Description

Technical Field

[0001] This invention relates to the field of intelligent electronic device technology, specifically to an automatic rotating screen intelligent audio-visual system and control method. Background Technology

[0002] With the rapid development of smart terminal technology, the functions of audio and video devices are becoming increasingly rich, and users' demands for the flexibility and adaptability of device display effects are constantly increasing. Currently, some smart audio and video devices on the market are equipped with rotatable display screens to meet users' needs for display orientation in different usage scenarios.

[0003] Currently, there are two main technical solutions for achieving screen orientation adjustment: Manual rotation mode: The device itself does not have an automatic sensing function. Users need to manually select the target display orientation through the device's software settings interface, and then physically rotate the device's screen or the entire device to the corresponding orientation to match the displayed content with the screen's physical orientation. This method is cumbersome, lacks intelligence, and provides a poor user experience. Users need to perform two independent and must match steps, which is prone to errors.

[0004] Integrated sensor mode on the main control board: Some small devices integrate the rotation sensor chip used to detect the device's orientation directly onto the main control board. The main control board is usually fixedly installed inside the device body. Although this solution can achieve automatic rotation, the structural design is severely limited because the sensor module is bound to the main control board. The screen module, speaker body, and main control board must be closely integrated in physical layout, limiting the diversity of product form and modular design.

[0005] Existing technologies suffer from problems such as complex operation, low level of intelligence, or limited structural design, which hinders product form innovation and modular installation. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic rotating screen intelligent audio and video system and control method to solve the problems of rigid structural design and inconvenient installation in the prior art mentioned in the background.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatic rotating screen intelligent audio-visual system and control method includes a display module, a main device module, and a cable assembly. The cable assembly connects the display module and the main device module. The display module includes a display screen and a rotation sensing module. The rotation sensing module can be installed in a manner that includes being fixedly mounted on the back of the display screen or integrated into the internal structure of the display screen, and is used to sense the spatial attitude changes of the display module in real time and generate corresponding attitude data. The main device module includes a main control board, an audio unit, and a power supply unit. The main control board, audio unit, and power supply unit are fixedly mounted within the housing of the main device module. The main control board is used to process audio-visual data, execute system control logic, and generate display drive signals. The cable assembly includes a display drive line and a sensing communication line. The display drive line connects the main control board and the display screen and transmits the display drive signals from the main control board to the display screen. The sensing communication line is independently configured relative to the display drive line and connects the rotation sensing module and the main control board, transmitting the attitude data of the rotation sensing module to the main control board. The main control board functions to receive and parse the attitude data from the rotation sensing module, determine the current orientation angle of the display module based on the parsing results, and accordingly control the display screen to adjust the screen orientation of its content so that the displayed content matches the orientation angle of the display module.

[0008] Preferably, the rotation sensing module includes a multi-axis inertial measurement unit and a first communication interface. The multi-axis inertial measurement unit is used to detect the acceleration and angle changes of the display module on at least two coordinate axes, and the first communication interface is connected to one end of the sensing communication line.

[0009] Preferably, the main control board includes a display controller and a second communication interface. The display controller generates display drive signals, and the second communication interface is connected to the other end of the induction communication line to receive attitude data from the rotation sensing module. The multi-axis inertial measurement unit establishes a data path with the display controller through the first communication interface, the induction communication line, and the second communication interface.

[0010] Preferably, the rotation sensing module further includes a signal processing unit, which is connected between the multi-axis inertial measurement unit and the first communication interface. The signal processing unit is used to perform analog-to-digital conversion, filtering, and / or data formatting on the raw sensing signal output by the multi-axis inertial measurement unit, and generate attitude data.

[0011] Preferably, the rotation sensing module is installed on the back panel or bracket of the display screen by means of adhesive bonding, snap-fit, or screw fixing, and the sensing communication line is a flexible circuit board or a flexible flat cable.

[0012] Preferably, the system further includes a user setting module, which provides a user interface allowing users to select a display orientation control mode. The display orientation control mode includes at least an automatic rotation mode and a forced display mode. In the automatic rotation mode, the main control board automatically controls the display screen and adjusts the display orientation based on the attitude data fed back by the rotation sensing module. In the forced display mode, the main control board ignores the attitude data from the rotation sensing module and displays according to a fixed display orientation specified by the user.

[0013] Preferably, the main control board also includes, in automatic rotation mode, performing a display direction switching operation only when the orientation angle of the display module is detected to be stable and continuous within a preset threshold angle range for a first preset duration. The threshold angle range is less than 45° or greater than 45°, and the first preset duration is greater than 1 second.

[0014] Preferably, the main body module of the device further includes a structural connector for detachably or rotatably connecting to the display module. The relative positional relationship between the display module and the main body module of the device is any one of separable, flip-up, or rotatable connection methods, such as snap-fit ​​or hinge.

[0015] Preferably, the physical assembly method of the display module and the main device module satisfies the following: the rotation sensing module can sense the orientation change of the display module relative to the ground caused by user operation or the weight of the display module itself.

[0016] Preferably, a control method for an automatic rotating screen intelligent audio-visual system includes: Step S1: The system is powered on and initialized. The rotation sensing module begins to sense the spatial attitude of the display module in real time and generates attitude data. Step S2: The rotation sensing module continuously sends attitude data to the main control board via the sensing communication line; Step S3: The main control board receives and parses the attitude data, calculates the current orientation angle of the display module, and calculates the current orientation angle based on the components of gravitational acceleration on the X and Y axes in the attitude data. The tilt angle of the display module relative to the horizontal plane is calculated by the arctangent function. A tilt angle less than 45° is mapped to a horizontal display direction, and a tilt angle greater than 45° is mapped to a vertical display direction. Step S4: The main control board determines the display direction control mode currently set by the system; Step S5: If the current mode is automatic rotation, the main control board compares the current orientation angle with the reference orientation angle corresponding to the currently effective display direction; Step S6: If the difference between the current orientation angle and the reference orientation angle exceeds a preset angle threshold and the stabilization time exceeds a preset delay, the main control board generates a new display drive signal that matches the current orientation angle; Step S7: The main control board sends a new display drive signal to the display screen through the display drive line and controls the display screen to switch the display orientation; Step S8: If the current display mode is forced, the main control board will keep the current display orientation unchanged and ignore the attitude data.

[0017] The technical effects and advantages of this invention are as follows: 1. This automatic rotating screen intelligent audio and video system and control method, by setting up an induction communication line independent of the display drive line, realizes the separate transmission of attitude data and display drive signal, effectively avoids signal interference between the two, improves the stability and accuracy of attitude data transmission, and provides data guarantee for precise adjustment of display direction.

[0018] 2. The automatic rotating screen intelligent audio and video system and control method have an added signal processing unit in the rotation sensing module to perform analog-to-digital conversion, filtering and other processing on the original sensing signal, which further optimizes the quality of attitude data, reduces the impact of environmental interference on attitude detection, and improves the accuracy of attitude judgment.

[0019] 3. The automatic rotating screen intelligent audio and video system and control method have two control modes: automatic rotation and forced display. Users can flexibly choose according to their actual needs, which greatly improves the adaptability of the device and the user experience. In automatic rotation mode, by judging the preset angle threshold and the stable duration, frequent switching caused by slight shaking is avoided, ensuring the stability and rationality of the display direction switching.

[0020] 4. The automatic rotating screen intelligent audio and video system and control method adopt multiple detachable or rotatable connection methods between the display module and the main device module to adapt to different installation and usage scenarios, while ensuring that the rotation sensing module can accurately sense changes in orientation, thus improving the versatility and practicality of the device.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention discloses an automatic rotating screen intelligent audio-visual system and control method, according to the appendix. Figures 1-3 As shown, the system includes a display module, a main device module, and a cable assembly. The cable assembly connects the display module and the main device module. The display module includes a display screen and a rotation sensor module. The rotation sensor module can be fixedly mounted on the back of the display screen or integrated into its internal structure. It is used to sense changes in the spatial posture of the display module in real time and generate corresponding posture data. The main device module includes a main control board, an audio unit, and a power supply unit. These components are fixedly mounted within the housing of the main device module. The main control board processes audio and video data, executes system control logic, and generates display drive signals. The cable assembly includes a display drive line and a sensor communication line. The display drive line connects the main control board and the display screen, transmitting the display drive signals from the main control board to the display screen. The sensor communication line is independent of the display drive line and connects the rotation sensor module and the main control board, transmitting the posture data from the rotation sensor module to the main control board. The main control board receives and analyzes the posture data from the rotation sensor module, determines the current orientation angle of the display module based on the analysis results, and accordingly controls the display screen to adjust the orientation of its displayed content to match the orientation angle of the display module.

[0025] Furthermore, the rotation sensing module includes a multi-axis inertial measurement unit and a first communication interface. The multi-axis inertial measurement unit is used to detect the acceleration and angle changes of the display module on at least two coordinate axes, and the first communication interface is connected to one end of the sensing communication line.

[0026] Furthermore, the main control board includes a display controller and a second communication interface. The display controller generates display drive signals, and the second communication interface connects to the other end of the induction communication line to receive attitude data from the rotation sensing module. The multi-axis inertial measurement unit establishes a data path with the display controller through the first communication interface, the induction communication line, and the second communication interface. By setting up an induction communication line independent of the display drive line, the attitude data and display drive signals are transmitted separately, effectively avoiding signal interference between the two, improving the stability and accuracy of attitude data transmission, and providing data assurance for precise adjustment of the display direction.

[0027] Specifically disclosed, the rotation sensing module also includes a signal processing unit. This unit connects to the multi-axis inertial measurement unit (IMU) and the first communication interface. The signal processing unit performs analog-to-digital conversion, filtering, and / or data formatting on the raw sensing signals output by the IMU, generating attitude data. The addition of a signal processing unit to the rotation sensing module, which performs analog-to-digital conversion and filtering on the raw sensing signals, further optimizes the quality of the attitude data, reduces the impact of environmental interference on attitude detection, and improves the accuracy of attitude judgment.

[0028] Specifically disclosed, the rotation sensing module is installed on the back panel or bracket of the display screen by means of adhesive bonding, snap-on fasteners or screws, and the sensing communication line is a flexible circuit board or a flexible flat cable.

[0029] It is worth emphasizing that the system also includes a user settings module. This module provides a user interface, allowing users to select the display orientation control mode. The display orientation control modes include at least an automatic rotation mode and a forced display mode. In automatic rotation mode, the main control board automatically controls the display screen and adjusts the display orientation based on the posture data fed back by the rotation sensor module. In forced display mode, the main control board ignores the posture data from the rotation sensor module and displays according to the fixed display orientation specified by the user. By offering both automatic rotation and forced display control modes, users can flexibly choose according to their actual needs, greatly improving the device's adaptability and user experience. In automatic rotation mode, by using preset angle thresholds and stabilization time, frequent switching caused by slight shaking is avoided, ensuring the stability and rationality of display orientation switching.

[0030] It is worth emphasizing that the main control board also has the function of switching the display direction only when the orientation angle of the display module is detected to be stable within a preset threshold angle range for a first preset duration in automatic rotation mode. The threshold angle range is less than 45° or greater than 45°, and the first preset duration is greater than 1 second.

[0031] It is particularly important to emphasize that the main body module of the device also includes structural connectors for detachable or rotatable connection with the display module. The relative positional relationship between the display module and the main body module can be any of the following: detachable, flip-up, or rotatable, such as a snap-fit ​​or hinge connection. The display module and the main body module employ multiple detachable or rotatable connection methods to adapt to different installation and usage scenarios, while ensuring that the rotation sensor module can accurately detect changes in orientation, thus improving the versatility and practicality of the device.

[0032] It is particularly important to emphasize that the physical assembly method of the display module and the main device module satisfies the requirement that the rotation sensing module can sense the orientation change of the display module relative to the ground caused by user operation or the weight of the display module itself.

[0033] It is particularly important to emphasize the control methods of the automatic rotating screen intelligent audio-visual system. These control methods include: Step S1: The system is powered on and initialized. The rotation sensing module begins to sense the spatial attitude of the display module in real time and generates attitude data. Step S2: The rotation sensing module continuously sends attitude data to the main control board via the sensing communication line; Step S3: The main control board receives and parses the attitude data, calculates the current orientation angle of the display module, and calculates the current orientation angle based on the components of gravitational acceleration on the X and Y axes in the attitude data. The tilt angle of the display module relative to the horizontal plane is calculated by the arctangent function. The tilt angle is less than 45° and mapped to the horizontal display direction, and the tilt angle is greater than 45° and mapped to the vertical display direction. Step S4: The main control board determines the display direction control mode currently set by the system; Step S5: If the current mode is automatic rotation, the main control board compares the current orientation angle with the reference orientation angle corresponding to the currently active display direction; Step S6: If the difference between the current orientation angle and the reference orientation angle exceeds the preset angle threshold and the stabilization time exceeds the preset delay, the main control board generates a new display drive signal that matches the current orientation angle; Step S7: The main control board sends a new display drive signal to the display screen through the display drive line and controls the display screen to switch the display orientation; Step S8: If the current display mode is forced, the main control board will keep the current display direction unchanged and ignore the attitude data.

[0034] Working Principle: The core working principle of the automatic rotating screen intelligent audio-visual system of this invention is based on a collaborative workflow of "attitude sensing - data transmission - analysis and judgment - display control," specifically as follows: After the system is powered on, the power supply unit supplies power to each module, the rotation sensing module starts and senses the spatial attitude changes of the display module in real time; the multi-axis inertial measurement unit collects the original acceleration or angle signals of the display module on multiple coordinate axes, and generates standard attitude data after analog-to-digital conversion, filtering, and data formatting by the signal processing unit; the attitude data is stably transmitted to the main control board through a sensing communication line independent of the display drive line via the communication interface; the main control board analyzes the attitude data, calculates the current orientation angle of the display module, and executes the corresponding control logic in conjunction with the display direction control mode selected by the user through the user setting module; if it is the automatic rotation mode, the main control board compares the current orientation angle with the reference orientation angle, and when the difference exceeds the preset threshold and the stable time reaches the target, it generates a display drive signal matching the current orientation, which is transmitted to the display screen through the display drive line to realize the display direction switching; if it is the forced display mode, the main control board ignores the attitude data and maintains the fixed display direction specified by the user. Throughout the process, the structural connectors ensure the relative motion stability between the display module and the main body module of the device, ensuring that the rotation sensing module can accurately capture changes in orientation and achieve precise matching between the displayed content and the orientation angle.
