Description

Text wireless transmitter and system based on USB

Technical Field

The invention relates to the technical field of computers, in particular to a text wireless transmitter and a text wireless transmitter system based on a USB.

Background

With the development of technology, each user has more and more smart devices, for example, most people generally have more of a smart phone, a notebook computer, a tablet computer and a desktop computer. The intelligent devices can be used as a medium for storing information, and can store some important file materials of the user, and the like, besides providing convenience for the user in learning, working and living. This inevitably involves migration of files between different smart devices. The current file migration mainly comprises the following steps: 1. storage medium (e.g., USB flash drive) based migration; 2. migrating through the data line; 3. migrating the network disk; 4. hua is the "one touch transfer" migration and so on. These file migration methods have the following problems:

1. the method is characterized in that the method comprises the following steps that a USB device is used for conducting work such as mutual transmission of texts and files, the files need to be stored on the USB device, the risk that the USB device carries viruses and malicious codes exists, and hidden dangers of file leakage and out of control exist.

2. Although the automatic playing function of the U disk of the Windows operating system can enable the U disk to automatically play files or programs in the U disk at the moment of plugging the U disk into a computer, the automatic file migration operation can be realized. However, the automatic playing function started by the operating system is dangerous and is easily utilized by viruses, an experienced system installer often disables the automatic playing function after the system is installed, and some safety software automatically disables the automatic playing function. The user also needs to use this function, but the user experiences insufficient experience to cause virus intrusion, "introduce a room", and this subjective will cause the system poisoning experience to be very unfriendly to the user, making it unwarranted for the user to use.

3. The method for automatically opening the USB device on the computer only achieves the purpose of automatically opening the resource manager of the USB device, and does not automatically execute programs.

4. In the method for automatically operating software on a computer by using a USB device, a program or an executable file is stored in a storage device of the USB device, a user needs to import the program or the executable file into the storage device of the USB device, sometimes, the program is difficult to automatically operate due to insufficient authority given by an operating system, and codes of the program are fixed, so that the user sometimes needs to modify in real time but is inconvenient to import and export the file.

5. The file can be transmitted and migrated between different devices by the existing network application program (such as a hundred-degree network disk, a WeChat transmission assistant and the like). But the chat tools such as a hundred-degree network disk, WeChat and QQ are more in steps and are more complicated. If a user needs to transmit a file of the mobile phone end to the computer end, the user needs to log in an account of the mobile phone application first, then transmit the file, then log in an account of the computer end application, and finally search and download the file, so that the user experience is not friendly. A plurality of users are required to operate the mouse and the keyboard, and the whole migration process is not transparent, automatic and maintenance-free. In addition, account numbers, passwords, links, extraction codes and the like are in software and digital forms, and parts of the account numbers, the passwords, the links, the extraction codes and the like are exposed or easy to crack, so that potential safety hazards of data leakage and data stealing exist. And the risks of wrong sending, missed sending and the like caused by misoperation exist. When a program such as WeChat transmits a shared text, various texts such as various icons and expressions which are included in Chinese and English cannot be well processed, and the problems of information loss, messy codes and the like can occur.

6. The Huache 'one touch transmission' technology realizes a maintenance-free migration process without user input, but has certain sealing property and limitation in the application process. The technology needs the notebook and the mobile phone equipment to be supported by an NFC (near field communication) module, the cost price is high, and many devices in the market are not available, so that the popularization is not high. When the user uses the technology, the user needs a Huawei notebook computer and also needs a Huawei mobile phone which meets the support of a collision transmission technology, and the technology has higher application threshold, poor interoperability and limited application range.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and 2, a first embodiment of the invention provides a USB-based text wireless transmitter 100, which includes: the USB plug comprises a USB plug 10, a shell, and a main control chip 21, a memory and a wireless communication module 30 which are positioned in the shell, wherein one end of the USB plug 10 is connected to the shell and is electrically connected with the main control chip 21, the wireless communication module 30 and the memory are electrically connected with the main control chip 21, and the main control chip 21 is configured to implement the following steps by executing a computer program stored in the memory:

s101, original encoded data of a text transmitted by the currently connected information transmitting apparatus is received through the wireless communication module 30.

In this embodiment, the main control chip 21 may be a single chip or a microprocessor, and the text wireless transmitter 100 is an embedded system based on a dedicated/general microprocessor or a single chip processor, and can execute a computer program to complete functions such as automatic execution of control scheduling, encoding and decoding, and data communication.

In this embodiment, the wireless communication module 30 may be a bluetooth module, a WiFi module, or an IR module, and the invention is not limited in particular.

In this embodiment, the information sending device may be, for example, a smart phone, a smart tablet, or a PDA, in which a text to be transmitted is stored, and the information sending device also has a wireless communication function, so as to send original encoded data of the text to the text wireless transmitter 100 based on the wireless communication function.

S102, the received original coding data is subjected to coding conversion to obtain a conversion coding character string uniquely corresponding to the original coding data.

And S103, inputting the conversion code character string to a target computer to which the USB plug is currently connected in a keyboard inputting mode.

And S104, controlling the target computer to automatically call a preset decoding program, and reversely restoring the converted coding character string into original coding data and storing the original coding data.

In this embodiment, the text may be a chinese character, an english character, a number, a punctuation mark, or the like, and the text may be injected into the target computer by a direct keyboard entry method. However, injection into the target computer through a USB interface typically only supports ASCII encoded characters. Different processing is required for different types of text.

(1) And for English characters, encoding modes such as ASCII encoding, UTF-8 and the like can be directly adopted, and the English characters are directly input into the target computer through a keyboard input mode and a USB interface.

(2) For Chinese characters, the Chinese characters cannot be directly input in a character input mode through a keyboard. Because the characters can not be directly input into a target computer through a USB interface in a character input mode, the characters can not be directly input automatically. If the ASCII code characters such as English characters, numeric characters and the like are input/input and then Chinese is input by a Chinese input method, the problem of repeated codes of Chinese input codes exists, so that manual selection and repeated removal are needed, and automatic conversion and Chinese input cannot be realized.

Therefore, the embodiment converts various non-ASCII coded original coded data (generally binary data, such as UTF-8 coded data, GBK coded data, GB2312 coded data, Unicode coded data and ANSI coded data) stored in a mobile phone and a computer, including Chinese codes, into a symbolic code by coding (such as converting into a symbol represented in a 16-system or 10-system form, a BCD code or a compressed BCD code), converts the symbolic code into a conversion coded character string uniquely corresponding to the symbolic code, so that the symbolic code can be input into a target computer in a keyboard sequence form through a USB HID, controls the target computer to automatically call a preset decoding program, reduces the conversion coded character string into the original coded data, stores the original coded data in a computer memory or a file, and realizes various non-ASCII coded binary data including Chinese codes, and inputting the characters into a target computer through a USB HID.

Specifically, for the chinese character, taking the UTF-8 encoding mode as an example, the UTF-8 encoding generally uses 3 bytes to represent a chinese character, and the highest bit of each byte is 1 (i.e. the encoding is a value exceeding 0X80 in hexadecimal or more than 128 in decimal according to an unsigned integer), and these bytes are all beyond the ASCII encoding representation range, so that the bytes cannot be directly entered as a keyboard character entry mode through the USB interface.

For this purpose, the present embodiment converts each non-ASCII encoded byte (including ASCII encoded bytes) into a symbolized code in decimal representation, then expresses the ASCII encoded number corresponding to the numeric bit of the symbolized code in decimal representation in character form, and then outputs each numeric bit in a character string composed of an ASCII encoded number character sequence. Because the UTF-8 coded Chinese characters adopt 3 bytes to represent one Chinese character, the highest bit of each byte is 1, the corresponding decimal value is a value above 128, the Chinese character needs to be represented by 3 digital characters, which is called a decimal digit conversion coded character string, and the string length is 3. A hexadecimal numerical representation form corresponding to the UTF-8 coded data can also be adopted to form corresponding characters, 2 hexadecimal bits (0-9 and A-F characters represent digital bits) are required to represent an 8-bit byte, and the method is called a hexadecimal digital conversion coding character string.

Taking decimal character strings as an example, a chinese character needs 3 decimal digit conversion coding character strings (each length is 3), that is, 9 decimal digit characters are needed to represent the character, for the convenience of processing, the conversion coding character string formed by every 3 digits represents a UTF-8 coded byte, and the character strings are separated by separators (such as;, "%," # ", and other non-numeric ASCII coding characters) to form a serial connection conversion coding character string.

For example, if a Chinese character "good" word is to be transmitted, taking UTF-8 encoding as an example, UTF-8 encoding generally uses 3 bytes to represent the words in hexadecimal numbers as: 0xE5, 0xA5, x0BD, the corresponding decimal values (decimal digit conversion code string) are expressed as: "229", "165", "189". The 3 decimal digit ASCII code character strings are connected in a 'connection mode' by using separators to form '229, 165 and 189' serial conversion coding character strings.

In addition, the original coded data can also be directly coded according to the symbol expressed in the hexadecimal numerical form to form a conversion coded character string. For example, the Chinese character "good" is represented by UTF-8, and the UTF-8 encoding generally uses 3 bytes and hexadecimal numerical values as follows: 0xE5, 0xA5, x0BD, in the form of hexadecimal numeric representation corresponding to UTF-8 encoded data, form a corresponding character, and require 2 hexadecimal bits (represented by 0-9 and A-F characters) to represent each byte, e.g., 0xE5 represents a hexadecimal digit conversion encoded string: "E5", connecting the strings by separators "to form a serial conversion code string composed of hexadecimal digital ASCII code strings: "E5, a5, BD".

It should be noted that in other embodiments of the present invention, other methods of Chinese transcoding may be used to convert the original encoded data into various character strings containing ASCII characters. For example, in Windows Powershell script language, the [ Web. HttpUtility ]: UrlEncode and UrlDecode functions, or C # HttpUtility. UrlEncode and HttpUtility. UrlDecode methods can also be used to convert the Chinese binary byte array into the encoded URL character string and to transcode it reversely, so as to realize the lossless and reliable HTTP transmission from the Web server to the client and the input of Chinese information between the mobile phone and the PC through the USB HID channel. Similar or same kind of encoding and decoding methods are adopted, and all belong to the protection scope of the invention.

In this embodiment, all the concatenated conversion code strings include ASCII code characters, and the characters can be directly injected through a keyboard, and the input into the target computer can be completed by the text wireless transmitter.

In this embodiment, after the text wireless transmitter 100 is inserted into the target computer, the converted concatenated and converted code string may be entered into the target computer by a keyboard entry method.

Specifically, first, text wireless transmitter 100 may automatically send keyboard commands to the target computer, such as: the Windows window key + R key is called out to run a program interface, then a command of 'not copied: \ in.txt' is automatically input, a text file is automatically created in a target computer, the whole serial connection conversion coding character string is automatically input into the target computer, and the text file is closed (through automatically inputting 'atl key + F4 key'), saved (whether the closed prompt is saved or not is confirmed through automatically inputting 'Y', or directly saved through 'atl key + F key + S key').

Then, after the text file (e.g. d: \ in.txt) containing the concatenated conversion code string is stored in the target computer, the conversion is required to be recovered to the UTF-8 coded Chinese character string, and the process needs a special decoding program to be completed, and the decoding program needs to be stored in the target computer in advance, and the storage path is configured to the text wireless transmitter 100, so that the dynamic calling of the text wireless transmitter 100 is facilitated. After the decoding program is called, the target computer automatically finishes reading the text file containing the serial connection conversion coding character string: d, completing decoding and recovering to original coded data, such as UTF-8 coded data, and generating a corresponding output file, or automatically opening and copying Chinese characters in the output file into a pasting board for sharing by a computer to other application programs.

Specifically, the decoding program reads the serial conversion code character string, decomposes the serial conversion code character string into conversion code character strings (including 3 decimal ASCII code character strings spaced by separators), respectively restores and converts the decimal ASCII code character strings spaced by separators into 3 16-system numerical values, and then writes the 3 hexadecimal numerical values into an output file d: \ out.txt in a hexadecimal (binary stream) form to correspondingly form UTF-8 coded data of one chinese character. Thus, the process of symbolizing and coding the Chinese character sent from the mobile phone, inputting the Chinese character into a target computer and decoding and restoring the Chinese character into the Chinese character by the text wireless transmitter 100 is realized.

For example, in one specific example:

taking the example of transmitting a chinese character "good" word, the text wireless transmitter 100 will generate in.txt at the target computer and form a conversion code string storing "229, 165, 189", the text wireless transmitter 100 will automatically call a decoding program to read in.txt and obtain the conversion code string "229, 165, 189", then obtain 3 decimal ASCII code strings "229", "165", "189", respectively, and recover the conversion to 3 16-ary numeric values, respectively: 0xE5, 0xA5 and x0BD, then writing 3 hexadecimal values into an output file d \.

Finally, the text wireless transmitter 100 automatically turns off the dedicated decoding program (by automatically inputting "atl key + F4 key"), and the text wireless transmitter 100 automatically sends keyboard commands to the target computer, such as: the method comprises the steps of calling a running program interface by a Windows window key + R key, then automatically inputting a ' not'd: \ in.txt ' command, opening an output file generated by a decoding program by a text editor, such as d: \.

For example, in one possible exemplary application scenario: the user needs to import the text in the mobile phone, such as chat records, address books, memorandum, document copying and text paragraphs, etc., into the computer or other machine for display, modification, editing, processing, storage, etc. Especially under the conditions of no network or poor network coverage signals (such as remote mountainous areas, tunnels, airplanes and the like), the sharing and migration of network programs through WeChat and the like cannot be finished. Even under the condition of a network, by the APP mode, a user needs to pre-install a plurality of software, establish or input an account number and a password, log in, scan a code, authenticate, verify and the like, the operation is complex, and risks of network diffusion, mistaken distribution, leakage and the like exist.

When the embodiment is used for text migration, a user only needs to insert the text wireless transmitter 100 into a target computer, the user sends the text wireless transmitter 100 through a mobile phone Bluetooth communication program APP (such as various types of Bluetooth assistants, Bluetooth serial port debugging APPs and other general free software, or specially developed Bluetooth point-to-point transceiving APPs) and injects, guides and transmits the text to the target computer through a USB keyboard input mode, and the text is transparently transmitted to the computer for the user to use without other manual intervention operations.

In addition, by using the embodiment to perform text migration, a plurality of users can conveniently send texts to a target computer through terminals such as mobile phones and the like, and the texts are used for application scenes such as joint modification, editing, cooperative office work and the like.
