While people are squeezing into cities and living in high-rise buildings, they are also facing more threats of disasters such as fires. At present, there are still many potential safety hazards in tall buildings. When a high-rise building encounters an emergency such as a fire, due to the limitations of time, space and many other factors, it often waits for rescuers to rescue, which means that the best time to escape is lost. Therefore, people's Self-rescue escape is a quicker and safer option. However, once a fire in a high-rise building blocks the stairs, it is like blocking people's lifeline, and the consequences of blindly jumping out of windows are even more disastrous. How to realize rapid escape is an urgent problem to be solved when the elevator is unusable and the stairs are blocked. the
