As shown in fig. 1, the technical solution of the embodiment of the present invention specifically includes the following steps:
s110, acquiring at least two heartbeat reply times, and calculating a heartbeat reply time average value.
And the heartbeat reply time is the time required by the screen projection sending end from the sending of the heartbeat packet to the receiving of the data packet matched with the heartbeat packet.
In this embodiment, the execution main body is a screen-casting sending end, where the screen-casting sending end is to send the multimedia file to a screen-casting receiving end, so as to synchronize the screen content to a terminal device of the screen-casting receiving end, and the screen-casting sending end may be, for example, a mobile phone, a tablet, or another terminal device. The multimedia file can be a file corresponding to contents such as video, audio or pictures. The screen projection receiving end is a terminal device that acquires the multimedia file and plays the content corresponding to the multimedia file on a screen, and may be, for example, a television, a projector, or other terminal devices.
The heartbeat packet is a data packet in a preset format and is used for regularly informing the self state of the other side between the screen projection sending end and the screen projection receiving end, and the screen projection sending end regularly sends the heartbeat packet to the screen projection receiving end and receives the data packet matched with the heartbeat packet and replied by the screen projection receiving end.
Specifically, the screen projection sending end and the screen projection receiving end are connected to the same wireless network, or the screen projection receiving end is connected to a wired network, the screen projection sending end is connected to the wireless network, and the wired network and the wireless network are connected to the same wireless router. At the moment, the screen-casting sending end sends heartbeat packets to the wireless router at fixed time, the wireless router forwards the heartbeat packets to the screen-casting receiving end, the screen-casting receiving end generates data packets matched with the heartbeat packets after receiving the heartbeat packets, the data packets are sent to the wireless router, and the wireless router forwards the data packets to the screen-casting sending end.
In the embodiment of the invention, the screen projection sending end needs to acquire the time for sending the heartbeat packet and the time for receiving the data packet matched with the heartbeat packet. Specifically, the current time may be recorded when the heartbeat packet is sent and the data packet matched with the heartbeat packet is received. The time stamps in the heartbeat packet and the time stamps in the data packets matched with the heartbeat packet may also be obtained respectively, and the present embodiment does not limit the manner of obtaining the time for sending the heartbeat packet and the time for receiving the data packets matched with the heartbeat packet.

And S120, acquiring the file downloading speed sent by the screen projection receiving end.
The file downloading speed is the downloading speed of the multimedia file received by the screen projection receiving end.
Before the screen projection is carried out by the screen projection receiving end, the multimedia file is downloaded, and the file downloading speed can be calculated according to the file size and the downloading time of the multimedia file. The file downloading speed can be used as a judgment basis for the network connection state.

S230, acquiring sending time of sending a target heartbeat packet to the screen projection receiving end and receiving time of receiving a target data packet which is sent by the screen projection receiving end and matched with the target heartbeat packet.
Specifically, the screen-casting sending end can record the current time as the sending time and the receiving time when sending the target heartbeat packet and receiving the target data packet matched with the target heartbeat packet. The time stamps in the target heartbeat packet and the target heartbeat data packet matched with the target heartbeat packet may also be acquired as the sending time and the receiving time, respectively.
S240, taking the difference value between the receiving time and the sending time as target heartbeat reply time.

And S270, acquiring the file downloading speed sent by the screen projection receiving end.
And S280, determining the level of the network connection state according to the average value of the heartbeat reply time and the file downloading speed.
Specifically, an average value interval in which the heartbeat reply time average value is located and a speed interval in which the file download speed is located may be determined, and the level of the network connection state may be determined according to the average value interval and the speed interval. For example, the higher the level of the network connection state, the more stable the network connection state is.
Accordingly, S280 may further include:
s281, determining an average value interval where the heartbeat reply time average value is located and a speed interval where the file downloading speed is located.
In the embodiment of the invention, the average value interval and the speed interval can be divided in advance, and different levels are corresponding to different average value intervals and different speed intervals. For example, the average value of the heartbeat reply time may be divided into four intervals of 50ms to 100ms, 100ms to 300ms, 300ms to 1s, and more than 1s, the file download speed may be divided into four intervals of more than 20M/s, 5M/s to 20M/s, 1M/s to 5M/s, and less than 1M/s, the levels corresponding to different average value intervals and different speed intervals may be determined according to the following table one, and the higher the level, the more stable the network connection state is indicated.
Watch 1
And S282, taking the target level corresponding to the average value interval and the speed interval as the level of the current network connection state.
After the average value interval of the heartbeat reply time average value and the speed interval of the file downloading speed are determined, the level of the corresponding network connection state can be determined according to the two intervals.
And S290, judging whether the level corresponding to the network connection state is less than or equal to a preset level, if so, executing S2100, otherwise, executing S2110.
When the level of the network connection state is less than or equal to the preset level, it is indicated that the stability of the network connection state is poor at this time, and a prompt needs to be given to the user to improve the user experience.
And S2100, prompting the user to match with the network connection state.
Specifically, the levels of different network connection states may be set to correspond to different prompts. For example, the user may be prompted to wait patiently when the level of the network connection status is small, to view the network settings when the level of the network connection status is minimum, and so on.
And S2110, ending.
