In an embodiment, as shown in fig. 2, a multimedia light linkage playing method is provided, which is described by taking the example that the method is applied to the server in fig. 1, and includes the following steps:
The multimedia playing plan can be a plan which is preset by a user and is used for linkage playing among multiple buildings, and is mainly used for stipulating a program to be played and corresponding playing time. Specifically, the multimedia playing plan includes a scheduled playing program and a corresponding program identifier, a program playing start time, and a program playing end time, and the scheduled playing program may be one or more of a specific scheduled playing image, a specific video, a specific audio, and a specific text. In this embodiment, after receiving a multimedia playing plan preset by a user, the following steps are performed to control a plurality of accessed nodes, so as to implement linked playing of the plurality of nodes.
In this embodiment, each node is further connected to a controlled luminaire for controlling the corresponding luminaire to display a light scene according to the control command. Specifically, after receiving a multimedia playing plan preset by a user, the multimedia playing plan is sent to a plurality of nodes accessed, so that the plurality of nodes respectively store the multimedia playing plan to the local.
And step 206, sending a playing command to the plurality of nodes so that the plurality of nodes display the corresponding light scene according to the playing command.

According to the multimedia light linkage playing method, the multimedia playing plan customized by the user is received, and the multimedia playing plan is sent to the plurality of connected nodes, so that each node stores the corresponding playing source to the local, the local playing source can be searched after each node receives the playing command, and the corresponding lamp is controlled to display the light scene according to the playing command.
In one embodiment, as shown in fig. 3, before sending the play command to the plurality of nodes, the method further includes the following steps:
The time service signal is a standard time signal for keeping the time of each node consistent, that is, keeping the time of each node as the standard time. In this embodiment, in order to further improve the synchronization of the playing effect of each node, the time of each node is kept consistent through the time service signal, so that when each node displays the corresponding lighting scene according to the playing command, the program playing start time and the program playing stop time can also be kept consistent, and the playing effect of each node can be completely synchronized.
The specific implementation principle is shown in fig. 4, in which a master (i.e., a server) and a plurality of slaves (i.e., nodes) communicate via a network, a time service signal is provided by a time service server, the time service server can provide time service to each slave via the connected master, or the time service server can directly provide time service to the connected master and each slave, which is not limited in the present application. In this embodiment, each slave machine is connected to a controlled lamp to control the lamp to display a light scene, and the master machine can receive a multimedia playing plan customized by a user and send the multimedia playing plan to the connected slave machines, so that each slave machine stores a corresponding playing source to the local, and thus, after receiving a playing command sent by the master machine, the local playing source can be searched to control the corresponding lamp to display the light scene according to the playing command. Due to the time synchronization of the slave machines, the synchronous playing effect can be achieved.

and step 208, sending a play control instruction to the plurality of nodes so that the plurality of nodes perform play control according to the play control instruction.
The playing control instruction comprises any one of a pause playing instruction, a continuous playing instruction, a fast forward playing instruction, a backward playing instruction, an exit playing instruction and a switching playing instruction. In this embodiment, under the condition that it is ensured that the host is normally connected to each node, the host may send the play control instruction to each connected node, so that each node performs play control according to the play control instruction. For example, if the play control instruction is a pause play instruction, the node pauses the program currently being played after receiving the play control instruction; if the playing control instruction is a continuous playing instruction, the node continues playing according to the program at the last stopping moment after receiving the playing control instruction; if the playing control instruction is a fast forward playing instruction, the node receives the playing control instruction and then fast-forwards plays the program which is currently played; if the playing control instruction is a switching playing instruction, the node receives the playing control instruction and then switches the program which is currently played according to the instruction. Therefore, the playing control of each node is realized.
In one embodiment, as shown in fig. 6, before receiving the multimedia play plan, the method further includes the following steps:
step 602, receiving an access request of the mobile terminal, where the access request carries an access check identifier.

The access check identifier is used to check the validity of the access request, and may specifically be an identifier of the mobile terminal or an identity check code. In this embodiment, the mobile terminal may send an access request carrying an access check identifier to the target node through an HTTP (HyperText Transfer Protocol) Protocol or a Modbus (serial communication Protocol) Protocol.
The multimedia playing test command is used for testing the playing effect of the target node and comprises a test playing material instruction and a corresponding first playing mode instruction. Specifically, the test playing material instruction may be a program identifier for specifying a program to be tested and played, and specifically, after the mobile terminal establishes a connection with the target node, all program lists of the target node may be accessed, and which program is to be tested and played may be specified according to the program lists. Of course, the mobile terminal may also carry corresponding test program material in the test playing material instruction, which may be an image or a video, and the target node performs test playing according to the received test program material. The first play mode command includes any one of a loop play and a fixed duration play. In this embodiment, when the access check identifier sent to the mobile terminal passes the verification, it indicates that the access request is legal, and when the access check identifier sent to the mobile terminal fails the verification, it indicates that the access request is illegal.
And 606, controlling the corresponding lamp to display the light scene according to the test playing material instruction and the corresponding first playing mode instruction.
Specifically, only when the access request is determined to be legal, the multimedia playing test command sent by the mobile terminal is received, and then the corresponding lamp is controlled to display the light scene according to the test playing material instruction in the command and the corresponding first playing mode instruction, so that the field test and debugging are realized. Compared with the prior art that at least two persons are needed to complete the test and debugging (one person operates and controls the nodes indoors and one person watches the program effect outdoors), the efficiency of field test and debugging of workers is greatly improved.
In one embodiment, if the scheduled broadcast program has multiple frames, the multimedia broadcast schedule further includes a corresponding broadcast time sequence, a second broadcast mode command or a broadcast time sequence and a second broadcast mode command, where the broadcast time sequence specifies a broadcast sequence of the multiple frames and an ending broadcast time point of each frame, and the second broadcast mode command is used to indicate the number of cycles or duration of broadcast of each frame in the scheduled broadcast program. For example, if the scheduled broadcast program includes 3 frames of frames A, B and C, the corresponding broadcast time sequence defines the broadcast sequence of frames A, B and C and the ending broadcast time point of the corresponding broadcast frame. Specifically, after the node receives the corresponding play command, the corresponding pictures are played frame by frame at the start time of the program play according to the play sequence and the corresponding stop play time point, so that the play pictures of each node are synchronized to achieve a consistent play effect. If the cycle number or the playing duration of each frame of playing picture of the program scheduled to be played is appointed, playing each frame of playing picture according to the cycle number or the playing duration. In an embodiment, when the user sets the multimedia playing plan, the user may further designate a playing mode for each program scheduled to be played, for example, designate the program scheduled to be played at a fixed time of a certain day, or at a fixed time of a week, or at a fixed time of a month, so as to form a corresponding multimedia playing day plan, a multimedia playing week plan, or a multimedia playing month plan, or designate the program scheduled to be played randomly at a certain time, so as to form a corresponding multimedia playing temporary plan. It can be understood that the multimedia playing month plan may include a plurality of multimedia playing week plans, and the multimedia playing week plan may include a plurality of multimedia playing day plans, and when the multimedia playing plan is executed, the playing execution priority of the multimedia playing month plan is sequentially the multimedia playing temporary plan, the multimedia playing day plan, the multimedia playing week plan, and the multimedia playing month plan, that is, the playing priority of the multimedia playing temporary plan is the highest.
In one embodiment, the target node (including the host and each node) may further receive a mode switch instruction, where the mode switch instruction is used to instruct the target node to operate in the host mode or the node mode, where each node may be subjected to play control in the host mode. In addition, the target node can also receive the following play settings, such as whether to participate in linkage play, whether to lock a keyboard and a mouse during play, whether to customize a play window, the size of the play window and the like. Specifically, for the linked play, a certain area of the material specifically played by the nodes participating in the linked play may be designated, for example, the size of one material is 600 × 200, if three computers (i.e., 3 nodes) participate in the linked play of the material, 1/3 pictures in which the material is played by each node can be set, the start position and the end position of the picture played by each node are designated, and the pictures played by the 3 nodes form a complete material picture.
