[0043] Terminal control module: controls adjustable lamps based on lighting control parameters; monitors the stage scene to complete the update of historical data.

[0044] Next, the technical solution of this embodiment is described by way of example. This embodiment provides an intelligent lighting control system comprising the following steps:

[0045] 1. The data acquisition module obtains the historical data of the stage through archival records and transmits the historical data to the central analysis module; the central analysis module: extracts historical music data and historical lighting data from the historical data; identifies and analyzes the historical music data to obtain several atmosphere features; determines the atmosphere types corresponding to several atmosphere features, and marks several atmosphere types as i; matches the stage lights corresponding to the atmosphere label i from the historical lighting data, and sets the lighting label Dij for the matching stage lights.

[0046] For example: there are two groups of music data obtained, and the rhythm, tune and melody of the music are analyzed to obtain the atmosphere labels of the two groups of music as 2 and 3, among which the atmosphere corresponding to atmosphere label 2 is joy and happiness; the atmosphere corresponding to atmosphere label 3 is sorrow and sadness; the stage lighting numbers corresponding to the two groups of atmosphere labels are as follows: there are two types of stage lights corresponding to atmosphere label 2, and the stage lighting labels are D21 and D22 respectively; there are three types of stage lights corresponding to atmosphere label 3, and the stage lighting labels are D31, D32, and D33.

[0047] 2. Please refer to Figure 3 , simulate and set the atmosphere type i in turn, and simulate the stage light j in turn according to the light label Dij; count the audience's satisfaction vote on the effect of stage light j in each atmosphere type i, and mark the vote rate as DPLij; when the vote rate DPLij is greater than the set vote threshold, the corresponding stage light j will be included in the alternative experimental plan.

[0048] For example, there are three different stage lights corresponding to atmosphere tag 3, and 1,000 audiences are watching stage lights D31, D32, and D33 respectively; the vote threshold is set to 30%, and the audience votes on the stage lights after watching and obtains the following data:

[0049] The number of votes for stage lighting D31 is DPS31=350, so the vote rate for stage lighting D31 is DPL31=35%; if it is greater than the set vote threshold, stage lighting D31 will be included in the alternative experimental plan;

[0050] The number of votes for stage lighting D32 is DPS32=450, and the vote rate for stage lighting D32 is DPL32=45%; if it is greater than the set vote threshold, stage lighting D32 will be included in the alternative experimental plan;

[0051] The number of votes for stage lighting D33 is DPS33=200, and the vote rate for stage lighting D33 is DPL33=20%; if it is less than the set vote threshold, stage lighting D33 is excluded.

[0052] 3. Please refer to Figure 3 , extract the total number of viewers GWRij and the total number of people who left midway ZLRij from the historical audience data; among them, GWRij and ZLRij are the stage lights j corresponding to the atmosphere label i; the actual viewing rate GKLij is calculated by the formula GKLij=β×[(GWRij-ZLRij) / GWRij]; when the actual viewing rate GKLij is greater than the set viewing threshold, the corresponding stage light j is included in the alternative actual plan.

[0053] For example, there are three different stage lights corresponding to the existing atmosphere tag 3, β is set to 1, and the viewing threshold is set to 40%. The three sets of data are as follows:

[0054] Stage lighting D31: The number of people watching the stage GWR31 = 1500, and the number of people leaving the stage ZLR31 = 500, then the viewing rate of stage lighting D31 GKL31 = 66.7%, which is greater than the set viewing threshold, so stage lighting D31 is included in the alternative actual plan;

[0055] Stage lighting D32: The number of people watching the stage GWR32 = 3000, and the number of people leaving the stage ZLR32 = 1200, then the viewing rate of stage lighting D32 GKL32 = 60%, which is greater than the set viewing threshold, so stage lighting D32 is included in the alternative actual plan;

[0056] Stage lighting D33: The number of people watching the stage GWR33 = 1000, and the number of people leaving the stage ZLR33 = 500, then the viewing rate of stage lighting D33 GKL33 = 50%, which is greater than the set viewing threshold, so stage lighting D33 is included in the alternative actual plan.

[0057] 4. Please refer to Figure 3 , extract the vote rate DPLij and actual viewing rate GKLij of stage light j corresponding to light label Dij; calculate the evaluation coefficient PXij of stage light in alternative schemes through formula PXij=γ×DPLij+θ×GKLij; take the stage light j corresponding to the maximum value of evaluation coefficient PXij as the operation scheme of atmosphere type i; match the lighting control parameters of stage light in the operation scheme based on the actual atmosphere type of the stage, and transmit the lighting control parameters to the terminal analysis module; the terminal control module controls the adjustable lamps based on the lighting control parameters; monitor the stage scene to complete the update of historical data.

[0058] For example, the alternative experimental scheme and the alternative actual scheme corresponding to the existing atmosphere label 3, γ=0.4, θ=0.6, the alternative experimental scheme and the alternative actual scheme are combined to obtain the alternative schemes of stage lighting D31 and stage lighting D32. The two sets of data are as follows:

[0059] Stage lighting D31: vote rate DPL31=35%, viewing rate GKL31=66.7%, the evaluation coefficient of stage D31 is calculated by the formula PX31=54.02; stage lighting D32: vote rate DPL32=45%, viewing rate GKL32=60%, the evaluation coefficient of stage D32 is calculated by the formula PX32=54; analysis shows that the evaluation coefficient of stage lighting D31 is greater than the evaluation coefficient of stage lighting D32, so stage lighting D31 is selected as the operation plan, the lighting parameters of stage lighting D31 are extracted, and the lighting parameters are transmitted to the terminal control module; the terminal control module controls the adjustable lamps based on the lighting parameters to present the effect of stage lighting D31.

[0060] Part of the data in the above formula is calculated by removing the dimension and taking its numerical value. The formula is a formula closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0061] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
