Abstract
A wind measuring system can be used in meterology for a more accurate and reliable measurement of the velocity and the direction of an air current. The system has a sensor for velocity and a wind vane with sensors for horizontal and vertical wind directions. Depending on the velocity of the air current, a reference disc is rotated which generates pulses for each revolution. Horizontal air direction pressure is transmitted to bearing axles and a gear to cause rotational motion of a transducer for horizontal direction. Vertical air direction pressure rotates a transducer for vertical direction. The phase difference of the pulses from the transducers produces time delays which are recorded by a unit for electronic processing of the information. An output is generated indicating wind speed and direction.

A wind measuring system comprising
- a velocity sensor, a horizontal direction sensor and a vertical direction sensor;
- said velocity sensor comprising a reference disk and a first stationary optical sensor, said reference disk being mechanically driven to rotate in a first direction by a velocity component of the wind, said first optical sensor sensing the speed of rotation of said reference disk in said first direction;
- said horizontal direction sensor comprising a second optical sensor movable relative to said reference disk, movement of said second optical sensor being mechanically driven in a direction parallel to said first direction by a horizontal direction component of the wind, said second optical sensor sensing a position relative to said first optical sensor by reference to said reference disk;
- said vertical direction sensor comprising a third optical sensor movable relative to said reference disk, movement of said third optical sensor being mechanically driven in a direction parallel to said first direction by a vertical direction component of the wind, said third optical sensor sensing a position relative to said first optical sensor by reference to said reference disk;
- and
- circuit means for calculating wind velocity and horizontal and vertical wind direction based respectively on the speed of rotation of the reference disk and the positions of the second and third sensors relative to the first sensor.
A wind measuring system comprising
- a first inner housing mounted for rotation about a vertical axis and a second outer housing mounted for rotation about both a horizontal and a vertical axis;
- a velocity sensor, a horizontal direction sensor and a vertical direction sensor;
- said velocity sensor comprising wind resisting means attached to a rotating axle, whereby movement of wind causes said axle to rotate;
- said axle being mounted for free rotation in said first housing;
- velocity measurement means coacting with said axle whereby wind velocity is determined from speed of rotation of said axle, said velocity measurement means comprising an optical sensor mounted stationary relative to said axle;
- said horizontal and vertical direction sensors comprising a wind vane fixedly mounted to said second housing, whereby horizontal movement of wind causes said second housing to rotate about said vertical axis and vertical movement of wind causes said second housing to rotate about said horizontal axis;
- horizontal direction measurement means coacting with said velocity measurement means whereby horizontal wind direction is determined from the relative position of the horizontal direction measurement means relative to the velocity measurement means, said horizontal direction measurement means comprising an optical sensor movable relative to said velocity measurement means by horizontal movement of said horizontal direction sensor;
- vertical direction measurement means coacting with said velocity measurement means whereby vertical wind direction is determined from the relative position of the vertical direction measurement means relative to the velocity measurement means, said vertical direction measurement means comprising an optical sensor movable relative to said velocity measurement means by vertical movement of said vertical direction sensor.
