Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, currently, some devices with a processor system perform USB data peer-to-peer or keyboard-mouse sharing with another device with a processor system by using a USB host bridge chip (USB host bridge), and the applicant finds that the USB host bridge chip can only identify the USB host device and cannot identify the USB slave device, and the USB host bridge chip cannot process data signals of the USB slave device, so that the USB interface with USB data peer-to-peer functions cannot support access of USB slave devices such as a USB disk/USB HDD disk, and the USB slave device has a single function.

In order to solve the above technical problem, the present application discloses an electronic device and a control method.

The electronic device is provided with a processor system, wherein the processor system may be, but is not limited to, a host computer system, or a simple computing processing system consisting of only a processor and its necessary peripheral components, and the electronic device may accordingly be a processor system-equipped device in a general purpose or special purpose computing device environment or configuration, such as a personal computer, server computer, hand-held or portable device, tablet-type device, single/multi-processor device (e.g., a display provided with a processor and associated components), and so forth.

The composition structure of the electronic device disclosed in the present application is shown in fig. 2, and specifically includes: a data interface 10, a switching device 20, a bridge component 30, and a master control component 40. Wherein:

and the data interface 10 is used for accessing an external device.

Illustratively, the data interface 10 may be a USB interface, such as a USB series interface of Type-A, Type-B or Type-C, or the like.

The external device accessed by the data interface 10 may be a master device with a processor system or a slave device without a processor system, and is not limited, that is, in this application, the data interface 10 supports both accessing the master device with a processor system, such as a computer, a display, and the like, and accessing the slave device without a processor system, such as a USB device, such as a USB disk, a USB HDD disk, a USB mouse/keyboard, and the like.

The switching device 20 is connected to the data interface 10, the bridge unit 30, and the main control unit 40.

In the embodiment of the present application, a switching device 20 for switching between the bridge component 30 and the main control component 40 is added to the electronic device, and the switching device 20 may be, but is not limited to, a switch or other components with an electronic control switching function, such as a USB switch (USB switch).

The bridging component 30 is connected to the data interface 10 through the exchange device 20, and is configured to perform bridging processing on the interactive data when the electronic device performs data interaction with the host device through the data interface 10.

The bridge component 30 may be, but is not limited to, a USB host bridge chip.

And the main control unit 40 is connected with the bridge unit 30 and the exchange device 20 and at least used for controlling data interaction between the electronic equipment and the external equipment.

The main control unit 40 is a host control unit of the data interface 10, and taking the data interface 10 as a USB interface as an example, the main control unit 40 may be a Platform Controller Hub (PCH) of an electronic device.

The switching device 20 is specifically configured to:

when the external device is a master device, the electrical connection between the switch device 20 and the bridge component 30 is connected, and the electrical connection between the switch device 20 and the master control component 40 is disconnected; when the external device is a slave device, the electrical connection between the switch device 20 and the master control unit 40 is made, and the electrical connection between the switch device 20 and the bridge unit 30 is broken.

Taking the switching device 20 as a USB switch, the data interface 10, the bridge component 30 and the main control component 40 as USB interfaces, USB host bridges and PCHs as examples, and referring to fig. 3, when the USB interface of the electronic device is connected to a host device such as an all-in-one machine or a display, which is provided with a processor system, the electrical connection between the USB switch and the USB host bridge is connected, and the electrical connection between the USB switch and the PCH is disconnected, so that a link of the USB interface-USB switch-USB host bridge-PCH is opened correspondingly, and the link serves as a data communication channel between the electronic device and the host device; when the USB interface of the electronic device is connected to the slave devices such as a USB flash disk, a USB key/mouse and the like, the electrical connection between the USB switch and the PCH is connected, and the electrical connection between the USB switch and the USB host bridge is disconnected, so that the link of the USB interface-USB switch-PCH is correspondingly connected and serves as a data communication channel between the electronic device and the slave devices.

By adding the exchange device 20 to the electronic device and performing the above function configuration and the connection relationship design between the exchange device and other components, when the data interface 10 with the function of data transmission and the like of the electronic device, such as a USB interface, is connected to a slave device, the electrical connection between the data interface 10 and a host control component thereof, such as a PCH, can be directly opened, and the host control component such as the PCH can effectively process the data signal of the slave device (such as a USB slave device such as a USB disk), so that the data interface 10 with the function of data transmission and the connection of the slave device such as a USB disk and a USB keyboard and mouse are supported.

Data interaction between the electronic equipment and the master end equipment or data interaction between the electronic equipment and the slave end equipment can be bidirectional, namely, the data of the external equipment can be received, and the data can be sent to the external equipment.

A host control component of the USB interface, such as a PCH, only supports data communication in a master-slave mode, and does not support data communication in the master-master mode, where the master-slave mode refers to a "master-slave device" interaction mode, and the master-master mode refers to a "master-master device" interaction mode, and in order to implement data interaction between two master devices (e.g., two computers) in the master-master mode based on the data interface 10, such as data communication based on the USB interface, keyboard and mouse sharing, the purpose of interaction in the master-master mode is achieved by using a coding and decoding bridging processing function provided by the bridging component 30 for interactive data.

Specifically, when the electronic device sends data to an external host device, the bridge component 30 encodes the first data in the slave format sent by the main control component 40 into first data in the host format, and sends the first data in the host format to the host device accessing the data interface 10 sequentially through the exchange device 20 and the data interface 10; when the electronic device receives data transmitted by the master device, the bridge component 30 obtains second data in the master format transmitted by the master device sequentially through the data interface 10 and the switching device 20, decodes the second data in the master format into second data in the slave format, and transmits the second data in the slave format to the master control component 40.

For example, assuming that the electronic device is an all-in-One machine (AIO, all in One), the host device accessed through the USB interface of the all-in-One machine is a display, in the data pairing transmission between the two devices, when the all-in-One machine sends data to the display, the PCH specifically outputs the sending data in the slave format, and the USB host bridge encodes the data into the host format and sends the encoded data to the display sequentially through the USB switch and the USB interface of the all-in-One machine; in the data receiving process opposite to the process, the USB host bridge receives the master format data sent by the display sequentially through the USB interface and the USB switch, performs decoding processing on the data, decodes the data into a slave format, and sends the decoded data to the PCH for related processing.

According to the scheme, the electronic equipment is additionally provided with the exchange devices which are respectively connected with the data interface, the bridging component and the main control component, and the additionally arranged exchange devices are configured to be connected with the bridging component and disconnected with the main control component under the condition that the external equipment is the main-end equipment, and connected with the main control component and disconnected with the bridging component under the condition that the external equipment is the slave-end equipment. By adding the exchange device and carrying out the function configuration and the design of the connection relation between the exchange device and other parts, the data interface of the electronic equipment not only supports the access of the main-end equipment with the processor system, but also supports the access of the auxiliary-end equipment without the processor system, thereby enriching the interface function of the electronic equipment and reducing the interface resource waste of the data interface.

In one embodiment, the bridge component 30 is connected to the data subinterface of the data interface 10 via the switching device 20; the bridge component 30 is directly connected to the power sub-interface of the data interface 10.

Wherein the bridge member 30 is further configured to:

identifying the device type of the external device accessed to the data interface 10 by detecting the input level signal of the power supply sub-interface of the data interface 10; and transmits a control command matching the recognized device type to the switching apparatus 20.

Specifically, the data sub-interface of the data interface 10 is a sub-interface for transmitting a data signal, the power sub-interface of the data interface 10 is a sub-interface for transmitting a power signal (e.g., an input level signal), the data sub-interface and the power sub-interface can be pins of the data interface 10 for implementing different signal transmission functions, for example, the data sub-interface can be a data + and data-data pin of the USB interface, and the power sub-interface can be a power (power) pin of the USB interface.

In the embodiment, the bridge component 30, such as a USB host bridge, is directly connected to the power supply sub-interface of the data interface 10, so that a function of determining/identifying the device type of the external device is added to the bridge component. If the bridge component 30 detects that the power supply sub-interface of the data interface 10 has an input level signal with a first threshold, it identifies the external device as the master device, and if the input level signal with a second threshold is detected, it identifies the external device as the slave device, and sends a control command matching the identified device type to the switching device 20, as shown in fig. 4.

The first threshold is different from the second threshold, and for example, the first threshold may be 5V, and the second threshold may be a voltage value other than 5V, such as 0V. Correspondingly, taking the USB host bridge as an example, when it detects that the USB power pin has a 5V level signal input, it determines that the device accessed by the USB interface is the USB host, i.e., the USB host device, whereas if it detects that the USB power pin has no 5V level signal input, it determines that the device accessed by the USB interface is the USB guest, i.e., the USB slave device.

After determining the external device type based on the level signal detection of the power subinterface of the data interface 10, the bridge component 30 further sends a control instruction matching the determined device type to the switching device 20.

The control instructions are for indicating the identified device type information and/or control type information.

The switching device 20 receives the control command sent by the bridge component 30, performs command recognition, and determines the control processing to be executed according to the device type information and/or the control type information indicated by the command, so as to control the connection and disconnection of the electrical connection between the bridge component 30 and the main control component 40.

Under the condition that the control instruction is a first control instruction matched with the type of the master-side equipment, the exchange device 20 determines a data communication channel needing to be communicated in the master-master mode through instruction identification, correspondingly connects the electric connection between the exchange device 20 and the bridging component 30, and disconnects the electric connection with the master control component 40, so that the electronic equipment is supported to perform data interaction with the master-side equipment through the data interface 10; under the condition that the control command is a second control command matched with the type of the slave-end device, the command identification is carried out to determine that a data communication channel in a master-slave mode needs to be opened, correspondingly, the electric connection between the switching device 20 and the master control unit 40 is connected, and the electric connection between the switching device 20 and the bridging unit 30 is disconnected, so that the electronic device is supported to carry out data interaction with the slave-end device through the data interface 10.

In the embodiment, the bridge component is directly connected with the power supply sub-interface of the data interface, and different level access signals are respectively designed for different types of external devices, so that the bridge component is additionally provided with a function of judging/identifying the device type of the external device based on the level access signals, based on the design, after the data interface is accessed into the external device of the corresponding type, the bridge component can be used for automatically identifying the device type and automatically opening a data communication channel matched with the device type, so as to support the data communication between the electronic device and any type (main terminal type or slave terminal type) of external device through a data interface such as a USB interface, so that the data interface not only supports the access of the main terminal device with a processor system, but also supports the access of the slave terminal device without the processor system, thereby enriching the interface function of the electronic device, the waste of interface resources of the data interface is reduced.

In addition, an embodiment of the present application further discloses a control method, which is applicable to the electronic device described above, and referring to fig. 5, the control method includes:

step 501, determining the device type of the external device accessed by the data interface of the electronic device.

Specifically, the bridge component of the electronic device may be used to detect an input level signal of the power supply sub-interface of the data interface, and identify the device type of the external device connected to the data interface based on the detected input level signal.

If the bridge component detects that the power supply sub-interface of the data interface has the input level signal with the first threshold value, the external equipment is identified as the main-end equipment; and if the input level signal of the second threshold value of the power supply sub-interface is detected, identifying the external equipment as the slave equipment.

For example, if the USB host bridge detects that the USB power pin has a 5V level signal input, it determines that the device connected to the USB interface is the USB host, i.e., the USB host device, whereas if the USB power pin does not have a 5V level signal input, it correspondingly determines that the device connected to the USB interface is the USB guest, i.e., the USB slave device.

Step 502, under the condition that the external device is a master device with a processor system, controlling a master control component of the electronic device to perform bridging processing on data through a bridging component of the electronic device, and performing data interaction with a data interface so as to perform data interaction with the accessed master device through the data interface of the electronic device.

If the external device is identified as the master device, a first control instruction matched with the type of the master device can be sent to the exchange device of the electronic device through the bridge component, so that the exchange device is connected with the electrical connection between the exchange device and the bridge component based on the instruction, the electrical connection between the exchange device and the master control component is disconnected, the master control component of the electronic device correspondingly carries out data interaction with the data interface through bridge processing (such as coding processing when sending data to the external master device and decoding processing when receiving the data of the master device) of the data through the bridge component, and further data communication between the electronic device and the external master device, such as data transmission between the electronic device and the external device, keyboard and mouse sharing and the like, is realized based on the channel.

Step 503, in the case that the external device is a slave device without a processor system, controlling the main control unit of the electronic device to directly perform data interaction with the data interface of the electronic device, so as to perform data interaction with the accessed slave device through the data interface of the electronic device.

On the contrary, if the external device is identified as the slave device, the bridge component can send a second control instruction matched with the type of the slave device to the exchange device of the electronic device, so that the exchange device is connected with the electric connection between the exchange device and the main control component based on the second control instruction, the electric connection between the exchange device and the bridge component is disconnected, the main control component of the electronic device is correspondingly connected with the data interface directly, and then the data interaction between the electronic device and the external slave device is realized through the direct connection channel.

According to the method, the exchange device is additionally arranged on the electronic equipment, and the exchange device is subjected to corresponding function configuration and connection relation design with other parts of the electronic equipment, so that the data interface of the electronic equipment not only supports access of the main-end equipment with the processor system, but also supports access of the auxiliary-end equipment without the processor system, and therefore the interface function of the electronic equipment is enriched, and interface resource waste of the data interface is reduced.
