Description
Technical field
The present invention relates to Internet of Things control technology fields, the more particularly, to method of realization hardware device networking.
Background technique
With Internet of Things, now with wifi network, smart phone it is universal, more and more household appliances start to walk intelligence
The road of energyization integrates wifi module in household appliance, by running the App installed on the intelligent terminals such as mobile phone to bind this
Wifi module, to achieve the purpose that household appliance is networked.The distribution of wifi module in present Internet of Things household appliance mainly uses
Smartlink and two kinds of SoftAp match net mode, i.e., are provided with Smartlink module or SoftAp module in home appliance.
Both modules are corresponding different with operation needed for net mode:
Smartlink matches net mode, i.e., passes through UDP (User Data by intelligent terminals such as mobile phone or PC
Protocol, User Datagram Protocol) send router SSID (Service Set Identifier, service set) and
The broadcast packet of password to household appliance wifi module, the wifi module of household appliance receive parse after broadcast packet SSID and
Password, then connection router is gone based on this, achieve the purpose that wifi module is networked.
SoftAp matches net mode, i.e. wifi module connects upper module hot spot initially as hot spot, the equipment such as mobile phone, carries out just
The SSID of router and password are transmitted to Wifi module by mobile phone A pp by normal network communication, and wifi module removes connection router,
Achieve the purpose that wifi module is networked.
Smartlink distribution only sends data in the form of multicast, and multicast distribution loses in this way in certain router
Packet rate is big.Be unable in some intelligent movable equipment forwarding multicasting (such as: iPhone6s) therefore limit the mutual of the prior art
The application and success rate of networking module networking technology.
Summary of the invention
The present invention is the above-mentioned shortcoming in order to overcome internet of things equipment networking technology in the prior art, provides one kind
Data packet can be sent according to special coding rule poll using broadcast and multicast, smart machine networking success rate can be improved
Based on multicast and broadcast combination send data packet realize hardware device networking method.
To achieve the above object, the invention adopts the following technical scheme:
A kind of method for realizing hardware device networking sending data packet based on multicast and broadcast combination of the invention, it is special
Sign is to the described method comprises the following steps:
Obtain the access authentication information of router；It will be described with net mode with net mode and SoftAp using Smartlink
Access authentication information sends data packet by broadcast and multicast poll and informs that household appliance, household appliance are based on the access authentication
Router described in information access.
Preferably, described match net mode for the access authentication information with net mode and SoftAp using Smartlink
The step of data packet informs household appliance is sent by broadcast and multicast poll, further comprise: each udp parlor is divided into 5ms,
Multicast and broadcast interval is sent.
Preferably, the sequence of giving out a contract for a project of each udp packet are as follows:
Interval sends multicast/broadcast lead code, and each inter-packet gap 5ms first sends out leading one group of multicast (3 packet), then sends out broadcast
One group leading (4 packet), total packet number, which is subject to, distributes complete leader code (6.8s)；
Interval sends all data of multicast and broadcast magic_code+data data portion, first sends out multicast one and takes turns, then sends out
One wheel of broadcast, every 1000 packet (are distributed and are completed subject to data) rest 1 second；
50s is a wheel, repeats above step.
Preferably, the multicast coding includes are as follows:
Multicast use address code, due to multicast address can only use 23bit, by the 23bit classify 2 regions:
The area metadata (7bit) and the area data (16bit) carry out data encoding；
The area metadata: only allow using low 7bit, high-order multicast address is fixed as 1；Metadata includes 2 parts, frame
Type+frame number；
The area data: 2 bytes can be transmitted in a frame, and low byte is in data0, and high byte is in data1.
Preferably, the multicast coding includes are as follows:
Lead code+magic code+sequence header+data, Intelligent hardware module identify data by lead code
Packet, and data packet (title and password of WiFi) is parsed by magic code and sequence header assembly, and with this
Company connects to the Net.
The embodiment of the present invention provides a kind of realization hardware device connection that data packet is sent based on multicast and broadcast combination simultaneously
The device of net, described device include:
Module is obtained, for obtaining the access authentication information of router；
Networking module is passed through the access authentication information with net mode with net mode and SoftAp using Smartlink
Broadcast and multicast poll send data packet and inform that household appliance, household appliance are based on routing described in the access authentication information access
Device.
It by multicast and broadcasts to router, poll sends data packet, and intelligent object is made to connect network.Wherein broadcast is volume
Code rule is hidden on data packet length to avoid the problem that router modification data packet causes.Each udp parlor is divided into 5ms,
Multicast and broadcast interval is sent.5ms is tested by most of router as a result, will lead to if frequency of giving out a contract for a project is too high
Router paralysis.
During Intelligent hardware market starts to be gradually warmed up, configuration smart machine this function of networking is particularly critical,
It directly determines that the people uses the enthusiasm of smart machine, is frequently found some Intelligent hardware products in the market existing and exists
Distribution success rate allows of no optimist in certain router.This programme just greatly improves the distribution compatibility issue of router.
