Abstract

The utility model relates to an electronic vane wheel type wind gauge, being composed of a gauge head and a host. The function of the gauge head part is to collect the signals of wind speed. When wind speed is measured, a vane wheel can be driven by wind to rotate around a shaft; when every blade of the vane wheel rotates, light ray which is emitted from a luminous tube to a receiving tube can be shielded for once, and the receiving tube can generate a pulse signal which can be sent to the host part through a conducting wire. The host part can convert the pulse signals which are inputted by the gauge part into a wind speed value, and the value can be displayed through a display. The device has the advantages of convenient detection, good anti-damp and anti-explosion performances, anti-interference to magnetic fields, and high measuring precision.

Description

Electronics wing wheel formula wind gage

The utility model relates to a kind of measurement instrument, particularly a kind of electronics wing wheel formula wind gage.

Anemometer table in the market, various wind table functions are simple, and measurement data just can obtain measuring wind after also need looking into figure or the form of tabling look-up calculating, uses very inconvenient.The present invention has designed a kind of electronics wing wheel formula wind gage for overcoming the problems referred to above, has easy to detectly, and protection against the tide and explosion-proof performance are good, and diamagnetic is disturbed the characteristics that measuring accuracy is high.

The purpose of this utility model provides a kind ofly stores electronics wing wheel formula wind gage with abstraction function to measured air speed value.

The utility model is achieved in that electronics wing wheel formula wind gage is to adopt gauge outfit and main frame two parts to constitute, the function of gauge outfit part is to gather wind velocity signal, when measuring wind, wind drives wing wheel and pivots, revolution is crossed a wing wheel blade, light by luminotron directive receiving tube is blocked once, and receiving tube will produce a pulse signal, and this pulse signal is sent into host machine part by lead.

When the light that sends when infrared luminotron is blocked by wing wheel, infrared receiving tube D ₂Be in high-impedance state, i.e. cut-off state, a point is a high level; When Infrared is passed the light hole direct irradiation at infrared receiving tube D ₂On, D ₂Be in low resistive state, i.e. conducting state, a point is a low level, wing wheel rotates continuously, D ₂Be in by, conducting transition status repeatedly, a point is in high-low level transition status repeatedly, promptly produces a series of pulses, and the pulse signal of a point generation is sent into host machine part after the IC2:C shaping.

The present invention adopts photoelectric tube to gather wind velocity signal, can prevent that external magnetic field from disturbing, and the pipe box of power valve and receiving tube has the protection receiving tube and not disturbed by veiling glare.Brace plays and makes the instrument head firmly be connected effect with main frame, with screw gauge outfit is fixed on the main frame.

Host machine part is the pulse signal that gauge outfit is partly imported, and converts thereof into air speed value, and shows by display.After gauge outfit part is input to host machine part with the wind velocity signal of gathering with impulse form, and the 89C51 single-chip microcomputer of host machine part is handled pulse signal, convert the per second mean wind speed to or the per minute mean wind speed directly shows with display.

The per minute mean wind speed calculates with following formula:

V in the formula ₁-per minute mean wind speed m/s

n ₁-per minute umber of pulse

-conversion coefficient

The per minute mean wind speed calculates with following formula:

V in the formula ₂-per second mean wind speed m/s,

n ₂-pulses per second

The following formula of definite employing of conversion coefficient:

V in the formula _Real-per minute actual average wind speed m/s,

n _Flat-average pulses per second

Surveying air speed data storage and abstraction function, is in the measuring wind speed process air speed value of required record to be stored successively, extracts record and for future reference in order to measuring the end back, has exempted the constraint of abominable measurement environment.

The utility model compared with prior art has easy to detectly, and protection against the tide and explosion-proof performance are good, and diamagnetic is disturbed the characteristics that measuring accuracy is high.

Concrete structure of the present utility model and embodiment are provided by the following drawings;

Fig. 1 is a general structure synoptic diagram of the present utility model;

Fig. 2 is the cross-sectional view of Fig. 1;

Fig. 3 is the circuit connection diagram of Fig. 1.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.

See Fig. 1,2, shown in 3: electronics wing wheel formula wind gage is to adopt gauge outfit and main frame two parts to constitute, gauge outfit partly is to have A-frame 3 on guide collar 2, on A-frame 3, connect wing wheel 1 by rotation axis, in gauge outfit, reception base 12 is housed respectively in the rear and front end of wing wheel by screw 4, and emission phototube 11, gauge outfit is fixed on the guide collar bearing 5 by screw 6, packing ring 16 is housed in guide type shoe 5, sensor plug-in unit 17 is housed below packing ring 16, guide type shoe 5 lower ends are fixed on the brace 15 by screw 13, brace 15 is fixed on the main frame by nut 18 by screw 14, motherboard 19 is housed in main frame, has front shell assemblies 7, on front shell assemblies 7, have button 8 at the front end of main frame, in the shell component 21 of back, have battery 10, on motherboard 19, have display board and 89C51 single-chip microcomputer.

Screw 9 fixed host computer plates 19, motherboard is fixed on the casing by screw 20 again.
