Those skilled in the art should know IP address space is divided into A, B, C three classes.Four classes, that is, D class address quilt Reservation is used as multicast address.In the IP agreement (IPv4) of fourth edition, from 224.0.0.0 to 239.255.255.255 between institute There is IP address to belong to D class address.

Most importantly the 24th this four to 27 interdigits in multicast address, corresponding to the decimal system is 224 to 239, Its 28 reservation is used as the group mark of multicast, as shown in Figure 1.

The multicast address of IPv4 will be converted into network physical address in network layer.To the network address of a unicast, pass through The available physical address corresponding with IP address of ARP protocol.But ARP protocol is unable to complete similar functions under multicast mode, It must handy other methods acquisition physical address.It is proposed in the RFC document being listed below and completes this conversion process Method:

RFC1112:Multicast IPv4 to Ethernet physical address correspondence

RFC1390:Correspondence to FDDI

RFC1469:Correspondence to Token-Ring networks

Within the scope of maximum ethernet address, conversion process is such that most fixed by first 24 of ethernet address For 01:00:5E, this several are important flag bit.Back to back one is fixed as 0, and other 23 in IPv4 multicast address Low 23 fill.The conversion process is as shown in Figure 2.For example, multicast address is that 224.0.0.5 its Ethernet hardware address is 01:00:5E:00:00:05.As can be seen that 23 low (can also be less) of object here address field can be used as editable Bit area, for load information.

In addition, frame ontology domain, i.e. Frame Body, the length of this partial content is variable, and the content specifically stored is by frame Type (type) and subtype (sub type) determine.

As can be seen that the destination address domain and frame ontology domain in multicast packet frame are two editable field, transmitting terminal can Editable bit area i.e. its low 23 content and the length in control frame ontology domain in destination address domain is arranged.

When smart machine is not connected with WiFi access point, WiFi chip is the radiofrequency signal that can be detected in space And identify mac frame, but equipment can not further parse frame knot because the certification by access point does not have key at this time The data in frame ontology domain in structure, but due to the frame length in frame ontology domain it is found that the frame length to entire multicast packet frame can also Know, therefore, this characteristic has no effect on the utilization of the frame length to multicast packet frame.So the present invention is by utilizing these words Section, so that the letter that control of intelligent terminal is sent with multicast mode can be received smart machine is not in the case where networking Breath.In fact, will also realize that according to the specification of 802.11 agreements, for a multicast packet frame, the length of entire frame is only It is associated with and is decided by one property the length in frame ontology therein domain.

It can be seen that for multicast packet frame according to the knowledge of the disclosure above, the destination address domain in frame structure And its variation of frame body length is used equally for load configuration information.The knowledge of the disclosure above is the base for understanding realization of the invention Hereinafter the announcement to method of the invention will be unfolded based on above-mentioned knowledge in plinth.

A kind of smart machine networking control method provided by the invention, typically as active initiator, or as in It entreats the visual angle of controlling party to be described, this method can be embodied as by computer program by programming and be mounted on similar hand Machine, tablet computer or have intelligentized control of intelligent terminal in run, for example, operation Android, IOS, Windows The mobile phone of Phone system or the APP (application program) that transmission method realization is utilized with installation in tablet computer, apply journey by this Sequence executes the transmission method.

Referring to Fig. 3, in an exemplary embodiments of smart machine networking control method of the invention, it should be noted that It is that this method is realized in control of intelligent terminal, and this method specifically comprises the following steps:

Step S11, display user interface is used to obtain the configuration information for making the smart machine access target network.

It, can be by system drive on mobile phone when the APP is run by taking the APP realized based on the present invention as an example Hardware device utilized.It is well known that not only having WiFi mould group, display, control chip on mobile phone, also there is wheat The components such as gram wind, loudspeaker, these components, which can pass through the APP, to be realized and calls.

By taking android system as an example, mobile phone calls first and shows a movable component (Activity), or display one A page realized using HTML5, shows the user interface on the screen and the WiFi access-in point information that scans is (with services set Mark SSID is enumerated), user's selected target network is requested, and user is required to input corresponding password, to obtain target network SSID and password.

According to the agreement of WiFi agreement, those skilled in the art be could be aware that, configuration information generally includes WiFi without route By the service set (SSID) and login password of (representing target network), may also need to include that login is close in some cases The cipher mode of code, and login password can also be needed not be provided for open network.Although there are the things of version upgrading for WiFi agreement It is real, but these are related to and realize access network and the configuration information of indispensability can be corresponding according to document of agreement by those skilled in the art It determines, therefore, its details and its equivalent variations scheme is repeated here.

As details accommodation, after user has selected SSID, can be inquired to cloud server corresponding to the SSID Password can save the step of requiring user to input target network password if password exists.

Step S12, the configuration information is encoded in multiple multicast packet frames two possessed by each multicast packet frame A editable field.

It after obtaining the configuration information, needs to encode the configuration information, forms frame data.For this purpose, please join Fig. 4 is read, realizes cataloged procedure according to following specific steps:

Step S121, the corresponding coded sequence of the configuration information is separated into multiple sequences, define each sequence with for The respective index string of its characterization indexed sequential distributed is coding unit.

The configuration information, as previously mentioned, can be in an application scenarios comprising for providing WiFi access point Service set (SSID) and its password information.Configuration information can be first by format before being replaced into corresponding coded sequence Turn to character string information.Specifically, service set and the equal configuration information element of password, separated between information element with element Symbol " | " is separated, and is separated between the mark and value of information element with attribute separator ": ".Such as service set be with SSID indicates its mark, and password indicates that its mark, the value of SSID are MYWiFi with PSW, and the value of password is PLZLOGIN, to its into The information content that formatting lines are formed are as follows:

The coded sequence is converted into binary system acquisition based on the above-mentioned format string of configuration information.In order to Keep configuration information safer, first configuration information (above-mentioned character string) can be encrypted, forms ciphertext and be reconverted into later The coded sequence.The mode of encryption is either public key encryption, is also possible to symmetric key encryption, as long as receiving end utilizes Corresponding key (the same key in private key or symmetric cryptography in such as public key encryption) can decrypt.Either encrypt Or disclosed state, after configuration information is resolved to binary code, it can be encoded, be adapted to be assigned to each In multicast packet frame.

Firstly, the coded sequence of configuration information is separated into several sequences, each sequence constitute it is relatively independent and without letter The a part for ceasing meaning, is expressed, such as occupy 20 bits with same length.Then, one is distributed for each sequence Index string, this sequence similarly also use binary expression, occupy such as 6 bits, under the format of 6 bits, can be used for table Up to 2⁶Group sequence.It then, can according to the numerical values recited of index string for each sequence group unification index string It is expressed with the proper sequence to the sequence, i.e., the sequence that coded sequence is isolated is matched accordingly by its serial connection sequence The index string of size makes the index string can be used for expressing the indexed sequential of sequence corresponding thereto.It completes therefrom The partition and sequence of entire coded sequence.Wherein, it is the convenience illustrated, each index string and sequence in combination is defined as One coding unit, then configuration information is just separated into multiple coding units, and each coding unit is relatively independent, but between each other It is ordered into.It should be noted that coding unit itself is a combined concept, rather than the concept that a sequence is fixed.In order to Realize the utilization to multicast packet frame, the total length of coding unit is determining totally 26 bit, and the index string occupies therein First length totally 6 bits, and remaining second length, 20 bit is then the total length of coding unit occupied by corresponding sequence Exactly the sum of the first length and the second length.Obviously, all coding units total length all having the same.

The configuration information is separated into after multiple coding units, can carry out next code based on multicast packet frame.

Step S122, based on multicast packet frame format construct reference frame, initialize two editable field of the reference frame with Determine benchmark.

The construction of the reference frame is more flexible, can be on the basis of multicast packet frame, according to aforementioned related multicast number According to the announcement of the structure of frame, by the editable bit area in its destination address domain, i.e., its low 23 bit is all set to 0 or 1, Or other specific bit sequences can also, and determine its frame ontology length be benchmark length.On this basis, as long as Reference frame recipient can abide by specification of the invention, can according to identifying the reference frame to the coding principle of reference frame herein, And the length is determined as fundamental length by the length that can determine the frame ontology domain.As equivalent replacement means, due to frame sheet The length in body domain determines the length of entire reference frame, therefore, can also be directly using the total length of reference frame as benchmark length.The base Standard length is less than the frame length of follow-up frame, to determine information coding by the difference between this frame length.Similarly, As equivalent replacement means, the frame length of reference frame can also be made to be greater than the frame length of follow-up frame.

Step S123, it is based on multicast packet frame format tectonic information frame, each coding unit is divided into two parts content point It is not expressed in two editable field of a corresponding information frame.

Due to the present invention relates to the utilization to information frame and the frame length difference of reference frame, it can the specification difference The variation range of value keeps the variation range specific, and frame length difference between information frame and reference frame is made to maintain a specific model It is temporarily embodiment with maximum value 8 within enclosing.In a computer, it can indicate that various differences are poor with 3 Binary Zero 00-111 Value, when its low 23 combination with foregoing purpose address field, just can constitute 26 abilities to express, wherein 6 position index string energy 64 groups of data are expressed, remaining 20 in every frame can then express the data volume of 2.5Bytes, and first encoding can meet The expressive faculty of 160Bytes information content.

Similarly, the information frame is also to be constructed based on multicast packet frame.The mistake of the construction information frame Journey is that each coding unit is respectively corresponded to the process for being encoded to an information frame.Each coding unit outlined below and letter Cease the several ways of encoding relation between frame structure.

The first coding mode:

Sequence included by coding unit is divided into two parts, i.e. the first subcode string and the second subcode string, if the first son Sequence is 17, and the second subcode string just occupies complete 3 of the difference.And concatenation should before the first subcode string of each sequence Index string in coding unit, therefore, index string and the spliceosome of the first subcode string are just 23 bytes, are just equal to group 23 editable bit areas that multicast data frame provides, expression is wherein.And the second subcode string, it is assumed that be 010, represent the decimal system Numerical value 2 then can be such that the frame length of information frame is greater than (in other embodiments by the length in the frame ontology domain of determining information frame Be also possible to be less than) frame length (datum length) 2Bytes of reference frame and realize coding expression.Follow-up recipients utilize information After the frame length of frame subtracts the account length of reference frame, 010 this second subcode string can be obtained.

Second of coding mode:

This coding mode the difference is that only that the object being split is in coding unit with former coding mode Index is gone here and there rather than its sequence, due to that sequence overall length 20, it can be expressed in completely in the data of the example of above-mentioned offer In the editable bit area of multicast packet frame, therefore, editable bit area can only be for 3 in expression index string in this case Position, i.e. the first subindex string, and residue 3 i.e. the second subindex strings for indexing string can only the first referenced aforementioned coding mode It is expressed in the frame length difference of the information frame described in it and the reference frame.

In the example of aforementioned two ways, 6 position index strings low with destination address domain with the length of 20 sequences 23 and frame This Matching Relation between length difference 3 is preferred scheme, can either reinforce multicast packet frame expression letter as much as possible The ability of breath, but caused by can reduce because of UDP message packet packet loss in transmission process information unsuccessful transmission risk.

The third coding mode:

Sequence in coding unit is simply directly expressed in the destination address domain of its affiliated information frame by this coding mode In, such as low 20 of destination address domain are occupied, and index string is expressed in the frame of its affiliated information frame and the reference frame In length difference.If indexing 6 that the length gone here and there is maintained precedent, the difference range of the frame length of information frame and reference frame The range for the maximum value that corresponding 6 binary codes can express should be maintained.If reducing the digit of index string to 3, even if The entire editable area that lengthened code string length makes it occupy destination address domain to 23 can only express 8 groups of numbers due to index string According to, therefore its information representation ability is also to be weaker than precedent.

4th kind of coding mode:

Similarly with the third coding mode, the index string in coding unit simply can be expressed in its affiliated information frame In destination address domain, such as low 23 of destination address domain are occupied, and information frame belonging to sequence is all expressed in and described In the frame length angle value of reference frame, if the length of sequence is maintained 20 of precedent, the similarly frame length of information frame and reference frame The difference range of degree should be maintained the range for the maximum value that corresponding 20 binary codes can express.If reducing the digit of sequence To described 3 as in the previous example, then the information content of single sequence expression is relatively limited, and indexing string is 23, thus needs structure Multiple multicast packet frames are made to transmit the same information, it can be seen that, aforementioned first and second kinds of coding modes better than third and 4th kind of coding mode.

By the announcement of above four kinds of coding modes, could be aware that, anyway, it is ultimately constructed made of information frame, Editable bit area in one of two editable field, i.e. destination address domain, in particular to the domain will include volume described in one First part's content of code unit, this partial content can be the whole or part of it subcode string of sequence, be also possible to index The whole or part of it subindex string of string.And the frame length of the information frame, by its another editable field, that is, frame ontology domain The adjustment of length, making its frame length with the reference frame, there are the difference in a particular range, the binary systems of this difference Format just contains the remainder content not being encoded into the destination address domain in the coding unit, this partial content Type and number type and number expressed by the destination address domain depending on, either the subcode of the remainder of sequence String, is also possible to whole sequences, can be the whole or its remainder index string of index string.In short, same coding unit institute The sequence and index string that include can depend on actual need and are discretely expressed in the destination address domain editable of same information frame Among the frame length difference of bit area and the information frame and the reference frame, the construction of the information frame is completed.

After completing aforementioned each specific steps, that is, the entire cataloged procedure of the configuration information is realized, phase is obtained The reference frame and information frame answered.

Step S13, the multicast packet frame described in wireless transmission, to start the networked deployment to smart machine.

The construction of the reference frame and information frame is completed, whole coding works of the configuration information are just completed, by This, calls the corresponding interface, using the WiFi communication component based on 802.11 agreements, can by the reference frame and information frame with Wirelessly to aerial radiation, it is transferred to receiving end.It should be pointed out that since upper-layer protocol is worked with UDP, institute With, the reference frame and information frame are sent with UDP message packet, since udp protocol is unreliable protocol, thus, this method When transmitting the reference frame and information frame, set such as 10 times circulations, in each circulation, by the reference frame and information frame according to (reference frame, which is considered as, is encoded to 0 sequence the first) is successively sent according to the indexed sequential of index string list sign, to ensure that receiving end is smooth Receive whole multicast packet frames.Nevertheless, reference frame and information frame are also possible to random ordering in the transmission sequence of same one cycle , have no effect on implementation result of the invention.It should be noted that the number cycled through when transmission also should not be limited to certain number Word can be more wheels transmission of such as 5 times, 20 other inferior data.

After the reference frame and information frame are received by smart machine, smart machine will start its connection according to blas Net configuration, utilizes transmitted configuration information to configure behind, the target network is accessed, to realize networking.Related intelligence Energy equipment realizes the process of networking, refering to subsequent announcement.

As can be seen that control of intelligent terminal only has issued reference frame and information frame in this step, in case starting is to intelligence The networked deployment of equipment operates, not configuration of the actual implementation to the network settings of Intelligent hardware, but certainly by smart machine Body, using control of intelligent terminal transmission come networked deployment information go to realize, in this regard, those skilled in the art should be known photograph.

Step S14, the control operation interface for interacting with the smart machine is provided for the smart machine after networking.

As previously mentioned, when control of intelligent terminal the configuration information is sent to smart machine and start its networked deployment it Afterwards, smart machine will complete the network insertion process of itself, also, when necessary, the information that smart machine can network success Feed back to control of intelligent terminal.

It should be pointed out that since this method is not necessarily dependent on control of intelligent terminal with smart machine based on similar AD- The interconnection that the technology of HOC or WiFi Direct etc is realized in advance, only need to be to aerial wireless communication of the radiation containing multicast packet frame Number, thus, control of intelligent terminal can keep the company with the target network during the entire process of this method executes It connects without carrying out that complicated switching need not disconnect the connection with target network and smart machine described in accessing and is transmitting Switchback accesses the target network after configuration information, thus, control of intelligent terminal can be in the company for keeping accessing the target network While connecing state, the multicast packet frame is sent, without influencing its normal cluster.And smart machine accesses same WiFi and connects After access point, udp broadcast can be sent by the corresponding WiFi AP and control of intelligent terminal realizes local area network communication, thus The information for itself being successfully accessed target network can be fed back to control of intelligent terminal by local area network.

In fact, in addition to this it is possible to having other way that control of intelligent terminal is allowed to know that smart machine successfully joins Net, for example, after the APP of control of intelligent terminal and smart machine pass through cloud server and the binding of same user account, into One step uploads data to cloud server, and is recorded by cloud server, which can be by corresponding on control of intelligent terminal Application program identified, control of intelligent terminal accordingly be knowable smart machine completed to access.

Correspondingly, control of intelligent terminal can pass through the datagram of such as HTTPS using cloud server as intermediary Text submits the request for acting on smart machine to cloud server, and the interaction of data and instruction is realized with smart machine.No matter what Kind mode be communicated when control of intelligent terminal can be realized with smart machine, can be provided by its APP for setting with the intelligence The standby control operation interface interacted carries out control operation to user.

The control operation interface that control of intelligent terminal provides can be realized using two ways.First way is to be based on The Webpage exploitation of HTML5 etc, after knowing that smart machine has accessed internet by mobile phone terminal, to cloud service Device pulls the corresponding page, and user is showed to execute relevant operation.The second way be realized based on local program, such as An Activity is constructed in the application program of Android, is obtained by the Activity and is shown the related intelligence of cloud server Can equipment related data or directly interacted from local area network with smart machine, and show the control operation interface.

The control operation interface that user is provided by the corresponding application program of control of intelligent terminal, can initiate to intelligence The operation of energy equipment, including controlling functional mapping of smart machine, the data for showing smart machine offer etc..Thus meet user Concentration, permit ease of administration to Intelligent hardware.

As can be seen that the smart machine networking control method completed according to aforementioned process, cataloged procedure is simple, information table Danone power is strong, needs not rely upon foundation between control of intelligent terminal and smart machine and is stably connected with and can realize having for configuration information Control smart machine networking is realized in effect transmission at faster speed.

It is corresponding, in the other end corresponding with aforementioned intelligent controlling terminal, usually controlled smart machine, such as intelligently Camera, automobile data recorder, smartwatch etc., this kind of equipment, which is generally required, completes itself dependent on configuration information above-mentioned Configuration is to access external network.In order to receive configuration information above-mentioned, just need that such equipment is made to have decoding afore-mentioned code The multicast packet frame that procedure construction goes out reaches the basis of the operation of next step.

For this purpose, referring to Fig. 5, the present invention is further that smart machine side discloses a kind of networking cut-in method, this method Include the following steps:

Step S21, the multicast packet frame for being loaded with the configuration information for accessing target network is received.

Smart machine is received by it by the WiFi communication mould group of 802.11 specifications described in the air with wireless signal transmission UDP message packet obtains corresponding multicast packet frame, is then decoded to it, loads finally to obtain in multicast packet frame Configuration information.

Since reference frame and information frame are realized with certain coding principle, when decoding, naturally also will in accordance with Corresponding principle when coding, therefore for, decoding side of the invention and coding staff are both needed to same in accordance with being standardized by the present invention Set makes agreement by oneself.In view of this, this method is referring to method above-mentioned, referring to Fig. 6, being obtained according to following specific steps described Reference frame and information frame:

Step S211, receiving multicast data frame:

The UDP message packet that on-air radio radiation is obtained by WiFi communication mould group, can obtain multicast packet frame therein, So that the type to multicast packet frame identifies.

Step S212, judge there will be specific content whether comprising specific content in the editable field of the multicast packet frame Multicast packet frame be determined as reference frame:

The specific content refers to and makes agreement by oneself according to what this method was abided by, checks the mesh of the multicast packet frame Address field editable bit area in, if contain the content for meeting the agreement and being standardized.Such as defined in former approach 23 bits be full 0 or complete 1, if meeting such case, that is, be considered as that there are specific contents.It can also further check the group The frame length of multicast data frame, since the frame length of multicast packet frame is uniquely decided by the length in its frame ontology domain, so It can check the length in its frame ontology domain, if meet data as defined in agreement, if one of these conditions or all satisfaction are certainly Determine the specification of agreement, then the multicast packet frame is just judged as reference frame, otherwise, then can temporary packet loss.

Step S213, other multicast packet frames for not including specific content are determined as information frame:

When previous sub-step determines the multicast packet frame for reference frame, currently received serial multicast packet frame is characterized Rest part contains information frame, can start to receive remaining multicast packet frame as a result, that is to say the information frame.By It is that more wheels send the reference frame and information frame in sender's (control of intelligent terminal), thus, in this sub-step, work as determination After reference frame, remaining multicast packet frame can be received all, and it is duplicate can be handled with packet loss, it is final obtain reference frame and its Unduplicated information frame.Theoretically, it is discussed with aforementioned one embodiment, since index string has 6, reference frame and information frame Summation should be 64, depending on the digit that specific view index is gone here and there.It, can be by described according to index string as further test condition Whether expressed data group number and its characterization sequence, have received that all unduplicated information frames and reference frame to verify, Remaining person all packet losses are handled.Further, the difference of the frame length of the frame length and reference frame of checking information frame can also be passed through Whether value exceeds the particular range of a pre- agreement, and determines whether the information frame is to be loaded with defined by the present invention with confidence Thus the information frame of breath implements a substantial frame check process in this sub-step.In addition, corresponding to what former approach provided Several variation instances, since the frame length of information frame is obviously more than or less than the frame length of the reference frame (by making agreement institute by oneself Specification), i.e. the frame length of reference frame is less than or greater than the frame length of the reference frame, therefore can also carry out check groups with this characteristic Whether multicast data frame is to meet the information frame for making protocol specification by oneself.

It can be seen that can be received by sender's transmission by above-mentioned sub-step all referring to frame and information frame.

Step S22, the configuration information is extracted from two editable field possessed by the multicast packet frame.

As previously mentioned, there are two editable field for multicast packet frame tool, it is destination address domain and its frame ontology domain, purpose respectively Address field is used for load information with its low 23 editable bit area, and frame ontology domain is with the spy of its length and the reference frame The binary format difference load information of number is positioned, therefore, this step is by extracting the two editable field in information frame Information can be used to the coded sequence for assembling the configuration information.

Specifically, referring to Fig. 7, this step is by following specific sub-step processing:

Step 221: extracted from two editable field of each multicast packet frame for being confirmed as information frame sequence and The index string to put in order for characterizing the sequence constitutes coding unit.

Specifically, out of, coding unit expressed by its destination address domain is extracted in the information frame first part Hold, remaining of the coding unit is determined with the frame length difference of information frame and the binary format of the particular number of bits of the reference frame Partial content obtains the complete coding unit.

The essence of this step is the decoded process of execution part, relatively only in each information frame its object is to obtain The vertical coding unit.

As recipient, the coding principle in accordance with sender is needed, therefore, four kinds of coding staffs listed by corresponding former approach For formula, the information frame received for institute will be decoded as follows:

The first corresponding decoding process:

From the editable bit area in the destination address domain of information frame, i.e., its low 23, therefrom extract index string (first 6) With the first subcode string (latter 17) of sequence, then, then frame length (or the respectively frame sheet of the information frame and the reference frame is sought Body length of field) between binary system difference (3), i.e. the second subcode string mutually concatenates the first subcode string with the second subcode string, i.e., Sequence is constituted, and indexes string and is subsequently used for the sequence characterized with it to determine the assembling sequence of sequence.The sequence and rope of acquisition Draw string, just constitutes the coding unit being loaded into the information frame.

Corresponding second of decoding process:

Similarly, to extract entire sequence from editable bit area i.e. its low 23 in the destination address domain of information frame (low 20) and the first subindex string (before editable bit area 3) gone here and there is indexed, then with the frame length of the information frame and the reference frame Binary system difference (3) between degree (or respectively frame ontology length of field) determine the second subindex string of index string, by the first son Index string splices with the second subindex string goes here and there up to entire index, and index string just constitutes volume expressed by the information frame with the sequence Code unit.

The third corresponding decoding process:

It is relatively simple herein, directly the editable bit area in the destination address domain in information frame is extracted for 23 totally, i.e., The sequence is obtained, by the binary system between the information frame and the frame length (or respectively frame ontology length of field) of the reference frame Difference (3 or more) is determined directly as index string, and index string just constitutes corresponding coding unit with sequence.

Corresponding 4th kind of decoding process:

Similarly with the third decoding process, directly the editable bit area in the destination address domain in information frame is mentioned for 23 totally Take out, that is, obtain the index string, by the frame length (or respectively frame ontology length of field) of the information frame and the reference frame it Between binary system difference (3 or more) be determined directly as sequence, index string just constitutes corresponding coding unit with sequence.

As it can be seen that, regardless of its details, not taking off agreement mechanism corresponding with cataloged procedure in this sub-step.It is held Capable principle is that first part's content of coding unit expressed by its destination address domain is extracted from information frame, and with the letter The frame length difference (binary format of limit length) of breath frame and the reference frame determines in the rest part of the coding unit Hold, to obtain the complete coding unit.

When all information frames are decoded the coding unit, the preliminary decoder of entire information is just completed, after Continuous need to complete splicing and reduction process and can obtain corresponding information.

Step S222, characterized according to the index string in each coding unit sequence, by the sequence of all coding units Sequentially it is spliced into coded sequence.

Since each coding unit all has the index string of the characterization sequence of itself, this index string is to indicate each volume The sorting position locating when decoupling coded sequence of sequence possessed by code unit.Thus, by each coding unit according to its tool The characterized sequence of some index strings sequentially assembles corresponding sequence, can restore a corresponding coded sequence, It can be used to restore the information transmitted.

Step S223, coded sequence is reduced to the configuration information.

As previously mentioned, if the coded sequence is sequence obtained by the ciphertext conversion formed after encrypting information, Need for the coded sequence to be first reduced to ciphertext, recycle prestored secret key by the ciphertext decrypt it is described transmitted with confidence Breath.As for the type of the key, then depending on encryption technology is public key encryption or symmetric cryptography, for the former, using with The corresponding private key that prestores of public key when coding is decrypted, and for the latter, is decrypted using prestored secret key identical with key when coding. Certainly, if the coded sequence is non-encryption information conversion and is obtained, this processing need not be passed through.

As previously mentioned, the configuration information is generally to merge multiple information elements by certain format group in coding A coded sequence is converted to, for example it is assumed that the information restored carries out the bit string formed after ASCII character conversion (character string) content is as follows:

SSID:MYWiFi|PSW:PLZLOGIN。

As can be seen that SSID therein and PSW printed words, are the type identification of information element, MYWiFi is with PLZLOGIN The particular content of information element, attribute separator, that is, colon ": " is for partition type mark and particular content, element separator " | " is for separating different information elements.Smart machine according to making the specification of agreement by oneself, according to above-mentioned principle to the bit string into Row parsing, can realize the conversion and interpretation to configuration information, obtain the configuration information, finally enable smart machine accordingly Configuration own net is arranged and accesses target network.

It should be noted that above steps on one side can know it with flexible approach, one side receiving multicast data frame Not and decoding, can also be after whole multicast packet frames have received, then be decoded respectively.Those skilled in the art should know this one Mechanism.

Step S23, configuration is executed with the configuration information and completes the access target network.

After obtaining the configuration information, just obtain control of intelligent terminal provide service set (SSID) and accordingly Password, smart machine can determine corresponding SSID, and it is corresponding password that the password, which is arranged, carries out a series of shake hands Process, until establishing the connection with WiFi AP representated by the SSID.

After smart machine connects the AP, target network has just been accessed, can theoretically have been communicated with cloud server, can also have been passed through The routing function that current local area network provides is communicated with the control of intelligent terminal in net.To which, smart machine can be to The control of intelligent terminal sends one and characterizes the signal for having completed network insertion, so that control of intelligent terminal can be mentioned further Subsequent operation is done to user for operation control interface.

As it can be seen that networking cut-in method of the invention, corresponding with former approach, realized by simple step, Ji Keshi The extraction for the information that now multicast packet frame is loaded, and be not necessarily dependent on recipient and recipient be stably connected with build It is vertical, it quickly controlled can network.

Further, modularized thoughts are based on, the present invention provides a kind of control of intelligent terminal above-mentioned, preferably, the intelligence Controlling terminal is mounted with the mobile phone of aforementioned corresponding APP to realize.

Referring to Fig. 8, the control of intelligent terminal includes obtaining in an exemplary embodiments of control of intelligent terminal of the invention Unit 11, processing unit 12, signal transmission unit 13 and operating unit 14 are taken, discloses the function that each unit is realized in detail below Can:

The acquiring unit 11, display user interface, which is used to obtain, makes matching for the smart machine access target network Confidence breath.

By taking android system as an example, mobile phone passes through acquiring unit 11 first and calls and show a movable component (Activity), it or one page realized using HTML5 of display, shows the user interface on the screen and scans WiFi access-in point information (is enumerated) with service set SSID, requests user's selected target network, and requires user's input corresponding Password, to obtain the SSID and password of target network.

As details accommodation, after user has selected SSID, acquiring unit 11 can be inquired to cloud server should Password corresponding to SSID can save the operation for requiring user to input target network password if password exists.

The processing unit 12, for the configuration information to be encoded to each multicast packet in multiple multicast packet frames Two editable field possessed by frame.

It after obtaining the configuration information, needs to encode the configuration information using processing unit 12, forms frame Data.For this purpose, referring to Fig. 9, the processing unit 12 specifically include coding split cells 121, reference frame structural unit 122 with And information frame structural unit 123, the processing unit 12 is constructed by the function that these units are realized.

The coding split cells 121, for the corresponding coded sequence of the configuration information to be separated into multiple sequences, Defining each sequence and the respective index string of the characterization indexed sequential for its distribution is coding unit.

SSID:MYWiFi|PSW:MYLOGIN。

The coded sequence is converted into binary system acquisition based on the above-mentioned format string of configuration information.In order to Keep configuration information safer, coding split cells 121 can first encrypt configuration information (above-mentioned character string), be formed close The coded sequence is reconverted into after text.The mode of encryption either public key encryption, is also possible to symmetric key encryption, As long as receiving end can be decrypted using corresponding key (the same key in private key or symmetric cryptography in such as public key encryption) ?.Either encryption or disclosed state after configuration information is resolved to binary code, encode split cells 121 It is encoded, is adapted to be assigned in each multicast packet frame.

Firstly, the coded sequence of configuration information is separated into several sequences by coding split cells 121, each sequence is constituted Relatively independent and a part without informative, is expressed, such as occupy 20 bits with same length.It then, is each A sequence distributes an index string, this sequence similarly also uses binary expression, occupies such as 6 bits, the format of 6 bits Under, it can be used to express 2⁶Group sequence.Then, the index string described for each sequence group unification, goes here and there according to index Numerical values recited, the proper sequence of the sequence can be expressed, i.e., the sequence isolated of coded sequence is by its concatenation Index string of corresponding size is sequentially matched, the index string is made to can be used for expressing the indexed sequential of sequence corresponding thereto i.e. It can.The partition and sequence of entire coded sequence are completed therefrom.Wherein, be the convenience illustrated, by each index go here and there and with its group The sequence of conjunction is defined as a coding unit, then configuration information is just separated into multiple coding units, and each coding unit is opposite It is independent, but be ordered between each other.It should be noted that coding unit itself is a combined concept, rather than a sequence Fixed concept.In order to realize the utilization to multicast packet frame, the total length of coding unit is determining totally 26 bit, the rope Draw string and occupies the first length therein totally 6 bits, and remaining second length, 20 bit is then to compile occupied by corresponding sequence The total length of code unit is exactly the sum of the first length and the second length.Obviously, all coding units are all having the same total Length.

The configuration information is encoded split cells 121 and is separated into after multiple coding units, can be based on multicast packet Frame carries out next code.

The reference frame structural unit 122 is configured as constructing reference frame based on multicast packet frame format, and initialization should Two editable field of reference frame are to determine benchmark.

The information frame structural unit 123 is configured as based on multicast packet frame format tectonic information frame, by each volume Code unit is divided into two parts content and is expressed in two editable field of a corresponding information frame respectively.

Similarly, the information frame is also to be constructed based on multicast packet frame.Information frame structural unit 123 constructs The process of the information frame is that each coding unit is respectively corresponded to the process for being encoded to an information frame.It is outlined below The several ways of encoding relation between each coding unit and information frame structure.

The first coding mode:

Second of coding mode:

The third coding mode:

4th kind of coding mode:

By the announcement of above four kinds of coding modes, could be aware that, anyway, the final structure of information frame structural unit 123 Information frame made of making, the editable bit area in one of two editable field, i.e. destination address domain, in particular to the domain, By first part's content comprising coding unit described in one, this partial content can be the whole or part of it of sequence Sequence is also possible to the whole or part of it subindex string of index string.And the frame length of the information frame, by its it is another can The adjustment of edit field, that is, frame ontology length of field makes its frame length with the reference frame there are the difference in a particular range, The binary format of this difference just contains the remainder not being encoded into the destination address domain in the coding unit Depending on point content, the type of this partial content and number type and number expressed by the destination address domain, either sequence Remainder subcode string, be also possible to whole sequences, can be index string whole or its remainder index string.Always It, the sequence and index string that same coding unit is included can depend on actual need and be discretely expressed in same information frame Among the frame length difference of destination address domain editable bit area and the information frame and the reference frame, the structure of the information frame is completed It makes.

After having executed function above-mentioned, that is, the entire cataloged procedure of the configuration information is realized, obtained corresponding Reference frame and information frame.

The signal transmission unit 13, for transmitting wirelessly the multicast packet frame, to start to smart machine Networked deployment.

The construction of the reference frame and information frame is completed, whole coding works of the configuration information are just completed, by This, calls the corresponding interface by signal transmission unit 13, can will be described using the WiFi communication component based on 802.11 agreements Reference frame and information frame are transferred to receiving end wirelessly to aerial radiation.It should be pointed out that since upper-layer protocol is With UDP work, so, the reference frame and information frame are sent with UDP message packet, since udp protocol is unreliable association View, thus, when transmitting the reference frame and information frame, set such as 10 times recycles signal transmission unit 13, in each circulation, The reference frame and information frame successively send according to the indexed sequential that index string list is levied to (reference frame, which is considered as, is encoded to 0 sequence the One), to ensure that receiving end smoothly receives whole multicast packet frames.Nevertheless, reference frame and information frame are in same one cycle Transmission sequence be also possible to out-of-order, have no effect on implementation result of the invention.It should be noted that time cycled through when transmission Number also should not be limited to optional network specific digit, can be more wheels transmission of such as 5 times, 20 other inferior data.

As can be seen that control of intelligent terminal has issued reference frame and information simply by the signal transmission unit 13 Frame, in case starting operates the networked deployment of smart machine, not configuration of the actual implementation to the network settings of Intelligent hardware, and Be by smart machine itself, using control of intelligent terminal transmission come networked deployment information go to realize, in this regard, art technology Personnel should be known photograph.

The operating unit 14, for providing the control for interacting with the smart machine for the smart machine after networking Operation interface processed.
