Example 1
Referring to fig. 2, fig. 2 is a flow chart of a control method of a multimedia performance device according to an embodiment of the present application, and the method can be applied to the control center 10 shown in fig. 1. As shown in fig. 2, the control method of the multimedia performance device may include the following steps:
201. And acquiring time axes corresponding to the N control nodes respectively.
In the embodiment of the application, each control node corresponds to at least one time axis, and the time axis comprises multimedia control data corresponding to at least one time node. Wherein the multimedia control data may comprise multimedia material files and/or multimedia control instructions. The multimedia material files may include, but are not limited to: musical material files, video material files, light material files, brightening material files and mechanical material files. The multimedia control instruction is used for controlling the multimedia curtain wall and each subsystem included in the control node.

That is, as an alternative embodiment, before executing step 501, the time axes corresponding to the N control nodes may be generated according to the user operation input by the user in the man-machine interaction interface of the control center 10. Specifically, the method comprises the following steps:
outputting and displaying a time axis editing area in a man-machine interaction interface of the control center 10; the time axis editing area is used for editing a time axis corresponding to any one of the N control nodes, and the time axis editing area can be a certain display area on a human-computer interaction interface, so that a user can drag a multimedia control data icon into the time axis editing area;
Detecting the selection operation of a user for the multimedia control data icon in the man-machine interaction interface;
Determining the placement position of the multimedia control data icon on the time axis editing area according to the selection operation;
And determining a time node on a time axis according to the placement position, and determining a corresponding relation between the time node and multimedia control data corresponding to the multimedia control data icon.
For example, please refer to fig. 3 together, fig. 3 is an exemplary diagram of a man-machine interface according to an embodiment of the present application. By implementing the embodiment, the time axis can be edited graphically, so that the user operation is simplified, and the editing efficiency of the time axis is improved.
202. And transmitting the multimedia control data to the N control nodes according to the time nodes on the time axes corresponding to the N control nodes.
In the embodiment of the present application, the control center 10 may utilize a timer to time, and when the time reaches a time node corresponding to multimedia control data on a certain time axis, the control center 10 sends corresponding multimedia control data to the control node 30 corresponding to the time axis, so that the control node performs a corresponding operation in response to the received multimedia control data.
For example, please refer to fig. 4A together, fig. 4A is an exemplary diagram of a time axis corresponding to a control node according to an embodiment of the present application. If the multimedia curtain walls included in the control node 30 and the control node 31 need to be synchronously exhibited, the time axis 1 corresponding to the control node 30 and the time axis 2 corresponding to the control node 31 may be as shown in fig. 4A. At the current time is 00:00, the control center 10 simultaneously sends the acousto-optic and electric equipment control instruction 1 to two control nodes according to the time axis 1 and the time axis 2, and when receiving the acousto-optic and electric equipment control instruction 1, the control node 30 triggers the acousto-optic and electric equipment included in the control node 30 to execute corresponding operations; similarly, when the control node 31 receives the acousto-optic and electric system control instruction 2, the acousto-optic and electric equipment included in the control node 31 is triggered to execute corresponding operation, so that the effect of synchronous exhibition of the acousto-optic and electric equipment of the control node 30 and the node 31 can be achieved. In this example, control node 30 and control node 31 exhibit the same program content. It should be noted that, in other possible examples, the control node 30 and the control node 31 may also be used to present different program contents based on different time axes.
For example, please refer to fig. 4B together, fig. 4B is an exemplary diagram of a time axis corresponding to another control node according to an embodiment of the present application. If the multimedia curtain walls included in the control node 30 and the control node 31 need to sequentially display different playing contents, the time axis 1 corresponding to the control node 30 and the time axis 2 corresponding to the control node 31 may be as shown in fig. 4B. At the current time is 00:00, the control center 10 sends the video material 1 to the control node 30 according to the time axis 1, and when the control node 30 receives the video material 1, the control node 30 can output the video material 1 through the curtain wall display end of the control node 30. When the video material 1 is completely played, the current time is 01:00, the control center 10 sends the video material 2 to the control node 31 according to the time axis 2, and when the control node 31 receives the video material 2, the video material 2 can be output through the curtain wall display end of the control node 31, so that the exhibition effect that the control node 30 and the control node 31 are smoothly connected can be achieved.
Therefore, by implementing the method provided by the embodiment, the control center can manage the control nodes where the plurality of multimedia curtain walls are located, the control center controls the time, and the control center issues the multimedia control data according to the time axes corresponding to the control nodes, so that the play synchronism and the connection smoothness among the plurality of multimedia curtain walls can be improved, and the problems of asynchronous play and unsmooth connection among the multimedia curtain walls caused by asynchronous local time of the control nodes are reduced.
Example two
Referring to fig. 5, fig. 5 is a flowchart illustrating a control method of another multimedia performance device according to an embodiment of the present application, and the method may be applied to the control center 10 shown in fig. 1. As shown in fig. 5, the control method of the multimedia performance device may include the following steps:
501. And detecting a starting instruction input by a user.
502. Communication connection between the N control nodes instructed to start by the user and the control center 10 is established according to the start instruction.
Referring to fig. 6 together, fig. 6 is an exemplary diagram of another man-machine interface according to an embodiment of the present application. The centralized control end of the control center 10 can output a man-machine interaction interface as shown in fig. 6, and an on-power key, an off-power key, the current time, the on-off state of the control node and the like are displayed in the man-machine interaction interface. Through the man-machine interaction interface shown in fig. 6, a start instruction input by a user through triggering an "on button" can be detected. As shown in fig. 6, the user instructs to activate three control nodes "region B1", "region B2", "region B3 laser", the control node "region B3" being in an off state. In performing step 503 described below, the control center 10 may acquire the time axes corresponding to the three control nodes in the on state, respectively, instead of the time axes corresponding to the control nodes in the off state. That is, the user can centrally manage each control node through the control center by performing the above steps 501 to 502.
503. And acquiring time axes corresponding to the N control nodes respectively.
In the embodiment of the present application, as an optional implementation manner, each control node may correspond to at least one time axis; each time axis can correspond to a program which is participated in display by one control node, and the starting time of the time axis is the starting playing time of the program which is participated in display by the corresponding control node. By implementing the embodiment, independent time axes can be generated for different programs which are participated in display by the control node, so that the problem of playing conflict caused by sharing one time axis by a plurality of programs can be reduced.
For example, referring to fig. 7, fig. 7 is an exemplary diagram of a time axis corresponding to another control node according to an embodiment of the present application. As shown in fig. 7, the control node 30 corresponds to two time axes, namely, a time axis 1 and a time axis 3, where the time axis 1 corresponds to the program 1 that the control node 30 participates in displaying, and the time axis 3 corresponds to the program 2 that the control node 30 participates in displaying. The starting play moments of program 1 and program 2 are different, and therefore the starting moments of time axis 1 and time axis 3 are different. For example, the starting playing time of the program 1 may be 00 on the working day: 00, the starting playing time of the program 2 may be 00 on the weekend: 55. as can be seen from fig. 7, if the control node 30 shares the same time axis with the program 1 and the program 2 that participate in the presentation, the multimedia control data corresponding to the program 1 and the program 2 respectively may overlap partially or completely on the time axis, which easily causes a play conflict. As shown in fig. 7, two time axes are generated for the program 1 and the program 2 respectively, so that the problem of the play conflict can be solved. Further, as shown in fig. 7, the control node 31 corresponds to the time axis 2, and the time axis 2 corresponds to the program 1 that the control node 2 participates in the presentation, that is, the control node 30 and the control node 31 participate in the presentation of the program 1 together. Further optionally, in the embodiment of the present application, before executing step 503, any one of the following implementations may be further executed to generate time axes corresponding to the N control nodes:
Embodiment one: when M control nodes in the N control nodes participate in playing the same program, respectively generating M time shafts corresponding to the M control nodes; the starting time of the M time axes is the starting playing time of the same program;
Embodiment two: when any one of the N control nodes participates in playing K different programs, generating K time shafts for each control node which participates in playing K different programs; k is a positive integer greater than or equal to 2, and the starting time of the K time axes is K different playing starting time respectively.
In addition to the above two automatic time axis generation methods, in the embodiment of the present application, the time axes corresponding to the N control nodes may be manually edited and generated by the user. Therefore, in the embodiment of the present application, the starting time of the corresponding time axis when the control node participates in a certain program may be the same as the starting playing time of the program, and the starting time may also be before the starting playing time of the program. If the starting time of the time axis is before the starting playing time of the program, a blank area exists between the time node corresponding to the starting time of the time axis and the time node of the first multimedia control data, and the blank area can be used for controlling delay.
504. And determining a target time axis corresponding to a target control node participating in the program to be displayed according to the starting time of the time axis corresponding to each of the N control nodes and the starting playing time of the program to be displayed.
