As shown in Fig. 2 vehicle electron identifying classification processing method flow chart in an embodiment of the present invention.Automotive electronics mark
Knowing classification processing method includes：
Step S1, determine strategy and obtain the tactful corresponding binary mask and binary system to compare code according to setting, it is described
Strategy is to the composite attribute in requisition for judgement at least including the first attribute.Strategy refers to the specific implementation for vehicle management
Behavior, as described above, than implementing to let pass such as whether opening specific vehicle banister, but be not limited thereto, specifically may be used also
So that including whether being dealt with the first opportunity to bus, whether track record is done to taxi, if to collecting congestion by vehicle
Take.The execution of strategy is typically conditional, and whether the multiple attributes mainly combined meet certain matched rule, multiple
Attribute specifically refers to identity information of vehicle etc., such as the license plate number of vehicle, type of vehicle, vehicle color, vehicle brand,
In actual judgement, it may only need to judge the single attribute as type of vehicle, it is also possible to comprehensive descision type of vehicle, car
Multiple attributes such as color, therefore composite attribute can include one or more attributes, i.e., at least including the first attribute.Binary system
Exactly judgement is compared according to certain matched rule to combinations thereof attribute in the effect that mask and binary system compare code, sets
Form and content with it is tactful mutually corresponding, will be described below.
Step S2, the binary message code read in vehicle electron identifying, the binary message code include generic field
And the corresponding identification field of composite attribute, the identification field correspondence is including being used for the first field of the first attribute of expression.Two enter
Information code processed is stored in a string of binary sequences in the memory headroom of vehicle electron identifying, can specifically use TID
（Tag ID, identify identifier）Code or EPC（Electronic Product Code, electric product coding）Code, for representing car
Various identity informations., it is necessary to illustrate, in actual applications for table by taking the binary message code of one 8 as an example
Show the corresponding identity information of multiple attributes, binary message code might have tens, but illustratively use herein 8 be for
The convenience of description.For example, binary message code is " 10100010 ", it is assumed that high five bit field " 10100 " is used to represent vehicle
Color color, low three bit field " 010 " is used for the type for representing vehicle, specifically, and " 001 " represents bus, and " 010 " represents to hire out
Car, " 011 " represents heavy truck.In the strategy of track record is done to taxi, it is only necessary to judge the type of vehicle, therefore car
Type be the first attribute in tactful corresponding composite attribute, and do not include other attributes.Accordingly in binary message
It is that the type of vehicle is represented by low three bit field in code " 10100010 ", and the vehicle color phase that high five bit field is represented
It is not relevant for for above-mentioned strategy.Therefore, binary message code division is recognized into field into generic field and identification field
The relevant field for each attribute being intended to indicate that in composite attribute, and generic field is relative to not table beyond identification field
Show the field of any attribute in composite attribute.In the present embodiment, high five bit field " 10100 " is generic field, low three
Field " 010 " is identification field, and low three bit field " 010 " is used to represent the corresponding vehicle class of the first attribute as the first field
Type.In more embodiments, it can also include being used to represent the second attribute in the identification field of binary message code
Second field, the first field and the second field be able to can also be spaced apart with continuously distributed, i.e. generic field and identification field phase
Between set, specifically according to binary message code form determine field set position.
Step S3, binary message code are with the binary mask step-by-step logical operation so that the binary message
Generic field is same in code is set to default value.The form of binary mask is set according to binary message code form, therefore
Binary message code is identical with the digit of binary mask.Both ensure common in binary message code by step-by-step logical operation
Field is uniformly set to default value, and generic field refers to the attribute that need not be judged in tactful corresponding matched rule as described above
Corresponding field or reserved field, therefore generic field is uniformly set into default value, are such as set to all ones or all zeroes, so can be with
By the uniform format of binary message code, to simplify the setting that binary system compares code.
In a particular embodiment, as shown in figure 3, step-by-step logical operation specifically includes step-by-step and computing and step-by-step or fortune
Calculate.Continue by taking above-mentioned eight-digit binary number information code " 10100010 " as an example, low three bit field " 010 " is identification field, for marking
Know the corresponding attribute of type of vehicle, and high five bit field " 10100 " is generic field, so needing generic field being set to acquiescence
Value.In the embodiment using step-by-step and computing, field corresponding with binary message code generic field in binary mask
It is set to full 0, i.e. high five bit field to binary mask to be filled with five 0, knows in binary mask with binary message code
The corresponding field of malapropism section is set to complete 1, i.e. low three bit field to binary mask and covered with three 1 fillings, therefore binary system
Code is " 00000111 " in the present embodiment.Step-by-step and two numbers for referring to participation computing, refer to binary message code respectively herein
And binary mask, each corresponding binary digit phase with, as long as corresponding two binary digits all be 1, as a result position just be 1,
Other situation result positions are 0.Therefore value of the binary message code after step-by-step logical operation is " 00000010 ", now commonly
Field is all changed into 0, and recognizes field and do not change.
It is corresponding with binary message code generic field in binary mask in the embodiment using step-by-step or computing
Field is set to complete 1, i.e. high five bit field to binary mask and filled with five 1, with binary message in binary mask
The corresponding field of code identification field is set to full 0, i.e., low three bit field to binary mask is filled with three 0, therefore two enter
Mask processed is " 11111000 " in the present embodiment.Step-by-step or two numbers for referring to participation computing, refer to binary system letter respectively herein
Code and binary mask are ceased, as long as at least one when being 1 in each corresponding binary digit phase or, corresponding two binary digits,
As a result position is just 1, and result position is just 0 when corresponding two binary digits are all 0.Therefore binary message code passes through step-by-step logic
Value after computing is " 11111010 ", and now generic field is all changed into 1, and recognizes field and do not change.
Binary message code after step-by-step logical operation be needs and binary system compare code between judgement is compared, two enter
The effect that system compares code is just intended to indicate that tactful corresponding matched rule, therefore different strategies has corresponding different two and entered
System compares code.Binary system compares the acquisition of code, can use numerous embodiments.For example, can in advance be deposited by database
Contain a variety of tactful corresponding binary systems and compare codes, it is determined that after corresponding strategy, in the corresponding binary system ratio of database lookup
To code, so that above-mentioned taxi does track record as an example, tactful content is that the driving trace of each taxi is kept a record, therefore
The rule of the corresponding matching of strategy is whether the type of vehicle is taxi, therefore is entered according to the requirement inquiry corresponding two of strategy
System compares code, code is compared by inquiring about acquisition binary system in the case of step-by-step and computing for " 00000010 ", in step-by-step or fortune
It is " 11111010 " that binary system, which compares code, in the case of calculation, is used when being compared in particular situations.In more embodiment party
In formula, the corresponding classification processing strategy in some position is single and is fixed, the strategy that for example plant area doorway banister is opened
Be it is stable, only be allow on-site vehicle enter, therefore binary system compare code be also it is relatively-stationary, can be directly prior
It is stored in the equipment such as radio-frequency identification reader/writer, is directly invoked when comparison is used.
It should be noted that step S1 obtains corresponding binary mask and binary system comparison code might not be in step S2
Completed before reading the binary message code in vehicle electron identifying, be i.e. absolute priority is not present between step S1 and step S2
Relation.In above-mentioned example, binary mask and binary system compare code and can set in advance, but in other cases
It is probably just to start to obtain corresponding binary mask machine two after the code of the binary message in vehicle electron identifying is read
System compares code, for example, when the radio-frequency identification reader/writer that some bayonet socket is set is being managed to vehicle, reading respectively on vehicle
Vehicle electron identifying after, it is therefore possible to use multiple task parallelisms perform multiple strategies, without being switched to during corresponding strategies, automobile
In electronic mark binary message code read, therefore step S1 can also upon step s 2 or step S1, step
Rapid S2 is carried out simultaneously.
Specifically, binary mask and binary system compare code and can also in real time generated according to matched rule, and binary system is covered
Code sets all ones or all zeroes as described above, relatively simple that is, in binary mask to the corresponding field of generic field, to identification field
Corresponding field sets full 0 or complete 1, and it is specifically determined in the way of step-by-step logical operation, to ensure to believe binary system
Generic field is uniformly set to default value in breath code.The generation of code is compared for binary system, is described in detail first as described above
Binary message code form, binary message code be used for represent multiple attributes and include may definition multiple reserved words
Section, multiple attributes include type of vehicle, vehicle color etc. as described above, and following table is by taking above-mentioned 8 binary messages code as an example.
Binary message code is that binary sequence is arranged according to certain rule, and the field of diverse location is used to represent not
The same meaning, is generally used to indicate that the attribute of corresponding vehicle identity information, due to being related to many kinds in actual application
Property, the content of upper table may more enrich.And the establishment of binary message code can also be pacified according to the field location described in upper table
Row is discharged into, start bit and offset by determining field etc. is determined.By taking low three bit field as an example, it can be drawn from upper table, it is low
Three bit fields are used to indicate that type of vehicle, so should write the binary code on type of vehicle in low three bit field.
During establishment, it should determine that the vehicle of vehicle electron identifying is installed first, what its type of vehicle is specifically, if
Taxi, searches following table and show that corresponding binary code is " 010 ", therefore can just be organized into binary code " 010 " low by three
In bit field.
The generation that binary system compares code is also similar to the above, or by taking the strategy that track record is done to taxi as an example, such as
The upper binary system compares code and is intended to indicate that tactful corresponding matched rule, and in this strategy, matched rule is plan
The object slightly performed must be that taxi, i.e. type of vehicle this attribute must be directed at taxi, and other attributes are careless.Therefore
When binary system comparison code is generated, with reference first to the form of the binary message code described in upper table, according to strategy correspondence need
The composite attribute to be judged corresponding field location determination in binary message code, specifically, in above-mentioned strategy,
What is represented in high five bit field is vehicle color attribute, and is not belonging to tactful corresponding matched rule, therefore is filled with default value,
Or all ones or all zeroes, the mode with specific reference to step-by-step logical operation determines, and low three need to be filled into taxi corresponding two and
Code processed, by search " 010 " can be filled into it is low three, binary system comparison code be can be " 00000010 " or
“11111010”.In more embodiments, object code is first determined before generation binary system compares code, object code is according to matching
It is regular first to generate " 010 " in low three bit field, then binary code generated by random manner in high five bit field.Summarize and
Say and be exactly, field corresponding with binary message code generic field is generated in binary code, object code at random in object code
Field corresponding with binary message code identification field generates the corresponding binary code of the composite attribute.Then, generate
Object code compare code with the corresponding binary system of binary mask step-by-step logical operation acquisition, it is specific using step-by-step with computing still
Step-by-step or computing are with reference to above-mentioned binary message code and the embodiment of binary mask step-by-step logical operation.
The binary mask and binary system of acquisition compare code can be with Reusability, because tactful corresponding contrast judgement can be with
In different time points, on different vehicles.Therefore a caching can be set, binary mask and binary system are compared into code
In the buffer, the content in caching controls storage by way of life cycle for storage.Life cycle can be defined as
Think to exceed life cycle when not calling again in the default time, the various strategies also or in caching stored are corresponding
Binary mask and binary system are compared to be thought to exceed life cycle when code exceedes predetermined number.When corresponding binary mask and
Binary system compares code and exceeds life cycle, is just removed from the cache.Such purpose done is, when corresponding binary mask
And binary system is when comparing code and exceeding life cycle, illustrate that the corresponding strategy of binary mask machine binary system comparison code is switched, can
Can in it is long-term without using state, therefore corresponding binary mask and binary system compare code and value be also not present, so can
To be deleted, the occupancy to caching is reduced., can it can in addition contain ensure that corresponding binary message code form etc. changes
To accomplish to update in time, the problem of reducing unnecessary.
Step S4, after step-by-step logical operation binary message code with the binary system compare code it is consistent when perform described in
Strategy.As described above, binary message code after step-by-step logical operation compares code-phase simultaneously with binary system, illustrate corresponding car
Meet the matched rule of corresponding strategies, now perform corresponding strategies, specifically can for corresponding vehicle registration driving trace,
Open the corresponding vehicle of banister clearance, charging etc. is carried out to correspondence vehicle.The alignments advantage of present embodiment is, no
Need to be used to represent that the field of attribute extracts analysis one by one in the binary message that will be got from vehicle electron identifying code,
It is complicated especially for tactful corresponding matched rule, and the processing that needs to classify vehicle it is various in the case of, extraction and analysis one by one
The time of occupancy and resource will be exaggerated, and may result in the burden in processing.And the binary mask and binary system obtained
Comparing can use directly to compare after code is disposably obtained in multiple matching, substantially increase efficiency.
As shown in figure 4, vehicle electron identifying specification processing system module map in an embodiment of the present invention.Automotive electronics mark
Knowing specification processing system includes initialization unit U1, reading unit U2, arithmetic element U3 and execution unit U4.
Initialization unit U1, for determining strategy and obtaining the tactful corresponding binary mask and two enter according to setting
System compares code, and the strategy is to the composite attribute in requisition for judgement at least including the first attribute.Such as vehicle electron identifying point
Described in class processing method embodiment, strategy is specific implementation behavior in vehicle management, such as letting pass banister, and each
Strategy execution again be whether achieved based on some condition premised on, actual conditions content is typically referred to testing vehicle register etc.
Judge, that is, represent whether one or more attributes of testing vehicle register meet preset value, one or more attributes here just refer to
Composite attribute at least including the first attribute.Initialization unit U1 is according to strategy to the composite attribute in requisition for judgement in institute
State corresponding field location generation binary mask and binary system in binary message code and compare code, if for example, binary system is believed
Low three bit field of breath code is used to representing the type of vehicle, and the type of vehicle is strategy to the attribute in requisition for judgement, therefore two
The binary code that low three bit field of system mask is set should be ensured that with not occurring after binary message code step-by-step logical operation
Change, and low three bit field that binary system compares code just should the binary system of filling Strategy correspondingly represented by the matching result of requirement
Code.In a preferred embodiment, the binary mask and binary system of generation are compared code and are stored in by initialization unit U1
To call in caching with life cycle, the binary mask and binary system beyond life cycle compare code, from described
Deleted in caching.It may be considered that beyond binary mask and binary system the comparison code of life cycle and be not used in automobile electricity in short term
Sub-mark classification processing is used, therefore can reduce occupancy by deleting.The corresponding binary mask of strategy and binary system are compared
Code is mainly used in contrast judgement, is obtained according to specific strategy, and specific embodiment is referred to vehicle electron identifying point
The embodiment of class processing method.
Reading unit U2, for reading the code of the binary message in vehicle electron identifying, the binary message code includes
Generic field and the corresponding identification field of composite attribute, the identification field correspondence include the first word for being used to represent the first attribute
Section.A string of binary sequences for representing testing vehicle register etc. that binary message code is stored in vehicle electron identifying, two
Binary information code includes multiple fields of correspondence different attribute, and according to tactful contrast judgement needs, multiple fields are generally divided again
For two kinds, one kind is identification field, i.e., with strategy to the corresponding field of composite attribute in requisition for judgement, another is exactly common
The corresponding field of attribute that field, i.e. strategy execution need not judge.Due to common word need not be used in deterministic process
The binary code represented in section, therefore certain place can be done to the generic field in binary message code by arithmetic element U3
Reason.
Arithmetic element U3, for binary message code with the binary mask step-by-step logical operation so that described two
Generic field is uniformly set to default value in binary information code.As shown in figure 3, arithmetic element U3 is specifically included：The binary system letter
Cease corresponding with binary message code generic field in code and the binary mask step-by-step and computing, the binary mask
Field be full 0, field corresponding with binary message code identification field is complete 1 in the binary mask.Step-by-step with
The generic field in binary message code after computing is all changed into 0, and recognizes that field does not become, and is classified with vehicle electron identifying
Exemplified by 8 binary messages code in processing method embodiment, " 10100010 " are by step-by-step with being changed into after computing
" 00000010 ", corresponding low three bit field of identification field is still " 010 ", and what correspondence was represented is the binary code of taxi.
Similarly, in arithmetic element U3, binary message code with binary mask can also step-by-step or computing, described two enter
With the corresponding field of binary message code generic field it is to enter in complete 1, the binary mask with described two in mask processed
Information code processed recognizes that the corresponding field of field is full 0.The generic field in binary message code after step-by-step or computing all becomes
For 1, and recognize that field does not become, equally by taking 8 binary messages codes as an example, " 10100010 " are changed into after step-by-step or computing
" 11111010 ", corresponding low three bit field of identification field is still " 010 ", and what correspondence was represented is the binary code of taxi, because
The composite attribute that this without prejudice to strategy correspondence judges.
Execution unit U4, for after step-by-step logical operation binary message code and the binary system compare code it is consistent when
Perform the strategy.Binary message code by step-by-step and after computing and binary system compare code compare it is referred to as positive match,
Code is compared with binary system by the binary message code after step-by-step or computing and compares referred to as negative relational matching mode.This matching is not
Need, to being used to represent that multiple fields of different attribute are extracted and analyzed one by one in binary message code, to make whole matching stream
Cheng Gengjia is easy, is coordinated by comparing code with binary mask and binary system, realizes and directly matches.Determined according to the result of matching
Whether the corresponding result of strategy performs, such as in the case of consistent, opens corresponding banister.
