According to an embodiment of the present invention, a fan radius and a central angle may be determined based on a range of the fire area, wherein the fan radius is less than or equal to a maximum spraying distance of the fire extinguishing agent sprayed by the fire fighting assembly of the respective fire fighting robot. Further, it is also possible to determine a central angle, for example, if the area of the fire area is small, the plurality of fire robots may enclose the fire area, i.e., the central angle is 360 °, the sector is circular, and for example, the fire area is at the wall side, the plurality of fire robots may enclose the fire area halfway, i.e., the central angle is 180 ° or slightly less than 180 °, and for example, the fire area is at the wall corner, the plurality of fire robots may enclose the fire area halfway, i.e., the central angle is 90 ° or slightly less than 90 °. In another example, if the area of the fire area is large, a plurality of fire robots cannot surround the fire area (i.e., even if the fire robots surround the fire area, the radius of the circle formed by the surrounding is larger than the maximum spraying distance of the fire extinguishing agent sprayed from the fire extinguishing assembly, and the fire extinguishing agent cannot cover the entire fire area), in this case, a plurality of portions of the fire area may be semi-surrounded a plurality of times, and each time of the semi-surrounded, a central angle may be set, for example, to 90 ° and the fire extinguishing agent sprayed extinguishes a flame in a portion of the fire area, and then another portion of the fire area may be semi-surrounded again, and the above-described process may be performed a plurality of times until the flame in the fire area is all extinguished. The invention does not limit the specific setting mode of the sector radius and the central angle.

The position of each fire-fighting robot in the fan-shaped formation can be rapidly determined by keeping the coordinate system unchanged, each fire-fighting robot can be rapidly moved to the position of each fire-fighting robot in the fan-shaped formation, and after fire extinguishing is finished, the fire-fighting robots can be rapidly restored to the positions of the fire-fighting robots in the preset formation, without waiting for the end of the movement of the pilot fire-fighting robots, the positions of the fire-fighting robots can be adjusted after the coordinate system is changed, the efficiency of forming the fire-fighting formation and the efficiency of restoring the preset formation can be improved, and the fire-extinguishing efficiency can be improved.
