In the data interaction process of the intelligent interaction panel and the wireless screen transmitter, the wireless screen transmitter sends heartbeat data packets to the intelligent interaction panel at preset intervals to indicate the connection state of the intelligent interaction panel.

The first embodiment is as follows:
fig. 1 is a flowchart of a method for dynamically setting a screen transmission timeout period according to an embodiment of the present invention.
The dynamic setting method of the screen transmission timeout time provided by the embodiment can be executed by a wireless screen transmitter.
As shown in fig. 2, the device for transmitting a screen required in the present embodiment includes at least one transmitting end 100, a receiving end 200 corresponding to each transmitting end, and a wireless screen transmitter 300. The transmitting end 100 includes but is not limited to: mobile phones, notebook computers, tablet computers, speakers, and the like; the receiving end 200 includes but is not limited to: a tablet computer, a flat television, an intelligent interactive tablet and the like; the wireless screen transmitter 300 is provided with a motion sensor inside, and the motion sensor includes but is not limited to: a gyroscope sensor, an acceleration sensor, and a rotation vector sensor.
In an embodiment, the wireless screen transmitter 300 may be connected to the sending end through a USB interface, and the wireless screen transmitter 300 and the receiving end 200 perform data transmission through a wireless communication method, for example, a communication method such as WiFi or ZigBee may be used, and in particular, a communication method of WiFi is used.
Optionally, the transmitting end 100 and the receiving end 200 are installed with screen transmission application software, and the screen transmission application software may be installed in the transmitting end 100 and the receiving end 200 in advance, or may be downloaded from a third-party device or a server and installed for use when the transmitting end 100 and the receiving end 200 start a screen transmission application.
In one implementation, the third-party device is the wireless screen transmitter 300, when the wireless screen transmitter 300 is connected to the transmitting terminal 100, screen-casting application software is stored in the wireless screen transmitter 300, and is transmitted to the transmitting terminal 100 after being connected to the transmitting terminal 300, and the transmitting terminal 100 installs the screen-casting application software. After the screen projection application software is installed, the sending end 100 may intercept a currently displayed picture, transmit the picture to the wireless screen transmitter 300, and wirelessly transmit the picture to the receiving end 200 by the wireless screen transmitter 300 for displaying.
In this embodiment, one receiving end 200 may simultaneously receive and display the pictures transmitted by the multiple transmitting ends 100 through the wireless screen transmitter 300, for example, simultaneously display the pictures transmitted by the multiple transmitting ends 100 in a split screen manner.
Specifically, referring to fig. 1, the method for dynamically setting the screen transmission timeout time provided in this embodiment specifically includes:
s101, detecting the motion state variation of the wireless screen transmission device through a built-in motion sensor.
And S102, when the motion state variation reaches a certain amplitude, triggering a receiving end which is currently connected with the wireless screen transmitter to reduce the timeout time of disconnection.
In this embodiment, when the user pulls out the wireless screen transmitter from the transmitting end, the motion state of the wireless screen transmitter is changed greatly in a short time, for example, a large amplitude shake, a large height change, a large speed change, or the like occurs, therefore, when the variation of the motion state of the wireless screen transmitter reaches a certain amplitude within a preset time through the motion sensor built in the wireless screen transmitter, the wireless screen transmitter may send a first trigger instruction to the receiving end, trigger the receiving end to reduce the timeout time of the disconnection, therefore, if the user really pulls out the wireless screen transmitter, the receiving end can actively quit the connection state with the wireless screen transmitter more quickly, and removing the last transmitted picture in time and jumping back to the corresponding interface so as to facilitate the subsequent operation of the user.
Specifically, in one implementation, the motion sensor is a gyroscope sensor, and the motion state variation is an angular deflection value.
If a user wants to pull the wireless screen transmitter from a sending end, a certain change of the angle of the wireless screen transmitter can be caused, the gyroscope sensor can detect the deflection value of the angle and send the deflection value to a processor of the wireless screen transmitter, and when the processor judges that any one of the deflection values of the angle within a preset time (such as 100ms) is larger than a certain amplitude value, the processor sends a first trigger instruction to the receiving end to trigger the receiving end to reduce the timeout time of connection disconnection.
For example, assuming that the timeout time for disconnection set by the receiving end by default is 15 seconds, after receiving the first trigger instruction, the timeout time for disconnection may be set from 15 seconds to 10 seconds.
In another implementation manner, the motion sensor is an acceleration sensor, and the motion state variation is an acceleration value.
Similarly, if a user wants to pull the wireless screen transmitter from the transmitting end, the wireless screen transmitter may be displaced to some extent, so as to generate an acceleration value. The acceleration sensor can detect the acceleration value and send the acceleration value to the processor of the wireless screen transmitter, and the processor sends a first trigger instruction to the receiving end when judging that the acceleration value is larger than a certain amplitude value, and triggers the receiving end to reduce the timeout time of disconnection.
It should be noted that, in other embodiments of the present invention, the operation sensor may also be a gravity sensor, a rotation vector sensor, a direction sensor, etc., as long as it can detect the change of various motion states that may be generated when the wireless screen transmitter is pulled out, and these solutions are within the protection scope of the present invention.
In addition, it should be noted that, in general, it takes about 200ms from the judgment to the sending of the first trigger instruction by the processor of the wireless screen transmitter, which is much shorter than the time from the picking up of the wireless screen transmitter to the pulling out of the wireless screen transmitter by the user, so that the problem that the user has pulled out the wireless screen transmitter and the first trigger instruction has not been sent does not occur generally.
In summary, according to the dynamic setting method for the screen transmission timeout time provided by this embodiment, the motion state of the wireless screen transmitter is detected to obtain whether the user has an intention to pull out the wireless screen transmitter, and when it is determined that the user has the intention to pull out the wireless screen transmitter, a first trigger instruction is sent to the receiving end, so that the receiving end reduces the timeout time for disconnection, and thus the receiving end can relatively quickly exit from a currently displayed picture in a scene where the user pulls out the wireless screen transmitter. Furthermore, on the basis, the default timeout time can be set to be longer, and the disconnection of the user can be ensured not to occur under the condition of short-time communication interruption due to network fluctuation in the normal continuous use process.
On the basis of the first embodiment, in a preferred embodiment of the present invention, after step S102, the method further includes:
and when the connection with the sending end is still kept after the preset time, triggering the receiving end to prolong or recover the overtime time of disconnection.
In this embodiment, it is considered that the motion state of the wireless screen transmitter is not necessarily generated by pulling out the wireless screen transmitter by a user, and in some cases, for example, the motion state of the wireless screen transmitter may be changed due to the fact that the user moves a sending end connected to the wireless screen transmitter or a table on which the sending end is located vibrates, so that the wireless screen transmitter sends a first trigger instruction to a receiving end. In this case, since the timeout period of the receiving end is shortened, it is easy to cause a problem that the user is disconnected from the wireless screen transmitter when short-time communication is interrupted due to network fluctuation during normal continuous use.
Therefore, in this embodiment, after the wireless screen transmitter sends the first trigger instruction and after a predetermined time elapses, if it is still detected that the wireless screen transmitter is connected to the sending end, it indicates that the user has no intention to actively pull out the wireless screen transmitter, and the change in the motion state of the wireless screen transmitter is caused by other factors, at this time, the wireless screen transmitter sends the second trigger instruction to the receiving end, so that the receiving end extends or recovers the timeout time of disconnection, and it is ensured that the user does not disconnect the connection in the case of short-time communication interruption due to network fluctuation during normal continuous use.
For example, if the timeout time set by the receiving end is 15 seconds by default, and is shortened to 10 seconds after receiving the first trigger command, the timeout time is restored to 15 seconds after receiving the second trigger command. Of course, the receiving end may also set the ultrasonic time to other times after receiving the second trigger instruction, for example, 20 seconds, 12 seconds or other values, which is not limited in the present invention.
In addition, it should be noted that, in this embodiment, if the receiving end automatically disconnects from the wireless screen transmitter after reaching the timeout time, the timeout time is reset, for example, 10 seconds is reset to 15 seconds, and when the connection is established again next time, the initial disconnection ultrasonic time is still set to 15 seconds.
Example two:
fig. 3 is a flowchart of a second screen transmission timeout time dynamic setting method according to an embodiment of the present invention.
The method for dynamically setting the touch-up timeout time provided by this embodiment may be executed by a receiving end, and in particular, executed by one or more processors in the receiving end, and includes:
s201, receiving a first trigger instruction transmitted by a wireless screen transmitter; the first trigger instruction is generated by the wireless screen transmitter when the variation of the motion state of the wireless screen transmitter reaches a certain amplitude.
And S202, reducing the timeout time of disconnection according to the first trigger instruction.
For example, assuming that the timeout time set by the receiving end is 15 seconds by default, the timeout time is shortened to 10 seconds after receiving the first trigger command.
In this embodiment, the receiving end can actively reduce the timeout time of the disconnection after receiving the first trigger instruction of the wireless screen transmitter, so that the receiving end can quickly exit from the currently displayed picture in a scene where the user pulls out the wireless screen transmitter.
On the basis of the second embodiment, after step S202, the method further includes:
and when the heartbeat data packet from the wireless screen transmitter is received before the timeout time is reached, the timeout time of disconnection is recovered to a default initial value.
In this embodiment, if the receiving end still can receive the heartbeat data packet from the wireless screen transmitter before the timeout time is reached, it indicates that the wireless screen transmitter is still in a working state, that is, still in a connection state with the transmitting end, at this time, it indicates that generation of the first trigger instruction may not be caused by the user actively pulling out the wireless screen transmitter, that is, the user does not have an intention to pull out the wireless screen transmitter, and the receiving end restores the timeout time of disconnection to a default initial value, so as to ensure that the user does not disconnect in the case of short-time communication interruption due to network fluctuation during normal continuous use.
For example, when the receiving end sets the timeout time to 10 seconds, if the receiving end receives the heartbeat packet from the wireless screen transmitter in the 5 th second, the receiving end restores the timeout time of the disconnection to 15 seconds.
On the basis of the second embodiment, after step S202, the method further includes:
receiving a second trigger instruction transmitted by the wireless screen transmitter; the second trigger instruction is generated when the wireless screen transmitter judges that the second trigger instruction is still connected with the sending end after the preset time for sending the first trigger instruction;
and according to the second trigger instruction, prolonging or recovering the connection disconnection timeout.
When the wireless screen transmitter sends a first trigger instruction and after a preset time, if the wireless screen transmitter still detects that the wireless screen transmitter is connected with a sending end, the wireless screen transmitter does not have the intention of actively pulling out the wireless screen transmitter by a user, the change of the motion state of the wireless screen transmitter is caused by other factors, at the moment, the wireless screen transmitter sends a second trigger instruction to the receiving end, so that the receiving end prolongs or recovers the overtime time of disconnection, and the disconnection of the user can be ensured not to occur under the condition of short-time communication interruption due to network fluctuation in the normal continuous use process.
For example, if the timeout time set by the receiving end is 15 seconds by default, and is shortened to 10 seconds after receiving the first trigger command, the timeout time is restored to 15 seconds after receiving the second trigger command. Of course, the receiving end may also set the ultrasonic time to other times after receiving the second trigger instruction, for example, 20 seconds, 12 seconds or other values, which is not limited in the present invention.

Furthermore, on the basis, the default timeout time can be set to be longer, and the disconnection of the user can be ensured not to occur under the condition of short-time communication interruption due to network fluctuation in the normal continuous use process.
