Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code data processing device for processing bar code data obtained from a bar code to be measured.

[0002]

2. Description of the Related Art A bar code is a code that represents characters such as numbers by arranging bar-shaped images called bar code symbols, and was developed for use in a distribution information system. The bar code reader scans the vicinity of the center of the bar code symbol with a laser beam and measures the width of the bar code symbol to read the code. This bar code reader is usually obtained by a scanning unit having a laser light source that emits a laser beam and a polygon mirror, a receiving unit that receives the laser beam reflected from the barcode to be measured and converts it into an electric signal, and a receiving unit. And a decoder for decoding the received electrical signal.

The bar code reader decodes all bar code data based on the laser light reflected from the bar code to be measured by a decoder and outputs the bar code data to a host computer, a programmable controller or the like. An upper host computer or programmable controller that has received the barcode data performs processing of removing unnecessary data portions from all barcode data, and performs subsequent processing using the remaining required barcode data portions.

[0004]

In the above conventional bar code reader, all the acquired bar code data is output to the upper device irrespective of whether it is necessary or unnecessary. Therefore, the unnecessary part is removed on the upper device side. The process of leaving the necessary parts is required, and the burden on the software on the upper device side is heavy. Further, since the unnecessary bar code data portion is also communicated, the communication processing load is large.

An object of the present invention is to eliminate waste of processing required for unnecessary portions of bar code data.

[0006]

A schematic configuration of a bar code data processing apparatus according to the present invention is shown in FIG. 1 (b). FIG.
In (b), the bar code data processing device 1 includes a valid digit receiving means 7c that receives designation of a valid digit of the barcode data, and a valid digit storage unit 31a that stores the valid digit.
And analysis processing means 30A for processing the barcode data. The analysis processing means 30A processes the bar code data based on the effective digits stored in the effective digit storage unit 31a.

[0007]

In the bar code data processing device 1 according to the present invention, the valid digit receiving means 7c receives the designation of the valid digit of the bar code data and stores it in the valid digit storage section 31a. When the bar code data is obtained in the state where the significant digit is stored, the analysis processing means 30A reads the significant digit from the significant digit storage section 31a and processes the bar code data based on the designation of the significant digit. As a result, the bar code data can be divided into the necessary part and the unnecessary part based on the designation of the effective digit, and the waste of the processing required for the unnecessary part of the bar code data can be omitted.

[0008]

On the front surface of the bar code data processing device 1,
An LCD 6 for display and a switch group (effective digit acceptance means) 7 including a teach key 7a for designating a teach mode, a code input key 7b for inputting an output code, and the like are arranged. In addition, on the side surface of the barcode data processing device 1,
First to third connectors 11 to 13 for external connection are provided. The programmable controller 10 is connected to the first connector 11 via the cable 9 (an example of a signal output target).
Is connected. A handy barcode reader 15 is connected to the third connector 13 via a cable 14. The handy bar code reader 15 can be grasped by an operator with his / her hand to freely change the orientation and position of the cable 14 within the allowable range.

In place of the programmable controller 10, an input terminal of a personal computer or a drive driver circuit (not shown) such as a lamp group for notifying an operator can be connected as necessary. As shown in FIG. 2, the bar code reader unit 20 has a semiconductor laser diode 21 for irradiating the bar code 4 with the laser light 5. The semiconductor laser diode 21 is driven by the laser lighting circuit 22, and the laser light 5 from the semiconductor laser diode 21 is reflected by the polygon mirror 23.
The barcode symbol 4 is scanned via the scanning unit 24 having The laser light 5 reflected by the barcode symbol 4 is received by the light receiving element 25 which is a photoelectric conversion element such as a photodiode. The output signal of the light receiving element 25 is a light receiving circuit 2 that performs analog processing such as signal shaping.
6 is input.

The laser lighting circuit 22 and the scanning section 24 are driven by the reading processing section 27. Further, the reading processing unit 27
A detection signal (analog signal) from the light receiving circuit 26 is input to. The reading processing unit 27 drives the laser lighting circuit 22 and the scanning unit 24 at a predetermined timing, and
The input signal from the light receiving circuit 26 is digitized. Digitized bar code signal (bar code data)
Is output to the analysis processing unit (CPU) 30.

The analysis processing unit 30 is connected to an operation panel including an LCD 6 and a switch group 7, a memory 31, and first to third interfaces 32 to 34 having first to third connectors 11 to 13. There is. The memory 31 includes a reference bar code or output code reference table area serving as a reference for comparison, an effective digit storage area (effective digit storage unit), and a buffer area for temporarily storing input bar code data. I'm out. Switch group (operation panel) 7
Is capable of designating a significant digit that designates a necessary part of the barcode data. The effective digit input from this switch group (operation panel) 7 is
It is stored in the effective digit storage area of the memory 31. The analysis processing unit 30 stores the input barcode data in the memory 3
Processing is performed based on the significant digit stored in 1. The bar code data in this specification means information in which the lightness and darkness of a bar code is binarized (digitized), alphanumeric information (decoded), or information in which only significant digits are extracted from alphanumeric information. . In addition, the processing of the bar code data refers to processing of converting the binarized information into alphanumeric characters (decoding), extracting a significant digit, reading an output code from the bar code data, and the like.

The analysis processing section 30 includes a decoding processing means 30a and a comparison processing means 30b. Decoding processing means 3
Reference numeral 0a is for fetching and decoding the binarized information from the read processing unit 27 and converting it into alphanumeric bar code data. In the measurement processing of FIG. 5 and the preset processing of FIG. The effective digit stored in is read out, and only the effective digit portion is decrypted. On the other hand, the comparison processing means 30b shown in FIG. 2 stores reference bar code data (alphanumeric information) stored in the memory 31 in advance,
The effective digit stored in the memory 31 is read out, and only the effective digit portion of the alphanumeric information is read, and the decoding processing means 30a.
The barcode data (alphanumeric information) of only the effective digit portion decoded by is compared and the comparison result is output (step S73 in FIG. 10). As a processing result, a signal such as a comparison result between the measurement barcode and the reference barcode is output to the programmable controller 10 or the like via the first interface 32. The measurement barcode information is also output to the second interface 33. Therefore, when an information device (not shown) such as a personal computer is connected to the second connector 12, the bar code information is transferred to the control device.

Bar code data from the handy bar code reader 15 is input to the third interface 34 via the third connector 13. The handy barcode reader 15 has the same configuration as the barcode reader unit 20. In addition, handy bar code reader 1
Instead of 5, the setting device 15a and another barcode reader 15
By connecting the personal computer 15b or the personal computer 15c, the bar code data from those devices can be analyzed by the analysis processing unit 3
It can also be output to 0.

Next, the operation of the above-described embodiment will be described by dividing it into a measurement mode, a teach mode and a test mode, with reference to control flowcharts (FIGS. 3 to 10) of the analysis processing section 30. The measurement mode analysis processing unit 30 determines whether or not the timing signal TIM is ON in step S1 of FIG. In step S2, the teach key 7 of the switch group 7
When a is pressed by the operator, the teach mode command T
Judge whether or not CH is performed. In step S3, it is determined whether or not the input of the output code is instructed by operating the code input key 7b.

Subsequently, in step S4 of FIG. 4, the switch group 7 is operated to determine whether or not a digit setting command for setting the effective digit portion of the read bar code is issued. In step S5, by operating the switch group 7, it is determined whether or not an instruction to execute a movement test for performing a reading test while moving the measurement target is instructed. Further, in step S6, it is determined whether or not a stationary test command for performing a reading test with the measurement target stationary is issued. In step S7, other processing is executed, and when the processing is completed, the processing returns to step S1 in FIG.

In step S1, the timing signal T
When IM turns ON, the program moves to step S8. In step S8, it is determined whether or not the teach mode command TCH is issued. In measurement mode,
Since the teach mode command has not been issued, step S
Then, the process shifts to 9 to perform the measurement process shown in FIG. In the measurement process of FIG. 5, the barcode symbol 4 of the measurement object 2 is read in step S21. Here, the semiconductor laser diode 21 of FIG. 2 emits light, and the polygon mirror 23 rotates, so that the barcode symbol 4 is scanned by the laser beam 5. According to the reflected light from the bar code symbol 4 that has entered the light receiving element 25,
The light receiving element 25 outputs an output signal to the light receiving circuit 26. In the light receiving circuit 26, the input signal is shaped and amplified, and the read processing unit 2
Output to 7. The reading processing unit 27 digitizes the input signal and outputs it to the analysis processing unit 30.

When the reading in step S21 in FIG. 5 is completed, the process proceeds to step S22. In step S22, the bar code data is decoded based on the read data (bar code data). Here, the bar code data is decoded for the effective digit portion set in the digit setting operation (step S4 and step S18 in FIG. 4) described later. That is, here, since the decoding process for converting the binarized bar code data into the alphanumeric information only for the preset effective digit portion is performed, the decoding process is speeded up and simplified. The decryption is performed by the decryption processing means 30a shown in FIG.
Do.

When the decoding process in step S22 of FIG. 5 is completed, it is determined in step S23 whether or not the barcode symbol 4 could be read. If it is readable, the process proceeds to step S24. In step S24, the decoded data is temporarily output to the buffer of the memory 31. At this time, the head address is set to "1" to indicate that the data was readable. When the processing in step S24 ends, the process returns to the main routine of FIGS.

If it is determined in step S23 of FIG. 5 that the data cannot be decrypted, the process proceeds to step S25.
In step S25, it is determined whether the timing signal TIM is still ON. Timing signal TI
While M is ON, the process returns to step S21 and the reading operation of the barcode symbol 4 is repeated. When the bar code symbol 4 cannot be decoded, the timing signal TIM
If is turned off, the process proceeds from step S25 to step S26. In step S26, the error data indicating that the decoding is impossible is output to the buffer of the memory 31. Here, the reading operation ends without being able to read, so
"0" is written in the head address. When the processing in step S26 ends, the process returns to the main routine of FIGS.

On the other hand, it is judged in step S61 in FIG. 9 whether or not there is an external data input to the third connector 13 in FIG. If there is an external input, the process proceeds from step S61 to step S62. In step S62, it is determined whether the teach mode is set. Since the teaching mode is not set here, the process proceeds to step S63.
In step S63, the input data is stored in the memory 31
Output to the buffer. Here, the leading address indicating that the data could be read is set to "1". That is, the output processing to the buffer in step S63 is the same as the output processing in step S24 in FIG. 5, and there is no substantial difference in the storage state in the two buffers.

Further, in FIG. 10 showing the output processing,
In step S71, it is determined whether or not the barcode data is written in the buffer of the memory 31. When the barcode data is written in the buffer, the process proceeds to step S72. In step S72, it is determined whether the read data is readable data. This determination is based on whether or not the head address of the buffer is "1". If the read data is readable, the process proceeds to step S73. In step S73, the reference bar code (preset value) stored in the preset area of the memory 31 and the read data in the buffer are compared with respect to the preset effective digit portion (step S4 and step S18 in FIG. 4). To do. This comparison is performed by the comparison processing means 30b in FIG.
Do. Here, since the comparison operation is performed only for the part of the effective digit set in advance, the amount of comparison processing is small, and the time required to complete the processing can be shortened.

Next, in step S75 of FIG.
First OK output, which means that it was possible to read
Output through the interface 32. LCD6
Is also displayed OK. In step S76, it is determined whether or not the read data in the effective digit portion matches the reference barcode. If they match, in step S77,
A comparison result (specifically, a numerical value of 1 to 31) indicating which reference barcode is matched is output via the first interface 32 with reference to a reference table (FIGS. 11 and 12) described later. . The comparison result is also displayed on the LCD 6.

On the other hand, when it is determined in step S76 that the read data does not match any reference bar code in the reference table, the process proceeds to step S78.
In step S78, the output code Co (“0” in the example of FIG. 12) when the preset address Ap of the preset table of FIG. 12 is “0” is output. In step S72 of FIG. 10, when the head address of the buffer of the memory 31 is "0", the process proceeds to step S74. In step S74, the NG output is output to the first interface 32 and the LCD 6.

When the processing in step S77, step S78 or step S74 is completed, the process proceeds to step S79. In step S79, the read barcode itself is output via the first interface 32. Further, it is also displayed on the LCD 6 together with the output code Co. Teach mode When the teach key 7a is pressed, the teach mode is entered. Here, if the timing signal TIM is turned on, step S1 through step S8 of FIG.
Then, the process proceeds to 10 and the preset process shown in FIG. 6 is performed.

In FIG. 6, the processes in steps S27 to S29 are the same as steps S21 to S23 (FIG. 5). The processing in step S31 is the same as that in step S25 (FIG. 5). In step S30, the read data is stored in the reference table area of the memory 31. Here, as shown in FIG. 11, the storage address is the value (1 to 31) of the preset address Ap. When entering the teach mode, the preset address Ap
Is "1", the read data is stored at the address "1". On the other hand, in step S32, since it is considered that a reading error has occurred, the data of the preset address Ap is cleared. When the processing in step S30 or step S32 ends, step S11 in FIG.
Move to In step S11, the preset address Ap is incremented. When the preset address Ap is "31", it is set to "1".

If the depression of the teach key 7a is released,
The process proceeds from step S2 of FIG. 3 to step S12, and the preset address Ap is reset to "1". On the other hand, if the teach key 7a is continuously pressed, 31 reference bar codes (preset values) can be stored in the memory 31. When it is determined in step S61 of FIG. 9 that there is an external port input via the third connector 13, in the teach mode, the process proceeds from step S62 to step S64. In step S64, the input data is stored in the preset address Ap of the reference table area of the memory 31. In the process of step S64, the process of step S32 (FIG. 6) and the memory 3
No distinction is made regarding memory to 1. That is, the reference barcode can be stored while the input data from the outside via the third connector 13 is treated the same as the measurement data by the barcode data processing device 1 itself.

Steps S77 and S7 of FIG.
When the output code Co output at 8 is changed, the switch group 7 is operated to set the output code change mode. As a result, the program moves from step S3 of FIG. 3 to step S13. In step S13, it is determined whether a reset command has been issued. Further, in step S15, it is determined whether or not an instruction to end the output code change mode has been issued. Furthermore, in step S16,
It is determined whether or not the preset address Ap of "1" to "31" has been input.

If the preset address Ap is input,
The process moves from step S16 to step S17. In step S17, the output code Co associated with the preset address Ap is accepted. The output code Co that can be input here is in the range of “0” to “31”. If the output code Co is accepted, the content is written in the reference table of the memory 31. An example of the reference table in this case is shown in FIG. In the example (A) of FIG. 12, when the read data is other than the preset value, the output code is “0”, the preset address Ap is “1”,
In the case of "2" and "3", the output code is "1", and so on, and the preset address Ap is divided into six types of groups. On the other hand, in the example (B) of FIG. 12, the output code Co when the read data is something other than the preset value is “0”, and the output code Co when the read data matches any preset value. Is set to "5".

As shown in the example (A) or the example (B) of FIG. 12, the output code Co is set in step S77 or step S78 of FIG. 10 based on the set reference table.
Is output, the output code Co based on the read data is output.
Can be freely changed, and the degree of freedom of the output code Co is high.
Therefore, it becomes possible to freely perform sorting control for each group and output match / mismatch with respect to the preset value of the read data. The program can be simplified. Further, it is possible to control the lighting of the lamp by directly connecting the lamp or the like without connecting the programmable controller 10.

On the other hand, if a reset command is issued in step S13 of FIG. 3, the process proceeds to step S14. In step S14, the setting of the reference table shown in FIG. 12 is returned to the default value. Here, the output code Co is the same as the preset address Ap (that is, "0" to "3").
1 "). In step S15, if an end command is issued, the process returns to the main routine.

Step S22 (FIG. 5), step S28
If the setting command of the setting digit used in (FIG. 6) and step S73 (FIG. 10) is executed by operating the switch group 7, the program shifts from step S4 to step S18 in FIG. In step S18, the LCD
A message "Please set the digit. From which digit?" Is displayed on 6, and the operator is prompted to input the digit and the input of the desired digit is accepted. If the operator inputs the number of digits, then "Enter the number of digits. How many digits?" Is displayed on the LCD 6,
Wait for input of desired number of digits. If the operator inputs a digit range to be compared, the set digit is stored in the memory 31, and then the process returns to the main routine.

Since the effective digit set here is used in step S22 of FIG. 5 and the like, it is possible to eliminate the waste of processing required for unnecessary portions of the bar code data. For example, in JAN code, country code, manufacturer code,
A barcode is composed of a product code and a check digit, but in many cases, only the product code is desired to be processed. In that case, the digit range of the bar code (effective digit range) corresponding to the product code is determined in step S of FIG.
By setting in 18, it is possible to execute efficient decoding processing of barcode data using only the barcode relating to the product code. Test mode In step S5 of FIG. 4, when the movement test mode is instructed by operating the switch group 7, step S1
9, the movement test process of FIG. 7 is executed.

In step S41, the variable i is set to "0". Further, in step S42, the timer T is reset. In step S43, the target reading operation is performed as in step S21 (FIG. 5). Step S44
Then, the decoding process is performed similarly to step S22, but here it is determined whether or not all the symbols (including the part other than the significant digit) of the read bar code can be decoded.

In step S45, based on the decoding process in step S44, it is determined whether or not all bar code symbols could be decoded. If the decryption is possible, the process proceeds to step S49 and the variable i
Is incremented. Also, in step S49A, the timer T is reset. If it is determined in step S45 that the bar code could not be read, or if the process in step S49A ends, the process proceeds to step S46. In step S46, it is determined whether the timer T has reached 0.3 seconds or more. Where 0.3
The second is an appropriate time for determining the separation between the bar code of one measurement target and the bar code of the next measurement target, assuming that the reading operation can be performed 300 times per second. While the timer T has not reached 0.3 seconds, it can be determined that the bar code data is read from one bar code, so the process returns from step S46 to step S43, and the bar code reading and decoding operations in step S43 and the subsequent steps are performed. repeat.

If it is determined in step S46 that the timer T exceeds 0.3 seconds and the reading of one bar code is completed, the process proceeds to step S47. In step S47, the variable i indicating the number of readable times for one barcode and the read barcode are displayed on the LCD 6 and output to the second interface 33.
In step S48, it is determined whether or not the operator has given an instruction to end the movement test. Until the end command is issued, the process returns to step S41, and the measurement operation after step S41 is repeated. If the end is instructed, the process returns from step S48 to the main routine of FIGS.

In the above movement test, the number of readings in the moving state can be counted by reading the bar code symbol 4 while moving the measuring object 2. Therefore, the read test closer to the actual measurement operation can be performed, and the accuracy of the read test is improved. The count value (variable i) and the barcode output via the first interface 32 are subjected to statistical processing by an external device, for example, the average value of the number of readings is calculated and a histogram is created.

As a result, it becomes possible to recognize the reading stability when the measuring object 2 is moved.
It becomes possible to judge the necessity of correction such as reviewing the printing and sticking position of the barcode label 3 and reviewing the play and play speed. In addition, the count value (variable i) and the barcode are not only displayed on the LCD 6 but also output to the outside through the second interface 33. Therefore, by connecting an appropriate external device, a high-speed repeated reading test can be performed. Will be able to deal with.

If the static test mode is specified by operating the switch group 7 in step S6 of FIG. 4, the process proceeds to step S20 and the static test process of FIG. 8 is executed. In step S50 of FIG. 8, the variable i and the variable j are set to "0". The processing in steps S51 to S53 is the same as the processing in steps S43 to S45 in FIG.

In step S54 of FIG. 8, the variable i is incremented to count the number of times the barcode can be read, and the process proceeds to step S55. On the other hand, when the determination in step S53 is No, the process of step S54 is not performed and the process proceeds to step S55. Step S
At 55, the variable j is incremented to count the total number of readings. Then, in step S56, it is determined whether the variable j has become "100". Variable j
Until it becomes "100", return to step S51,
The reading process after step S51 is repeated. Step S
If the variable j becomes "100" at 56, step S
Move to 57.

In step S57, the variable i indicating the number of readings and the read bar code are displayed on the LCD 6 and output to the second interface 33. The process here is substantially the same as step S47 (FIG. 7).
When the processing in step S57 ends, the process returns to the main routine shown in FIGS. Here, the test conditions (moving test and stationary test) can be switched so as to be closer to the actual measurement conditions of the measuring object 2. Therefore, in this embodiment, the read test closer to the actual measurement operation can be performed, and the accuracy of the read test is improved.

In the first embodiment described above, the bar code data processing device 1 of FIG. 2 has the bar code reader unit 20 integrated therein, but in the present invention, the bar code data processing device 1 is provided.
Need not have the bar code reader unit 20. An example of this will be described with reference to the second embodiment of FIGS. 13 and 14.
