Custom-designed wireless sensors, artificial intelligence (A.I.) enhanced surveillance cameras, intelligent emergency signage systems, and edge computing servers are used to sample fire and crowd data, operate the intelligent evacuation algorithm, and guide the crowd with the signage system in real-time conditions. This algorithm combines cellular automata with the potential energy field (PEF) model in fluid dynamic theory (FDT) to choose safe paths for the crowd and reduce the possibility of stampedes. This study proposes a real-time building evacuation model with an improved cellular automata (CA) method. The future emergency guidance system should be more intelligent and be able to guide people to evacuate with a higher survival possibility. Following a planned route may lead the crowd to move towards dangers, such as smoke and fire. However, these guidances are sometimes insufficient or misleading, particularly for evacuating from high-rise buildings or complex buildings, such as schools, hospitals, and stadiums.
Most of the buildings today use pre-installed signages to guide the emergence evacuation. The coordinate value of cell 1 is (6.5,7.5), and the coordinate value of the cell farthest from the exit is (15.5,0.5), then:įacility emergence evacuation is often a complicated process under extreme conditions. The exit is the closest exit to cell 1, and the coordinates of the exit are (0,8). Continue to calculate other parameters as follows: (a) Calculation of the priority value Taking cell 1 as an example, the coordinate value takes the value of the center point of the square, and the unit is the number of squares. B is very strange to the evacuation environment, and the value of is 1, so there is no commonly used exit, and panic will appear during the emergency evacuation process. When an emergency occurs, it is relatively calm, and the value of is 3. The value of is 4 and the exit is often used. Suppose A is familiar with the evacuation environment. The numbers 1 to 8 are the neighborhood of A, and the numbers 5 and 8 to 14 are the neighborhood of B. A and B in the box are the subjects of this study. People are represented by circles, and their distribution in the figure shows the distribution of people in the initial space. The size is about 4 cells, that is, the width is 2m. Example analysis diagram As shown in the figure 8, a rectangular two-dimensional space of 16 * 16 is set as the evacuation area, which includes the evacuation exit on the left and the exit above, as shown in the red border in the figure.
