PURPOSE:To enable transmission of an exact position of a steel plate cell at all times by detecting the light from a lamp signal attached freely vertically movably to the steel plate cell and displaying the position of the steel plate cell by computer processing. CONSTITUTION:A lamp signal 7 is attached to a cell 1 via freely vertically movable float 6 by guide rollers 9-11 which contact with the respective faces of a joint 5 extending in the vertical direction of a steel plate cell 1 to be carried by a crane boat to a driving position and to be driven by a driving machine. The light from the signal 7 held in the specified position on the water surface is detected with image measuring devices 12-15, by which the position signal of the cell 1 is formed. The position of the cell 1 is displayed by the computer processing of the position signal. The exact position of the steel plate cell is thus transmitted at all times to the operator for driving the steel plate cell and the driving of the steel plate cell is accomplished quickly with high accuracy. |
