products and smart homes. Background technique [0002] At present, the configuration of the wireless device mainly needs to inform the device, the SSID and password of the router. At present, there are mainly the following methods: 1) Connect the device through the wire, then log in to the WEB interface, enter the SSID and password of the device, the main method of this method The disadvantage is that the device must support wired connection. 2) Configure the device's WIFI to hotspot (AP) mode, first connect to this hotspot with a mobile phone or computer. The main disadvantage of this method is that the computer or mobile phone must first connect to the device hotspot, then send the SSID and...

Problems solved by technology

[0002] At present, the configuration of wireless devices mainly needs to inform the device of the SSID and password of the router. At present, there are mainly the following methods: 1) First connect the device through a cable, then log in to the WEB interface, and enter the SSID and password of the device. The downside is that the device must support a wired connection

2) Configure the WIFI of the device as a hotspot (AP) mode, and use a mobile phone or computer to connect to this hotspot first. The main disadvantage of this method is that the computer or mobile phone must first connect to the hotspot of the device, and then send the SSID and password to the device, and then the device will go to the hotspot. Connecting to the router, the whole process takes a long time

3) By scanning the QR code with the camera, encode the SSID and password information of the router into the QR code through the mobile phone, and the device scans the QR code information encoded by the mobile phone through the camera to obtain the SSID and password of the router. The main disadvantage of this method is that the camera Before leaving the factory, it must be clearly focused, and the size and definition of the QR code pattern generated by different mobile phones are different due to different resolutions. It is difficult to find a suitable position when using it, resulting in a low recognition success rate.

The main disadvantage is that the device must support audio collection, and secondly, the decoding algorithm is relatively complicated, which leads to high CPU usage of embedded devices, which affects the normal use of other functions
