Description
Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a USB connection line, an operation method based on the USB connection line, and a mobile terminal.
Background
Universal Serial Bus (USB) was a standard established by the nonprofit organization in 1994, consisting of microsoft, intel, International Business Machines (IBM), etc., and was originally intended to help external devices better connect and exchange data with computers. Over the course of more than 20 years, the USB standard has undergone multiple versions ranging from 1.x, 2.0, 3.0 to 3.1, with significant advances in data transfer rates. The C-Type USB (USB Type-C, abbreviated as USB-C) is a specification of a new USB cable and connector, and defines a whole set of new USB physical specifications including a connector, a port, a container, a cable, and the like.
The USB-C interface has the bright points of thinner design, higher transmission speed (highest 10Gbps) and stronger power transmission (highest 100W), and has the biggest characteristic of supporting the double-sided insertion of the USB interface, formally solving the problem of inaccurate USB insertion, and the convenient insertion of the front side and the back side, thereby greatly improving the usability of the USB interface. Since the interface has no directivity and the size of the interface is small, only 8.3mm by 2.5mm, more and more mobile phones start to use the USB-C interface as the USB interface.
The USB-C is part of a USB 3.1 interface, and compared with the USB2.0, the USB-C interface comprises four newly added lines SSTX +, SSTX-, SSRX +, SSRX-in the USB 3.0. However, since many mobile phones do not use USB 3.0, these pins on the interface are idle, which inevitably results in waste of resources and reduces the efficiency of interface usage.

Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1 is a block diagram illustrating a USB connection line according to an exemplary embodiment, where the USB connection line includes, as shown in fig. 1: the cable body 11 is provided with a first USB interface 12 and a second USB interface 13 which are positioned at one end of the cable body 11; a third USB interface 14 located at the other end of the wire body 11; the versions of the first USB interface and the second USB interface are lower than that of the third USB interface, and the first USB interface or the second USB interface is used for multiplexing idle data lines of the third USB interface.
As shown in fig. 2, the wire body 11 may include a main wire body 111 connected to the third USB interface 14, a first secondary wire body 112 connected to the first USB interface 12, and a second secondary wire body 113 connected to the second USB interface 13, wherein the main wire body 111 is connected to the first secondary wire body 112 and the second secondary wire body 113, respectively.
The first USB interface and the second USB interface may be different interfaces or the same interface, for example, both may be USB2.0 interfaces, and the version of the third USB interface is higher than the versions of the first USB interface and the second USB interface, for example, may be a C-type USB interface. It should be noted that the above is only an example, and does not limit the specific interface type.
The structure and the use of the USB cable will be described in detail below by taking as an example that the first USB interface and the second USB interface are both USB2.0 interfaces, and the third USB interface is a C-type USB interface.
Because the main line body is internally provided with the D +, D-, SSTX +, SSRX + and SSRX-data lines connected with the C-type USB interface, when the C-type USB interface is only used as a USB2.0 interface, only the D + and D-data lines of the USB2.0 are used, and thus the SSTX +, SSRX and SSRX-data lines are idle and can be used for transmitting four data signals at most. In this embodiment, if the first USB interface uses D + and D-data lines, the second USB interface may multiplex part or all of SSTX +, SSTX-, SSRX +, and SSRX-, that is, the first auxiliary line body is provided with D + and D-data lines connected to the first USB interface, and the second auxiliary line body is provided with part or all of SSTX +, SSTX-, SSRX +, and SSRX-connected to the second USB interface; similarly, if the second USB interface uses D + and D-data lines, the first USB interface may multiplex part or all of SSTX +, SSTX-, SSRX +, and SSRX-, that is, part or all of SSTX +, SSTX-, SSRX +, and SSRX-connected to the first USB interface is provided in the first sub-line body, and D + and D-data lines connected to the second USB interface are provided in the second sub-line body.
The main line body 111 shown in fig. 2 conforms to the specification of USB 3.0, and the first secondary line body 112 and the second secondary line body 113 both conform to the specification of USB 2.0.
In this embodiment, when the first USB interface 12 multiplexes some or all of the SSTX +, SSTX-, SSRX +, SSRX-of the third USB interface 14, a signal conversion chip 121 may be disposed in the first USB interface 12, as shown in fig. 3; similarly, when the second USB interface 13 multiplexes some or all of SSTX +, SSTX-, SSRX +, SSRX-of the third USB interface 14, a signal conversion chip 131 may be disposed in the second USB interface 13, as shown in fig. 4.
When two of the four idle data lines are multiplexed as a UART interface, a conversion chip (e.g., PL2303) for converting USB and Universal Asynchronous Receiver/Transmitter (UART) and a peripheral circuit are required to be disposed in the corresponding USB interface, so as to convert the USB signal into a corresponding UART signal. When four idle data lines are used as Joint Test Action Group (JTAG) debug interfaces, a Micro Control Unit (MCU) needs to be set in the corresponding USB interface, and programmed therein to convert USB signals into corresponding JTAG signals.
In addition, the first, second and third USB interfaces are male interfaces, the male interface is opposite to the female interface, and the male interface generally refers to an interface into which other devices can be inserted. The first and second USB interfaces are A-type male interfaces and can be connected with a host computer such as a PC, and the third USB interface can be connected with a mobile terminal such as a mobile phone.
In this embodiment, after the user connects the third USB interface to the mobile phone, if only the first USB interface in fig. 4 is connected to the PC, the normal data operation and charging of USB2.0 can be realized; if only the second USB interface in fig. 4 is connected to the PC, the mobile phone cannot be charged, and only data can be transmitted based on the multiplexed data line, for example, test data of a mobile phone chip, log data of a program in the mobile phone, and the like; if the first USB interface and the second USB interface are connected to the PC, normal USB2.0 operation and charging can be achieved, and data can be transmitted based on the multiplexed data lines, wherein the data includes but is not limited to test data and log data.
According to the USB connecting line, the idle data line of the third USB interface is multiplexed through the first USB interface or the second USB interface, the use efficiency of the third USB interface is improved, in addition, an additional interface does not need to be added to the mobile terminal connected with the third USB interface, and the cost of the mobile terminal can be reduced.
Fig. 5 is a flowchart illustrating an operation method based on a USB connection line according to an exemplary embodiment, where the structure of the USB connection line may refer to fig. 1, which is not described herein, and in this embodiment, it is assumed that the second USB interface multiplexes a spare data line of the third USB interface, as shown in fig. 5, the method includes:
in step S501, it is determined whether the mobile terminal is successfully connected to the third USB interface and the host is successfully connected to the second USB interface.
The mobile terminal can be a mobile phone, and the host can be a PC.
In this embodiment, a mobile terminal such as a mobile phone can determine whether the mobile terminal is connected to a PC through a first USB interface or a second USB interface of a USB connection line.
In step S502, when it is determined that the mobile terminal is successfully connected to the third USB interface and the host is successfully connected to the second USB interface, data including test data is transmitted based on the multiplexed data line.
If the mobile terminal such as a mobile phone judges that the mobile terminal is connected with the PC through the second USB interface, data can be transmitted based on the multiplexed data line, and the data comprises test data.
In this embodiment, a signal conversion chip may be disposed in the second USB interface, as shown in fig. 4. The multiplexed data line can be used as a UART interface, so the transmitted data can be test data, log data and other various data, and in addition, the multiplexed data line can also be used as a JTAG debugging interface, so the test data, for example, the test data of an internal chip arranged on a mobile phone and the like can be transmitted.
In addition, after determining that the mobile terminal is successfully connected to the third USB interface and the host is not successfully connected to the second USB interface, or after transmitting data based on the multiplexed data lines, the method may further include steps S503 to S504.
In step S503, it is determined whether the mobile terminal is successfully connected to the third USB interface and the host is successfully connected to the first USB interface.
In step S504, when it is determined that the mobile terminal is successfully connected to the third USB interface and the host is successfully connected to the first USB interface, the mobile terminal is charged and/or data transmission is performed with the host through the host.
In this embodiment, the first USB interface corresponds to a conventional USB2.0 interface.
The operation method based on the USB connecting line can be operated based on the USB connecting line provided by the disclosure, and an additional interface does not need to be added to the mobile terminal connected with the connecting line, so that the cost of the mobile terminal can be reduced.
