However, the law and energy of fire cannot be fully mastered by human, and fire is often caused by various reasons in human life and work. Since ancient times, fires have produced indelible, devastating attacks on human material and property and mental beliefs.
In a high-rise forest city, the human being still cannot use electricity as another natural energy, so that the frequency of fire outburst caused by electric energy in the city is high. In addition, in cities full of heat island effect, various combustibles can be easily ignited by hot sunlight in high-temperature weather under the action of lenses of various glass products. Various causes sometimes occur in the case of fire in an unmanned environment.
In modern civilization, people have gradually learned how to avoid the occurrence of fire and how to quickly rescue after disasters. For example, a fire alarm is installed on the ceiling of a floor, when smoke is generated, the fire alarm immediately gives an alarm and informs a background server, and the background server informs rescue workers to start for rescue. When the slightly advanced fire alarm senses smoke, the fire-fighting nozzle is opened and sprays water, so that the fire is suppressed temporarily.
However, these fire alarm devices have serious defects, such as the specific position of the fire cannot be accurately positioned, only the alarm is carried out simply, when a fire is sent on one floor, the generated smoke can trigger the fire alarm devices on the similar floors at the same time, and the rescuers cannot accurately position which floor to which floor the fire occurs. When a fire breaks out in a room, the ordinary fire alarm cannot judge which direction the fire breaks out, and which direction the fire does not break out and is suitable for the intrusion of rescue workers. The existence of these problems leads to the constant bottleneck of fire rescue.
