The embodiment of the application provides a data transmission method, a data transmission device, a terminal and a storage medium. The following are detailed below.
Referring to fig. 1, fig. 1 is a schematic view of a scenario of a data transmission method according to an embodiment of the present application.
In fig. 1, a first terminal and a second terminal are directly connected through WiFi for data transmission, where the first terminal may send files such as audio, video, and photos to the second terminal, and the second terminal may send feedback data including its own memory capacity information to the first terminal while receiving the files.
It should be noted that, during the transmission process of the first terminal and the second terminal, the dual-transmission may transmit data to the other side or receive data transmitted by the other side. The first terminal and the second terminal can obtain the memory capacity information of the opposite side through the feedback data sent by the opposite side, so that data transmission failure caused by insufficient memory capacity of the opposite side is prevented, and the efficiency of WiFi direct connection data transmission is improved.
In the embodiment of the present application, a data transmission method is described in detail by taking an example in which a first terminal receives feedback data sent by a second terminal.
Referring to fig. 2, fig. 2 is a first flowchart of a data transmission method according to an embodiment of the present disclosure.
In step S110, feedback data transmitted by the second terminal a plurality of times is received.
In the data transmission process, the first terminal may receive feedback data sent by the second terminal, where the feedback data sent by the second terminal includes memory capacity information of the second terminal, and the second terminal may send the feedback data to the first terminal at regular time, for example, once every two seconds.
Optionally, the second terminal may also send the feedback data according to the data transmission progress, the second terminal serves as a receiving terminal, the first terminal serves as a sending terminal, and the second terminal sends the feedback data according to the data transmission progress in the data transmission process, for example, when the transmission progress reaches 50%, the second terminal starts to send the feedback data to the first terminal for multiple times.
In the data transmission process, the first terminal may be a receiving terminal or a transmitting terminal. The second terminal may be a receiving terminal or a transmitting terminal. The examples given in this embodiment should not be construed as limiting the invention.
In step S120, the plurality of feedback data are analyzed to obtain a plurality of memory capacity information of the second terminal.
After the first terminal receives the plurality of feedback data sent by the second terminal, the plurality of data are analyzed to obtain a plurality of memory information of the second terminal. The feedback data includes the memory capacity information of the second terminal sent by the second terminal to the first terminal, and the feedback data may also include file information such as audio, video, and pictures sent by the second terminal to the first terminal.
The memory capacity information of the second terminal obtained by the first terminal analyzing the multiple feedback data may be the memory capacity information of the second terminal at different times, for example, the memory information of the first feedback data received at point 10 and point 50, the memory information of the second feedback data received at point 10 and point 52, and the memory information of the feedback data received at other times, and so on.
Preferably, the memory capacity information of the second terminal obtained by the first terminal analyzing the multiple feedback data may be the memory capacity information of the second terminal every fixed time period, for example, every two seconds, the second terminal sends the feedback data to the first terminal, and the first terminal analyzes the feedback data to obtain the memory capacity information of the second terminal every fixed time interval.
In step S130, it is determined whether the plurality of memory capacity information of the second terminal satisfy a preset condition.
After the plurality of memory capacity information of the second terminal is acquired, the memory capacity information needs to be judged, so that the fact that the remaining memory capacity of the second terminal is sufficient is determined, and data transmission between the first terminal and the second terminal is guaranteed to be completed. And if the plurality of memory capacity information of the second terminal is judged not to meet the preset condition, continuously receiving the feedback data of the second terminal, repeating the steps, and if the memory capacity information of the second terminal is judged to meet the preset condition, entering the step S140.
Optionally, it may be determined whether the memory capacity information of the second terminal is greater than a preset value, and if the memory capacity information is greater than the preset value, it indicates that the remaining memory capacity of the second terminal is sufficient, so as to meet the data transmission requirement.
The first terminal can also judge whether the memory capacity information of the second terminal meets the preset condition or not according to the memory capacity information of the second terminal and the current data transmission speed. For example, the data transmission speed is 1MB/S, the current remaining memory capacity of the second terminal is 1G, how long the second terminal can still perform data transmission is calculated according to the transmission speed 1MB/S and the current remaining memory capacity 1G of the second terminal, and if the data transmitted by the first terminal is just enough to store the data in the remaining memory capacity of the second terminal, the remaining transmission time is already calculated, and if the data to be transmitted is added into the first terminal, the data to be transmitted is transmitted at the speed of 1MB/S, and extra time is consumed. If the sum of the originally predicted data transmission time and the added time is greater than the time calculated by the data transmission speed and the remaining memory capacity of the second terminal, it is indicated that the normal completion of the data transmission of the first terminal and the second terminal cannot be guaranteed.
Preferably, in this embodiment of the application, the preset condition may be calculated by setting a first threshold and a second threshold and acquiring memory capacity information received three times in succession. The memory capacity information received three times in succession may be first memory capacity information, second memory capacity information, and third memory capacity information in order, by determining whether the first memory capacity information, the second memory capacity information, and the third memory capacity information are smaller than a first threshold. If so, judging whether the difference between the first memory capacity information and the second memory capacity information and the difference between the second memory capacity information and the third memory capacity information are smaller than a second threshold value, and if so, indicating that the residual memory capacity is insufficient in the data transmission process of the second terminal, so that the smooth completion of the data transmission cannot be ensured.
In step S140, data transmission is interrupted and prompt information is generated.
Under the condition that the plurality of memory capacity information of the second terminal are judged not to meet the preset conditions, data transmission between the first terminal and the second terminal is interrupted at the moment, and data transmission failure caused by insufficient memory capacity of the second terminal is prevented.
At this time, a prompt message can be generated to prompt the suspension of data transmission, so as to prevent data transmission failure. The prompt message may be generated by the first terminal, may be displayed in the first terminal, or may be sent to the second terminal through the first terminal to prompt a user of the second terminal.
To sum up, in the process that the first terminal transmits data to the second terminal, the first terminal receives feedback data sent by the second terminal for many times, analyzes the multiple feedback data to obtain multiple pieces of memory capacity information of the second terminal, and determines whether the multiple pieces of memory capacity information of the second terminal meet preset conditions, if so, the data transmission is interrupted and prompt information is generated. In the data transmission process of the first terminal and the second terminal, the residual memory capacity information of the second terminal is obtained through feedback data sent by the second terminal for multiple times, when the memory capacity information of the second terminal meets preset conditions, the first terminal can interrupt data transmission in time and send prompt information, data retransmission caused by accidental interruption of memory problems in the transmission process is avoided, and the transmission efficiency of WIFI direct connection is improved.
Referring to fig. 3, fig. 3 is a second flow chart of a data transmission method according to an embodiment of the present application.
In step S201, feedback data transmitted by the second terminal a plurality of times is received. This step is the same as step S110, and is not described herein again.

After the plurality of feedback data are analyzed, a plurality of memory capacity information of the second terminal are obtained, and the memory capacity information received three times in succession is obtained, which may be first memory capacity information, second memory capacity information, and third memory capacity information, where the first memory capacity information, the second memory capacity information, and the third memory capacity information are the second terminal memory capacity information obtained in sequence.
It should be noted that, the first terminal analyzes the multiple feedback data of the second terminal, where the feedback data sent by the second terminal may be continuously sent within a fixed time interval or may be continuously sent at irregular time, and therefore, the obtained first memory capacity information, second memory capacity information, and third memory capacity information may be the same or different in the obtaining time interval.
In step S205, it is determined whether the first memory capacity information, the second memory capacity information, and the third memory capacity information are lower than a first threshold.
A first threshold may be set, and if the first memory capacity information, the second memory capacity information, and the third memory capacity information of the second terminal are all smaller than the first threshold, it indicates that the remaining memory capacity of the second terminal is insufficient and cannot meet the requirement for completing data transmission, and then the process proceeds to step S206 for further processing.
If the first memory capacity information, the second memory capacity information and the third memory capacity information are not less than the first threshold, it indicates that the remaining memory capacity of the second terminal is sufficient, and data transmission can be continued, and at this time, feedback data of the second terminal is continuously received, so that the memory shortage caused by the second terminal performing other tasks is prevented.
In step S206, it is determined whether the difference between the first memory capacity information and the second memory capacity information, and the difference between the second memory capacity information and the third memory capacity information are smaller than a second threshold.
A second threshold may be set, and when the difference between the first memory capacity information and the second memory capacity information and the difference between the second memory capacity information and the third memory capacity information are smaller than the second threshold, it indicates that the remaining memory capacity of the second terminal is insufficient, and the requirement for completing data transmission cannot be met.
If the difference between the first memory capacity information and the second memory capacity information and the difference between the second memory capacity information and the third memory capacity information are not less than the second threshold, it indicates that the remaining memory capacity of the second terminal is sufficient, and data transmission can be continued.
In step S207, the data transmission of the first terminal and the second terminal is interrupted and the prompt message is generated at the first terminal.
The first terminal obtains a plurality of memory capacity information of the second terminal from a plurality of feedback data sent by the second terminal, and judges that the remaining memory capacity of the second terminal is insufficient according to the plurality of memory capacity information.
At this time, the first terminal generates a prompt message to prompt the user that the memory capacity of the second terminal is insufficient and the transmission needs to be stopped, and the first terminal can also send the prompt message to the second terminal, so that the user of the second terminal can see the prompt message.
To sum up, in the embodiment of the present application, the first terminal obtains the identification data by receiving the feedback data sent by the second terminal for multiple times, and analyzes the feedback data, obtains the memory capacity information of the second terminal from the identification data, and then obtains three consecutive times of memory capacity information, that is, one memory capacity information, the second memory capacity information, and the third memory capacity information, from the multiple memory capacity information. And then judging whether the first memory capacity information, the second memory capacity information and the third memory capacity information are lower than a first threshold value, if so, judging whether the difference between the first memory capacity information and the second memory capacity information and the difference between the second memory capacity information and the third memory capacity information are smaller than a second threshold value, if so, interrupting the data transmission of the first terminal and the second terminal and generating prompt information at the first terminal.
In this embodiment, through obtaining the memory capacity information of the second terminal many times, prevent that the second terminal from when the memory capacity is not enough, avoid in the transmission process because the unexpected interrupt of the problem of memory not enough leads to data retransmission, improved WIFI lug connection's data transmission efficiency.
