Abstract
PURPOSE:To accurately measure the distribution, etc., of the deposited sand and earth in a pond by providing an X-axial accelerometer and a Y-axial accelerometer on a stable rack, mounting them on a moving body together with an ultrasonic sounding machine, and converting accelerometer output into position data by a signal conversion part. CONSTITUTION:The moving body 1 is guided to a specific position in the pond 4 under the control of a propulsion machine 17. Then the Y-axial accelerometer 3 is set in the meridian azimuth, the X-axial accelerometer 2 is arranged at right angles to it, and a reference position is set in the pond 14. When the moving body 1 which is guided by the propulsion machine 17 moves on the water surface in a direction having a certain angle to the meridian azimuth, acceleration data are generated by the X-axial accelerometer 2 and Y-axial accelerometer 3 during the movement as to the two orthogonal directions of latitude and longitude. Those acceleration data are integrated by two integrators 7 in the signal conversion part 6 and an X-axial output circuit 8 and a Y-axial output circuit 9 obtain position data based upon the reference position in the directions of the latitude and longitude. A display device 12 displays the X-axial and Y-axial position data and the deposition level at the position.
