Description
Technical field
The present invention relates to coding method, is the digital coding method of vehicle identification code concretely.
Background technology
According to the definition of international standard ISO3779 and CNS GB16735, vehicle identification code (VIN code: VehicleIdentificationNumber) is to identify a certain car, is one group of character code that this vehicle is specified by Railway Car Plant.This identification code is the unique identities identifier of automobile product registration in the whole life cycle of vehicle, vehicle management department all needs to use vehicle identification code verifying vehicle, when identifying, therefore vehicle identification code can think that vehicle is unique, identity root information that is the most basic, that can show testing vehicle register.
Vehicle identification code contains manufacturer, age, vehicle, body model and code, the engine code of vehicle and assembles the information such as place, totally 17 character codes.
As shown in Figure 1, to the Railway Car Plant of complete vehicle and/or incomplete vehicle annual production >=500, the Part I of vehicle identification code is that manufactory of the world identifies code name (WMI); Part II is vehicle declaratives (VDS); Part III is vehicle indicating section (VIS).
As shown in Figure 2, to the Railway Car Plant of complete vehicle and/or incomplete vehicle annual production < 500, the Part I of vehicle identification code is that manufactory of the world identifies code name (WMI), and manufactory of the world identifies that the 3rd character code of code name is numeral 9; Part II is vehicle declaratives (VDS); Part III third and fourth, five form manufactory of the world and identify code name (WMI) together with three character code of Part I, all the other five is vehicle indicating section (VIS).
Vehicle identification code is as the unique identification marking of vehicle, be widely used in vehicle Life cycle, except the mechanisms such as automaker, dealer, traffic control department, quality supervision department carry out management can use vehicles, for car owner, apply also more, such as vehicle peccancy inquiry, after-sales service maintenance etc.
At present, the fixed form of vehicle identification code is mainly directly embedding being engraved on vehicle frame or with bar code fashion and is mounted on windshield inferior horn place, when needs carry out identification to vehicle, mainly by the mode such as manual identified, manual inscription rubbing.Although vehicle identification code also can adopt bar code form to indicate, it is still " Visual identification technology " in essence, namely can only identify in visual range, and easily damaged, pollute or come off and even illegally changed, environmental suitability is poor.And do not seek unity of standard in the home position of the vehicle identification code of different vehicle, each producer's self-defining, therefore current various relate to vehicle identification code in car activity poor efficiency and insecure recognition methods greatly hinder its application as automobile product identity root.
Along with the development of the technology such as the Internet, Internet of Things, O2O (off-line business model), people are no longer confined among physical dimension, and are shifted to information dimension in the life style of oneself, living space.Must realize automatically identifying the high level of identity of automobile in information dimension, the vehicle identification code of this non-electronicization that only can identify by artificial vision can not meet primary demand and efficient management mode to vehicle electric identification, relate to the numerous areas such as car application at present, therefore proposes active demand to the electronization of vehicle identification code.
The electronization of vehicle identification code needs to encode, by traditional ASCII coded system, each character needs 8bit binary number to represent, then the coding of 17 characters of vehicle identification code just needs 136bit, and be only 128bit in the size of minimum data differentiation block (general electronic products code area EPC) of the electronic storage mediums such as such as RFID, the vehicle identification code of ASCII coding can not be stored, and except vehicle identification code, usually also need to store other vehicle-related information, therefore more efficient digital coding method is needed, to adapt to electronic storage medium memory space in short supply, meet read when information dimension is applied consuming time short, decoded back is demand easily.
Summary of the invention
The invention provides a kind of digital coding method of vehicle identification code, to decrease the storage bit number of vehicle identification code to greatest extent, realize vehicle identification code digital coding memory space and minimize, and read consuming time short, decoded back is demand easily.
The digital coding method of vehicle identification code of the present invention, comprises step:
A. according to the manufacturer's attribute identified in vehicle identification code, in the data structure of described coding, the flag taking 1bit is set up; The vehicular manufacturer of such as annual production >=500 is set to binary zero, and the vehicular manufacturer that annual production < is 500 is set to binary one;
B. judge whether manufacturer's attribute bit of vehicle identification code compiles according to described flag, if manufacturer's attribute is the vehicular manufacturer of annual production < 500, then manufacturer's attribute bit is fixed as 9, therefore does not compile;
C. by the continuous number part in vehicle identification code, entirety carries out binary coding as a decimal number, and such as, when flag is " 0 ", last 5 of vehicle identification code is numeral entirely, owing to being to the maximum " 99999 ", takies 17bit after coding; When flag is " 1 ", last 3 of vehicle identification code is numeral entirely, owing to being to the maximum " 999 ", takies 10bit after coding, like this than directly saving very large space to individual digit ASCII coding;
D. all the other letters and independent numeral are carried out binary coding respectively;
E. by the binary code after all codings by its in vehicle identification code corresponding part order arrangement.
After like this vehicle identification code being encoded, memory space can distinguish the 128bit of block much smaller than the minimum data of general storage medium, and be also easy to decoded back after reading, the vehicular manufacturer of the < of annual production simultaneously 500, than vehicle identification code also few 1bit space of >=500 manufacturers, can save more clearance spaces for storing out of Memory.
Further, because the check digit of vehicle identification code is " 1 ~ 9 " or " X ", therefore the syndrome encoded can coming vehicle identification code by BCD (Binary-CodedDecimal) coded system, compiles it as the binary format of decimal number " 10 " when described check digit is " X ".Binary-coded decimal represents 0 ~ 9 in 1 decimal number with 4 bits, and " 10 " binary system that " X " is corresponding is 1010, is 4 binary systems equally, can saves more space like this.
Further, will the letter and number of encoding be needed in vehicle identification code to sort, each letter and number represents with the binary coding of the sequence number after sequence.English alphabet 26 altogether, sort for from 0 to 25, and minimum decimal number corresponding to letter in ASCII character is 65, and therefore carrying out binary coding to 0 to 25 can have less occupy-place.The numeral of 0 ~ 9 can letter sequence be then 26 ~ 35.Because same position both may be letter, also may be numeral, therefore maximum decimal number be 35, and being converted to binary system is 100011, only takies 6bit, taken up space after common ASCII encodes far less than directly being carried out by letter.
On this basis, when the check digit of vehicle identification code adopts BCD coding or other coded system, and when check digit is " X ", describedly do not comprise this check digit to letter sequence with to the binary coding of sequence number.
Preferably, 6bit is taken respectively, farthest to save footprint after letter and independent digital coding in steps d.
After tested, by above-mentioned coding method, the binary coding length of the vehicle identification code of annual production >=500 is reduced to 88bit, the binary coding length of the vehicle identification code that annual production < is 500 is reduced to 87bit, highly significant and reduce occupy-place quantity efficiently, for out of Memory has farthest saved memory space.
Coding method of the present invention, in conjunction with the difference of two kinds of forms of the composition of vehicle identification code, and take full advantage of the coding characteristic of character and numeral, by the integrated use of Multi-encoding mode, realize minimizing of vehicle identification code digital coding footprint, simultaneously it also can be made to read shortest time, and can decoded back very easily.
Below in conjunction with the embodiment of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following example.Without departing from the idea case in the present invention described above, the various replacement made according to ordinary skill knowledge and customary means or change, all should comprise within the scope of the invention.
