[0030] The interactive screen has multiple functional modules inside, such as a microphone module and a speaker module. When connecting functional modules inside the interactive screen in related technologies, the relevant functional modules are generally connected to the motherboard by independent signal lines. During the assembly process, the interactive screen has too many wiring harnesses, which makes assembly inconvenient.
[0031] Based on the above problems, the networking system provided in this application includes a motherboard, multiple first signal conversion modules, and multiple first functional modules. Each first signal conversion module corresponds one-to-one with a first functional module, and each first signal conversion module is electrically connected to its corresponding first functional module. All first signal conversion modules are electrically connected via a target cable, and all first signal conversion modules are identical. Since each first signal conversion module can convert the signal output by its corresponding first functional module into a first target signal corresponding to the protocol of the target cable, the first target signals output by all first signal conversion modules conform to the protocol corresponding to the target cable. This enables communication between all first signal conversion modules and between all first signal conversion modules and the motherboard using a single target cable. Compared to existing interactive large screens where each functional module needs a separate signal cable to connect to the motherboard, the networking system provided in this application uses a target cable to achieve connection and communication between the first signal conversion modules and the motherboard, greatly saving wiring and facilitating assembly.
[0032] To illustrate the technical solution described in this application, specific embodiments are provided below.
[0033] Figure 1 A schematic block diagram of a networking system according to an embodiment of this application is shown. See also... Figure 1 As shown, the networking system includes a motherboard 101, multiple first signal conversion modules 102, and multiple first functional modules 103. Each first signal conversion module 102 and each first functional module 103 corresponds one-to-one. Each first signal conversion module 102 is electrically connected to its corresponding first functional module 103. Each first signal conversion module 102 is electrically connected to a target cable and, through the target cable, to the motherboard 101. The first signal conversion modules 102 are identical to each other.
[0034] Specifically, since the first signal conversion module 102 can convert the signal output by the corresponding first functional module 103 into a first target signal corresponding to the protocol of the target cable, all the first target signals output by the first signal conversion modules 102 conform to the protocol corresponding to the target cable. This enables communication between the first signal conversion modules 102 and between all the first signal conversion modules 102 and the motherboard 101 through the use of the target cable. Compared with the connection method in related technologies where each functional module needs to be connected to the motherboard 101 separately using a signal cable when connecting interactive large screen functional modules, the networking system provided in this application uses the target cable to realize the connection and communication between the first signal conversion module 102 and the motherboard 101, which greatly saves wiring and facilitates assembly.
[0035] It should be noted that in existing interactive large screens, each functional module requires a separate signal cable to be connected to the motherboard 101, which causes signal mixing within the wiring harness and affects the data communication quality between the functional modules and the motherboard 101. However, the networking system provided in this application uses a target cable to achieve connection and communication between the first signal conversion module 102 and the motherboard 101, which can greatly improve the data communication quality between the functional modules and the motherboard 101.
[0036] It should be noted that the target cable is a twisted-pair cable. Twisted-pair cables, by twisting two conductors together in a spiral, effectively reduce electromagnetic interference and radio frequency interference, thereby improving the stability and reliability of signal transmission. Furthermore, twisted-pair cables can maintain high-quality signal transmission over long distances, and their lower manufacturing cost reduces the design cost of interactive screens.
[0037] It's worth noting that the protocol used with the twisted-pair cable is A2B (Automotive Audio Bus). The A2B bus protocol, when used with twisted-pair cables, supports data transmission rates up to 50Mbps, enabling the transmission of high-quality audio data to meet the needs of high-resolution audio applications. Furthermore, the A2B bus is designed for real-time audio transmission, featuring very low latency to ensure the real-time performance and synchronization of audio signals. In addition, the A2B bus can use a single twisted-pair cable to transmit audio data and control signals, while also supporting power supply, further reducing the number of cables and simplifying wiring.
[0038] In one embodiment of this application, the first signal conversion module 102 includes a signal processor and a protocol converter. The signal processor is connected between the first functional module 103 and the protocol converter, and the protocol converter is connected between the signal processor and the target cable.
[0039] Specifically, the signal processor receives the raw signal output from the first functional module 103 and processes and optimizes it. This includes signal amplification, encoding, filtering, and noise suppression to ensure high-quality signal transmission. Furthermore, the signal processor can convert signals of different formats into a unified format for subsequent protocol converter processing. For example, it can convert analog signals to digital signals or unify digital signals with different encoding formats into a standard format. The protocol converter converts the signal processed by the signal processor into a first target signal corresponding to the protocol of the target cable. For example, it converts the processed digital signal into a first target signal conforming to the A2B bus protocol. The protocol converter can also adapt to different communication standards and interfaces to ensure correct signal transmission on the target cable. For example, it can perform voltage level conversion and signal timing adjustment.
[0040] For example, the signal processor could be the Analog Devices ADAU1452, and the protocol converter could be the Analog Devices ADM3053. Both the ADAU1452 and ADM3053 are highly integrated chips, reducing the number of external components and simplifying circuit design. The ADAU1452 supports complex audio processing algorithms, ensuring audio quality; the ADM3053 supports the A2B bus protocol, providing efficient and reliable audio transmission. Designers can also select appropriate chip models for the signal processor and protocol converter based on actual needs to ensure that their functions and performance meet system requirements. No specific model of chip is limited here.
[0041] In one embodiment of this application, the first functional module 103 is any one of the following modules: a first sensor module, a first microphone module, a first audio module, a first display module, and a first switch module. Figure 2 As shown, taking the counterclockwise direction as an example, the first functional module 103 consists of the first sensor module, the first microphone module, the first audio module, the first display module, and the first switch module in sequence.
[0042] Specifically, the first sensor module is used to detect environmental parameters such as temperature, humidity, and light intensity. It can also be used for user interaction, such as detecting user gestures and touches. The first sensor module can also monitor the status of the interactive screen, such as whether it has been moved or experiencing abnormal vibrations. The first microphone module is used to capture user voice commands for voice recognition and interaction, and also detects environmental noise for noise reduction. The first microphone module may include a microphone. The first speaker module can play audio content such as music, voice prompts, and notifications. It can also perform sound effects processing, such as equalization and stereo expansion, to provide high-quality audio output. The first speaker module may include speakers or loudspeakers. The first display module is used to display images, lights, and video content, providing visual information. It can also support touch input, providing interactive functions. The first display module may include indicator lights, a display screen, etc. The first switch module is used to control the power switch of the interactive screen, enabling it to be turned on and off. The first switch module may include a switch button.
[0043] For example, multiple first microphone modules and multiple first speaker modules can be set, such as two first microphone modules and two first speaker modules. Both the two first microphone modules and the two first speaker modules are connected to the motherboard 101 via twisted-pair cables to achieve connection and communication with the motherboard 101. Setting multiple first microphone modules enables sound source localization, improving the accuracy of speech recognition. Setting multiple first speaker modules supports multi-channel audio output, providing a rich audio experience.
[0044] In one embodiment of this application, such as Figure 3 As shown, the motherboard 101 includes a control chip and a second signal conversion module 104. The second signal conversion module 104 is electrically connected to the control chip and is electrically connected to all the first signal conversion modules 102 through a target cable.
[0045] Specifically, the control chip can output audio signals or I2C control signals. The second signal conversion module 104 receives the audio signals or control signals output by the control chip, encodes them, and outputs a second target signal corresponding to the protocol of the target cable (twisted pair). That is, both the second signal conversion module 104 and the first signal conversion module 102 can convert the input signal into a target signal corresponding to the protocol (A2B bus) of the twisted pair.
[0046] It should be noted that the second signal conversion module 104 may also include a signal processor and a protocol converter. The signal processor is connected between the control chip and the protocol converter, and the protocol converter is connected between the signal processor and the target cable. The signal processor receives the control signal output by the control chip and encodes it. The protocol converter converts the signal encoded by the signal processor into a second target signal corresponding to the protocol of the target cable. For example, it converts the encoded control signal into a second target signal conforming to the A2B bus protocol.
[0047] It should be noted that the first signal conversion module 102 is also used to decode the second target signal output by the second signal conversion module 104 after receiving it, and extract audio data or I2C (Inter-Integrated Circuit) control data, so that the corresponding first functional module 103 can perform the corresponding functional operation.
[0048] It should be noted that the first target signal output by the first signal conversion module 102 may include the working status and feedback data of the corresponding first functional module 103. The second signal conversion module 104 can receive the first target signal output by the first signal conversion module 102, decode it, and transmit it to the control chip. The second target signal output by the second signal conversion module 104 may include control commands and configuration parameter information, etc. Through the coordinated action of the first signal conversion module 102 and the second signal conversion module 104, bidirectional communication between all first functional modules 103 and the control chip on the motherboard 101 is achieved.
[0049] It should be noted that in the prior art, all functional modules are individually connected to the control chip inside the motherboard 101 using signal lines, resulting in excessive wiring and inconvenience for assembly. In contrast, the networking system of this application can achieve bidirectional communication between multiple first functional modules 103 and the motherboard 101 using only twisted-pair cables, greatly saving on wiring.
[0050] For example, the control chip can be a highly integrated integrated circuit, such as a SOC (System on a Chip) chip.
[0051] In one embodiment of this application, such as Figure 3 As shown, the motherboard 101 also includes a power module, which is electrically connected to the second signal conversion module 104 and is used to output power voltage.
[0052] Specifically, the power module is electrically connected to the second signal conversion module 104, meaning the power module can supply power to all the first functional modules 103 within the interactive screen via twisted-pair cables. In the prior art, supplying power to functional modules requires adding at least two additional data cables; this application saves on the number of cables by sharing twisted-pair cables with the power module.
[0053] In one embodiment of this application, such as Figure 4 As shown, the networking system also includes multiple third signal conversion modules and multiple second function modules 105. The multiple third signal conversion modules and the second function modules 105 correspond one-to-one. Each third signal conversion module is electrically connected to its corresponding second function module 105. All third signal conversion modules are electrically connected through target cables. All third signal conversion modules are electrically connected to the motherboard 101 through target cables. All third signal conversion modules are identical.
[0054] Specifically, since the third signal conversion module can convert the signal output by the corresponding second functional module 105 into a third target signal corresponding to the protocol of the target cable, the third target signals output by all third signal conversion modules conform to the protocol corresponding to the target cable. This enables communication between all third signal conversion modules and between all third signal conversion modules and the motherboard 101 using a single target cable. The networking system provided in this embodiment uses a single target cable to achieve connection and communication between all third signal conversion modules and the motherboard 101, saving on cabling and avoiding the need for multiple interfaces when expanding external modules.
[0055] It should be noted that the third signal conversion module may also include a signal processor and a protocol converter. The signal processor is connected between the second functional module 105 and the protocol converter, and the protocol converter is connected between the signal processor and the target cable. The signal processor receives the raw signal output from the second functional module 105 and processes and optimizes it. The protocol converter converts the signal processed by the signal processor into a third target signal corresponding to the protocol of the target cable. For example, it converts the encoded signal into a third target signal conforming to the A2B bus protocol.
[0056] In one embodiment of this application, the second functional module 105 is any one of the following modules: a second sensor module, a second microphone module, a second audio module, a second display module, and a second switch module. Figure 5 As shown, from left to right on the outside of the interactive large screen, the second functional module 105 consists of the second sensor module, the second microphone module, the second speaker module, and the second switch module.
[0057] Specifically, the second sensor module is used to detect environmental parameters such as temperature, humidity, and light intensity. It can also be used for user interaction, such as detecting user gestures and touches. The second microphone module is used to capture user voice commands for voice recognition and interaction, and to detect environmental noise for noise reduction. The second microphone module may include a microphone. The second speaker module can play audio content such as music, voice prompts, and notifications. It can also perform sound effects processing, such as equalization and stereo expansion, to provide high-quality audio output. The second speaker module may include speakers or loudspeakers. The second switch module is used to control the power switch of the interactive screen, enabling the interactive screen to be turned on and off. The second switch module may include a switch button.
[0058] For example, multiple second microphone modules and multiple second speaker modules can be set, such as two second microphone modules and two second speaker modules. Both the two second microphone modules and the two second speaker modules are connected to the motherboard 101 via twisted-pair cables to achieve connection and communication with the motherboard 101.
[0059] This application also discloses an interactive large screen, including the aforementioned networking system. The interactive large screen, employing this networking system, can efficiently transmit data with all functional modules, enabling collaborative work among multiple devices and improving user experience. Furthermore, by using the aforementioned networking system, devices can be added or removed as needed to adapt to the requirements of different application scenarios.
[0060] This application also discloses an electronic device, including the aforementioned interactive screen. The electronic device using the aforementioned interactive screen can provide a richer and more intuitive user interface, thereby improving the user's operating experience and satisfaction.
[0061] Since the processing and functions implemented by the interactive screen and electronic device in this embodiment are basically the same as the embodiments, principles and examples of the aforementioned networking system, any details not covered in this embodiment can be found in the relevant descriptions in the aforementioned embodiments, and will not be repeated here.
