In an emergency, clear and rapid evacuation instructions are the key to ensuring life safety. Traditional two-dimensional evacuation diagrams have limited viewing angles and cannot intuitively show the relationship between complex three-dimensional spaces. The volumetric emergency evacuation guide uses three-dimensional modeling technology to three-dimensionally visualize the building structure, evacuation paths and key facilities. This greatly improves the efficiency and accuracy of information transmission and is an important tool in modern building safety management.
Why Volumetric Emergency Evacuation Guidelines Are Needed
In multi-story buildings, traditional evacuation signs and floor plans often make it difficult for people to quickly locate their location and the best escape direction. This is also true in underground spaces and in venues with complex structures. The volumetric guide is presented in a three-dimensional form, which is like a scaled-down digital model of the building. Users can rotate it 360 degrees and perform zoom operations to understand the spatial layout from any angle. This intuitiveness is particularly important in panic environments, as it can help personnel quickly establish spatial awareness, thereby reducing decision-making time.
For places such as shopping malls, transportation hubs, and large factories, volumetric evacuation systems can integrate real-time data. For example, once a sensor detects a fire somewhere or a blocked passage, the corresponding path in the three-dimensional model will dynamically turn red, or be marked as unavailable, and the system will automatically calculate and highlight a new safe evacuation route. This kind of dynamic adjustment ability is simply impossible to achieve with static floor plans. It upgrades evacuation guidance from "fixed script" to "intelligent navigation."
What core information does the volumetric evacuation guide contain?
An effective guide that can be used for volumetric evacuation must first include an accurate building structure model. This model covers all floors, stairs, elevator shafts, corridors, room divisions, and load-bearing walls. This information is the basis for path planning. Secondly, the locations of all safety exits, fire escapes, and evacuation stairs must be clearly marked, and eye-catching colors or light strips must be used to display recommended evacuation routes. In addition, the location of emergency facilities such as fire extinguishers, emergency facilities such as fire hydrants, emergency facilities such as alarms, emergency lighting, and first aid kits all need to be accurately marked in the model.
In addition to static facilities, the intelligent system will integrate a dynamic information layer, which includes real-time personnel heat maps that can display the degree of crowding in different areas, as well as hazard source markers, such as fire points, smoke diffusion ranges, hazardous material leakage areas, and safety zone indicators, such as designated refuge floors and outdoor assembly points. The superposition of these multiple layers of information gives commanders and evacuees a comprehensive situational awareness.
How to create a volumetric emergency evacuation guide
The first step in production is to obtain accurate building data. For newly built buildings, the BIM (Building Information Model) data in the design stage can be directly used. For existing buildings, it is necessary to use 3D laser scanning or oblique photogrammetry to carry out real-life modeling to ensure the accuracy of the model. Global procurement services for weak current intelligent products are provided, which includes high-precision 3D scanning equipment and modeling software to lay a solid foundation for the project.
After the data is obtained, the information must be annotated and the system developed on a professional 3D platform. This includes dividing fire zones, planning evacuation routes, marking facility locations, and developing user interaction interfaces. For large-scale projects, it is generally necessary to connect data with the fire protection system and building automation system to achieve alarm linkage. The final product can be deployed on a variety of terminals such as touch screens, mobile apps, and AR glasses, ensuring that offline backup is still available for access in extreme situations such as power outages.
How volumetric guidance can be used in actual evacuation
On a daily basis, Volume Guides are excellent training and practice tools. Managers can use it to simulate various disaster scenarios and plan evacuation strategies for different locations. New employees or visitors can use interactive models to quickly familiarize themselves with the environment and remember the locations of key exits. During regular drills, the system can guide different "personnel" to evacuate from their respective starting points to test the rationality and bottlenecks of the plan.
When a real alarm sounds, touch screens deployed in public areas or mobile devices in the hands of employees will automatically activate evacuation mode. Its interface will highlight the "you are here" positioning point, and use flashing arrows or light flow to indicate the most appropriate escape direction at the moment. For the on-site command center, the system will provide an overall bird's-eye view, which can monitor the movement of personnel and the spread of danger in real time, thereby facilitating precise command and dispatch, such as using broadcasts to guide people to avoid congested areas or dangerous areas.
What technical challenges do volumetric evacuation systems face?
The most important challenges are data accuracy and updating and maintenance. If the internal structure of the building undergoes modifications, the model must be updated simultaneously, otherwise it will be misleading. To achieve this, a standardized asset management process needs to be established. The second is the accuracy of positioning. Especially when the indoor GPS signal fails, Wi-Fi, Bluetooth beacons or visual positioning technology must be used to achieve meter-level or even sub-meter level positioning, which has higher requirements for infrastructure deployment and algorithms.
Another challenge lies in the robustness of the system. Under extreme conditions such as fires, power outages, and network interruptions, the system must have the ability to degrade. For example, the local terminal caches key model data, relies on the built-in battery to perform work, or uses a low-power electronic ink screen to display static evacuation maps. At the same time, the system interface design must be extremely concise to prevent information overload or operational confusion in emergency situations. Colors, icons, and animations must follow emergency design specifications.
What is the development trend of volumetric evacuation guidance in the future?
The trend in the future is to be highly integrated and intelligent. The system will also be deeply integrated with the Internet of Things. Every smoke sensor, access control and camera will become a data node, and a digital twin emergency system will be built. Artificial intelligence will be used to predict the path of smoke spreading, conduct in-depth analysis of crowd behavior patterns, dynamically generate the best diversion plan, and even command emergency robots to take the lead in exploring the path.
A more natural interaction method is brought by augmented reality, that is, AR technology. With the help of mobile phones or AR glasses, evacuees can directly see the virtual direction arrows and exit signs superimposed on the real corridor in their field of vision, achieving "what you see is what you are guided". In addition, personalized evacuation will become possible. The system will provide the safest path customized based on the user's identity and real-time location, effectively achieving a leap from "popular guidance" to "personalized escort."
In the office building you are in or the public places you frequent, is the traditional floor evacuation plan currently used or a more advanced electronic guidance system? Do you think the biggest obstacle to implementing volumetric emergency evacuation guidelines will be cost, technology or people’s cognitive habits?
