[0037] The audio test module 102 is used to test the audio path of the motherboard under test 107. The audio output component 1021 outputs a standard audio file to the motherboard under test 107. After the motherboard under test 107 receives and processes the file, the audio signal generated by the motherboard under test 107 is acquired by the audio acquisition component 1022.

[0038] The communication module 103 includes an infrared transmitter 1031 and a key simulation component 1032. The infrared transmitter 1031 is communicatively connected to the infrared input interface 1076, and the key simulation component 1032 is electrically connected to the key input interface 1077.

[0039] The communication module 103 is used to test the infrared response function and physical button response function of the motherboard under test 107.

[0040] The interactive control module 104 is connected to the main controller 108, and through the main controller 108, it is connected to the video test module 101, the audio test module 102, and the communication module 103 respectively.

[0041] The interactive control module 104 is used to control the start and stop of each module, and to record test results, exception information, etc.

[0042] The interactive control module 104 obtains the display pattern from the video input component 1012 in the video testing module 101, compares the display pattern with the static image, performs an approximation comparison, and determines whether the display pattern is normal. It does not rely on manual visual inspection or high-definition cameras for display effect verification. Through automated testing, it automatically generates test signals, controls data acquisition, and switches test scenes according to a preset test plan, without requiring frequent manual intervention.

[0043] The interactive control module 104 obtains audio signals from the audio test module 102, compares the audio signals with standard audio files, and determines whether the audio function of the motherboard 107 under test is normal.

[0047] In some embodiments, the motherboard under test 107 further includes a power input interface 1071, and the test system further includes: The power module 105 includes an internal power supply component, which is electrically connected to the interactive control module 104 and the power input interface 1071.

[0048] The power module 105 supplies power to the motherboard under test 107. When the load on the motherboard under test 107 is low, it is powered by the onboard power supply of the internal power supply component. Stable power output ensures the continuity and reliability of the testing process, reduces test errors caused by power supply problems, and improves the credibility of test results.

[0049] In some embodiments, the power module 105 further includes an external power supply interface, which is connected to the interactive control module 104 and the power input interface 1071 respectively, and a programmable power supply is provided between the external power supply interface and the power input interface 1071.

[0050] When the motherboard under test 107 is under heavy load, it is powered by an external power supply device via a programmable power indicator. The power module 105 supports switching between internal and external power supply modes to adapt to different testing scenarios. This expands the scope of testing, enabling more comprehensive verification of the motherboard's power adaptability and anti-interference capabilities, and improving testing reliability.

[0051] While supplying power, the power module 105 also collects the operating current of the motherboard under test 107. The interactive control module 104 filters the collected operating current to remove noise interference and uses a moving average filtering algorithm to improve the accuracy and stability of the current data. The operating current is compared with a preset current threshold. If the operating current exceeds the current threshold, it is determined that there may be an overcurrent fault. The motherboard under test 107 is immediately powered off to prevent damage to the motherboard under test 107, and the abnormal event is reported at the same time.

[0052] The current threshold can be set to 120% of the device's rated current.

[0057] The native DP interface connects to the DP switching controller, which can be directly connected to a DP-type video transmission interface, or it can be connected to a VGA-type video transmission interface via a DP to VGA converter.

[0058] The DP switching controller has a built-in IC9612 chip.

[0059] The native HDMI interface connects to the HDMI switcher, which in turn connects to both the DVI and HDMI video transmission interfaces.

[0060] The HDMI switching controller has a built-in GSV6705 chip.

[0061] In some embodiments, the video input component 1012 includes at least one type of video receiving interface, which is electrically connected to the video output interface 1073.

[0062] Video receiving interface types include, but are not limited to: LVDS, DP, eDP, and VBO.

[0063] It supports receiving video in multiple formats, fully verifies the performance of the motherboard's 1073 video output interface, ensures that the motherboard can adapt to different display devices, and improves the test system's coverage of video output functions.

[0064] Since there are many types of video interfaces, and different types of interfaces receive different types of display patterns, different types of video receiving interfaces can be uniformly converted into HDMI interfaces inside the video input component 1012. An HDMI four-in-one switch is set up, and the HDMI four-in-one switch is connected to the HDMIRx interface of the interactive control module 104 to realize data interaction.

[0065] For example, such as Figure 5 As shown, an LT2611 chip can be installed within the video input component 1012 to convert LVDS to HDMI. A CS5263 chip can be installed within the video input component 1012 to convert eDP to HDMI. A CS5218 chip can be installed within the video input component 1012 to convert DP to HDMI. An IT6265 chip can be installed within the video input component 1012 to convert VBO to HDMI. A four-way HDMI selector switch connects to the LT2611, CS5218, IT6265, and CS5263 chips respectively.

[0066] In some embodiments, the audio output component 1021 includes at least one type of audio transmission interface electrically connected to the audio input interface 1074.

[0068] like Figure 6 As shown, the audio output component 1021 also includes a DP controller, an HDMI controller, a codec, a DP switching controller, an HDMI switching controller, and a power amplifier (PA).

[0069] The DP controller connects to the DP switching controller, and the DP switching controller connects to the DP type audio transmission interface.

[0070] The DP switching controller has a built-in IC9612 chip.

[0071] The HDMI controller connects to the HDMI switch controller, which in turn connects to an HDMI-type audio transmission interface.

[0072] The HDMI switching controller has a built-in IC9642 chip.

[0073] The Codec connects to the DA, and the PA connects to the AUDIO type audio transmission interface.

[0074] The audio feedback component 1022 is configured with a codec, which is connected to the main controller 108.

[0075] It can cover multiple audio input interfaces according to the 1074 standard, test the motherboard's compatibility with different audio formats, ensure that the motherboard can be adapted to a variety of audio input devices, and enhance the applicability of the test system.

[0076] For standard audio files transmitted via HDMI and DP interfaces, they can be coupled with the video signal emitted by the video test module 101 and transmitted to the motherboard under test 107 via the video transmission interface.

[0077] In some of these embodiments, such as Figure 7 As shown, the infrared transmitter 1031 is positioned opposite the infrared input interface 1076, and the interactive control module 104 controls the infrared transmitter 1031 to send an infrared modulation signal to the infrared input interface 1076.

[0078] Specifically, the infrared transmitter 1031 can be configured as a pulse width modulation controller, and the communication module also includes an infrared transmitting interface, which corresponds to the infrared input interface 1076. The pulse width modulation controller adjusts the pulse signal to generate an infrared modulated signal, which is then transmitted through the infrared transmitting interface to the infrared input interface 1076.

[0079] The accuracy of infrared testing is ensured through precisely aligned infrared signal transmission paths and controllable infrared modulation signals. Furthermore, by simulating real remote control operation scenarios, the sensitivity and reliability of the motherboard's infrared receiving function are verified, enhancing the realism of the test.

[0080] In some embodiments, the key simulation component 1032 includes a key generator and a digital-to-analog converter, wherein the key generator controls the digital-to-analog converter to connect and interact with the key input interface 1077.

[0081] By using digital-to-analog conversion to accurately simulate key signals, stable key inputs can be repeatedly generated, avoiding testing errors caused by differences in the force and duration of manual key presses. This enables automated batch testing, improving the efficiency and consistency of key function testing.

[0082] When controlling the motherboard 107 under test via physical buttons, different voltage values ​​are generated by shorting or pressing the buttons, which can be converted by an analog-to-digital converter to achieve different button effects. It can also be operated via an infrared remote control.

[0083] The button simulation component 1032 also includes a voltage-type button interface, a short-circuit button interface, and a general-purpose input / output controller.

[0084] The general-purpose input / output controller is connected to a short-circuit button interface. The button generator controls the opening and closing of the analog switch of the general-purpose input / output controller and sends signals to the motherboard under test 107 through the short-circuit button interface.

[0085] The digital-to-analog converter is connected to a voltage-type button interface, and the button generator controls the digital-to-analog converter to generate different voltages to simulate the action of physical buttons.

[0086] After the test system sends a button or infrared modulation signal, the video test module 101 displays the processed image of the motherboard under test 107, identifies the processed image, and determines whether the motherboard under test 107 performs the corresponding processing of the button or infrared modulation signal. Furthermore, it iterates through all buttons to realize the detection of all button functions of the motherboard under test 107.

[0087] In some embodiments, the motherboard under test 107 also includes a debug interface 1078, and the test system further includes: The debugging control module 106 is connected to the interactive control module 104 and includes a serial port interface, a serial bus 1061 and a network communication component 1063. The serial port interface and the serial bus 1061 are both electrically connected to the debugging interface 1078, and the network communication component 1063 is wirelessly connected to the motherboard under test 107.

[0088] The debug control module 106 provides multiple debugging methods, including wired and wireless connections, enhancing the interaction between the test system and the motherboard. This facilitates real-time acquisition of the motherboard's internal status, quickly pinpointing the root cause of test anomalies, and improving troubleshooting efficiency. It also expands the functional boundaries of the test system, enabling it to not only perform functional testing but also support in-depth debug analysis.

[0089] The debug control module 106 is mainly used to communicate with the motherboard under test 107, responsible for sending commands to the motherboard under test 107 and obtaining information corresponding to the commands from the motherboard under test 107. The debug control module 106 and the motherboard under test 107 can communicate via protocols such as ADB, SSH, and serial port.

[0090] The debugging control module 106 obtains the resolution information, frame rate information and color mode information generated when processing the static image from the motherboard under test 107, and sends the resolution information, frame rate information and color mode information to the interactive control module 104 to further compare whether the resolution information, frame rate information and color mode information are consistent with the information of the static image.

[0091] like Figure 3 As shown, during the motherboard testing process, the system first checks the power supply to the motherboard under test (107). If a power supply abnormality is detected, the abnormality is recorded, and the system is powered off and exits. If the power supply is normal, the system checks whether the motherboard under test (107) has been programmed. If not, the program is programmed. After programming is completed, the system checks whether a serial number has been written. If not, the serial number is written. If so, the system executes the test items sequentially and records the test results. After the test, the motherboard under test (107) is powered off, and a test report is generated in the interactive control module (104).

[0092] The test items include, but are not limited to, repeated power-on and power-off checks, audio and video input / output signal checks, and button checks.

[0093] Through the description of several embodiments of the motherboard testing system of this utility model, it can be seen that the embodiments of the motherboard testing system of this utility model have at least one or more of the following advantages: 1.
