Large-space positioning calibration device and algorithm for fire extinguishing system

The invention discloses a large-space positioning calibration device and algorithm for a fire extinguishing system, and the device comprises a protection unit, the protection unit comprises a protection shell, the front surface of the protection shell is movably connected with a protection cover, and the lower end of the inner cavity of the protection shell is movably connected with a first stabilizing plate. The protective shell is used for protecting the core body, the first stabilizing plate is used for supporting the core body, a movable rod, a movable block and a first reset spring are matched for buffering and weakening impact force, and therefore the core body is protected, and a second reset spring and a second stabilizing plate are matched for buffering and weakening the impact force. The large-space positioning device for the fire fighting system is used for positioning the core body and buffering the impact force, so that the core body is prevented from being damaged, and the problems that the larg
