In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.

Fig. 1 shows a method for screening barcode information according to the present invention, which can be applied to a terminal device (for example, a computer, in this embodiment, for convenience of understanding, the computer is used as a subject for explanation, but those skilled in the art will understand that the method can also be applied to other terminal devices as long as they can implement corresponding functions), and the method for screening barcode information includes the following steps:

s101, reading codes, namely placing the material tray at a specified position of the code reading area, automatically scanning and sequentially reading all bar code information on a label of the material tray to obtain decoding information corresponding to each bar code information.

Specifically, a label is attached to the tray, and bar code information representing various information exists on the label. For convenience of explanation, the screening method of the present embodiment will be described by taking bar codes as an example. However, it should be understood by those skilled in the art that the representation form of the barcode information of the present invention is not limited, and may be a two-dimensional barcode, a one-dimensional barcode, or the like.

In practical application, a code reader is externally connected to the computer and is controlled to automatically scan and read all bar code information on the material tray, so that decoding information corresponding to each bar code information is obtained.

S102, screening decoding information, and sequentially taking manufacturer information screening rules, product number rules, manufacturer number rules, date formats and quantity formats in a preset database as first screening rules to screen unique corresponding decoding information from the decoding information.

Optionally, the vendor information filtering rule includes: each character is a letter.

S102 includes: s112, using the manufacturer information screening rule as a first screening rule, screening out the decoding information of which each character is a letter and represents the manufacturer information.

Specifically, a plurality of manufacturer information are stored in the preset database, and the manufacturer information screening rule is the same as the decoding information and one of the manufacturer information, that is, the decoding information uniquely representing the manufacturer information is screened out. And in the screening process, matching each obtained decoding information with each manufacturer information in a preset database, and screening the decoding information representing the manufacturer information.

For example: the preset database stores 3 manufacturer information, namely AB, XY and NG; as shown in FIG. 2, the decoding information obtained after automatic code reading is 8, which are XX-XXXXXXX-XX (X represents any number from 0 to 9), 20000, A22360233BBC869502060, ABC0402D1D9EE000, AB, AAAAAAA + S0258, 20190506 and XYZ 233. And matching the obtained 8 pieces of decoding information with 3 pieces of manufacturer information in a preset database according to a manufacturer information screening rule, and screening AB as the decoding information representing the manufacturer information. Each manufacturer information has a manufacturer number rule and a product number rule corresponding to the manufacturer information, and after the decoding information representing the manufacturer information is screened out, the corresponding manufacturer number rule and the product number rule in the preset database can be called, and the decoding information representing the manufacturer number and the product number is screened out from the rest decoding information.

The number of manufacturer number rules corresponding to each manufacturer information may be multiple, and the decoding information representing the manufacturer number is considered to be screened out as long as any one of the manufacturer number rules is met. Similarly, there may be a plurality of product number rules corresponding to each preset manufacturer information, and the decoding information representing the product number is considered to be screened out as long as any one of the product number rules is met.

Optionally, the product numbering rule comprises: presetting the length of a product character and a preset position of a specific character; the vendor numbering rules include: presetting the character length of a manufacturer and presetting a character combination mode.

S102 further comprises: s122, screening decoding information representing the product number, of which the character length is the same as that of a preset product and the position of a specific character is the same as that of the preset position of the specific character, from each piece of un-screened decoding information by taking the product number rule as a first screening rule and combining the determined manufacturer information in S112;

s132 uses the manufacturer number rule as the first filtering rule, and combines the manufacturer information determined in S112 to filter out the decoding information representing the manufacturer number, whose character length is the same as the character length of the preset manufacturer and whose character combination manner is the same as the preset character combination manner, from the un-filtered decoding information.

Specifically, the specific character is determined according to the actual use condition, for example: "-", "+", "@", etc.; the position of the sensor is set according to the actual situation, for example: the 3 rd and 5 th characters are special characters, or the 4 th, 9 th and 13 th characters are special characters.

The preset product has different character lengths or different preset positions of specific characters, and a product numbering rule is formed.

For example: following the decoding information of the previous example, one product numbering rule corresponding to AB is: and presetting the product character length to be 12, and setting the 3 rd and 10 th characters as specific characters "-", and screening XX-XXXXXXX-XX from the rest 7 decoding information except for representing manufacturer information to be decoding information representing a product number.

Different manufacturers have specific rules to write their own manufacturer numbers, and can set their corresponding manufacturer number rules according to the manufacturers actually used. The preset character combination mode comprises the following steps: numbers, letters, and respective corresponding positions. Optionally, the preset character combination mode further includes: a specific character and its corresponding location.

Continuing with the example of the decoding information in the above example, the manufacturer character length is preset to be 16 in the manufacturer numbering rule corresponding to AB, and the preset character combination manner is as follows: the 1 st, 2 nd, 3 rd, 8 th, 10 th, 12 th and 13 th characters are letters, and the 4 th, 5 th, 6 th, 7 th, 9 th, 11 th, 14 th, 15 th and 16 th characters are numbers. The decoding information of ABC0402D1D9EE000 as the representative manufacturer number is screened out from the rest 7 bar code information except the representative manufacturer information.

The preset manufacturer number rules are used as a new manufacturer number rule when the preset manufacturer number characters have different lengths or different preset character combination modes.

It should be noted that when the decoding information representing the manufacturer number and the decoding information representing the product number are filtered, they are not in sequence, and because the rules of the two are different, no interference is generated.

Optionally, the date format comprises: a complete year, month, day format, a shorthand year, month, week format, and a year and week format; wherein, the characters in each format are numbers;

s102 further comprises: s142, using the date format as the first filtering rule, filtering out the decoded information (characters are numbers and conform to the complete year, month, day format, month, week format, or year, week format) representing the date from each of the decoded information that is not filtered out.

Specifically, after the decoding information representing the manufacturer information, the decoding information representing the product number, and the decoding information representing the manufacturer number are determined, the screening of the decoding information representing the date is started. The format of the date may be set in the format of the date.

Examples of full year, month and day formats are: 20190823, respectively; examples of shorthand year-on-day formats are: 190823, respectively; an example of a monthly week format is 1201, 12 for 12 months, 01 for week 1 of 12 months; an example of a week of year format is 1947, 19 for 2019 and 47 for week 47 of 19.

After the decoding information representing manufacturer information, manufacturer numbers and product numbers is screened out, after a part of interference is eliminated, the decoding information conforming to the date code format can be screened out from the rest decoding information more quickly. During screening, the characters are all numbers and conform to any format in a preset date code format.

Following the example of the decoded information in the above example, from the remaining five pieces of decoded information, it can be seen that characters are all numbers only 20000 and 20190506, and those conforming to the date format are only 20190506 which conforms to the full year, month and day format, and therefore 20190506 is screened as the decoded information representing the date code.

Optionally, the quantity format comprises: each character is a number;

s102 further comprises: s152 selects a decoding information (each character is a number) representing the number from each of the decoding information that is not selected, using the number format as the first filtering rule.

Specifically, the preset number format corresponding to the number is that each character is a number and has no other special characteristics, so that the characters are placed in the last digit for screening.

Following the example using the decoding information in the above example, after the decoding information representing the manufacturer information, the manufacturer number, the product number, and the date code is screened out, the remaining decoding information is not large, and the decoding information representing 20000 can be rapidly screened out.

In the embodiment, the information is sequentially screened according to the specific characteristics of each information, the manufacturer information with high uniqueness is used as a first screening target, so that the specific manufacturer numbers and product numbers of the subsequent manufacturer information are positioned, the dates and the number of the subsequent decoding information are sequentially screened out, the screening of the quick decoding information is realized, the accuracy is ensured, no human participation is needed in the screening process, and the operation efficiency of information registration during the storage of the material tray is greatly improved.

In practical use, when the material of the tray is not full, the information of the user of the tray needs to be printed, at this time, the date and the number may be four digits of pure numbers, and if the decoded information representing the date and the number cannot be accurately screened out only through the date format and the number format, therefore, another implementation mode is provided:

as shown in fig. 3, the method for screening barcode information includes:

s301, reading codes, namely placing the material tray at a specified position of the code reading area, automatically scanning and sequentially reading all bar code information on a label of the material tray to obtain decoding information corresponding to each bar code information;

s302, screening decoding information, namely screening out the unique decoding information corresponding to the representative manufacturer information which is the same as the preset manufacturer information from each decoding information by taking a preset manufacturer information screening rule, a product number rule, a manufacturer number rule, a date format and a quantity format in a preset database as first screening rules in sequence; if a plurality of decoding information are screened out simultaneously according to the first screening rule, all the screened-out decoding information are used as undetermined decoding information to be screened out again;

s303, screening the information to be decoded, and screening the information to be decoded again according to a second screening rule and by combining with the preset position relation of the bar code until the unique corresponding decoding information which accords with the first screening rule is screened from the information to be decoded; the second filtering rule is the next filtering rule of the first filtering rule.

Specifically, if a plurality of decoding information are simultaneously screened out according to the first screening rule, then the re-screening of all the screened-out plurality of decoding information as pending decoding information includes:

if the unique decoding information of the representative date which accords with the date format cannot be screened out for the first screening rule according to the date format, all the decoding information which accords with the date format is taken as undetermined decoding information;

the screening of the information to be decoded comprises the following steps:

and screening the decoding information representing the date and the decoding information representing the number from the decoding information to be determined by taking the number format as a second screening rule and simultaneously combining a preset first position relation between the number bar codes and the date bar codes, a preset second position relation of any other information except the date bar codes and the number bar codes, a scanning sequence during automatic scanning and the positions of the screened decoding information in all decoding information.

Generally, the setting position of each barcode information on the label has a rule corresponding to the setting position, that is, the preset first position relationship between the number barcode and the date barcode may be that the number barcode is before the date barcode, or the date barcode is before the number barcode, and is set according to the actual situation.

Considering that the label may be reversed, if the preset first positional relationship refers to the relationship between the label and the label when the label is being applied, as shown in fig. 5, and when the label is reversed, as shown in fig. 6, the positions of the respective information are reversed, which causes errors in the identification of the date code and the number.

Therefore, the positional relationship with other information is also added to confirm whether the current paste is the positive paste or the negative paste, thereby locating the positional relationship between the date code and the number.

In addition, the scanning order in the automatic scanning also affects the position determination between the respective pieces of information. For example: if the scanning order is from bottom to top, even if the label is pasted, the obtained decoding information is arranged on the first label, namely the last label. Therefore, when determining the position, the scanning order is also considered to ensure that the decoding information representing the date code and the number is correctly screened out.

As shown in fig. 4, the decoding information representing the number is 1850, the decoding information representing the date is 1908, both of which are 4-bit pure numbers, and the decoding information representing the date cannot be recognized accurately in conformity with the year-round format of the date format. Therefore, the screening is performed according to the preset first position relationship, the preset second position relationship and the scanning sequence.

The preset first position relationship is as follows: the number bar code is behind the date bar code when the time is right pasted; the preset second position relation is as follows: when the product is pasted, the product number is the first (or the manufacturer information is the second, etc.); the scanning sequence is from top to bottom and from left to right; the positions of all decoding information are arranged in sequence according to the scanning time; according to the product number, the current label is positioned to be a positive label, and 1850 is ahead of 1908, so that 1850 is screened out decoding information representing the number, 1908 is screened out decoding information representing the date code.

In this embodiment, the manner of screening the decoding information representing the manufacturer information, the product number and the manufacturer number is still the same as the manner of screening the decoding information representing the manufacturer information, the product number and the manufacturer number, and when the decoding information representing the number and the date cannot be accurately identified, information comprehensive judgment such as a position relationship, a scanning sequence and the like is introduced, so that the screening accuracy is improved.

Optionally, as shown in fig. 3, the method for screening barcode information further includes:

and S304, storing information, namely uploading each screened decoding information to a corresponding information column in the warehousing system for storage.

Specifically, the essence of screening out each information is to upload the information to a storage system for storage, so that the storage system is perfected, and the subsequent checking and maintenance of the material tray are facilitated. Each information that will screen out uploads to the storage system in the corresponding information column storage, can guarantee the correct save of information, and whole process need not artificial medium, has improved the operating efficiency greatly.

Optionally, the uploading the screened decoding information to a corresponding information column in the warehousing system for storage includes:

and uploading each decoding information to the corresponding information column in sequence for storage according to the position relation of the information columns corresponding to the manufacturer information, the product number, the manufacturer number, the date number and the quantity in the warehousing system.

Specifically, each information column in the warehousing system necessarily has a sequence, corresponding information can be sequentially uploaded according to the sequence, and the sequence is stored, so that the processing speed is increased.

For example: the sequence of the information columns in the warehousing system is manufacturer information, product numbers, manufacturer numbers, quantity and date codes in sequence, and the screened decoding information is uploaded and stored in sequence according to the sequence.

In the embodiment, the screened decoding information is automatically uploaded to a storage system for storage, manual intervention is not needed, and the operation efficiency is greatly improved.

It should be understood that, in the above embodiments, the size of the sequence number of each step does not mean the execution sequence, and the execution sequence of each step should be determined by functions and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

And matching the obtained 8 pieces of decoding information with 3 pieces of manufacturer information in a preset database according to a manufacturer information screening rule, and screening AB as the decoding information representing the manufacturer information.

Each manufacturer information has a manufacturer number rule and a product number rule corresponding to the manufacturer information, and after the decoding information representing the manufacturer information is screened out, the corresponding manufacturer number rule and the product number rule in the preset database can be called, and the decoding information representing the manufacturer number and the product number is screened out from the rest decoding information.

Optionally, the product numbering rule comprises: presetting the length of a product character and a preset position of a specific character; the screening module 82, screening out the decoding information of the representative product number that meets the product number rule from the unseparated decoding information, includes:

the screening module 82 screens out decoding information representing a product number, of which the character length is the same as the character length of a preset product and the position of a specific character is the same as the preset position of the specific character, from among the unset decoding information.

Optionally, the vendor numbering rules comprise: presetting manufacturer character length and a character combination mode;

the screening module 82, screening out decoding information of a representative manufacturer number that meets the manufacturer number rule from among the non-screened decoding information, includes:

the screening module 82 screens out decoding information representing manufacturer numbers, of which the character length is the same as that of a preset manufacturer and the character combination mode is the same as that of the preset character combination mode, from each piece of the non-screened decoding information.

Specifically, different manufacturers have their specific rules to write their own manufacturer numbers, and can set their corresponding manufacturer number rules according to the manufacturers actually used. The preset character combination mode comprises the following steps: numbers, letters, and respective corresponding positions. Optionally, the preset character combination mode further includes: a specific character and its corresponding location.

Optionally, the date format comprises: a complete year, month, day format, a shorthand year, month, week format, and a year and week format; wherein the characters in each format are numbers.

The screening module 82, which screens out the decoding information of the representative date in the format of the date code from each of the screened decoding information, includes:

the screening module 82 screens out the decoded information of the representative date, which has characters that are numbers and conforms to the complete year, month and day format, the abbreviated year, month and day format, the month and week format or the year and week format, from each piece of the decoded information that is not screened out.

Specifically, examples of the format of the whole year, month and day are: 20190823, respectively; examples of shorthand year-on-day formats are: 190823, respectively; an example of a monthly week format is 1201, 12 for 12 months, 01 for week 1 of 12 months; an example of a week of year format is 1947, 19 for 2019 and 47 for week 47 of 19.

After the decoding information representing manufacturer information, manufacturer numbers and product numbers is screened out, after a part of interference is eliminated, the decoding information conforming to the date format can be screened out from the rest decoding information more quickly. When screening, the characters are all numbers and conform to the format in any date format.

Following the example of the decoded information in the above example, from the remaining five pieces of decoded information, it can be seen that characters are all numbers only 20000 and 20190506, and those conforming to the format are only 20190506, which conforms to the full year, month and day format, and therefore 20190506 is screened as the decoded information representing the date code.

The number format corresponding to the number is that each character is a number without other special features, and therefore, the number format is put in the last digit for screening.

Optionally, the screening module 82, screening out the decoding information of the representative quantity conforming to the quantity format from each of the non-screened decoding information, includes:

the screening module 82 screens out the decoding information with the representative number of the numbers of the characters from the non-screened decoding information.

Following the example using the decoding information in the above example, after the decoding information representing the manufacturer information, the manufacturer number, the product number, and the date is screened, the remaining decoding information is not large, and the decoding information representing 20000 can be rapidly screened.

the screening module 82 is further configured to, when the unique decoding information of the representative date conforming to the date format cannot be screened out, take each piece of decoding information conforming to the date format as to-be-decoded information;

and screening the decoding information representing the date and the decoding information representing the quantity from the decoding information to be determined according to a preset first position relation between the quantity bar code and the date bar code, a preset second position relation of any other information except the date bar code and the quantity bar code, a scanning sequence during automatic scanning and the positions of the screened decoding information in all decoding information.

Specifically, generally, the setting position of each barcode information on the label has a rule corresponding to the setting position, that is, the preset first position relationship between the number barcode and the date barcode may be that the number barcode is before the date barcode, or that the date barcode is before the number barcode, and is set according to the actual situation.

Therefore, the positional relationship with other information is added to determine whether the current paste is the positive paste or the negative paste, thereby locating the positional relationship between the date and the number.

In addition, the scanning order in the automatic scanning also affects the position determination between the respective pieces of information. Therefore, when determining the position, the scanning order is also considered to ensure that the decoding information representing the date and the number is correctly screened out.

In this embodiment, the manner of screening the decoding information representing the manufacturer information, the product number, and the manufacturer number is still the same as the manner described above, and when the decoding information representing the number and date cannot be accurately identified, information comprehensive judgment such as a position relationship and a scanning order is introduced, so that the screening accuracy is improved.

Optionally, the screening device 8 of the barcode information is included in fig. 7, and the decoding information representing the manufacturer information, the decoding information representing the product number, the decoding information representing the manufacturer number, the decoding information representing the date, and the decoding information representing the number are screened out by the screening device of the barcode information;
