Detailed ways

The present invention will be further elaborated below in conjunction with the accompanying drawings.

The realization steps of the present invention are as follows:

(1) Communication between the smartphone and the remote computer and the near-end computer. The mobile phone and the remote computer access and communicate through GPRS, while the mobile phone and the near-end computer communicate and control through Bluetooth access. Finally, the file transfer between the two computers is based on the ordinary network transmission of the TCP protocol.

(2) Obtain the file directory information of the remote computer and display it on the mobile phone screen.

(3) Design the server software on the remote computer. The server needs to communicate and interact with the mobile phone, authenticate the connection request sent by the mobile phone user; obtain the local file directory information and send it to the mobile phone, and connect with the target computer for file transfer.

(4) Design the software on the near-end computer. The near-end computer needs to communicate with the mobile phone wirelessly, send its own information to the mobile phone, and let the mobile phone select the target machine; the near-end computer also needs to receive the files sent by the remote computer.

The basic structure of the present invention is shown in Figure 1, and the function of the present invention mainly has the participation of three modules, that is, a smart phone, a remote computer, and a local computer. They each need to complete different tasks to coordinate and complete the function of file transfer. The work that the smart phone needs to complete is to communicate with the remote computer, send the account password to the remote computer to verify its legitimacy, and receive the file directory information sent by the remote computer; operate on the mobile phone and select the file to be transferred ; Communicate with the near-end computer through Bluetooth to obtain the identification of each near-end computer, and select one of them as the target computer; finally, the IP address of the target computer and the selected file information need to be sent back to the remote computer. The work that the remote computer needs to complete is the communication with the smart phone. First, it receives the account number sent by the mobile phone to verify whether it is a legitimate user. If it is a legitimate user, it starts to start the program of the functional module for obtaining the file directory, and sends the directory information to to the phone. If it is not a legitimate user, this part of the program will not be started; then receive the file information and the IP address information of the target machine sent back by the legitimate user of the mobile phone; the communication with the local computer is mainly to transfer the selected file to local computer. The work that the near-end computer needs to complete is to communicate with the smart phone and send some identification information of itself to the mobile phone; after being selected as the target computer by the mobile phone, it communicates with the remote computer to receive the transmitted files.

It can also be seen from Figure 1 that the file transfer technology based on remote control includes three important parts: TCP, Bluetooth and GPRS. The smart phone accesses the remote computer through GPRS, and the smart phone sends the account password to the remote computer to verify its legitimacy. After passing the verification, the file directory of the remote computer is obtained and displayed on the mobile phone screen. Then select the file to be transferred on the mobile phone, and then communicate with the near-end computer via Bluetooth to obtain the identification (computer name, IP address, etc.) The address and selected file information is sent back to the remote computer.

The remote computer accepts the account number and password sent by the mobile phone, and verifies whether it is a legitimate user. If it is a legal user, it starts to start the program for obtaining the functional module of the file directory, and sends the directory information to the mobile phone. If it is not a legal user, this part of the program will not be started, and then the file information and the IP address information of the target machine will be received by the mobile phone legal user to send back the file information it chooses to transmit.

The specific flowchart of this method is shown in Figure 2. When the smart phone has selected the file to be transferred and the target machine for transferring the file, after clicking Confirm, the mobile phone sends the information of the file to be transferred and the IP address of the near-end target machine to remote computer. After receiving the information, the remote computer establishes a connection with the near-end target machine through TCP, and transfers the file to the near-end computer. Realized the transfer of files.
