The multimedia exhibition hall control system is redefining the interactive logic of the exhibition display industry as an "intelligent hub". From the historical corridor of museums to the technology exhibition halls of enterprises, from the planning sand table of smart cities to the immersive theater of cultural and tourism scenic spots, this system integrates multiple elements such as lighting, sound, imaging, and interactive devices to build a perceptible, interactive, and evolving intelligent ecological space.

1、 Technical architecture: Modular design supports full scene coverage

The modern multimedia exhibition hall control system adopts a hybrid architecture of "central host partition controller", with core equipment including a central processor that supports multi protocol access, programmable logic controller (PLC), environmental sensor array, and wireless touch terminal. Taking the Xunwei OY-6000P model as an example, it has 8 built-in RS232/485 interfaces, 4 infrared emission ports, and a gigabit network module, which can simultaneously control projection matrices, LED splicing screens, intelligent lighting systems, and environmental temperature control equipment. The system supports network protocols such as TCP/IP, HTTP, MQTT, etc., and achieves seamless control across floors and exhibition areas through 5G/Wi Fi 6. A single host can scale up to 256 control nodes.

At the software level, the system adopts a layered architecture design:

Data layer: Integrate audience behavior analysis models, generate real-time exhibition attention reports through algorithms such as heatmap tracking and dwell time statistics.

Control layer: supports no code programming, users can customize scene linkage logic through a drag and drop interface, such as setting "automatically turn on explanatory lighting and play 3D animation when the audience approaches the display cabinet".

Application layer: Provides a mobile management app that supports remote device monitoring, fault warning, content updates, and other functions. Management personnel can view key indicators such as projector bulb life and air conditioning operation status in real time.

2、 Core Function: From Device Control to Space Intelligence

Scenario based linkage control
The system can preset multiple display modes and achieve synchronous adjustment of lighting, sound effects, and images through one click switching. For example, in the "Space Exploration" exhibition area of the science museum, when the audience triggers the interactive device, the system automatically dims the ambient light, starts star projection, plays rocket launch sound effects, and pushes the commentary content to the audience's mobile phone. After the introduction of a visual central control system in Yunnan Unicom's smart exhibition hall, management personnel can synchronously control devices such as LED screens, sliding doors, and smart curtains through tablets, achieving dynamic reconstruction of the exhibition hall space.

Intelligent Content Management
Support unified scheduling of multi format media files such as 4K/8K videos, PPTs, 3D models, etc., and can set strategies such as timed playback, loop playback, and conditional triggered playback. The IoT operation and maintenance platform of DeYun IoT goes further by analyzing the audience's stay time through AI algorithms and automatically optimizing the playback order of exhibition items. If the average viewing time of a certain video is lower than the set threshold, the system will lower its playback priority.

Environmental adaptive regulation
Integrated temperature and humidity sensors, lighting sensors, and human body sensing modules, the system can automatically adjust equipment parameters according to environmental changes. For example, in the cultural relics exhibition area of a museum, when the humidity exceeds the standard, the system automatically starts the dehumidifier and turns off the fresh air system; During the nighttime closure period, energy-saving control of "lights on when people come and lights off when people leave" is achieved through infrared sensing.

Data driven decision-making
The system backend can generate multidimensional data reports, including device runtime, failure rate statistics, audience behavior paths, etc. The application case of the Construction Bank exhibition hall shows that by analyzing the hotspots of visitors' stay in the fintech exhibition area, the management optimized the layout of exhibition items, resulting in a 37% increase in the exposure rate of core products.

3、 Industry Applications: From Traditional Exhibition Halls to Emerging Scenarios

cultural venues
The "Digital Cultural Relics Library" exhibition hall of the Palace Museum adopts a central control system linked with holographic projection and AR guidance. Visitors can view the 3D demonstration of the cultural relic restoration process through gesture recognition. The system is also linked with the fire protection system. When the smoke sensor triggers an alarm, all electronic devices are automatically turned off and emergency lighting is activated.

Corporate Exhibition Hall
The exhibition hall of Huawei Songshan Lake Base has deployed a central control system of edge computing that supports 5G MEC to achieve interactive control of millisecond response. In the "Intelligent Factory" sand table exhibition area, the system synchronously schedules the robotic arm model, data big screen, and environmental sound effects, realistically reproducing the production line operation scene.

cultural and tourism industry
Shanghai Disneyland's "Dream of Light Phantom Show" coordinates over 2000 lighting devices, 8 sets of large projectors, and 15 sound arrays through a central control system to create an immersive light and shadow show covering the entire castle. The system automatically adjusts the performance plan based on weather data - enhancing ground projection brightness on rainy days and optimizing laser penetration effect on foggy days.

Smart City
The central control system of Shenzhen Urban Planning Museum is connected to the urban big data platform to retrieve real-time information such as traffic, weather, and population. In the "Future Cities" exhibition area, visitors can select different time points through the touch screen, and the system immediately generates corresponding city models and links them to play relevant policy interpretation videos.
