[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a read test device, and more particularly to a read test device for a bar code reader which obtains bar code data 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.

In order to test the bar code reading stability of the bar code reader, the bar code reader is provided with a reading test mode. In the reading test mode, the bar code reader faces the bar code symbol while the bar code to be measured is stationary.
It is measured how many times the barcode was read in 0 scanning operations. Since the measurement result is displayed on the display unit (LED or LCD) of the barcode reader, the stability of the reading operation can be recognized numerically.

[0004]

SUMMARY OF THE INVENTION In the above conventional configuration,
Although the reading test is performed by reading the bar code symbol of the stationary measurement target, in the field where the bar code reader is actually used, the bar code symbol of the moving measurement target is often read. . When the measurement object is moving, disturbance factors such as changes in the moving speed and vibrations of the measurement object are added, so that the actual test stability cannot be accurately known with the conventional test configuration.

Further, in the above conventional bar code reader,
The reading test result is displayed as a percentage on the display section of the bar code reader. However, in the case where tests are continuously performed using a large number of measurement objects, it is impossible to deal with the work by looking at the display and copying it on a notebook or the like.

And has a movement test data acquisition means for measuring the number of times the decoding was possible by the first readable number measurement means, and the movement test data acquisition means has a bar code of one measurement object and a next measurement. It further comprises a timer for measuring a predetermined time period suitable for determining the separation from the target barcode, and the timer causes the first time period before the predetermined time period elapses. When it is not determined that it was possible decrypted by the constant unit,
Moving from the barcode of one measurement target to the reading test for the barcode of the next measurement target, the decoding test of the moving barcode of the measurement target and the scanning of the barcode symbol included in the stationary barcode of the measurement target do it,

A first readable determination means for scanning the barcode symbol contained in the barcode to determine whether or not the barcode symbol of the read barcode can be decoded, and the first readable determination means enables decoding. The first readable number measuring means that counts up when it is determined that the barcode symbol is decoded is repeated by the first readable determination means, and the decoding determination of the bar code symbol is repeated. The number of times is measured by the first readable number measuring means, a reading test of the moving bar code of the measuring object is performed, and in the moving test mode, In addition, when the built-in timer operates, and the timer does not determine that the decoding is possible by the first determination means before the predetermined time elapses, the next barcode is moved from the moving measurement target barcode. In the stationary test mode, the bar code symbol included in the stationary bar code of the measurement target is scanned to determine whether the bar code symbol of the read bar code can be decoded. The second readable determination unit that determines whether or not the second readable determination unit that counts up when the second readable determination unit determines that the second readable determination unit was able to decode the second readable determination unit operates to operate the second readable number.

[0010]

In the reading test apparatus according to the first aspect of the present invention, the decoding determination of the bar code symbol contained in the moving bar code of the measuring object is repeated, and the number of times the decoding is possible is repeated by the first readable number. By a timer that measures a predetermined time suitable for determining the separation between one measurement target barcode and the next measurement target barcode by a measuring means, When it is not determined that the decoding of the code symbol was possible, the bar code of the moving measuring object is moved to the reading test for the bar code of the next measuring object from the one moving measuring object bar code, and the moving measuring object bar code decoding test, A bar code of a stationary measurement target that scans the bar code symbol contained in the bar code of a stationary measurement target and measures the number of times that the decoding was possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, a bar code reader 1 to which an embodiment of the present invention is applied irradiates a laser beam 5 toward a bar code symbol 4 of a bar code label 3 attached to a measuring object 2. It is like this. The measuring object 2 is
It may be mounted on a mounting table (not shown) or may be movable by a belt conveyor (not shown) or the like.

On the front surface of the bar code reader 1, an LCD 6 for display and a teach key 7a for designating a teach mode are provided.
And a switch group 7 including a code input key 7b for inputting an output code. Further, on the side surface of the barcode reader 1, there are first to third connectors 11 for external connection.
~ 13 are provided. A programmable controller 10 (an example of a signal output target) is connected to the first connector 11 via a cable 9. 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. The handy barcode reader 15 is equipped with the same configuration as the laser reading means (described later) of the barcode reader 1.

Incidentally, instead 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 may be connected as necessary. As shown in FIG. 2, the bar code reader 1 has a semiconductor laser diode 21 for irradiating the bar code 4 with a laser beam 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 scans the barcode symbol 4 via the scanning unit 24 having the polygon mirror 23. 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 input to the light receiving circuit 26 that performs analog processing such as signal shaping.

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 from the light receiving circuit 26 is input to the. In the reading processing unit 27, the laser lighting circuit 22 is set at a predetermined timing.
Also, the scanning unit 24 is driven and the input signal from the light receiving circuit 26 is digitized. The digitized barcode signal is output to the analysis processing unit 30.

The analysis processing section 30 includes an operation panel including an LCD 6 and a switch group 7, a memory 31, and an interface 32 to 31 having first to third connectors 11 to 13.
34 are connected. The memory 31 includes a reference table area for a reference bar code or an output code that serves as a reference for comparison, a set digit storage area, and a buffer area for temporarily storing input data.

The analysis processing section 30 executes various processes (described later) such as comparing the measured bar code with a stored reference bar code. As a processing result, the signal such as the comparison result of the measurement barcode and the reference barcode,
It is output to the programmable controller 10 or the like via the interface 32. Also, the interface 33
Also, the measurement barcode information is output. 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 interface 34 via the third connector 13. Instead of the handy bar code reader 15, a keyboard 15a, another bar code reader 15b, or a personal computer 15c may be connected to output bar code data from those devices to the analysis processing unit 30.

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, by operating the switch group 7, it is determined 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.

When the timing signal TIM is turned on, the program shifts from step S1 to step S8. In step S8, it is determined whether or not the teach mode command TCH is issued. In the measurement mode, since the teach mode command has not been issued, the process proceeds to step S9 and the measurement process shown in FIG. 5 is performed. 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 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 18
Outputs an output signal to the light receiving circuit 26. The light receiving circuit 26 shapes and amplifies the input signal and outputs it to the reading processing unit 27. The reading processing unit 27 digitizes the input signal,
Output to the analysis processing unit 30.

In step S22, the bar code symbol 4 is decoded based on the read data. Here, a digit setting operation described later (step S4 and step S1 in FIG. 4).
Bar code symbol 4 for the digit part set in 8)
Decipher. That is, here, since the decoding operation is performed only for the preset digit portion, the decoding process is speeded up and simplified.

When the decoding process in step S22 is completed,
In step S23, it is determined whether the barcode symbol 4 can be read. If it is readable, the process proceeds to step S24. Step S2
In 4, the read data is once 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. Step S2
When the process in 4 is completed, the process returns to the main routine of FIGS.

If it is determined in step S23 that the data cannot be decrypted, the process proceeds to step S25. In step S25, the timing signal TIM is still ON.
Judge whether or not. Timing signal TIM is O
While it is N, the process returns to step S21 and the reading operation of the barcode symbol 4 is repeated. Barcode symbol 4
Timing signal TIM is OF
If F, 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, since the reading operation ends without being able to decode the data, "0" is written in the leading address. When the processing in step S26 ends, the process returns to the main routine of FIGS.

On the other hand, it is determined in step S61 of FIG. 9 whether or not there is an external data input to the third connector 13. 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 output to the buffer of the memory 31. 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 data has been written in the buffer of the memory 31. If the data is written in the buffer, the process proceeds to step S72. Step S
At 72, it is determined whether or not the read data is decodable 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, a preset digit portion (step S in FIG.
4 and step S18), the reference bar code (preset value) stored in the preset area of the memory 31.
And the read data in the buffer are compared. here,
Since the comparison operation is performed only for the preset digit portion, the amount of comparison processing is small, and the time required to complete the processing can be shortened.

Next, in step S75, an OK output indicating that the reading was possible is output via the interface 32. The LCD 6 also displays OK. In step S76, it is determined whether the read data for the set digit portion matches the reference bar code.
If they match, in step S77, a comparison result indicating which reference bar code matches (specifically, 1 to 31).
Values in the reference table (FIGS. 11 and 1) described later.
Based on 2), output through the interface 32. 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. Step S
In 72, 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 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 interface 32. Also, L
It is also displayed on the CD 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 processing in steps S27 to S29 is 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. At the beginning of the teach mode, the print address Ap is "1", so 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 preset address A
Clear the data of p. When the process in step S30 or step S32 is completed, the process proceeds to step S11 in FIG. In step S11, the preset address A
Increment p. The preset address A
When p is "31", it is set to "1".

When the depression of the teach key 7a is released, the process proceeds from step S2 to step S12 in FIG. 3 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. In step S61 of FIG. 9, the third connector 1
When it is determined that there is a port input from the outside through the No. 3, 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 reader 1 itself.

Steps S77 and S78 (see FIG. 1)
When the output code Co output in 0) is changed, the switch group 7 is operated to enter the output code 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. Also, step S
At 15, it is determined whether or not the end of the output code mode is instructed. Furthermore, in step S16, "1"-
It is determined whether or not the preset address Ap of "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 main power 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".

Based on the reference table set as shown in the example (A) or the example (B) of FIG. 12, the output code Co is output in step S77 or step S78 of FIG. The output code Co can be changed freely, and the degree of freedom of the output code Co is high. Therefore, it becomes possible to freely perform sorting control in units of groups and output coincidence / non-coincidence with preset values of read data, which simplifies a program in an external device (programmable controller 10 or the like) connected to the interface 32. You will be able to plan. Also,
By directly connecting the lamp or the like without connecting the programmable controller 10, it is possible to control the lighting of the lamp.

On the other hand, if a reset command is issued, the process moves from step S13 to step S14 in FIG. 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 "31"). If an end command is issued, the process returns from step S15 to the main routine.

Step S22 (FIG. 5), step S28
If the setting digit setting command used in (FIG. 6) and step S73 (FIG. 10) is executed by operating the switch key group 7, the program proceeds from step S4 to step S18 in FIG. In step S18, L
The message “Please set the digit. From which digit?” Is displayed on the CD 6, and the operator is prompted to input the digit and the desired digit number 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 digit set here is used in step S22 and the like, it is possible to eliminate the waste of processing required for unnecessary portions of the barcode data. For example, JA
In the N code, a bar code is composed of a country code, a maker code, a product code and a check digit, but in many cases, only the product code is desired to be processed. In that case, by setting the digit range of the bar code corresponding to the product code in step S18, efficient bar code reading processing using only the bar code related to the product code can be executed. When the movement test mode is instructed by operating the test mode switch group 7, the process moves from step S5 of FIG. 4 to step S19, and 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 of the read barcode can be decoded.

In step S45, based on the processing in step S44, it is determined whether or not all bar code symbols could be decoded. If the decryption is possible, the process moves to step S49 and the variable i is incremented. In step S50,
Reset the timer T. If it is determined in step S45 that the barcode could not be read, or if the processing in step S50 ends, step S46.
Move to. In step S46, the timer T is set to 0.3.
Judge whether it is more than a second. Here 0.3 seconds is
When it is assumed that the reading operation can be performed 300 times per second, the time is appropriate for determining the separation between the barcode of one measurement target and the barcode of the next measurement target. While the timer T has not reached 0.3 seconds, it can be determined that the barcode data is being read from one barcode, so the process returns from step S46 to step S43, and the barcode reading operation from step S43 onward is repeated.

When the timer T exceeds 0.3 seconds and it is judged that the reading of one bar code is completed, the process shifts from step S46 to step S47. Step S47
Then, a variable i indicating the number of read times for one barcode
The read barcode is displayed on the LCD 6 and is 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 stability of reading when the measurement 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, not only the count value (variable i) and the bar code are displayed on the LCD 6 but also output to the outside through the interface 33, so by connecting an appropriate external device, a high-speed repeated reading test is supported. become able to.

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

In step S54, 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, step S53
If the determination is No, the process proceeds to step S55 without performing the process of step S54. In step S55, the variable j is incremented to count the total number of readings. Then, in step S56, the variable j
Is determined to be "100". The variable j is “1
Until "00", the process returns to step S51, and the reading process from step S51 onward is repeated. When the variable j becomes "100" in step S56, the process proceeds to step S57.

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.
