[0038] In order to enable a person skilled in the art to more fully understand the features and technical contents of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the drawings, which are only used for reference and are not intended to limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, through multiple details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0039] The terms "first", "second", and the like in the embodiments of the present disclosure are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so as to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0040] Unless otherwise specified, the term "a plurality of" means two or more.

[0041] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0042] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three relationships.

[0043] The term "corresponding" can refer to an association or binding relationship. A and B correspond to each other means that A and B have an association or binding relationship.

[0044] The monopoly of high-end electronic components (such as CPU, SoC) abroad directly restricts the development of China's electronic information industry. For example, if the core chip relies on import, once it encounters technical restrictions, it may lead to equipment shutdown, data security threats, and even threats to the national economy and national security. Realizing the localization of electronic components has great practical significance and is the key to breaking free from being controlled by others. In the CPU field, domestic chip manufacturers such as Loongson, Feiteng, and Shenwei have also launched various self-controllable domestic CPU chipsets, based on which domestic servers and other related products have also developed rapidly. In addition, in the SoC field, chip manufacturers such as HiSilicon, Ruijie Micro, and Allwinner have also launched various self-controllable domestic SoCs. However, in the field of intelligent interactive terminals, there are still deficiencies in realizing nationalization and perfecting the functions of the products. The existing interactive terminals need to be improved in terms of self-controllability, interface richness, storage security, and portability, and it is difficult to meet the intelligent control and interaction needs of multiple scenarios such as manufacturing, logistics, and medical treatment.

[0045] To solve the above problems, the present embodiment provides a nationalized interactive terminal. The nationalized interactive terminal provided by the present embodiment will be described in detail below in conjunction with the drawings.

[0046] Figure 1 is a system block diagram of a nationalized interactive terminal provided by the present embodiment. In combination with Figure 1 , the nationalized interactive terminal includes a mainboard module, and a touch display module, a power supply module, a camera module, an interface module, a sound module, and a key indicator light, etc. in communication connection with the mainboard module. The interactive terminal developed by the present embodiment has computing function, display function, data forwarding function, data processing function, etc. All components in the above-mentioned modules are selected from domestic components, so as to achieve full-link replacement of domestic chips, reduce dependence on external technology, meet the demand of national information security strategy, and have significant social benefits.

[0047] The following describes each module in the nationalized interactive terminal.

[0048] Figure 2 is a framework diagram of a mainboard module provided by the present embodiment. Referring to Figure 2The mainboard module includes a processor, and a memory, a storage chip, an electronic disk, a single-chip microcomputer, a network chip and an audio codec chip connected in communication with the processor. In the application, the processor can be selected as an RK3588 SOC (System-on-a-Chip), the RK3588 SOC integrates various functional interfaces, is responsible for data processing and coordination of various modules, is a hardware interaction core hub, and all peripheral modules transmit and exchange data around it. The RK3588 adopts a quad-core ARM Cortex-A76 and a quad-core ARM Cortex-A55 big core architecture, has strong computing and multi-threaded processing capabilities, and low energy consumption. The RK3588 has a built-in 6TOPS computing power NPU, supports various deep learning frameworks, and has excellent AI computing capability. At the same time, the RK3588 has strong 8K high-definition video encoding and decoding capability, and can realize multi-screen heterogeneous display. In addition, the RK3588 has rich interfaces, including PCIe 3.0, USB3.0 and other high-speed interfaces, and has strong data communication and peripheral expansion capability. Moreover, the RK3588 supports various operating systems, can be remotely upgraded and managed, and has industrial-grade quality and can adapt to harsh environments.

[0049] In some embodiments, the memory is two 4GB LPDDR4X memory particles connected in parallel with the processor through a DDR PHY channel. Figure 2 In some embodiments, the mainboard module integrates two groups of LPDDR4 Memory Down 4GB connected to the RK3588 through LPDDR4 Channel 0 / 1 to provide high-speed cache for system operation, guarantee fast data read and write, and support efficient system operation. Figure 3 is a memory design block diagram provided by an embodiment of the disclosure. In combination with Figure 3 The RK3588 integrates two LPDDR4X 4GB (Low-Power Double Data Rate 4X, fourth generation low-power double data rate synchronous dynamic random access memory) through DDR PHY CH0 / CH1 (DDR physical layer channel 0 / channel 1), and the total capacity is 8GB, which guarantees efficient processing of data by the RK3588.

[0050] In some embodiments, the storage chip includes an embedded multi-media card (Embedded Multi-Media Card, eMMC) and an M.2 electronic disk, the eMMC 256GB is connected to the RK3588 through an eMMC5.1 interface, and is used for storing systems, applications and the like, the M.2 electronic disk is connected to the RK3588 through a PCIe3.0 interface, the M.2 electronic disk can be used as a large-capacity storage expansion, such as storing large amounts of data and large applications, and supports software-triggered data soft destruction function.

[0051] The display screen is connected to the RK3588 through a dual-MIP IDSI interface. MIP IDSI (Mobile Industry Processor Interface-Display Serial Interface) is a mobile device display interface standard, which realizes high-definition image transmission to enable the AMOLED display screen to present high-quality display effects (such as high contrast and wide color gamut). The touch screen is connected to the GPIO:I2C_0 of the RK3588 through an I2C (Inter-Integrated Circuit) interface, which realizes touch signal transmission and enables the device to support touch interaction.

[0052] The rear camera in the camera module is connected to the MIP IDPHY RX 8CH of the RK3588 through an MIPI_CSI interface. The MIPI_CSI interface can transmit the captured image data to the RK3588 for processing, which is used for photographing and video recording functions.

[0053] The PCIe3.0x4 PHY output of the RK3588 is connected to the network chip through a PCIe2.0 interface, and then connected to the external interface through a gigabit network port, which realizes network data transmission and reception, enabling the device to connect to a wired network and perform network communication.

[0054] The HDMI2.1 TX / eDP1.3 of the RK3588 is converted to HDMI1, which is used for external display, television, etc. to output high-definition video. The USB3.0 or USB2.0 interface is connected to the docking station, which can convert multiple USB2.0 interfaces to connect U disks, mice, keyboards, and other peripherals, expanding the device connection capability. The GPIO:UART of the RK3588 is connected to the level conversion through UART4, and then converted to RS2322 and RS485, which is used for device debugging and communication with industrial devices or traditional modules. The level conversion realizes the conversion between different level standards (such as TTL level and RS232, RS485 level), enabling devices with different level requirements to communicate.

[0055] The RK3588 is connected to the audio codec chip through GPIO:I2S (audio serial transmission interface) and GPIO:I2C_3 (controls the audio codec chip). The audio codec chip is responsible for audio encoding and decoding, and then through the power amplifier (Power Amplifier) to drive the speaker to sound, and through the microphone to collect sound, realizing sound input and output, such as recording, playing music or voice.

[0056] In some embodiments, the power supply module includes a built-in battery and a power switching circuit, wherein the power switching circuit is connected to both an external power source and the built-in battery. The power switching circuit uses a switching chip to automatically select between the external power source and the built-in battery. The selection logic prioritizes using a higher voltage power source to supply power to the system power supply. When the external power source is supplying power, a charging chip simultaneously controls the external power source to charge the built-in battery.

[0057] Figure 4 This is a design block diagram of a power switching embodiment provided in this disclosure, such as... Figure 4 As shown, the power adapter converts AC mains power (such as household 220V AC) into DC power usable by the device. A DC-DC isolation module disconnects the direct electrical connection between input and output, ensuring interference resistance and safety, and outputs a stable 15V DC power to power the charging chip and switching chip. Here, the power adapter's input range is AC 190V–240V, and the output voltage is DC 24V. The DC-DC power module's operating voltage range is DC 18V–30V. The charging chip receives the 15V DC power from the DC-DC isolation module and is specifically responsible for charging the built-in battery. It converts and regulates the charging current / voltage according to the battery's needs (e.g., lithium batteries require constant current and constant voltage charging), ensuring safe and efficient battery charging and preventing overcharging or undercharging damage. The built-in battery stores electrical energy and can power the motherboard system when the battery is depleted, enabling portable, offline use of the device. Figure 4 The built-in battery serves as both the charging source for the charging chip and a power source for the switching chip. The switching chip intelligently selects the power source, prioritizing the higher voltage output to the motherboard system from either the power adapter (15V after DC-DC isolation) or the built-in battery (voltage range 7.5V–15V, varying with battery level), ensuring continuous and stable power supply to the motherboard. When external power is unavailable, the switching chip seamlessly switches to the remaining power source, the built-in battery, to power the motherboard system. Therefore, the motherboard system's power supply (Vadp) is a dynamic voltage ranging from 7.5V to 15V, with each subsystem performing DC-DC level conversion based on this voltage to achieve the desired power supply design.

[0058] In some embodiments, the charging chip controls the charging process of the built-in battery through a three-stage charging mode, including a trickle charging stage, a constant current charging stage, and a constant voltage charging stage. Specifically, when the built-in battery voltage is low and in an over-discharged state, trickle charging is used to charge the battery to a suitable voltage. Then, a constant current (0.5C) charging method is used to quickly charge the built-in battery until it is nearly fully charged. Finally, a constant voltage charging method is used to supplement the constant current charging, and charging stops when the charging current is less than 1 / 25 of the maximum charging current. This avoids shortening the lifespan of the lithium battery due to increased charging current.

[0059] In some embodiments, the charging chip is integrated with a temperature monitoring unit through the single-chip microcomputer, that is, a charging monitoring circuit is added through the single-chip microcomputer. When the temperature of the built-in battery is lower than a preset threshold, a large-current charging mode is adopted; when the temperature of the built-in battery is higher than the preset threshold, a small-current charging mode is adopted; and when the temperature of the built-in battery is higher than an allowed maximum working temperature, charging is suspended, and charging is resumed after the built-in battery is cooled. In this way, an additional protection layer is added outside the self-protection of the built-in battery, the reliability is improved, and the service life of the built-in battery is also prolonged.

[0060] In some embodiments, the EC design can be implemented by using the GD32F103TBU6 single-chip microcomputer of GigaDevice. The chip is based on the ARM Cortex-M3 core, and the main frequency can reach 72 MHz. The operation performance is excellent and the power consumption is low, which is suitable for the EC scenario of long-term operation. The rich peripheral interface (such as 3 USARTs, 2 SPIs, and 2 I2Cs) can flexibly connect peripheral devices such as temperature sensors and power management ICs, meeting the needs of the EC for multi-device management. The built-in 12-bit ADC can accurately collect analog signals such as voltage and temperature, and cooperate with the timer to realize PWM output control of fan speed or power timing. In addition, the chip supports 5V tolerant input, has strong anti-interference ability, and has reset and power failure detection functions, which can effectively guarantee the stable operation of the system in complex environments.

[0061] In some embodiments, the mainboard module further includes a clock chip, which provides a 100MHz synchronous clock signal to the processor, the electronic disk and the network chip. Figure 5 is a main clock design block diagram provided by an embodiment of the disclosure. As shown in Figure 5 , a 24MHz passive crystal oscillator provides a low-speed, basic clock reference for the system, which is commonly used as a clock source for some peripherals and low-speed functions. A 100MHz active crystal oscillator serves as a high-speed, accurate clock source to provide signals for modules with high clock requirements. The clock chip can be selected as the GM50301 chip. The GM50301 clock buffer is used to receive the clock signal of the 100MHz active crystal oscillator, shape the signal, enhance the driving capability, and then distribute multiple 100MHz clock signals at the HCSL (High-Speed Current-Steering Logic) level to ensure the synchronization and stability of the clock of multiple modules and avoid signal attenuation affecting the operation of the system.

[0062] In some embodiments, the network chip is connected with the processor through a PCIe interface, outputs three 10G network signals, and transmits the signals to the outside through the 10G network port after enhancement by a network transformer. Figure 6 is a network design block diagram provided by an embodiment of the disclosure. As shown in Figure 6, RK3588 as the main control, the system data is transmitted to the network chip WX1860AL4 through PCIe3.0, and the network chip supports 4-way gigabit network output. The network chip WX1860AL4 receives the data transmitted by RK3588 through PCIe, performs network protocol processing (such as TCP / IP analysis), data forwarding, etc., and converts the system data into a network transmissible format. The network transformer SG24002T is used for signal isolation, filtering, impedance matching, isolation of external network interference signals, protection of internal circuits of the device, filtering of noise, making the network signal purer, matching the impedance of different devices, and ensuring stable signal transmission. After the system data is purified by the network transformer, it is connected to the external network through 3-way gigabit network interface, realizing high-speed wired networking of the device. At the same time, when the external network data is transmitted reversely, it is transmitted to RK3588 through the gigabit network interface, the network transformer network chip and PCIe in turn, and the data is transmitted back to the processor for processing.

[0063] In some embodiments, the audio codec chip is connected with the processor through an I2S interface, and the audio signal paths of the built-in microphone, the built-in speaker and the voice interface are switched through a multiplexer. Figure 7 is an audio implementation design block diagram provided by an embodiment of the present disclosure. Referring to Figure 7 , RK3588 as the main control, configures the audio codec chip through I2C_3 (control bus), and sends control instructions (such as setting volume, sampling rate) to the audio codec chip, realizing configuration and state reading of the audio codec chip. RK3588 transmits digital audio (such as played music, collected voice) through I2S_0 (audio data bus), ensuring high-quality and low-delay transmission of audio. The audio codec chip is used for encoding (such as converting the analog sound collected by the microphone into a digital signal) and decoding (such as converting the digital audio back to analog sound to the speaker) of the audio signal. The audio codec chip is connected with the built-in microphone, the built-in speaker and the external voice interface through MUX (Multiplexer), realizing local and external audio input and output, supporting functions such as recording, playing and voice interaction of the device.

[0064] In some embodiments, the interface module serves as the core hub of the device connected to the outside, providing a variety of interface resources to meet the needs of data transmission, device connection and function expansion in different scenarios. The interface module includes one power interface, three network interfaces, two USB interfaces, one voice interface, two RS232 interfaces, two RS485 interfaces, one HDMI+USB interface, etc. Specifically, the network interfaces are all gigabit network interfaces, supporting 10 / 100 / 1000 Mbps adaptive transmission rate and full-duplex communication mode, suitable for high-bandwidth scenarios such as high-definition video monitoring and industrial Internet of Things data acquisition. The USB interface conforms to the USB 2.0 / 3.0 standard protocol and has hot-plug characteristics, seamlessly compatible with input devices such as USB mouse and keyboard, meeting the needs of human-computer interaction; it also supports storage devices such as USB flash drives and mobile hard drives, facilitating fast copying and storage of data; in addition, it can also adapt to USB optical drives, facilitating system installation and software upgrades. The voice interface connects the earphone to realize voice input and output, suitable for voice interaction, remote conference and other scenarios. The RS232 interface is commonly used to connect serial printers, industrial control devices, etc., facilitating device debugging and instruction transmission; the RS485 interface uses differential signal transmission and has strong anti-interference ability, supporting half-duplex communication and realizing long-distance data transmission up to 1200 meters, easily forming a multi-node industrial control network, suitable for building automation, power monitoring and other fields. The HDMI+USB composite interface integrates 1-way HDMI high-definition video output and 1-way USB data transmission function. Among them, the HDMI interface supports ultra-high-definition video output, which can clearly project the device screen to display terminals such as monitors and projectors, suitable for conference display, home theater and other scenarios; the USB interface can connect external devices such as cameras and microphones, further expanding device functions.

[0065] In some embodiments, the touch display module provides display, touch control or stylus operation, including a display touch screen supporting multi-point touch control function. The display touch screen is an AMOLED screen with a resolution not less than 2560x1536 and supports multi-point touch control operation with an embedded touch pen. The touch display module uses the 3D graphics processor built in the processor as the whole machine graphics card to drive the AMOLED screen display.

[0066] In some embodiments, the camera module includes a camera and a flash. The camera selects a 500W pixel camera with a MIPI interface, and the rear camera is equipped with a constant-current flash, which can meet the needs of high-quality camera and shooting functions in multiple scenarios.
