The invention discloses a transformer station inspection robot navigation method based on a laser track. The method comprises the steps: predesigning an inspection track which is formed by a linear track and a curve track, and arranging a target baffle plate for laser range finding; when the inspection robot walks along the linear track, controlling the inspection robot to walk along the linear track in a horizontal deflection angle, determining the inspection position through a laser range finder so as to monitor the transformer station equipment, and walking continuously after finishing monitoring of the inspection position; and when the offset for walking along the linear track is the length of the linear track, controlling the inspection robot to walk along the curve track in the horizontal deflection angle of the inspection robot, and continuously walking along the linear track after entering a new linear track. The transformer station inspection robot navigation method based on a laser track has the advantages of being simple in implementation, being high in stability, being low in cost, and being high in precision.
