[0029] Initialize and adjust the speaker by the initialization adjustment unit: adjust the angle of the speaker until the working coverage area of ​​the speaker does not intersect with the warning area;

[0030] During subsequent activities held in the corresponding environment space, the dynamic control unit of the device can obtain the moving position of the person holding or wearing the microphone device in real time through the camera. When the corresponding person moves into the working coverage area of ​​the speaker, the speaker is rotated in real time until the corresponding person is no longer in the working coverage area of ​​the speaker.

[0031] A digital media data control management method comprises the following steps:

[0032] S1: Collect data of multimedia devices installed in the environment space and historical data of personnel activities in the space;

[0033] S2: Analyze the historical movement data of people in the space and divide the movement coverage area of ​​people;

[0034] S3: Analyze the intersection information between different mobile coverage areas and select the warning area based on the intersection information;

[0035] S4: Control and adjust the multimedia devices installed in the environment space.

[0036] Furthermore, in step S1: the positions of the speakers installed in the environmental space are collected, the longest coverage distance d of a randomly installed speaker is collected, and the working coverage area of ​​the corresponding speaker is confirmed to be a fan-shaped area with the speaker as the center and d as the radius, and real-time image data of the previous movement of people holding or wearing microphone devices in the environmental space is collected.

[0037] Further, in step S2: retrieve the real-time image data of the movement of a person holding or wearing a microphone device in the environment space during a previous random activity, establish a two-dimensional coordinate system with the center of the ground of the environment space as the origin, and obtain the moving point position coordinate set of a random person holding or wearing a microphone device during the corresponding activity as (E, F) = {(E1, F1), (E2, F2), ..., (E m , F m )}, where m represents the number of times a random person holding or wearing a microphone device moves during the corresponding activity. The straight-line distances between all moving points are calculated, and the straight-line distances are compared. The position coordinates of the two moving points with the longest straight-line distance are obtained respectively (E a ’ , F a ’ ) and (E b ’ , F b ’ ), divide the mobile coverage area covering all the moving points of a random person holding or wearing a microphone device into: is the center of the circle, The circular area with a radius of is used to divide the mobile coverage area of ​​all personnel in the corresponding activity process in the same way;

[0038] The purpose of collecting the previous movement data of different people through big data technology and dividing the mobile coverage area of ​​people holding or wearing microphone equipment is to analyze the range where people often stay in the corresponding place to better screen out the area that the speaker coverage area should avoid. The circular area is divided as the mobile coverage area with the midpoint of the two moving points with the longest straight-line distance as the center and the longest straight-line distance as the radius. The divided area can cover all the moving points of the people and reduce the division of redundant areas, which is conducive to improving the accuracy of subsequent speaker equipment regulation and reducing the difficulty of regulation.

[0039] Further, in step S3: the mobile coverage areas of different personnel are extracted one by one, and the number of mobile coverage areas of the remaining personnel that intersect with the extracted areas is obtained by counting as U = {U1, U2, ..., Un}, where n represents the number of mobile coverage areas, and the area set obtained in the remaining area that intersects with a randomly extracted mobile coverage area is s = {s1, s2, ..., s f}, calculate the early warning index P of a random mobile coverage area according to the following formula i :

[0040]

[0041] Among them, U i represents the number of areas in the mobile coverage area of ​​the remaining personnel that intersect with the i-th extracted area, f represents the number of areas in the remaining area that intersect with a random extracted mobile coverage area, s j represents the area of ​​intersection between the jth area in the remaining area and a randomly extracted mobile coverage area. The warning index set of n mobile coverage areas calculated in the same way is P = {P1, P2, ..., P i ,…,P n}, compare the warning indexes of different mobile coverage areas, arrange the coverage areas in descending order according to the warning index and divide them into v categories, where the warning index of each mobile coverage area in the former category is greater than that of the latter category, and obtain a random classification result. The set of average warning indexes of each mobile coverage area in v categories is W = {W1, W2, ..., W v}, calculate the discrete degree L of the warning index in a random classification result according to the following formula:

[0042]

[0043] Among them, W e Indicates the average value of the warning index of the e-th mobile coverage area in the v-th category in a random classification result. The discrete degree of the warning index in different classification results is calculated in the same way, and the classification result with the highest discrete degree is selected. From the selected classification results, the mobile coverage area in the first category is selected as the warning area;

[0044] By analyzing the number of intersections and intersection area data between different areas, the more the number of intersections with the extracted area and the larger the intersection area, the higher the probability that the corresponding venue will be in the corresponding area for speech or hosting activities, that is, the higher the warning index. The warning index of different mobile coverage areas is analyzed in combination with the above parameters, and the mobile coverage areas with high warning indexes are screened out by classification as warning areas that need to be avoided by the speaker working coverage area, thereby improving the accuracy of the screening results.

[0045] Further, in step S4: the speaker is initialized and adjusted: the angle of the speaker is adjusted until the working coverage area of ​​the speaker does not intersect with the area in the first category, and in the subsequent activities held in the corresponding environment space, real-time images are captured by the camera to obtain the moving position of the person holding or wearing the microphone device in real time, and when the corresponding person moves into the working coverage area of ​​the speaker, the speaker is controlled to rotate until the corresponding person is no longer in the working coverage area of ​​the speaker;

[0046] Firstly, by controlling the rotation of the speaker so that the working coverage range of the speaker avoids the warning area, the probability of a reduction in sound transmission gain due to the microphone entering the coverage range of the speaker can be reduced, while the probability of the need to continue to adjust the rotating speaker can be reduced, thereby reducing the workload of equipment control. Secondly, during the activity, the movement status of personnel is monitored in real time. When they move into the coverage range of the speaker, alarm information is fed back in real time based on communication technology, and the rotation of the speaker is controlled in time until the personnel is no longer within the working coverage range of the speaker, thereby reducing the probability of a reduction in sound transmission gain due to the microphone entering the coverage range of the speaker, which is conducive to the clear propagation of sound.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] The purpose of collecting the previous movement data of different people through big data technology and dividing the movement coverage area of ​​people holding or wearing microphone equipment is to analyze the range where people often stay in the corresponding place to better screen out the area that the speaker coverage area should avoid. The circular area is divided as the movement coverage area with the midpoint of the two moving points with the longest straight-line distance as the center and the longest straight-line distance as the radius. The divided area can not only cover all the moving points of the people, but also reduce the division of redundant areas, which is conducive to improving the accuracy of subsequent speaker equipment control and reducing the difficulty of control;

[0049] By analyzing the number of intersections and intersection areas between different areas, the early warning index of different mobile coverage areas is analyzed, and the mobile coverage areas with high early warning index are selected by classification as early warning areas that need to be avoided by the speaker working coverage area, thereby improving the accuracy of the screening results;

[0050] Firstly, by controlling the rotation of the speaker so that the working coverage range of the speaker avoids the warning area, the probability of a reduction in sound transmission gain due to the microphone entering the coverage range of the speaker can be reduced, while the probability of the need to continue to adjust the rotating speaker can be reduced, thereby reducing the workload of equipment control. Secondly, during the activity, the movement status of personnel is monitored in real time. When they move into the coverage range of the speaker, alarm information is fed back in real time based on communication technology, and the rotation of the speaker is controlled in time until the personnel is no longer within the working coverage range of the speaker, thereby reducing the probability of a reduction in sound transmission gain due to the microphone entering the coverage range of the speaker, which is conducive to the clear propagation of sound.
