The realization of coding

Two-dimensional bar code is widely applied to fields such as industry, commerce, national defence, communications and transportation, finance, health care, post and telecommunications and office automation as a kind of convenient and practical information acquiring technology.But the information capacity of traditional bar code is very little, more describes the support of the necessary dependency database of information of commodity, therefore uses and is subjected to certain restriction.Two-dimensional bar code then makes and contained a large amount of information in the finite space, has satisfied the needs that carry out the high density printing in the small size space.This function makes two-dimensional bar code itself just comprise the bulk information in the database, becomes portable data file, and it can be distinguished at any time, and needn't carry out just fulfiling assignment behind the database manipulation with main frame constantly.These functions are specially adapted to military field.

Lu Hang boat material 2-D barcode system selects for use the PDF417 bar code as the code system of making bar code, it is the portable data file of a kind of high density, high information content, is that the also desirable means of available machines used automatically identifying and reading are stored, carried to realization high capacity, high reliability information automatically.

According to coding standard and the existing boat material of Lu Hang management mode, the invention provides two kinds of coding methods, to satisfy different regulatory requirements:

One, presses the type piece number coding of equipment

1, presses the type piece number coding step of equipment

According to Lu Hang existing management system and use habit, encoding by the type piece number of equipment is to put in order by the type piece number to encode.With the Helicopter-11 helicopter is example, and concrete steps are as follows:

(1) the boat material information master database tables of data of setting up is carried out index by the type piece number.

(2) for guaranteeing the cryptoprinciple of one yard, one yard one thing of a thing, when situation about using on many airplanes for an equipment is encoded, the sign indicating number of only encoding.

When (3) in a plurality of structural members, using, only keep a record, unit is installed the number addition replace original value, separate merging afterwards with ", " between the diagram figure number and replace original figure number value for an equipment.Remaining is deleted.(23310AA015020L0 is at 62.20.11.02, and 62.20.15.01 occurs in the diagrams such as 62.30.11.01 as split pin, then figure number is " 62.20.11.02; 62.20.15.01,62.30.11.01 ", and it is that all these equipment units are installed the number sum that unit installs several 25.

(4) division of sign indicating number position, detailed catalogue district: initial code one boat in detailed catalogue district gets 0100, presses type piece number series arrangement; If the sign indicating number position is not enough, extendible new detailed catalogue district.

(5) according to the requirement of science coding, leave suitable idle bit district.For picture bolt, nut, screw, split pin and so on, these equipment models compare me, but specification is more approaching.During coding, the coding of these equipment is got successive value, how much stays corresponding idle bit district in the back of these records according to equipment quantity continuously then.What of idle bit area size and equipment quantity are identical.When many continuously, carry out staging treating (be 30 in principle and be recorded as a section) for bolt, nut.

(60 for about part, front and back part, this class equipment of upper and lower pieces, taking into account system, the coding of two records is continuous, but the room of staying for complement code is constant.Promptly the room district after two records is 4.

2, based on the encryption algorithm of fuzzy membership

The idle bit bit length is definite in the cataloged procedure, affects the life cycle of systematicness, continuity and the system of coding on certain program.It is oversize that the idle bit position is stayed, and spacing is long between the equipment code, lacks continuity.It is too short that the idle bit position is stayed, and when newly-increased equipment was too much, the idle bit position of reserving was not enough, in the time of just may complement code occurring the equipment code not in the sign indicating number district of affiliated structural member, thereby the systematicness of influence coding; On the other hand, when newly-increased equipment is too many, when the idle bit position very little can't complement code, can cause system to use, shorten the life cycle of coded system.

The frequency of equipment remodeling affects the length of idle bit position on large program very.Equipment will be retrofited and be mainly contained following factor and cause: equipment is relatively more expensive, needs to prolong the serviceable life of equipment, improves the service efficiency of equipment and retrofits; Equipment is in the force part, improve the resistance to compression, bending resistance, tension, fatigue resistance of equipment and retrofits; To the bigger equipment of helicopter (aircraft) performance impact, thereby the reliability that will improve equipment improves the performance of helicopter and retrofits; For some maintenanceability equipment,, improve the maintainability of equipment and remodeling etc. for convenience, the safety of keeping in repair.So get the remodeling possibility that " equipment expensive ", " equipment is in the force part ", " the equipment maintainability is poor ", " equipment is with high content of technology " four indexs are judged equipment.

Because equipment costliness, maintainability difference and technology content are high all to be uncertain, all can not provide accurate description, but the degree of membership in the fuzzy digit can address this problem well.

" equipment is expensive " can construct membership function, gets

Wherein A1 (x) is an equipment price when being ten thousand yuan of x, and equipment is the degree of membership of " expensive " equipment.

For " equipment is in the force part ", " the equipment maintainability is poor ", " equipment is with high content of technology " three indexs, can not weigh by quantity, adopt Comprehensive Evaluation.To these several indications, earlier provide the judge value by the expert, to the fluctuation of judge value bigger with mean value as with reference to value, carry out secondary or obtain and repeatedly pass judgment on until providing satisfied value (value for expendable part " the equipment maintainability is poor " gets 1).

In fuzzy digit, the method for multifactor commentary pattern-recognition mainly contains selects into principle.

Definition is provided with the binary function on the Г (U)

τ：Г(U)×Г(U)→[0，1]

(A，B)|→τ(A，B)????????????????????????(2)

If τ satisfies

(1)τ(A，A)＝1，τ(Φ，U)＝0；

(2)τ(A，B)＝τ(B，A)； $\left(3\right)A\⊆B\⊆C\⇒\mathrm{\τ}(A,C)\≤\mathrm{\τ}(A,B)^\mathrm{\τ}(B,C)$

Claim that then τ is the approach degree function on the Г (U), claim that (A B) is the approach degree of A and B to τ.

Select approximately principle, establish A _i∈ Г (U), i=1,2 ... n, A={A ¹... A ⁿ) constitute a master pattern storehouse, for the B ∈ Г (U) that waits identification, if i ∈ 1,2 ..., n} makes $\mathrm{\τ}(B,A^i)=\underset{1\≤j\≤n}{\max }\mathrm{\τ}(B,A^j)----\left(3\right)$

Claim that then B presses close to A most in A under the τ meaning ⁱ, B gets relatively in A and makes A in other words ⁱ

Set up equipment remodeling possibility indicator vector as showing:

Structure approach degree function is

τ wherein _j(A ^j, B) be the equipment to be evaluated and the approach degree of j type of equipment

A (x _Ij) be I desired value of j kind equipment.

B (x _i) be I desired value of equipment to be evaluated. $\mathrm{\τ}(B,\mathrm{Ai})=\underset{1\≤j\≤n}{\max }\mathrm{\τ}(B,A^j)----\left(5\right)$

Then the possibility of equipment remodeling is A ⁱClass.

The possibility of known equipment remodeling according to the possibility parameter, is determined the idle bit section length of staying behind the equipment.The reason of newly-increased equipment is similar with equipment remodeling, the idle bit section length behind the structural member also thus method carry out.

With reference now to Fig. 1, the flow process of encoding by the type piece number is described.

At step S1, pointer is positioned at article one record, initial code N is made as " 0100 ".At step S2, the basic storehouse of current equipment and other types of having encoded is compared, judge whether to exist this equipment, if exist, at step S3, then the code of current equipment is got coder material code, otherwise at step S4, the detailed catalogue sign indicating number of this equipment is got 0100, bits of coded N adds idle bit section length behind the equipment, step enters S5, navigates to next bar record, repeating step S2 to S4, enter step S6, judge whether it is the last item record, if then withdraw from; Otherwise repeating step S5.

Two, press system coding

Encode by system, encode according to the sequencing that structural relation between each parts and equipment occur in illustrated catalogue.Concrete steps are following with pressing type piece number coding.

The helicopter of same type (aircraft), a certain equipment uses on a plurality of structural members, and coding is only encoded once, and figure number is merged, and separates with ", " between each figure number.Requirement according to the science coding will leave suitable idle bit district.Idle bit is distinguished three parts and is reserved: behind each equipment, after each structural member, after each system, leave the idle bit position of certain-length respectively, go up newly-increased equipment complement code for helicopter (aircraft) and use.

The idle bit section length is determined after the system: the idle bit section length of staying behind each helicopter (aircraft) is mainly by this system's equipment total quantity decision, general and total quantity is linear, according to the characteristics that increased equipment newly in the past, the idle bit section length of staying after the system is got 10% of this system's equipment total quantity.Consider the systematicness of coding, the idle bit length of staying after system suitably enlarges, and makes next system begin to be encoded to 100 integral multiple.Be discharged to " 0331 " as sign indicating number position, detailed catalogue district after adding the idle bit position behind each part, the structural member, " air-conditioning system " detailed catalogue district, this system has 125 equipment, and 125 * 10%=12.5 is calculated in system idle bit position, gets 13, and the idle bit position is discharged to " 0344 ".When next chapter was encoded, initial detailed catalogue sign indicating number was got " 0400 ".

With reference now to Fig. 2, describes by the system coding process flow diagram.

At step S21, pointer is navigated to article one record of database; Judge in the master database that other have been encoded, whether there is this equipment at step S22; If exist, then enter step S23 the code of described equipment is got the code of coder material; Otherwise the idle bit section length replaces after entering step S24 the code of described equipment being added equipment with N; Then, navigate to next bar record, and judge in the master database of having encoded, whether there is this equipment at step S26 at step S25; If exist, then enter step S27, repeating step S23, and change step S29 over to; Otherwise enter step S28 and judge whether this equipment appears in the equipment of coding of same kind; If exist, then enter step S27 repeating step S23, and change step S30 over to; Otherwise the idle bit section length replaces after entering step S29 the code of described equipment being added equipment with N; Then, judge whether it is the last item record of structural member at step S30; If the idle bit section length replaces after step S31 adds structural member with the code of described equipment with N; Otherwise at step S31 repeating step S25 to S31; Then, judge whether it is the last item record of system at step S32; If enter step S33 if then code area (idle bit district) length behind the code usefulness N adding system of described equipment is replaced, and get 100 multiple downwards; Otherwise enter then repeating step S25 to S32 of step S34; Then, judge whether it is the last item record at step S35; If not, enter step S36 if not, repeating step S25 to S35 then.

With reference now to Fig. 3, the formation of two-dimensional bar system is described.

The two-dimensional bar system comprises bar code generating apparatus 1, is used for the multidate information of input is encoded, and generates two-dimensional bar; Memory storage 2 is used to store the two-dimensional bar that is generated; Bar code printing device 3 is printed the two-dimensional bar information that is generated; Bar code identifying device 4, the two-dimensional bar information that generated of identification, and with identifying information and database mate, verification and obtain other relevant information; Bar code harvester 5 is used for Information Monitoring; Interface arrangement 6 provides dynamic link library, and with the information of the being gathered described input media that writes direct, thereby " seamless " between the realization system connects.Wherein this system can also comprise the bar code encryption device, and the two-dimensional bar information that is generated is encrypted.This system can also comprise error correction device, and multistage error-correction level is set, and is convenient to normally discern bar code.

Here said two-dimensional bar code shape comprises information labels and two kinds of forms of index tab, is to be index, to comprise the two-dimensional bar of all information of Lu Hang boat material with boat material code.The device that is used to print bar code can adopt the PRODIGY bar code dedicated printer and the general laser printer of DATAMAT company.The recognizer of Shi Yonging is selected the online end of scan of LS4804 and the PPT2800 handheld terminal of U.S. symbol company for use in the present invention, also can adopt other scanister.Can directly use the computing machine in the existing business management system to realize the two-dimensional bar system, this computing machine should have the dual serial expansion interface.Recognition device adopts the RS-232 serial interface circuit with communicating by letter of described intercomputer.
