Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The terminal networking method provided by the embodiment of the application can be applied to any terminal in various terminal command systems. For example: the application scene of the vehicle command system can be as follows: the plurality of vehicles are configured as task vehicles for executing tasks, the plurality of task vehicles form a vehicle command system, and networking relations are required to be established among the vehicles in the process of executing the tasks in an outgoing mode so as to complete various command tasks. For another example: the application scenario of the user terminal command system may be: the user terminals (such as mobile phones and computers) are respectively used by different users, and form a user terminal command system, and the users complete various command tasks through the corresponding user terminals, so that networking relations among the user terminals are also required to be established. For another example: the terminal command system is a hybrid terminal command system, which comprises different types of terminals (such as vehicles and mobile phones), and networking relations can be established among the different types of terminals so as to execute more complex command tasks.
For example, referring to fig. 1, a schematic diagram of a vehicle command system provided in an embodiment of the present application is shown, where the vehicle command system includes communication command vehicles a-F, and the networking method described in the embodiment of the present application may be applied to any one of the communication command vehicles a-F. It should be noted that, before the group gateway system is not established, communication can be performed between the communication command vehicles, and more stable and more convenient intercommunication can be realized by establishing the networking relationship.
Regardless of the form of the terminal, in order to ensure that the terminal can complete the corresponding command task, the functions of the terminal may include: video/audio decoding and encoding functions, video/audio acquisition functions, video/audio playing (displaying) functions, and the like. The video and audio decoding and encoding can be realized by a video and audio comprehensive module, and the processes of video receiving, encoding, decoding, transmitting and the like can be completed, and the receiving interface can be as follows: HDMI (High Definition Multimedia Interface )/VGA (Video Graphics Array, video graphics array)/SDI (serial digital interface, digital component serial) and the like, the video formats that can be encoded and decoded can be: H264/H265/MPEG2 (Moving Picture Experts Group ), etc. Video and audio acquisition, including video acquisition and sound acquisition, the video acquisition can be realized through the camera, and sound acquisition can be realized through sound acquisition module (such as microphone). Playing (displaying) the video and audio may be accomplished by a display. How these functions are implemented in particular will be described in connection with embodiments of the method.
In addition, in the embodiment of the present application, the communication manner between the terminals may be satellite communication, and the influence of external factors (such as distance) on the satellite communication is small. In order to realize satellite communication, each terminal needs to perform communication channel configuration and satellite information configuration in advance, and in the communication process, the channel state needs to be monitored in real time so as to realize stable satellite communication.
Based on the above application scenario, please refer to fig. 2, which is a flowchart of a method for terminal networking provided in an embodiment of the present application, where the method may be applied to any one terminal in a terminal command system, and the method includes:
step 101: and sending the exploration information to a plurality of terminals in a preset terminal list.
Step 102: terminal level information of a plurality of terminal responses is received.
Step 103: and determining the center terminal with the highest terminal level based on the terminal level information and the terminal level information of the center terminal.
Step 104: if the central terminal is not self, establishing a networking relation with the central terminal.
In the embodiment of the application, by pre-configuring the terminal level of each terminal, when the communication networking is performed, for the terminal with the non-highest terminal level, only the networking relation with the terminal with the highest terminal level is needed to be established, and the terminal with the highest terminal level can be regarded as a command center so as to ensure that the subsequent command tasks can be smoothly executed. Compared with the prior art, each terminal is configured with a terminal level, based on the terminal level, each terminal can establish a networking relation with the terminal with the highest terminal level, and the networking relation in the terminal command system is associated with the terminal level in a mode that only the terminal level exists, so that each terminal in the system can flexibly select a central terminal to carry out networking based on the terminal level at any time, the central terminal is further used as a command center, and the central terminal and each terminal of the networking execute related command tasks, so that the flexibility of terminal networking in the terminal command system is ensured.
Next, a detailed implementation procedure of the networking method and steps 101-104 will be described.
In step 101, the terminal sends probe information to a plurality of terminals in a preset terminal list. The preset terminal list may be understood as that before executing the command task, each terminal required by the command task is already determined, then a terminal list is generated according to the determined information of each terminal, and then the terminal list is imported into each terminal, so that the information of the terminal executing the task is stored on each terminal. The information of the terminal includes, but is not limited to: the ID (Identity document, identity) of each terminal, IP (Internet Protocol ) address, audio and video parameters, channel status, satellite information configuration, and the like.
Further, based on the preset terminal list, each terminal sequentially sends probe information to each terminal in the terminal list according to the IP address in the terminal list, wherein the probe information can comprise the IP address of the terminal and a terminal level information acquisition request, so that the terminal receiving the probe information can respond according to the probe information and feed back corresponding terminal level information.
On each terminal, terminal level information is stored in addition to the terminal list. For the terminal level information, it is understood that the higher the level, the more rights the respective terminals have in all the terminals participating in the task at this time. Since the scheme in the embodiment of the application relates to the central terminal, in order to ensure the uniqueness of the central terminal, the level of each terminal is unique, i.e. no terminal with the same terminal level exists. Each terminal can store the terminal level information and the height relation of the terminal level, so that each terminal can determine the terminal with the highest level according to different terminal levels.
In addition, there may be different setting manners for the terminal level information. Such as: assuming a total of 10 terminals, the terminal levels of each of the 10 terminals may be determined by: 001 002, 003, 004, 005, 006, 007, 008, 009, 010. Correspondingly, the terminal level may be: the higher the level of the terminal before the serial number, or the higher the level of the terminal after the serial number. In practical application, the setting can be flexibly performed according to the practical application scene, and the setting is not limited to the examples in the embodiment of the application.
Taking the vehicle command system shown in fig. 1 as an example, before a plurality of communication command vehicles go out of a task, a communication command vehicle list of the task, namely basic information of the communication command vehicles A-F and the communication command vehicles A-F, is uniformly imported into each communication command vehicle. And importing its own vehicle level information on each communication command vehicle, such as: the communication command vehicle A has the highest vehicle level, and is followed by the communication command vehicle B, the communication command vehicle C, the communication command vehicle D, the communication command vehicle E and the communication command vehicle F in sequence. Taking the communication command vehicle C as an example after each communication command vehicle arrives at a task site (such as a specific combat or drill site), the communication command vehicle C sends probe information to the communication command vehicle a, the communication command vehicle B, the communication command vehicle D, the communication command vehicle E and the communication command vehicle F according to the information of other communication command vehicles which are imported in advance.
Further, after the step 101 is performed, each terminal that receives the probe information responds to the probe information based on its own terminal level information, that is, sends its own terminal level information to the sending end of the probe information, at this time, the terminal performs step 102 to receive terminal level information responded by multiple terminals.
Taking the vehicle commanding system shown in fig. 1 as an example, the communication commanding vehicle a, the communication commanding vehicle B, the communication commanding vehicle D, the communication commanding vehicle E and the communication commanding vehicle F send respective vehicle level information to the communication commanding vehicle C after receiving the probe information. Referring to fig. 3 and fig. 4, which are schematic diagrams of communication links of the communication command vehicle C and the communication command vehicle D when probing the vehicle level information, it can be seen that the communication command vehicles C and D respectively communicate with other communication command vehicles to obtain corresponding vehicle level information.
Further, after step 102, step 103 is performed to determine the center terminal with the highest terminal level based on the terminal level information and the terminal level information of itself. As an alternative embodiment, the step comprises: and determining the center terminal with the highest level according to the preset relation between the terminal level and the low level. Such as: assume that terminal levels of other terminals are respectively: 001 003, 004, 005, 006, 007, 008, 009, 010, the terminal level of itself is 002, and the terminal level height relationship is: the terminal with terminal level 001 can be determined as the center terminal as the terminal with the higher sequence number is.
Taking a vehicle command system as an example, for the communication command vehicle C, assuming that the vehicle level of the communication command vehicle a-communication command vehicle F is higher than the communication command vehicle level preceding according to the serial number, the center vehicle determined by the communication command vehicle is: communication command car a.
It will be appreciated that for each terminal, there are two cases for the determined central terminal, one being: the terminal with the highest level is the center terminal; another case is: the central terminal is the other terminal.
For the second case, the central terminal is another terminal, step 104 is executed at this time, and if the central terminal is not itself, a networking relationship is established with the central terminal. When establishing the networking relation, as an optional implementation manner, the terminal sends the registration signaling to the central terminal, and after the central terminal receives the registration signaling, the terminal needing to establish the networking relation is added into the command network to establish the networking relation. After the networking relation is established, each terminal keeps heartbeat connection with the central vehicle at any time while carrying out service, and monitors the state of the networking relation in real time.
Taking a vehicle command system as an example, assuming that the communication command vehicle C determines the communication command vehicle A as a central vehicle, the communication command vehicle C sends registration signaling to the communication command vehicle A, and the communication command vehicle C is added into a command network after receiving the registration signaling to establish a networking relationship. Meanwhile, for the rest communication command vehicles, the rest communication command vehicles are added into the command network of the communication command vehicle A in the same way as the communication command vehicle C, and the final formed network topology diagram can be shown in figure 5.
For the first case, the operations performed on the terminal at this time may be: if the central terminal is self, when the probe information sent by a plurality of terminals is received, the terminal level information of the central terminal is sent to the plurality of terminals; receiving networking requests sent by a plurality of terminals; based on the networking request, a networking relationship is established with the plurality of terminals.
In this case, even if the terminal is the center terminal, the probe information sent by each terminal is received, after the terminal level information is fed back, the other terminals determine that the terminal is the center terminal, send a networking request (i.e., the registration signaling described in the foregoing embodiment), and then add the terminal that sends the networking request to the command network according to the networking request, so as to realize establishment of the networking relationship.
It should be understood that, since the central terminal in the embodiment of the present application may not be fixed, for each terminal, there are two cases after determining the central terminal each time, which case is satisfied, and which case corresponds to the execution of the flow corresponding to which case.
In the embodiment of the application, for the central terminal, if the probe information sent by other terminals is received, after the terminal level information is fed back, the other terminals initiate a networking request, and the central terminal establishes a networking relationship with the other terminals based on the networking request, so that flexible networking is realized.
Further, in the foregoing embodiment, it is mentioned that the central terminal may exit the command network halfway for some reason (such as a failure) and cannot override the role of the central terminal. Because each terminal monitors the network topology state in real time through heartbeat connection after networking is established, the exit condition of the central terminal can also be monitored, and when the condition occurs, the method further comprises the following steps: when the group gateway system with the center terminal fails, sending the probing information to terminals except the center terminal in a preset terminal list; receiving terminal level information of a terminal response except for a center terminal; determining a new center terminal with the highest terminal level in terminals except the center terminal based on the terminal level information and the terminal level information of the new center terminal; if the new center terminal is not self, establishing a networking relation with the new center terminal.
It should be noted that this embodiment is limited to non-central terminal execution, and for central terminals, no operation is performed after exiting the network, so this procedure is only applicable to the subsequent procedure of the case defined in step 104.
When the group gateway system with the central terminal fails, although the level information of each terminal acquired before is stored in each terminal, the situation that each other non-central terminal exits is possible, so that more accurate terminal level information needs to be acquired again through the probe information at the moment, and the situation that the determined new central terminal may also exit the task is avoided.
The above-described embodiment of determining a new central terminal and establishing a network is the same as that of the foregoing embodiment, and will not be repeated here.
In the embodiment of the application, after the group gateway system with the central terminal fails, a new central terminal can be determined again based on the terminal level information, so that a new group gateway system is established, and based on the new networking relation, the command task is continuously executed.
In addition, for the new central terminal, the implementation flow is as follows: if the new center terminal is self, when the probe information sent by the terminal except the center terminal is received, the terminal level of the self is sent to the terminal except the center terminal; receiving networking requests sent by terminals except the center terminal; based on the networking request, a networking relationship is established with terminals other than the center terminal.
In the embodiment of the application, for the new central terminal, based on the networking request of other terminals, the networking relation is established with other terminals, so that flexible networking is realized.
Taking the vehicle command system shown in fig. 1 as an example, after the communication command vehicle a exits the task, the new central vehicle is the communication command vehicle B, and the network topology diagram at this time can be shown in fig. 6; further, if the communication command vehicle B also exits the task for some reason, the new center vehicle is the communication command vehicle C, and the network topology diagram at this time may be as shown in fig. 7. It can be seen that after the central vehicle gets off the network, a new central vehicle takes over, so that the stable and flexible networking relation in the vehicle command system can be completely ensured.
In addition, for the terminal which has moved out of the network, since the command tasks are all planned in advance, even if the terminal which subsequently moves out of the network is in a state of being restored, the terminal which has moved out of the network is inconvenient to be re-added into the command network, and therefore, the terminal which has moved out of the network cannot be added into the previous command tasks, but can be assigned to participate in new tasks.
Based on the networking method introduced in the foregoing embodiment, after the terminals in the terminal command system establish the networking relationship, their respective command tasks may be started. In the process of conducting command tasks, video and audio communication is a common command mode, namely, the networking method can provide networking support for the service. An embodiment of the video/audio communication based on the gateway system of the center terminal-other terminal group will be described.
Assuming the terminal is a central terminal, after establishing the networking relationship, the method further comprises: receiving an initiating request of a viewing audio conference; creating a video-audio conference corresponding to the initiation request; and generating invitation information corresponding to the video-audio conference, and sending the invitation information to the plurality of terminals so that the plurality of terminals join the video-audio conference through the invitation information.
The initiation request may be a request initiated by a user corresponding to the central terminal, where the initiation request may include information of the video-audio conference, for example: meeting time, meeting topic, etc. After the central terminal receives the request, a corresponding video-audio conference is created based on the information, such as: and the conference time is 9:00-12:00, and when the central terminal is 9:00, the video-audio conference is created. Further, after creation, corresponding invitation information is generated, and in the invitation information, may include: indication information for joining an audio-visual conference, such as: video audio conference links, or addresses, etc. After the invitation information is generated, the central terminal synchronizes the invitation information to each terminal in a signaling manner so that each terminal can join in the video-audio conference through the invitation information. This section is consistent with the implementation of video-audio conferences in the art, and the implementation principles thereof are not specifically described herein.
In the embodiment of the application, after the networking relation is established between the central terminal and other terminals, each terminal of the networking can be invited to join in the video-audio conference, so that the video command function is realized, and the high efficiency and convenience of command are improved.
Further, assuming that the terminal is not a central terminal, after establishing the networking relationship, the method further includes: receiving invitation information of a video-audio conference sent by a center terminal; responding to the invitation information, and joining a video-audio conference; and sending the video and audio data acquired in real time to a center terminal.
In this embodiment, the non-central terminal may display the invitation information after receiving the invitation information, and the user corresponding to the non-central terminal may choose to receive the request, and after receiving the acknowledgement of the user, respond to the invitation information based on the acknowledgement of the user, for example: and jumping to the video-audio conference corresponding to the link to realize the joining of the video-audio conference.
In the embodiment of the application, for the non-central terminal, after the networking relation is established, after the invitation information of the video-audio conference is received, the video-audio conference is added by responding to the invitation information, and the video-audio data acquired in real time is sent to the central terminal, so that the video command function is realized, and the high efficiency and convenience of command are improved.
Whether the terminal is a central terminal or a non-central terminal, after the video-audio conference starts, corresponding prompt options can be displayed on the corresponding user interface, for example: camera on/off, microphone on/off, etc., as a conference initiation terminal, a higher authority prompt option like whole person silence, etc. may also be presented for the center terminal. For these prompt options, after the user makes a selection or confirmation, the terminal or the center terminal performs an operation corresponding to the option.
Based on the selection of each prompt option by the user, the terminal can execute operations of starting the camera, starting the microphone and the like, and after the camera, the microphone and the like are started, the terminal can acquire video and audio data in real time. For the central terminal, the collected video and audio data are directly displayed; for the non-central terminal, the video and audio data collected in real time are sent to the central terminal. It will be appreciated that the non-central terminal may encode the video and audio data to obtain an encoded stream, send the data to the central terminal in the form of a code stream, and after receiving the code stream data, the central terminal decodes the code stream data and then displays or plays the code stream data.
Further, the executable procedure on the central terminal further includes: receiving video and audio data sent by a plurality of terminals; the video and audio data are played after being combined according to preset rules; and sending the screen combination data to a plurality of terminals, and eliminating the sound data corresponding to the screen combination data received by the terminals.
In this embodiment, since the plurality of terminals transmit the plurality of video and audio data, in order to improve the viewing experience, the plurality of video and audio data may be played after being combined with the screen. When the screen is closed, the screen can be closed based on a preset rule. The preset rule may be understood as a rule that different pictures are combined and displayed on one screen. Such as: there are a number of ways in which 5 frames are arranged on a screen, and these ways can be understood as the rule of combining screens. The screen combination rule may be set according to the number of video and audio data, for example: if the video and audio data of the central terminal are added, and a total of 9 video and audio data are added, the screen combining rule may be nine Gong Gege screen rules, namely, 9 grid areas are defined in advance, then the playing areas of the 9 video and audio data are sequentially limited to all areas of the 9 grid areas, and when playing, the corresponding video and audio data can be played in all areas. Wherein, the playing area of the video and audio data of the central terminal can be arranged in the middle area of the 9-grid area. In the embodiment of the application, for the central terminal, the central terminal performs the screen closing processing according to the preset rule and then plays the screen closing processing, and the corresponding user of the central terminal can adjust the area of each played picture at any time later, namely, the preset rule is only a default rule, and the subsequent processing process can perform real-time updating.
Further, the central terminal also needs to send the screen combination data to a plurality of terminals, and the sound data corresponding to the screen combination data received by the terminals are removed. In this embodiment, the central terminal completes the screen combination, encodes based on the video and audio data played by the screen combination, and generates secondary video and audio data encoded by the screen combination. And the central terminal also performs sound eliminating processing on the screen combination data sent to each terminal. For example: the communication command vehicle A sends the screen combination data of the communication command vehicle B, the sound data of the communication command vehicle B is not generated, and the screen combination data of the communication command vehicle C is sent to the screen combination data of the communication command vehicle C, so that the sound data of the communication command vehicle C is not generated.
When rejecting, because the data sent by each terminal is sent through a specific channel or port, the center terminal can directly reject the data according to the channel or port source of each sound data. Such as: aiming at the screen combination data to be sent to the communication command vehicle B, the communication command vehicle A removes the sound data of the source and the communication command vehicle B.
In the embodiment of the application, for the central terminal, the video and audio data of each terminal can be subjected to screen combination processing, the central terminal receives each path of data and sends the screen combination data, so that the pressure of the central terminal is reduced, and the stability of the networking relationship in the command system can be ensured under the condition of smaller pressure of the central terminal.
Further, for the non-central terminal, the executable flow further includes: receiving the screen combination data sent by the center terminal; the screen combination data are data obtained after screen combination is carried out on video and audio data acquired by each terminal participating in the video and audio conference, and the screen combination data do not comprise sound data in the video and audio data acquired by the terminal; and playing the video and audio corresponding to the screen-closing data.
In this embodiment, after receiving the screen combination data, the non-central terminal decodes the screen combination data and plays the screen combination data, and the audio and video data played at this time cannot include sound data in the audio and video data acquired by itself due to the fact that the audio and video data are removed.
In the embodiment of the application, for the non-center terminal, the received combined screen data does not include the sound data in the video and audio data acquired by the non-center terminal, and when the non-center terminal plays, the mixed video and audio data can be prevented from having an echo effect (the sound in the current environment appears).
In the process of the video-audio conference, assuming that the central terminal is out of the network, each terminal can immediately re-determine a new central vehicle, then establish a network with the new central vehicle, and the new central vehicle can replace the out-of-network central vehicle to re-organize the video-audio conference, so that the normal operation of command tasks is ensured.
Through the description of the embodiment, it can be seen that the networking mode without the fixed center terminal provided by the embodiment of the application can stably and flexibly help the completion of various command tasks.
