Description

Technical Field

[0001] This invention relates to the field of testing technology for barcode recognition modules, specifically, to a testing method for barcode recognition modules, a testing device for barcode recognition modules using the same testing method, and a computer-readable storage medium using the same testing method. Background Technology

[0002] With the rapid development of smart education and consumer electronics, barcode recognition modules are widely used in products such as reading pens, smart learning tablets, and AR interactive devices. As a core component for accurate reading and information interaction, the performance stability and reliability of barcode recognition modules directly determine the user experience of end products. Market demand for these modules is not only reflected in their core function of accurate recognition, but also in their stringent requirements for circuit operation safety. If there are faults such as short circuits, poor soldering, or abnormal component parameters in the internal circuit of the module, it will directly cause the operating current to deviate from the normal range. This can lead to a sharp drop in the battery life of the terminal device, or even overheating and burnout of the circuit due to prolonged abnormal current, and may even cause safety hazards. However, existing testing methods generally focus only on the recognition function of the barcode reader module. They determine the module's qualification by manually triggering a few reading operations and observing whether the barcode value can be correctly recognized. This type of testing completely ignores the detection of the module's operating current. Abnormal operating current is a direct indication of faults such as short circuits, poor soldering, and component failures within the module's internal circuitry. After such modules are installed in terminal devices, they may initially exhibit normal recognition capabilities, but with prolonged use, internal circuit faults will gradually worsen. This not only shortens the device's battery life due to abnormal current but may also cause overheating, burn out the module, or even damage the terminal device, resulting in property loss and, in severe cases, safety risks. Therefore, a more optimized testing method for QR code recognition modules needs to be considered. Summary of the Invention

[0003] The primary objective of this invention is to provide a testing method for barcode recognition modules that can simultaneously detect both functional and circuit faults in the barcode recognition module, thereby improving testing efficiency.

[0004] The second objective of this invention is to provide a testing device for a barcode recognition module that can simultaneously detect both the functionality and circuit faults of the barcode recognition module, thereby improving testing efficiency.

[0005] A third objective of this invention is to provide a computer-readable storage medium that can simultaneously detect the functionality and circuit faults of a barcode scanning module, thereby improving testing efficiency.

[0006] To achieve the aforementioned first objective, the present invention provides a testing method for a barcode recognition module, comprising: activating a barcode recognition module testing device; upon receiving a test command, acquiring a preset number of barcode values ​​obtained by the barcode recognition module under test for recognizing the same test barcode through a test interface, and acquiring the current value of the barcode recognition module under test during testing from the power supply circuit; confirming the recognition rate based on the preset number of barcode values; and confirming the barcode recognition module under test as qualified when the recognition rate is greater than a preset value and the current value is within a preset current value range.

[0007] As can be seen from the above scheme, in the testing method of the barcode recognition module of the present invention, by simultaneously acquiring the recognition rate and the current value of the barcode recognition module under test during testing, the recognition function of the barcode recognition module under test is tested by the recognition rate, and the internal circuit of the barcode recognition module under test is detected by the current value, thereby realizing the simultaneous detection of the function and circuit faults of the barcode recognition module, improving testing efficiency, and ensuring the yield of the barcode recognition module under test.

[0008] In a further scheme, the step of confirming the recognition rate based on a preset number of reading code values ​​includes: counting the number of identical reading code values ​​to obtain the number of reading codes corresponding to the reading code value with the most occurrences; and obtaining the recognition rate based on the ratio of the number of reading codes to the preset number.

[0009] Therefore, it can be seen that the recognition rate is calculated by counting the number of reading codes with the highest proportion among the preset number of reading code values ​​recognized by the same test code, rather than by counting correct or incorrect in the traditional way. This can filter out sporadic misidentifications caused by momentary interference and accurately reflect the module's stable recognition ability for the same code value, thereby reducing the probability of misjudgment.

[0010] In a further proposed solution, after counting the number of identical reading code values, the solution also includes: ranking all reading code values ​​from most to least numerous, and displaying the top three reading code values.

[0011] Therefore, by ranking the reading code values ​​and displaying the top three reading code values, the high-frequency code values ​​that appear during the module recognition process can be presented intuitively. This makes it easier for testers to quickly locate the type of recognition deviation and provides direct data support for subsequent algorithm optimization or hardware debugging of the recognition module.

[0012] In a further solution, the step of obtaining a preset number of reading code values ​​obtained by the reading code recognition module under test for the same test point through the test interface includes: controlling the reading code recognition module under test to obtain a reading code value once every first preset time interval.

[0013] Therefore, by periodically collecting a preset number of reading code values ​​of the same test code at a first preset time interval, the continuous working state of the module in actual use can be simulated, avoiding the one-sidedness of the results caused by a single instantaneous collection, and accurately reflecting the recognition stability of the module under continuous operation.

[0014] In a further solution, before obtaining the preset number of code values ​​obtained by the code recognition module under test for the same test point through the test interface, the solution also includes: obtaining the software version number of the code recognition module under test and confirming that the software version number is correct.

[0015] Therefore, before collecting and identifying data, it is necessary to confirm whether the software version of the module under test is the target version, so as to eliminate identification anomalies caused by software version mismatch, missing firmware or version error from the source and avoid misjudgment.

[0016] In a further solution, after obtaining the software version number of the code reading and recognition module to be tested, the solution also includes: if the software version number is confirmed to be incorrect, then the code reading and recognition module to be tested is upgraded.

[0017] Therefore, triggering an upgrade operation when a version error occurs ensures that all code recognition modules under test participate in subsequent testing under a unified target software version. This eliminates recognition anomalies caused by software version mismatch or outdated firmware from the source, guarantees the consistency of test benchmarks and the comparability of test results, and reduces the cost of invalid and duplicate tests.

[0018] In a further embodiment, the step of obtaining the current value of the code recognition module under test from the power supply circuit during testing includes: during the testing process of the code recognition module under test, obtaining the test current value of the code recognition module under test for a preset number of times, and calculating the average value of the test current value to obtain the current value.

[0019] Therefore, by collecting current values ​​multiple times and calculating the average value during the test, the influence of instantaneous current fluctuations can be effectively offset, accurately reflecting the real current during the module testing phase. This allows for the determination of whether there are hidden faults such as short circuits, leakage, or abnormal components in the internal circuit.

[0020] In a further embodiment, the barcode recognition module testing device also includes a test status indication circuit, which is electrically connected to the main control circuit. After receiving the test command, it also includes: obtaining the serial number of the barcode recognition module under test, and binding and storing the test data of the barcode recognition module under test with the serial number.

[0021] Therefore, after receiving the test command, collecting the serial number of the module under test and binding and storing the serial number with the test data to form a complete test file can facilitate subsequent product quality traceability, improve the precision of quality control and the efficiency of quality problem investigation.

[0022] To achieve the second objective of this invention, this invention provides a test device for a barcode recognition module, including a processor and a memory. The memory stores a computer program, and when the computer program is executed by the processor, it implements the steps of the above-described barcode recognition module test method.

[0023] To achieve the third objective of the present invention, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a controller, implements the steps of the above-described dot-read code recognition module testing method.

[0026] Figure 3 This is a flowchart illustrating the steps of confirming the recognition rate based on a preset number of dot-read code values ​​in an embodiment of the dot-read code recognition module testing method of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0028] Example of a test method for a barcode recognition module: The barcode recognition module testing method of the present invention is an application program used in the barcode recognition module testing device to control the barcode recognition module testing device to test the barcode recognition module.

[0029] In this embodiment, as Figure 1 As shown, the barcode reader module testing device includes a main control circuit 1, a power supply circuit 2, a test interface 3, a test status indication circuit 4, a communication circuit 5, a button circuit 6, a storage circuit 7, and an extended control interface 8. The power supply circuit 2 provides power to the main control circuit 1, test interface 3, test status indication circuit 4, communication circuit 5, button circuit 6, storage circuit 7, and extended control interface 8. The test interface 3, test status indication circuit 4, communication circuit 5, button circuit 6, storage circuit 7, and extended control interface 8 are all electrically connected to the main control circuit 1. The test interface 3 is used to connect the barcode reader module 9 under test, providing a path for power, control, and data communication.

[0030] The test status indication circuit 4 is used to indicate the test status of the code recognition module 9 under test. The test status indication circuit 4 includes an audio indication circuit (not shown) and an LED indicator circuit (not shown). The audio indication circuit indicates the test status of the code recognition module 9 under test by sound, and the LED indicator circuit indicates the test status of the code recognition module 9 under test by indicator lights of different colors.

[0031] Communication circuit 5 is used to communicate with host computer 10, and can upload test-related information to host computer 10 for display. Communication circuit 5 is connected to host computer 10 via USB interface.

[0032] The button circuit 6 includes test function buttons, image capture function buttons, and upgrade function buttons. Different buttons control the device to perform corresponding functions. For example, pressing the test function button initiates the normal testing process of the code recognition module 9; pressing the image capture function button initiates the image capture process of the code recognition module 9; and pressing the upgrade function button initiates the upgrade process of the code recognition module 9. These corresponding function buttons simplify control operations.

[0033] In addition, storage circuit 7 is used to store test results, firmware information of the testing device, etc. Extended control interface 8 is used to communicate with other control circuits to achieve automated production.

[0034] like Figure 2 As shown, in this embodiment, the barcode reader module testing method first executes step S1 to start the barcode reader module testing device. When the barcode reader module testing device needs to operate, it can be started by pressing the start button. Starting the barcode reader module testing device first initializes the barcode reader module 9 under test, ensuring normal communication between the main control circuit 1 and the barcode reader module 9 under test.

[0035] After starting the dot-read code recognition module testing device, step S2 is executed to determine whether a test command has been obtained. After starting the dot-read code recognition module testing device, a test command can be sent to the main control circuit 1. The test command can be obtained through the host computer 10 or through the button circuit 6.

[0036] If no test command is received, continue to step S2 for continuous testing. When a test command is received, proceed to step S3 to obtain the software version number of the code recognition module 9 under test. The software version number of the code recognition module 9 under test can be displayed on the host computer 10 for the user to verify the software version.

[0037] After obtaining the software version number, proceed to step S4 to determine if the software version number is correct. Before collecting identification data, first confirm whether the software version of the module under test is the target version. This eliminates identification anomalies caused by software version mismatch, missing firmware, or version errors from the source, avoiding misjudgments. By comparing the obtained software version number with the target software version number, its correctness can be determined.

[0038] If the software version number is confirmed to be incorrect, step S5 is executed to upgrade the code reader recognition module 9 under test. Triggering the upgrade operation when a software version error occurs upgrades the software version number of the code reader recognition module 9 under test to the target software version number. This ensures that all code reader recognition modules 9 under test participate in subsequent testing under a unified target software version, eliminating recognition anomalies caused by software version mismatch or outdated firmware at the source. This guarantees the consistency of the test benchmark and the comparability of test results, reducing the cost of invalid and repetitive testing. During the upgrade operation of the code reader recognition module 9 under test, the module is first initialized. Then, the upgrade package file in the storage circuit 7 is read, and the upgrade file is written to the code reader recognition module 9 under test via the upgrade protocol. After the upgrade is completed, the code reader recognition module 9 under test is shut down and restarted, and the current software version number of the code reader recognition module 9 is read and displayed on the host computer 10 for user verification.

[0039] If the software version number is confirmed to be correct, or after upgrading the code recognition module 9 under test, proceed to step S6. Obtain a preset number of code reading values ​​obtained by the code recognition module 9 under test for the same test point through test interface 3, and obtain the current value of the code recognition module 9 under test during testing from power circuit 2. The preset number can be pre-set based on experimental data; for example, the preset number can be 100. Since the recognition function of the code recognition module 9 under test and the current value during testing are the criteria for evaluating its pass / fail status, it is necessary to obtain the preset number of code reading values ​​and current values ​​obtained by the code recognition module 9 under test for the same test point during testing.

[0040] In this embodiment, the step of obtaining a preset number of reading code values ​​obtained by the test reading code recognition module 9 for the same test reading code through the test interface 3 includes: controlling the test reading code recognition module 9 to acquire a reading code value once every first preset time interval. The first preset time interval can be preset based on experimental data, for example, 25ms. By periodically acquiring a preset number of reading code values ​​for the same test code at first preset time intervals, the continuous working state of the module in actual use can be simulated, avoiding the bias of results caused by single instantaneous acquisition, and accurately reflecting the recognition stability of the module under continuous operation.

[0041] In this embodiment, the step of obtaining the current value of the code recognition module 9 under test from the power supply circuit 2 during testing includes: acquiring the test current value of the code recognition module 9 under test a preset number of times during the testing process, and calculating the average value of the test current value to obtain the current value. The preset number of times can be pre-set based on experimental data, for example, 5 times. Multiple acquisitions of current values ​​and calculation of the average value during the testing process can effectively offset the influence of instantaneous current fluctuations, accurately reflect the true current during the module testing phase, and thus determine whether there are hidden faults such as short circuits, leakage, or component abnormalities in the internal circuit.

[0042] After obtaining a preset number of reading code values ​​and current values, step S7 is executed to confirm the recognition rate based on the preset number of reading code values. The recognition rate can confirm the recognition function of the reading code recognition module 9 under test; therefore, it is necessary to obtain the recognition rate based on the detected reading code values.

[0043] In this embodiment, see Figure 3 When confirming the recognition rate based on a preset number of reading code values, step S11 is first executed to count the number of identical reading code values ​​and obtain the number of reading codes corresponding to the reading code value with the largest number of occurrences. In order to avoid misjudgment caused by counting the recognition rate based on the traditional correct or incorrect criteria, the number of reading codes corresponding to the reading code value with the largest number of occurrences is obtained by counting the number of identical reading code values.

[0044] After obtaining the number of read-codes corresponding to the most frequent read-code value, step S12 is executed to obtain the recognition rate based on the ratio of the number of read-codes to a preset number. The read-code value with the most frequent count is the actual read-code value corresponding to the test read-code; therefore, the proportion of the most frequent read-code values ​​can be used as the recognition rate. By calculating the recognition rate by statistically analyzing the number of read-codes with the highest percentage among the preset number of read-code values ​​recognized for the same test code, sporadic misidentifications caused by momentary interference can be filtered out, and the module's stable recognition capability for the same code value can be accurately reflected, thereby reducing the probability of misjudgment.

[0045] Furthermore, in this embodiment, after counting the number of identical reading code values, the method further includes: ranking all reading code values ​​from most to least numerous, and displaying the top three reading code values. By ranking the reading code values ​​and displaying the top three, the high-frequency code values ​​that appear during the module recognition process can be intuitively presented, making it easier for testers to quickly locate the type of recognition deviation and providing direct data support for subsequent algorithm optimization or hardware debugging of the recognition module.

[0046] After confirming the recognition rate, proceed to step S8 to determine whether the recognition rate is greater than a preset value and whether the current value is within a preset current value range. The preset value and preset current value range can be preset based on experimental data; for example, a preset value of 90%.

[0047] When the recognition rate is greater than the preset value and the current value is within the preset current value range, step S9 is executed to confirm that the code recognition module 9 under test is qualified. A recognition rate greater than the preset value indicates that the recognition function of the code recognition module 9 under test is normal. A current value within the preset current value range during testing indicates that the internal circuitry of the code recognition module 9 under test is normal. Therefore, the code recognition module 9 under test can be confirmed as qualified.

[0048] If the recognition rate is not greater than the preset value and the current value is not within the preset current value range, then step S10 is executed to confirm that the code reading and recognition module 9 under test is unqualified. If the recognition rate is not greater than the preset value and the current value is not within the preset current value range, it means that the recognition rate is less than or equal to the preset value and / or the current value is outside the preset current value range, indicating that at least one of them is abnormal. Therefore, the code reading and recognition module 9 under test is unqualified.

[0049] After confirming whether the code recognition module 9 under test is qualified or unqualified, the main control circuit 1 can control the test status prompt circuit 4 to provide test status prompts. For example, it can announce whether the code recognition module 9 under test is qualified through an audio prompt circuit, or use an LED indicator circuit to indicate whether the code recognition module 9 under test is qualified through different colors. The main control circuit 1 can also send the test results to the host computer 10 for display to the user.

[0050] In this embodiment, after obtaining the test instruction in step S2, the following steps are also performed: obtaining the serial number of the code reading module 9 to be tested, and binding and storing the test data of the code reading module 9 to the serial number. By collecting the serial number of the module to be tested after obtaining the test instruction and binding and storing the serial number with the test data, a complete test file is formed to facilitate subsequent product quality traceability, improve the precision of quality control, and increase the efficiency of quality problem investigation.

[0051] In addition, after the dot code recognition module test device is started, when the user triggers the image capture command through the button circuit 6, the main control circuit 1 controls the dot code recognition module 9 under test to enter the image capture mode, and the host computer 10 can display the image captured by the dot code recognition module 9 under test for association and storage.

[0052] As described above, in the testing method for the barcode recognition module of the present invention, by simultaneously acquiring the recognition rate of the barcode recognition module 9 under test and the current value of the barcode recognition module 9 under test during testing, the recognition function of the barcode recognition module 9 under test is tested by the recognition rate, and the internal circuit of the barcode recognition module 9 under test is detected by the current value, thereby realizing the simultaneous detection of the function and circuit faults of the barcode recognition module, improving testing efficiency, and ensuring the yield of the barcode recognition module.
