[0050] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0051] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0052] The related art generally adopts a method of modifying the pixel value of a specified pixel point to an agreed value, generating a new image, displaying the new image on a display device, and comparing the pixel value of the specified pixel point displayed in the new image to determine whether it is the agreed value, so as to determine whether the display information playback status of the display device is normal. However, when a problem occurs inside the display device, this method cannot locate the abnormality inside the display device.

[0053] In addition, the related technology also continuously records the display information of the display device. When there is an abnormality in the display information playback status of the display device, the file of the corresponding time point is obtained from the recorded file according to the time point of the abnormality, and it is identified whether the abnormality in the display information playback status of the display device is a hardware abnormality of the display device. However, this method still cannot locate the abnormality inside the display device.

[0054] The embodiments of the present application provide a detection method for a display device, which determines the working state of the display device by using display information and the playing state of an audio signal, thereby locating an abnormality inside the display device. Figure 1 As shown, the method of this embodiment includes:

[0055] Step 101: in response to determining that the display device is in a startup state, obtaining playback information of the display device, wherein the playback information includes display information and an audio signal.

[0056] In specific implementation, the display device can be a light-emitting diode (LED) display screen, an organic light-emitting diode (OLED) display screen, or a sub-millimeter light-emitting diode (Mini LED) display screen. The application scenario of the display device can be an elevator advertising screen or an information prompt screen, and the elevator advertising screen is preferred here.

[0057] For example, when the elevator advertising screen is powered on and in the startup state, the playback information to be displayed on the elevator advertising screen sent by the background server is obtained, and the playback information includes display information and audio information.

[0058] Step 102: Determine the display information and the playing status of the audio signal.

[0059] In specific implementation, the playing state of the display information indicates whether the display information is abnormal, and the playing state of the audio signal indicates whether the audio signal is abnormal. Whether the display information and the audio signal are abnormal can be determined by the playing state.

[0060] Step 103: Determine the working state of the display device according to the display information and the playing state of the audio signal.

[0061] In a specific implementation, the working state of the display device is determined by utilizing the display information and the playing state of the audio signal, so that the abnormality existing inside the display device can be located.

[0062] Through the above scheme, when the display device is in the startup state, the playback information of the display device is obtained, the playback information includes display information and audio signals, the playback status of the display information and the audio signal is determined, and the working status of the display device is determined according to the playback status of the display information and the audio signal. By utilizing the playback status of the display information and the audio signal, the working status of the display device is determined, thereby locating the abnormality inside the display device.

[0063] In some embodiments, the display device includes a first control unit and a second control unit that are communicatively connected.

[0064] Step 102 includes:

[0065] Step A1, determining the playing status of the display information according to the status of the communication link between the first control unit and the second control unit.

[0066] In a specific implementation, for example, the first control unit is a signal operation controller (Signal Operation Control, SOC) mainboard, and the second control unit is a logic board (TCON).

[0067] The communication link between the signal operation controller main board and the logic board is a serial interface (V-by-One, VBO) link.

[0068] Whether there is any abnormality in the playing state of the display information is determined according to the state of the serialized interface link, thereby realizing the detection of the abnormality existing inside the display device.

[0069] In some embodiments, step A1 includes:

[0070] Step A11: obtaining a feedback signal provided by the second control unit to the first control unit.

[0071] Step A12: in response to determining that the feedback signal is at the first level, determining that the playing state of the display information is a normal state. or

[0072] Step A13: in response to determining that the feedback signal is at the second level, determining that the playing state of the display information is an abnormal state.

[0073] In specific implementation, for example, if the information displayed on the elevator advertising screen can be displayed normally, the prerequisite is that the serial interface link between the signal operation controller mainboard and the logic board establishes a correct link, and the operation controller mainboard needs to receive normal feedback signals from the logic board.

[0074] At this time, the feedback signal can be detected by operating the controller mainboard. In addition, in order to avoid the hardware link of the display screen of the elevator advertising screen being disconnected during operation, a module of an independent operation controller mainboard can also be set to detect the feedback signal. If the feedback signal is a first level, the first level represents a low level, and the playback status of the displayed information is a normal state. If the feedback signal is a second level, the second level represents a high level, and the playback status of the displayed information is an abnormal state, for example, an internal self-test (Built-in Self-Test, Bist) screen appears.

[0075] In some embodiments, the display device includes a sound emitting unit and a collecting unit.

[0076] Step 102 includes:

[0077] Step B1, using the acquisition unit to acquire audio data.

[0078] Step B2: determining the working state of the sound generating unit according to the audio data.

[0079] Step B3: determining the playing state of the audio signal according to the working state of the sound generating unit.

[0080] In a specific implementation, the display device includes a sound-generating unit and a collection unit. The sound-generating unit is, for example, a speaker, a sound, or a horn.

[0081] The acquisition unit includes, for example, a microphone and an audio collector.

[0082] The audio data of the sound unit is collected through the acquisition unit, the working state of the sound unit is determined according to the audio data, and the playing state of the audio signal is determined according to the working state of the sound unit. For example, if the audio data is stuck or there is no audio data, the working state of the sound unit is abnormal, and the playing state of the audio signal is abnormal.

[0083] In some embodiments, step 103 includes:

[0084] Step 1031: In response to determining that the display information and the playing status of the audio signal are both in normal status, determining that the working status of the display device is a first working status.

[0085] Step 1032: In response to determining that the playing state of the display information is an abnormal state and the playing state of the audio signal is a normal state, determining that the working state of the display device is a second working state.

[0086] Step 1033: In response to determining that the display information and the playing status of the audio signal are both in abnormal states, determining that the working state of the display device is a third working state.

[0087] In a specific implementation, when the display information and the playing status of the audio signal are both in normal status, the working status of the display status is the first status, and the first status indicates normal.

[0088] When the playback status of the displayed information is abnormal and the playback status of the audio signal is normal, the working status of the display device is determined to be the second working status. For example, the elevator advertising screen has no normal content display and can only display the internal self-test screen, and the sound is also output normally, then the working status of the display device is the second status. The second status indicates that there is an abnormality in the serialized interface link between the operation controller mainboard and the logic board.

[0089] When the display information and the playback status of the audio signal are both abnormal, it is determined that the working state of the display device is the third working state. For example, the elevator advertisement has no normal content displayed, and can only display the internal self-test screen, and the sound cannot be output normally. In this case, the working state of the display device is the third state. The third state indicates that the operation controller mainboard is abnormal, thereby locating the abnormality inside the display device.

[0090] In some embodiments, after determining that the working state of the display device is the second working state at step 1032, the method further includes:

[0091] Step C1, generate and send first alarm information to the server.

[0092] Step C2: receiving a restart instruction generated based on the first alarm information and fed back by the server, and controlling the first control unit of the display device to restart.

[0093] In a specific implementation, for example, after determining that the working state of the display device is the second state, the second state indicates that an abnormality exists in the serialized interface link between the operation controller mainboard and the logic board.

[0094] A first alarm message is generated and sent to the server, wherein the first alarm message indicates that an abnormality exists in the serialized interface link between the operation controller mainboard and the logic board.

[0095] Then, a restart instruction generated based on the first alarm information and fed back by the server is received to control the operation controller mainboard of the display device to restart, so as to solve the abnormality of the serial interface link between the operation controller mainboard and the logic board.

[0096] In some embodiments, at step 1033, after the first control unit controlling the display device is restarted, the method further includes:

[0097] Step D1, obtaining the playing information of the display device at the current moment, wherein the playing information at the current moment includes the display information and the audio signal at the current moment.

[0098] Step D2, determining the display information and the playing status of the audio signal at the current moment.

[0099] Step D3, determining the current working state of the display device according to the display information and the playing state of the audio information at the current moment.

[0100] Step D4, in response to determining that the current working state of the display device is the second working state or the third working state, generating and sending a second alarm message to the server.

[0101] In a specific implementation, for example, after the operation controller mainboard that controls the display device is restarted, the playback information of the display device at the current moment is obtained, and the playback information at the current moment includes the display information and audio signal at the current moment. The working state of the display device at the current moment is determined based on the playback state of the display information and audio information at the current moment, so as to determine whether the restart of the operation controller mainboard has solved the abnormality of the serial interface link between the operation controller mainboard and the logic board.

[0102] When the current working state of the display device is the second working state or the third working state, indicating that restarting the operation controller main board has not solved the abnormality problem of the serial interface link between the operation controller main board and the logic board, a second alarm message is generated and sent to the server, and the second alarm message indicates that restarting the operation controller main board has not solved the abnormality problem of the serial interface link between the operation controller main board and the logic board.

[0103] In some embodiments, in step D4, after determining that the working state of the display device is the third working state, the method further includes:

[0104] Step E1, generating and sending third alarm information to the server.

[0105] In a specific implementation, for example, after determining that the working state of the display device is the third working state, a third alarm message is generated and sent to the server, and the third alarm message indicates that the operation controller mainboard is abnormal.

[0106] In some embodiments, when the playback status of the display information is an abnormal status, the display device displays preset initial display information.

[0107] In a specific implementation, when the playback status of the display information is abnormal, that is, no normal content is displayed, only the preset initial display information can be displayed.

[0108] In some embodiments, the preset initial display information includes a white picture, a red picture, a green picture, a blue picture and / or a black picture.

[0109] During specific implementation, the preset initial display information includes a white picture, a red picture, a green picture, a blue picture and / or a black picture, and the preset initial display information can be switched in turn.

[0110] In some embodiments, the first control unit is a main control unit, and the second control unit is a logic control unit.

[0111] In a specific implementation, the first control unit is a main control unit, which may be a signal operation control (SOC) mainboard, and the second control unit is a logic control unit, which may be a logic board (TCON).

[0112] This application describes the detection process of the display device in detail using an embodiment, such as Figure 2A , 2B As shown, the details are as follows:

[0113] The content played on the elevator screen is generally sent to the elevator screen's signal operation control (SOC) mainboard through the server. The signal operation control (SOC) mainboard is connected to the logic board (TCON) via a communication link for a serial interface (V-by-One, VBO) link.

[0114] Detection process: After the elevator screen is started, the background server sends the content to play. The operation controller mainboard transmits the signal through the serial interface. After the serial interface link between the operation controller mainboard and the logic board establishes a correct link, the display screen displays the content normally.

[0115] The level of the hardware pin (LOCKN) is monitored in real time (i.e., the feedback signal provided by the second control unit to the first control unit). When LOCKN=0, it indicates a low level, and the display screen of the elevator screen displays the content normally without any abnormality.

[0116] When LOCKN=1, it indicates a high level. The elevator screen cannot display the content normally and an abnormality occurs. The detection module continues to detect the audio signal (Audio) of the speaker. If a normal audio signal is detected, the hardware link (i.e., communication link) for transmitting signals between the SoC (i.e., the first control unit) mainboard and TCON (i.e., the second control unit) is abnormal, and the display abnormality (i.e., the first alarm message) is reported to the server through the network of the SoC mainboard (i.e., the first control unit); if the sound is abnormal, the SoC (i.e., the first control unit) may have a problem, and the background will determine the abnormality through the network and perform on-site maintenance (i.e., the third alarm message).

[0117] Among them, the hardware link (i.e., communication link) for transmitting signals between the SoC (i.e., the first control unit) mainboard and the TCON (i.e., the second control unit) is abnormal, and the abnormality (i.e., the first alarm information) is reported to the background server through the network of the SoC mainboard (i.e., the first control unit). The server can issue an instruction to let the SoC mainboard (i.e., the first control unit) restart to try to solve the problem. If the problem still exists, on-site maintenance will be arranged.

[0118] Audio signal detection can collect the signal of the speaker through a microphone (MIC) to confirm whether the audio signal is normal.

[0119] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0120] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims.
