The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] A comprehensive management method for stage equipment based on digital twins, the specific steps of the comprehensive management method are as follows:

[0030] By integrating BIM and IoT technology, high-precision 3D modeling is performed on each system module of the stage equipment. The system modules include lighting, sound, LED modules and stage machinery. A location is created based on BIM data and a 3D model is used to monitor the operating status of the module in real time. By monitoring voltage, current, temperature and leakage, and automatically alarming and gate control based on preset thresholds, the safety of the equipment is ensured. It can be understood that the stage equipment system architecture consists of multiple sub-modules, including lighting modules, sound modules, LED modules and stage machinery modules. Through BIM data and IoT technology, each module is integrated into a high-precision 3D model for real-time monitoring of equipment status.

[0031] The system supports full 3D scene interaction mode. By hiding the UI function, users can operate in a fully immersive 3D environment. The system provides multiple viewing modes, including fixed viewing, free viewing and roaming viewing, and supports 720-degree rotation, zooming, panning and overhead operations, allowing users to fully manage and monitor stage equipment from all angles. The system has a one-button control function to simplify the operation of sound and lighting management. Users can control music playback, light color adjustment, beam positioning and light intensity adjustment through one-button operation.

[0032] The system sets and monitors the electrical parameters of the equipment in the machine room, and can accurately monitor the electrical parameters of the individual power circuits of each module of the stage equipment. The system also has the early warning and alarm functions of the equipment in the machine room. When an abnormality is detected, the system will automatically switch to the corresponding 3D model display, using flashing early warnings to prompt the administrator to quickly locate and handle the fault. At the same time, it supports one-button closing or opening operations for easy inspection and maintenance.

[0033] It can be understood that the electrical parameter monitoring process is as follows:

[0034] Voltage, current and temperature monitoring formula:

[0035] V(t) represents the voltage at any time t.

[0036] I(t) represents the current at any time t.

[0037] T(t) represents the temperature at any time t

[0038] The corresponding alarm condition can be expressed as:

[0039]

[0040] If any of the above conditions are met, the system will trigger an alarm;

[0041] Specific real-time monitoring and intelligent early warning: The system uses digital micro-break sensors to monitor voltage, current, temperature and leakage in real time, and compares these data with preset thresholds. If an abnormality is detected, the system will automatically trigger an alarm and perform a tripping operation as needed to ensure the safe operation of the equipment.

[0042] The system analyzes the input current data of the audio module, constructs a current characteristic map, and determines the operating status of the audio system by identifying the deviation and fluctuation of the current value. The system compares the current characteristics with the preset threshold. If an abnormality is found, the faulty audio is marked as an abnormal device, and the fault location is displayed in the 3D model through a flashing prompt, so that the operation and maintenance personnel can conduct timely inspection and maintenance;

[0043] Deviation calculation of current characteristic spectrum:

[0044] I mean is the average current of the audio module,

[0045] I(t) is the actual current at any time t.

[0046] Deviation calculation formula:

[0047] ΔI(t)=I(t)-I mean

[0048] If |△I(t)|>threshold, it is judged as abnormal.

[0049] Specific audio module system management: Use the DMX plug-in and configure the DMX protocol and communication settings to control the standard protocol of stage lighting. Import the 3D model of the stage lighting equipment into the 3D scene, and configure the DMX address and channel information of the equipment in the DMX controller. The control signal is transmitted to each lighting device to achieve precise adjustment of brightness, color and beam direction;

[0050] The system conducts a comprehensive inspection of the lighting module, collects current and temperature rise data through sensors, and compares these data with the set thresholds to determine whether the operating status of the lamp is qualified. If an abnormality is detected, the system will automatically trigger the lamp maintenance or replacement procedure, and mark the fault location with a flashing prompt in the 3D model; multiple LED modules in the system constitute the LED module display area, and the system monitors the display area and sets the number of modules according to the actual usage scenario. The system collects input current in real time, constructs an operating characteristic map of the LED module, and determines whether there is an abnormality by comparing it with the preset threshold. If the values ​​are inconsistent, the system will indicate the fault location in yellow in the 3D model to guide the operation and maintenance personnel to perform maintenance and inspection;

[0051] Specific lighting module system management: control the sound system through MIDI plug-ins and configure the DMX protocol and communication setting protocol. Monitor MIDI signals and bind these signals to the parameters of the sound system (such as volume, tone, effects, etc.). When the platform receives a MIDI signal, the system will adjust the sound output in real time according to the signal value to ensure that the sound effect is synchronized with the performance requirements.

[0052] Specific LED module display system management: by installing and configuring the driver and related software of the large screen controller, ensure that the controller can correctly identify and operate the LED module. Confirm that the controller can exchange data with the digital twin platform through the Internet of Things (IoT) interface;

[0053] LED module display system abnormality judgment formula:

[0054] I LED (t) represents the LED module input current at any time t.

[0055] The preset threshold is

[0056] Abnormal judgment formula:

[0057] Abnormal judgment:

[0058] if If the allowable error is exceeded, the system will judge it as abnormal;

[0059] The system monitors the mechanical electric hoist boom in the stage mechanical module and has a load balancing function. The system collects the load-bearing capacity value of the electric hoist in real time through the pressure sensor, calculates the average value and sets it as the average value. The system selects the load-related equipment into the monitoring area, assigns it to the same operating channel, and performs load balancing through joystick operation. After the balancing is completed, if the load-bearing capacity of each electric hoist is consistent with the average value, the balancing is judged to be qualified; if not, the balancing will continue, and the position of the hanging point will be adjusted accordingly to ensure the stability and safety of the equipment operation.

[0060] Load balancing calculation:

[0061] F i represents the carrying capacity of the i-th electric hoist;

[0062] F avg is the average load-bearing capacity of all electric hoists;

[0063] Calculation of average bearing capacity:

[0064]

[0065] Balance conditions:

[0066] |F i -F avg |<Allowable error

[0067] If all |F i -F avg |If all are within the allowable error range, the balancing is successful;
