The invention discloses a remote control fire extinguishing method for high-rise buildings. The method comprises the following steps: an unmanned aerial vehicle loaded with a fire extinguishing bomb is controlled to fly to a high-rise building fire area; a shooting device on the unmanned aerial vehicle obtains images of the fire area in real time, and the images are transmitted to a control terminal; operators judge a fire source position according to the image information in the fire scene; according to the determined fire source position, the unmanned aerial vehicle is adjusted to fly to a proper bomb dropping position, and the bomb is dropped by aiming at the fire source position; and the fire extinguishing bomb throws a fire extinguishing agent by a preset time to finish fire extinguishing. The remote control fire extinguishing method for the high-rise buildings uses the unmanned aerial vehicle for carrying the fire extinguishing bomb to fly near the fire source to perform fire extinguishing, has such characteristics as short acting distance and short time, and can finish fire extinguishing of the high-rise buildings at initial stage of the fire.
