[0002] Barcode reading equipment refers to equipment used to read barcode information. It uses an optical device to convert the barcode information into electronic information, which is then translated into corresponding data information by a dedicated decoder. Due to its fast input speed, high reliability, large amount of information collection, and flexibility and practicality, barcode reading equipment has been widely used in many fields such as commodity circulation, library management, postal and telecommunications management, and banking systems.

[0058] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Example 1

[0060] like Figure 2 As shown, a three-axis automated testing method comprises the following steps:

[0061] S1: Set the motion controller and test equipment parameters.

[0062] like Figure 3 As shown, in step S1, the motion controller parameters include YZ axis step value, YZ axis moving speed, depth of field range, vertical height range, X axis reciprocating range, X axis moving speed, and X axis movement times; the test device parameters include serial port number and baud rate, and the number of test devices is greater than or equal to 1. In this embodiment, there are 4 test devices for simultaneous testing.

[0063] S2: Set the test boundary mode.

[0064] In step S2, the test boundary mode includes a full traversal mode and a custom mode. The full traversal mode performs a full traversal test within the range of motion controller parameters set in step S1; the custom mode screens the required test points and test ranges through a visual table.

[0065] S3: Start the test;

[0066] like Figure 4 ,5, S4: Compare the current point test data with the standard code, and mark the comparison result at the corresponding position in the real-time monitoring window interface.

[0067] When the device is testing, according to the storage location of the standard code, if the code is read correctly, a green light will be displayed at the corresponding position, which is convenient for real-time understanding of the test status of each barcode. You can also know the decoding status of the device at the current location in real time.

[0068] In step S4, the real-time monitoring window interface displays the real-time motion position and real-time test results, where the horizontal direction is the depth of field distance and the vertical direction is the height from the center of the barcode.

[0069] S5: According to the comparison result of step S4, the bit error rate of each point on the YZ plane is counted according to the position of the test point.

[0070] There are two statistical schemes adopted in step S5, and the corresponding statistical scheme can be selected according to needs.

[0071] like Figure 6 As shown, in this embodiment, a solution of calculating the bit error and leakage rate according to the test point position is adopted, and step S5 is specifically as follows:

[0072] S51: Compare the barcode obtained by the test device with the standard barcode, if they are equal, record it as a correct code; if they are not equal, record it as an error code; when the test device completes the movement, if the code reading information is missing compared with the standard barcode, record it as a missing code;

[0073] S52: According to the result of S51, the accuracy, bit error rate and bit leakage rate of all test points on the YZ plane are calculated respectively.

[0074] like Figure 7 As shown, when the scheme of counting the number of erroneous and missing codes of each barcode at each test point according to the standard barcode information is selected, step S5 is specifically as follows:

[0075] S51: when the X-axis moves leftward / rightward, the index set corresponding to the code word read by the test device is recorded;

[0076] S52: when the X-axis moves leftward / rightward, a set of unmatched standard codeword indexes is obtained;

[0077] S53: At each test point, the barcodes corresponding to the set of unmatched standard codeword indexes are counted respectively. When the test of the point is completed, the number of error and omission codes and the error and omission code rate of each barcode at the position can be obtained.

[0078] Since the test equipment also has the risk of missing or erroneous codes when reading the position code information, the missing or erroneous code rate method based on the standard barcode information cannot separately count the missing or erroneous code rates and needs to be combined for statistics.

[0079] S6: Screening the bit error and leakage rates of each point obtained in step S5, and generating a visual data graph according to the screening results.

[0080] like Figure 8 As shown, through the "Open Data Analysis Tool" in the main interface, import the statistical file generated by the test in step 5, as shown in Fig. 9 The visual data graph shown.

[0081] The specific steps of S6 are:

[0082] S61: Obtain the bit error rate of all test points according to step S5, and extract the maximum and minimum values ​​of the bit error rate that meets the standard at each depth of field;

[0083] S62: adding half of the barcode length to the maximum value and subtracting half of the barcode length from the minimum value to obtain the maximum window value and the minimum window value of the current depth of field;

[0084] S63: Record the points between the maximum window value and the minimum window value that do not meet the standard error rate, and mark them in the visual data graph finally generated.

[0085] The three-axis automated testing method and system described in the present invention can select the test mode and test range according to the needs, thus shortening the test time in a small range. By displaying the real-time test position and generating a visual data graph, it is convenient to observe the test process and results intuitively. By setting various statistical schemes such as test point position statistics and standard barcode information statistics, the integrity of the test data and the comprehensiveness of the data analysis are ensured.
