[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0043] In order to further explain the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the specific implementation methods, structures, features and effects of the utility model application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0044] Combine the following Figures 1 to 3 The integrated machine control architecture according to some embodiments of the present invention is described.

[0045] In one embodiment, Figure 1 As shown, a LED all-in-one control architecture is provided, which includes a first control box 100, a second control box 200 and an LED display screen 300; wherein the first control box 100 includes an operating system component 101, and the second control box 200 includes a power supply control module 201 and a sending card 202; the output end of the power supply control module 201 is respectively connected to the operating system component 101, the sending card 202 and the LED display screen 300, for supplying power to the operating system component 101, the sending card 202 and the LED display screen 300; the operating system component 101 is connected to the input end of the sending card 202, for receiving a video source signal , audio signal and control signal, and sends the video source signal, audio signal and control signal to the sending card 202; the first output end of the sending card 202 is connected to the power supply control module 201, and the second output end is connected to the LED display screen, which is used to send the LED power control signal to the power supply control module 201 according to the received video source signal and control signal, and send the display screen drive signal corresponding to the video source signal to the LED display screen; the power supply control module 201 is also used to control the power on and off of the LED display screen 300 based on the LED power control signal; the LED display screen 300 is used to display the video content of the video source signal.

[0046] In the above embodiment, the first output end and the second output end are different output ports of the control card, and can also be control ports, which can be customized according to specific application scenarios. The output end of the operating system component is connected to the input end of the sending card, and can receive external video source signals and control signals, and output the video source signals and control signals to the sending card. The sending card is connected to the receiving card in the LED display screen, and can send a display drive signal that satisfies the video source signal and the control signal to the receiving card, so that the LED display screen outputs and displays the signal content of the video source signal. The power supply control module can provide direct current and alternating current to the sending card, the LED display screen and the operating system, and at the same time, it can realize the control of power supply. Among them, the control signal is a signal input by the user through a control device such as a tablet computer and a remote control, which is used to control the display of the video source. The operating system component integrates a processor chip and peripheral circuits of the operating system, wherein the operating system can be an Android system, a Windows system, a Hongmeng system or a combination of Android and Windows, and the embodiment of the utility model is not specifically limited. The first control box can be in the form of an independent box body or in the form of a board. The form of an independent box, that is, the operating system component is placed in an independent box, which can be mechanically connected to the all-in-one machine or separated from the all-in-one machine. The form of a board, that is, the operating system component is integrated on the board, and the exposed surface of the board can be covered by the shell of the LED display. By placing the sending card and the operating system component in different control boxes respectively, the second control box where the sending card is located can be set separately in the middle of the LED display, which is convenient for routing to the display areas of the display boxes on both sides, reducing the complexity and length of the routing, and taking up little space, without affecting the beauty of the overall appearance design of the all-in-one machine; at the same time, the first control box where the operating system component is located can be set in a position that does not affect the overall appearance design of the all-in-one machine, such as the back panel of the all-in-one machine or a space independent of the all-in-one machine, so as to avoid affecting the overall appearance design of the all-in-one machine due to its large size, thereby meeting the functional requirements of the all-in-one machine while reducing the constraints and difficulty of the all-in-one machine's appearance design, and improving the freedom of the all-in-one machine's appearance design.

[0047] Working principle: After the power supply control module is powered, it provides AC power to the operating system components and DC power to the sending card so that the operating system components and the sending card can operate normally. The operating system components receive the video source signal and the control signal, and transmit the video source signal and the control signal to the sending card through the interface. The sending card forwards the control signal to the power supply control module so that the power supply control module controls the power on and off of the LED power supply, converts and processes the video source signal, generates a display screen drive signal for driving the LED display screen to display the video screen, and sends the display screen drive signal to the LED display screen so that the LED display screen presents the video source signal content.

[0048] It should be noted that the circuit functions of the integrated machine control architecture provided in this embodiment are mainly realized through the circuit connection relationship between the various circuit modules, and do not rely on the implementation of the program module in a certain circuit module. In addition, each circuit module in the integrated machine control architecture can be realized by an analog circuit or a digital circuit, and for the circuit module that can be implanted with a program module, the realization of its module function can be realized by the program module provided by the prior art.

[0049] The LED all-in-one control architecture proposed in the embodiment of the utility model can split the overall control function module of the all-in-one into two parts through the first control box and the second control box, which can increase the flexibility of shape and position design. At the same time, the power supply control module and the sending card that are closely related to the wiring of the LED display screen are configured in the second control box, which can reduce the complexity of wiring between the modules. The operating system component that occupies a large space is configured in the first control box module, which can reduce the structural constraints of this component on the overall space occupied by the control architecture, thereby reducing the overall space occupation and structural limitations of the control architecture, and improving the freedom of product structure layout and appearance design of the LED all-in-one.

[0050] In one embodiment, Figure 2 As shown, the first control box in the above-mentioned LED all-in-one control architecture is arranged at the lower right corner of the back panel of the LED display screen, and the top and left and right edges of the box body do not exceed the back panel of the LED display screen, and the bottom of the box body does not exceed the bottom of the second control box; the box body of the second control box is arranged in the middle position of the bottom of the LED display screen.

[0051] Specifically, since the operating system components are relatively large in size, the first control box occupies a large space. If it is set inside the visible surface of the all-in-one machine, it will affect the appearance of the product. The first control box does not contain devices that need to be displayed to the user, such as indicator lights indicating the operating status. Therefore, setting the first control box on the back panel of the LED display can reduce the space occupied by the control components on the display surface of the all-in-one machine and improve the aesthetics of the product appearance design. Furthermore, setting the first control box in the lower right corner of the main view of the LED display is ergonomic and convenient for disassembly, assembly and maintenance of the first control box. Since the LED display is composed of multiple display boxes, the sending card needs to be connected to each box. Setting the first control box where the sending card is located in the middle of the bottom of the LED display can shorten and balance the wiring between the sending card and the display box to the greatest extent, reduce the complexity of the wiring, reduce the space occupied by the wiring, and at the same time, improve the operability of the process wiring.

[0052] It should be noted that Figure 2What is shown is only one layout of the control boxes. The present invention does not make any specific limitation on the specific shapes and the size of the space occupied by the first control box and the second control box. For example, the first control box may not be rectangular, but circular or elliptical; the length of the second control box may be less than the length of the bottom edge of the LED display screen or may not be symmetrical about the midpoint of the bottom edge of the LED display screen, etc. The present invention does not make any specific limitation on the embodiments of the present invention.

[0053] In one embodiment, Figure 3 As shown, the first control box in the above-mentioned LED all-in-one control architecture also includes a main switch, and the power supply control module includes a switching power supply module and an up and down power control module; the input end of the switching power supply module and the AC input end of the up and down power control module are respectively connected to the AC power supply through the main switch; the output end of the switching power supply module is respectively connected to the DC input end of the up and down power control module and the power end of the sending card, which is used to convert AC power into DC power and supply DC power to the up and down power control module and the sending card; the AC output end of the up and down power control module is respectively connected to the LED display screen and the operating system component, and the control input end is connected to the first control end of the sending card, which is used to supply power to the LED display screen and the operating system component according to the LED power control signal sent by the sending card.

[0054] Specifically, the total power supply of the LED all-in-one machine is connected to the control circuit through the main switch, and the main switch is used to control the on and off of the total power supply of the LED all-in-one machine. Among them, the main switch can be embedded in the surface of the first control box, or it can be led out of the box body of the first control box through a lead wire. The shape can be a boat-shaped switch, which is not specifically limited in the embodiment of the utility model. When the main switch is in the closed state, 220V AC is connected to the switch power supply module and the upper and lower power control module. The switch power supply module converts the 220V AC into DC power, and provides the DC power to the control unit and the sending card of the upper and lower power control module, so that the upper and lower power control module and the sending card can realize the control function. After the DC power is connected, the sending card generates an LED power control signal according to the control signal, and sends it to the upper and lower power control module, and converts the video source information into a display screen drive signal, and sends it to the receiving card of the LED display screen. When the upper and lower power control module controls the power supply of the LED display screen according to the LED power control signal sent by the sending card, the LED display screen is displayed according to the display screen drive signal when the power is on. Among them, the sending card and the upper and lower power control module can be connected by a flexible flat cable.

[0055] In one embodiment, Figure 3As shown, the second control box in the above-mentioned LED all-in-one control architecture also includes a power amplifier component and a speaker, and the first control box also includes an audio cable; the first end of the audio cable is connected to the operating system component, and the second end of the audio cable is used to connect an external audio device; the third output end of the sending card is connected to the signal input end of the power amplifier component, and is used to transmit an audio signal to the power amplifier component through a digital audio interface standard; the power supply end of the power amplifier component is connected to the DC output end of the up and down power control module, and the output end is connected to the speaker, and is used to control the speaker to play the audio content of the audio signal according to the audio signal.

[0056] Specifically, the power amplifier component is supplied with direct current by the switching power supply module. The sending card communicates data with the power amplifier through SPDIF (Sony / Philips Digital Interface Format, a digital audio interface standard), and uses an asynchronous receiver / transmitter (UART) to transmit audio data. The power amplifier module can also be connected through a soft flat cable to select the working power of the speaker, thereby controlling the audio sound output size. Among them, the number of speakers can be one, two or more. The audio cable can be a lotus head audio cable (RCA: Radio Corporation of America), a 3.5mm audio cable, etc. The embodiment of the utility model does not specifically limit the type of audio cable and the number of speakers. By setting the audio cable in the first control box, the audio cable connection can be hidden when the audio cable is connected to an audio playback device such as an external speaker. In addition, setting the power amplifier component and the speaker in the second control box can not only shorten the wiring length between the power amplifier component and the sending card and the switching power supply module, but also ensure the effect of the speaker playing sound, thereby improving the user experience.

[0057] In one embodiment, Figure 3 As shown, the above-mentioned LED all-in-one control architecture also includes an image acquisition device; the power supply end of the image acquisition device is connected to the AC output end of the upper and lower power control module; the video source output end of the image acquisition device is connected to the serial communication interface of the operating system component, which is used to send the acquired live video source to the operating system component to output and / or transmit the live video source.

[0058] Specifically, the image acquisition device is provided with AC power by the upper and lower power control modules, and can respond to control instructions or collect images or video images in the shooting area in real time, and transmit the collected live video source to the operating system component through the serial communication interface. The operating system component can transmit this live video source to other display terminals or send it to the sending card to display it through the LED display screen of the current all-in-one machine, or it can be sent to the LED display screen and other display terminals of the current all-in-one machine at the same time. For example, in the video conferencing application scenario, this image acquisition device can support video conferencing between the LED all-in-one machine user and other conference members. Among them, the image acquisition device can be a security camera, a medical imaging camera, or an industrial detection camera, etc. The installation position can be a movable device, or it can be installed on the edge of the LED display screen in a fixed or detachable manner. The embodiment of the utility model does not specifically limit the type, fixing method and fixing position of the image acquisition device. By introducing the image acquisition device in the control architecture, the LED all-in-one machine can be applied to more application scenarios and meet more application needs of users, thereby improving the applicability of the product.

[0059] In one embodiment, the operating system component in the above-mentioned LED all-in-one machine control architecture includes a first sending interface and a second sending interface, and the first sending interface and the second sending interface are both embedded with CEC or I2C communication protocols; the first sending interface and the second sending interface are respectively connected to the input end of the sending card, and are used to synchronously or separately send video source signals, audio signals and control signals to the sending card.

[0060] Specifically, the operating system component includes two output interfaces, namely a first sending interface and a second sending interface. The types of these two interfaces are embedded with CEC (Consumer Electronics Control) or I2C (Inter-Integrated Circuit) communication protocols, and the interface type can be HDMI (High Definition Multimedia Interface) or DP (DisplayPort). Among them, the interface types of the two interfaces can be the same or different, and the embedded communication protocol types can be the same or different, and can be customized according to specific application requirements, which is not specifically limited in the embodiments of the utility model. The above two interfaces can select one of them to send the signal through a tablet or a remote control, or two sending interfaces can be used at the same time to send signals synchronously, for example, to realize the application scenario of split-screen display. By introducing two sending interfaces in the operating system component, more selectivity is provided for the use of the all-in-one machine, and at the same time, it is also suitable for more application scenarios.

[0061] In one embodiment, the second control box in the above-mentioned LED integrated machine control architecture also includes a signal source interface; the signal source interface is connected to the operating system component, and is used to receive the video source signal and forward the video source signal to the operating system component.

[0062] Specifically, the signal source interface is set in the second control box, and can be embedded in the box body of the second control box. The signal source interface can be HDMI, which is connected to the operating system component and the video source through an HDMI data cable. By using HDMI as the video source interface, the video source signal transmitted from the video source can be optimized and processed before being transmitted to the operating system component, thereby improving the display effect of the LED display.

[0063] In one embodiment, the second control box in the above-mentioned LED all-in-one control architecture also includes a power button and a status indicator light; the power button is connected to the control end of the sending card to control the display status of the LED display screen; the status indicator light is connected to the fourth output end of the sending card to indicate the operating status of the all-in-one.

[0064] Specifically, the fourth output terminal is one of the multiple output ports of the sending card that is different from the first output port, the second output port and the third output port. The sending card is connected to the status indicator light + button through a flexible cable. When the all-in-one machine is operating normally, short press the power button, the all-in-one machine enters the screen-off state, the sending card controls the screen to be black, and all devices are powered; when the all-in-one machine is operating normally, long press the power button, the all-in-one machine enters the standby state, and the sending card controls the power-on and power-off modules to cut off the power to the screen and the power amplifier. The status indicator light presents different colors when the all-in-one machine is in different operating states of operation, standby and screen-off to indicate the display status of the LED display. By configuring the power button and the status indicator light, different operating states of the all-in-one machine can be controlled and the operating state can be indicated.

[0065] In one embodiment, the LED display screen in the above-mentioned LED all-in-one control architecture includes multiple display boxes, and the display box includes a box power supply, a receiving card and an LED display block; the input end of the box power supply is connected to the AC output end of the power supply control module, and the output end is connected to the LED display block for powering the LED display block; the input end of the receiving card is communicatively connected to the sending card, and the output end is connected to the LED display block for receiving the control signal sent by the sending card, and forwarding the control signal to the LED display block to control the LED display block to display the corresponding area screen in the video content of the video source signal.

[0066] Specifically, the LED display screen includes multiple display boxes, and the number of display boxes depends on the resolution and dot pitch of the display screen. For example, if the display screen has a dot pitch of 0.7mm and a resolution of 4K, the display boxes are arranged in a 5*5 matrix; if the display screen has a dot pitch of 1.2mm and a resolution of 2K, the display boxes are arranged in a 4*4 matrix.
