[0010] The control device sends test data to the selected PCBA boards in each shielded box through the test serial port of the USB to serial port connector board, enabling the PCBA boards to communicate with the Bluetooth test instrument through the RF switch; the Bluetooth test instrument feeds back the corresponding test results to the control device based on the communication results.

[0011] After receiving the test results corresponding to each PCBA board, the control device selects the next PCBA board in each shielded box and returns to execute the step of sending test data to the selected PCBA board in each shielded box through the test serial port of the USB to serial port connection board, so that the PCBA board can communicate with the Bluetooth comprehensive tester through the RF switcher, until all PCBA boards are tested.

[0012] To achieve the above objectives, this application also provides a control device, which includes: a memory, a processor, and a computer program stored in the memory and executable on the processor. When the computer program is executed by the processor, it implements the steps of the multi-PCBA board testing method based on the Bluetooth testing system described above.

[0014] Each shielded box is equipped with an analog switch and multiple PCBA test positions. Each PCBA test position is electrically connected to the test serial port via the analog switch, and the PCBA test position is used to connect to the PCBA board.

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

[0026] Each shielded enclosure is equipped with an analog switch and multiple PCBA test positions. Each PCBA test position is electrically connected to a test serial port via the analog switch, and the PCBA test position is used to connect to the PCBA board. The main control chip is electrically connected to the RF switch via the communication serial port. The I / O ports of the main control chip are electrically connected to the analog switch to control and select the connection between each PCBA test position and the test serial port and RF switch.

[0027] In this embodiment, the control device is responsible for managing the control and data transmission of the entire test system and communicating with the Bluetooth comprehensive tester and the USB-to-serial interface board. The control device is electrically connected to the USB-to-serial interface 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 or wireless communication connection, preferably a wireless communication connection (such as via Ethernet).

[0028] The USB-to-serial connector board serves as a bridge between the control equipment and the shielded boxes. It incorporates a multi-channel USB-to-UART chip responsible for transmitting control signals and test data. The USB-to-serial connector board has multiple control serial ports and test serial ports, used for sending and receiving control signals and test data, respectively.

[0029] The USB-to-serial adapter board has multiple control serial ports connected to the control serial ports of the main control chip in each shielded box; its multiple test serial ports are also connected to the test serial ports in each shielded box. Each control serial port and test serial port provided by the USB-to-serial adapter board constitutes a serial port group. Serial port groups within the same group are electrically connected to the same shielded box. The number of serial port groups provided by the USB-to-serial adapter board corresponds to the number of shielded boxes.

[0030] The Bluetooth test suite is used to send and receive Bluetooth signals and perform radio frequency (RF) tests. It has multiple RF ports, each connected to an RF switcher in a shielded enclosure.

[0031] Multiple shielded enclosures provide an isolated environment, ensuring that each PCBA board connected within the enclosure is not subject to external interference during testing. Each shielded enclosure contains a main control chip, an RF switch, an analog switch, and multiple PCBA test positions.

[0032] The main control chip is integrated inside the shielded enclosure and is responsible for controlling the testing process of each PCBA board connected within the enclosure. The main control chip is electrically connected to an analog switch via its I / O port, which controls the connection between each PCBA test position and the test serial port and RF switch.

[0033] The radio frequency switcher is used to switch Bluetooth signals between PCBA boards to enable alternating testing.

[0034] Analog switches are used to control the connection between each PCBA test position and the test serial port and RF switch, so that the PCBA test positions can be electrically connected to the test serial port via analog switches, and electrically connected to the RF switch via analog switches and the main control chip.

[0035] The PCBA test position provides corresponding wiring interfaces for connecting the PCBA board to be tested.

[0036] Based on the aforementioned Bluetooth testing system, and referring to Figure 2 The multi-PCBA board testing method based on the Bluetooth testing system includes:

[0037] Step S10: When the Bluetooth test system is running, the control device sends control commands to multiple shielded boxes through the control serial port of the USB to serial port connector to select one PCBA board in each shielded box, so that the PCBA board connects 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 shielded box through the test serial port of the USB to serial port connector board, so that the PCBA boards can communicate with the Bluetooth test instrument through the RF switch; wherein, the Bluetooth test instrument feeds back the 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 shielded box and returns to execute the step of sending test data to the selected PCBA board in each shielded box through the test serial port of the USB to serial port connection board, so that the PCBA board can communicate with the Bluetooth comprehensive tester through the RF switcher, until all PCBA boards are tested.

[0040] As described in step S10, before the Bluetooth test system is officially put into operation, the control device can perform self-test and initialization.

[0041] The control device's USB interface (such as a Type-C interface) is connected to the USB-to-serial adapter board via a USB cable. The USB-to-serial adapter board receives the control device's connection request and completes hardware initialization. The built-in multi-channel USB-to-UART chip then begins operation, ready to receive and send control signals and test data.

[0042] The control device instructs the Bluetooth test suite to start and complete its self-test, preparing for radio frequency (RF) testing. Multiple RF ports of the Bluetooth test suite are ready to connect to the RF switchers in their respective shielded enclosures.

[0043] During system operation, the control device sends control commands to multiple shielded boxes via the control serial port of the USB-to-serial adapter board. These commands select one PCBA board from each shielded box, connecting it to the test serial port and the RF switch.

[0044] After receiving commands from the control device, the USB-to-serial adapter board forwards the commands to the main control chip in each shielded enclosure via its multiple control serial ports. Each control serial port corresponds to one shielded enclosure, ensuring that the commands accurately reach the target shielded enclosure.

[0045] The main control chip in each shielded enclosure receives instructions from the USB-to-serial adapter board via its control serial port. The main control chip parses the instructions and controls the analog switches through its I / O ports to select the corresponding PCBA test positions (e.g., in the first round of testing, the first PCBA test position in each shielded enclosure is usually selected). The analog switches connect the specific PCBA test positions to the test serial port and the RF switch according to the control signals from the main control chip.

[0046] The selected PCBA board has successfully connected to the test serial port and RF switch. The test serial port and RF switch are now ready to receive signals from the control device and Bluetooth test instrument.

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

[0048] The control device sends test data to the selected PCBA boards in each shielded enclosure via the test serial port of the USB-to-serial adapter board. After receiving the data from the control device, the USB-to-serial adapter board forwards the data to the corresponding test serial port in the shielded enclosure through its multiple test serial ports.

[0049] Each selected PCBA board within its shielded enclosure receives data from the USB-to-serial adapter board via its test serial port. The PCBA board parses the test data, identifies the test parameters and commands, and then prepares for communication testing based on the received test commands. For example, the PCBA board can adjust the transmission strength, frequency, or modulation method of its Bluetooth signal to match the test parameters.

[0050] The selected PCBA board sends a Bluetooth signal to the Bluetooth tester via an RF switch according to the test command. The Bluetooth 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 tester can directly analyze and process it to generate corresponding test results. In other words, the Bluetooth tester analyzes the received Bluetooth signal to detect its quality and performance. For example, it may detect signal strength, frequency stability, modulation error, etc. Based on the received Bluetooth signal, the Bluetooth tester generates detailed test results, including the signal transmission quality of the PCBA board (such as signal strength, frequency offset, modulation error, etc.).

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

[0053] The Bluetooth test suite sends the final test results back to the control device via a communication connection. Upon receiving the feedback from the Bluetooth test suite, the control device records the final test results for each PCBA board.

[0054] As described in step S30, after receiving the test results corresponding to each currently selected PCBA board, the control device sends new control commands to each shielded box through the control serial port of the USB-to-serial connector. After the control command selects the next PCBA board in each shielded box and connects it to the test serial port and RF switch, the control device returns to step S20 and sends test data to the selected PCBA boards in each shielded box through the test serial port of the USB-to-serial connector to continue the communication test.

[0055] The Bluetooth test instrument continues to receive and analyze the test results and provide feedback to the control equipment.

[0056] The control equipment repeats the above steps until all PCBA boards have been tested. After testing, the control equipment 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 a parallel testing approach across multiple shielded enclosures. The Bluetooth test instrument can send corresponding test data to each shielded enclosure in parallel through multiple RF ports. Inside each shielded enclosure, the main control chip controls the sequential testing of each PCBA test position via analog switches.

[0058] After completing the testing of the current round of PCBA boards in each shielded enclosure, the main control chip switches to the next PCBA test position via an analog switch, enabling the connection between the second PCBA test position and the test serial port and RF switch. The Bluetooth signal testing and data transmission steps described above are repeated. The main control chip continues to sequentially select each PCBA test position via the analog switch, performing tests in turn, until all PCBA test positions have been tested.

[0059] The system ensures the accuracy and reliability of testing through intelligent control equipment, flexible signal switching mechanisms, and an isolated testing environment. This design not only optimizes resource utilization but also enhances the system's flexibility and scalability, meeting the demands for high-efficiency Bluetooth testing in large-scale production environments.

[0060] In one embodiment, by introducing multiple shielded boxes, intelligent control equipment, and a reasonable signal switching mechanism, parallel testing between multiple shielded boxes and alternating testing of PCBA boards within each shielded box are achieved. This not only improves the efficiency of Bluetooth testing of PCBA boards but also optimizes resource utilization, meeting the demand for high-efficiency Bluetooth testing in large-scale production environments and improving overall production efficiency and product quality.

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

[0062] The control equipment determines whether the PCBA board has passed 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 a corresponding prompt message will be output.

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

[0065] When determining whether a PCBA board has passed the Bluetooth test, the control device refers to at least one of the following preset conditions:

[0066] Bluetooth signal strength: Whether the Bluetooth signal strength in the test results 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 results meets the preset rate, where the preset rate can be a specific value, such as greater than or equal to 1Mbps;

[0068] Bluetooth transmission bit error rate: Whether the bit error rate in the test results is within the 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 results is within the acceptable range. The acceptable range can be a numerical range, such as less than 10mA.

[0070] Bluetooth connection stability: Whether the Bluetooth connection in the test results meets the preset stability requirements. The stability requirements can be measured by the connection success rate and latency time in multiple rounds of communication tests.

[0071] Optionally, if the PCBA board's test results do not meet the preset conditions, i.e., it fails the Bluetooth test, the control device marks the PCBA board as an NG product. The control device outputs corresponding prompts, such as displaying "Test Failed" or an "NG" label on the control interface, and records relevant test data and fault information.

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

[0073] Optionally, for PCBA boards marked as NG (Not Good), the control system can take further action: generate a detailed NG report, recording the specific reasons for the test failure and the fault point; and / or upload the NG information to the production management system for subsequent repair or scrapping.

[0074] The automated testing result evaluation and NG (non-compliant) item marking improve the accuracy and consistency of testing. Detailed NG reports and alerts help quickly locate fault points and improve repair efficiency. Integrating test results and NG information into the production management system facilitates quality traceability and data analysis.

[0075] This embodiment further improves the intelligence and production efficiency of the Bluetooth testing system by introducing automated test result judgment and NG (non-compliant) marking functions, ensuring that each PCBA board receives accurate testing and quality assurance. Detailed preset conditions make the testing process more standardized and regulated, thereby improving overall production efficiency and product quality.

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

[0077] After all PCBA boards have been tested, the control equipment outputs a prompt message to replace the next batch of PCBA boards.

[0078] In this embodiment, once all PCBA boards in the same batch have been tested, the control device outputs a prompt message to replace 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 connector board has four control serial ports and four test serial ports, corresponding to four shielded boxes, and each shielded box has five PCBA test positions.

[0080] In this way, a batch of 20 PCBA boards can be connected. Once all 20 PCBA boards in the same batch have been tested, the control device will output a prompt message to replace the next batch of PCBA boards.

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

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

[0083] The control commands output by the control device are also used to enable the main control chip to control the power supply of the selected PCBA boards and cut off the power supply of the unselected PCBA boards.

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

[0085] The power output control module is electrically connected to the main control chip and further connected to the power supply terminals of each PCBA test station. Depending on the number and requirements of each PCBA test station, 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, controls it to select the corresponding power output, and ensures that only the currently selected PCBA test bit receives power supply.

[0087] Optionally, when the control device decides to test a specific PCBA board, it sends corresponding control commands to the main control chip via the control serial port of the USB-to-serial connector. Upon receiving these commands, the main control chip connects the power supply to the selected PCBA test position via the power output control module. The power output control module, according to the instructions of the main control chip, turns on the power, providing the necessary power to the selected PCBA board to ensure its normal operation and testing.

[0088] For PCBA boards that are not selected, the main control chip uses the power output control module to promptly disconnect the power supply to the unselected PCBA boards to avoid unnecessary power consumption and potential electromagnetic interference.

[0089] By introducing the power supply and power output control module of the main control chip, the Bluetooth test system for multiple PCBA boards achieves intelligent power management for each PCBA test position. This design not only ensures stable power distribution and safety protection, but also enables seamless switching between multiple PCBA test positions through intelligent control, improving test efficiency and system reliability. The power management section optimizes resource utilization while ensuring test quality and operational stability, enhancing system flexibility and scalability, and meeting the demands for high-efficiency Bluetooth testing in large-scale production environments.

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

[0091] The on / off state of the transmit / receive indicator lights is controlled according to the transmit / receive status of the control serial port, the test serial port, the I / O port, and the communication serial port.

[0092] In this embodiment, to improve the system's visualization and monitoring capabilities, the control serial port, test serial port, I / O port, and communication serial port are all equipped with corresponding transmit / receive signal indicator lights. The on / off state of each serial port is controlled by adjusting the indicator lights.

[0093] The transmit / receive indicator lights display the signal transmission and reception status of the control serial port, the test serial port, the I / O port, and the communication serial port, helping operators understand the system's operating status. These indicator lights provide a clear visual indication of whether data is being transmitted normally, facilitating timely detection and resolution of communication problems.

[0094] By configuring corresponding transmit / receive signal indicator lights on the control serial port, test serial port, I / O port, and communication serial port, the Bluetooth test system for multiple PCBA boards achieves real-time monitoring and fault diagnosis of signal status. These indicator lights not only improve system maintainability and ease of operation but also enhance system reliability. This design optimizes the overall system operating efficiency and simplifies the troubleshooting process, meeting the demands for high-efficiency Bluetooth testing in large-scale production environments.

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

[0096] Using GPT technology, the test results of each PCBA board are analyzed, and corresponding test reports are generated.

[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, parameters such as signal quality, connection stability, transmission rate, and power consumption. The control device organizes these raw test data into a structured form, forming a test dataset for subsequent analysis and processing.

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

[0099] The preprocessed test data is fed into the GPT model. The GPT model analyzes the data based on the patterns learned during training and generates detailed descriptions of the test results.

[0100] The GPT model can not only identify anomalies or failures during testing, but also provide possible causes of failure and suggested solutions. For example, if the signal quality of a PCBA board is substandard, GPT can analyze whether it is due to antenna design issues, insufficient power, or environmental interference.

[0101] A pre-designed test report template is provided, including a title, test object, test date, test result overview, detailed test data, analysis conclusions, fault diagnosis, and improvement suggestions. Based on the pre-processed data and the analysis results of the GPT model, the system automatically populates the report template, generating a structured test report. A separate test report can be generated for each PCBA board.

[0102] The generated test reports can be archived in the system for later review and analysis. Simultaneously, the reports can be distributed to relevant personnel, such as engineers and quality control staff, via email, system notifications, etc.

[0103] This significantly reduces the time and effort required for manually writing test reports, improving work efficiency. Through GPT technology, the analysis of test results is more accurate and comprehensive, reducing human error and omissions. Reports can be generated rapidly after testing, ensuring timely identification and resolution of production issues. The GPT model can learn from large amounts of data, providing intelligent fault diagnosis and optimization suggestions, contributing to continuous improvement of product quality.

[0104] For example, suppose a PCBA board exhibits abnormally high power consumption during testing; the GPT model might generate the following analysis:

[0105] Test Results Summary: The total power consumption of this PCBA board during the test was twice the expected value, exceeding the system's specified threshold.

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

[0107] Analysis conclusion: The preliminary judgment is that the problem may be due to improper design of the power management circuit or a malfunction in a certain component;

[0108] Troubleshooting: It is recommended to check the power management chip and its surrounding circuitry, or replace the suspected faulty component.

[0109] Recommendation for improvement: Optimize the design of the power management circuit to ensure that its power consumption remains at a normal level under various operating modes.

[0110] In this way, the generation of test reports 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] Furthermore, this application embodiment also provides a control device, the internal architecture of which can be as follows: Figure 4As shown, the system includes a processor, memory, communication interface, and input interface connected via a system bus. The processor provides computing and control capabilities. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium stores the operating system, computer programs, and a database. The internal memory provides an environment for the operation of the operating system and computer programs stored in the non-volatile storage medium. The database stores data called by the computer programs. The communication interface is used for data communication with external terminals. The input interface is used to receive signals from external devices. When the computer program is executed by the processor, it implements a multi-PCBA board testing method based on a Bluetooth testing system as described in the above embodiment.

[0112] Those skilled in the art will understand that Figure 4 The structure shown is merely a block diagram of a portion of the structure related to the present application and does not constitute a limitation on the control device to which the present application is applied. For example, in some optional embodiments, the control device may further include an output interface (not shown in the figure), and the output interface is also connected to the system bus and used to output corresponding signals to peripherals.

[0113] Optionally, the control device can be a computer device.

[0114] In addition, this application embodiment also provides a Bluetooth testing system, referring to Figure 1 or Figure 3 The Bluetooth testing system includes: a control device, a USB-to-serial interface board, a Bluetooth comprehensive tester, and multiple shielded boxes; the control device is electrically connected to the USB-to-serial interface board via a USB interface; multiple control serial ports of the USB-to-serial interface board are electrically connected to the control serial ports of the main control chips in each shielded box; multiple test serial ports of the USB-to-serial interface board are electrically connected to the test serial ports in each shielded box; multiple RF ports of the Bluetooth comprehensive tester are electrically connected to the RF switches in each shielded box; a communication connection is established between the control device and the Bluetooth comprehensive tester.
