Description

Technical Field

[0001] This application relates to the fields of computer communication and power management technology, and in particular to a centralized management and control platform for Type-C terminals. Background Technology

[0002] In centralized management scenarios for Type-C terminal devices (such as educational tablets, industrial robots, and VR glasses), there is a concurrent demand for high-power fast charging and high-speed, stable network data transmission. To address this concurrent demand, existing technologies attempt to integrate power supply and network functions using USB-A-based switch products (such as the WimoWM-ZB-U24 and TP-LINK TL-U8) as a centralized management platform for Type-C terminals. However, limited by the outdated physical and protocol specifications of the USB-A underlying architecture, these technologies suffer from at least the following drawbacks in implementing the aforementioned functions:

[0003] Firstly, poor cable compatibility: The interface type of the above-mentioned switch products is USB-A 2.0, which forces the use of customized USB-A to Type-C cables, making it impossible for standard Type-C cables to be directly adapted, thus violating the USB-IF interface direct connection specification;

[0004] Secondly, the concurrent performance is limited: multiple ports of the above-mentioned switch products share a single USB bus bandwidth and a protocol conversion chip; in scenarios with high concurrency access of multiple terminals (i.e., a large number of Type-C terminal devices are connected to the above-mentioned switch products at the same time and carry out high-load business operations simultaneously), serious resource contention problems will occur on each port, resulting in internal data transmission blockage and a significant decrease in speed.

[0005] Third, the power supply capacity is weak: the overall power supply of the above-mentioned switch products is low (usually no more than 240W), and multiple ports share power resources. The output power of a single port is low (usually no more than 15W), which cannot support fast charging protocols and can only achieve basic slow charging, seriously affecting the battery life and working efficiency of Type-C terminal devices.

[0006] Fourth, insufficient port density: Due to the bus load limitation of the USB Hub architecture, the maximum number of ports of the above-mentioned switch products is relatively small (usually no more than 8), which cannot adapt to high-concurrency access scenarios of multiple terminals. Summary of the Invention

[0007] In view of the above problems, this application provides a centralized management and control platform for Type-C terminals to eliminate the reliance on customized adapter cables, while solving the pain points of insufficient concurrency performance, weak power supply capacity, and insufficient port density, thereby achieving high-speed network transmission and true concurrency of high-power fast charging in scenarios with multiple terminals and high concurrency access. The specific solution is as follows:

[0008] This application provides a centralized management and control platform for Type-C terminals, including: a chassis, a main switching unit, two first power conversion modules, and a Type-C interface board array composed of multiple Type-C interface boards;

[0009] Both of the first power conversion modules are located inside the chassis and are used to convert external AC power into high-voltage DC power. They form a dual-path independent power supply architecture and jointly power the main switching unit and the Type-C interface board array.

[0010] The main switching unit is located inside the chassis and provides an Ethernet uplink interface;

[0011] The multiple Type-C interface boards are arranged in an array on the front panel of the chassis; each Type-C interface board includes a standard Type-C interface, a USB to Ethernet protocol conversion module, a fast charging protocol control module, a fast charging protocol output module, and a second power conversion module;

[0012] The USB to Ethernet protocol conversion module is used to perform bidirectional conversion between USB data signals and Ethernet data signals when a Type-C terminal device is connected to the standard Type-C interface, and communicates with the main switching unit through the internal bus to establish a wired network connection for the connected Type-C terminal device.

[0013] The fast charging protocol control module is used to perform a fast charging protocol handshake with the externally connected Type-C terminal device through the configuration channel of the standard Type-C interface, so as to identify the fast charging power requirements of the Type-C terminal device;

[0014] The input terminal of the fast charging protocol output module is used to receive the high voltage DC power, and the output terminal of the fast charging protocol output module is connected to the voltage bus pin of the standard Type-C interface; the fast charging protocol output module is controlled by the fast charging protocol control module and is used to dynamically adjust the power supply voltage and power of the voltage bus pin according to the fast charging protocol handshake result.

[0015] The second power conversion module is used to convert the high-voltage DC power into low-voltage DC power to power the low-voltage power module in the Type-C interface board;

[0016] The main switching unit is connected to the USB to Ethernet protocol conversion module in each of the Type-C interface boards via an internal bus to form a star network topology.

[0017] In one possible implementation, the Ethernet uplink interface is an RJ45 Gigabit adaptive Ethernet uplink interface, and the number of RJ45 Gigabit adaptive Ethernet uplink interfaces is two.

[0018] In one possible implementation, the fast charging protocol control module supports adaptive recognition of multiple mainstream fast charging protocols, including power transfer protocols and Qualcomm fast charging protocols.

[0019] In one possible implementation, the high-voltage DC power is 12V DC power; the maximum output power supported by the fast charging protocol output module is 24W.

[0020] In one possible implementation, the maximum output power of the Type-C terminal centralized management platform is not less than 600W, and the number of Type-C interface boards is 20.

[0021] In one possible implementation, each Type-C interface board also includes: a first status indicator and a second status indicator;

[0022] The USB to Ethernet protocol conversion module is also used to control the first status indicator light to illuminate when the wired network connection of the Type-C terminal device is established;

[0023] The fast charging protocol control module is also used to control the second status indicator light to illuminate when the fast charging protocol handshake is completed with the Type-C terminal device and fast charging starts normally.

[0024] In one possible implementation, the network signal traces and charging power traces on each of the Type-C interface boards are physically isolated from each other on the printed circuit board layout.

[0025] In one possible implementation, in the Type-C interface board, the characteristic impedance of the USB differential signal line between the standard Type-C interface and the USB to Ethernet protocol conversion module is controlled within the range of 90Ω±10%.

[0026] In one possible implementation, a network transformer is provided on the communication path between the USB to Ethernet protocol conversion module in each Type-C interface board and the main switching unit.

[0027] In one possible implementation, a heat dissipation module is integrated inside the chassis.

[0028] By employing the aforementioned technical solutions, the Type-C terminal centralized management platform provided in this application uses the standard Type-C interface as the terminal access carrier, fully complies with the USB-IF direct connection specification, eliminates the reliance on customized adapter cables, and solves the cable compatibility problem at its root. Simultaneously, this platform adopts a distributed architecture design, configuring an independent USB-to-Ethernet protocol conversion module for each Type-C interface board. Combined with a star network topology, it achieves independent bandwidth allocation for each port and line-speed non-blocking switching, completely eliminating the insufficient concurrent performance problem in high-concurrency access scenarios for multiple terminals under the traditional USB Hub architecture. Furthermore, this platform enhances the overall power capacity by constructing a dual-path independent power supply architecture. On one hand, it provides sufficient power support for the stable operation of multiple ports simultaneously, thereby breaking through the bus load limitations of traditional architectures and achieving increased port density. On the other hand, it provides a stable power foundation for high-power fast charging. Combined with the collaborative work of the fast charging protocol control module and the fast charging protocol output module, it dynamically adjusts the power supply parameters according to the fast charging protocol handshake results to achieve high-power fast charging on a single port. Ultimately, it achieves true concurrent operation of high-speed network transmission and high-power fast charging in high-concurrency access scenarios for multiple terminals.

Detailed Implementation

[0034] Type-C (full name USB Type-C) is a USB (Universal Serial Bus) interface technology standard officially released by the USB standardization organization (USB-IF) in 2014. It specifically refers to a new generation of device connection interface that adopts a symmetrical elliptical interface shape and supports multi-protocol compatibility. Its core positioning is to solve the industry pain points of inconsistent form, single function and poor compatibility of traditional USB interfaces (such as USB-A and USB-B), and become the "universal connection hub" of electronic devices.

[0035] In scenarios involving centralized management of Type-C terminal devices, there is a concurrent demand for high-power fast charging and high-speed, stable network data transmission. Existing technologies attempt to meet this concurrent demand through USB-A-based switch products, but suffer from problems such as poor cable compatibility, limited concurrent performance, weak power supply capacity, and insufficient port density. To address this, this application provides a centralized management platform for Type-C terminals. Through a standard Type-C interface (also known as a native Type-C interface, specifically referring to an interface designed to fully comply with the Type-C standard specifications defined by the USB-IF organization), fast charging protocol compatibility, and a large-capacity redundant power supply architecture, it solves the aforementioned problems and achieves true concurrency of high-speed network transmission and high-power fast charging in scenarios with multiple terminals and high concurrency access.

[0036] The following detailed description, with reference to the accompanying drawings, describes a centralized management and control platform for Type-C terminals provided in the embodiments of this application. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0037] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms are interchangeable where appropriate; this is merely a way of distinguishing objects with the same attributes in the embodiments of this application. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, so that a process, method, system, product, or apparatus that comprises a series of elements is not necessarily limited to those elements, but may include other elements not explicitly listed or inherent to those processes, methods, products, or apparatuses.

[0038] like Figure 1 As shown in the figure, an embodiment of this application provides a centralized management and control platform for Type-C terminals, including: a chassis ( Figure 1 (Not shown in the image) Main switching unit 100, two first power conversion modules 200 and a Type-C interface board array 300 composed of multiple Type-C interface boards;

[0039] Both first power conversion modules 200 are located inside the chassis and are used to convert external AC power into high-voltage DC power (in one possible implementation, it supports a wide voltage AC input of 100~240V, corresponding to a maximum input current range of 12A at 100V and a maximum input current range of 9.5A at 240V). Figure 1 This article only uses the first power conversion module 200 to convert the common 220V AC power to 12V DC power as an example; in addition, the "high voltage" in this article is relative to the "low voltage" after the subsequent conversion, and the two first power conversion modules 200 form a dual independent power supply architecture, which together power the main switching unit 100 and the Type-C interface board array 300.

[0040] The main switching unit 100 is located inside the chassis and provides an Ethernet uplink interface;

[0041] The multiple Type-C interface boards are arranged in an array on the front panel of the chassis; for example Figure 2 As shown, each Type-C interface board includes a standard Type-C interface 301, a USB to Ethernet protocol conversion module 302, a fast charging protocol control module 303, a fast charging protocol output module 304, and a second power conversion module 305;

[0042] The USB to Ethernet protocol conversion module 302 is used to perform bidirectional conversion between USB data signals and Ethernet data signals when a Type-C terminal device is connected to the standard Type-C interface 301, and communicates with the main switching unit 100 through the internal bus, thereby establishing a wired network connection for the connected Type-C terminal device.

[0043] The fast charging protocol control module 303 is used to perform a fast charging protocol handshake with the externally connected Type-C terminal device through the CC (Configuration Channel) of the standard Type-C interface 301 to identify the fast charging power requirements of the Type-C terminal device;

[0044] The input terminal of the fast charging protocol output module 304 is used to receive the high-voltage DC power (e.g. Figure 1 The output terminal of the fast charging protocol output module 304 (shown as 12V DC power) is connected to the VBUS pin (i.e., voltage bus pin) of the standard Type-C interface 301; the fast charging protocol output module 304 is controlled by the fast charging protocol control module 303 and is used to dynamically adjust the voltage and power of the VBUS pin power supply signal according to the fast charging protocol handshake result.

[0045] The second power conversion module 305 is used to convert the high-voltage DC power into low-voltage DC power, providing power to low-voltage power modules within the Type-C interface board, such as the fast charging protocol control module 303 and the fast charging protocol output module 304. Figure 1 (The example only uses the second power conversion module 305 to convert 12V DC to 5V DC.)

[0046] The main switching unit 100 is connected to the USB to Ethernet protocol conversion module 302 in each of the Type-C interface boards via an internal bus to form a star network topology.

[0047] The Type-C terminal centralized management and control platform described in this application's embodiments is fundamentally based on an innovative distributed architecture that enables stable, reliable, and truly concurrent operation of wired network access and high-power fast charging for high-density Type-C terminal devices. Its working principle can be described in the following three stages:

[0048] Phase 1: Terminal Access and Network Connection Establishment

[0049] When a Type-C terminal device is connected to any standard Type-C interface 301 of this platform via a standard Type-C cable, a physical connection is established. Subsequently, a USB-to-Ethernet protocol conversion module 302 (e.g., based on an RTL8152B chip) located on the same Type-C interface board is activated. The activated USB-to-Ethernet protocol conversion module 302 establishes a USB communication link with the currently connected Type-C terminal device via the USB differential signal line in the standard Type-C interface 301, and follows the CDC (Communications Device Class) protocol to convert the USB data format into standard Ethernet data frames. The converted Ethernet data frames are then uploaded to the main switching unit 100 via the internal bus. The CDC protocol here has cross-platform compatibility, directly adapting to mainstream operating systems such as Windows, macOS, Android, and iOS. When a Type-C terminal device is connected, automatic recognition is achieved without the need for manual installation of a dedicated driver, fundamentally solving the pain points of poor cross-platform compatibility and high maintenance costs associated with traditional devices. The main switching unit 100 serves as the network core, allocating an independent network channel to each connected Type-C interface board, thereby forming a star network topology in terms of physical connection.

[0050] The key innovation of this architecture lies in the fact that each Type-C interface board integrates an independent, dedicated USB-to-Ethernet protocol conversion module 302 for its own port. This means that the protocol conversion function is completely distributed; data from each port is converted into Ethernet frames on the local Type-C interface board. Ethernet data from all ports is switched at line speed and without blocking on the standard switching chip in the main switching unit 100. Therefore, this platform fundamentally abandons the traditional USB-A switch model of "multiple ports sharing a single USB Hub bus and a protocol conversion chip," completely eliminating internal blocking and performance degradation caused by resource contention in high-concurrency scenarios, and achieving true multi-port full-speed concurrent data transmission.

[0051] Phase Two: Fast Charging Protocol Negotiation and Power Supply Activation

[0052] At the same moment that a Type-C terminal device is connected, the fast charging protocol control module 303 (e.g., using a protocol chip such as LDR6023Q) located on the corresponding Type-C interface board starts working through the CC channel. Its specific operation is as follows:

[0053] The fast charging protocol control module 303 first performs physical layer connection detection to confirm that the connected Type-C terminal device is a powered device; then, it initiates a fast charging protocol handshake with the powered device via the CC line. The fast charging protocol control module 303 supports adaptive recognition of multiple mainstream fast charging protocols, including PD (Power Delivery) and QC (Quick Charge). During the handshake process, the fast charging protocol control module 303 and the powered device communicate digitally via the CC line, first exchanging power supply capability information; then, based on the exchanged information, the fast charging protocol control module 303 accurately identifies the fast charging requirements of the powered device—including the types of fast charging protocols it supports and its acceptable voltage and current ranges; finally, both parties negotiate and determine a specific set of output voltage and current levels.

[0054] After negotiation, the fast charging protocol control module 303 sends a setting command containing the voltage and current values ​​to the fast charging protocol output module 304 (such as an integrated solution based on IP6537D). The input terminal of the fast charging protocol output module 304 is directly connected to the high-voltage DC bus provided by the dual-path independent power supply architecture composed of two first power conversion modules 200. This dual-path independent power supply architecture can significantly improve the overall power capacity (e.g., provide a total power reserve of up to 600W), providing sufficient power support for the stable operation of multiple ports simultaneously, thereby breaking through the bus load limitation of traditional architectures and realizing an increase in port density; moreover, this power redundancy design ensures that in the event of a power failure in one path, the other path can seamlessly take over the entire load, ensuring the reliability of continuous industrial-grade operation. With sufficient and stable power input, the fast charging protocol output module 304, according to the received setting command, dynamically adjusts the high-voltage DC bus voltage to the negotiated output voltage through efficient synchronous buck conversion. Then, via the VBUS and GND pins of the standard Type-C interface 301, while providing the negotiated stable voltage, the output current is limited to the negotiated maximum value, thus achieving high-power fast charging on a single port. For example, if the fast charging protocol output module 304 dynamically adjusts the 12V high-voltage DC bus to a negotiated fast charging level such as 9V or 12V, and the output current is limited to the negotiated maximum value of 2A, then a maximum output power of 24W can be achieved on a single port. When this dual-path independent power supply architecture can provide a total power reserve of up to 600W, this platform can ensure the power requirements of 20 ports operating at full load of 24W (20 × 24W < 600W), far exceeding the maximum number of 8 ports in existing USB-A based switch products.

[0055] Furthermore, since the two first power conversion modules 200 are integrated into the built-in power unit within the chassis, they directly convert external AC power into high-voltage DC power, allowing the platform to operate without a separate external power adapter. This eliminates the risk of system power outages caused by loose adapter interfaces, accidental cable disconnections, or individual failures of external devices, making the power connection more robust and reliable. Users only need a standard power cord to connect the device to a mains outlet, eliminating the need to carry, store, and match specific external adapters, greatly simplifying the deployment and maintenance process.

[0056] Phase 3: Stable concurrent operation of network and fast charging

[0057] After completing the physical access of the Type-C terminal device, network protocol negotiation, and fast charging protocol handshake, the system enters an independent operation phase in which network data flow and fast charging power flow are completely parallel, achieving a true concurrent effect of "synchronous and stable data transmission and power supply".

[0058] The network data flow path is as follows: Type-C terminal device ↔ Standard Type-C interface 301 ↔ USB to Ethernet protocol conversion module 302 ↔ Main switching unit 100 ↔ Ethernet uplink interface ↔ Uplink devices in the external network (such as routers, switches, gateways, etc.).

[0059] The fast charging power flow path is: first power conversion module 200 (12V bus) ↔ fast charging protocol output module 304 ↔ standard Type-C interface 301 (VBUS / GND pin) ↔ Type-C terminal device.

[0060] In summary, the Type-C terminal centralized management platform provided in this application uses the standard Type-C interface 301 as the terminal access carrier, fully complies with the USB-IF direct connection specification, eliminates the dependence on customized adapter cables, and solves the cable compatibility problem from the root. At the same time, this platform adopts a distributed architecture design, configuring an independent USB to Ethernet protocol conversion module 302 for each Type-C interface board, combined with a star network topology to achieve independent bandwidth allocation and line-speed non-blocking switching for each port, completely eliminating the problem of insufficient concurrent performance in high-concurrency access scenarios of multiple terminals under the traditional USB Hub architecture. This platform also improves the overall power capacity by constructing a dual-path independent power supply architecture. On the one hand, it provides sufficient power support for the stable operation of multiple ports at the same time, thereby breaking through the bus load limitation of the traditional architecture and realizing the increase in port density. On the other hand, it provides a stable power foundation for high-power fast charging. With the collaborative work of the fast charging protocol control module 303 and the fast charging protocol output module 304, the power supply parameters are dynamically adjusted according to the fast charging protocol handshake results to realize high-power fast charging on a single port. Ultimately, it realizes true concurrent operation of high-speed network transmission and high-power fast charging in high-concurrency access scenarios of multiple terminals.

[0061] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the Ethernet uplink interface provided by the main switching unit 100 adopts an RJ45 gigabit adaptive uplink interface.

[0062] Specifically, the RJ45 gigabit adaptive uplink interface supports adaptive speed and automatic negotiation of duplex mode. It also complies with three Ethernet standard protocols: IEEE 802.3 (defining a 10Mbps Ethernet standard for low-speed compatibility), IEEE 802.3u (defining a 100Mbps Fast Ethernet standard for medium-speed compatibility), and IEEE 802.3ab (defining a 1000Mbps gigabit Ethernet standard for high-speed transmission requirements of the platform core). With a speed limit of 1000Mbps, it is backward compatible with mainstream speeds such as 10Mbps and 100Mbps. It can dynamically match the port speed and duplex mode (full-duplex / half-duplex) of the uplink device, establishing a stable network connection without manual configuration. It is compatible with uplink devices of different ages and speed specifications, significantly improving the deployment flexibility and compatibility of centralized management scenarios.

[0063] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the number of RJ45 gigabit adaptive uplink interfaces is two, realizing a redundancy backup function: when one of the uplink links fails (such as cable damage or uplink device port failure), the other link can seamlessly switch over and take over data transmission, ensuring the continuity and stability of the connection between this platform and the external network, and further improving the network reliability in centralized management and control scenarios.

[0064] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, each Type-C interface board further includes: a first status indicator and a second status indicator; the USB to Ethernet protocol conversion module 302 is further used to control the first status indicator (e.g., a blue light) to illuminate when the wired network connection of the Type-C terminal device is established; the fast charging protocol control module 303 is further used to control the second status indicator (e.g., a red light) to illuminate when the fast charging protocol handshake with the Type-C terminal device is completed and fast charging is started normally. Thus, this platform intuitively reflects the network connection status and fast charging working status of the corresponding standard Type-C interface through the illumination status of different colored indicator lights, facilitating maintenance personnel to quickly troubleshoot device access faults and understand the platform's operating status.

[0065] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the network signal traces and charging power traces on each Type-C interface board are physically isolated on the PCB layout (such as using a split PCB layout) to ensure that the electromagnetic noise generated during high-power charging does not affect the fragile high-speed data signal, thereby eliminating the common problem of data transmission interruption or instability caused by power supply interference in traditional solutions.

[0066] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the characteristic impedance of the USB differential signal line between the standard Type-C interface and the USB to Ethernet protocol conversion module in the Type-C interface board is controlled within the range of 90Ω±10%, thereby ensuring the integrity of USB data signal transmission. Here, characteristic impedance is the resistance of a signal line to AC signals during signal transmission. Controlling it within this standard range ensures the integrity of USB data signal transmission, reduces signal reflection, attenuation, and crosstalk, and guarantees the stability of high-speed data transmission.

[0067] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, to ensure the link stability and signal integrity of Ethernet data transmission in scenarios with high concurrency access from multiple terminals, a network transformer (e.g., model HST-2027DG) is provided on the communication path between the USB to Ethernet protocol conversion module 302 in each Type-C interface board and the main switching unit 100. The core function of this network transformer is to cut off the potential interference conduction path between the USB to Ethernet protocol conversion module 302 and the main switching unit 100 through an electrical isolation mechanism, while specifically suppressing high-frequency common-mode noise generated by the centralized operation of multiple devices, and possessing surge interference resistance capability, providing comprehensive protection for data transmission at the link level.

[0068] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the chassis of this platform is provided with fixing components (commonly known in the industry as "hanging ears") extending from both sides. The core function of these fixing components is to provide rack-mountable adaptation capability for this platform. The chassis can be securely mounted to an external bracket or rack using fasteners (such as Phillips head screws and expansion bolts), precisely meeting the standardized deployment requirements in centralized management and control scenarios. The fixing components are preferably made of metal materials (such as cold-rolled steel plates and aluminum alloys) in one piece. In some lightweight scenarios, high-strength engineering plastic materials can be selected. Both materials can ensure the structural stability after installation. At the same time, the symmetrical layout design makes the chassis bear the force evenly, effectively reducing the impact of vibration on the internal core components. This design can significantly improve the space utilization of the computer room or control center and facilitate subsequent operation and maintenance.

[0069] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the chassis of this platform integrates a high-efficiency heat dissipation module (such as an aluminum extruded heat sink and an intelligent temperature-controlled fan array). The aluminum extruded heat sink adopts a surface-contact bonding design, tightly laid on the surface of core heat source components such as the first power conversion module 200 and the fast charging protocol output module 304, achieving rapid conduction and diffusion of heat. Simultaneously, the system is equipped with a real-time temperature monitoring unit and a closed-loop temperature control mechanism. Temperature sensors dynamically collect temperature data from inside the chassis and core components, precisely controlling the fan array speed to dynamically match the heat dissipation capacity with the actual heat load requirements. This ensures that even under extreme conditions of full-port full-load operation, the operating temperature of each key component can be stably controlled below the 85℃ threshold, providing reliable assurance for the stability of long-term continuous operation of the platform from a thermal management perspective and effectively extending the service life of core components.

[0070] In one possible implementation, based on any of the Type-C terminal centralized management and control platforms provided in the embodiments of this application, the platform has the adaptability of "fast charging compatibility + basic charging backup" - when the connected Type-C terminal device does not support the fast charging protocol (such as old devices or simple devices that only require basic power supply), without protocol negotiation, the platform will automatically switch to the default charging mode and output basic power (such as basic power of 5V voltage and 2A current) to achieve basic slow charging, ensuring that the device can be charged normally and avoiding the problem of power supply failure due to protocol incompatibility.

[0071] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the embodiments of this application. Therefore, the embodiments of this application are not to be limited to the embodiments shown herein, but are to be accorded the widest scope consistent with the principles and novel features disclosed herein.
