Description
Technical field
The present invention relates to a kind of method of computer transmission file, relate in particular to the method for a kind of many computers without Internet Transmission file.
Background technology
In present office space, transfer files is all to transmit by network conventionally, or copy by USB flash disk, but use Internet Transmission file to cause possibly data to leak, and copy also more loaded down with trivial details by USB flash disk, especially, in the situation that file is revised repeatedly, use USB flash disk copy to come and go to plug back and forth pretty troublesome.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of many computers of internet and LAN (Local Area Network) that do not need without the method for Internet Transmission file, has avoided the unsafe factor of Internet Transmission, does not also need to plug back and forth USB flash disk simultaneously.
To this, the invention provides the method for a kind of many computers without Internet Transmission file, comprise transmitting-receiving processor and two computers at least, and comprise the following steps:
By transmitting-receiving processor with computer expert crosses USB mouth and USB plug links together, described transmitting-receiving processor comprises MCU, described MCU is used for realizing the two-way communication control between transmitting-receiving processor and computer, and by USB mouth and USB plug display file Transfer Window on the computer monitor being connected;
In transmitting-receiving processor, to a unique identity code of each computer coupling, this identity code is corresponding and associated one by one with title and the file storing path of computer;
By USB mouth and USB plug by the title real-time synchronization of each computer to file Transfer Window;
And, in the time that wherein one or more computer is dragged to file as transmitting terminal on file Transfer Window, MCU detects after paper delivery signal, and Transmit message receives prompting message to the specified receiving end of transmitting terminal, and file is sent to the corresponding file storing path of receiving end;
Wherein, between described transmitting-receiving processor and computer, carry out data transmission by the data line being connected with USB plug with USB mouth.
Two or at least the USB mouth of two computers plug the transmitting-receiving processor of mutual transmission file and data, this transmitting-receiving processor is the MCU with one or more USB plug, after a certain computer is opened, directly file is placed into the position of transmission, while being dragged on file Transfer Window by file software, MCU can detect data, and transmitting-receiving processor is carried out file transfer on the computer to the receiving end of specifying, and receiving end can be alerted and received file, select to preserve address/path; On the contrary, another computer also can use the same method Transmit message to a certain computer.
Compared with prior art, transmitting-receiving processor of the present invention and computer expert cross USB mouth and USB plug links together, and transmitting-receiving processor comprises the MCU for controlling the two-way communication between transmitting-receiving processor and computer, that is to say, between multiple computers, be to carry out the transmission of data and file by transmitting-receiving processor, communicating by letter between computer and transmitting-receiving processor is that the data line by being connected in USB mouth and USB plug is realized, so, in the situation that there is no internet and LAN (Local Area Network), the present invention also can realize the file transfer between many computers fast, both avoided the unsafe factor of Internet Transmission, that also can avoid using USB flash disk to copy is loaded down with trivial details.
Further improvement of the present invention is, described computer expert crosses USB mouth and USB plug is connected on same transmitting-receiving processor, described transmitting-receiving processor is by least two USB mouths of USB plug branch output, and described USB plug is connected to one to one on computer by USB mouth respectively.Preferably include 2 or 3 computers, described transmitting-receiving processor is by the USB plug branch output USB mouth identical with computer quantity.
