Platform Development Engine: Adopt Unity or Unreal Engine. Unity has strong cross-platform capabilities and a relatively short development cycle, suitable for rapid iterative development; Unreal Engine excels in graphics rendering and can create realistic visual effects, suitable for scenarios with extremely high graphic quality requirements.
Positioning Technology:
Personnel Positioning: Adopt UWB (Ultra-Wideband) positioning technology with high precision, enabling high-accuracy indoor and outdoor positioning. Equip personnel with positioning tags to obtain real-time location information.
Vehicle Positioning: Combine GPS and Bluetooth positioning technologies. Install positioning devices on vehicles to meet outdoor driving positioning needs while achieving accurate indoor positioning to ensure accurate vehicle location tracking.
Data Collection and Transmission:
Use sensors to collect real-time equipment data, fire alarm data, etc., and transmit data to the platform through industrial Ethernet, wireless sensor networks (WSN), and other methods.
Adopt MQTT protocol for data transmission, which is lightweight and low-power, suitable for ensuring data real-time and stability in the complex network environment of chemical plants.
Database: Select InfluxDB to store time-series data such as equipment operating parameters, which performs excellently in processing time-series data; use MySQL to store structured data such as personnel information, vehicle information, and basic equipment information, facilitating data management and querying.
Visualization Framework: Introduce visualization frameworks such as Echarts to display four-color maps, real-time equipment data charts, etc., enhancing data visualization effects.
4. Data Collection and Processing
| Factory Model Data | Obtain detailed information such as factory buildings and equipment layout through field measurements, factory CAD drawings, and other methods, and import into 3D modeling software to build accurate 3D models. |
| Real-Time Equipment Data | Install sensors on key equipment to collect parameters such as temperature, pressure, and flow rate in real-time. After data cleaning and preprocessing, store in InfluxDB database and transmit to the 3D platform for real-time display. |
| Personnel and Vehicle Location Data | Bluetooth, GPS, UWB, and other positioning devices collect real-time location information of personnel and vehicles. After coordinate conversion and data processing, update location display in the 3D scene in real-time. |

| Risk Assessment Data | Comprehensively consider factors such as equipment operating status, hazardous substance storage volume, and personnel activities to conduct risk assessment calculations, generate risk zones and four-color map data, and display on the platform. |
5. Three-Dimensional Scene Construction Process
Factory Model Creation:
Using 3D modeling software, create models of factory buildings, equipment, roads, etc., according to the actual layout and dimensions of the factory, ensuring the accuracy and detail of the models.
Process materials and lighting effects for the models to make them closer to real scenes and enhance visual effects.
Risk Zoning and Four-Color Map Drawing:
Based on risk assessment data, divide different areas into risk levels in the 3D scene and differentiate them with different colors or identifiers.
Generate a four-color map based on risk zoning data, overlay it on the 3D scene, and intuitively display the overall risk distribution of the factory.
Electronic Fence Setup: In the 3D scene, draw electronic fence areas for dangerous areas (such as chemical storage areas, high-voltage equipment areas, etc.), set intrusion trigger rules and alarm mechanisms.
Real-Time Equipment Data Display: Associate equipment models with real-time data, and dynamically display equipment operating parameters on equipment models in the form of numbers, charts, etc.
Personnel and Vehicle Positioning Implementation: Connect personnel and vehicle positioning data to the 3D platform. Through coordinate mapping, display their positions in real-time in the 3D scene, and set trajectory display functions to facilitate viewing of movement paths.
Camera Position Interaction Setup: Add camera models in the 3D scene and establish connections with actual camera equipment. When clicking on camera models, obtain and display real-time surveillance footage through the video stream server.
Fire Alarm and Emergency Early Warning Integration: Interface the fire alarm system and emergency early warning system with the 3D platform. When receiving alarm or early warning signals, display the alarm location and early warning information in a prominent manner (such as flashing red lights, pop-up prompts, etc.) in the 3D scene, and issue sound alarms.
6. System Testing and Optimization
Functional Testing: Conduct comprehensive testing of functions such as factory risk zoning, four-color map display, real-time equipment data display, electronic fence alarm, personnel positioning, vehicle positioning, camera position interaction, fire alarm, and emergency early warning to ensure all functions operate normally and data is accurate.
