[0053] The routing processing module is used for providing wireless network access and multi-port data exchange functions;

[0054] The master processing module generates control instructions, and the routing processing module executes network strategies based on the control instructions.

[0055] As shown in the accompanying drawings, Figure 1 An apparatus integrating cloud computer and wireless routing functions adopts a master-slave control structure and is composed of a master processing module, a routing processing module, a network interaction module, a power management module, and other auxiliary modules.

[0056] The master processing module adopts a Rockchip RK3566 quad-core processor as a core controller, is used for receiving video stream data from a cloud server, and performs decoding, rendering, and processing of local user interaction logic. The module is connected with a display interface (such as HDMI) to drive an external display, and is also connected with a USB expansion module for accessing keyboards, mice, memories, and other peripherals. The master processing module is embedded with a network protocol stack to perform data communication and instruction interaction with the routing processing module through an Ethernet port.

[0057] The routing processing module is constructed based on a Mediatek MT7918BA wireless communication suite, internally integrates an MT7976CN WiFi6 chip and an MT7531AE gigabit switching chip, and is used for realizing wireless access point (AP) and local area network switching functions. The gigabit switching chip provides an uplink WAN interface and multiple downlink LAN interfaces, and supports access of multiple terminal devices. The WiFi chip supports 2.4 GHz and 5 GHz dual-band wireless access, and conforms to the IEEE 802.11ax standard.

[0058] The network interaction module comprises a physical layer connection and protocol conversion unit, adopts a gigabit Ethernet PHY chip to build a connection channel between master and slave devices, and completes ARP address resolution and VLAN isolation through a protocol adaptation layer, so as to ensure that the data link between the master module and the routing module is stable and reliable.

[0059] The power management module is used for supplying power to various processing modules inside the device. The module comprises a DC-DC step-down circuit, an overload protection unit and a state feedback circuit, can convert the 12V power input from outside into multiple voltages such as 5V and 3.3V, and supply them to the master control processing module, the routing processing module and the peripheral circuit respectively. In order to improve the stability of the system, the power management module monitors the output current of each channel, and automatically cuts off the corresponding circuit when an abnormality occurs, so as to avoid damage to the system.

[0060] In the specific control process, the master control processing module serves as the system master control end, is responsible for generating global control instructions such as WiFi switch and device access strategy configuration, and sends them to the routing processing module through the network interaction module. The routing processing module serves as the slave control end, responds to the master control instructions to execute the network strategy, and feeds back the current running state (such as the connected device list and the bandwidth occupation situation) to the master control module. The master control processing module can further generate a management interface or a state prompt on the display interface for the user to view and adjust.

[0061] Further, the master control processing module comprises a quad-core processor, and the quad-core processor is connected with a display interface module.

[0062] The quad-core processor is configured to receive picture data compressed from a video stream, and output the video stream data to a display device through the display interface module.

[0063] Meanwhile, the quad-core processor communicates and interacts with the routing processing module through a network protocol stack.

[0064] In one specific embodiment of the application, the master control processing module comprises a quad-core processor, which is used for executing core operation tasks related to the cloud terminal function. The quad-core processor can be a multi-core SoC chip based on the ARM Cortex-A55 architecture, and has strong multimedia processing and data communication capabilities.

[0065] The quad-core processor is connected to the display interface module through the integrated display control unit thereof, the display interface module can adopt an HDMI standard interface, and is configured with a TMDS differential output channel to realize video signal transmission to an external display device. An EDID information storage unit is embedded in the display interface module, which is used for providing identification and resolution configuration parameters of the display device.

[0066] In actual operation, the quad-core processor is configured to receive video stream data from a cloud server, the video data being pre-compressed and encoded via a remote server, transmitted to a local and then decoded and rendered by the processor.

[0067] In addition, the quad-core processor is integrated with a network protocol stack for supporting a TCP / IP protocol family and establishing a communication link with a routing processing module through the network interaction module to implement instruction issuing and state feedback on network configuration, data forwarding strategy and the like, thereby ensuring collaborative operation between the master processing module and the routing processing module.

[0068] Through the above structural configuration, the master processing module can complete video stream access, processing and output from a cloud platform to a user terminal and realize unified control on a network environment through instruction interaction with the routing processing module.

[0069] Further, the network interaction module comprises a physical layer connection channel and a protocol conversion layer.

[0070] The physical layer connection channel connects the master processing module and the routing processing module through a gigabit Ethernet interface.

[0071] The protocol conversion layer is used to implement address resolution protocol and virtual local area network isolation.

[0072] In a preferred embodiment of the present application, the network interaction module comprises a physical layer connection channel and a protocol conversion layer, configured to establish a high-speed data communication channel between the master processing module and the routing processing module.

[0073] The physical layer connection channel is composed of a gigabit Ethernet PHY chip, which is connected with Ethernet MAC controllers of the master processing module and the routing processing module through high-speed serial MII or RGMII respectively.

[0074] The protocol conversion layer is integrated in internal control logic of the master processing module and the routing processing module or set as an independent embedded protocol processing unit, used to implement interactive control of network layer and link layer protocols.

[0075] In addition, the protocol conversion layer also supports virtual local area network (VLAN) isolation, which is used to divide different logical subnet segments within the system, limit the scope of broadcast domains, and improve data isolation and communication security. This layer can perform tag insertion, forwarding, and filtering based on the IEEE802.1Q standard, thereby achieving logical separation of communication between the main control module and the routing module.

[0076] Through the structural design of the above-mentioned network interaction module, stable high-speed data interconnection can be achieved between the main control processing module and the routing processing module, and the reliable exchange of control instructions and status information can be supported through the protocol layer, providing the necessary communication basis for collaborative control under the master-slave architecture.

[0077] Furthermore, the routing processing module includes a main control chip, a WiFi chip and a gigabit switching chip;

[0078] The gigabit switching chip is used to provide an uplink network interface and multiple downlink network interfaces;

[0079] The WiFi chip supports the WiFi6 standard and provides wireless access functions in the 2.4GHz and 5GHz frequency bands.

[0080] like Figure 2 and Figure 3 As shown, Figure 3 This is a schematic circuit diagram of the routing processing module provided in an embodiment of the present application. In one embodiment of the present invention, the routing processing module is built on the basis of MediaTek's wireless network processing chip suite, including a main control chip, a WiFi chip, and a gigabit switching chip, which respectively undertake network protocol control, wireless communication, and multi-port Ethernet switching functions.

[0081] The main control chip can be the MT7918BA, which features a high-performance dual-core processor and network protocol stack. It supports routing modules such as NAT, DHCP, port mapping, and QoS. It parses and executes network control commands sent by the main control processing module, while also providing feedback on network status. The main control chip connects to the WiFi chip and switch chip via a local SPI bus or PCIe interface, managing their scheduling.

[0082] The Wi-Fi chip can be the MT7976CN or a functionally equivalent chip, supporting wireless communications compliant with the IEEE 802.11ax (Wi-Fi 6) standard, providing 2.4GHz and 5GHz dual-band channels, and supporting MIMO (Multi-Input Multiple-Output) technology for high-speed, low-latency wireless access. The Wi-Fi chip connects to an external antenna and is equipped with a front-end RF module (FEM) to enhance signal transmission and reception performance.

[0083] The gigabit exchange chip is, for example, MT7531AE, supports one uplink WAN interface and multiple downlink LAN interfaces, and the specific number can be configured as four, five or other structures according to requirements. The chip internally supports IEEE 802.1Q VLAN tagging, 802.3x flow control and hardware QoS scheduling, realizes data forwarding, broadcast suppression and bandwidth allocation control of local area network terminal devices. The uplink port can be connected to the external broadband access port, and the downlink port is used to access wired terminal devices such as PC, printer and the like.

[0084] The above-mentioned master control chip, WiFi chip and exchange chip are connected and cooperated through high-speed inter-chip interface (such as RGMII, MDIO, GPIO), together constitute a complete routing processing module, and through the network interaction module and the master control processing module, a data link is established, so that the wireless and wired network services are provided under the unified control.

[0085] Further, the device further comprises an interface switching module connected with the master control processing module and the routing processing module respectively, for generating a floating control on the display device and realizing switching between the cloud computer operation interface and the router management interface;

[0086] The router management interface is used to present network status, device access and bandwidth management information.

[0087] In an embodiment of the present application, the device further comprises an interface switching module connected with the master control processing module and the routing processing module respectively, for realizing switching control of the two user interfaces.

[0088] The interface switching module can be composed of a system UI subsystem in the master control processing module and integrated in the graphical interface layer of the operating system. The module generates a floating control on the display device, which is used to carry the interface switching operation entrance. The floating control is presented in the form of icon, button or interactive graphics, and is always resident above the cloud computer desktop operation interface and can be triggered by touch, mouse click or gesture operation.

[0089] After the user triggers the floating control, the master control processing module sends an interface jump instruction to the operating system through the interface switching module, and switches the current display interface from the cloud computer remote desktop window to the locally deployed router management interface. The router management interface can be realized by a Web management page or a local embedded management application, and runs in the Web server or application server of the routing processing module.

[0090] The router management interface comprises a plurality of function display areas, such as:

[0091] The network status display area is used to show the current network status, connection mode, public network IP and the like.

[0092] Terminal access list, for displaying the terminal device MAC address, IP address, connection mode (WiFi / wired) and the like connected to the present device at present;

[0094] Security policy configuration entry, which can be used for access control list (ACL) configuration, port filtering, wireless encryption mode setting and the like.

[0095] The interface switching module realizes data request and interaction between the master processing module and the routing processing module through a local loopback address or a preset management port, and adopts, for example, HTTP, HTTPS or local Socket protocol for communication, so as to ensure real-time linkage of interface operation and routing function configuration.

[0096] Through the above structural design, the user can quickly enter the local routing management interface for network configuration under the premise of not exiting the cloud computer operation environment, and the use convenience and system integration degree are improved.

[0097] Further, the device further comprises an expansion subunit connected with the master processing module, and the expansion subunit comprises:

[0098] The display output interface is used for outputting video data through a differential signal;

[0099] The USB expansion module is used for connecting multiple external USB devices in a hub mode;

[0100] The display output interface is embedded with a display identification information storage unit.

[0101] In an embodiment of the present application, the device further comprises an expansion subunit electrically connected with the master processing module, which is used for expanding multiple input / output interfaces to meet the user peripheral access and audio / video output requirements.

[0102] The expansion subunit comprises:

[0103] 1. The display output interface module is used for outputting video signals in the master processing module to external display devices. The module adopts a physical interface based on a differential signal transmission standard, for example, an HDMI interface, and supports transmission of video data through a TMDS (Transition Minimized Differential Signaling) mode. A graphics output end in the master processing module is connected to the display output interface module through a display interface control channel, so as to realize output of high-definition video signals.

[0104] The display output interface module is embedded with a display identification information storage unit, such as an EDID (Extended Display Identification Data) chip in an EEPROM structure, for providing the host processing module with configuration information of the external display, such as device parameters, resolution support range, color depth, etc., so as to realize display adaptation.

[0105] 2. The USB extension module is used for extending the USB host controller of the host processing module into multiple external USB interfaces in a hub mode.

[0106] The USB extension module is connected to the USB controller interface of the host processing module through a standard USB bus, and further includes basic circuit units such as a pull-up resistor and an overcurrent protection circuit, so as to ensure the stability and safety of the USB device connection.

[0107] The interface modules of the above-mentioned extension sub-units are arranged in a concentrated manner on the I / O panel or the port expansion area of the device, and are uniformly scheduled and managed by the host processing module, so as to form a complete peripheral device access control path.

[0108] Further, the device further includes a state indication module, and the state indication module includes:

[0109] a network state indication circuit connected with the GPIO pin of the routing processing module;

[0110] a system running indication circuit connected with the host processing module;

[0111] a fault alarm circuit used for detecting the output voltage state of the power management module; and the circuits are electrically isolated through an isolating device.

[0112] In an embodiment of the present application, the device further includes a state indication module used for electrically monitoring and visually indicating and feeding back the system running state, the network connection state and the power abnormal state.

[0113] The network state indication circuit is connected with a GPIO (general input output) pin of the routing processing module. The GPIO pin is configured in an output mode and is used for outputting high and low level signals in different network states. The circuit is connected with a group of LED indicator lights, which are used for intuitively reflecting the WiFi connection state, WAN port connection state and network traffic activity on the device panel. The LED control circuit is configured with a current limiting resistor and a reverse protection diode, so as to ensure stable driving of the indicator lights.

[0114] The system operation indication circuit is connected with a controller or a specific state pin of the main control processing module. The controller can be a GPIO port integrated with a processor or a state output pin of a PMIC (power management chip). When the main control processing module is normally started and initialization is completed, the pin outputs a stable periodic pulse signal, which is used for driving the LED light to perform "breathing light" or flickering display, so as to prompt that the system is in an operation state.

[0115] The fault alarm circuit is connected to an output voltage monitoring port of the power management module and is used for real-time detection of the stability of power supply. The circuit is integrated with a voltage comparator unit, the input end of which is connected with the power output node. The comparator compares the detected voltage with a preset reference voltage. When the voltage is lower than a safe working threshold, the comparator outputs an alarm signal to an LED driving end or a buzzer control end, so as to realize warning and prompting of an abnormal power state.

[0116] In order to guarantee signal isolation and electrical safety between the indication circuits and the processor module, the functional units in the state indication module are all connected through optical coupling isolation devices for signal isolation. The optical coupling device adopts a unidirectional logic level conversion mode, which effectively avoids interference coupling between different voltage domains and improves system reliability.

[0117] Through the above structural design, the state indication module can perform multi-dimensional monitoring and feedback on the key states of device operation, so as to facilitate users and system administrators to quickly identify the current system state and perform maintenance operations.

[0118] Further, the main control processing module further includes a Bluetooth communication unit, which adopts an independent antenna structure and supports communication with external input devices through a Bluetooth 5.0 protocol.

[0119] In an embodiment of the present application, the main control processing module of the device further includes a Bluetooth communication unit, which is used for realizing data communication with external Bluetooth devices.

[0120] The Bluetooth communication unit can adopt a stand-alone Bluetooth chip integrated module, such as a SoC (System on Chip) Bluetooth module conforming to the Bluetooth 5.0 protocol. The module has a complete radio frequency transceiver circuit, a baseband processor, and a protocol stack, and is connected with the main control processing module through a serial port (UART) or a USB interface.

[0121] The Bluetooth communication unit adopts a stand-alone antenna structure, which is connected with the radio frequency output port of the Bluetooth module through a radio frequency connector (such as IPEX) or a built-in antenna wiring mode, to avoid interference coupling with the WiFi antenna. The antenna structure supports a multi-polarization gain design for stable realization of short-distance wireless signal transmission and reception.

[0122] The software part of the Bluetooth communication unit runs in the operating system of the main control processing module, including Bluetooth driver, device pairing service, input and output control interface, and the like. By loading the Bluetooth HCI (Host Controller Interface) protocol layer, the initialization, broadcasting, pairing, connection, data transmission, and the like of the Bluetooth module can be realized.

[0123] The Bluetooth communication unit supports communication connection with external input devices (such as Bluetooth keyboard, mouse, handle, audio input device, and the like). In the system startup process, the Bluetooth module can automatically broadcast a pairing signal, and after the external device completes pairing and binding, data interaction can be performed with the main control processing module through the Bluetooth protocol (such as HID or SPP).

[0124] The Bluetooth communication unit and the main control processing module communicate through a standard interface protocol, and the Bluetooth state information can be fed back to the system interface for unified management. The power supply of the Bluetooth unit is provided by the stabilized voltage branch output by the power management module, to ensure the communication stability.

[0125] Further, the power management module includes a step-down circuit and an overload protection unit.

[0126] The step-down circuit is used to convert the input voltage into multiple stable output voltages.

[0127] The overload protection unit is used to monitor the current state of each output channel and cut off the corresponding channel when an abnormality occurs.

[0128] In an embodiment of the present application, the device further includes a power management module for providing stable working voltage for the main control processing module and the routing processing module, and having current abnormality detection and overload protection capabilities.

[0129] The power management module includes:

[0130] A voltage reduction circuit is configured to convert an input power voltage (e.g. DC 12V or 5V) into multiple stable output voltages suitable for each sub-module. The voltage reduction circuit can be constructed using a DC-DC voltage reduction chip, which has multiple output channels, for example, providing 3.3V and 1.8V power supply for the main control processing module, 5V or 3.3V power supply for the routing processing module, etc.

[0131] Each output branch is configured with an output filter, including an inductor, a capacitor array and an ESD protection device, to suppress power supply noise and improve power supply stability.

[0132] An overload protection unit is configured to monitor the current state of each output branch in real time. When the output current of a branch exceeds a preset threshold, the protection unit immediately cuts off the power supply of the branch by controlling a switching circuit (e.g. a MOS tube), preventing load short circuit or device damage.

[0133] The overload protection unit includes a current sampling module, a voltage comparator and a control switch. The current sampling module detects the output current through a sampling resistor, and the comparator compares the actual current signal with a reference value to control the power-off logic.

[0134] In addition, the power management module can further include a voltage detection feedback circuit configured to provide power supply state information to the main control processing module for the system to determine whether the system is in a normal power supply state.

[0135] The power management module is integrated into a mainboard or a power supply board, and its input end is connected to an external adapter input power supply or a built-in battery, and its output end is connected to the main control processing module, the routing processing module, the Bluetooth communication unit, the USB expansion module and other system units through a power distribution network, forming a complete power supply path.

[0136] Further, the main control processing module periodically sends a detection signal to the routing processing module;

[0137] The routing processing module performs network parameter configuration operation, frequency band switching operation and connection state management according to the detection signal.

[0138] When a network anomaly is detected, the routing processing module feeds back state alarm information to the main control processing module.

[0139] In an embodiment of the present application, a master-slave communication detection mechanism is provided between the main control processing module and the routing processing module, which is used to realize state synchronization and instruction interaction between internal modules of the device.

[0140] The master processing module is configured with a timing scheduler for periodically generating a detection signal, which is sent to the routing processing module through a communication channel (such as a gigabit Ethernet physical link) set in the network interaction module. The detection signal is a data packet in a predefined format, containing a timestamp, device identification and command identification field, and conforms to the structure of a customized communication protocol.

[0141] After receiving the detection signal, the routing processing module analyzes its content and enters a response process, and performs operations including but not limited to:

[0142] Network parameter configuration, such as starting and stopping of DHCP service, setting of IP address allocation strategy;

[0143] Frequency band switching control, such as adjusting the WiFi access frequency band between 2.4GHz and 5GHz;

[0144] Access terminal management, such as limiting the connection authority of a MAC address or adjusting the bandwidth resource allocation.

[0145] The detection mechanism has a response feedback function. If the routing processing module normally analyzes and completes the related operation, it will generate a response frame and return it to the master processing module for state synchronization confirmation by the master module.

[0146] If no valid response is received within a set time window, the master processing module will enter an abnormal processing process and generate state alarm information according to the built-in alarm logic, display the abnormal state through the state indication module, or present prompt information through the display interface.
