Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
With the continuous progress of science and technology, people can more and more easily acquire required information through an information carrier, wherein a bar code is an important novel information carrier. The bar code is a graphic identifier in which a plurality of black bars and white bars having different widths are arranged according to a certain encoding rule to express a set of information. Because of the different reflectivity of the black and white bars of a bar code, an identification device scans the bar code to obtain a set of data signals to read the information. Taking the sending of an article as an example, people initially convey information and the article by means of letters, however, only the telephone numbers and addresses of a sender and a receiver are described on an envelope, the real-time position of the letters cannot be tracked after the letters are sent out, and the sender and the receiver cannot know the specific transportation condition of the letters. Moreover, since no statistics are collected on the information of the letters during transportation, the letter loss is easy to occur. Therefore, in order to facilitate the user to grasp the situation of the item during transportation and reduce the loss rate of the item, a bar code is usually attached to a bill of the express delivery, and a transportation company scans the bar code to fill in detailed information of the express delivery, such as names, addresses, telephone numbers, types and weights of the sender and the receiver, and the like. In the process of commodity transportation, when a transfer point is reached, workers at the transfer point can scan the bar codes to update the position of the express delivery in real time, and a user can acquire real-time information of the commodity by scanning the bar codes on the express delivery bill. The goods are delivered by the courier after arriving at the area of the receiver, and when a user scans the bar codes to check the logistics information, the user can display the name, the telephone number and other information of the courier besides the position of the goods, so that the user can conveniently contact the courier to communicate with the problem of delivery of the express.
The conventional bar code has a large number of encoding bits, and occupies a large space when the bar code is printed. However, because some items have their own small volume, such as erasers, pencils, etc., the print width provided to the bar code is small, resulting in the black and white bars of the bar code coming together within a limited range of print widths. Fig. 1 is a schematic diagram illustrating comparison of barcode width printing provided in the embodiment of the present application. As shown in fig. 1, it is apparent that black and white bars of a bar code are clear when a normal width paper is used to print the bar code, and the black bars of the bar code overlap due to a reduction in the print width when a fixed width paper is used to print the bar code. When the bar code is identified by the identification equipment, the identification equipment cannot accurately identify the bar code due to the fact that the black bars and the white bars of the bar code are combined together, and the identification accuracy is low.
In view of the above problems, the present application provides a method for processing a barcode, which is used to solve the above problems. In the process of solving the problems, the inventor finds that the black bars and the white bars of the printed bar codes are combined together mainly because the number of coding bits is too large, so that the black bars and the white bars of the bar codes are overlapped in the printing process because of too large number. This problem can be solved by reducing the number of black and white bars of the bar code if the number of encoding bits can be reduced appropriately.
Based on the method, the data source to be coded is converted into the first hash character string, and other characters in the first hash character string are replaced by corresponding numbers according to the preset first corresponding relation between other characters and numbers, so that the second hash character string is obtained. And according to the length of the preset short code bar code, taking out a plurality of character groups corresponding to the length of the short code bar code from the second hash character string according to a preset interval, and generating the short code bar code according to the plurality of character groups. In limited printing width, black bars and white bars of the bar code can be clearly printed, and the problems that the bar code cannot be accurately identified by identification equipment and the identification precision is low are effectively solved.
For example, the barcode processing method provided in the embodiment of the present application may be applied to an application scenario diagram shown in fig. 2. Fig. 2 is a schematic view of an application scenario of the barcode processing method according to the embodiment of the present application. As shown in fig. 2, the schematic diagram may include: electronic device 10, identification device 11. The number of the identification devices 11 is at least one, and three are taken as an example here, and are respectively the identification device 111, the identification device 112, and the identification device 113.
The electronic device 10 is capable of converting the data source code to a short code and generating the short code into a short code barcode. In addition, the electronic device 10 can also store the mapping relationship between the short codes and the data source in a short code database, and count the use states of the short codes.
When the identification device 11 identifies the short code barcode, the electronic device 10 can also receive the short code sent by the identification device 11, obtain a data source corresponding to the short code according to a mapping relationship between the short code and the data source, execute a logic corresponding to the data source, and return an execution result to the identification device 11.
It is understood that the electronic device 10 may be a terminal device, such as a computer, a tablet computer, etc., or a server, such as a barcode processing platform, etc. Therefore, the present embodiment is explained by referring to the terminal device and the server collectively as the electronic device, and the electronic device may be specifically the terminal device, and may also be the server, which may be determined in actual situations.
The code reading device 11 is mainly configured to scan a short code barcode to obtain the short code, send a barcode identification request to the electronic device 10 according to the short code, and receive an execution result returned by the electronic device 10.
Optionally, the schematic diagram may further include: the printing device 12.
The printing device 12 is mainly configured to receive a print request sent by the electronic device 10, acquire a short barcode to be printed and a print position, and print the short barcode at a specified print position.
The technical solution of the present application will be described in detail below with reference to specific examples.
It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 3 is a schematic flowchart of a first embodiment of a barcode processing method according to an embodiment of the present application. As shown in fig. 3, the barcode processing method may include the following steps:
s101, converting a data source to be coded into a first hash character string.
In the embodiment of the application, because the number of the character bits of the data source is large, if the data source is directly converted into the bar code, the bar code is not clearly printed, and the white bar and the black bar are overlapped. The electronic device needs to acquire the data source and process it to convert it into short codes. The mapping relation is established between the short code and the data source, and all information of the data source can be acquired through the short code.
Specifically, the short code is mainly composed of numbers, capital and lower-case English letters and special symbols in a short code character set. Wherein, the number, capital and lower case English letters and the number of special symbols in the short code character set can be freely set. In the embodiment of the present application, a short code character set composed of 64 characters, including numbers 0 to 9, upper and lower case english letters, and 2 arbitrary special symbols, is taken as an example for explanation.
In this step, the electronic device needs to acquire a data source to be encoded, the data source has a certain logical relationship with the article or the information that the data source refers to, and all data information of the article or the information can be viewed through the data source. For example, if the data source represents logistics information of an article, real-time location information of the article and a call of a dispatcher can be checked through the data source according to a logical relationship between the data source and the logistics information.
The data source may be a character string generated according to a certain rule, or may be a character and a link, for example, JDV000165020743-1-1,% # +, http:// www.example.com, and the like.
Because the character composition of the data source is complex, the data source may contain numbers, upper and lower case letters and symbols at the same time, if the data source is directly related to the short code database to construct a corresponding logical relationship, the corresponding relationship system is huge, and the conversion efficiency is affected. There is therefore a need for converting data sources so that the data sources can be more efficiently converted to short codes.
Specifically, after acquiring a data source to be encoded, the electronic device converts the data source to form a first hash character string. For example, the data source may be converted into a cryptographic hash function, such as MD5, MD6, MD7, etc., to generate a first hash string of a fixed length, such as 16 bits, 32 bits, etc., which is not limited in this application.
Optionally, the first hash string includes numbers and other characters, where the other characters may be upper and lower case letters, or may be special symbols, which is not limited in this application.
S102, replacing other characters in the first hash character string with corresponding numbers according to a preset first corresponding relation between other characters and numbers to obtain a second hash character string.
In this step, since the first hash string includes numbers and other characters, the other characters in the first hash string are further processed to be converted into the second hash string, so as to reduce the complexity of converting the second hash string into a short code. Wherein all characters in the second hash string are numbers.
Specifically, the electronic device needs to preset a first correspondence between letters and numbers, and convert the letters in the first hash string into numbers. Optionally, upper and lower case letters may correspond to the same number, or may correspond to different numbers, and the embodiment of the present application is not particularly limited. For example, the upper and lower case letters may correspond to the same number, and the letter a or letter a may correspond to the number 1, B or B may correspond to the number 2, C or C may correspond to the number 3, …, and the letter Z or letter Z may correspond to the number 26.
Specifically, the letters in the first hash string are converted to numbers by a first correspondence between other characters and numbers. If the first hash string contains a symbol, the symbol is skipped and deleted directly during the conversion process.
S103, according to the length of the preset short code bar code, a plurality of character groups corresponding to the length of the short code bar code are taken out from the second hash character string according to the preset interval.
Considering that the short bar code has a small number of bits, if the number of the articles or the information is large, the short bar code may not be sufficient. The short code bar code is generally 4 bits, 5 bits or 6 bits, the length of the short code bar code is not specifically limited in the embodiment of the application, and the short code bar code can be determined according to actual requirements
Illustratively, the number of short codes respectively existing when the short code bar code length is 4 bits, 5 bits and 6 bits when the short code character set contains 64 characters is calculated.
Fig. 4 is a schematic view of a calculation interface for calculating the number of short codes when the number of bar code bits of the short codes is 4 bits according to an embodiment of the present application. Fig. 5 is a schematic view of a calculation interface for calculating the number of short codes when the number of short code bar codes is 5 bits according to an embodiment of the present application. Fig. 6 is a schematic view of a calculation interface for calculating the number of short codes when the number of short code bar codes is 6 bits according to an embodiment of the present application. As shown in fig. 4, N is the number of characters included in the short code character set, and 64 characters are total; and M is the number of the short code bar code and is 4 bits. Using equation (1): k ═ n + m-1! /[ (n-1)! M! And calculating the number of the short codes, wherein K is the number of the short codes, and n, m and N, M are consistent in reference, and are the number of characters contained in the short code character set and the number of short code bar codes respectively. As can be seen from the calculation, when the short code word set includes 64 words, a total of 766480 short codes are available to the user when the number of short code bits is set to 4 bits.
As shown in fig. 5 and 6, in accordance with the process of calculating the number of short codes when the number of short code bar codes is 4 bits, it can be found by calculation that when the short code character set includes 64 characters, a total of 10424128 short codes are available to the user when the number of short code bar codes is 5 bits; when the number of bits of the short code bar code is set to 6 bits, 119877472 short codes are available for the user.
In this step, a suitable character group is selected from the second hash character string according to the length of the short code barcode. The number of bits of the short code bar code can be selected according to the calculation results of the number of the short codes in fig. 4, 5 and 6 in combination with the number of the data sources. For example, if there are 846257 data sources in total, since the number of short bar codes with 4 digits is less than that of the data sources, the data sources cannot be converted into short bar codes with 4 digits and cannot be converted into short bar codes with 5 or 6 digits.
Specifically, after the length of the short code barcode is selected, a preset interval needs to be set, and the electronic device takes out a plurality of character groups from the second hash character string according to the preset interval. The preset interval may be a fixed interval or a non-fixed interval, for example, 1, 2, 3, or the like, or 1 every first time, 2 every second time, 3 every third time, or the like, and the application does not specifically limit this.
Optionally, the number of bits of the character set may be freely set, such as 2 bits, 3 bits, and the like, which is not specifically limited in this application.
Specifically, the number of the selected character sets is determined according to the number of the short code bar codes, and when the number of the selected character sets is consistent with the number of the short code bar codes, the character sets are stopped being selected.
Optionally, the electronic device may select from the first character of the second hash string, or may start selecting at a certain position in the string, which is not specifically limited in this application.
And S104, generating the short code bar code according to the plurality of character groups.
In this step, the character group is converted into short code characters and short codes are formed according to a certain sequence to generate short code bar codes.
In a specific embodiment, since conversion is required according to the relationship between the character group and the short code, a second corresponding relationship between the character group and the short code can be established. Wherein each burst corresponds to a short code. Converting each acquired character group into a short code character according to a second corresponding relation, illustratively, 64 characters are in a short code character set, and when the character group is 24, converting the character group into W according to the second corresponding relation between the character group and the short code; when the character group is 76, F is converted according to the second correspondence between the character group and the short code.
In another specific embodiment, the short code characters may also be numbered in a certain order. Illustratively, 64 characters in the short code character set are numbered from 1 to 64, respectively, and each character corresponds to a unique number. And taking the selected character group of each group as the serial number of the short code character, and converting the short code character into the short code character according to the corresponding relation between the short code character and the serial number. When the numerical value of the character group is smaller than that of the short code character, directly converting the numerical value of the character group and the numerical value of the short code character correspondingly; when the value of the character group is greater than the value of the short code character, the total number of the short code character set is subtracted from the value of the character group, and the difference value is used as the number of the short code character to perform corresponding conversion with the short code character. Illustratively, the short code character set has 64 characters, and when the character set is 24, the short code character set is converted into a letter W according to the corresponding relationship between the short code character and the serial number; when the character group is 76, since the total number of the numerical values in the short code character set is exceeded, it is necessary to first subtract 64 from 76 to obtain a difference value of 12, and convert 12 as the number of the short code character into a letter F according to the correspondence between the short code character and the number.
Specifically, the converted characters are extracted and arranged according to a certain sequence, for example, from left to right, and the like, which is not limited by the present solution.
Specifically, after the short code is generated, the mapping relationship between the short code and the corresponding data source and the generation time of the short code are stored in the short code database, and the state of the short code is changed into the use state. The short code database comprises a data source, corresponding short codes, a use state and generation time information. The using state is divided into a using state and a recycling state, after the short code is used for a period of time, the corresponding commodity or information can be considered to be used or transmitted, in order to avoid the waste of the short code, the short code can be recycled for secondary utilization, and the state of the short code database is changed from the using state to the recycling state. Illustratively, table 1 is a short code database master table field.

In the process of generating the short code, due to the reason of preset intervals and selected positions, the situation that different data sources generate the same short code may exist, so that collision processing needs to be performed on the short code, the electronic equipment checks the state of the short code in the short code database after generating the short code, and if the state of the short code is a recovery state, which indicates that the short code can be used, the use state in the database is changed into a use state; if the short code is in use state, a new short code needs to be regenerated.
Specifically, the regeneration of the short code may be performed by modifying the preset interval and/or modifying the start position of the selected character set. For example, if the preset interval of the first generated short code is 2 characters, the preset interval may be modified into 2 characters; if the character group is selected from the first character of the second hash character string during the first generation of the short code barcode, the selection may be modified to be performed from the seventh character of the second hash character string, or the preset interval and the selection position may be modified at the same time.
Specifically, each short code character corresponds to a black bar or a white bar with different reflectivity, the corresponding black bar or the corresponding white bar is generated according to the short code character in the short code, and the short code bar codes are generated by combination.
