The present application will be described in further detail with reference to the following drawings and specific embodiments.

The word "exemplary" is used hereinafter to mean "serving as an example, embodiment, or illustration. Any embodiment described as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

With the frequent occurrence of epidemic situations, the universal nucleic acid detection for the majority of people has become more and more important. Medical personnel can adopt the test tube attached with the bar code when carrying out nucleic acid detection on personnel who receive nucleic acid detection, and through reading the content of bar code, just can acquire the serial number information of the personnel who carry out nucleic acid detection very conveniently, and then according to personnel's serial number information, inform relevant personnel with nucleic acid detection's testing result. In the process of collecting the nucleic acid information of personnel through the test tube or detecting the nucleic acid information, the bar code is easily polluted, and the conditions can cause that the read bar code is wrong or incomplete. In the process of reading the bar code, the bar code is blocked, and the finally read bar code is wrong or incomplete. If the read bar code is wrong or incomplete, the relevant person corresponding to the detection result cannot be determined, and the relevant person cannot be notified. Therefore, the bar code needs to be verified, and it is important to prevent the detection result from being unable to be notified to the corresponding relevant personnel due to errors or incompleteness of the read bar code.

In order to prevent a detection result from being unable to be notified to corresponding related personnel due to errors or incompleteness of a read bar code, and improve the accuracy and the integrity of reading the bar code, the application provides a bar code checking method, which can respectively obtain a data bit parameter and a checking parameter in a bar code picture, check bar code information in the bar code picture based on the obtained data bit parameter and the checking parameter, and when the checking result is that the checking is passed, can output the content of the bar code, and when the checking result is that the checking is not passed, output prompt information of a bar code reading error so as to prompt medical personnel that the read bar code has errors.

The embodiment of the application provides a bar code checking method, as shown in fig. 1, comprising the following steps:

step S101, respectively obtaining data bit parameters and verification parameters in the bar code picture.

In some embodiments, the data bit parameter may be the content of a data bit in the barcode information, or may be the number of data bits in the barcode information. The data bit content may include numbers, letters, characters, and the like. The verification parameter may be a check digit value in the bar code information. The barcode information may be obtained by recognizing a barcode in a barcode picture, or may be obtained by recognizing data information in a barcode picture by OCR. That is, the check bit value may be set according to the number of data bits in the barcode information, or may be set according to the data bit content of each data bit.

In other embodiments, the barcode picture may include a barcode and data information, the data bit content in the barcode may be obtained by reading the barcode, and the data information in the barcode picture is identified by OCR, so as to obtain the data bit content in the data information. The data bit parameter may be the data bit content in the barcode and the verification parameter may be the data bit content in the data information.

In other embodiments, the barcode information in the barcode picture may be acquired multiple times. The data bit parameter is the data bit content of the target bar code information in the bar code information acquired for multiple times, and the target bar code information is the bar code information acquired at any time. The verification parameters are data bit contents of other bar code information except the target bar code information in the bar code information acquired for multiple times. For example, the barcode information in the barcode picture may be acquired three times, the barcode information acquired at any one time in the barcode information acquired three times is taken as the target barcode information, and the data bit parameter is the data bit content of the target barcode information; the other two times of acquired bar code information are other bar code information, and the verification parameter is the data bit content of the other bar code information.

And S102, verifying the bar code information in the bar code picture based on the data bit parameters and the verification parameters.

In some embodiments, the data bit parameter may be directly compared with the verification parameter, and if the data bit parameter is consistent with the verification parameter, the verification result is determined to be a verification pass; and if the data bit parameter is not consistent with the verification parameter, determining that the verification result is verification failure.

Specifically, when the data bit parameter and the verification parameter meet any one of the following three setting conditions, the data bit parameter and the verification parameter may be directly compared: the first setting condition is: the data bit parameter is the number of data bits in the bar code information, and the check parameter is a check bit value in the bar code information; the second setting condition is: the data bit parameter is the data bit content in the bar code picture, and the check parameter is the data bit content in the data information in the bar code picture; the third setting condition is: the data bit parameter is the data bit content of the target bar code information in the bar code information acquired for multiple times, and the check parameter is the data bit content of other bar code information except the target bar code information in the bar code information acquired for multiple times, wherein the target bar code information is the bar code information acquired at any time.

In other embodiments, the number to be verified can be determined according to the data bit parameter, and if the number to be verified and the verification parameter meet the preset condition, the verification result is determined to be verification pass; and if the number to be verified and the verification parameters do not accord with the preset conditions, determining that the verification result is verification failure. The preset condition may be that the number to be verified is consistent with the verification parameter, or that the number to be verified is in a multiple relationship with the verification parameter, for example, the number to be verified may be 2 times of the verification parameter. The preset condition may also be that a difference between the number to be checked and the checking parameter satisfies a set threshold, for example, the difference between the number to be checked and the checking parameter may be 2.

Specifically, the data bit parameter may be the data bit content in the barcode information, and the check parameter may be a check bit value in the barcode information. The data bit value corresponding to the barcode information can be determined according to the data bit content in the barcode information, then the data bit value is summed to obtain a data sum, and the data sum can be directly used as a number to be checked corresponding to the barcode information, or the data sum and a set value are subjected to modulo operation to obtain the data sum and a corresponding remainder, and then the remainder is used as the number to be checked corresponding to the barcode information. When the number to be verified and the check digit value are not in accordance with the preset condition, the check result can be determined as that the check is passed.

And step S103, if the verification result is that the verification fails, outputting prompt information of bar code reading errors.

When the verification result of the verification of the barcode information in the barcode picture is that the verification fails, the read barcode information can be determined to be wrong and unreliable, and prompt information of the barcode reading error can be output.

In an embodiment, when the verification result of the verification of the barcode information in the barcode picture is that the verification is passed, it can be determined that the read barcode information is correct and reliable, and the read barcode content can be output.

Specifically, in some embodiments, only the barcode may be included in the barcode picture, check bits may be set in the barcode, and other bits except the check bits are used as data bits, that is, the barcode may include data bits and check bits. The data bits and the check bits in the barcode may be any number of bits, and the check bits may be set at any position of the barcode, for example, the check bits may be set at the end or the middle of the barcode. And reading the bar code in the bar code picture to acquire the bar code information. The bar code information comprises data bit content and check bit values, wherein the data bit content is the content on the data bits of the bar code, and the check bit values are the numbers on the check bits of the bar code.

For example, fig. 2 is a barcode picture, and the barcode picture only includes a barcode composed of black and white rectangles, when the barcode in fig. 2 is read by a barcode scanning device, barcode content "978435698" shown in fig. 3 can be obtained, where "97843569" is data bit content, and "8" is check bit value.

The data bit content in the barcode may be used as the data bit parameter, and the check bit value in the barcode may be used as the check parameter. Or the number of data bits in the bar code may be used as a data bit parameter, and the check bit value in the bar code may be used as a check parameter.

In other embodiments, the barcode picture may include data information in addition to the barcode, and both the barcode and the data information only include data bits, and the barcode in the barcode picture may be read, the data bit content in the barcode is obtained, and the data information in the barcode picture is identified by using an OCR (Optical Character Recognition) method, so as to obtain the data bit content in the data information. For example, fig. 4 is a barcode picture, where a barcode is formed by black and white rectangles, and "SVSQPO 2080" is data information, and the barcode in fig. 4 is read by a barcode scanning device, so as to obtain the data bit content "SVSOPO 2080" shown in fig. 5, and the data information in fig. 4 is identified by OCR, so as to obtain the data bit content "SVSQPO 2080" shown in fig. 6. The data bit content in the barcode may be used as the data bit parameter and the data bit content in the data information may be used as the verification parameter.

The OCR technology is a character recognition technology that converts characters into an image file of black and white dot matrix optically and converts characters in the image file into a text format. The whole picture can be traversed through a sliding window algorithm, supervised marked training sample characteristics are judged, after a target picture with a target character area is found, the target picture can be rectangularly extracted, then one-dimensional sliding window movement is carried out in a rectangle, the space between characters is judged, the characters are divided, the process that the character area is rectangularly divided and is divided into different characters is finished, then the divided characters can be predicted according to the supervision algorithm, character classification is obtained, each character in the target character area can be recognized, and finally subsequent processing and correction can be carried out on the recognized characters.

In other embodiments, the barcode and the data information in the barcode picture also both include only data bits, and the barcode or the data information in the barcode picture can be read multiple times to obtain the data bit content of the barcode or the data information. The data bit content of the target barcode or data information in the barcode or data information acquired multiple times can be used as the data bit parameter, and the data bit content of other barcodes or data information except the target barcode or data information in the barcode or data information acquired multiple times can be used as the verification parameter. The target bar code or data information may be bar code or data information read at any time.

In an embodiment, the barcode picture may include both the barcode and the data information, the barcode in the barcode picture may be identified by using an infrared scanning device to obtain a data bit parameter and a verification parameter corresponding to the barcode, and if a verification result of verifying the barcode information according to the data bit parameter and the verification parameter corresponding to the barcode is a verification pass, the barcode information obtained according to the identified barcode may be directly output. And if the verification result of verifying the bar code information according to the data bit parameters and the verification parameters corresponding to the bar codes is that the verification fails, the bar code information obtained according to the identification bar codes is wrong. For example, the bar code may be damaged, contaminated, or obscured, which may cause errors in the bar code information obtained by identifying the bar code.

If the barcode information obtained by identifying the barcode is wrong, the data information in the barcode picture can be identified by using an OCR technology, the data bit parameter and the verification parameter corresponding to the data information are obtained, the barcode information is further obtained, and the barcode information is verified according to the obtained data bit parameter and the verification parameter, so that the correct barcode information is obtained.

Compared with the prior art, when the bar code in the bar code picture is polluted or shielded to cause the read bar code to be wrong or incomplete, the method for manually inputting the bar code information can obviously improve the efficiency of obtaining the bar code information, can avoid the problem that the obtained bar code information is incorrect due to the input error when the bar code information is manually input, and ensures that the correct bar code information is obtained.

The bar codes in the embodiment of the application can come from different mechanisms and regions, so that the verification method for verifying the bar codes and the setting of the positions and the lengths of the verification bits in the bar codes can be different. Specifically, different verification methods for verifying the barcode may be embodied in different manners of calculating a data bit value in the barcode information. The different settings of the positions and the lengths of the check bits in the bar code can be embodied according to different mechanisms or regions, the check bits can be set at different positions of the bar code, and the check bits with different lengths can also be set in the bar code, so that the compatibility of checking the bar code is improved. For example, for different hospitals a and B, hospital a may set the check digit in the middle of the barcode and set with 4 check digits, while hospital B may set the check digit at the end of the barcode and set with 2 check digits.

In some embodiments, the data bit parameter may be a data bit content in the barcode information, and the check parameter may be a check bit value in the barcode information, where the data bit content and the check bit value may both be obtained by identifying a barcode in a barcode picture, and may also both be obtained by identifying data information in a barcode picture by OCR.

After the data bit content and the check bit value in the bar code information are determined, the number to be checked corresponding to the bar code information can be determined according to the data bit content, the number to be checked and the check bit value are compared, and when the number to be checked and the check bit value are consistent, the check result can be determined to be a check pass, so that the read bar code information is correct and credible. When the number to be checked is inconsistent with the check digit value, it can be determined that the check result is a check failure, which indicates that the read barcode information is wrong and unreliable.

The number to be checked can be determined according to the content of the data bits. Specifically, after the data bit content in the barcode information is obtained, the data bit value corresponding to the barcode information may be determined according to the data bit content, a data sum may be obtained by summing the data bit values, and the number to be checked corresponding to the barcode information may be determined according to the obtained data sum. For example, the data sum may be used as the number to be checked corresponding to the barcode information, or the data sum may be modulo-operated with a set numerical value to obtain the data sum and a corresponding remainder, and the remainder is used as the number to be checked corresponding to the barcode information.

In an embodiment, after the data bit value corresponding to the barcode information is determined according to the data bit content in the barcode information, the data bit value may be summed to obtain a data sum, and the data sum obtained by summing is directly used as the number to be checked corresponding to the barcode information and compared with the check bit value in the barcode information to determine the check result.

For example, identifying the barcode in FIG. 4 results in the data bit content "SVSQPO 2" and check bit value "540" in FIG. 7. After obtaining the data bit content "SVSQPO 2", the data bit value corresponding to each data bit content can be determined according to an ASCII (American Standard Code for Information Interchange) Code table, that is, the values corresponding to the data bit contents "S", "V", "S", "Q", "P", "O", and "2" are respectively searched in the ASCII Code table, and the value corresponding to "S" is "83", "the value corresponding to V" is "86", "the value corresponding to S" is "83", "the value corresponding to Q" is "81", "the value corresponding to P" is "80", "the value corresponding to O" is "79", and the value corresponding to 2 "is" 50 "can be obtained. And sequentially adding the determined data bit values to obtain data sum '542', directly taking the data sum '542' as a number to be verified, and comparing the data sum '542' with the check bit value '540', so that the verification result can be determined to be that the verification fails.

In another embodiment, after the data sum is obtained by summing the data bit values, the data sum and a set value may be subjected to a modulo operation to obtain the data sum corresponding to a remainder, and the remainder is used as a number to be checked corresponding to the barcode information and compared with the check bit value in the barcode information to determine a check result. For example, identifying the barcode in fig. 4 can result in the data bit content "SVSQPO 208" and the check bit value "4" in fig. 8. After the data bit content "SVSQPO 208" is obtained, the data bit value corresponding to each data bit content can be determined according to the ASCII code table, that is, the value corresponding to "S" is "83", "V" is "86", "S" is "83", "Q" is "81", "P" is "80", "O" is "79", "2" is "50", "0" is "48", and "8" is "56", respectively. And sequentially summing the determined digit values of the data to obtain a data sum 646, and performing modular operation on the data sum 646 and a set numerical value 6 to obtain a remainder of the data sum 646 of 4. And comparing the remainder 4 serving as the number to be checked with the check digit value of 4 to determine that the check result is a check pass.

In the above step, when the data bit values corresponding to the barcode information are summed, the data sum corresponding to the data bit values can be obtained through different operation modes. For example, some or all data bit values in the barcode information may be directly summed to obtain a data sum; or, multiplying part or all of the data bit values in the bar code information by the corresponding preset coefficients to obtain weighted data bit values corresponding to the data bit values, and then summing the weighted data bit values to obtain the data sum.

Specifically, the first operation method: the data sum can be obtained by directly summing the numerical values of the data bits in the bar code information.

The second operation method: each data bit value corresponding to the barcode information may be multiplied by a corresponding preset coefficient to obtain a weighted data bit value corresponding to each data bit value, and then the weighted data bit values are summed to obtain a data sum. For example, the data bit values determined according to the data bit contents are respectively "9", "7", "8", "4", "3", "5" and "6", and the preset coefficient corresponding to "9" is 1, the preset coefficient corresponding to "7" is 1, the preset coefficient corresponding to "8" is 1, the preset coefficient corresponding to "4" is 2, the preset coefficient corresponding to "3" is 2, the preset coefficient corresponding to "5" is 2, and the preset coefficient corresponding to "6" is 1. Multiplying each data bit value by the corresponding preset coefficient respectively to obtain a weighted data bit value corresponding to 9 as 9, a weighted data bit value corresponding to 7 as 7, a weighted data bit value corresponding to 8 as 8, a weighted data bit value corresponding to 4 as 8, a weighted data bit value corresponding to 3 as 6, a weighted data bit value corresponding to 5 as 10 and a weighted data bit value corresponding to 6 as 6 in turn. The weighted data bit values "9", "7", "8", "8", "6", "10" and "6" are added in sequence to obtain the data sum "54".

The third operation mode is as follows: the data bit values of the set number can be selected from the data bit values corresponding to the bar code information, and the selected data bit values of the set number are added to obtain the data sum. For example, the data bit values determined according to the data bit contents are respectively "9", "7", "8", "4", "3", "5", "6", 3 data bit values of "8", "4" and "6" can be selected from the data bit values, and the data sum "18" can be obtained by sequentially adding "8", "4" and "6".

The fourth operation mode: after the data bit values of the set number are selected, each data bit value in the selected data bit values can be multiplied by the corresponding preset coefficient to obtain weighted data bit values of the set number, and then the weighted data bit values of the set number are summed to obtain data sum. For example, the data bit values selected from the data bit values "9", "7", "8", "4", "3", "5" and "6" are "8", "4" and "6", the data bit value "8" may be multiplied by the preset coefficient "2", "4" may be multiplied by the preset coefficient "3", and "6" may be multiplied by the preset coefficient "1", the weighted data bit value "16" corresponding to "8", the weighted data bit value "12" corresponding to "4", the weighted data bit value "6" corresponding to "6" may be obtained, and then "16", "12" and "6" may be sequentially added to obtain the data sum "34".

The sum of the data corresponding to the data bit value is obtained through different operation modes, and then the number to be checked is obtained, so that the checking accuracy of checking the bar code can be improved.

In other embodiments, the data bit parameter may be the content of a data bit in a barcode within a barcode picture and the verification parameter may be the content of a data bit in data information within a barcode picture. The data bit content obtained by identifying the bar code can be compared with the data bit content obtained by identifying the data information, and when the data bit content corresponding to the bar code is consistent with the data bit content corresponding to the data information, the verification result can be determined to be verification passing, which indicates that the read bar code information is correct and credible. When the data bit content corresponding to the barcode is inconsistent with the data bit content corresponding to the data information, it can be determined that the verification result is verification failed, indicating that the read barcode information is wrong and unreliable. For example, by identifying the barcode in fig. 4, the data bit content "SVSOPO 2080" in fig. 5 can be obtained, by identifying the data information in fig. 4, the data bit content "SVSQPO 2080" in fig. 6 can be obtained, by comparing "SVSOPO 2080" with "SVSQPO 2080", since "SVSQPO 2080" is not consistent with "SVSOPO 2080", it can be determined that the check result of checking the barcode information is a check failure, and it is also indicated that the barcode is read with an error.

In other embodiments, the barcode within the barcode image may be read multiple times to obtain the data bit content in the barcode information. The data bit content of the target barcode information in the barcode information acquired multiple times can be used as the data bit parameter, the data bit content of other barcode information except the target barcode information in the barcode information acquired multiple times can be used as the verification parameter, and the target barcode information is the barcode information acquired at any time. The data bit content in the target bar code information and the data bit content in other bar code information can be respectively compared, and when the data bit content in the target bar code information is consistent with the data bit content in other bar code information, the verification result can be determined to be verification passing, and the read bar code information is correct and credible. When the data bit content in at least one piece of other bar code information is inconsistent with the data bit content in the target bar code information, the verification result can be determined to be verification failure, and the read bar code information is wrong and unreliable.

For example, the barcode in fig. 4 is read three times, the data bit content obtained by the first reading may be used as the data bit content in the target barcode information, and the data bit content obtained by the second and third reading may be used as the data bit content in other barcode information. When the data bit contents obtained by three times of reading are all 'SVSQPO 2080', namely the data bit contents obtained by each time of reading are consistent, the verification result can be determined to be verification pass, the barcode reading is correct, and the barcode content is 'SVSQPO 2080'. When the content of the data bit obtained by the first reading is 'SVSQPO 2080', the content of the data bit obtained by the second reading is 'SVSQPO 2080' and the content of the data bit obtained by the third reading is 'SVSOPO 2080', the content of the data bit obtained by the first reading is inconsistent with the content of the data bit obtained by the third reading, so that the verification result can be determined as that the verification fails and the barcode reading is incorrect.

In other embodiments, the data bit parameter may also be the number of data bits in the barcode information, and the check parameter may be a check bit value in the barcode information, where the number of data bits is compared with the check bit value, and when the number of data bits is consistent with the check bit value, it may be determined that the check result is a check pass and the barcode is correctly read. When the number of the data bits is inconsistent with the number of the check bits, the check result can be determined as that the check fails, the reading of the bar code is wrong, and prompt information of the bar code reading error is output. For example, if the content of the data bits in fig. 3 is "97843569" and the check bit value is "8", the number of the data bits in fig. 3 is "8", and the number of the data bits "8" is compared with the check bit value "8", so that it can be determined that the check result is that the check is passed and the barcode is correctly read.

As shown in fig. 9, the barcode checking method proposed in the present application is described in detail by a specific embodiment as follows:

step S901, a data bit content and a check bit value in the barcode are obtained.

And identifying the bar code to obtain the data bit content and the check bit value in the bar code.

Step S902, determining a data bit value according to the data bit content.

The numerical value corresponding to the content of each data bit can be sequentially searched in an ASCII code table, and the numerical value of the data bit is determined according to the numerical value corresponding to the content of each data bit.

Step S903, summing the data bit values to obtain a data sum.

The data bit values may be summed to obtain a data sum by any one of the following:

the first way is to sum the individual data bit values to obtain a data sum.

The second way is to multiply each data bit value by the corresponding preset coefficient to obtain the weighted data bit value corresponding to each data bit value, and then sum up each weighted data bit value to obtain the data sum.

The third method is to select a set number of data bit values from the data bit values and sum the set number of data bit values to obtain a data sum.

The fourth method is to select a set number of data bit values from the data bit values, multiply each data bit value of the set number of data bit values by a corresponding preset coefficient to obtain a set number of weighted data bit values, and sum the set number of weighted data bit values to obtain a data sum.

And step S904, determining the number to be checked corresponding to the bar code according to the data sum.

After the data sum is obtained, the data sum can be directly used as the number to be checked corresponding to the bar code, or the data sum and a set numerical value are subjected to modular operation to obtain the data sum corresponding to the remainder, and then the remainder is used as the number to be checked corresponding to the bar code.

Step S905, determining a checking result according to the number to be checked and the check digit value.

Step S906, determining whether the checking result is that the checking is passed; if not, go to step S907; if so, step S908 is performed.

In step S907, the barcode is read incorrectly, and prompt information of the barcode reading error is output.

Step S908, the barcode is read correctly, and the content of the barcode is output.

When the number to be verified and the check digit number do not accord with the preset condition, the verification result can be determined as that the verification is not passed and the bar code is read wrongly, and prompt information of the bar code reading mistake is output. When the number to be verified and the number of the verification bits meet the preset conditions, the verification result can be determined as verification passing, the bar code is read correctly, and the content of the bar code is output.
