Description

Double-sided USB-to-serial port with storage function

Technical Field

The utility model relates to a USB changes serial ports TTL technical field, concretely relates to changes serial ports from taking two-sided USB of storage.

Background

When the converter of the USB-to-serial port is used on a computer for the first time, the converter needs to be installed by the driving of a main chip, and after the converter is installed successfully, the converter is recognized by a PC (personal computer) so as to establish a virtual COM port. However, the driving program is stored in the optical disc or hard disc, so that the searching or carrying is inconvenient. The product ensures that the driving and the converter are straight, the trouble of carrying an optical disk or searching a hard disk is saved, and a storage element is arranged in the converter for storing software such as driving and the like. Moreover, the USB connector can be inserted randomly without dividing into a positive plug and a negative plug. Based on this, the utility model designs a from taking two-sided USB of storage to change the serial ports to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a from taking two-sided USB of storage to change the serial ports to solve the problem that proposes in the above-mentioned background art.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: from taking two-sided USB of storage to change serial ports, including casing 1 and outside main USB interface, the inside of casing 1 is equipped with USB and changes serial ports and storage PCBA, and USB changes the inside configuration Flash storage unit of serial ports, and USB changes the serial ports and is equipped with USB and changes the serial ports converter, and the bottom of casing 1 is fixed to be pegged graft and is had the two-sided arbitrary plug 2 of USB.

Wherein, the external main USB interface is divided into two equal independent USB interfaces, and the USB interface is HUB.

And the two groups of USB interfaces are respectively and electrically connected with the Flash storage unit and the USB-to-serial port converter.

And the USB interface transmits serial data through the USB-to-serial converter.

The Flash storage unit can read and write in the transmission process of the USB to the serial port, does not interfere with the data transmission of the serial port and can independently perform the data transmission.

One specific application of this embodiment is: a Flash storage unit is arranged in the USB-to-serial port, so that the contents such as trend and the like can be conveniently stored. In order to avoid interference and occupy the transmission of the USB interface to the serial port, an external USB main interface is firstly divided into 2 equal independent USB interfaces which are HUBs, the two independent USB interfaces are respectively connected with a Flash storage unit, and the other USB interface is used for a USB to serial port converter to carry out serial port TTL communication.

The Flash storage unit can read and write in the transmission process of the USB to the serial port, does not interfere with the transmission of the serial port and can independently perform the transmission at the same time.

First, the external USB interface is divided into two independent USB interfaces by the USB HUB with dual output ports. Then, two USB interfaces operate independently, one is used in Flash memory device to make memory unit, which is convenient for user to store and move corresponding content, even can be used as U disk. And the other path of the data is not influenced to carry out information conversion and transmission and is used for a converter for converting the USB into the serial TTL.

In addition, for the convenience of use, the USB connector is designed into a mode of randomly inserting the front side and the back side, and the front side and the back side of the USB connector are not required to be distinguished to be randomly inserted into a host when in use.

The USB-to-serial port is always stored in the converter, and data conversion and storage are not affected when the USB-to-serial port is used. For convenient use, the USB connector can be inserted into the host randomly without dividing the front and the back.
