However, in the rapid development of high-rise buildings, there are a number of safety problems, and fire safety is one of the key problems that people pay attention to. Due to the high building, once a fire disaster occurs, the siphon effect can rapidly expand the disaster condition, and the difficulty of people evacuation is high. Therefore, the research of the fire extinguishing technology of the high-rise building has important practical significance.

At present, the main problems of high-rise building fires are: 1. fire control is difficult, the fire extinguishing height is limited, the external fire extinguishing effect is poor, and internal attack can not be implemented; 2. the power deployment is difficult, the space is small, the arrival power is large, the coordination is difficult, and the site is easy to be disordered. The common high-altitude fire extinguishing method mainly uses pipelines arranged on the arm frame of the elevating fire truck to extinguish high-rise fire. However, the common fire-fighting spray head cannot continuously work near a fire scene due to the fact that the spray head is not high-temperature-resistant, and the spray head cannot be flexibly aimed at the root of a fire source for spraying, so that the fire-extinguishing efficiency is low. For example, patent CN201320448921.5 discloses a multi-folding arm elevating fire truck, which can continuously fight for a long time, but has poor flexibility, complex operation and low efficiency of finding the root of a fire source; for example, the CN201320448921.5 patent realizes that the composite fire extinguishing agent is sprayed out at the same time in high altitude, which not only plays a role in quick, effective and anti-reburning fire extinguishing effect on high altitude fire, but also can save the fire extinguishing agent consumption, greatly reduce the fire extinguishing cost, effectively solve the problems of difficult and low efficiency of high altitude fire extinguishing, and the commander lacks effective information and can not make effective judgment on fire conditions, so that the commander can not make the most reasonable force deployment.
