Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Flow chart shown in the drawings only illustrates, it is not necessary to including all content and operation/step, also not
It is that must be executed by described sequence.For example, some operation/steps can also decompose, combine or partially merge, therefore practical
The sequence of execution is possible to change according to the actual situation.
The invention discloses a kind of generation method of two dimensional code, the method is used for the anti-fake aspect of sealed package, this two
The generation method of dimension code can be applied in terminal or server, for prompting the opening number of packaging.
For example, the generation method of two dimensional code is applied to increase the function of anti-fake two-dimension code on drug packaging bottle, can recorde
The opening number of drug packaging bottle, prevents drug packaging bottle to be used again.It may naturally be used in other packagings, for example eat
Object bottle etc..In order to make it easy to understand, following embodiment will be described in detail by taking pharmaceutical packing bottle as an example.
With reference to the accompanying drawing, it elaborates to some embodiments of the application.In the absence of conflict, following
Feature in embodiment and embodiment can be combined with each other.
It please referring to shown in Fig. 1, Fig. 1 is a kind of schematic flow diagram of the generation method of two dimensional code of embodiments herein,
The generation method of the two dimensional code is used for drug packaging bottle.Wherein, the generation method of the two dimensional code includes step S101 to step
S105。
S101, the main ID of burning.
Wherein, the main ID may include the code name of grown place, model of drug of production etc., this number can be voluntarily
Setting, it is identical with the main ID of a batch of drug.
S102, multidigit random code is generated.
Wherein, random code is the 4-digit number generated at random according to algorithm or other long numbers.For example work as random code
When for 4-digit number, 4-digit number is respectively as follows: M1, M2, M3, M4.Above-mentioned algorithm can be as follows with self-setting, such as algorithm.
Algorithm 1:M1, M2=M1+8, M3=M1*2+M2, M4=M1+M2.
Algorithm 2:M1, M2=M1*M1, M3=M2+3, M4=M1+M2+2.
A number M1 is randomly generated, for example the number generated is 4, the number finally shown is 4***, it is assumed that random choosing
Algorithm 2 is selected, M2=16, M3=18, M4=22 are calculated according to formula.Lowest order is taken, then the number finally shown is 4682.More than
Only list the example of two algorithms.
S103, extra-code is generated according to the opening number of the sealed package.
Wherein, extra-code is to be generated according to the opening number of the sealed package, in the present embodiment sealed package
For pharmaceutical packing bottle, the bottle cap and bottle body of Packaging Bottle are opened, and extra-code generates immediately, thus extra-code show bottle cap and
Whether bottle body is opened.
S104, it generates including the main ID, the random code and the extra-code, generates URL link.
Wherein, the URL link of generation includes main ID, random code and extra-code, the URL's that triplicity ensures to generate every time
Uniqueness, URL is not only unique, and whether also show Packaging Bottle opened, it is specific it is opened several times.
S105, by the URL link of generation according to two dimensional code create-rule, generate two dimensional code.
Wherein, in order to facilitate user's operation, two dimensional code is converted by unique URL link of generation, (is moved for user
Terminal) scanning.
In some optional embodiments, extra-code is recorded by the way of cumulative, and the initial value of extra-code is 0, often
A Packaging Bottle is opened, extra-code adds 1.Specifically, when Key works Drug packing is completed, extra-code is 0, first switches on packet in user
After bottling, extra-code starts cumulative 1, and the value of extra-code is 1 at this time.After opening Packaging Bottle second of user, extra-code is again
Cumulative, the value of extra-code is 2 at this time, is successively added up by this method, after the 300th opening Packaging Bottle of user, extra-code at this time
Value be 300.The number of extra-code can also be as the effect for examining drug true and false.There are some reuse packets currently on the market
The case where dress, the genuine Packaging Bottle of pharmaceutical packing bottle, but the drug in Packaging Bottle just uses fake products, what the method generated
Two dimensional code can be generated according to the number that Packaging Bottle is opened, so that it may avoid the generation of such phenomenon.The number that Packaging Bottle is opened
It can also be used to estimate the validity period of Packaging Bottle internal product, drug is after packaging is opened, and validity period can greatly reduce, but user
It would generally forget the time of opening drug packaging bottle.Number of pass times can substantially estimate the time for opening Packaging Bottle, such as user
Drink medicine three times within one day, when the value of extra-code is 300 times, the time of substantially opening Packaging Bottle is 100 days, and server can be according to feelings
Condition prompts user, this drug is expired, prevents user from using expired drug.
Shown in referring to figure 2., in one alternate embodiment, in order to facilitate scanning input, in S105, by the generation
For URL link according to two dimensional code create-rule, generating after two dimensional code further includes S1051: by the two dimensional code be directed toward one it is presetting
Responder.
Presetting responder is the public small routine received, such as can select wechat little Cheng in China's Mainland
Sequence can also select Alipay small routine.Specific small routine does not limit specifically, is arranged according to practical situation.
It in one alternate embodiment, include the master in S104, described generate in order to be encrypted to the URL of generation
ID, the random code and the extra-code further include S1041, according to Encryption Algorithm, by the institute of generation after generating URL link
State URL link encryption.URL is encrypted in this approach, increases the safety of link.Specifically Encryption Algorithm can be selected voluntarily
It selects, it can also be other common Encryption Algorithm that Encryption Algorithm, which can be PRESENT algorithm,.
The second aspect of the present invention protects a kind of two-dimension code generator, which includes: inductor, controller
And display.In the opening and closing for carrying out induction sealing package, it connect inductor with controller, and inductor can will incude
The signal opened and closed to package is sent to controller, and controller generates two dimension using the generation method of above-mentioned two dimensional code
Code.Display is used to the two dimensional code that o controller generates, to check the true and false, the opening of packaging time of product for scanning input
Whether number and the product of packaging are expired.
