The invention discloses a sound beacon signal extraction method and system based on a dislocation superposition algorithm. The method comprises steps that a sound beacon signal acquisition system is established; a superposition start point is randomly selected for an acquired original signal; length of each interception signal segment is determined according to an adjacent period or same time interval superimposition mode; linear superposition for each interception signal segment is carried out to realize sound beacon signal extraction; an algorithm writing program is introduced into a single-chip microcomputer, and establishment of a sound beacon signal extraction system is accomplished. The method is advantaged in that sound beacon signals extracted through employing the dislocation superposition algorithm require no time frequency conversion, the method is convenient and simple, and extracted signal waveform has high accuracy.
