Description

Technical Field

[0001] This disclosure generally relates to a low-power docking station with wireless charging capability and a method for monitoring its power consumption. Background Technology

[0002] A docking station, also known as a port replicator, is an external device used in computer systems and portable computer systems. By replicating or even expanding the ports of a laptop, it allows for convenient one-stop connection between the laptop and multiple accessories or external devices (such as power adapters, network cables, mice, external keyboards, printers, and external monitors).

[0003] Most existing docking stations, especially USB / WUSB docking stations, are designed for plug-and-play operation. Once connected to a computer via USB cable, data cable, or wireless connection, all drivers in the docking station begin working, and the internal modules associated with each external interface are powered on and begin functioning. Typically, a docking station provides multiple external device interfaces. If some of these interfaces are not connected to their corresponding external devices, such as printers or monitors, the docking station's internal graphics or video modules will not automatically stop processing graphics, video, or other data from the computer, resulting in wasted power consumption.

[0004] Moreover, some interfaces of existing low-power docking stations have the function of transmitting data and current at the same time. However, data and current transmission often occur simultaneously. Therefore, when only charging or data transmission is required, the simultaneous operation of data and current processing modules will cause unnecessary power consumption waste. Summary of the Invention

[0005] This disclosure is made in view of the above-mentioned state of the prior art, and its purpose is to provide a low-power docking station with wireless charging function that can reduce the internal power consumption of the docking station and a power consumption monitoring method thereof.

[0006] To this end, the first aspect of this disclosure provides a low-power docking station with wireless charging functionality, comprising a bus interface and multiple peripheral interfaces. The low-power docking station connects to a terminal via the bus interface and acquires input current and input data from the terminal. It connects to peripheral devices via the peripheral interfaces and transmits output current and output data to the peripheral devices. The docking station includes:

[0007] A wireless charging module includes a wireless electromagnetic induction charging base, a high-frequency transmitting module disposed on one side of the wireless electromagnetic induction charging base, a frequency converter connected to the high-frequency transmitting module, and an AC / DC converter connected to the frequency converter.

[0008] The processing module has a first end connected to the bus interface and a second end connected to multiple peripheral interfaces. The processing module is used to decode, transcode, and distribute the input data to the multiple peripheral interfaces.

[0009] The monitoring module includes a data detection module and a current monitoring module. The monitoring module is connected to multiple peripheral interfaces to monitor whether any peripheral devices are connected to the multiple peripheral interfaces and to generate corresponding monitoring signals.

[0010] The data detection module has its first end connected to multiple peripheral interfaces. The data detection module is used to detect whether the output data lines in the peripheral interfaces are working and to generate a first detection signal.

[0011] A data transmission control module, the first end of which is connected to the third end of the processing module, and the second end of which is connected to the second end of the data detection module, the data transmission control module being used to control the transmission of the output data in the processing module according to the first detection signal;

[0012] The current detection module has its first end connected to multiple peripheral interfaces. The current detection module is used to detect whether the output current line in the multiple peripheral interfaces is working and to generate a second detection signal.

[0013] A power supply module, with its first terminal connected to the fourth terminal of the processing module, its second terminal connected to the second terminal of the current detection module, and its third terminal connected to the AC / DC converter, is used to supply power to the multiple peripheral interfaces, the processing module, the current detection module, the data detection module, and the wireless charging module; and

[0014] The power supply control module has a first terminal connected to the third terminal of the current detection module and a second terminal connected to the fourth terminal of the power supply module. The power supply control module is used to control the power supply output of the power supply module according to the second detection signal, thereby controlling the transmission of the output current.

[0015] In the first aspect of this disclosure, the monitoring module can monitor the connection status of multiple peripheral interfaces in real time. Furthermore, when the monitoring module detects that a peripheral interface is connected, the data detection module and the current detection module can respectively detect the working status of the output data and output current lines in the peripheral interface. Based on the working status of the output data and output current lines, the data transmission control module and the power supply control module control the transmission of current and data output from the processing module to the peripheral interface. In this case, when the peripheral interface is idle, the power consumption of internal components such as the processing module of the expansion dock can be effectively reduced. After the peripheral interface is connected, by controlling the transmission status of the output current and output data, the power consumption of the expansion dock can be further reduced, and the service life of the expansion dock can be extended.

[0016] Additionally, in the low-power docking station disclosed in the first aspect of this invention, optionally, the wireless charging module further includes a proximity sensor connected to the power supply module, wherein the power supply module powers on the wireless charging module after the proximity sensor detects the proximity of the peripheral device. This further reduces the power consumption of the wireless charging module.

[0017] Furthermore, in the low-power docking station disclosed in the first aspect of this invention, optionally, the plurality of peripheral interfaces are at least one of a driver interface, a display interface, a keyboard interface, a printer interface, a scanner interface, a USB flash drive interface, a hard disk interface, a projector interface, and a mobile phone interface. This enriches the variety of peripheral interfaces.

[0018] Additionally, in the low-power expansion dock involved in the first aspect of this disclosure, optionally, the monitoring signal includes an access signal and an unaccessed signal. When a peripheral device is connected to multiple peripheral interfaces, the monitoring module generates the access signal; when a peripheral device is not connected to multiple peripheral interfaces, the monitoring module generates the unaccessed signal.

[0019] Furthermore, in the low-power expansion dock according to the first aspect of this disclosure, optionally, the first detection signal includes a first on signal and a first off signal. When the monitoring module detects that the peripheral device is connected and needs to transmit the output data, the data detection module generates the first on signal based on the access signal. When the monitoring module detects that the peripheral device is not connected, the data detection module generates the first off signal based on the off signal. The data transmission control module controls the processing module to transmit the output data to the peripheral interface based on the first on signal, and the data detection module controls the processing module to interrupt the transmission of the output data to the peripheral interface based on the first off signal. This allows for convenient control of the output data transmission status.

[0020] Additionally, in the low-power expansion dock according to the first aspect of this disclosure, optionally, the second detection signal includes a second on signal and a second off signal. When the monitoring module detects that the peripheral device is connected and needs to transmit the output current, the current detection module generates the second on signal based on the connection signal. When the monitoring module detects that the peripheral device is not connected, the current detection module generates the second off signal based on the off signal. The power supply control module controls the power supply module to continuously transmit the output current to the processing module based on the second on signal, and controls the power supply control module to interrupt the transmission of the output current to the processing module based on the off signal.

[0021] Furthermore, in the low-power expansion dock according to the first aspect of this disclosure, optionally, the power supply module includes a voltage conversion module and a current limiting module, which are connected in sequence. This facilitates the conversion and output of power supply voltage and current.

[0022] A second aspect of this disclosure provides a power consumption monitoring method for a low-power expansion dock, the low-power expansion dock including multiple peripheral interfaces, comprising the following steps:

[0023] The monitoring module monitors whether peripheral devices are connected to the peripheral interface and generates monitoring signals;

[0024] When the monitoring module detects the connection of a peripheral device, the data detection module checks whether the peripheral interface is transmitting output data and generates a first detection signal; simultaneously

[0025] The current detection module detects whether the peripheral interface is transmitting output current and generates a second detection signal;

[0026] The data transmission control module controls the transmission of the output data in the processing module according to the first detection signal; and

[0027] The power supply control module controls the transmission of the output current in the power supply module and the processing module according to the second detection signal.

[0028] In the second aspect of this disclosure, after being connected to a terminal or plugged into a power source, each module within the docking station automatically powers on and begins operation. At this time, the monitoring module can monitor the connection status of multiple peripheral interfaces in real time. Furthermore, when the monitoring module detects that a peripheral interface is connected, the data detection module and the current detection module can respectively detect the operating status of the output data and output current lines in the peripheral interface. Based on the operating status of the output data and output current lines, the data transmission control module and the power supply control module control the transmission of current and data output from the processing module to the peripheral interface. In this case, when the peripheral interface is idle, the power consumption of internal components such as the processing module of the docking station can be effectively reduced. Furthermore, after the peripheral interface is connected, by controlling the transmission status of the output current and output data, the power consumption of the docking station can be further reduced, thereby extending the service life of the docking station.

[0029] Furthermore, in the power consumption monitoring method according to the second aspect of this disclosure, optionally, the monitoring module generates an access signal when it detects that a peripheral device is connected to the peripheral interface; the data detection module generates a first connection signal based on the access signal; the current detection module generates a second connection signal based on the current detection module; the data transmission control module controls the processing module to transmit the output data to the peripheral interface based on the first connection signal; the power supply control module controls the power supply module to continuously transmit the output current to the processing module based on the second connection signal; or, the monitoring module generates a non-access signal when it detects that no peripheral device is connected to the peripheral interface; the data detection module generates a first non-connection signal based on the non-access signal; the current detection module generates a second non-connection signal based on the non-access signal; the data transmission control module controls the processing module to interrupt the transmission of the output data to the peripheral interface based on the first non-connection signal; the power supply control module controls the power supply module to interrupt the transmission of the output current to the processing module based on the non-connection signal. This allows for convenient control of the transmission of output data and output current.

[0030] Furthermore, in the power consumption monitoring method according to the second aspect of this disclosure, optionally, a proximity sensor detects whether the peripheral device is approaching; the power supply module powers on the wireless charging module after the proximity sensor detects the peripheral device's approach. This further reduces power consumption.

[0031] In this disclosure, the monitoring module can monitor the connection status of multiple peripheral interfaces in real time. Furthermore, when the monitoring module detects that a peripheral interface is connected, the data detection module and the current detection module can respectively detect the working status of the output data and output current lines in the peripheral interface. Based on the working status of the output data and output current lines, the data transmission control module and the power supply control module control the transmission of current and data output from the processing module to the peripheral interface. In this case, when the peripheral interface is idle, the power consumption of internal components such as the processing module of the expansion dock can be effectively reduced. After the peripheral interface is connected, by controlling the transmission status of output current and output data, the power consumption of the expansion dock can be further reduced, and the service life of the expansion dock can be extended.

Detailed Implementation

[0042] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or the shapes of the components may differ from actual figures.

Figure 4 This is a functional block diagram illustrating a wireless charging module according to an embodiment of the present disclosure.

[0044] Reference Figures 1 to 4 The low-power expansion dock 1 (hereinafter referred to as expansion dock 1) involved in this embodiment may include a processing module 10, a wireless charging module 20, a monitoring module 30, a power supply module 40, a power supply control module 50, a data transmission control module 60, a peripheral interface 70, and a bus interface 80.

[0045] The expansion dock 1 can connect to the terminal 3 through the bus interface 80 and obtain the input current and input data from the terminal 3. The expansion dock 1 can connect to the peripheral device 2 through the peripheral interface 70 and transmit the output current and output data to the peripheral device 2. Of course, the peripheral device 2 can also be used as an input device such as a mouse or keyboard to control the terminal through the expansion dock 1.

[0046] The docking station involved in this embodiment can also be charged by plugging in an external power source using a power cord to provide power to the power supply module 40 and the wireless charging module 20.

[0047] Specifically, in this embodiment, the wireless charging module 20 may include a wireless electromagnetic induction charging base 250, a high-frequency transmitting module 230 disposed on one side of the wireless electromagnetic induction charging base 250, a frequency converter 220 connected to the high-frequency transmitting module 230, and an AC / DC converter 210 connected to the frequency converter 220. The processing module 10 has a first end connected to the bus interface 80 and a second end connected to multiple peripheral interfaces 70. The processing module 10 is used to decode, transcode, and distribute input data to the multiple peripheral interfaces 70. The monitoring module 30 may include a data detection module 320 and a current monitoring module 310. The monitoring module is connected to the multiple peripheral interfaces 70 to monitor whether any peripheral devices are connected to the multiple peripheral interfaces 70 and to generate corresponding monitoring signals. The data detection module 310 has a first end connected to the multiple peripheral interfaces 70. The data detection module 310 is used to detect whether the output data lines in the peripheral interfaces 70 are working and to generate a first detection signal. The data transmission control module 60 has its first terminal connected to the third terminal of the processing module 10, and its second terminal connected to the second terminal of the data detection module 320. The data transmission control module 60 controls the transmission of output data from the processing module 10 based on a first detection signal. The current detection module 310 has its first terminal connected to multiple peripheral interfaces 70. The current detection module 310 detects whether the output current lines in the multiple peripheral interfaces 70 are working and generates a second detection signal. The power supply module 40 has its first terminal connected to the fourth terminal of the processing module 10, its second terminal connected to the second terminal of the current detection module 310, and its third terminal connected to the AC / DC converter 210. The power supply module 40 provides power to the multiple peripheral interfaces 70, the processing module 10, the current detection module 310, the data detection module 320, and the wireless charging module 20. The first terminal of the power supply control module 50 is connected to the third terminal of the current detection module 310, and the second terminal of the power supply control module 50 is connected to the fourth terminal of the power supply module 40. The power supply control module 50 is used to control the power supply output of the power supply module 40 according to the second detection signal, thereby controlling the transmission of the output current.

[0048] In this embodiment, the monitoring module 30 can monitor the connection status of multiple peripheral interfaces 70 in real time. Furthermore, when the monitoring module 30 detects that a peripheral interface 70 is connected, the data detection module 320 and the current detection module 310 can respectively detect the working status of the output data and output current lines in the peripheral interface 70. Based on the working status of the output data and output current lines, the data transmission control module 60 and the power supply control module 50 control the transmission of current and data output from the processing module 10 to the peripheral interface 70. In this case, when the peripheral interface 70 is idle, the power consumption of the internal components of the expansion dock, such as the processing module, can be effectively reduced. And after the peripheral interface 70 is connected, by controlling the transmission status of the output current and output data, the power consumption of the expansion dock can be further reduced, and the service life of the expansion dock can be extended.

[0049] In this embodiment, the wireless charging module 20 may further include a proximity sensor 240 connected to the power supply module 40. The power supply module 40 powers on the wireless charging module 20 after the proximity sensor 240 detects that a peripheral device is nearby. In this case, when no peripheral device is nearby for charging, the wireless charging module 20 is in a power-off or standby state, thereby further reducing the power consumption of the docking station 1.

[0050] In some examples, terminal 3 can be a computer, tablet, or mobile phone. After terminal 3 is connected to docking station 1, terminal 3 provides plug-and-play power and drivers to the docking station, thereby enabling the modules within docking station 1 to start working.

[0051] In some examples, the multiple peripheral interfaces 70 can be at least one of the following: drive interface, monitor interface, keyboard interface, printer interface, scanner interface, USB flash drive interface, hard drive interface, projector interface, audio interface, mobile phone interface, and tablet interface. This enriches the variety of peripheral interfaces and improves the applicability of the docking station 1.

[0052] Figure 5 This is a schematic diagram of a module illustrating an example of a low-power docking station according to an embodiment of the present disclosure. Figure 6 This is a functional block diagram illustrating an example of a monitoring module involved in an embodiment of this disclosure.

[0053] Reference Figure 5 and Figure 6In this embodiment, the processing module 10 may include a video data processing module, an audio data processing module, a graphic data processing module, and a current processing module. The power supply module 30 can be connected to the current processing module, and the data detection module 320 can be connected to the video data processing module, the audio data processing module, and the graphic data processing module, respectively. Therefore, the processing module 10 can conveniently process current, video, audio, graphic, and other data, and each data processing module can simultaneously handle the decoding, transcoding, and distribution of video, audio, and graphic data.

[0054] It is understandable that the same peripheral interface 70 can often have the functions of data transmission and charging at the same time. The current detection module 310 and the data detection module 320 of this application can detect the current and data transmission status in the peripheral interface respectively, and further control the working status of the current processing module and the data transmission control module 60 in the processing module 10 through the power supply control module 50 and the data transmission control module 60, thereby achieving the purpose of reducing power consumption.

[0055] As an example, in this embodiment, the data line used to connect to the peripheral interface 70 may include multiple signal lines, such as VBUS, TX, RX, D+, D-, GND, CC1, CC2, etc. VBUS is a power line, TX and RX are signal lines for transmitting data, D+ and D- are differential data line pairs, GND is a ground line, and CC1 and CC2 are signal lines used to confirm the insertion direction and the data transmission direction. Correspondingly, the peripheral interface 70 and the processing module 10 have modules for connecting and processing the corresponding signal lines. For example, in this embodiment, the connection to VBUS is a branch of the current processing module (responsible for charging), and the connection to TX and RX is a branch of the data processing module. When the connected peripheral device 2 only needs to be charged, the data processing function in the processing module 10 can be turned off through the above embodiments of this embodiment; when the connected peripheral device 2 only needs to transmit data, the current processing function in the processing module 10 can be turned off through the above embodiments of this embodiment, thereby reducing power consumption.

[0056] In this embodiment, different data processing modules can be provided on the interface depending on the type of peripheral interface 70. In some examples, a video data processing module can be provided on the display interface or projector interface, an audio data processing module can be provided on the speaker interface, a graphic data processing module can be provided on the printer interface, and a current processing module and the above-mentioned data processing modules can be provided on the interface for charging peripheral devices, such as a mobile phone interface. In addition, in some examples, at least two of the video data processing module, audio data processing module, graphic data processing module, and current processing module can be provided on the same interface, thereby enabling the processing of multiple types of data on a single interface.

[0057] In this embodiment, when the peripheral interface 70 is connected to peripheral devices 2 such as mobile phones and tablets, it can both charge the mobile phones and tablets and transmit data with them. At this time, the current detection module 310 and the data detection module 320 can detect the current and data transmission status. For example, when only current transmission is needed (the device is in charging state), the data processing work in the processing module 10 can be turned off, and when only data transmission is needed (the device is in data transmission state), the current processing work in the processing module can be turned off or partially turned off, thereby reducing power consumption.

[0058] In this embodiment, the monitoring signal includes an access signal and an unaccessed signal. When a peripheral device 2 is connected to multiple peripheral interfaces 70, the monitoring module 30 generates an access signal. When no peripheral device 2 is connected to multiple peripheral interfaces 70, the monitoring module 30 generates an unaccessed signal.

[0059] In this embodiment, the first detection signal includes a first on signal and a first off signal. When the monitoring module 30 detects that the peripheral device 2 is connected and needs to transmit output data, the data detection module 320 generates a first on signal based on the on signal. When the monitoring module 30 detects that the peripheral device 2 is not connected, the data detection module 320 generates a first off signal based on the off signal. The data transmission control module 60 controls the processing module 10 to transmit output data to the peripheral interface 70 based on the first on signal, and the data detection module 320 controls the processing module 10 to interrupt the transmission of output data to the peripheral interface 70 based on the first off signal. This allows for convenient control of the output data transmission status.

[0060] In this embodiment, the second detection signal includes a second on signal and a second off signal. When the monitoring module 30 detects that the peripheral device 2 is connected and needs to transmit output current, the current detection module 310 generates a second on signal based on the connection signal. When the monitoring module 30 detects that the peripheral device 2 is not connected, the current detection module 310 generates a second off signal based on the off signal. The power supply control module 50 controls the power supply module 40 to continuously transmit output current to the processing module 10 based on the second on signal, and controls the power supply module 40 to interrupt the transmission of output current to the processing module 10 based on the off signal.

[0061] In some examples, when the monitoring module 30 detects that any one or more of the multiple peripheral interfaces 70 are connected to the peripheral device 2, it will feed back the generated access signal to the current detection module 310 and the data detection module 320, which will then control the transmission of current and data based on the detection results.

[0062] In this embodiment, the plurality of peripheral interfaces 70 may include a first peripheral interface 710, a second peripheral interface 720, and a third peripheral interface.

[0063] In some examples, the video data processing module can be connected to the first peripheral interface 710, the audio data processing module to the second peripheral interface 720, and the image and text data processing module to the third peripheral interface. The monitoring module 30 can be connected to the first peripheral interface 710, the second peripheral interface 720, and the third peripheral interface respectively, and the power supply module 30 can be connected to the first peripheral interface 710, the second peripheral interface 720, and the third peripheral interface 730 respectively. The monitoring module 30 can monitor the connection status of the first peripheral interface 710, the second peripheral interface 720, and the third peripheral interface respectively, and generate corresponding access signals or non-access signals. In this case, it is convenient to monitor the connection status of each peripheral interface separately, while reducing the power consumption of peripheral interfaces without connected peripheral devices and their corresponding processing modules, thereby further reducing the power consumption of the docking station.

[0064] The above provides an example with three peripheral interfaces and three corresponding types of processing modules, but it is not limited to this. See details for further information. Figure 4 The peripheral interface 70 may include a first peripheral interface, a second peripheral interface 720, ..., an nth peripheral interface 7n0, etc. The data processing module 10 may include a first data processing module 111, a second data processing module 112, ..., an nth data processing module 11n, etc. Correspondingly, the peripheral device 2 may include a first peripheral device 21, a second peripheral device 22, ..., an nth peripheral device 2n, etc. In this case, the detection module 20 can monitor the connection status of each of the n peripheral interfaces and generate a corresponding access signal Y or non-access signal N. For example, when monitoring the connection status between the first peripheral interface 710 and the first peripheral device 21, an access signal Y1 or a non-access signal N1 can be generated, ... when monitoring the connection status between the nth peripheral interface 710 and the nth peripheral device 21, an access signal Yn or a non-access signal Nn can be generated, etc., and so on. Examples are not listed here. Therefore, the connection status of each interface can be easily and fully monitored, and the interfaces connected to peripheral devices and their corresponding data processing modules can be powered on normally and perform data processing and transmission, while the interfaces not connected to peripheral devices and their corresponding data processing modules can be powered off and their data processing and transmission interrupted. Thus, the power consumption of the docking station 1 can be reduced in one step.

[0065] Furthermore, when the monitoring module 30 detects that a peripheral device 2 is connected to a certain interface, the current detection module 310 and the data detection module 320 can be used to further determine the current and data transmission status. Subsequently, the power supply control module 50 and the data transmission control module 60 control the working status of current processing and data processing in the power supply module 40 and the processing module 10 respectively. This can further reduce power consumption.

[0066] Refer again Figure 5 In this embodiment, the power supply module 30 may include voltage conversion modules 311, 312, ..., 31n, and current limiting modules 321, 322, ..., 32n. Each voltage limiting module can be connected sequentially to its corresponding current limiting module and to its corresponding data processing module. That is, voltage conversion module 311, current limiting module 321, first data processing module 111, and first peripheral interface can be connected sequentially... voltage conversion module 31n, current limiting module 32n, nth data processing module 11n, and nth peripheral interface can be connected sequentially. Each current limiting module can be connected to the power supply control module 40. The voltage conversion module can be implemented using devices such as voltage converters, which can be used for voltage conversion and output; the current limiting module can be implemented using devices such as current limiters, which can be used to control the on / off state of the power supply current on the corresponding branch or reduce the output of the power supply current under the control of the power supply control module 40.

[0067] Reference Figure 6 In some examples, the monitoring module 30 may include a pin level monitoring module 330 and a monitoring result output module 340, which can be connected sequentially. The pin level monitoring module 330 can be used to monitor the high and low levels of the peripheral interface pins, that is, to monitor the reset state of the peripheral interface pins. When the peripheral interface pin is reset, the pin level monitoring module 330 detects a low level, meaning that the peripheral interface is not connected to a peripheral device at this time; when the peripheral interface pin is set, the pin level monitoring module 330 detects a high level, meaning that the peripheral interface is connected to a peripheral device at this time. This allows for convenient monitoring of the connection status of the peripheral interface.

[0068] In other examples, the monitoring module 30 can be configured with a multi-channel pin level monitoring module 330 and a monitoring result output module 340 corresponding to multiple peripheral interfaces 70. This allows for convenient and comprehensive monitoring of the connection status of each peripheral interface.

[0069] In this embodiment, the monitoring module 30, current detection module 310, and data detection module 320 are in a hierarchical relationship. That is, the monitoring module 30 can first determine whether the peripheral device 2 is connected by monitoring the high and low voltage levels of the peripheral interface pins. If the peripheral device 2 is connected, the current detection module 310 and data detection module 320 then detect the transmission status of current and data.

[0071] Reference Figure 7 This disclosure also provides a power consumption monitoring method for a low-power expansion dock 1, which includes multiple peripheral interfaces 70.

[0072] The method may include the following steps:

[0073] In step S100, the monitoring module 30 monitors whether multiple peripheral interfaces 70 are connected to peripheral devices 2 and generates monitoring signals;

[0074] In step S200, the power supply control module 40 controls the power supply output of the power supply module 30 according to the monitoring signal, thereby realizing the power supply control of the processing module 10 and multiple peripheral interfaces 70.

[0075] In this disclosure, after the expansion dock 1 is connected to the terminal 3, each module in the expansion dock 1 will automatically power on and start working. At this time, the monitoring module 30 can monitor the connection status of multiple peripheral interfaces 70 in real time, and control the power supply module 30 to supply power to the processing module 10 and multiple peripheral interfaces 70 according to the connection status. In this case, when the peripheral interfaces 70 are idle, the power consumption of the internal components of the expansion dock 1, such as the processing module 10, can be effectively reduced, and the service life of the expansion dock can be extended.

[0076] In some examples, step S200 may also include step S210 (monitoring module 30 generates an access signal) and step S220 (monitoring module 30 generates an unaccessed signal).

[0077] In step S210, when the monitoring module 30 generates an access signal;

[0078] In step S211, the data detection module 320 generates a first detection signal; simultaneously, in step S212, the current detection module 310 generates a second detection signal; and then...

[0079] In step S221, the data transmission control module controls the transmission of output data;

[0080] In step S222, the power supply control module controls the transmission of the output current.

[0081] In some examples, step S300 involves the power supply module 30 interrupting the output of voltage and current to the processing module 10 based on the unconnected signal.

[0082] Specifically, in this embodiment, the monitoring module 30 generates an access signal (step S210) when it detects that a peripheral device 2 is connected to the peripheral interface 70; the power supply control module 40 can control the power supply module 30 to continuously output power supply voltage and current to the processing module 10 according to the access signal. Alternatively, the monitoring module 30 generates a no-access signal (step S220) when it detects that no peripheral device 2 is connected to the peripheral interface 70; the power supply control module 40 can control the power supply module 30 to interrupt the output of voltage and current to the processing module 10 according to the no-access signal. Thus, the operating status of the processing module 10 and multiple peripheral interfaces 70 can be easily controlled according to the access signal and the no-access signal.

[0083] Furthermore, when the monitoring module detects the connection of a peripheral device, the data detection module 320 detects whether the peripheral interface 70 is transmitting output data and generates a first detection signal; simultaneously

[0084] The current detection module 310 detects whether the peripheral interface 70 is transmitting output current and generates a second detection signal;

[0085] The data transmission control module 60 controls the transmission of output data from the processing module 10 according to the first detection signal; and

[0086] The power supply control module 50 controls the transmission of output current in the power supply module 40 and the processing module 10 according to the second detection signal.

[0087] In this disclosure, after being connected to a terminal or plugged into a power source, all modules within the docking station automatically power on and begin operation. At this time, the monitoring module 30 can monitor the connection status of multiple peripheral interfaces 70 in real time. Furthermore, when the monitoring module 30 detects that a certain peripheral interface is connected, the data detection module 320 and the current detection module 310 can respectively detect the working status of the output data and output current lines in the peripheral interface. Based on the working status of the output data and output current lines, the data transmission control module 60 and the power supply control module 50 control the transmission of current and data output from the processing module to the peripheral interface. In this case, when the peripheral interface is idle, the power consumption of internal components such as the processing module of the docking station can be effectively reduced. Furthermore, after the peripheral interface is connected, by controlling the transmission status of the output current and output data, the power consumption of the docking station can be further reduced, and the service life of the docking station can be extended.

[0088] In this embodiment, when the monitoring module 30 detects that the peripheral interface 70 is connected to the peripheral device 2, it generates an access signal; the data detection module 320 generates a first connection signal based on the access signal; the current detection module 310 generates a second connection signal based on the current detection module; the data transmission control module 60 controls the processing module 10 to transmit output data to the peripheral interface 70 based on the first connection signal; and the power supply control module 50 controls the power supply module 40 to continuously transmit output current to the processing module 10 based on the second connection signal. Alternatively, when the monitoring module 30 detects that the peripheral interface 70 is not connected to the peripheral device 2, it generates a non-access signal; the data detection module 320 generates a first non-connection signal based on the non-access signal; the current detection module 310 generates a second non-connection signal based on the non-access signal; the data transmission control module 60 controls the processing module 10 to interrupt the transmission of output data to the peripheral interface 70 based on the first non-connection signal; and the power supply control module 50 controls the power supply module 40 to interrupt the transmission of output current to the processing module 10 based on the non-connection signal. This allows for convenient control of the transmission of output data and output current.

[0089] In this embodiment, the proximity sensor 240 detects whether the peripheral device 2 is nearby; the power supply module 40 powers on the wireless charging module 20 after the proximity sensor 240 detects the proximity of the peripheral device 2. This further reduces power consumption when the peripheral device 2 is not in use.

[0090] In this embodiment, the monitoring module 30 can monitor the connection status of multiple peripheral interfaces 70 in real time. Furthermore, when the monitoring module 30 detects that a peripheral interface 70 is connected, the data detection module 320 and the current detection module 310 can respectively detect the working status of the output data and output current lines in the peripheral interface 70. Based on the working status of the output data and output current lines, the data transmission control module 60 and the power supply control module 50 control the transmission of current and data output from the processing module 10 to the peripheral interface 70. In this case, when the peripheral interface 70 is idle, the power consumption of the internal components of the expansion dock, such as the processing module, can be effectively reduced. And after the peripheral interface 70 is connected, by controlling the transmission status of the output current and output data, the power consumption of the expansion dock can be further reduced, and the service life of the expansion dock can be extended.
