Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Fig. 1 is the compression method flow chart of the terminal reported data of the embodiment of the present invention, as shown in Figure 1, the method packet
It includes：
Step S01, the data to be transferred of preset length is read, the data to be transferred is made of code word arrangements.
Transmitting terminal first obtains the data to be transferred for being ready for sending receiving terminal, which passes through arrangement by a large amount of code word
Composition, and length can be set according to the actual needs, such as 1024 bytes, wherein the size of the code word can also root
It is set according to actual needs, such as one or two byte length.
Step S02, according to preset contractive condition, the data to be transferred is divided into according to putting in order for the code word
At least one phrase, the phrase include at least type of coding and coding information.
The data to be transferred is traversed according to the sequencing of code word arrangements, one by one will according to preset contractive condition
The data to be transferred is divided into multiple phrases, and the phrase includes at least a code word, and has to the definition of each phrase corresponding
Type of coding.The coding information of each phrase can also be obtained according to contractive condition.
Further, the type of coding is uncompressed coding, identical coding or matching coding；Wherein, the identical volume
Code and matching are encoded to compressible coding, and correspondingly, the contractive condition is specially：
If the code word for forming the phrase is an identical code word, the type of coding of the phrase is identical coding,
And the coding information of the phrase includes at least phrase length, an identical code word；
If there is code word group identical with the permutation and combination of code word in the phrase in the data to be transferred before the phrase
It closes, then the type of coding of the phrase is that matching encodes, and the coding information of the phrase includes at least phrase length, described short
Language and the offset of identical code word combination apart；
And the type of coding of other phrases is uncompressed coding, and the coding information of the phrase includes at least described in composition
All code words of phrase.
Wherein for the mode classification of type of coding can there are many kinds of, also only with one such in the embodiment of the present invention
Mode is illustrated.
The type of coding can be divided into uncompressed coding and compressible coding, wherein compressible coding is divided into as identical volume
Code and matching coding.
Wherein, the phrase contractive condition to be met of the identical coding is：The code word for forming the phrase is identical
One code word, and then the coding information of the phrase then includes at least phrase length and forms an identical code for the phrase
Word, such as phrase " aaa " are made of 3 code words ' a ', then the type of coding of the phrase is identical coding, and coding information is phrase
Length 3, code word ' a '.
It is described matching coding the phrase contractive condition to be met be：In data to be transferred before the phrase, i.e.,
It completes to exist in the data to be transferred of segmentation and there is the code word combination that aligned identical combines, the code word group with code word in the phrase
Conjunction is not required for being attributed to same phrase.And then the phrase coding information include at least phrase length, the phrase with it is described
The offset of code word combination apart.
And the contractive condition of identical coding had both been unsatisfactory in the data to be transferred, also it is unsatisfactory for the compressor bar of matching coding
The phrase of part may be defined as uncompressed coding, and the coding information of such phrase includes at least all code words of the phrase.
It, then, can be with according to above-mentioned contractive condition for example, data to be transferred is " abcdaaaabcdefbbbbbbbbcdefgh "
The data to be transferred is split from front to back：Wherein,
The type of phrase " abcd " is uncompressed coding, and coding information is ' a ', ' b ', ' c ' and ' d '；Phrase " aaaa "
For identical coding, coding information is phrase length 4, code word ' a '；
Phrase " bcd " in data to be transferred before due to that can find identical code word combination " bcd ", so the phrase
It is encoded for matching, coding information is phrase length 3, offset 7；
Phrase " ef " is unsatisfactory for the contractive condition of identical coding and matching coding, and the described phrase is uncompressed coding,
Coding information is ' e ' and ' f '；
Phrase " bbbbbbbb " is identical coding, and coding information is phrase length 8, code word ' b '；
Phrase " cdef " is that matching encodes, and coding information is phrase length 4, offset 12；
Phrase " gh " is uncompressed coding, and coding information is ' g ' and ' h '.
Step S03, it according to the coding information of corresponding with the type of coding coding rule and each phrase, obtains and institute
State the corresponding coding segment of phrase；Wherein, if the type of coding is compressible coding, according to the static code table to prestore to phase
The coding information for the phrase answered carries out compressed encoding to obtain the coding segment of the phrase.
After the type of coding for obtaining each phrase can according to the coding rule corresponding with each type of coding that prestores,
The coding information of each phrase is encoded to obtain coding segment.Wherein, if the type of coding is compressible coding,
It needs according to the static code table to prestore come the phrase length or offset progress compressed encoding in the coding information to phrase, to obtain
Coding segment corresponding with the phrase.
Step S04, according to each phrase, putting in order in the data to be transferred will be after corresponding coding fragment combination
It is sent to receiving terminal, so that the receiving terminal will be every according to decoding corresponding with coding rule rule and the static code table
A coding segment resolves to corresponding phrase, and the data to be transferred is obtained after combination.
After obtaining the corresponding coding segment of each phrase, so that it may with first according to arrangement of the phrase in the data to be transferred
Corresponding coding segment is combined by sequence afterwards, is then sent to receiving terminal.
The receiving terminal is advised after the combination for receiving the coding segment according to decoding corresponding with the coding rule
Then and the static code table, the coding segment is identified and is parsed, to obtain the corresponding phrase of each coding segment.
There is phrase to be sequentially combined by described, so that it may to obtain the data to be transferred.
The data to be transferred is divided into multiple phrases by the embodiment of the present invention by the traversal to the data to be transferred, and
The fast and effective compressed encoding that obtains is carried out to obtain corresponding coded slice to each phrase according to the type of coding of each phrase respectively
Section, is then then forwarded to receiving terminal, so that receiving terminal thus greatly reduces data by obtaining the data to be transferred after decoding
The complexity of compressing data in transmission process, accelerates the speed of compression, reduces the consumption of resource.
Based on above-described embodiment, further, the coding rule, specially：
If the type of coding is uncompressed coding, corresponding coding segment is each code word in the coding information
It is preceding to increase uncompressed code identification；
If the type of coding is identical coding, corresponding coding segment includes identical code identification, equal length code
With an identical code word；Wherein, the equal length code is the phrase length in the coding information according to corresponding phrase
It is obtained by the static code table；
It is encoded if the type of coding is matching, corresponding coding segment includes offset code and matching length code；Wherein,
The offset code and matching length code respectively according in the coding information of corresponding phrase offset and phrase length pass through it is described
Static code table obtains.
Coding rule in above-described embodiment can be set according to the actual needs, in the embodiment of the present invention
Only it is to give one such illustration.
If the type of coding is uncompressed coding, corresponding coding segment is each code word in the coding information
The preceding mark for increasing uncompressed coding, for example, the coding segment of the phrase " abcd " of uncompressed coding is { 0'a', 0'b', 0'
C', 0'd'}, wherein 0 is a uncompressed code identification.Correspondingly, it is in the decoding rule of receiving terminal, if in coding segment
Start bit is 0, then can directly judge that the latter code word is the code word in uncompressed coded phrase, parse successively in the phrase
All code words.
If the type of coding be identical coding, corresponding coding segment by identical code identification, equal length code and
The identical code word composition, wherein the equal length code is that the phrase in the coding information according to corresponding phrase is long
Degree checks in the static code table.For example, the coding information of the phrase " aaaa " of identical coding is phrase length 4, code word
' a ', the identical code identification is 10000, and the corresponding equal length code in static code table of phrase length 4 is 0001, then
The coding segment of the phrase is { 100000001'a'}.Correspondingly, it is in the decoding rule of receiving terminal, if coding segment is opened
Beginning position is 1, then can be determined that corresponding type of coding is identical coding or matching coding, then intercept four next, if obtaining
10000, then can be determined that corresponding type of coding be identical coding, then intercept corresponding digit parse respectively phrase length with
And code word, to obtain corresponding phrase.
It is encoded if the type of coding is matching, corresponding coding segment is made of offset code and matching length code；Its
In, the offset code and matching length code pass through institute according to the offset and phrase length that correspond in phrase in coding information respectively
Static code table is stated to inquire.For example, the phrase " bcd " of matching coding, wherein offset are 7, and code word size 3, the offset
The corresponding offset code in static code table of amount 7 is 101011, and the corresponding matching length code in static code table of phrase length 3 is
00, last coding result is { 10101100 }.Correspondingly, it is in the decoding rule of receiving terminal, if the start bit of coding segment is
1, and intercept that obtain after four below is not 10000, then it can be determined that corresponding type of coding is that matching encodes, further according to quiet
State code table intercepts corresponding digit and parses offset and phrase length respectively, can be according to offset and phrase length
Corresponding code word combination is found in data to be transferred before parsing, to obtain corresponding phrase.
By taking data to be transferred " abcdaaaabcdefbbbbbbbbcdefgh " as an example, the coded slice of each phrase is respectively obtained
Section is as follows respectively：
By taking each code word is a byte as an example, then the length of data to be transferred is：27*8=216bits, and after encoding
Coding segment total length is 124bits, and compression ratio is：57.4%.
The static state code table can be the mapping table of a unified numerical value and coding segment, can also be according to equal length
Different mapping tables is respectively set in the difference of code, matching length code and offset code, or only two mapping tables mixing of setting make
With.For example, the static state code table can be divided into the first coding schedule and the second coding schedule, and equal length code and offset code are using the
One coding schedule, and matching length code uses the second coding schedule.It is described static state code table setting can come according to the actual needs into
Row, is not specifically limited herein.
Further, the phrase length of the identical coding and matching coding is not less than preset length threshold.
By above-described embodiment it is found that since identical coding and matching encode the volume for needing to be added more coding informations and obtaining
Chip segment is unable to reach the effect of optimization of compression if the phrase is too short.Need to pre-set length threshold thus, for example, 3 or
4, and according to contractive condition to the data to be transferred carry out traversal be divided into phrase when, it is ensured that it is identical coding and matching coding
Phrase length is not less than the length threshold, and all phrases less than the length threshold are defined as uncompressed coding.The length
Spend threshold value cannot it is too short can not be long, can be configured and adjust according to the actual needs, and can be respectively to identical
The length threshold different with matching encoding setting is encoded, is not specifically limited herein.
Correspondingly, when being encoded to the phrase length, can the phrase length first be subtracted into a length threshold,
Pass through the corresponding length code of static Codebook Lookup again.
Further, in the code length of the equal length code, matching length code and offset code and the coding information
The frequency height that corresponding numerical value occurs is related.
In order to further be compressed to the data, the equal length code, matching length code and offset
The constant that the code length of code is not to determine, for example, the equal length code of phrase length 4 is 0001 in above-described embodiment, and it is short
The equal length code of language length 8 is 01001, it is seen then that the code length of the equal length code can be according to corresponding numerical value not
Same and different, the matching length code and offset code are similarly such.The corresponding code length of common numerical value is contracted as far as possible
It is short, it can suitably be lengthened without common code length, it can the further compression ratio that must be improved to data to be transferred with this.
The data to be transferred is divided into multiple phrases by the embodiment of the present invention by the traversal to the data to be transferred, and
The fast and effective compressed encoding that obtains is carried out to obtain corresponding coded slice to each phrase according to the type of coding of each phrase respectively
Section, is then then forwarded to receiving terminal, so that receiving terminal thus greatly reduces data by obtaining the data to be transferred after decoding
The complexity of compressing data in transmission process, accelerates the speed of compression, reduces the consumption of resource.
