Problems solved by technology

Usually, the docking station can provide multiple external device interfaces. If some of the external device interfaces are not connected to the corresponding external devices, for example, the monitor or speaker is not actually connected, it means that the user does not want to use the docking station to display images. Display or play sound, and may only want to use other ports on the docking station (such as network port, serial port, etc.), but at this time the audio and video data processing module of the docking station has already started processing audio and video data from the host computer, resulting in Unnecessary waste of power, especially when the dock is powered by USB

no. 1 example

[0042] In this embodiment, the description will be made by taking the external device as an example of a display. At this time, the external device monitoring module is specifically a display monitoring module, and the external device data processing module related to the display in the docking station includes a video interface module and Video data processing module, etc.

[0043] Such as figure 2 As shown, the docking station 22 in this embodiment includes:

[0044]A display interface 223, used for connecting an external display 23;

[0045] The video interface module 221 is connected to the host computer 21 by wireless or wired means, and is used to receive video data from the host computer; wherein, figure 2 The wired method shown in may be connected by a USB cable, and the wireless method may be connected by a wireless USB (WUSB, Wireless USB). Of course it can be figure 2 Various other existing wireless communication methods not shown in , such as connecting thro...

no. 2 example

[0067] In this embodiment, the description is still made by taking that the external device is a display as an example.

[0068] Figure 6 Shown is the computer docking station provided by this embodiment, similar to the first embodiment, Figure 6It includes: a host 51, a docking station 52 and a display 53, and the host computer 51 includes a USB interface 511; The above modules have the same functions as the corresponding modules in the first embodiment. The difference between this embodiment and the first embodiment is that in this embodiment, the display interface 523 supports a built-in integrated circuit (I 2 C, Inter-Integrated Circuit) bus protocol, between the display interface 523 and the display monitoring module 524 through I 2 C bus connection. Such as Figure 6 As shown, the display interface 523 and the display monitoring module 524 and the external display are all connected to the I 2 on the C bus. I 2 The C bus includes two signal lines, a serial data...

[0079] In this embodiment, the description will be made by taking the external device as an example of a speaker. At this time, the external device monitoring module is specifically a speaker monitoring module, and the external device data processing module related to the display in the docking station includes an audio interface module and Audio data processing module, etc.

[0080] Figure 7 It includes: a host 71, a docking station 72 connected to the host by wireless or wired means, and a speaker 73.

[0081] Described computer docking station 72 specifically comprises:

[0082] Speaker interface 723, used to connect external speaker 73;

[0083] an audio interface module 721, configured to receive audio data from the host;

[0084] The audio data processing module 722 is used to process the audio data received by the audio interface module 721 and output it to the speaker interface 723, so as to be provided to the speaker 73 connected to the speaker interface 723 for p...

Abstract

The invention provides a computer system, a computer docking station and a power consumption management method thereof, wherein the computer docking station comprises a computer host interface, a first group of interfaces, a second group of interfaces, a first processing module, a second processing module, a monitoring module, a power module and a control module, wherein the monitoring module is used for monitoring whether a peripheral device is connected with the interface which is connected with the monitoring module and generating monitoring result signals; the power module is used for supplying power to the computer host interface, the first group of interfaces, the second group of interfaces, the first processing module, the second processing module and the monitoring module; and thecontrol module is used for controlling the power module according to the monitoring result signals to realize power control for the first group of interfaces, the second group of interfaces, the computer host interface, the first processing module and the second processing module. According to the invention, when the docking station is not connected with any peripheral device, no power or less power is supplied to the processing module related to the peripheral device, and thus power consumption of the docking station is saved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a computer system, a computer docking station and a method for managing power consumption thereof. Background technique [0002] At present, a computer docking station (Docking Station) has become a very important extension device of a computer system, especially a portable computer system. Such as figure 1 As shown, the docking station 12 is connected to the portable computer 11 through a universal serial bus (USB, Universal Serial Bus) cable or a wireless USB (Wireless USB) mode or other interfaces or wireless protocols (such as ultra-wideband universal radio platform (WiNet), etc.) , can regenerate all input / output (I / O, Input / Output) ports on the entire computer, that is, external device interfaces, such as serial ports, parallel ports, Ethernet ports, display interfaces, microphone / speaker interfaces, etc. [0003] figure 1 The display 13 connected through the display i...
