Embodiment
Below in conjunction with accompanying drawing, the embodiment of the utility model wind direction autotracker is elaborated.Accompanying drawing only schematically shows structure and the annexation of the utility model wind direction tracking device, does not represent the practical structures of the utility model wind direction tracking device.
Referring to Fig. 1, the utility model wind direction tracking device comprises controller 1, comparator 2, DC stepper motor 3 and two wind pressure sensors 4.
All described wind pressure sensors 4 are positioned at same plane, make the benchmark of two wind pressure sensor 4 measuring wind identical, so that two wind pressure sensors 4 compare wind speed, can be because the position difference of wind pressure sensor 4 causes the measurement of wind pressure sensor 4 inaccurate.Described wind pressure sensor 4 is existing wind pressure sensor, and the internal structure at this to wind pressure sensor does not repeat.In the time of the normal parallel of wind speed and described wind pressure sensor 4 place planes, the output of described two wind pressure sensors 4 is identical, in the time that the normal of described wind speed and described wind pressure sensor 4 place planes is not parallel, and the output difference of described wind pressure sensor 4.The output terminal of described wind pressure sensor 4 is connected with the positive-negative input end of described comparator 2 respectively, in order to voltage signal is passed to described comparator 2.
The output terminal of described comparator 2 is connected with the input end of described controller 1.Described comparator 2 is existing conventional comparator, is not repeated herein.Described comparator 2 is for the voltage signal of described wind pressure sensor 4 receiving is compared, and comparative result is transferred to described controller 1.In the time of the normal parallel of wind speed and described wind pressure sensor 4 place planes, the output of described two wind pressure sensors 4 is identical, and comparator 2 is output as 0; When described wind speed is when not parallel with the normal of described wind pressure sensor 4 place planes, the output difference of described wind pressure sensor 4, comparator 2 is output as both differences.Output rusults is inputted described controller 1 by described comparator 2.
Further, described comparator 2 is connected with described controller 1 by an AD converter 5, and described AD converter 5 is carried out analog-to-digital conversion.Described AD converter 5 is existing conventional AD converter 5, is not repeated herein.
