The specific embodiment of invention is described in detail.
Fig. 1 is a kind of flow chart of coding method in the embodiment of the present invention, and the coding method can include step S11 extremely
S13：
Step S11：According to the multiple communication systems for being used for transmission data to be transmitted, the equal energy of the multiple communication system is obtained
The universal character of identification.
Step S12：At least a portion in the universal character is chosen as base character, based on the base character structure
Mutually different code word is built, to obtain a yard storehouse, different code words corresponds to different characters.
Step S13：The data to be transmitted is encoded using the code storehouse.
In the specific implementation of step S11, the equal universal character that can be identified of the multiple communication system, such as can be more
The coding mode that a communication system is converted to the universal character binary bit stream is identical, i.e., same universal character exists
There is identical binary bit stream, and the universal character is equal in the multiple communication system in the multiple communication system
It is not endowed with special meaning.
It specifically, can be according to the communication system belonging to the sender and recipient that are used for transmission data to be transmitted, two
Character intersection is chosen in the character set of a communication system, and then excludes identical characters in character intersection but there are different meanings
Situation, so as to obtain the universal character in above-mentioned two system.
It further, then can be described when needing to add in the 3rd communication system as sender or recipient
On the basis of character intersection, with reference to the character set of the 3rd communication system, the general words in three communication systems are further chosen
Symbol.
Preferably, can be based on common multiple communication systems, choose the multiple communication system can identify it is general
Character from regardless of which communication system sender and the recipient of transmission data to be transmitted belong to, can be used described general
The code word of character structure is transmitted, without choosing universal character again.It specifically, can be in printable ASCII words
It is chosen in symbol and meets all of network address coding rule, Quick Response Code coding rule, mail coding rule and short message encoding rule simultaneously
The intersection of code character, formation can adapt to be manually entered, print, the transmission of network address parameter, Quick Response Code coding, mail transmission and short
Believe the Unified coding character set of transmission.
Wherein, ASCII (American Standard Code for Information
Interchange, ASCII) it is single byte coded system most general now, use 7 binary bit streams (remaining 1
Binary system is 0) to represent English upper and lower case letter, Arabic numerals 0 to 9, punctuation mark and is used in Americanese
Special controlling character.
During being chosen to ascii character, English upper and lower case letter, Arabic numerals 0 to 9 can be considered each
The universal character that can be unambiguously identified in a communication system, i.e., the coding staff for any one character therein being passed through into sender
Formula is converted to binary bit stream, and after being transmitted to and belonging to the recipient of another communication system, the coding that recipient passes through one's own side
The binary bit stream received still can be converted to the character rather than other characters by mode, be known so as to fulfill correct
Not.
In the specific implementation of step S12, at least a portion in the universal character is chosen as base character, is based on
The base character builds mutually different code word, and to obtain a yard storehouse, different code words corresponds to different characters.
Wherein, for carrying the code word of information to be transmitted built by base character, and different code words corresponds to
Different characters.Specifically, code word can include a base character, can also include multiple base characters, code word and code word
Between be differentiable.
In specific implementation, the code word in code storehouse is converted into binary bit stream in order to realize, and then realizes physical layer
Transmission, should realize that code word covers the binary number of a byte or two bytes in coding, so that each binary number can
It is replaced with different code words.
It is understood that the base character that each code word includes cannot be very few, because the primary word that each code word includes
Fu Yue is few, and it is more to cover the required code word of identical content.Specifically, when the base character that each code word includes is one
When, it is necessary to 256 code words could cover the state sum of the binary number of a byte, i.e. the 256 of 8 bits kind state,
Further, it is necessary to 256*256=65536 code word could cover the binary number of two bytes state sum, i.e., 16 two
65536 kinds of states of system number.When the base character that each code word includes be two when, it is necessary to which 16 code words could cover a word
The state sum of the binary number of section is, it is necessary to which 256 code words could cover the state sum of the binary number of two bytes.When each
, it is necessary to which 7 code words can cover the state sum of the binary number of a byte, i.e. 7* when the base character that code word includes is three
7*7=343>256, it is necessary to which 41 code words can cover the state sum of the binary number of two bytes, i.e. 41*41*41=68921
>65536。
In specific implementation, can be based on each code word includes two base characters, to cover the binary number of a byte,
Or each code word includes the situation structure code word of three or more base characters.As previously mentioned, in order to realize in each communication system
It can unambiguously be identified in system, universal character is selected from English upper and lower case letter, Arabic numerals 0 to 9, totally 62 characters.I.e.
The optional scope of base character is 62 universal characters.
It is understood that the base character that each code word includes cannot be excessive, because the primary word that each code word includes
Fu Yue is more, and the occupied transfer resource of character for transmitting each data to be transmitted is more.
Preferably, it can use and be more than or equal to 41 mutually different code words of base characters structure, wherein each code word includes 3
A base character can cover the state sum of the binary number of two bytes.It is equivalent to and is covered using 1.5 base characters
The binary number of one byte, the transfer resource of occupancy will be less than in the case that each code word includes 2 base characters, using 2
A base character covers the binary number of a byte.
Using the embodiment of the present invention, 41 base characters can be more than or equal to by selecting, so that the code word in code storehouse is total
The state sum of the binary number of number two bytes of covering, is replaced identical so as to fulfill the code word formed using minimum base character
The binary number of number, further improves communication efficiency.
It is highly preferred that the general words chosen from the Arabic numerals and English upper and lower case letter of the multiple communication systems of compatibility
Fu Zhong filters out the most common character in the character and text easily mutually obscured, and obtains 41 preferred base characters, bag
It includes：1、2、3、4、5、6、7、8、9、B、D、F、G、H、J、K、M、P、Q、U、V、W、X、Y、Z、b、d、f、g、h、j、k、m、p、q、u、v、
w、x、y、z.It can be reduced using above-mentioned preferred base character composition code word and be manually entered error rate.
