DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0024] The detection method of the automated testing flat-panel decoder board is a production-ready board specially designed to cooperate with the automated detection system of the flat-panel decoder board. The decoder board has been optimized for PCB circuits and software coordination and adjustment, and detects the quality of the flat-panel decoder board through real-time data sampling and signal processing. Since existing flat-panel boards are usually inspected manually, not only is the professional quality of the inspectors required to be high, but also due to the test instruments used and the operating errors of the personnel, it is impossible to achieve a unified test specification. Therefore, the flat-panel automated testing board technology will be the development trend of multimedia audio and video decoder board detection technology in the future. In this regard, the present application proposes a test flat-panel decoder board and an automatic detection method thereof. Specifically, Figure 1 A structural schematic diagram of a test flat-panel decoder board of the present application is shown.

[0026] It should be noted that, in the present embodiment, the proposed test flat panel decoder board optimizes the circuit design. Signal test points are obtained by making holes in the PCB without affecting the normal circuit of the decoder board, and the signal points to be tested are connected to the copper-clad via positions on the top of the PCB, so that the circuits of each signal test point do not affect each other and are not affected by external interference. In specific applications, the test points can be identified and used by non-professional testers, and then combined with an external test pin to realize automatic testing of the flat panel to be tested.

[0027] The test flat panel decoder board described in this embodiment is composed of internal integrated servo control, audio decoder, video decoder, DOBLY, AC-3 decoder, DTS, HDCD decoder, built-in karaoke, and other functional modules, wherein, specifically, the main control unit 10 is specifically a main control MCU 101, and the storage unit 30 is a synchronous dynamic random access memory 301, wherein the main control MCU 101 is compatible with the synchronous dynamic random access memory 301; The audio and video unit 20 includes an audio block 201 and a video block 202, and the input and output unit 40 includes an input block 401 and an output block 402, wherein the audio block 201 is used to receive the audio data input by the input block 401 and output it through the output block 402 after processing, and the video block 202 is used to receive the video data input by the input block 401 and output it through the output block 402 after processing.

[0028] Furthermore, the audio and video unit 20 has DOBLY, AC-3, DTS and HDCD decoding functions, wherein the audio block 201 includes an audio decoder, and the video block 202 includes a video decoder.

[0029] Furthermore, the audio and video formats input by the input block 401 include IR format, VFD format and karaoke format, the connection interface of the input block 401 includes a USB interface and a memory card interface, and the data output by the output block 402 includes 2CH / 6CH audio data and various video data. Among them, IR corresponds to Impulse Response (IR), VFD corresponds to Variable-frequency Drive (VFD), and karaoke is a well-known audio accompaniment system.

[0030] Furthermore, the main control MCU 101 is electrically connected to the tablet to be tested, is compatible with 1X16 / 4X16 synchronous dynamic random access memory, and has an external SPI_8Mbit FLASH program memory.

[0031] Figure 2 A flow chart of a method for automatically detecting a test flat-panel decoder board of the present application is shown.

[0032] like Figure 2 As shown, the present application discloses a method for automatically detecting a test flat panel decoder board, comprising the following steps: S202, identifying whether the tablet to be tested is connected to the test; S204, receiving a control instruction from the user end, and controlling the external cylinder to operate based on the control instruction so that the test ejector pin contacts the test point; S206, automatically detecting the panel to be tested based on the testing panel decoding board, and visually displaying the detection result.

[0033] It should be noted that, in this embodiment, when the test flat panel decoder board described in the above embodiment is used to detect the flat panel to be tested, it is necessary to first identify whether the flat panel to be tested is connected for detection, and when it is judged to be connected, receive the control instruction fed back by the user, so as to control the external cylinder based on the control instruction. The specific control method is cylinder compression, so that the test ejector pin and the test point of the flat panel to be tested are in contact with each other to transmit an electrical signal, so that the flat panel to be tested can be automatically detected based on the test flat panel decoder board. The specific detection process will be described in the subsequent instructions. In addition, in this embodiment, the detection results are also displayed visually, so that the entire process only requires the user to operate the feedback button to give the control instruction and observe the detection results with the naked eye, without the use of any testing equipment, and the professional knowledge requirements for the detection personnel are not as high as those of the prior art using professional researchers for testing, thereby saving labor costs.

[0034] According to an embodiment of the present invention, when the panel to be tested is automatically detected based on the test panel decoder board, the transmission signal parameters of the test points are compared with preset theoretical parameters, so that the comparison result is used as the detection result.

[0035] It should be noted that, in this embodiment, a corresponding comparison algorithm is pre-stored in the main control MCU of the test flat panel decoder board, which can compare the transmission signal parameters of the test point with the preset theoretical parameters. The comparison can be used to identify which signal channels and signal points in the current flat panel to be tested are abnormal and which meet the standards. The comparison results obtained can be list results or statistical results. Both list results and statistical results are obtained by comparison and detection using a pre-stored comparison algorithm, and the comparison results are used as the detection results.

[0036] According to an embodiment of the present invention, during visual display, the transmission signal parameters of the test point and the signal parameters with abnormalities in the preset theoretical parameters are extracted for feature display.

[0037] It should be noted that in this embodiment, since the final test results will be displayed visually to the user, when performing the visual display, whether it is displaying the list results or the statistical results, in order to facilitate the user to see the abnormal information at a glance, it is necessary to extract the transmission signal parameters of the test point and the signal parameters with abnormalities in the preset theoretical parameters for feature display during the visual display, wherein the feature display of the list results may be color-marked display or others, and the feature display of the statistical results may be bold font display or others.

[0038] It is worth mentioning that the identification of whether the tablet to be tested is connected to the test specifically includes: Detect access responses in a test package, where If the access response is of a preset type, it is determined to be an access detection. If the access response is not of the preset type, it is determined to be a non-access detection.

[0039] It should be noted that, in this embodiment, the panel to be tested needs to be placed in a test package before it can be tested. Therefore, it is necessary to respond to the object placed in the test package to determine whether it is the panel to be tested. If the access response is of a preset type, it indicates that the object in the current test package is the panel to be tested. At this time, it is judged as an access detection, and the panel to be tested in the current test package can be tested. If the access response is not of the preset type, it indicates that the object in the current test package is not the panel to be tested. At this time, it is judged as a non-access detection, and the object in the test package is not detected.

[0040] It is worth mentioning that the access response in the detection test package specifically includes: The access response is identified based on a preset response mechanism, wherein: Obtaining the access response based on interface wired response identification; and / or The access response is obtained based on the wireless communication response identification.

[0041] It should be noted that, in this embodiment, the access response mechanism is divided into a wired response mechanism and a wireless response mechanism, wherein, specifically, the access response is obtained based on the interface wired response identification, that is, when the panel to be tested is placed in the test package, it can communicate with the preset interface by wire, such as the type-c interface response; and / or the access response is obtained based on the wireless communication response identification, such as the Bluetooth mechanism communication response.

[0042] It is worth mentioning that receiving the control command from the user end and controlling the external cylinder operation based on the control command specifically include: Get the operation data of the preset button; Identifying the control instruction based on the operation data, wherein the control instruction includes a start test instruction, a pause test instruction, and a stop test instruction; Based on the test start instruction, the external cylinder is controlled to start the compression operation so that the test ejector pin contacts the test point of the plate to be tested; Based on the test pause instruction, the external cylinder is controlled to interrupt the compression operation so that the test ejector pin is disconnected from the test point of the plate to be tested; Based on the test termination instruction, the external cylinder operation is controlled to terminate the compression operation so that the test ejector pin returns to the starting position.

[0043] It should be noted that, in this embodiment, when the test flat panel decoder board is used to automatically detect the flat panel to be tested, the user only needs to operate a preset button (generally a green button) and observe the detection result. Therefore, there are differences in the control methods corresponding to different button operation behaviors. Specifically, the control instruction is identified based on the operation data, wherein the control instruction includes a start test instruction, a pause test instruction, and a stop test instruction. The operation data corresponding to different instructions are also different. For example, pressing the first level corresponds to the start test instruction, pressing the second level corresponds to the pause test instruction, and pressing the third level corresponds to the stop test instruction. In order to protect the test ejector and the test point, when the test is terminated, it is necessary to first go through the pause test stage. Further, based on the start test instruction, the external cylinder operation is controlled to start the compression operation so that the test ejector and the test point of the flat panel to be tested are in contact with each other; based on the pause test instruction, the external cylinder operation is controlled to interrupt the compression operation so that the test ejector and the test point of the flat panel to be tested are disconnected; based on the stop test instruction, the external cylinder operation is controlled to terminate the compression operation so that the test ejector returns to the starting position.
