Text wireless transmitter and system based on usb

Abstract

The invention discloses a USB-based text wireless transmitter and system. The transmitter includes: a USB plug, a casing, a main control chip, a memory, and a wireless communication module. One end of the USB plug is connected to the casing, and Electrically connected to the main control chip, the main control chip is configured to implement the following steps by executing the computer program stored in the memory: receiving the original encoded data of the text sent by the currently connected information sending device through the wireless communication module; Converting the received original coded data through code conversion to obtain a uniquely corresponding conversion code string; inputting the conversion code string into the target computer currently connected to the USB plug by means of keyboard input; controlling The target computer automatically invokes a preset decoding program to restore the converted encoded string to original encoded data. The invention can safely and quickly realize the migration of files between different devices.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a USB-based text wireless transmitter and system. Background technique [0002] With the development of technology, each user has more and more smart devices. For example, for most people, they generally have a plurality of smart phones, notebook computers, tablets and desktop computers. In addition to providing users with convenience in study, work and life, these smart devices can also be used as information storage media to save some important documents of users. This inevitably involves the migration of files between different smart devices. The current file migration is mainly through the following methods: 1. Migration based on storage media (such as U disk); 2. Migration through data lines; 3. Network disk migration; 4. Huawei "one touch transfer" migration, etc. These file migration methods have the following problems: [0003] 1. For work such as text and file trans...

AI Technical Summary

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

Users also need to use this function, but due to their lack of experience, they lead to virus invasion, "leading wolves into the house". This kind of non-subjective experience that leads to system poisoning is very unfriendly to users, making users want to use it but dare not use it.

[0005] 3. 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

[0006] 4. In the method for the 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 it is difficult to run automatically because the permissions given by the operating system are not enough, 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.

Several user mouse and keyboard operations are required, and the entire migration process is not transparent, automatic, and maintenance-free

In addition, account numbers, passwords, links, extraction codes, etc. are all software and digital forms, and some of them are exposed or easily cracked, which poses a security risk of data leakage and theft

And there are risks such as wrong delivery, wrong delivery, and missed delivery caused by misoperation

When WeChat and other programs transmit shared text, they cannot handle various icons and emoticons mixed in Chinese and English well, and problems such as missing information and garbled characters will occur

[0008] 6. Huawei's "one-touch transmission" technology realizes the maintenance-free migration process without user input, but the application process has certain closures and limitations

This technology requires notebooks and mobile devices to have NFC (Near Field Communication) module support, which is expensive and not available in many devices on the market, so its popularity is not high

To use this technology, users need a Huawei laptop and a Huawei mobile phone that meets the technical support of one-touch transmission. The application threshold is high, the interoperability is not good, and the scope of application is limited.
