Data transmission method, system and device based on USB equipment and medium

Abstract

The invention discloses a data transmission method, system and device based on USB equipment, and a medium. The method comprises the steps: receiving transmission data transmitted by terminal equipment in a point-to-point communication mode; performing code conversion on the transmission data to obtain coded data; generating decoding information according to the coded data; and sending the decodedinformation to the computer terminal in a USB HID mode, so that the computer terminal decodes the decoded information to obtain transmission data. Installation of drivers and application programs isnot needed, a user does not need to touch human-computer interaction equipment such as a target computer keyboard and a mouse in the whole text transmission and sharing operation scheduling process, user operation steps and execution condition limitation are reduced, virus and bacterium cross infection caused by contact with the surfaces of various kinds of equipment is reduced. USB equipment doesnot need to provide a file storage function, cannot spread viruses, cannot be limited by forbidden USB storage equipment, is efficient, safe and large in application scene, and can be widely appliedto the technical field of data transmission.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a text transmission method, system, device and medium based on a USB device. Background technique [0002] A USB device is a piece of hardware at the end of a USB cable that performs user functions. USB devices can be divided into three parts: USB bus interface, USB logical device and functional device. U disk is the abbreviation of USB (universal serial bus) disk, which is a typical USB device. U disk is a kind of flash memory, so it is sometimes called flash disk. The biggest difference between U disk and hard disk is that it does not need a physical drive, plug and play, and its storage capacity far exceeds that of a floppy disk, making it extremely portable. U disk integrates disk storage technology, flash memory technology and universal serial bus technology. The USB port is connected to the computer, which is the channel for data input / output; the main control...

Problems solved by technology

However, it is dangerous for the operating system to enable the automatic playback function, and it is easy to be exploited by viruses. Experienced system installers often disable this function after installing the system, and some security software will automatically disable this function

[0012] The method of automatically opening the USB device on the computer is only to automatically open the resource manager of the USB device, and does not automatically execute the program.

[0013] In the method for a USB device to automatically run software on a computer, the described program or executable file is stored in the storage device of the USB device, and the user needs to import the program or executable file into the storage device of the USB device, sometimes due to The permissions given by the operating system are not enough to run automatically, and the code of the program is fixed. Sometimes it is inconvenient for users to make real-time modifications, and they need to import and export files.
