A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal,
A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device is an opto electric measuring device with at least two light paths. Each of the at least two light paths has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind. The light-emitting elements determine the angle position of the element aligning with the direction of the wind.

1. A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device comprising an opto electric measuring device with at least two light paths, each of which has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind, the at least one screen and the light path configuration corresponding to the position of the element aligning with the direction of the wind can be swivelled relative to each other around the axis of the screen, and an electronic control and analysis unit is provided that individually activates the light-emitting elements during a measuring or analysis phase and hereby determines the angle position of the element aligning with the direction of the wind. 2. The weather station as claimed in claim 1, wherein the markings are openings or slits in the screen. 3. The weather station as claimed in claim 1, wherein the screen is an orifice plate. 4. The weather station as claimed in claim 1, wherein the light-emitting elements are light-emitting diodes. 5. The weather station as claimed in claim 1, wherein the light sensor is a photo diode or a photo transistor. 6. The weather station as claimed in claim 1, wherein the element aligning with the direction of the wind is a wind vane. 7. The weather station as claimed in claim 1, wherein the element aligning with the direction of the wind is fastened to a shaft, which is mounted on bearings in the housing or rack and on which the at least one screen is located. 8. The weather station as claimed in claim 1, wherein the electronic analysis and control unit activates the light-emitting elements at predetermined time intervals, at least once in each time interval during a measuring phase. 9. The weather station as claimed in claim 1, wherein the electronic analysis and control unit activates the light-emitting elements non-simultaneously during the measuring phase. 10. The weather station as claimed in claim 1, wherein the light-emitting elements are activated during each measuring phase at least once with a different frequency. 11. The weather station as claimed in claim 1, wherein when the screen is a disc or plate with several groups of optically scannable markings located on concentric circles on the axis of the disc or plate, the light-emitting elements are arranged in sequence radially to the axis of the plate. 12. The weather station as claimed in claim 1, wherein when the screen is a cylinder with several groups of optically scannable markings that are offset in relation to each other in the direction of the cylinder axis, the light-emitting elements are offset in relation to each other axially to the axis of the screen. 13. The weather station as claimed in claim 1, wherein the light sensor is located on a light guide, which forms several light inlet areas, of which at least one is allocated to each light-emitting element. 14. The weather station as claimed in claim 13, wherein the light guide or the light inlet areas of this light guide are located on a line parallel to the arrangement of the light-emitting elements. 15. The weather station as claimed in claim 1, wherein a device for measuring the wind force with a wind wheel driven in a rotary manner by the wind that works together with a sensor for generating an electric signal corresponding to the wind force, whereby the wind wheel is a freely revolving impeller wheel. 16. The weather station as claimed in claim 15, wherein the at leas t one sensor for generating the signal corresponding to the wind force is an inductive sensor.
