The specific data content for analyzing data to be transmitted, determines number to be transmitted according to the specific data content of data to be transmitted According to data type determine the T of data to be transmitted according to data type representated by T value predetermined in default TLV agreement Value determines the label thresholding of data to be transmitted；Wherein, determine that T value can be one according to the data type of data to be transmitted Or it is multiple, each T value has paired a L value and a V value.In a set of paired T value, L value and V value, V value table Show specific data content, T value indicates that the data type of V value, L value indicate the byte length of V value；Each V value can be again by T value, L value and the V value composition of multiple groups pairing.Wherein, T value is the numerical value that hexadecimal number indicates.Such as, it presets pre- in TLV agreement The T value first defined is hexadecimal " 1B ", represents the data type " age " of data to be transmitted；T value is hexadecimal " 1C ", generation The data type " gender " of table data to be transmitted.

Further, step S21 includes:

Step A10 determines the data type of the data to be transmitted according to default TLV agreement, and uses hexadecimal number It indicates the data type, obtains the first label thresholding；

According to default TLV agreement, the specific data content of data to be transmitted is analyzed, according to fixed in advance in default TLV agreement Data type representated by each T value of justice, the data class of data to be transmitted is determined according to the specific data content of data to be transmitted Type, selected from each T value predetermined in default TLV agreement T value corresponding with the data type of data to be transmitted as First label thresholding.Wherein, the first label thresholding, refer in default TLV agreement it is customized, for indicating data to be transmitted The hexadecimal values of data type.

Step A20, judge the data to be transmitted whether be the data type set；

In default TLV agreement, in order to make to indicate specific data content data type T value occupy byte as far as possible Reduction, do not include the identical data of two or more data types or data group as far as possible in a kind of definition of data type, keep away Exempting from the data type that combination is formed excessively causes the custom field of T value excessive, needs to occupy multiple bytes.If the area V needs The data to be transmitted are the identical data of multiple data types or data group, then the T value in the area T increases a mark to judge V Data are the identical data of the multiple data types of the identical data of data type or data group in area.Judge that data to be transmitted is wrapped The specific data content contained whether be data type set, that is, determine data to be transmitted included specific data content whether For the identical data of multiple data types or data group.Data type such as Fig. 5, the expression of three T values is completely the same, only will The T value of the data type of default TLV protocol definition is respectively as second T value, third T value, by default TLV agreement The T value of the data type of definition increases a mark and is used as first T value；So as to by identical two data of data type Or data group is encoded to a transmission data packet, is transmitted as a whole, and decoding group is combined into a set entirety.If Do not increase mark judgement in T value, then the subdata packet of two TLV formats in entire transmission data packet can only be split as Fig. 6 In shown in two transmission data packets, individually transmit, set entirety cannot be combined into when receiving decoding.

For example, the data type of data to be transmitted is transmission personal information " name, gender, age ", work as data to be transmitted For multiple people personal information when, need to transmit multiple " name, gender, ages ", then data to be transmitted is data to be transmitted The set of data type.

Step A30 will indicate the first label thresholding if the data to be transmitted is the set of the data type Byte extreme higher position 1, obtain the second label thresholding；

In default TLV agreement, we are defined, and in the byte for indicating T value (i.e. label thresholding), highest order does not represent symbol Position does not also represent numerical value, and remaining seven are used to indicate T value；When the expression byte highest order of T value is 1, data to be transmitted is indicated Gather for one, the identical data of transmission multi-group data type；When the expression byte highest order of T value is 0, one group of transmission is indicated The data of data type.

If data to be transmitted include the identical data of multi-group data type, can by by the expression byte of T value most High position 1 obtains the second label thresholding.Wherein, the second label thresholding obtains after referring to the expression byte extreme higher position 1 by T value Binary number.

If data to be transmitted is not the set of the data type of data to be transmitted, the specific number of data to be transmitted is analyzed According to content, the data type of data to be transmitted is determined according to the specific data content of data to be transmitted, and uses hexadecimal number The data type for indicating data to be transmitted, obtains the first label thresholding, by the first label thresholding directly as data to be transmitted Then label thresholding is counted that is, using the label thresholding of data to be transmitted as the T value in the area T of the transmission data packet of TLV format According to transmission.

The second label thresholding is converted to hexadecimal representation, obtains the label of the data to be transmitted by step A40 Thresholding.

Second label thresholding of binary number representation, which is converted to hexadecimal number, to be indicated, to obtain data to be transmitted Then label thresholding carries out data using the label thresholding of data to be transmitted as the T value in the area T of the transmission data packet of TLV format Transmission.

In the present embodiment, increase a mark in T value to judge that data are multiple for the identical data of data type in the area V The identical data of data type or data group, so as to which the data of multiple same types or data group are encoded to same transmission Data packet is transmitted.It avoids the data of multiple same types or data group from being respectively formed multiple transmission data packets individually to transmit, Cause multiple data of same data type or data group that cannot form a data acquisition system transmission.Meanwhile when the area V needs to transmit Data when being the identical data of multiple data types or data group, judge data in the area V by increasing mark in T value For the identical data of the multiple data types of the identical data of data type or data group, the data type of specific data content is indicated T value occupy byte reduce as far as possible, without increase T value occupied by byte, improve message data to a certain extent Efficiency of transmission.

Step S22 indicates the byte length of the data to be transmitted using hexadecimal number according to default TLV agreement, with Obtain the length thresholding of the data to be transmitted；

The specific data content for analyzing data to be transmitted is analyzed to be transmitted according to the specific data content of data to be transmitted Byte length shared by the content thresholding of data, then shared by the content thresholding using hexadecimal number expression data to be transmitted Byte length obtains the L value of data to be transmitted to get the length thresholding of data to be transmitted is arrived.Wherein, according to data to be transmitted The L value that byte length shared by content thresholding determines can be one or more, and each L value has a paired T Value and a V value.Wherein, L value is the numerical value that hexadecimal number indicates.

Step S23 indicates the data to be transmitted using hexadecimal number according to default TLV agreement, with obtain it is described to Transmit the content thresholding of label thresholding and length thresholding described in every group in data；

In a set of paired T value, L value and V value, V value indicates specific data content, and T value indicates the data type of V value, L Value indicates the byte length of V value；V value can nested multiple TLV formats subdata packet, i.e., each V value can be again by multiple groups T value, L value and the V value composition of pairing.According to default TLV agreement, data to be transmitted is indicated using hexadecimal number.Then ten six Data to be transmitted after system number expression determines the V value in the T value, L value and V value of each group pairing of data to be transmitted, that is, determines The content thresholding of every group of label thresholding and length thresholding in data to be transmitted.Wherein, V value is the numerical value that hexadecimal number indicates.

Further, step S23 includes:

Step B1 indicates the data to be transmitted using hexadecimal number according to default TLV agreement；

Such as Fig. 4, outermost V value represents the full content of data to be transmitted, each V value that outermost V value is included The data for respectively representing each attribute of full content, according to the T value and V value and L of each attribute of default TLV protocol definition Value, the data of each attribute are gone out using hexadecimal representation.

Step B2 determines each thresholding group using the label thresholding of pairing and length thresholding as a thresholding group Nested layer level；

Wherein, the label thresholding and length thresholding of pairing refers to that the label thresholding represents the data attribute of certain data, then. For example, data to be transmitted is that " age, 16 " indicate that the label thresholding at " age " is 01, indicate that byte length shared by " 16 " is 1, i.e. length thresholding is 1；Then label thresholding 01 and length thresholding 1 are pairing thresholding group.Nested layer level refers to a set of paired T In value, L value and V value, the subdata packet of the nested multiple TLV formats of V value, i.e., T value, L value and the V that each V value is matched by multiple groups again Value composition.Using the label thresholding of pairing and length thresholding as a thresholding group, determine that multiple groups nested in each thresholding group are matched Pair T value, L value and V value.As data to be transmitted be " user information, gender, female, the age, 16, height, 168 ", can be by " property Not, female " indicates that wherein T value (01), L value (01) indicate one using a set of paired T value (01), L value (01) and V value (01) " gender " thresholding group；" age, 16 " using a set of paired T values (02), L value (01) and V value (01) expression, wherein T value (02), L value (01) indicates " age " thresholding group；" height, 168 " using a set of paired T value (03), L value (01) and V value (01) It indicates, wherein T value (03), L value (01) indicate " height " thresholding group；Then the T value, L value and V value of three groups of pairings constitute one Outermost layer V value 010101020101030101, " user information " is using a set of paired T value (01), L value (01) and outermost layer V Being worth (010101020101030101) indicates, wherein T value (01), L value (01) indicate " user information " thresholding group.

Step B3, according to preset nested layer level traversal order, by the data to be transmitted that hexadecimal number indicates configure to Each thresholding group, to obtain the content thresholding of each thresholding group in the data to be transmitted.

According to the nested layer level of preset nested layer level traversal order and each thresholding group, by hexadecimal number indicate Data to be transmitted configures one group of T value, L value and the V value matched to each nested layer level.

For convenience of understanding, the example for meeting above step B2 is continued to explain；According to preset nested layer level traversal order, by ten The data to be transmitted that senary number indicates is configured to each thresholding group, respectively obtains the content thresholding of " gender " thresholding group, i.e. V It is worth (01)；The content thresholding of " age " thresholding group, i.e. V value (01)；The content thresholding of " height " thresholding group, i.e. V value (01).

In the present embodiment, data to be transmitted is encoded by way of nested layer level, so that a data packet can To accommodate more data, so as to disposably transmit required data, the transmission of message data is improved to a certain extent Efficiency.

The label thresholding, length thresholding and content thresholding assembly coding are hexadecimal TLV format by step S24 Transmission data packet.

By being put into the data packet of TLV format for data to be transmitted, specifically, the T value of data to be transmitted is put into TLV lattice The V value of data to be transmitted is put in the area T of the data packet of formula, the area L that the L value of data to be transmitted is put into the data packet of TLV format Enter the area V of the data packet of TLV format；I.e. by the label thresholding of data to be transmitted, the length thresholding of data to be transmitted and to be passed The content thresholding of transmission of data is sequentially placed into the area T, the area L, the area V of the data packet of TLV format；To which coding forms hexadecimal TLV The transmission data packet of format.

In the present embodiment, data to be transmitted is encoded by using default TLV agreement, cataloged procedure is by benchmark Data are indicated using the default customized T value of TLV agreement and V value, so that the transmission data packet formed is numerical value, Er Feiji Quasi- data greatly reduce the occupied byte of transmission data packet, to greatly improve efficiency of transmission.By using ten Senary indicates T value, L value and V value, and the number of T value, L value and V value can be made more succinct.

Further, in data transmission method 3rd embodiment of the present invention, Fig. 3 the embodiment described, step S22 are based on Include:

Step B10 is indicated the byte length of the content thresholding using hexadecimal number, obtained according to default TLV agreement First length thresholding；

According to default TLV agreement, byte length shared by the content thresholding in the area V is indicated using hexadecimal number, obtains the One length thresholding, what the first length thresholding indicated is the real bytes length in the area V.Specifically, content thresholding accounts for a byte Then byte length is 1, and content thresholding accounts for N number of byte, and then byte length is N；By byte length shared by content thresholding with 16 into Number processed indicates.Wherein, the first length thresholding refers to byte number shared by the content thresholding indicated using hexadecimal number.

Step C20, judges whether byte number shared by the first length thresholding is greater than predetermined word joint number；

One byte is 8, maximum in binary system are as follows: 11111111, it is equal to the decimal system 128.In default TLV agreement In, we define, and in each byte for indicating L value (i.e. length thresholding), highest order does not represent sign bit and do not represent numerical value yet, remain Yu Qiwei is used to indicate L value；So it is 0~127, corresponding 16 that the denotable V section length range of a byte, which corresponds to the decimal system, The L value of system is 0~7F.So the L value that a byte can indicate is up to 7F, when L value is more than or equal to hexadecimal 80 When, range can be indicated by having exceeded a byte, and needing to increase a byte (needing two bytes) indicates hexadecimal L value 80.First determine whether the shared byte number of first length thresholding itself is greater than predetermined word joint number, if the first length thresholding sheet Byte number shared by body is greater than predetermined word joint number, then proves that predetermined word joint number cannot completely indicate of the first length thresholding itself Size；If the shared byte number of first length thresholding itself is less than or equal to predetermined word joint number, prove that predetermined word joint number can Completely to indicate size of the first length thresholding itself.Wherein, in invention the present embodiment, predetermined word joint number is 1.

Step C30, if byte number shared by the first length thresholding is greater than predetermined word joint number, increasing indicates described the The byte number of one length thresholding, until the first length thresholding complete representation, to obtain the length thresholding of the data to be transmitted.

If the shared byte number of first length thresholding itself is greater than predetermined word joint number, prove that predetermined word joint number cannot be complete Size of whole expression the first length thresholding itself, needs to increase byte representation the first length thresholding.Further, first is calculated The shared byte number of length thresholding itself, then increases corresponding byte number, and the first length thresholding is carried out using each byte It indicates and by the extreme higher position 1 of newly-increased byte, is added after the data after each byte representation are then converted to hexadecimal Obtain the length thresholding of data to be transmitted.Specifically, when expression the area V byte length shared by byte number be greater than predetermined word joint number When, byte number shared by the area V byte length is expressed by newly-increased byte, i.e., newly-increased byte finally transmits data packet L to express The L value in area.

In the present embodiment, when expressing byte number shared by the area V byte length greater than predetermined word joint number, pass through added word Section is to express byte number shared by the area V byte length, to express the L value in the final transmission area data packet L, root by increasing byte newly The expression byte in the newly-increased area L is determined whether according to the area V byte length, so that the expression byte in the area L is reduced as far as, will pass The size of transmission of data packet controls in minimum zone, improves the efficiency of transmission of data.It avoids using unified reserved byte The L value in several expression areas L, when the area V byte length is smaller, unified reserved byte number is excessive to cause byte redundancy；When the area V word When section length is larger, too small is unable to complete of unified reserved byte number indicates the area V byte length.

Further, step C30 includes:

Step C31 increases the byte for indicating the first length thresholding, until the first length thresholding complete representation, obtains Indicate the target byte of the first length thresholding；

If the shared byte number of first length thresholding itself is greater than predetermined word joint number, prove that preset byte cannot be complete Expression the first length thresholding size itself, need to increase byte representation the first length thresholding.Firstly, calculating expression first Byte number shared by length thresholding, newly-increased byte number needed for then determining, to obtain indicating the target of the first length thresholding Byte.In particular it is required that increased byte number, which is equal to calculate, indicates that byte number shared by the first length thresholding subtracts predetermined word Joint number.Such as, the first length thresholding is hexadecimal 80, then it represents that byte number shared by hexadecimal 80 is 2, and hexadecimal 80 is used 2 byte representations are as follows: 10,000,001 01111111.

Wherein, target byte refers to each byte for indicating the first length thresholding.

Step C32 uses the target word by the extreme higher position 1 of each newly-increased byte, and by the first length thresholding Section indicates, obtains the second length thresholding；

Each highest order of newly-increased byte for indicating the first length thresholding is set 1, in the extreme higher position of preset byte 0, Then the first length of binary representation thresholding is used using target byte, to obtain the second length thresholding.Wherein, target byte Highest order be 1 to indicate below there are one the first length of byte representation thresholding, the highest order of target byte is 0 to represent and indicate the The byte of one length thresholding leaves it at that, below without the byte of the first length thresholding of expression.Second length thresholding, refers to and uses mesh The first length of byte representation thresholding is marked, and by the binary number behind each newly-increased byte extreme higher position 1.

For example, the first length thresholding is hexadecimal FE, being calculated indicates byte number 3 shared by the first length thresholding, It then needs to increase 2 bytes, 3 byte representations of hexadecimal FE are as follows: 10,000,001 11,111,111 01111111 newly.Wherein, it increases newly The highest orders of two bytes set 1, the highest order of target byte is 1 to indicate that there are one the first length fields of byte representation below Value, the highest order of target byte are that 0 byte for representing the first length thresholding of expression leaves it at that, below without indicating the first length The byte of thresholding.

Step C33, the second length thresholding, which is converted to hexadecimal number, to be indicated, obtains the length of the data to be transmitted Spend thresholding.

Second length thresholding of binary number representation, which is converted to hexadecimal number, to be indicated, to obtain data to be transmitted Then length thresholding carries out data using the length thresholding of data to be transmitted as the L value in the area L of the transmission data packet of TLV format Transmission.

In the present embodiment, when expressing byte number shared by the area V byte length greater than predetermined word joint number, pass through added word Section is to express byte number shared by the area V byte length, to express the L value in the final transmission area data packet L by increasing byte newly, and By the extreme higher position 1 of newly-increased byte, so that while completely inerrably expressing the area V byte length, it can basis in decoding Indicate that the highest order of byte determines the area L range.Increase the expression byte in the area L newly by way of the extreme higher position 1 by newly-increased byte, Newly-increased byte can be determined whether according to the area V byte length, so that the expression byte in the area L is reduced as far as, will transmit The size of data packet controls in minimum zone, improves the efficiency of transmission of data.It avoids using unified reserved byte number The expression area L L value, when the area V byte length is smaller, unified reserved byte number is excessive to cause byte redundancy；When the area V byte When length is larger, too small be unable to complete of unified reserved byte number indicates the area V byte length.

Further, after step C20 further include:

Step C40, if byte number shared by the first length thresholding is less than or equal to predetermined word joint number, by described the Length thresholding of the one length thresholding as the data to be transmitted.

If the shared byte number of first length thresholding itself is less than or equal to predetermined word joint number, predetermined word joint number is proved Itself size that can completely indicate the first length thresholding does not need to increase the first length of byte representation thresholding.Then, first is long Degree thresholding is the length thresholding of data to be transmitted, directly using the length thresholding of data to be transmitted as the transmission number of TLV format L value according to the area L of packet carries out data transmission.

In the present embodiment, when expressing byte number shared by the area V byte length less than or equal to predetermined word joint number, the area L Expression byte of the preset byte as the area V byte length is directlyed adopt, the byte without increasing the area L occupies the area L most Few byte number can indicate the area V byte length, reduce the byte number of data packet to a certain extent, to reduce data The size of packet improves the efficiency of transmission of data.The L value for avoiding the expression area L using unified reserved byte number, when the area V When byte length is smaller, unified reserved byte number is excessive to cause byte redundancy.

Further, in data transmission method fourth embodiment of the present invention, data transmission method further include:

Step D1 receives the transmission data packet of transmitting terminal transmission；

Data to be transmitted will form transmission data packet by coding is carried out according to default TLV agreement in transmitting terminal, then will Transmission data packet is transmitted to receiving end waiting.Termination to be received receives the transmission data packet of transmitting terminal transmission.

Step D2 determines label thresholding, length thresholding and the content domain of the transmission data packet according to default TLV agreement Value；

After termination to be received receives the transmission data packet of transmitting terminal transmission, go out to transmit data according to default TLV protocal analysis The T value in the area Bao Zhong T transmits the label thresholding of data packet；The L value for analyzing the area L in transmission data packet, that is, transmit data packet Length thresholding；The V value for analyzing the area V in transmission data packet, that is, transmit the content thresholding of data packet.Further, V value can be embedding The subdata packet for covering multiple TLV formats determines T value, L value and the V value of the multiple groups pairing that each V value includes.

Wherein, label thresholding refers to that the T value in the area T in the data packet of TLV format, each type of the area V data content are corresponding One customized T value, i.e., each label thresholding correspond to a kind of data type.

After termination to be received receives transmission data packet, go out to transmit the T value in the area T in data packet according to default TLV protocal analysis； And data type representated by T value predetermined in default TLV agreement is compareed, determine T value (the i.e. label field of transmission data packet Value) representated by the area V data content type (i.e. transmission data packet transmission data type).Every type of the area V data content Type corresponds to a customized T value, i.e., each label thresholding corresponds to a kind of data type.Data type refers to V in data packet The type or attribute of area's data content；Such as, the area V data content is " female " in data packet, and corresponding data type is " gender "；Number It is " 35 " according to Bao Zhong V area's data content, corresponding data type is " age ".

Step D3 determines the number of the transmission data packet transmission according to the label thresholding, length thresholding and content thresholding According to content.

It is true from the label thresholding of transmission data packet according to data type representated by T value predetermined in default TLV agreement Determine data type.The byte length of the area V data content is determined from the length thresholding of transmission data packet.According in default TLV agreement Data type representated by T value predetermined, every kind of data type number representated by V value predetermined in default TLV agreement According to content, and according to the byte length of the determining area the V data content of length thresholding, determined from the content thresholding of transmission data packet The area V data content, so that decoding obtains data to be transmitted.

Specifically, if including the subdata packet of multiple TLV formats in the area V, according to above-mentioned decoding process by each subdata Data content in packet, which decodes, to be come, and the data content of multiple subdata packets forms the message data of an entire data packet.

For convenience of understanding, the example connect in step S20 below is illustrated.Referring to Fig. 4, data to be transmitted is through default TLV Protocol code forms transmission data packet: 01090101010201B2030146, and the entire area T for transmitting data packet is that " 01 " is as whole The label thresholding of a transmission data packet, may know that transmission data packet transmission by label thresholding " 01 " is pair of User type As corresponding content.The area L of entire transmission data packet is the length thresholding that " 09 " entirely transmits data packet, indicates entire transmission The byte length in the area V of data packet is 9.The area V of entire transmission data packet is made of the subdata packet of three TLV formats, wherein In the subdata packet of first TLV format, the area T be " 01 " be first TLV format subdata packet label thresholding, pass through What label thresholding " 01 " may know that transmission data packet transmission is the corresponding content of " gender " attribute type；The area L is " 01 ", is indicated The byte length in the area V of the subdata packet of first TLV format is 1；The area V is the content thresholding that " 01 " transmits data packet, table Show " male " that " 01 " represents in " gender " attribute type；According to label thresholding, the length field of the subdata packet of first TLV format Value and content thresholding, obtain data to be transmitted are as follows: " gender " is " male ".Similarly, from the subdata packet of second TLV format Data to be transmitted out are as follows: " height " is " 178 ", obtains data to be transmitted from the subdata packet of third TLV format are as follows: " body Weight " is " 70 ", and the full content of data to be transmitted can be obtained by decoding entire transmission packet content.

In the present embodiment, it is decoded by will be transmitted to the transmission data packet of receiving end waiting according to default TLV agreement Data to be transmitted is obtained, so that receiving end waiting can receive to obtain the specific data content that transmission data packet is included, to protect Card data are completely inerrably transmitted.
