Abstract

The utility model relates to a data transmitter of a USB interface. With the development of era, the information resources are more and more rich and people rely more and more on small-sized data storage equipment such as a U disk and the like. The existing products such as the U disk, an MP3, an MP4 and the like only can transmit files through being connected with a computer, but can not directly and conveniently transmit data from one party to another party. The data transmitter comprises a reader shell (1) and a writer shell (2) with shells (14), wherein the reader shell is connected with the writer shell; a reader shell body is internally provided with a reading single chip microcomputer (3) of model 89C516; the reading single chip microcomputer of model 89C516 is connected with a U disk module (4) and a reading switch (5); a writer shell body is internally provided with a writing single chip microcomputer (6) of model 89C516; the writing single chip microcomputer of model 89C516 is connected with a U disk module (7) and a writing switch (8); and the reading single chip microcomputer of model 89C516 is connected with the writing single chip microcomputer of model 89C516 through a lead (11). The data transmitter is used for data transmission.

Description

The USB interface data link

Technical field:

The utility model relates to a kind of data transmission device, is specifically related to a kind of USB interface data link.

Background technology:

Along with the development of current era, information resources are more and more abundanter, and people also more and more rely on small-sized data storage devices such as USB flash disk.But products such as existing USB flash disk, MP3, MP4 can only pass through to connect the computer transfer files, and can not direct convenience data be reached the opposing party from a side.

Summary of the invention:

The purpose of this utility model provides the data transmission device between a kind of small memory device, utilizes the USB interface of single-chip microcomputer to transmit, and realizes function of reading.

Above-mentioned purpose realizes by following technical scheme:

The USB interface data link, its composition comprises: have reading casing and writing casing of casing, the described casing of reading connects and to write casing, be equipped with in the described housing of reading casing and read single-chip microcomputer model 89C516, the described single-chip microcomputer model 89C516 that reads connects and to read the USB flash disk module and to read switch, be equipped with in the described housing of writing casing and write single-chip microcomputer model 89C516, the described single-chip microcomputer model 89C516 that writes connects and to write USB flash disk module and write switch, and the described single-chip microcomputer model 89C516 that reads connects by lead and writes single-chip microcomputer model 89C516.

The described USB flash disk module of reading comprises chip model CH375 and reads USB interface that the described USB flash disk module of writing comprises chip model CH375 and writes USB interface.

Beneficial effect:

1. the trouble that needs operating computer when the utility model has reduced transmission reaches the purpose more easily of sharing that makes resource, realizes simplifying the quick interchange of work and study information in the daily life.

The utility model success will thoroughly break away from the constraint of computer to data transmission, promptly simplified operating process.

3. its economic worth of the utility model and market outlook will be very huge; This product will improve the level and the level of information fast greatly, and its social value is difficult to estimate.

4. wire communication of the present utility model is not subjected to the weather and the influence of topography, has guaranteed the system communication reliability.

5. the data that overcome when transmitting USB flash disk in the people life of the utility model must rely on this shortcoming of computer.This product does not rely under the situation of computer, can realize that the data between USB flash disk and the USB flash disk transmit by single-chip microcomputer and its corresponding data interface module.
