Description
Technical Field
The utility model relates to a NFC communication technology, concretely relates to wiFi joins in marriage net system fast based on NFC.
Background
At present, with the development of science and technology, smart homes/household appliances are more and more popularized, and due to the wide application of home WiFi networks, at present, the smart homes/household appliances generally adopt WiFi to establish connection with a router so as to perform data interaction with a mobile phone/cloud.
For part of intelligent hardware, such as an intelligent socket, an intelligent air conditioner, an intelligent air purifier and the like, because the intelligent hardware does not have a human-computer interaction interface, the intelligent air conditioner can not search/select a designated router and input an interface for connecting a password like a computer, the problem of correct connection routing must be solved firstly.
The current WiFi configuration modes are generally 2 types:
1. the intelligent hardware is in an AP mode, the mobile phone is used in a station mode, the mobile phone is connected to the AP of the intelligent hardware to form a local area network, the mobile phone sends an SSID (service set identifier) and a password which need to be connected with a route to the intelligent hardware, and the intelligent hardware completes connection after actively connecting with the specified route.
A one-key configuration (smartconfig) mode, in which the intelligent hardware is in a promiscuous mode (can capture all 802.11 frames in the air) and monitors all messages in the network; the mobile phone APP encodes the SSID and the password into the UDP message, the UDP message is sent out through a broadcast packet or a multicast message, the intelligent hardware receives the UDP message and decodes the UDP message to obtain the correct SSID and the password, and then the intelligent hardware actively connects the route of the specified SSID to complete connection.
For the first configuration mode, a WiFi working mode of intelligent hardware needs to be configured, and the WiFi working mode of the mobile phone terminal is connected in a networking mode, so that the operation is complicated; although the second configuration method can achieve rapid configuration, the message including the SSID and the password is sent out in a broadcast packet or multicast packet mode through the mobile phone, so that the problem that the WiFi password is stolen easily exists, and the security is not high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the WiFi rapid distribution network system based on NFC is provided, and the problems of complex operation and low safety existing in the traditional WiFi distribution network scheme are solved.
The utility model provides a technical scheme that above-mentioned technical problem adopted is:
a WiFi rapid distribution network system based on NFC comprises equipment to be configured and a user terminal; the user terminal comprises an encoding module and a first NFC module; the device to be configured comprises a WiFi module, a decoding module and a second NFC module; the encoding module is used for encoding WiFi configuration information aiming at the equipment to be configured; the first NFC module is used for establishing communication with the second NFC module and sending the coded information to the second NFC module; and the second NFC module sends the received information to a decoding module for decoding, and the WiFi configuration information obtained by decoding is used for networking configuration of the WiFi module in the equipment to be configured.
As a further optimization, the user terminal is a mobile phone terminal.
The utility model has the advantages that:
the user only needs to use the mobile phone with the NFC function, and the WiFi configuration information (such as SSID and password) input on the app is close to the equipment to be configured, so that the configuration information can be quickly transmitted, the operation steps are simplified, and the security of the configuration information is improved compared with broadcast or multicast communication due to the adoption of the near field communication technology.

Detailed Description
The utility model aims at providing a wiFi joins in marriage net system fast based on NFC solves the problem that complex operation, security are not high that traditional wiFi joined in marriage net scheme existence. The NFC technology can provide short-distance wireless connection and achieve bidirectional interactive communication among electronic devices. NFC technology evolved from RFID (contactless radio frequency identification), but NFC has a specific set of standards that ensure interoperability of NFC-enabled devices. NFC adopts an electromagnetic coupling induction technology, the frequency of an electromagnetic field is 13.56MHz, and the carrier wave frequency band is a worldwide unlicensed wave band. The initiating device excites the antenna with a 13.56MHz signal, generating a magnetic field. And transferring energy to the target through near field coupling, modulating a magnetic field by the target, and returning data to the initiating equipment to finish communication. The utility model discloses it is exactly the short distance communication characteristics that have utilized NFC realize treating the quick net of joining in marriage of configuration equipment.
As shown in fig. 1, the system of the present invention includes a device to be configured and a user terminal; the user terminal comprises an encoding module and a first NFC module; the device to be configured comprises a WiFi module, a decoding module and a second NFC module; the encoding module is used for encoding WiFi configuration information aiming at the equipment to be configured; the first NFC module is used for establishing communication with the second NFC module and sending the coded information to the second NFC module; and the second NFC module sends the received information to a decoding module for decoding, and the WiFi configuration information obtained by decoding is used for networking configuration of the WiFi module in the equipment to be configured.
In specific implementation, an NFC chip may be added to a device to be configured, and the current mobile phone terminal has an NFC function and can be used as a user terminal. When the network is distributed, the mobile phone is close to the equipment to be configured, the APP software of the mobile phone is opened, the SSId and password of WiFi are directly input from the mobile phone, the input information is coded, the coded data are transmitted to the equipment to be configured through NFC near field communication, the equipment to be configured decodes and restores the data, and therefore the SSId and the password of the WiFi chip are obtained, and the network can be rapidly networked according to the information.
