The embodiment of the application discloses a data synchronization method which is used for a screen display system. The screen display system comprises at least two terminals, each terminal corresponds to one physical small screen, and the physical small screens are spliced into one physical large screen. And each terminal sends the data of the terminal to the small physical screen for display, and finally, the overall display effect is formed in the large physical screen. How to keep the data display synchronization in each physical small screen is a technical problem to be mainly solved by the data synchronization method of the embodiment.

As will be appreciated by those skilled in the art, the following specific embodiments are merely illustrative and are not further limiting on the present step 101.
In a specific implementation, a websocket protocol connection is established between the terminal and the server in this embodiment. The websocket Protocol is a network Protocol based on a Transmission Control Protocol (TCP), and implements full-duplex (full-duplex) communication between a browser and a server, which allows the server to actively send information to a terminal.
The server implements the server side program using nodejs (sds). Nodejs is a Javascript operating environment (runtime), released in 5 months of 2009, developed by Ryan Dahl, and essentially encapsulates Chrome V8 engine.
102. And receiving a setting instruction of the server, setting one of the at least two terminals as a sending terminal, and setting the rest of the at least two terminals as receiving terminals.
Specifically, referring to fig. 2, this step 102 includes:
201. and the at least two terminals respectively send connection instructions to the server.
Wherein, the connection instruction (join) comprises: room number (room) of the terminal, page information of the terminal; the page information of the terminal comprises: the page name (page) of the terminal, the page identifier (page id) of the terminal, and the network address (search) of the page of the terminal.
It should be noted that the purpose of the connection instruction (join) is not to establish a connection between the server and the terminal in step 101, but to implement setting of whether the terminal is a sending terminal or a receiving terminal by the server. The connection instruction is a precondition for triggering the server to issue the setting instruction.
202. And the at least two terminals receive a first setting instruction sent by the server.
Wherein the first setting instruction includes: is set as the page identification of the transmitting terminal.
203. Each of the at least two terminals checks whether the page identifier of the sending terminal in the first setting instruction is the same as the page identifier of the sending terminal, if so, step 204 is executed, and if not, step 205 is executed.
204. The terminal sets itself as a transmitting terminal.
205. The terminal sets itself as a receiving terminal.
In summary, it may be set as a sending terminal or a receiving terminal for each terminal, depending on the setting of the server.
In addition, in the using process, an abnormality may occur in the connection between the sending terminal and the server, and there may be various reasons for the abnormality, such as the sending terminal itself crashes, network congestion, and the like. In this case, the server needs to reselect one of the remaining receiving terminals as the transmitting terminal, and continue to implement the data synchronization method of the present application.
Specifically, after the sending terminal is abnormally connected with the server, the method further includes:
2011. and at least two receiving terminals re-receive the second setting instruction sent by the server. Wherein the second setting instruction includes: and the page identifier of the sending terminal is reset in at least two receiving terminals.
2012. And each of the at least two receiving terminals checks whether the page identifier of the sending terminal in the second setting instruction is the same as the page identifier of the sending terminal, if so, step 2013 is executed, and if not, step 2014 is executed.
2013. The receiving terminal resets itself as the transmitting terminal.
2014. The receiving terminal does not make any setting and keeps itself as the receiving terminal.
By this step 102, the setting of the transmitting terminal and the receiving terminal is completed.
103. And the sending terminal generates a data synchronization instruction by the synchronization data and sends the data synchronization instruction to the server.
In this embodiment, the data synchronization instruction (sync) includes: transmitting a page name (page), a display component name (component), and synchronization data (data) of the terminal;
the synchronization data includes: the data (state) of the component is displayed.
It should be explained that the screen display system referred to in this embodiment is essentially a web page system, and each terminal corresponds to a page, and the page is correspondingly displayed in a physical small screen. The page of each terminal is composed of various display components, the display components have different states, and the corresponding display effect of each state (state) can be different, so that the data (state) of the display components can be designed according to the service requirement, and only the data (state) of the display components need to be synchronized during synchronization, thereby reducing the transmitted data amount and improving the processing efficiency.
In this embodiment, the data (state) of the display component is a UI data model of the display component, and is a data basis for rendering the display component.
104. And the receiving terminal receives a data synchronization instruction issued by the server and displays the synchronization data according to the data synchronization instruction.
Specifically, referring to fig. 3, this step 104 includes:
301. and the receiving terminal searches the corresponding display component according to the display component name.
302. And the receiving terminal sets the display state of the display assembly according to the data of the display assembly so as to display the effect of the display assembly.
The above is a method of data synchronization on the terminal side in the present embodiment, and a method of data synchronization on the server side in the present embodiment is described in detail below.
The embodiment discloses a data synchronization method for a server, referring to fig. 4, including steps 401 to 403:
401. and sending a first setting instruction to at least two terminals belonging to one screen display system, so as to set one of the at least two terminals as a sending terminal and the rest of the at least two terminals as receiving terminals.
Specifically, referring to fig. 5, the step 401 specifically includes steps 501 to 502:
501. and the server receives the connection instruction and updates the connection information of the terminal.
Wherein the join instruction (join) comprises: room number (room) of the terminal, page information of the terminal;
the page information of the terminal comprises: the page name (page) of the terminal, the page identifier (page id) of the terminal, and the network address (search) of the page of the terminal.
Specifically, this step 501 specifically includes:
5011. and the server judges whether the room number of the terminal in the connection instruction is prestored, and if not, the room number is created.
5012. And the server judges whether the page of the terminal is connected for the first time according to the page identification of the terminal, if so, the page information of the terminal is newly added, and if not, the prestored page information of the terminal is updated.
502. The server selects one of the at least two terminals with the same room number and the same page name as a sending terminal, selects the rest of the at least two terminals with the same room number and the same page name as receiving terminals, and sends a first setting instruction to the at least two terminals with the same room number and the same page name.
Wherein the first setting instruction includes: and setting the page identifier as the page identifier of the sending terminal.
As can be seen from step 502, terminals with the same room number and the same page name can communicate with each other, and terminals that are not in the same room number and have different page names will not affect each other.
Optionally, in actual use, a situation that the connection between the sending terminal and the server is abnormal may occur. In this case, the server needs to reselect one terminal as a transmitting terminal among the receiving terminals. The server may select the sending terminal in various ways, for example, randomly.
If the server detects that the connection with the sending terminal is abnormal, this step 401 further includes:
503. the server reselects one of the at least two receiving terminals with the same room number and the same page name as a sending terminal, and sends a second setting instruction to the at least two receiving terminals with the same room number and the same page name; wherein the second setting instruction includes: is reset to the page identification of the transmitting terminal.
This step 401 is executed, and the server completes the setting of the transmitting terminal and the receiving terminal.
402. And receiving a data synchronization instruction which contains synchronization data and is sent by the sending terminal.
The foregoing embodiments have been described in detail with respect to the composition of the data synchronization instruction, and are not described herein again.
403. And sending the data synchronization instruction to the receiving terminal so that the receiving terminal displays the synchronization data according to the data synchronization instruction.
It should be noted that, in this step 403, the server does not process the data synchronization instruction, but directly forwards the data synchronization instruction to the receiving terminal, so as to improve the processing efficiency of the server.
In this step, the server may determine the receiving terminal that needs to forward the data synchronization instruction based on the room number (room) of the terminal and the page identifier (pageid) of the terminal in the connection instruction.
According to the data synchronization method, one terminal in the screen display system is set to be the sending terminal through the server, the other terminals are the receiving terminals, then the sending terminal sends the synchronization data to the receiving terminals, and the data synchronization is achieved, so that the problem that the playing progress of each terminal is inconsistent is solved, and the user experience is improved.
By the method of the embodiment, when a plurality of terminals need to perform data synchronization, only one terminal is a sending terminal, and the other terminals are receiving terminals, which is because the data display is a continuous schedule, and if the plurality of terminals perform synchronization, the data display is easily disordered. Therefore, only one sending terminal can send data, and other terminals are responsible for receiving and displaying, so that the display effect of all the terminals is consistent.
For a more detailed description of the solution of the embodiments of the present application, refer to fig. 6. It should be noted that only one terminal is shown in fig. 6, there are at least two terminals in this application, and the method steps performed by each terminal are the same as the method steps performed by the terminal shown in fig. 6.
