Description

  The present invention relates to a barcode input system for inputting data by reading a barcode attached to an article or the like, and more particularly to a barcode input system capable of collecting data of barcode reading failure. . Here, the barcode input system includes, for example, a POS system in which a plurality of POS terminals are connected to a server device, and a similar system such as logistics using a barcode, product management, and the like.

  In store systems that manage products using barcodes, managing products by inputting barcode data attached to products has been an effective means for improving operability. However, in this type of system, if a problem in reading barcode data occurs, it will hinder the smooth operation. Therefore, it is important to analyze the cause of the reading failure in order to improve the barcode reading rate.

  Major factors of bar code reading failure include poor printing of bar code labels, mechanical problems of the reading device, and operational problems of the operator reading the bar code label. Hereinafter, a store system including a server device and a plurality of POS terminals will be described as an example. The POS terminal generally receives “bar code type” and “bar code data” as input information from a bar code reader connected to the POS terminal. If it cannot be read, an “error code” is received. Just receive. Therefore, when a barcode reading error occurs, it is unknown which barcode has caused the reading error.

In general, when a barcode reading error occurs, the operator performs an operation of inputting the product code from the keyboard while looking at the barcode label. Accordingly, in this case, since the POS terminal cannot obtain data other than “error code” from the barcode reader, it takes time and man-hours to investigate the cause of which barcode label cannot be read. This is because of the following reason.
(1) The product is taken home by the shopper and it is difficult to obtain the barcode label.
(2) The operator is busy in judging the shopper such as product registration and payment, and it is difficult to remember and specify the product after the operation is completed.
(3) The content of declaration may vary depending on the operator.

  Therefore, it is necessary to distinguish whether the barcode reading error is caused by the barcode label itself, the reading performance of the barcode reader, or due to individual differences such as the operator's habit. It is essential to obtain information about which device the label is on and which operator is operating the error.

  In relation to poor barcode reading, for example, Patent Document 1 discloses a POS system that reads a barcode attached to a product at a lower recognition level. In this system, when the barcode reader cannot read the barcode, the barcode is read at a lower level. When the barcode is read in this state, the barcode data based on the barcode and the recognition level are lowered. Information is transmitted, and if it cannot be read even if the recognition level is lowered, information to that effect is transmitted. On the other hand, when the information indicating that the recognition level has been lowered is received together with the barcode data, the POS terminal outputs the content corresponding to the barcode data and issues an instruction for confirming whether or not the output content is appropriate. When only the information indicating that it could not be read is received, a code input instruction by an external operation is issued.

  Patent Document 2 discloses a reading device used in a POS system that can be operated in accordance with personal characteristics such as an operator's habit and rhythm. This device collects the setting information for each operator according to the personal characteristics of the operator in the operation, and the operation is based on the operation standard set based on the setting information for each operator corresponding to the operator before the operation. Since the operation criteria are satisfied with the operation specific to the operator, the occurrence rate of code reading errors can be reduced, and the operation efficiency can be increased. is there.

  Further, Patent Document 3 discloses an optical information reading apparatus capable of notifying the user of the cause when an optical information reading error occurs. This apparatus is configured to analyze the cause of the reading error that cannot be decoded by the analyzing means, and to notify the cause of the reading error by the notifying means based on the analysis result. According to this, since the cause of the reading error is notified to the user, it becomes easy for the user to cope with the cause, and thus optical information that cannot be read can be reduced.

In addition, in order to facilitate the analysis of bar code reading errors, a bar code reader recently reported an intermediate (gray) condition that “bar code data could be read but printing was in violation of Japanese Industrial Standards”. A bar code reader is coming out. According to this, it is possible to identify a bar code label having a potential of poor print quality, but it is expensive to replace the old apparatus with the new apparatus. Further, even with this apparatus, it is not always possible to read all cases, and finally, an operation of re-inputting with a keyboard is required.

Examples according to the present invention will be described below. In this embodiment, a POS system will be described as an example of a barcode input system.
FIG. 1 is a diagram showing an embodiment of a POS system according to the present invention. The present embodiment relates to a POS system (store system) including a plurality of POS terminals and a server device. POS terminals 11, 12, 13... Installed in the store have identification numbers of POS terminal numbers (No.) 01, 02, 03..., Respectively, and are connected to the server device (store server) 10. ing. Sales data and the like processed at each POS terminal are sent to the server device 10, respectively, where the entire store is totaled and managed. Each POS terminal has a barcode reader and keyboard as input means for barcode label data attached to the product, and a product master in which a product code corresponding to the barcode is registered in a storage device such as a hard disk. ing. Details of the product master will be described later.

  In the present embodiment, in the server device 10, the POS terminal number sent from each POS terminal 11, 12, 13; the operator number related to the operation; the type of the input means of the operated barcode reader or keyboard; the barcode Journal data 6 in which the read result code and the product input code are recorded in time series as a record is created. Then, records are sequentially read from the journal data 6, and when the input means of the read records indicates a keyboard and the input code matches the product code registered in the product master, the record immediately before the read record is read, When the input means of the immediately preceding record is a barcode reader and the barcode reading result code indicates a reading error, the number of reading errors related to the POS terminal number and operator number of the previously read record is counted up and classified by product code Aggregate to create a summary table 7. From this tabulation table 7, it is possible to perform a statistical analysis of the cause of barcode reading failure, and for example, it is possible to estimate a barcode label that has caused barcode reading failure. Details of the journal data 6 and the summary table 7 will be described later.

FIG. 2 is a diagram illustrating a configuration example of the POS terminal in FIG. As shown in the figure, the POS terminal of this example includes a barcode reader (BCR) 21 that reads a barcode label 20 attached to a shopping product, a display device 22 that displays a reading result, a control device 23 that performs various controls, A keyboard (KB) 24 for manual input, a printer 25 for printing receipt paper, and a cash drawer 26 for storing cash are provided. The control device 23 and each device are connected by a cable or the like. In a general POS terminal operation, the bar code label 21 is read by the operator's operation, and the read data is sent to the control device 23. The control device 23 includes a product master 3 stored in a storage device such as a hard disk. The control device 23 determines the product name and price from the product master 3 based on the read data, and displays them on the display device 22. The shopper pays a fee commensurate with the price displayed on the display device 22. The operator receives a fee from the shopper, inputs the amount with the keyboard 24, issues a receipt paper with the printer 25, takes out change from the cash drawer 26 as necessary, and hands it to the shopper. In this example, the product master 3 is provided inside the control device 23, but may be provided outside.
Here, when the barcode reader 21 cannot read the barcode label 20, the operator performs a payment operation similar to the above after inputting the commodity code printed on the barcode label 20 with the keyboard 24.

  In the present invention, when a barcode reading failure occurs, the label is estimated from the following phenomenon. First, when a barcode reading error occurs, the operator tries the same reading several times, and when the reading error still occurs, the operator performs an operation of inputting the product code from the keyboard while looking at the barcode label. Using the regularity, the product code input from the keyboard is regarded as a barcode reading error. In addition, there is a case where a product code is assigned to a one-touch key for a product or the like to which a barcode cannot be attached. For this reason, in order to improve the accuracy of reading error estimation, refer to the previous event from the input journal, and if the bar code reading error event is traced and the information entered on the keyboard is a product code, It is presumed that the keyboard reading error occurred when the barcode reading error occurred. In particular, the operation at the POS terminal does not register the next product unless the registration of one product is completed in sequence, and this estimation is in a range where there is no practical problem.

  FIG. 3 is a diagram showing an example of the format of the product master 3 stored in the storage device in the POS terminal. Here, the product code 301 stores the product code corresponding to the barcode printed on the product, the product name 302 stores the product name related to the product code, and the price 303 stores the price related to the product code. Yes. For example, in FIG. 3, a product code of 49A indicates that the product name is A and the price is 980 (yen).

  FIG. 4 is a diagram showing an example of a barcode data telegram 50 sent from the barcode reader 21 used in the present invention. The barcode data telegram 50 is read by the barcode reader 21 and is composed of a result code 501 and an input code 502 as described below.

  The result code 501 is print quality data of the barcode, which is processed and determined by the barcode reader 21 when the barcode is read, and is encoded as “OK” (normal) or “NG” (read error). Sent to. Here, “OK” indicates that the barcode printing state is good in accordance with Japanese Industrial Standards and that the barcode reader 21 can read the barcode normally. “NG” was not able to read the bar code normally due to the bad bar code printing condition, specification violation, machine accuracy problem of the bar code reader 21, or unfamiliarity with the operation of the operator. Means. However, only the information of the result code 501 is unclear as to which product code “NG” is generated and which barcode label is generated.

  The input code 502 mainly includes a product code. However, depending on the operation, the input code 502 can include a membership card, an employee card, and the like, and it is possible to distinguish whether it is a product code based on the input status, the number of digits, the head code, and the like. In the following, unless otherwise specified, the contents of the barcode input are mostly product codes, so the description will be limited to product codes. The product code is a code attached to the product, and is used when the control device 23 searches for the product name and price based on the product master 3.

  FIG. 5 is a diagram illustrating an example of journal data 6 relating to product code input in the server device 10. The server device 10 totals the sales data from the POS terminals 11, 12, 13... The journal data 6 includes a POS terminal number (No.) 601, sales date information 602, sales number operator number (No.) 603, bar code reading operation input means 604, bar code reading result code. 605, each of an input code 606 of a product generally represented by a numeric string as an input code, and a product name 607 field.

  As shown in the figure, the journal data 6 includes a POS terminal No. 601, date and time information 602, and operator No. Each record is shown as a plurality of records 603 in which data is recorded in order of time. When the operation is immediately sent to the server device 10 in the registered transaction unit in the POS terminal, the journal data 6 is stored in the POS terminal No. 601, operator no. 603 is stored separately.

  In FIG. 5, for example, a record 61 includes a POS terminal No. that has recorded sales. 601 is “01” and the operator number of the operator is set. 603 indicates “003”, the input means 604 indicates “BCR” (barcode reader), the read result is “OK” (normal), the product input code is “49A”, and the product name is “A”. Further, when the record 62 is compared with the record 61, the POS terminal No. 601, operator no. 603, the input means 604, and the result code 605 are the same, but are different in that the product input code 606 is “49B” and the product name is “B”. The record 63 is the same as the record 62 except for the date / time information 602. Since the record 64 could not be read by “BCR” as the input means 604, an example in which the result code 605 is “NG” (read error) is shown. Since the record 65 cannot be read by the “BCR” that is the input means 604 of the record 64, the product input code consisting of a numeric string is manually input using “KB” (keyboard) as the input means 604. Indicates. In this case, the product input code 606 is “49C” and the product name 607 is “C”. The record 66 has the POS terminal No. that recorded the sales. 601 is “02” and the operator No. 603 is “003”, the input means 604 is “KB” (keyboard), and the product input code 606 is “49X”, but the code that matches the product input code is the product master 3 of the server device 10 or the POS terminal. In this case, the product name 607 is “(blank)”. Record 67 indicates the POS terminal No. that recorded the sales. 601 is “02” and the operator No. 603 is “003”, the input means 604 is “KB” (keyboard), and the product input code 606 is “F1 key”. The “F1 key” indicates that the product preset key code of the product preset key table (not shown) is input. In this case, the product name 607 is “A”.

  FIG. 6 is a diagram showing a tabulation table in which various data are tabulated. The tabulation table 7 is based on the journal data 6 and is classified by product code, POS terminal No. Another operator No. Separately, the bar code reading results are totaled. A computer program for creating the summary table 7 is installed in the server device 10, and the created summary table 7 is stored in a storage device such as a main memory or a hard disk in the server device 10. In the figure, a product code 701 indicates a product code recognized by the input code 606 (for example, 49A), and the number of readings 702 indicates the number of times the product code 701 has been recognized by the input code 606 (for example, 100 times). No. The separate error count 703 is the POS terminal No. with “NG” in the result code 605. Another error count (for example, 10 times for POS terminal No. 01) is set to the operator No. The separate error count 704 is the operator number corresponding to “NG” in the result code 605. The number of different errors (for example, 5 times for operator No. 001) is shown.

  According to this tabulation table 7, the POS terminal No. for each product code can be obtained from the current input data without introducing a new device. Another operator No. Separately, the number of barcode reading errors can be known. As a result, the cause of the barcode reading error can be analyzed by a statistical method for each barcode label, each POS terminal, and each operator. That is, it is possible to know whether the barcode reading error is caused by the barcode label itself, due to the reading performance of the barcode reader, or due to individual differences such as an operator's habit.

  7, 8 and 9 are flowcharts for creating a summary table from journal data according to an embodiment of the present invention. By performing the processing according to this flowchart, the total table 7 of FIG. 6 is created for each product code from the journal data 6 of FIG. This is executed by a computer program stored in the server device 10, for example.

  In FIG. 7, first, records are sequentially read from the input journal data 6 (S801), and it is checked whether the input means 604 of the journal data 6 is “KB” (S802), and if it is “KB”. For example, the input code 606 of the journal data 6 is set in the work area (work area) in the control device 23 (S803). Subsequently, the product master 3 is searched with the information of the work area (S804). Then, it is checked whether or not the product master 3 is hit with the information of the work area (S805), and if it is hit, the read count 702 of the corresponding product code corresponding to the work area information of the summary table 7 is incremented by (+1). (S806). Next, the previous record read in step S801 is read (S807). Here, it is checked whether or not the input means 604 of the journal data 6 is “BCR” (S808). If it is “BCR”, it is next checked whether the result code 605 of the journal data 6 is “NG” (S809). If it is “NG”, the POS terminal No. of the journal data 6 is displayed. 601 and operator no. From 603, the corresponding POS terminal No. of the corresponding product code 701 in the summary table 7 is displayed. Another error count 703 and the corresponding operator No. Each of the other error counts 704 is incremented by (+1) (S810), and the process ends. As a result, the error occurrence rate can be known from the ratio of the read count 702 and the error counts 703 and 704.

  On the other hand, if the journal data 6 input means 604 is not "KB" in step S802 (S802), it is checked whether the journal data 6 input means 604 is "BCR" (S820). If it is “BCR”, it is checked whether the result code 605 of the journal data 6 is “OK” (S821). If it is “OK”, the input code 606 of the journal data 6 is set in the work area in the control device 23 (S822). The product master 3 is searched with the information of the work area (S823). Then, it is checked whether or not the product master 3 is hit with the information of the work area (S824). If there is a hit, the read count 702 of the corresponding product code corresponding to the work area information of the summary table 7 is incremented by (+1). (S825) and the process ends.

  As described above, the total number of times each processed product code is read is counted in steps S806 and S825, and in step S810, the number of errors is counted corresponding to the product code regarded as an error. Become.

  Similarly, as other processing routes, records are sequentially read from the input journal data 6 (S801), the input means 604 of the journal data 6 is not "KB" (S802), and the input means 604 of the journal data 6 is used. Is not “BCR” (S820), the process ends. Further, records are sequentially read from the input journal data 6 (S801), the input means 604 of the journal data 6 is not “KB” (S802), and the input means 604 of the journal data 6 is “BCR” ( If the result code 605 of the journal data 6 is not “OK” (S821), the process ends. As described above, after the flow ends, the next record processing is executed.

  In this way, by regarding the product code input from “KB” as a barcode that has caused a reading error, it is possible to collect information on the barcode reading failure rate by product code, by POS terminal, and by operator. As a result, based on these data, it is possible to analyze the cause of read failure by a known statistical method such as multivariate analysis (determination of deviation from expected value by scatter diagram, regression analysis, etc.). As a result, it is possible to estimate inherent factors such as a product code label, a POS terminal, and an operator.

  This embodiment can be executed by a computer program. In this case, the computer uses a POS terminal number sent from a plurality of POS terminals having a bar code reader and keyboard input means and a merchandise master registering a merchandise code corresponding to the bar code, an operator number related to the operation, and an operation. A means for sequentially reading the records from the journal data in which the type of the input means, the barcode reading result code, and the product input code recorded in time series as a record; and the input means for the read record is a keyboard And when the input code matches the product code registered in the product master, the record immediately before the read record is read, and the input means for the immediately preceding record is a barcode reader and the barcode When the read result code indicates a read error Comprising a program for functioning as means for aggregated by product code counts up the read error count according to the POS terminal number and operator number of the read record. This program is stored in a computer-readable recording medium such as a CD-ROM, or can be downloaded by uploading via a telecommunication line such as the Internet, and can be installed in a POS terminal or server device as appropriate.

  As described above, in this embodiment, the store system in which a plurality of POS terminals are connected to the server device has been described as an example. However, the present invention is not limited to this, and other bar code input systems such as a bar code system, for example, It can also be applied to similar systems such as logistics and product management using codes. The present invention is not limited to the client server system described above, but can be applied to an independent single device having a barcode reading function in which a barcode input terminal (POS terminal) and a server device are integrated. is there. In this case, analysis for each barcode input terminal (POS terminal) is unnecessary.

  Further, in this embodiment, the “NG” barcode specifying method is determined by the combination of the keyboard (KB) input and the previous barcode reader (BCR) input result. It may be within a predetermined range immediately before that. For example, when a number of KBs are input several times before this, a recent BCR input result that goes back may be used.

  Furthermore, depending on the operation, for example, when the barcode cannot be read, it is recommended that the product is temporarily held, the next product is processed, and finally the unreadable product is input from the KB. If it is, it may be performed in combination with the BCR input result within the same transaction. The transaction in this case is a unit in which a plurality of product code inputs (including cases where there is an error) are performed for each shopper and payment is finally performed. This unit can be set to the immediately preceding predetermined range. Obviously, if it is known that the barcode is damaged, it is possible to input from the KB from the beginning, and only the KB input data and it indicates the product code. The case is also applicable. The estimation error associated with these determinations can be applied within a practical range.

  The present invention can be used in a bar code input system for managing sales of merchandise, and without introducing a new reading device, from the current input data, the bar code input terminal No. Another operator No. Separately, the number of barcode reading errors can be known. As a result, the cause of the barcode reading failure can be analyzed by a statistical method for each barcode label, each barcode input terminal, and each operator. From this analysis result, it is possible to take measures to avoid a barcode reading failure, so that an efficient operation of the barcode input system can be realized.
