Abstract
The present invention relates to a wind direction informing device composed by a wind direction indicating device and a wind direction displaying circuit, wherein the wind direction indicating device includes a wind vane, a chassis and a small shaft. One end of the wind vane shows an arrow shape and the other end of the wind vane shows a wing shape, and the underpart of the arrow-shaped end contains a small magnet, wherein the small magnet is connected with the arrow-shaped end; and the underpart of the chassis contains eight Hall elements evenly arranged on the circumference of the chassis in eight directions, i.e., east, west, south, north, northeast, southeast, northwest and southwest. According to the operating principle of the Hall element, it is known that once the Hall element contacts with a magnetic field, the Hall element can output a voltage, so that when the small magnet on the wind vane contacts any one of the Hall elements in any direction, the Hall element in that direction outputs a voltage, wherein the voltage enables the corresponding light emitting diode to illuminate through the displaying circuit, and thereby the wind direction can be determined by merely observing the orientation of the luminous LED indoors.

Summary of the invention
The purpose of this invention is to provide a kind of wind direction informer, this wind direction informer is promptly known wind direction indoor according to showing, for reaching above-mentioned purpose, the present invention solves technical scheme that its technical matters adopts: form a wind direction informer by a wind direction indicating device and a wind direction display circuit, in described wind direction indicating device, contain a weathervane, one is used for a chassis that claims weathervane, and little axle, one end of described weathervane is arrow shaped, the other end is the wing shape, the described below that is a sagittate end is contained a small magnet and is linked together therewith, the centre position of described weathervane is occupied an aperture and is contained on the described little axle, cooperation between described aperture and the described little axle is movingly, be that weathervane can freely rotate along little axle, it also is the arrow of weathervane can rotate and point to wind under the blowing of wind-force direction, the rounded shape in described chassis, described chassis home position is equipped with a described little axle and claims weathervane by little, 8 Hall elements are contained in the below on described chassis, be arranged on 8 directions of chassis circumference branches such as described Hall element, described direction is meant east, the west, south, north, northeast, the southeast, the northwest, 8 directions in southwest, the position of described 8 direction Hall elements and the small magnet on the weathervane align one by one, according to the principle of work of Hall element as can be known, promptly can output voltage as long as Hall element touches magnetic field, the Hall element that also is small magnet on the weathervane which direction of Hall element of touching which direction promptly can output voltage, therefore the wind that has voltage output promptly to know to blow which direction according to the Hall element of which direction, for example, the Hall element of northeastward has voltage output promptly to know to have scraped northeaster.
Contain 8 Hall elements in the described wind direction display circuit, promptly be arranged in 8 Hall elements on the chassis, also contain 8 voltage comparators, 8 light emitting diodes that are used to show 8 directions, 8 current-limiting resistances, and two resistance that are used for dividing potential drop, the positive pole of described 8 Hall elements connects power supply, minus earth, its output terminal is connected with the normal phase input end of 8 voltage comparators respectively, and the inverting input of 8 voltage comparators is connected on the junction of two divider resistances, and two divider resistances are serially connected between power supply and the ground, described two effects that are used for divider resistance provide reference voltage for 8 voltage comparators, the positive pole of described 8 light emitting diodes is connected with the output terminal of 8 voltage comparators respectively through current-limiting resistance separately, its minus earth, in described 8 light emitting diodes: the light emitting diode that shows the east wind direction be arranged in east to Hall element corresponding, the light emitting diode that shows the west wind direction be arranged in the west to Hall element corresponding, the rest may be inferred for other light emitting diode and Hall element corresponding relation.
Working method of the present invention is: weathervane can point to certain direction under wind blows, and the small magnet of weathervane below can touch chassis certain Hall element of below and make its output voltage, this voltage makes certain voltage comparator counter-rotating and makes its output high level, this high level makes certain light emitting diode shinny, therefore according to shinny direction position, light emitting diode place, promptly know and blowed the wind of certain direction, for example shinny direction position, light emitting diode place is a northeastward, has both known and has scraped northeaster.
Advantage of the present invention is: need not arrive the field observation weathervane and determine wind direction, and can determine wind direction at indoor observation light emitting diode.
