Abstract
The utility model provides a breeze velocity meter, relating to the technical field of wind speed measuring instruments. The velocity meter comprises a support (1), a bearing (2), a shaft (3), wind cups (4), a code disc (5), an optical coupler (6) and a main circuit (7); the bearing (2) is inlayed on up and down two ends of the support (1); the shaft (3) is inserted in the bearing (2); the wind cups (4) and the code disc are fixed on the shaft (3); a light through hole of the code disc (5) is located on an optical path of the optical coupler (6) while the code disc (5) is in rotation; the optical coupler (6) is in connection with the main circuit (7). Under the wind effect, the rotation of the wind cups drives the code disc for rotation, the code disc rotates in the optical coupler and generates pulse signals which are inputted to the main circuit, and wind speed values are displayed on an LED (Light Emitting Diode) display after the pulse signals are processed by the main circuit. The breeze velocity meter has high sensitivity, high resolution, small errors and low electricity consumption and is safe and convenient for use.
Description
Technical field
The utility model relates to the measuring wind speed Instrument technology field, is specifically related to a kind of gentle breeze velocity metre, and it can be applied in the various occasions that need the gentle breeze amount.
Background technology
At present, the instrument kind that is used for measuring wind is a lot: have mechanically, mechanical electronic mode is also arranged; Be useful on the directed wind of surveying, also be useful on the meteorological wind of surveying; Have and adopt worm screw to carry out transmission, also have and adopt gear to carry out transmission.For an anemometer, the index of weighing its performance mainly contains range, starts wind speed and nonlinearity erron etc.Vane formula anemometer is a kind of in the anemometer, and it is to calculate actual wind speed through the rotating speed that vane forms in wind.Existing vane formula anemometer complex structure, sensitivity is low, and air speed error is big, and reading is inconvenient.
The utility model content
In order to solve existing anemometer complex structure, sensitivity is low, air speed error is big, reading is inconvenient problem, the utility model provides a kind of novel gentle breeze velocity metre.
The technical scheme that the utility model technical solution problem is taked is following:
The gentle breeze velocity metre comprises support, bearing, axle, vane, code-disc, optocoupler and main circuit, and said bearing is embedded in the two ends up and down of support; Axle is inserted in the bearing; Vane and code-disc are fixed on the axle, and the light hole of code-disc is positioned on the light path of optocoupler when rotated, and optocoupler links to each other with main circuit.
Above-mentioned main circuit comprises single-chip microcomputer and light-emitting diode display; The number of above-mentioned vane is three; Above-mentioned bearing is a jewel bearing.
The gentle breeze velocity metre of the utility model is under the effect of wind-force; Vane rotating band moving axis rotates under the support of bearing, and the code-disc that is fixed on the axle rotates in optocoupler, produces pulse signal; Handle through main circuit, directly in light-emitting diode display, read gentle breeze speed numerical value.
The beneficial effect of the utility model is: volume is little, and is simple in structure, and vane rotates flexibly, and is highly sensitive, and resolution is high, and error is little, and power consumption is little, and is safe and convenient to use.
