A kind of multifunctional portable data card and data transmission method

Abstract

The invention discloses a multifunctional portable data card and a data transmitting method. The data card comprises a master control module, a gear selecting module, a data transmitting module, an interface module and a storage module, wherein the master control module detects gear selecting signals generated by the gear selecting module, and sends out corresponding operating commands to the data transmitting module according to working modes corresponding to the signals; after receiving the operating commands, the data transmitting module carries out data transmission in a data transmission module or in a connection OTG (on-the-go) data processing module; and the interface module is a port by which the data card is interactive to peripheral equipment. By the scheme, the multifunctional portable data card can be connected with a plurality of intelligent mobile terminals, supports two data transmission modes, can be simultaneously connected with a universal serial bus (USB) and a card reader interface, has multiple functions, and is small, exquisite and portable; the burden of a travelling bag of a user is reduced; and the user experience is improved.

Description

technical field [0001] The invention relates to the field of mobile Internet, in particular to a multifunctional portable data card and a data transmission method. Background technique [0002] With the advent of the mobile Internet era, smart mobile terminal devices have gradually become necessary communication and entertainment tools for people to live, work and travel. Moreover, with the rapid development of connecting OTG (On-The-Go) technology, data processing equipment for realizing the OTG mode between intelligent mobile terminals has also emerged at the historic moment, but the current equipment can be connected to a single intelligent mobile terminal. , and cannot support the data transmission between the smart mobile terminal and the personal computer PC at the same time, and the existing portable devices only support the universal serial bus USB or only support the connection of the card reader interface. In order to meet different needs, people, It is usually ne...
