Apparatus and method for off line data exchange

Abstract

The invention discloses a device and method for off-line data exchange. The device includes a main controller module and a memory module for exchanging data with it, a function module for exchanging data with the main controller module, a USB HOST module, and a power management module , a user interaction module, an intelligent interface module; the method includes: inserting a required device with a USB function for data exchange into a USB port, powering on for initialization; the main controller finds new hardware through level detection, and prompts the user Whether to install the driver program, after the user selects the data to be exchanged, the main controller moves the data into the memory for caching; then transfers the file data to the USB data interface of the corresponding device. The invention realizes data exchange between various devices based on the USB interface, or performs data exchange and simple data processing functions with devices of other types of interfaces.

Description

technical field [0001] The invention relates to intelligent data exchange technology, in particular to a device and method capable of off-line data exchange based on data protocol exchange, and belongs to the field of data processing and exchange. Background technique [0002] At present, with the continuous improvement of people's life, electronic technology has been promoted unprecedentedly. Various consumer electronics products are emerging in an endless stream. In addition to powerful computers, mobile storage products such as flash drives, MP3, etc.; office equipment such as printers, projectors, etc.; home equipment such as TV, audio, set-top boxes, etc. . With the increasingly wide application and popularization of these products, people's life and office are more convenient. [0003] The above-mentioned consumer electronics products are widely classified, and each complies with its own technical standards and data interfaces. It has dedicated functions but is diffi...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned consumer electronics products are widely classified, and each complies with its own technical standards and data interfaces. It has dedicated functions but is difficult to share. In order to unify management and maximize resource sharing, people expect centralized management through the Internet to achieve resource sharing. At present, there are several interconnection methods, namely wired interconnection, wireless interconnection and offline interconnection. The offline interconnection mode represented by the USB bus interface is gradually developing and growing. However, due to the large technical gap between the USB master and slave devices, and the At present, the USB protocol is based on the computer operating system, and the USB main control design is basically used on the computer, which causes the exchange of devices based on mobile storage, especially devices such as USB flash drives, which are separated from the computer (that is, offline) There are obvious deficiencies in data exchange under the circumstances, which are specifically reflected in: (1) without the computer, the data in the USB flash drive cannot or is difficult to print directly through the printer; (2) without the computer, the PPT files in the USB flash drive Also can't directly show by projector at present; (3) break away from computer, between USB flash drive, between MP3 and USB flash drive, the data exchange between MP3 also is difficult to carry out; (4) break away from computer, whether can USB flash drive, the audio files in MP3 can be directly played on the home audio system, and whether the picture files in the USB flash drive can be directly browsed on the TV is also a question that everyone is very concerned about;

[0004] If there is a technology that can effectively solve the above problems, it will undoubtedly bring greater convenience to users and promote the continuous popularization and development of mobile storage products. At present, no relevant documents that can effectively solve the above technical problems have been retrieved.
