Abstract

The present invention belongs to the technical field of efficient fragmentation of hard rocks. Provided are a vehicle-mounted system and method for controlling high-energy laser-induced rock fracturing, the method comprising: by means of a second image acquisition and analysis unit, acquiring surrounding environment information of an electric flat car during movement; on the basis of a stored motion path of the electric flat car and the surrounding environment information, an electric flat car control unit generating a first control instruction; the electric flat car controlling the electric flat car to move to a designated position for rock fragmentation; by means of a first image acquisition and analysis unit, acquiring the type of a rock to be fragmented, and after a laser emission unit is started, acquiring real-time condition information of laser-induced rock fracturing; a laser control unit acquiring a laser emission parameter corresponding to the type of the current rock to be fragmented, and upon receiving the real-time condition information of laser-induced rock fracturing that is acquired by the first image acquisition and analysis unit, adjusting the laser emission parameter, and generating a second control instruction on the basis of the laser emission parameter; and the laser emission unit controlling the laser emission unit to start emitting a laser for rock fragmentation.
