In order to technical solutions according to the invention are described, illustrate below by specific embodiment.
Embodiment one
Fig. 1 shows the flow chart of a kind of key manufacturing method that first embodiment of the invention provides, and details are as follows:
Step S11, generating initial code according to the key code parameter that pre-sets, described key code parameter includes: select the classification of key, the tooth number of key, the tartar of total several types, generate coding always go here and there number, coding group to be generated and coding file name.
In this step, described initial code is to utilize the multiple key code parameters pre-set to generate corresponding coding, it is made up of many height coding, each height has encoded corresponding function, each height coding can be with independent assortment, the number of the key code parameter that described initial code generally uses is between 6 to 16, such as, the tooth number of one bilateral internal layer key is 10, there is the coding of 4 types, the coded strings number needing to generate is set, select to generate the group of coding, after name preserves key code file name, the coding required for saltation layer can be generated.Generate the form such as " .2312431223 " of coded strings, " .1321431243 ".The parameter that different keys generates coding is different, and described key code parameter includes:
Select key classification: be divided into monolateral or bilateral, i.e. key be single tartar for monolateral, key be double tartar for bilateral；
The tooth number of key: the number of a tartar on the key, namely the number of teeth of key；
The tartar of total several types: the kind of a key tooth flower (or differential)；
Generate coding always goes here and there number: need the sum of the coding generated；
Coding group to be generated: from generating the coding group selecting to need to use group；
Coding file name: the file name of the key code that name preserves.
Step S12, screening and meet the key code of default screening conditions in described initial code one by one, described default screening conditions include: match grade before and after between sum that the tartar of tooth number of the same race is adjacent, tooth number, monolateral have several differ tartar, bilateral have several differ tartar, at least difference, the minimum extreme difference of monolateral tooth number, coding tooth mode the most symmetrical, fixing and any amount combination of fixing tooth position and number of a pair in any two string encodings.
In this step, described screening one by one meets the key code of default screening conditions particularly as follows: according to described default screening conditions in described initial code, from the beginning of the first son coding of described initial code, screen the son coding meeting default screening conditions in described initial code, combine all son codings meeting default screening conditions in order and obtain key code.

Match grade before and after between tooth number: limit the scope of phase adjacent teeth number, prevent tartar change in size scope excessive, as being set to 2 herein, then coding " .2312431223 " meets the requirements, coding " .2312412223 " is undesirable, in coding " .2312412223 ", 41 is adjacent, and it is 3 that grade is joined in district, is unsatisfactory for condition.Each two adjacent encoder in coded strings is required for meeting this condition；
Monolateral have several tartar differed: when the key of processing is monolateral key, the most several different tartar sizes in coded strings；
Bilateral have several tartar differed: when the key of processing is bilateral key, the most several different tartar size in every limit in coded strings；
At least difference of a pair in any two string encodings: with in numerous codings of a key, appoints and takes two string encodings and regarded as two integers, need to ensure certain difference after subtracting each other；
The minimum of monolateral tooth number is differential: in the coded strings of monolateral key, any two coding needs to ensure that certain difference, the coded strings of bilateral key need the coding ensureing both sides all to ensure there is certain difference.So parameter is set to 3, and coding " .2312431223 " meets the requirements, and coding " .2312312223 " is undesirable；
Coding is the most symmetrical: carry out symmetrical treatment the need of coded strings；
Fixing tooth mode: be divided into and not fixing, fixing single tooth, it is fixed as three kinds of modes of tooth of a certain scope；
Fixing tooth position and number: the coding that be there is a need to fix is set；
Step S13, according to described key code, the actual value that coupling is corresponding, call the key that the processing of described actual value is corresponding.
In this step, the key corresponding with the combination of this key parameter is produced according to the key code meeting default screening conditions, with meet default screening conditions key code as foundation, with the actual value that coupling is corresponding, in the coding generation of key, refers to the size of key tooth flower, it could also be possible that angle, by reading coding lookup corresponding tartar size value during saltation layer, with the corresponding key of this dimensioned.
In the embodiment of the present invention, default key code parameter is used to generate multiple combination, re-use the key code that the screening of default screening conditions generates, the last actual value corresponding according to the key code coupling after screening, during saltation layer, call the key that the processing of this value is corresponding.Owing to generating the combination of key parameter of key without h coding, therefore it is greatly saved the scramble time, and the repeated code that occurs when decreasing artificial treatment and few code phenomenon.
As a preferred embodiment, comprised the steps: before step S13
