[0025] In one embodiment, a multi-PCBA board testing method based on a Bluetooth test system is proposed, referring to Figure 1 The Bluetooth test system includes: a control device, a USB to serial port board, a Bluetooth comprehensive tester and a plurality of shielding boxes; the control device is electrically connected to the USB to serial port board based on a USB interface; a plurality of control serial ports of the USB to serial port board are electrically connected to the control serial ports of the main control chip in each shielding box; a plurality of test serial ports of the USB to serial port board are electrically connected to the test serial ports in each shielding box; a plurality of RF ports of the Bluetooth comprehensive tester are electrically connected to the RF switch in each shielding box;

[0026] In each shielding box, an analog switch and multiple PCBA test positions are also provided. Each PCBA test position is electrically connected to the test serial port via the analog switch, and the PCBA test position is used to access the PCBA board; the main control chip is electrically connected to the RF switch based on the communication serial port; the IO port of the main control chip is electrically connected to the analog switch to control the connection between each PCBA test position and the test serial port and the RF switch through the analog switch.

[0027] In this embodiment, the control device is responsible for managing the control and data transmission of the entire test system, and communicates with the Bluetooth comprehensive tester and the USB to serial port board. The control device is electrically connected to the USB to serial port board via a USB interface (such as a Type-C interface); the communication connection established between the control device and the Bluetooth comprehensive tester can be a wired communication connection or a wireless communication connection, preferably a wireless communication connection (such as an Ethernet connection).

[0028] The USB to serial port board serves as a bridge between the control device and each shielding box. It has a built-in multi-channel USB to UART chip and is responsible for transmitting control signals and test data. The USB to serial port board has multiple control serial ports and test serial ports, which are used to send and receive control signals and test data respectively.

[0029] The multiple control serial ports of the USB to serial port board are respectively connected to the control serial ports of the main control chip in each shielding box; the multiple test serial ports of the USB to serial port board are respectively connected to the test serial ports in each shielding box. A control serial port and a test serial port provided by the USB to serial port board are considered as a serial port group, and the same serial port group is electrically connected to the same shielding box. The number of serial port groups that the USB to serial port board can provide corresponds to the number of shielding boxes.

[0030] The Bluetooth comprehensive tester is used to send and receive Bluetooth signals and perform RF testing. The Bluetooth comprehensive tester has multiple RF ports, which are connected to the RF switches in each shielding box.

[0031] Multiple shielding boxes are used to provide an isolated environment to ensure that each PCBA board connected to the box is not interfered by the outside world during the test. Each shielding box contains a main control chip, RF switch, analog switch and multiple PCBA test positions.

[0032] The main control chip is integrated in the shielding box and is responsible for controlling the test process of each PCBA board connected to the shielding box. The main control chip is electrically connected to the analog switch through its IO port to control the connection between each PCBA test position and the test serial port and RF switch through the analog switch.

[0033] The RF switch is used to switch Bluetooth signals between PCBA boards to achieve rotation testing.

[0034] The analog switch is used to control the connection between each PCBA test position and the test serial port and the RF switch, so that the PCBA test position can be electrically connected to the test serial port through the analog switch, and electrically connected to the RF switch through the analog switch and the main control chip.

[0035] The PCBA test station is provided with corresponding wiring interfaces for connecting to the PCBA board to be tested.

[0036] Based on the above Bluetooth test system, refer to Figure 2 , the multi-PCBA board testing method based on the Bluetooth test system includes:

[0037] Step S10: When the Bluetooth test system is running, the control device sends a control instruction to the multiple shielding boxes through the control serial port of the USB-to-serial port interface board to select a PCBA board in each shielding box so that the PCBA board is connected to the test serial port and the RF switch;

[0038] Step S20, the control device sends test data to the selected PCBA boards in each shielding box through the test serial port of the USB to serial port interface board, so that the PCBA boards perform communication test with the Bluetooth comprehensive tester through the RF switch; wherein the Bluetooth comprehensive tester feeds back corresponding test results to the control device based on the communication results;

[0039] Step S30: After receiving the test results corresponding to each PCBA board, the control device selects the next PCBA board in each shielding box, and returns to execute the control device to send test data to the selected PCBA board in each shielding box through the test serial port of the USB-to-serial port interface board, so that the PCBA board performs communication test with the Bluetooth comprehensive tester through the RF switch, until all PCBA board tests are completed.

[0040] As described in step S10, before the Bluetooth test system is officially operated, the control device may first perform self-test and initialization.

[0041] The USB interface (such as Type-C interface) of the control device is connected to the USB to serial port board through a USB cable. The USB to serial port board receives the connection request of the control device and completes the hardware initialization. The built-in multi-channel USB to UART chip starts working and is ready to receive and send control signals and test data.

[0042] The control device notifies the Bluetooth comprehensive tester to start and complete self-test, and prepare for RF testing. Multiple RF ports of the Bluetooth comprehensive tester are ready to be connected to the RF switches in each shielding box.

[0043] When the system is officially running, the control device sends control instructions to multiple shielding boxes through the control serial port of the USB to serial port interface board. The content of the control instruction includes selecting a PCBA board in each shielding box to connect it to the test serial port and the RF switch.

[0044] After receiving the command from the control device, the USB to serial port board forwards the command to the main control chip in each shielding box through its multiple control serial ports. Each control serial port corresponds to a shielding box, ensuring that the command reaches the target shielding box accurately.

[0045] The main control chip in each shielding box receives the command from the USB to serial port interface board through its control serial port. The main control chip parses the command and controls the analog switch through its IO port to select the corresponding PCBA test bit (for example, in the first round of testing, the first PCBA test bit in each shielding box is generally selected). The analog switch connects the specific PCBA test bit to the test serial port and the RF switch according to the control signal of the main control chip.

[0046] The enabled PCBA board is successfully connected to the test serial port and RF switch. The test serial port and RF switch are ready to receive signals from the control device and Bluetooth comprehensive tester.

[0047] As described in step S20, after the control device confirms the PCBA board is enabled in step S10, it prepares test data. The test data may include test parameters of the Bluetooth signal (such as signal strength, frequency, modulation mode, etc.) and test instructions (such as sending signals, receiving responses, etc.).

[0048] The control device sends the test data to the selected PCBA board in each shielding box through the test serial port of the USB to serial port interface board. After receiving the data from the control device, the USB to serial port interface board forwards the data to the test serial port in the corresponding shielding box through its multiple test serial ports.

[0049] The PCBA board in each shielding box receives data from the USB-to-serial board through its test serial port. The PCBA board parses the test data, identifies the test parameters and instructions, and then prepares for communication testing based on the received test instructions. For example, the PCBA board can adjust the transmission strength, frequency or modulation mode of its Bluetooth signal to match the test parameters.

[0050] Among them, the selected PCBA board sends a Bluetooth signal to the Bluetooth comprehensive tester through the RF switch according to the test instruction, and the Bluetooth comprehensive tester receives the Bluetooth signal and feeds back the result of the PCBA board sending the Bluetooth signal to the control device.

[0051] After receiving the Bluetooth signal from the PCBA board, the Bluetooth comprehensive tester can directly analyze and process it to generate the corresponding test results; that is, the Bluetooth comprehensive tester analyzes the received Bluetooth signal to detect the quality and performance of the signal. For example, the Bluetooth comprehensive tester may detect the signal strength, frequency stability, modulation error, etc. Among them, the Bluetooth comprehensive tester generates detailed test results based on the received Bluetooth signal, and the test results include the signal transmission quality of the PCBA board (such as signal strength, frequency offset, modulation error, etc.).

[0052] Alternatively, the Bluetooth comprehensive tester can first feed back a response signal to the PCBA board, and then repeatedly perform multiple rounds of Bluetooth communication with each other. After multiple rounds of communication, the Bluetooth comprehensive tester generates the final test results based on the data generated during the communication process. The test results include the detailed performance of each round of communication and communication quality indicators (such as bit error rate, transmission delay, etc.).

[0053] The Bluetooth comprehensive tester feeds back the final test results to the control device through the communication connection. After receiving the final feedback from the Bluetooth comprehensive tester, the control device records the final test results of each PCBA board.

[0054] As described in step S30, after the control device receives the test results corresponding to each currently selected PCBA board, it sends a new control instruction to each shielding box through the control serial port of the USB to serial port interface board. After the control instruction selects the next PCBA board in each shielding box and connects it to the test serial port and the RF switch, the control device returns to step S20, sends test data to the selected PCBA board in each shielding box through the test serial port of the USB to serial port interface board, and continues the communication test.

[0055] The Bluetooth comprehensive tester continues to receive and analyze the test results and feeds them back to the control device.

[0056] The control device repeats the above steps until all PCBA board tests are completed. After the test is completed, the control device generates a complete test report, recording the test results and performance indicators of all PCBA boards.

[0057] In this way, the Bluetooth test system adopts parallel testing between multiple shielding boxes. The Bluetooth comprehensive tester can send corresponding test data to each shielding box in parallel through multiple RF ports. Inside each shielding box, the main control chip controls the test of each PCBA test position in turn through analog switches.

[0058] After the current round of PCBA board testing in each shielding box is completed, the main control chip switches to the next PCBA test position through the analog switch, and selects the connection between the second PCBA test position and the test serial port and the RF switch. Repeat the above Bluetooth signal test and data transmission steps. The main control chip continues to select each PCBA test position in turn through the analog switch, and performs tests in turn until all PCBA test positions have completed the test.

[0059] The system ensures the accuracy and reliability of the test through intelligent control devices, flexible signal switching mechanism and isolated test environment. This design not only optimizes resource utilization, but also enhances the flexibility and scalability of the system, which can meet the needs of high-efficiency Bluetooth testing in large-scale production environments.

[0060] In one embodiment, by introducing multiple shielding boxes, intelligent control equipment and a reasonable signal switching mechanism, parallel testing between multiple shielding boxes and rotation testing of PCBA boards in each shielding box are achieved, which not only improves the efficiency of Bluetooth testing on PCBA boards, but also optimizes resource utilization, can meet the needs of high-efficiency Bluetooth testing in large-scale production environments, and improve overall production efficiency and product quality.

[0061] In one embodiment, based on the above embodiment, the multi-PCBA board testing method based on the Bluetooth testing system further includes:

[0062] The control device determines whether the PCBA board passes the Bluetooth test based on the test results and preset conditions;

[0063] If the PCBA board fails the Bluetooth test, it will be marked as NG and the corresponding prompt message will be output.

[0064] In this embodiment, after the control device receives the test result of the PCBA board, it compares the test result with the preset condition to determine whether the PCBA board meets the quality requirements of Bluetooth communication.

[0065] When the control device determines whether the PCBA board passes the Bluetooth test, it refers to at least one of the following preset conditions:

[0066] Bluetooth signal strength: whether the Bluetooth signal strength in the test result meets the preset strength, where the preset strength can be a range value, such as -50dBm to -80dBm;

[0067] Bluetooth transmission rate: whether the Bluetooth transmission rate in the test result meets the preset rate, where the preset rate can be a specific value, such as greater than or equal to 1Mbps;

[0068] Bit error rate of Bluetooth transmission: whether the bit error rate in the test result is within a specified range, where the specified range can be a percentage, such as less than 0.1%;

[0069] Bluetooth power consumption: whether the Bluetooth power consumption in the test result is within the qualified range, where the qualified range can be a numerical range, for example, less than 10mA;

[0070] Stability of Bluetooth connection: Whether the Bluetooth connection in the test result meets the preset stability requirements, where the stability requirements can be measured by the connection success rate and delay time of multiple rounds of communication tests.

[0071] Optionally, if the test result of the PCBA board does not meet the preset conditions, that is, fails the Bluetooth test, the control device marks the PCBA board as an NG product. The control device outputs corresponding prompt information, such as displaying a "test failed" or "NG" logo on the control interface, and records relevant test data and fault information.

[0072] If the PCBA board passes all the preset test conditions, it is marked as OK, indicating that it has passed the Bluetooth test.

[0073] Optionally, for PCBA boards marked as NG products, the control system can take further processing measures: generate a detailed NG product report to record the specific reasons and fault points for test failure; and / or upload the NG product information to the production management system for subsequent repair or scrapping.

[0074] The test accuracy and consistency are improved through automated test result judgment and NG product marking. Detailed NG product reports and prompt information help quickly locate the fault point and improve maintenance efficiency. Integrating test results and NG product information into the production management system facilitates quality traceability and data analysis.

[0075] This embodiment further improves the intelligence level and production efficiency of the Bluetooth test system by introducing automated test result judgment and NG product marking functions, ensuring that each PCBA board can be accurately tested and quality assured. The detailed setting of preset conditions makes the test process more standardized and normalized, thereby improving overall production efficiency and product quality.

[0076] In one embodiment, based on the above embodiment, the multi-PCBA board testing method based on the Bluetooth testing system further includes:

[0077] After all PCBA boards are tested, the control device outputs a prompt message for replacing the next batch of PCBA boards.

[0078] In this embodiment, when all PCBA boards of the same batch are tested, the control device outputs a prompt message for replacing the next batch of PCBA boards, reminding the operator to prepare the next batch of PCBA boards for testing.

[0079] Optionally, the USB-to-serial port board has four control serial ports and four test serial ports, corresponding to four shielding boxes, and each shielding box is provided with five PCBA test positions.

[0080] In this way, the number of PCBA boards that can be connected in a batch is 20. When the 20 PCBA boards in the same batch are tested, the control device outputs a prompt message for replacing the next batch of PCBA boards.

[0081] In this way, after the test is completed, it will automatically prompt to replace the next batch of PCBA boards, making the entire testing process smoother and more efficient.

[0082] In one embodiment, based on the above embodiment, referring to Figure 3 The power supply end of the main control chip is responsible for connecting to the power supply; the main control chip is also electrically connected to the power supply end of each PCBA test position through the power output control module;

[0083] The control instructions output by the control device are also used to enable the main control chip to control the power supply of the selected PCBA board to be turned on, and to cut off the power supply of the unselected PCBA board.

[0084] In this embodiment, the power supply terminal of the main control chip is responsible for connecting to the power supply and is connected to an external power adapter or a battery module through a power line.

[0085] The power output control module is electrically connected to the main control chip and further connected to the power supply terminal of each PCBA test position. According to the number and requirements of each PCBA test position, the power output control module can provide multiple independent power outputs.

[0086] The main control chip communicates with the power output control module through the IO port to control it to enable the corresponding power output and ensure that only the currently enabled PCBA test position obtains power supply.

[0087] Optionally, when the control device decides to test a specific PCBA board, it will send corresponding control instructions to the main control chip through the control serial port of the USB to serial port interface board. After receiving these instructions, the main control chip connects the power supply to the selected PCBA test position through the power output control module. The power output control module will turn on the power supply according to the instructions of the main control chip, provide the required power for the selected PCBA board, and ensure that it can work normally and be tested.

[0088] For the unselected PCBA boards, the main control chip promptly cuts off the power connection of the unselected PCBA boards through the power output control module to avoid unnecessary power consumption and potential electromagnetic interference.

[0089] By introducing the power supply terminal and power output control module of the main control chip, the Bluetooth test system of multiple PCBA boards realizes intelligent power management of each PCBA test position. This design not only ensures the stable distribution and safety protection of power, but also realizes seamless switching between multiple PCBA test positions through intelligent control, improving test efficiency and system reliability. While ensuring test quality and working stability, the power management part optimizes resource utilization, enhances the flexibility and scalability of the system, and can meet the needs of high-efficiency Bluetooth testing in large-scale production environments.

[0090] In one embodiment, based on the above embodiment, the control serial port, the test serial port, the IO port, and the communication serial port are all configured with corresponding receiving / sending signal indicator lights;

[0091] According to the receiving / transmitting status of the control serial port, the test serial port, the IO port, and the communication serial port, the on / off of the receiving / transmitting signal indicator light is controlled.

[0092] In this embodiment, in order to improve the visualization and monitoring capabilities of the system, the control serial port, the test serial port, the IO port and the communication serial port are all equipped with corresponding receiving / sending signal indicator lights. According to the receiving / sending status of each serial port, the on / off of the receiving / sending signal indicator lights is controlled.

[0093] The receiving / sending signal indicator light can be used to display the signal receiving / sending status of the control serial port, the test serial port, the IO port, and the communication serial port, helping the operator understand the operation of the system. Through the receiving / sending signal indicator light, you can intuitively see whether the data is transmitted normally, which helps to discover and solve communication problems in a timely manner.

[0094] By configuring corresponding receiving / transmitting signal indicators on the control serial port, test serial port, IO port and communication serial port, the Bluetooth test system for multiple PCBA boards can achieve real-time monitoring of signal status and fault diagnosis. The signal indicator light not only improves the maintainability and operation convenience of the system, but also enhances the reliability of the system. This design not only optimizes the overall operating efficiency of the system, but also simplifies the troubleshooting process, which can meet the needs of high-efficiency Bluetooth testing in large-scale production environments.

[0095] In one embodiment, based on the above embodiment, the multi-PCBA board testing method based on the Bluetooth testing system further includes:

[0096] Using GPT technology, analyze the test results of each PCBA board and generate corresponding test reports.

[0097] In this embodiment, after completing the test of each PCBA board, the Bluetooth comprehensive tester feeds back the test results to the control device. These test results include but are not limited to: signal quality, connection stability, transmission rate, power consumption and other parameters. The control device organizes these raw test data into a structured form to form a test data set for subsequent analysis and processing.

[0098] Before inputting into the GPT model, the test data can be preprocessed, such as standardization, outlier detection, data encoding, etc., to ensure that the data format is suitable for model processing.

[0099] The preprocessed test data is passed as input to the GPT model. The GPT model analyzes the data based on the patterns learned during training and generates a detailed description of the test results.

[0100] The GPT model not only identifies anomalies or failure cases in the test, but also provides possible causes of failure and suggested solutions. For example, if the signal quality of a PCBA board does not meet the standard, GPT can analyze whether it is an antenna design problem, insufficient power or environmental interference.

[0101] The test report template is designed in advance, including the title, test object, test date, test result overview, detailed test data, analysis conclusion, fault diagnosis and improvement suggestions. Based on the preprocessed data and the analysis results of the GPT model, the system automatically fills in the report template and generates a structured test report. Each PCBA board can generate an independent test report.

[0102] The generated test report can be archived in the system for subsequent review and analysis. At the same time, the report can be distributed to relevant personnel such as engineers, quality control departments, etc. through email, system notification, etc.

[0103] In this way, the time and effort of manually writing test reports are greatly reduced, and work efficiency is improved. Through GPT technology, the analysis of test results is more accurate and comprehensive, reducing human errors and omissions. The ability to quickly generate reports after the test is completed provides a guarantee for timely discovery and resolution of problems in production. The GPT model can learn from large amounts of data, provide intelligent fault diagnosis and optimization suggestions, and help continuously improve product quality.

[0104] For example, if a PCBA board has an abnormally high power consumption problem during testing, the GPT model may generate the following analysis:

[0105] Test result overview: The overall power consumption of the PCBA board in the test was twice the expected value, exceeding the threshold specified by the system;

[0106] Detailed test data: including power consumption values ​​under different working modes;

[0107] Analysis conclusion: Preliminary judgment is that the power management circuit may be improperly designed or a component may be abnormal;

[0108] Fault diagnosis: It is recommended to check the power management chip and its peripheral circuits, or replace the suspected faulty components;

[0109] Improvement suggestion: Optimize the design of the power management circuit to ensure that its power consumption remains at a normal level in various operating modes.

[0110] In this way, test report generation based on GPT technology not only improves the efficiency of the testing process, but also provides a scientific basis and intelligent support for improving product quality.

[0111] In addition, a control device is also provided in an embodiment of the present application. The internal architecture of the control device can be as follows: Figure 4As shown, it includes a processor, a memory, a communication interface and an input interface connected by a system bus. The processor is used to provide computing and control capabilities. The memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database is used to store data called by the computer program. The communication interface is used to communicate data with an external terminal. The input interface is used to receive a signal input by an external device. When the computer program is executed by the processor, a multi-PCBA board testing method based on a Bluetooth test system as described in the above embodiment is implemented.

[0112] Those skilled in the art will understand that Figure 4 The structure shown in the figure is only a block diagram of a part of the structure related to the present application scheme, and does not constitute a limitation on the control device to which the present application scheme is applied.
