FIELD: location finding. ^ SUBSTANCE: according to the method module and angle of increment vectors of motion are determined which vectors relate to motion of transportation vehicle. Then correspondent position of transportation vehicle is determined automatically at specified points within specific area when the transportation vehicle passes those points. Current position of transportation vehicle within area is found by means of vector addition of increment vectors of motion with vector of position of current position. Automatical finding of the position of transportation vehicle is performed by means of pick-up unit mounted on transportation vehicle which unit interacts with corresponding control mark without having contact with it. Control mark has reflecting and non-reflecting surfaces which are subject to scanning simultaneously by means of two signals sent from transportation vehicle. Coordinates of control position of transportation vehicle and angle of movement are determined due to estimation of reflected signals depending on time. ^ EFFECT: improved precision; improved reliability. ^ 13 cl, 5 dwg |
