ABSTRACT:
A wind speed and wind direction signal generator includes first and second pulse signal generators each with a respective stator and rotor. The stator for each pulse generator has at least two stator coils mounted at a radial angle relative to each other in the direction of rotation of a rotor so that pulse signals excited on the stationary output lines of the two stator coils are phase shifted relative to each other at a phase detectable angle. The rotor has at least one permanent magnet with two poles spaced from each other for rotation relative to the respective stator coils and for exciting the pulse signals on the stator coil stationary output lines. First and second wind propellers are secured to the respective rotors and are oriented to compass directions at approximately 90.degree. defining a quadrant of a compass coordinate system. The wind propellers cause rotation of the respective rotors at respective frequencies proportional to first and second wind speed components. Phase detectors detect the direction of phase shift of pulse signals from each pair of stator coils from the first and second pulse signal generators. Counters count the pulses from the respective signals over predetermined time intervals generating wind speed component magnitude signals. A microprocessor and program elements compute the desired wind speed and wind direction information from the wind speed component magnitude signals, wind direction angle signals, quadrant signals, calibration factor signals, and trigonometric function signals.
