Problems solved by technology

[0006] Method 1: Some smart terminals are not compatible with multicast. In this case, smart terminals cannot send multicast data normally. In this way, this method has certain limitations; UDP data packets sent in the form of multicast are formed The data carried in the destination MAC field of the 802.11 data frame is limited, the first 25 bits of the MAC address are forcibly defined as 01005e, and the last 23 bits that can carry data correspond to the last 23 bits of the multicast IP address
The 802.11 data frames formed by UDP broadcast packets carry less data and need to send more data packets, which are easily interfered

[0060]In the first embodiment of the present invention, a network access method for home appliances, such as figure 1 As shown, the process executed on the home appliance side includes the following specific steps:

[0061] Step S101, in the sniffer monitoring mode, receiving the probe request ProbeRequest frame sent by the smart terminal;

[0062] Specifically, step S101 includes:

[0063] In the sniffer monitoring mode, receive the ProbeRequest frames sent by the intelligent terminal from each wireless working channel in turn; once the ProbeRequest frame is received, it is judged whether the first selected information in the selected field of the received ProbeRequest frame is Satisfy the set conditions.

[0064] Step S102, judging whether the first selected information in the selected field of the received ProbeRequest frame meets the set condition, and when the set condition is met, obtain the wireless route from the second selected information in the selected field inf...

[0071] The second embodiment of the present invention is a network access method for household electrical appliances, which is also a process performed on the household electrical appliance side. The method described in this embodiment is roughly the same as that in the first embodiment. In step S102, wireless routing information is obtained from the second selected information in the selected field, specifically including:

[0072] A1: read the wireless routing information from the second selected information in the selected field;

[0073] A2: Decrypt the read wireless routing information.

[0074] Preferably, obtaining the wireless routing information from the second selected information in the selected field also includes:

[0075] The format of the decrypted wireless routing information is verified, and the verified wireless routing information is used as the finally obtained wireless routing information. Wireless routing information includes: SSID and password. The for...

[0078] In the third embodiment of the present invention, a network access method for home appliances, the process executed on the smart terminal side includes the following specific steps:

[0079] A probe request ProbeRequest frame is sent, the first selected information in the selected field of the ProbeRequest frame satisfies the set condition, and the second selected information includes wireless routing information for the home appliance to access the wireless router.

[0080] Specifically, the smart terminal starts active scanning at the application layer, and sends a ProbeRequest frame on each wireless working channel or on any wireless working channel through the wifi driver layer.

[0081] The selected fields include: element identification 221 field;

[0082] The first selected information includes: OUI, and the second selected information includes: data.

[0083] In the fourth embodiment of the present invention, corresponding to the first embodiment, a network acc...

Abstract

The invention provides a network access method, device and related equipment for household appliances. At the household appliance side, the method comprises the steps of: receiving a probe request frame from an intelligent terminal under the sniffer monitoring mode; determining whether the first selected information in the selected field of the received probe request frame satisfies the set condition, and obtaining the wireless router information from the second selected information of the selected field if so; and accessing a wireless router based on the wireless router information. By the invention, household appliances under the sniffer monitoring mode can rapidly and safely obtain the wireless router information so as to access the network. The network access method, device and related equipment of the invention achieve wide implementation applicability, and support multicast without the need of an intelligent terminal and a router. In addition, configuration can be completed by single interaction, and the total number of data packets is smaller than that of the prior art, thereby saving the network overhead and shortening the configuration time.

Description

technical field [0001] The invention relates to the technical field of network access of smart home appliances, in particular to a network access method, device and related equipment of home appliances. Background technique [0002] At present, home appliances are generally connected to the Internet through wifi, and are interconnected with devices such as mobile phones and other smart terminals through the Internet. The typical configuration methods adopted by the wifi module of the existing household appliances are as follows: [0003] Method 1: The home appliance starts the sniffer monitoring mode, the smart terminal connects to the router, and sends a UDP (UserDataProtocol, User Datagram Protocol) data packet in the form of multicast, and the destination MAC (MediaAccessControl, media access control) in the UDP data packet The control) address is a MAC address including a specific code obtained by the mobile terminal according to IP (Internet Protocol, Internet Protocol...
