[0091]In the first embodiment of the present invention, the method includes the following steps:

[0092]Step S501: When the first data interface 101a is connected to the mobile terminal 20a, the access status of the second data interface 102a and the third data interface 103a are monitored.

[0093]Specifically, the first data interface 101a is used to access the mobile terminal 20a. The second data interface 102a is used to access the OTG device 30A, so that the mobile terminal 20a can perform output transmission with the OTG device 30A through the first data interface 101a and the second data interface 102a. The second data interface 102a is used to connect to the charging device 40a, so that the charging device 40a can charge the mobile terminal 20a through the first data interface 101a and the third data interface 103a. When the first data interface 101a is connected to the mobile terminal 20a, the connection status of the second data interface 102a and the third data interface 103a ...

Abstract

The invention discloses a data line, which comprises: a first data interface, a second data interface, a third data interface, a switching unit and a control unit. The first data interface is used to access the mobile terminal, the second data interface is used to access the OTG device, and the third data interface is used to access the charging device. The switching unit is electrically connected to the first data interface, the second data interface and the third data interface. The control unit is electrically connected to the first data interface, the second data interface, the third data interface and the switching unit, and is used for accessing the mobile terminal according to the second data interface and the third data interface when the first data interface is connected to the mobile terminal. The state control switching unit connects the first data interface and the second data interface or selectively connects the first data interface and the third data interface. The present invention also provides a data transmission method. The above scheme enables the mobile terminal to select charging or data transmission or data transmission while charging through the data line.

Description

Technical field[0001]The invention relates to the field of charging and data transmission, in particular to a data cable and a data transmission method.Background technique[0002]With the development of technology, smart mobile terminals have become necessities for work and entertainment, and the data cable is a bridge connecting smart mobile terminals for charging and data transmission. However, the current data cables on the market basically have a single function, which can only be connected to a smart mobile terminal to charge or perform OTG (On The Go) function, that is, when the mobile terminal is using OTG function (data transmission), it does not support the charging function, or The mobile terminal does not support the use of OTG function (data transmission) during the charging process.Summary of the invention[0003]In view of this, the present invention proposes a data line and a data transmission method to solve the above technical problems.[0004]First of all, in order to a...
