Fire extinguishing system and method of vertical-launched guidance fire extinguishing bomb

Abstract

The invention discloses a fire extinguishing system and method of a vertical-launched guidance fire extinguishing bomb. The system comprises a target locking and ground control station, a storage andvertical launching device, a guidance fire extinguishing bomb and a guidance communication link; the guidance fire extinguishing bomb is stored in the storage and vertical launching device; the guidance fire extinguishing bomb and the storage and vertical launching device are in wireless communication with the target locking and ground control station through the guidance communication link; and the target locking and ground control station is used for aiming at an ignition point, calculating the coordinate of the ignition point, sending the coordinate of the ignition point to the guidance fire extinguishing bomb through the guidance communication link and sending a launching instruction to the guidance fire extinguishing bomb and the storage and vertical launching device to control the guidance fire extinguishing bomb to fly to the ignition point. The system can meet the fire extinguishing demands of buildings above hundred meters, and has the characteristics of convenience to operate, lower cost and high automation degree.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a fire extinguishing system and method for launching guided fire bombs vertically. Background technique [0002] Fire is one of the main disasters faced by modern cities. As modern buildings are built higher and higher and denser, the danger of fire is also increasing. In recent years, the proportion of fires in my country has increased significantly, and the number of casualties and economic losses in high-rise building fire accidents have shown an obvious upward trend. The fire extinguishing of high-rise buildings, especially high-rise buildings above 100m, has always been a very difficult problem. Due to height and pressure restrictions, it is difficult for the fire ladder fire extinguishing system to reach a height of more than 100m. On the other hand, the number of fire-fighting helicopters in my country is limited and the cost is high, and it ...

AI Technical Summary

Problems solved by technology

Among them, the problems of UAVs equipped with rocket fire extinguishing bombs: 1. The load capacity of multi-rotor UAVs is limited, and the battery life is insufficient

2. Rocket fire extinguishing bombs are unguided

In the absence of a ballistic computer and launch tube attitude control, the launch is completely controlled by the ground operator, and the hit accuracy cannot be guaranteed

3. Ground remote control operation requires operators to have rich drone driving experience, which is not conducive to large-scale popularization and use

4. When the rocket fire extinguishing bomb explodes, the body fragments will cause secondary damage

Problems with loitering fire extinguishing bombs: 1. Complex structure and high cost

The high cost of a single fire extinguisher restricts mass use

2. Fixed-wing flight mode restricts the place of use

3. Flying to the target by means of TV remote control guidance requires the ground remote control personnel to have rich flying experience

4. Due to the high temperature of the flame, strong convection is formed near the ignition point, coupled with the strong high-altitude wind, the larger aerodynamic area will be seriously disturbed by the air flow, making the loitering fire extinguishing bomb suddenly deviate from the target at the moment of approaching the ignition point

[0005] Therefore, in general, the existing technologies generally have problems such as low accuracy of putting fire extinguishing agent, poor operability and economy, low degree of automation, and far from actual use.
