Description

Technical Field

[0001] This utility model relates to the field of digital stage technology, and in particular to a digital stage multi-terminal collaborative monitoring system. Background Technology

[0002] The stage manager is the core command center of modern performance activities, responsible for real-time coordination of lighting, sound, mechanical equipment, actor scheduling, and other aspects to ensure the precise execution of the performance process. The stage manager needs to monitor multiple independent subsystems and coordinate the operations of each department through voice communication or commands.

[0003] However, existing stage management systems have significant flaws, specifically: 1) Data silos: Lighting, sound, mechanical control, etc. belong to independent systems, using independent hardware and closed architecture. The data formats are incompatible with each other, which makes it impossible to share key information across systems. It relies on manual comparison of data from multiple terminals for coordination and response.

[0004] 2) Response delay: Emergency situations on stage (such as actors shifting their positions or equipment malfunctions) rely on supervisors to visually identify them or passively receive fault alarms, resulting in delayed emergency response.

[0005] 3) Complex operation: Supervisors need to operate multiple control terminals simultaneously during the performance, frequently switch between operating interfaces and execute redundant commands, which not only reduces the response speed, but also easily causes a chain of failures due to operational errors, resulting in low efficiency.

[0030] In this embodiment, the stage equipment sensor 23 includes a temperature sensor and a current sensor integrated into the lighting equipment for monitoring the temperature and operating current of the lighting fixtures; a vibration sensor installed in the sound equipment for detecting the amplitude of the loudspeakers; and an encoder and a torque sensor installed on the mechanical device for collecting motion position and load parameters. The actor tracking module 24 includes a UWB (Ultra-Wideband Wireless Communication) tag, a positioning base station, and an infrared camera for real-time tracking of the actor's precise position and movement trajectory. Specifically, the UWB tag is connected to the positioning base station via ultra-wideband wireless communication technology and communicates with the positioning base station via the UWB protocol to track the actor's precise position in real time. The positioning base station is connected to a 5G edge gateway via a 5G private network and to the central processing unit 3 via the 5G edge gateway 51.

They continuously collect key data on the actors' skeletal structure and transmit it to the AI ​​analysis engine of the central processing unit 3 via the RTSP protocol for motion trajectory modeling. The environmental monitoring module 25 includes a lidar, microphone array, temperature sensor, humidity sensor, smoke sensor, and light sensor. The lidar can scan for obstacles in the stage space, the microphone array can capture abnormal sounds, and the temperature, humidity, smoke, and light sensors can monitor stage environmental parameters and trigger abnormal alarms using existing early warning technologies (such as fire warnings and insufficient visibility alerts). Specifically, the environmental monitoring module 25 is connected to the environmental sensor gateway 54 via LoRa or Zigbee wireless protocols, synchronously transmitting data to the environmental sensor gateway 54, and then connecting to the central processing unit 3 via the 5G edge gateway 51.

[0031] The stage equipment sensor 23, the actor tracking module 24's positioning base station, and the environmental monitoring module 25 are all connected to the central processing unit 3 via the 5G edge gateway 51. Infrared camera data from the actor tracking module 24 is transmitted to the central processing unit 3 via the core switch 13. Specifically, the stage equipment sensor 23 is connected to the industrial protocol gateway 53 via an RS-485 twisted-pair cable. After Modbus RTU-to-TCP conversion, it is connected to the Ethernet port of the 5G edge gateway 51 via a CAT6A network cable, and transmitted to the AI ​​analysis engine via the 5G private network. It interacts with the digital twin platform 32 via a RESTful API or Apache Kafka message queue. Equipment operating status data is pushed via the Apache Kafka message queue, and emergency commands are invoked via the RESTful API. The environmental monitoring module 25 is first connected to the environmental sensor gateway via the LoRa / Zigbee wireless protocol, and then connected to the central processing unit 3 via the 5G edge gateway.

[0032] The data acquisition unit is used to collect real-time data on the operating status of stage equipment, actor positions, and environmental parameters, providing a multimodal data source for subsequent AI analysis and digital twin platforms.

[0033] Specifically, the central processing unit 3 integrates an AI analysis engine and a digital twin platform. In this embodiment, the AI ​​analysis engine 31 is configured with an existing LSTM time series analysis model (such as a model built into the Keras library) and receives stage equipment current, temperature, position parameters, and actor position trajectory data transmitted by the data acquisition unit 2 via gigabit Ethernet or a 5G private network. The AI ​​analysis engine 31 is also configured with an existing predictive maintenance algorithm module (such as an anomaly detection model from the scikit-learn library) and an existing security strategy module (such as the obstacle avoidance algorithm package from ROS), and transmits the generated equipment status signals and control commands to the digital twin platform and the terminal collaboration unit 4 via a RESTful API and an Apache Kafka message queue.

[0034] The central processing unit 3 is connected to the core switch 13 via a CAT6 network cable to transmit equipment status data; the digital twin platform communicates with the industrial Ethernet switch 52 via the OPC UA protocol, and its communication interface module converts the instruction data of the AI ​​analysis engine into Modbus-RTU protocol format for transmission, sending control commands to the stage equipment controller 6; the three-dimensional data output end of the digital twin platform establishes a wireless connection with the AR supervision terminal 41 of the multi-terminal collaboration unit 4 via the 5G edge gateway 51, and is simultaneously connected to the receiver controller of the LED large screen display system 44 via the gigabit Ethernet interface of the video processor 12.

[0035] Among them, the stage equipment controller 6 is the control object of the central processing unit 3 and the multi-terminal collaboration unit 4, including lighting controller, sound controller and mechanical device controller, etc.

[0036] Specifically, the multi-terminal collaborative unit 4 includes an AR monitoring terminal 41, a mobile control terminal 42, an emergency broadcast terminal 43, and an LED large screen display system 44 (including a server).

[0037] In this embodiment, the AR supervision terminal 41 includes AR glasses hardware (Hololens 2), which establishes a physical connection with the digital twin platform 32 through the 5G edge gateway 51. The director uses the AR glasses to receive the real-time stage video stream transmitted by the video processor 12, and synchronizes the data with the UWB positioning tag in the actor tracking module 24 through the 5G edge gateway 51. The device status information (such as light angle and robotic arm position) and the actor's movement trajectory are superimposed on the optical display module of the AR glasses.

[0038] The mobile control terminal 42 uses a tablet computer (such as an iPad Pro) as its hardware carrier and carries a control APP, serving as the core device for operation interface and command output. The mobile control terminal 42 connects to the stage equipment controller 6 via 4G / 5G cellular network + Bluetooth 5.2 and links with the emergency broadcast terminal 43 via the MQTT protocol. It is used by directors or technicians to remotely adjust equipment parameters (such as light color temperature and robotic arm speed), supports hierarchical control authority (director authority > technician authority > actor authority) for managing control rights, and features a high-brightness interface identifying the main control terminal. The hierarchical access control is existing technology.

[0039] The emergency broadcast terminal 43 includes sound-generating components such as directional acoustic speakers and a stage sound reinforcement system. The emergency broadcast terminal 43 is connected to the AI ​​analysis engine via single-mode fiber optic cable, powered by the core switch 13, and integrated with the stage sound reinforcement system via PoE power supply and a digital audio bus. It is used to broadcast voice commands (such as pausing performances or guiding evacuation) in emergency situations. The directional acoustic speakers send warning commands to specific areas, and AI voice synthesis generates standardized emergency scripts. The emergency broadcast terminal 43 also links with the AR monitoring terminal 41 to mark escape routes and with the mobile control terminal 42 to forcibly lock dangerous equipment. The AI ​​voice synthesis is a current technology.

[0040] The server of the LED large screen display system 44 is connected to the LED display screen via a CAT6 network cable to adjust brightness and color parameters; it is also connected to the video processor 12 via a CAT6 network cable to receive H.265 encoded video signals; and it is connected to the digital twin platform via the 5G edge gateway 51 to display a three-dimensional stage twin interface and realize global visual monitoring.

[0041] The multi-terminal collaboration unit is used to coordinate the operation instructions and feedback of AR monitoring terminals, mobile control terminals and emergency broadcast terminals through a unified protocol and real-time communication network, so as to ensure data synchronization and execution consistency of multiple terminals.

[0042] Specifically, the communication unit 5 includes a 5G edge gateway 51, an industrial Ethernet switch 52, an industrial protocol gateway 53, and an environmental sensor gateway 54.

[0043] Communication unit 5 also includes 5G private network and industrial Ethernet protocol.

[0044] The 5G private network 51 is deployed inside the stage and is connected to the central processing unit 3 through the MEC edge computing node (NVIDIA EGX) deployed on the side of the stage; it establishes a wireless connection with the stage equipment controller 6 through the 3.5GHz band (n78 band); it is used to carry the real-time video stream (>200Mbps bandwidth) of the AR supervision terminal 41, the low-latency instructions (<10ms end-to-end latency) of the mobile control terminal 42, and supports the priority preemption transmission (highest QoS level) of the emergency broadcast terminal 43 to ensure that emergency instructions are distributed without congestion.

[0045] The Industrial Ethernet protocol establishes a physical connection with the stage equipment controller (including lighting controller, sound controller, and mechanical device controller) through the RJ45 port of the Industrial Ethernet Switch 52. The devices communicate with each other using the Modbus-TCP protocol and the OPCUA protocol to transmit real-time status data of the stage equipment (such as light brightness values ​​and robotic arm coordinates). It supports millisecond-level data polling and abnormal alarm threshold settings (such as temperature over-limit triggering shutdown). It connects to the stage equipment sensors and polls the equipment data every 100ms.

[0046] The OPC UA protocol connects with the digital twin platform 32 and third-party systems (such as ticketing systems and fire protection systems) through a unified data proxy gateway, enabling seamless integration of device data with the AI ​​analysis engine 31, and supporting historical data archiving and security auditing.

[0047] The communication unit is used to build a high-bandwidth, low-latency transmission channel, supports multi-protocol compatibility and redundant link design, and ensures real-time data synchronization and reliable distribution of emergency instructions among stage equipment, multiple terminals and central processing unit.

[0048] In this embodiment, the working principle is as follows: The data acquisition unit collects stage audio and video, equipment operating parameters, actor position trajectories, and environmental data in real time through high-definition PTZ cameras, stage equipment sensors, actor tracking modules, and environmental monitoring modules. This data is transmitted to the core switch via CAT6 network cables. The AI ​​analysis engine of the central processing unit analyzes the data, predicts equipment anomalies, and identifies actor boundary violations through configuration models. The digital twin platform displays a 3D stage twin interface, enabling global visual monitoring. The multi-terminal collaboration unit (AR supervision terminal, mobile control terminal, and emergency broadcast terminal) receives instructions from the central processing unit, enabling AR visual supervision, remote equipment control, and emergency command broadcasting, respectively. Simultaneously, data from each terminal is synchronized through a unified protocol to ensure consistency. Finally, the equipment execution results are transmitted back to the central processing unit via the communication unit, updating the 3D stage twin interface.

[0049] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
