| With the progress of science and technology,and the rapid development of Internet technology,the communication between people has been changed greatly by mobile phones and computers.In many cases,people's daily work need to complete by file transfer.Commonly,the most way was use mobile storage devices or transfer based on Internet network to transfer file.But the transfer way of the larger pictures,video files,which simply rely on the mobile storage devices or data flow,will lead to the waste of the cost of capital,cyber source virus,a lot of trouble to the user and so on.Therefore,file sharing transfer will be difficult to carry out.In view of the above problems,this article designed a software which named“High speed transfer”,which can be realized in the Android and Windows system equipments.By the portable hotspot in Android system,the people operate the WIFI hardware module of Android system,and establishing a local area network WIFI,and Internet network transfer can replace the file.On the basis of LAN WIFI,Socket communication is realized technically,and the file flow is low cost and fast transfer.“High speed transmission” is without the help of any external hardware,the application can completely break away from the Intertnet,and complete the sharing and transfer of the files at a low cost and rapidly.In the process of network setup,the software implements one click operation,greatly reducing user's operation capability,and making up for the defect of file transfer without Internet.In this paper,the key technologies and related knowledge used in the system are described in detail.The result of the test of the running system shows that the software is stable and can achieve the smooth transfer of multiple files at the same time,and can realize breakpoint file transfer and other functions,and has a certain commercial value and the strong promotional practical value. |
