It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
An execution main body of the data transmission method may be the data transmission device provided in the embodiment of the present application, or an electronic device integrated with the data transmission device, where the data transmission device may be implemented in a hardware or software manner. The electronic device may be a personal computer PC, a notebook computer, a server, or the like.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a data transmission method according to an embodiment of the present disclosure. The specific process of the data transmission method provided by the embodiment of the application can be as follows:
101. and carrying out data transmission with the mobile terminal through socket connection, wherein the socket connection is established between the electronic equipment and the mobile terminal.
The embodiment of the present application takes an electronic device as an example for explanation. The scheme of the embodiment of the application can be applied to backup of data on the mobile terminal to the PC terminal, and can also be applied to scenes that data transmission between two devices is needed such as recovery of data stored on the PC terminal to the mobile terminal.
When the data on the mobile terminal is backed up to the PC end, the mobile terminal is a data sending end, and the PC end is a data receiving end. When the data stored on the PC end is restored to the mobile terminal, the PC end is a data sending end, and the mobile terminal is a data receiving end.
In the embodiment of the application, the electronic device is connected with the mobile terminal through a Universal Serial Bus (USB) data line, so that the mobile terminal is connected with the electronic device through a socket interface of an Android Debug Bridge (ADB), and after the socket connection is established, a communication protocol supported by the ADB interface is used between the electronic device and the mobile terminal to perform signaling interaction and data transmission.
The Protocol for performing communication between the electronic device and the mobile terminal may be an existing communication Protocol, such as a TCP/IP (transmission Control Protocol, transmission Control Protocol/Internet Protocol, Internet Protocol), or may be a Protocol in a certain format agreed between the electronic device and the mobile terminal, as long as the Protocol is a communication Protocol that can be supported by an ADB interface.
The electronic equipment calls an ADB forward instruction through an ADB interface, and Socket connection between the electronic equipment and the mobile terminal is established. And the electronic equipment sends or receives signaling and data through a socket port specified in the adb forward command. For example, the adb forward instruction is an adb forward tcp:2320tcp 1220;
the port 2320 is used as a Socket port of the electronic device, and the electronic device sends an instruction or transmits data to the mobile terminal through the port and/or receives the instruction or data sent by the mobile terminal through the port; the port 1220 is used as a Socket port of the mobile terminal, through which the mobile terminal listens for commands or data from the electronic device and/or sends commands or data to the electronic device, and for the Socket connection, the mobile terminal is equivalent to a server and the electronic device is equivalent to a client.
In the data transmission process, the data sending end determines data to be sent, wherein the data to be transmitted can be selected manually by a user, or the data sending end obtains data matched with the data type from the data sending end or from a specified path of the data sending end according to the data type set by the user and takes the data as the data to be transmitted.
In some embodiments, the method may further comprise: and when receiving data or an instruction sent by the mobile terminal, sending a receiving receipt to the mobile terminal, wherein if the mobile terminal does not receive the receiving receipt after sending the data or the instruction, the socket connection is judged to be disconnected.
After the data sending end sends data or some specific instructions to the data receiving end, if the data receiving end receives the data or the instructions, a receipt is sent to the data sending end immediately. And if the data sending end does not receive the receipt sent by the data receiving end for a long time, judging that the socket connection between the electronic equipment and the mobile terminal is disconnected.
It can be understood that, when the mobile terminal is a data receiving terminal, if the electronic device does not receive a receipt sent by the data receiving terminal for a long time, it is determined that the socket connection between the electronic device and the mobile terminal has been disconnected. When the electronic equipment is a data receiving end, if the mobile terminal does not receive a receiving receipt sent by the data receiving end for a long time, a prompt message is sent to the electronic equipment through the ADB interface to inform that the socket connection of the electronic equipment is disconnected, and when the electronic equipment receives the prompt message, the socket connection between the electronic equipment and the mobile terminal can be determined to be disconnected.
102. And recording the transmission progress of the data transmission when the socket connection disconnection is detected.
And when the electronic equipment detects that the socket is disconnected, recording the transmission progress of the current data transmission. When the data sending end sends data, a number is created for each file, all files to be sent are sorted according to the numbers, a field mark is added to each file, and the field mark is used for indicating whether the file is transmitted to the data receiving end or not. For example, if the file has been transmitted to the data receiving end, the value of the field identifier is modified to 1, and the value of the field identifier of the file that has not been transmitted in the file list is still 0.
When the socket connection is disconnected, both the data sending end and the data receiving end can record the current data transmission progress. The transmission progress information recorded by the data sending end includes a file sending state list, and the file sending state list can be determined according to the field identification in the file list. The transmission progress information recorded by the data receiving end comprises file information of the last received file and the received length of the file, and the file information of the last received file is the information of the file being received when the socket connection is disconnected.
103. And controlling a socket connection port of the electronic equipment to be switched to a first standby port from a first preset port, wherein the socket connection port of the mobile terminal is switched to a second standby port from a second preset port.
104. And recovering the socket connection between the electronic equipment and the mobile terminal based on the first standby port and the second standby port.
When the socket connection disconnection is detected, the electronic equipment can also switch the communication port. In general, a socket connection is disconnected, which may be caused by network abnormality or port occupation. The network anomaly is not a generalized network anomaly, and after the electronic equipment and the mobile terminal establish a communication protocol based on an ADB interface, a small local area network is established, and the network anomaly refers to the fact that the local area network is abnormal. In addition, since other processes running in the electronic device may use the port, especially when some processes with higher priority occupy the port, the port used by the socket connection is occupied. All of the above causes the socket connection to be disconnected.
At this time, in order to ensure the continuous transmission of data, socket port switching is performed. In the data transmission process, the port initially used by the electronic device is a first preset port, and the port initially used by the mobile terminal is a second preset port. In addition, a first standby port is preset for the electronic equipment, and a second standby port is preset for the mobile terminal.
And controlling a socket connection port of the electronic equipment to be switched to a first standby port from a first preset port, wherein the socket connection port of the mobile terminal is switched to a second standby port from a second preset port.
And after the switching of the first standby port and the second standby port is completed, reconnection of socket connection is realized based on the switched ports.
105. And continuing to transmit data between the electronic equipment and the mobile terminal based on the recovered socket connection and the transmission progress.
After the socket connection is recovered, the data transmission progress is saved when the connection is disconnected, so that the data transmission can be continued according to the recorded transmission progress after reconnection.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the data transmission method provided in the embodiment of the present application, data transmission between the electronic device and the mobile terminal is performed through socket connection, and when it is detected that the socket connection is disconnected, a transmission progress of the data transmission is recorded; the socket connection port of the electronic equipment is controlled to be switched from a first preset port to a first standby port, wherein the socket connection port of the mobile terminal is switched from a second preset port to a second standby port; recovering socket connection between the electronic equipment and the mobile terminal based on the first standby port and the second standby port; the data transmission between the electronic equipment and the mobile terminal is continued based on the restored socket connection and transmission progress, through the scheme, when the socket connection disconnection between the electronic equipment and the mobile terminal is detected, the switching of the transmission ports is carried out to realize reconnection quickly, and the data transmission progress is saved when the connection is disconnected, so that the data transmission can be continued according to the recorded transmission progress after reconnection to improve the data transmission efficiency.
In some embodiments, to improve the utilization rate of the port, before the socket connection port controlling the electronic device is switched from the first preset port to the first standby port, the method may further include: when the socket connection disconnection is detected, sending a first connection instruction to the mobile terminal based on the first preset port so as to reconnect with the mobile terminal; and if the reconnection fails, executing control to switch the socket connection port of the electronic equipment from a first preset port to a first standby port.
Because socket connection and disconnection can be caused by various reasons, when socket connection and disconnection are detected, reconnection based on the current port can be tried, if reconnection fails, switching of the port is carried out again, so that the utilization rate of the port is improved, and the situation that the port of other processes is occupied and the operation of other processes is influenced while data transmission is guaranteed is avoided.
In some embodiments, continuing data transmission between the electronic device and the mobile terminal based on the restored socket connection and the transmission progress includes: when the data transmission is data backup, determining the last received file information according to the transmission progress, and sending the last received file information to the mobile terminal, wherein the mobile terminal continues to backup the data to the electronic equipment based on the last received file information; and when the data transmission is data recovery, determining the file information received last according to the transmission progress, and continuously sending the data to the mobile terminal according to the file information received last.
The data recovery transmission process is different for different data transmission scenes.
When data backup is carried out, the electronic equipment is a data receiving end, and the transmission progress information recorded by the electronic equipment comprises file information of a last received file and the received length of the file. The mobile terminal is a data sending end, and the mobile terminal records a file sending state list. Therefore, after the socket connection is restored, the electronic device determines the last received file information according to the transmission progress, and sends the last received file information to the mobile terminal, so that the mobile terminal can continuously back up the data to the electronic device based on the last received file information.
On the contrary, when data recovery is performed, the electronic device is a data sending end, and the electronic device records a file sending state list. The mobile terminal is a data receiving terminal, and the transmission progress information recorded by the mobile terminal comprises file information of the last received file and the received length of the file. Therefore, after the socket connection is recovered, the electronic device can directly determine the file information received last according to the transmission progress, and continuously send the data to the mobile terminal according to the file information received last.
It should be noted that, in other embodiments, the data sender may record both the file sending status list and the file information of the last received file, as well as the received length of the file.
The method according to the preceding embodiment is illustrated in further detail below by way of example.
Referring to fig. 2, fig. 2 is a second flow chart of a data transmission method according to an embodiment of the invention. The method comprises the following steps:
201. and carrying out data transmission with the mobile terminal through socket connection, wherein the socket connection is established between the electronic equipment and the mobile terminal.
The scheme of the embodiment of the application can be applied to backup of data on the mobile terminal to the PC terminal, and can also be applied to scenes that data transmission between two devices is needed such as recovery of data stored on the PC terminal to the mobile terminal. When the data on the mobile terminal is backed up to the PC end, the mobile terminal is a data sending end, and the PC end is a data receiving end. When the data stored on the PC end is restored to the mobile terminal, the PC end is a data sending end, and the mobile terminal is a data receiving end.
The electronic equipment is connected with the mobile terminal through the USB data line, so that the mobile terminal is connected with the electronic equipment through a socket established between the mobile terminal and the electronic equipment through an ADB interface, and after the socket connection is established, signaling interaction and data transmission are carried out between the electronic equipment and the mobile terminal through a communication protocol supported by the ADB interface.
202. And recording the transmission progress of the data transmission when the socket connection disconnection is detected.
When the socket connection disconnection is detected, both the data sending end and the data receiving end can record the current data transmission progress. The transmission progress information recorded by the data sending end includes a file sending state list, and the file sending state list can be determined according to the field identification in the file list. The transmission progress information recorded by the data receiving end comprises file information of the last received file and the received length of the file, and the file information of the last received file is the information of the file being received when the socket connection is disconnected.
203. And sending a first connection instruction to the mobile terminal based on the first preset port so as to reconnect with the mobile terminal.
If the reconnect fails, 204 is performed.
If the reconnect is successful, 207 is performed.
204. And judging whether the reconnection times are greater than the preset times.
In order to improve the utilization rate of the port, when it is detected that socket connection is disconnected, reconnection based on the current port may be attempted first, where the reconnection number may be multiple times, for example, an upper limit value of the reconnection number is set as a preset number, time of each reconnection is a first preset duration, that is, if reconnection does not succeed within the first preset duration after a first connection instruction is sent to the mobile terminal based on the first preset port, it is determined that reconnection fails this time. Otherwise, the reconnection is determined to be successful, and the specific first preset time and the preset times can be set according to needs, for example, the first preset time is 5-15s, and the preset times is 3-8.
And if the reconnection times are not more than the preset times, returning to execute 203.
If the number of reconnects is greater than the predetermined number, 205 is performed.
205. And controlling a socket connection port of the electronic equipment to be switched to a first standby port from a first preset port, wherein the socket connection port of the mobile terminal is switched to a second standby port from a second preset port.
If the reconnection fails after multiple reconnection attempts, the ports are switched, and the specific switching manner refers to the above embodiments and is not described herein again.
It can be understood that, if the socket connection is to be successfully established, it is assumed that the electronic device and the mobile terminal are still connected through the USB data line, and therefore, after the socket connection disconnection is detected, it is first detected whether the mobile terminal is still connected to the electronic device, which may be detected through the ADB connection state. If yes, switching the ports.
In addition, since the electronic device is the party that actively initiates the socket connection, the mobile terminal is the party that waits for the connection. Therefore, after waiting for the second preset duration, if the reconnection is still not successful, the mobile terminal switches the port from the second preset port to the second standby port. And the second preset time length is equal to the product of the first preset time length and the preset times.
206. And recovering the socket connection between the electronic equipment and the mobile terminal based on the first standby port and the second standby port.
In some embodiments, restoring the socket connection between the electronic device and the mobile terminal based on the first backup port and the second backup port may include: determining a first standby port of the electronic equipment and a second standby port of the mobile terminal; generating a second connection instruction according to the first standby port and the second standby port; and sending the second connection instruction to the mobile terminal so as to recover the socket connection between the electronic equipment and the mobile terminal based on the first standby port and the second standby port.
After the ports are switched, a connection instruction is regenerated based on the switched ports, and the connection instruction is sent to the mobile terminal by the electronic equipment so as to reestablish socket connection.
207. And continuing to transmit data between the electronic equipment and the mobile terminal based on the recovered socket connection and the transmission progress.
In some embodiments, after the socket connection between the electronic device and the mobile terminal is restored based on the first standby port and the second standby port, the method may further include: if the socket connection is successfully restored, executing data transmission between the electronic equipment and the mobile terminal based on the restored socket connection and the transmission progress; and if the socket connection recovery fails, determining a new first standby port from the plurality of preset ports of the electronic equipment again, and returning to execute control to switch the socket connection port of the electronic equipment from the first preset port to the first standby port.
In this embodiment, a plurality of standby ports may be preset, for example, two standby ports are respectively set for the electronic device and the mobile terminal, if the switched first standby port still cannot be successfully connected, the switched first standby port is switched to the second standby port to try reconnection, and reconnection is abandoned until all the standby ports cannot be successfully reconnected, so as to prompt the user to disconnect the connection.
As can be seen from the above, in the data transmission method provided in the embodiment of the present invention, when it is detected that the socket connection between the electronic device and the mobile terminal is disconnected, the data transmission method attempts to establish a connection with the mobile terminal again based on the current port. When reconnection fails, the transfer ports are switched to realize reconnection quickly, and the data transfer progress is saved when the connection is disconnected, so that data transfer can be continued according to the recorded data transfer progress after reconnection, and the data transfer efficiency is improved.
