Order of magnitude c 0 0 0 1 1 1 2 2 2 3 3 3
It should be noted that what the corresponding relation of the value of above radix b, order of magnitude c and enumerator provided for the present embodiment A kind of optimal way, in the specific implementation, first the radix radix to be not limiting enumerator initialization value 1 correspondence is searched In first radix in table, or an order of magnitude order of magnitude to be look-up table of enumerator initialization value 1 correspondence An order of magnitude；Such as, when the value of enumerator is 1, first radix corresponding with the value 1 of enumerator in radix look-up table is permissible Being second radix in radix look-up table, after the value of enumerator adds 1, in radix look-up table, the value 2 with nonce counter is right The next radix answered is the 3rd radix in radix look-up table, the like, when the value of enumerator increases to 11, corresponding Radix be the 12nd radix in radix look-up table.Radix b, number can be set situation according to the actual requirements when being embodied as The corresponding relation of the value of magnitude c and enumerator, the above table of the present embodiment it is preferred that.
The described denomination information contingency table being pre-configured with that accesses according to described denomination information, acquisition and described denomination information The denomination coding joined, specifically includes:
Judging whether described order of magnitude c is not less than carry value d preset, wherein, carry value d is preferably 4, the most then give birth to The carry coding becoming numerical value to be X, and generate basis order of magnitude e, wherein, e=c-d；Compile if it is not, then generate the carry that numerical value is Y Code, and generate basis order of magnitude e, wherein, e=c；Preferably, encoding with binary number representation, X can be 1, and Y can be 0；
The value of enumerator is initialized as 1；
From described radix look-up table, obtain first radix corresponding with the value of described enumerator, enter with described radix b Row contrast；
An order of magnitude corresponding with the value of described enumerator is obtained, with described basis from described order of magnitude look-up table Order of magnitude e contrasts；
If the radix obtained from described radix look-up table differs with described radix b, and/or searches from the described order of magnitude The order of magnitude obtained in table differs with described basis order of magnitude e, then make the value of described enumerator add 1, search from described radix Table obtains next radix contrast with described radix b, and obtain from described order of magnitude look-up table the next order of magnitude with The order of magnitude e contrast of described basis；
If the radix obtained from described radix look-up table is identical with described radix b, and from described order of magnitude look-up table The order of magnitude obtained is identical with described basis order of magnitude e, then take denomination coding based on the value of presently described enumerator；
After described carry coding and described basis denomination coded combination, it is thus achieved that the denomination coding of described denomination information.
As a example by the banknote that denomination value is 100, the process that denomination encodes is described: its radix b=1, order of magnitude c=2, due to C ＜ d, therefore carry is encoded to Y=0, basis order of magnitude e=c=2；When the value of enumerator is 1, due in radix look-up table First radix corresponding with the value 1 of enumerator is 1, and the first number corresponding with the value 1 of enumerator in order of magnitude look-up table Magnitude is 0, and the order of magnitude i.e. obtained from order of magnitude look-up table differs with basis order of magnitude e, therefore makes the value of enumerator add 1, continue executing with contrast coupling；During until the value of enumerator is 7, the radix obtained in radix look-up table is 1, order of magnitude look-up table The order of magnitude of middle acquisition is that 2, now radix b and order of magnitude c all contrast that the match is successful, and the value 7 of nonce counter is base surface Volume encodes, and is expressed as 0111 with tetrad, combines with carry coding, and the denomination that i.e. can get described denomination information is compiled Code.
Currency type coding also can use binary number representation with version coding, if representing currency type with eight bit, then can prop up Hold up to 256 currency types, substantially be enough to represent most currency types in the whole world at present；Version coding can be with triad number table Show；Assume that the banknote that this denomination is 100 yuan is the RMB third edition, the currency type coding that in currency type information association table, RMB is corresponding Being 00000001, the version that in version information contingency table, the third edition is corresponding is encoded to 011, then the currency type that can obtain this banknote is compiled Code is 00000001, and version is encoded to 011.
It should be noted that by described carry coding and described basis denomination coded combination, it is thus achieved that described denomination information The meaning represented by denomination coding is that denomination coding can be summarized as carry coding and the combination of described basis denomination coding, does not limit Determining carry coding and described basis denomination coding will be for order combination successively in the form of final coding output.Carry is compiled Code, basis denomination coding, currency type coding and version encode assembled arrangement in any order, belong to the scope of protection of the invention.
As a example by 100 yuan of banknotes of the RMB third edition, its information coding such as following table sequential combination can finally export one 2 The coding binary information 0000000100110111 of byte (hexadecimal output coding result is: 0x0137):
As a example by the banknote that denomination value is 10000, the process of its denomination coding is as follows: radix b=1, order of magnitude c=4, by In c=d, therefore carry is encoded to X=1, basis order of magnitude e=c-d=0；When enumerator is 1, due in radix look-up table First radix corresponding with the value 1 of enumerator is 1, and the first number corresponding with the value 1 of enumerator in order of magnitude look-up table Magnitude is 0, i.e. takes denomination coding based on the value 1 of nonce counter, is expressed as 0001 with tetrad.As can be seen here, Denomination information is converted into the cardinal sum order of magnitude, omits some uncommon cardinal sum orders of magnitude, the data of reduction denomination coding While amount, encode by arranging carry, in the case of the order of magnitude number of order of magnitude look-up table is certain, codified can be expanded The denomination scope of value document so that it is can have valency to beyond the big of maximum number magnitude in order of magnitude look-up table seeking scope File also can encode.
In order to improve compatibility and practicality, the described denomination information of the value document information coding method that the present invention provides Contingency table also includes special denomination look-up table；Described special denomination look-up table includes multinomial specific coding information, and each item is special Coding information includes currency type coding, one particular number level of a special cardinal sum, and each specific coding information pair Ying Yuyi special denomination coding；
The described denomination information contingency table being pre-configured with that accesses according to described denomination information, acquisition and described denomination information The denomination coding joined, may further comprise:
When the value of described enumerator is M, still without when obtaining described basis denomination coding, then search from described special denomination The specific coding letter that in table, inquiry and the currency type of described value document encode, radix b and basis order of magnitude e matches Breath, it is thus achieved that the special denomination corresponding to described specific coding information encodes, using as described basis denomination coding.At the present embodiment In, M is preferably the maximum of enumerator, and M=N1=N2=12.In other embodiments, M can be arbitrary value, than As, the maximum of enumerator may be configured as 100, and M could be arranged to 16, when the value of enumerator is M=16, described still without obtaining During the denomination coding of basis, then accessing special denomination look-up table, the situation with specific reference to actual demand is arranged.
Some special denominations, i.e. radix are not belonging to the value document of common radix, can look into by inquiring about special denomination Look for table to obtain basis denomination coding, further increase the compatibility of the value document information coding method that the present invention provides.With Time introduce currency type and encode as foundation the information tabled look-up so that different currency types, the value document of difference denomination can use together One basis denomination coding, only need to combine parsing when decoding with currency type coding can distinguish, and reduces basis denomination further and compiles The data volume of code.
As a example by the banknote of 0.25 yuan of Kuwait, it is assumed that the currency type of Kuwait is encoded to 93 (hexadecimal is 5D), this paper money The radix b=25 of ticket, order of magnitude c=-2, basis order of magnitude e=-2, carry is encoded to 0, due to radix look-up table and the order of magnitude Look-up table does not has this radix 25 and the order of magnitude-2, therefore when the value of computer is added to M=12 (maximum), still cannot be right The match is successful for ratio, then inquire about special denomination look-up table according to currency type coding 93, radix 25, the order of magnitude-2, if special denomination is searched In table, the special denomination of this specific coding information corresponding is encoded to 13, then the basic denomination of this banknote is encoded to 13 (16 enter It is made as D).
On the south 25 yuan of the Sudan banknote as a example by, it is assumed that south the Sudan currency type be encoded to 185 (hexadecimal is B9), this banknote Radix b=25, order of magnitude c=0, basis order of magnitude e=0, carry is encoded to 0, owing to not having this radix 25 and the order of magnitude 0 The situation of the value of corresponding same enumerator, therefore when the value of computer is added to M=12, still cannot contrast that the match is successful, then Special denomination look-up table is inquired about according to currency type coding 185, radix 25, the order of magnitude 0, if this spy corresponding in special denomination look-up table The special denomination of different coding information is encoded to 13, then the basic denomination of this banknote is encoded to 13 (hexadecimal is D).
By two above example it can be seen that the value document of different denomination uses same basis denomination coding, by In introducing the currency type coding element as special denomination look-up table, the method for this mutual foundation denomination coding is not result in compiling and solves Code is made mistakes.If searching special denomination contingency table according only to the cardinal sum order of magnitude, and different denomination using same basis denomination If coding, arise that a basic denomination encodes the situation of corresponding multiple cardinal sum orders of magnitude when decoding, cause decoding Abnormal；And introduce the currency type coding foundation of tabling look-up as special denomination look-up table, when setting up special denomination look-up table, as long as protecting Demonstrate,prove same currency type, the value document of different denomination uses different basic denomination codings, when decoding just can according to currency type coding with Basis denomination coding accurately searches the corresponding cardinal sum order of magnitude.
Different currency types, the value document of different denomination use same basis denomination coding to be beneficial in that, each The special denomination that currency type comprises is few, and the most special basic denomination encoded radio is typically within 4, and the maximum of enumerator is 12, therefore basis denomination encoded radio has 16 can meet demand, it is only necessary to tetrad can represent 16 basic denominations Coding, reduces data volume.
