[0002] In the current digital office and entertainment scenarios, the types and number of electronic devices are constantly increasing, and users' needs for inter-device connections and data transmission are becoming more diverse and complex. As laptops, tablets, mobile phones and other devices become thinner and lighter, the number of their own interfaces decreases, making it difficult to meet the needs of connecting multiple external devices at the same time. For example, when working, users often need to connect monitors, keyboards, mice, mobile hard drives and other devices at the same time; in entertainment scenarios, they also need to connect projectors, game controllers, etc. The traditional docking station has relatively simple functions, with only basic charging and simple data transmission functions, and cannot meet the requirements of high-speed, multi-protocol data transmission.

[0003] After extensive searching, the publication number CN118916317A was found, which disclosed a method for implementing a multifunctional TYPEC interface of a docking station. By using multiple PD chips, each TYPEC interface can be independently powered, transmit data, or connect to an external display, which greatly enhances the functional diversity of the docking station.

[0004] However, there are still problems such as limited integration of docking station interface functions, insufficient intelligence in data transmission management, imperfect device connection detection and adaptation functions, and lack of heat dissipation design. In terms of interface functions, it mainly revolves around the TYPEC interface, and the diversity of interface types is insufficient, making it difficult to meet the needs of a wide range of device connections; data transmission management only focuses on basic functions, lacks the intelligent ability to dynamically allocate bandwidth according to data types and device requirements, monitor signal quality in real time, and adjust processing parameters; device connection detection and adaptation functions are not comprehensive enough, and heat dissipation cannot be controlled according to the number of connected devices and power size; the lack of heat dissipation design means that when multiple devices are connected and high-speed data transmission is carried out, the heating problem of the device cannot be effectively solved. As a result, when users use the docking station, they face limited device connection, low data transmission efficiency, poor device compatibility, and performance and stability of the device affected by overheating.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1 In order to achieve the effect of multi-protocol device access and preliminary adaptation, an embodiment provided by the present invention can be combined with Figure 1 , Figure 3 and Figure 4 To understand. Figure 1In the main structure of the dock, we can clearly see the overall layout of the dock. The layout is compact and reasonable, fully considering ergonomics and space efficiency, and building a stable and convenient physical foundation for the access of multi-protocol devices. When the power supply of the dock is connected to an external power supply through the Type-C output connector, and then compared Figure 3 By looking at the core component structure diagram of , it can be known that the power management module 26 has been started.

[0033] The traditional power conversion method has certain limitations in efficiency and stability, while the AC-DC conversion unit of the present invention adopts advanced high-frequency switching power supply technology, and its conversion efficiency can be as high as 95% or more, which is about 10%-15% higher than the traditional conversion method. This not only reduces energy loss and heat generation, but also provides more stable direct current for the device. The intelligent power distribution unit has a built-in dynamic power distribution model based on a machine learning algorithm, which can analyze the power demand pattern of the connected device in real time and quickly and accurately distribute power at the moment the device is connected. For example, when a high-power mobile hard disk is connected, the power supply can be adjusted to the appropriate level within 0.1 seconds, which greatly improves the flexibility and efficiency of power supply compared to the traditional fixed power distribution method. The high-precision voltage regulation unit uses a voltage regulation chip with nanovolt accuracy, which can control the fluctuation of the output voltage within ±0.01V, ensuring that the device can obtain a stable voltage supply under different working conditions.

[0034] According to the type of external device, the user Figure 4 The input interface connection process is as follows: connect the ordinary USB device to the first USB-A connector 231 or the second USB-A connector 232; the display supporting the DisplayPort protocol is connected through the DisplayPort interface 233; if the HDMI connection is used, the adapter cable is used to Figure 2 The HDMI reserved slot 113 shown in the shell structure 11 is connected; the device supporting the Type-C protocol is connected to the Type-C input connector 234; the device supporting the Thunderbolt protocol is connected to the Thunderbolt input connector 235. These interfaces all use advanced electrical isolation and signal shielding technology, which can effectively reduce signal interference and crosstalk, and ensure the independent and stable transmission of signals of different protocols. The device connection detection and adaptation submodule of the intelligent management module 25 monitors the device connection status of the input interface module 23 based on the CC communication protocol. It uses a high-speed signal detection circuit and an intelligent recognition algorithm, which can accurately identify the device type within 0.05 seconds. After identifying the device type, the power supply voltage of the power management module 26 and the signal transmission mode of the signal processing module 24 are automatically adjusted. At the same time, the initial speed of the cooling fan 14 is controlled according to the number and power of the connected devices to ensure that the device can enter the best working state at the moment of connection.

[0035] Embodiment 2 In order to achieve efficient signal processing and optimized transmission, such as Figure 3 , Figure 6 and Figure 8 As shown, an embodiment provided by the present invention: Figure 3 It can be seen that the core component 2 is composed of a signal from an external device entering the docking station through the input interface module 23, and signals of different protocols are transmitted through their own independent channels. Figure 6 The signal processing flow is as follows, and the signal processing module 24 starts working.

[0036] The multi-protocol data processing unit uses a dedicated chip with a multi-core architecture. It has 8 high-performance processing cores, each of which can operate at a speed of more than 3GHz. It can process signals of multiple different protocols in parallel at the same time, and its processing capacity is 6-8 times higher than that of traditional single-core chips. The chip also integrates advanced protocol parsing and conversion algorithms, which can complete the conversion between different protocol signals within 0.01 seconds, ensuring efficient data transmission. The high-speed signal amplification and equalization unit amplifies and compensates the high-frequency differential signal, and adopts an amplifier with low noise and high gain characteristics and an adaptive equalization algorithm. When transmitting high-speed data, the signal attenuation can be controlled within 1dB, while effectively suppressing the jitter and distortion of the signal, reducing the signal bit error rate to less than 10⁻¹², greatly improving the signal transmission quality. The high-speed MUX switching unit introduces a high-speed analog switch and an intelligent switching algorithm, which can quickly and accurately switch the signal transmission path according to the device connection status and data transmission requirements within 0.001 seconds, realizing seamless signal switching and avoiding data transmission interruption.

[0037] The data transmission management submodule of the intelligent management module 25 adopts an intelligent data scheduling algorithm. Figure 8 The intelligent management module of the data transmission management process dynamically allocates bandwidth according to the data type and device requirements. The algorithm is based on real-time data traffic monitoring and prediction models, and can flexibly allocate bandwidth resources according to the priority and real-time requirements of different data types such as video, audio, and file transfer. For example, when playing high-definition video, the bandwidth can be allocated to the video stream first to ensure smooth playback of the video. At the same time, the signal quality is monitored in real time and the processing parameters of the signal processing module 24 are adjusted. When the amount of data transmission increases and the heat of the device increases, the data transmission management submodule cooperates with the system monitoring and logging submodule to allow the cooling fan 14 control unit to increase the fan speed. Through precise temperature sensors and intelligent control algorithms, the operating temperature of the equipment can be controlled between 40℃-50℃, ensuring the stability and reliability of the equipment when running under high load.

[0038] Embodiment 3 In order to achieve the effect of display device adaptation and stable display, such as Figure 1 , Figure 3 and Figure 8 As shown, an embodiment provided by the present invention: Referring to Figure 1 The main structure and Figure 3 The core component structure of the display output management submodule is as follows: If a display is connected, the display output management submodule reads the EDID information of the display through the AUX channel. The EDID information contains detailed parameters of the display, such as resolution, refresh rate, color mode, etc. The display output management submodule adopts high-precision information reading circuit and intelligent analysis algorithm, which can accurately read and analyze EDID information within 0.02 seconds.

[0039] The video signal format and display settings, such as resolution and refresh rate, output by the signal processing module 24 are automatically adjusted based on the information. When adjusting the resolution, it is possible to quickly switch between a variety of common resolutions such as 1080p, 2K, 4K, etc., with a switching time of less than 0.1 seconds. At the same time, the adjustment of the refresh rate can also accurately match the support range of the display to ensure smooth display of the picture. In terms of color mode adjustment, the color parameters of the video signal can be automatically optimized according to the color gamut and color characteristics of the display, so that the color reproduction of the display screen is increased to more than 98%, greatly improving the visual experience.

[0040] Combined with Figure 8 The process monitors the display connection status in real time, and automatically adjusts the signal transmission path and display settings when the display is connected or disconnected. It adopts a high-speed signal detection circuit and intelligent switching algorithm, which can detect the connection or disconnection status of the display within 0.03 seconds, and quickly adjust the signal transmission path to ensure seamless switching of the display. If the connection of a high-resolution, high-refresh rate display causes the load of the signal processing module 24 to increase and the heat to increase, the display output management submodule cooperates with the system monitoring and logging submodule to increase the speed of the cooling fan 14. Through precise temperature sensors and intelligent control algorithms, the speed of the cooling fan 14 can be dynamically adjusted according to the real-time temperature of the equipment, ensuring that the temperature of the equipment is always kept within a safe range when running at high load, avoiding performance degradation and display abnormalities due to overheating.

[0041] Embodiment 4 In order to achieve the effects of equipment status monitoring, data output and disconnection management, such as Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown, an embodiment provided by the present invention: Figure 3The layout of the core component 2 can be understood. The system monitoring and log recording submodule monitors the operating status of the core component 2 in real time. Through various sensors such as temperature sensors, voltage sensors, and current sensors near key modules on the circuit board 21, the temperature, voltage, current and other parameters of the device can be obtained in real time. These sensors have the characteristics of high precision and high response speed. The measurement accuracy of the temperature sensor can reach ±0.1℃, the measurement accuracy of the voltage sensor can reach ±0.001V, and the measurement accuracy of the current sensor can reach ±0.001A.

[0042] When the temperature exceeds the preset threshold, such as 50°C, Figure 5 The power management process immediately controls the cooling fan 14 to increase the speed. The cooling fan 14 adopts an efficient DC brushless motor and an optimized air duct design. The speed adjustment range is 1000-5000 rpm, and the cooling capacity can be quickly adjusted according to the actual temperature requirements of the equipment. This submodule records in detail the time and device type of the device connected and disconnected through each reserved slot, as well as abnormal data transmission events and the speed adjustment of the cooling fan 14. It adopts a large-capacity storage chip and an efficient data recording algorithm, which can record more than 10,000 event records, providing detailed data support for equipment troubleshooting and performance optimization.

[0043] After processing and management, the processed data is transmitted to the target device through the network interface module 22 or other corresponding output interfaces, such as video signals through the DisplayPort interface 233 or Figure 2 The data is transmitted to the display through the adapter cable connected to the HDMI reserved slot 113, and the data is transmitted to the external storage device through the USB interface. The network interface module 22 adopts a high-speed network chip and an optimized signal transmission circuit, and the data transmission rate can reach more than 10Gbps, ensuring fast and stable data transmission.

The AC-DC conversion unit quickly converts the alternating current into direct current, the intelligent power distribution unit is also ready for dynamic power distribution, and the high-precision voltage regulation unit is on standby at any time to accurately adjust the output voltage. Subsequently, the user can select an adapter interface for connection according to the type of external device to be connected. Ordinary USB devices can be connected to the first USB-A connector 231 or the second USB-A connector 232; if a device that supports the DisplayPort protocol, such as a monitor, is connected, the DisplayPort interface 233 can be used, and if an HDMI connection is required, it is connected through the HDMI reserved slot 113 through an adapter cable; devices that support the Type-C protocol are connected to the Type-C input connector 234; devices that support the Thunderbolt protocol are connected to the Thunderbolt input connector 235.

[0045] After the device is connected, the device connection detection and adaptation submodule of the intelligent management module 25 starts to monitor the device connection status of the input interface module 23 in real time based on the CC communication protocol. Once the type of the newly connected device is identified, the power supply voltage of the power management module 26 will be automatically adjusted to ensure that the device obtains appropriate power, and the signal transmission mode of the signal processing module 24 will be adjusted to adapt to the device protocol and data transmission requirements. In addition, this submodule will also control the initial speed of the cooling fan 14 according to the number and power of the connected devices to create a suitable cooling environment for the operation of the device.

[0046] After the signal of the external device enters the docking station through the input interface module 23, the signals of different protocols are transmitted through their own independent channels. At this time, the signal processing module 24 starts to process the input signal. The multi-protocol data processing unit uses a dedicated chip with a multi-core architecture to process different types of signals at the same time and convert them into a suitable format. The high-speed signal amplification and equalization unit amplifies and compensates the high-frequency differential signal to improve the signal transmission quality and reduce attenuation and distortion. The high-speed MUX switching unit quickly and accurately switches the signal transmission path according to the device connection status and data transmission requirements.

[0047] The data transmission management submodule of the intelligent management module 25 then comes into play. It uses an intelligent data scheduling algorithm to dynamically allocate bandwidth according to data type and device requirements to ensure that data transmission of each device can be supported by reasonable resources. At the same time, this submodule monitors the signal quality in real time, and once it finds that the signal quality has deteriorated, it will immediately adjust the processing parameters of the signal processing module 24. When the amount of data transmission increases and the device heats up, the data transmission management submodule will cooperate with the system monitoring and log recording submodule to feedback the heat situation to the cooling fan 14 control unit, prompting it to appropriately increase the fan speed.

[0048] If a display is connected, the display output management submodule will read the EDID information of the display through the AUX channel. Based on the information read, it automatically adjusts the video signal format and display settings output by the signal processing module 24, such as resolution, refresh rate, etc. In addition, the submodule will monitor the connection status of the display in real time, and automatically adjust the signal transmission path and display settings when the display is connected or disconnected. If the connection of a high-resolution, high-refresh rate display causes the signal processing module 24 to increase the load and heat generation, the display output management submodule will cooperate with the system monitoring and logging submodule to increase the speed of the cooling fan 14 to maintain stable operation of the equipment.

[0049] The system monitoring and logging submodule always monitors the operating status of the core component 2 in real time, monitors the temperature, voltage, current and other parameters of each module, and the temperature sensors near the key modules on the circuit board 21 also feedback the temperature information in real time. Once the temperature exceeds the preset threshold, the submodule will immediately control the cooling fan 14 to increase the speed to reduce the device temperature. At the same time, it will record in detail the time and device type of the device connected and disconnected through each reserved slot, as well as the abnormal events during the data transmission process and the speed adjustment of the cooling fan 14, forming a detailed log file.

[0050] After a series of processing and management, the processed data is transmitted to the target device through the network interface module 22 or other corresponding output interfaces. The video signal is transmitted to the display through the adapter cable connected to the DisplayPort interface 233 or the HDMI reserved slot 113 to realize image display, and the data is transmitted to the external storage device through the USB interface.

[0051] When the user disconnects the external device, the device connection detection and adaptation submodule will detect this and then adjust the power distribution of the power management module 26 and the working mode of the signal processing module 24. The system monitoring and log recording submodule will record the device disconnection time and device type, and the cooling fan 14 will also adjust the speed to an appropriate level according to the device load.
