Description

The three-dimensional velocity instrument

Technical field

The utility model relates to automatic measurement instrument field, specifically a kind of three-dimensional velocity instrument.

Background technology

Measuring wind speed has important effect at aspects such as daily life, fish production and other fields, and for example: the fisherman needs accurately direction and the size of judgement wind when going fishing on the sea.And at present, traditional anemoscope on the market generally only rests on two-dimentional level, while surveying wind speed, need to just meet facing the wind to the size that could measure exactly wind, but the people is when measuring wind, generally with feeling to be difficult to accurately judge wind direction, this will cause the data of measuring to be inaccurate, sometimes or even wrong, and, generally also can only measure the size of wind, do not determine the direction of wind, so just limited it and applied more widely.Although some accurate anemoscopes are also arranged on market, such as three-dimensional velocity instrument based on the velocity of ultrasonic sound sensing etc., because they involve great expense, have also limited their widespread use.

Summary of the invention

For the above-mentioned deficiency of prior art, it is a kind of cheap, highly sensitive and can measure the three-dimensional velocity instrument of size and directions that the utility model provides, and its volume is small and exquisite, easy to carry, easy to use.

A kind of three-dimensional velocity instrument, comprise harvester and display device, and described harvester comprises base, is arranged on the three-dimensional orthogonal support on base, and each termination of three-dimensional orthogonal support is equipped with motor, on the rotor of motor, fan blade is installed; Described display device comprise successively connect cross zero balancing and D/A converter module, single chip control module, LCD MODULE, motor by wire with zero balancing and D/A converter module are connected excessively.

Three-dimensional velocity instrument as above, the LCD MODULE below also is provided with shift knob and reset button.

Three-dimensional velocity instrument as above, the battery that described display device also comprises with zero balancing and D/A converter module, single chip control module, LCD MODULE are connected excessively.

The utility model volume is small and exquisite, is convenient for carrying, cheap, the many dimensions of the result recorded than common anemoscope, thereby big or small result is also more accurate, and can mean direction.

Embodiment

Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is clearly and completely described.

Refer to Fig. 1, the utility model three-dimensional velocity instrument comprises harvester and display device 5, described harvester comprises base 1, is arranged on the three-dimensional orthogonal support 2 on base 1, described three-dimensional orthogonal support comprises the first support of vertical installation and the second support and the 3rd support of vertical the first support, and the second support and the 3rd support are orthogonal and in the same plane.Each termination of three-dimensional orthogonal support 2 is equipped with motor 4, and fan blade 3 is installed on the rotor of motor 4.

Please further with reference to figure 2, described display device 5 comprise connect successively cross zero balancing and D/A converter module 8, single chip control module 9, LCD MODULE 10, motor 4 is connected with mistake zero balancing and D/A converter module 8 by wire 6.

Every group of motor 4 and fan blade 3 obtain the voltage that the one-component of wind vector produces, and three groups of voltages mean three wind speed components, and three groups of wind speed components are synthetic must the three-dimensional velocity vector.Be three voltages that component produces that three motors 4 fixing on the utility model three-dimensional orthogonal support 2 are surveyed respectively the space wind speed decomposed along three orthogonal directions X, Y, Z; the positive and negative direction with the wind speed component of voltage is corresponding, and the size of voltage is corresponding with the size of wind speed component; Cross three groups of voltages that zero balancing and analog-to-digital conversion module 8 utilize motor 4 to gather and do respective handling and obtain three groups of digital signals, the wind speed of three groups of digital signals and three different dimensions is corresponding respectively; Single chip control module 9 will be crossed three groups of number digital signals that zero balancing and D/A converter module 8 pass over and do respective handling, result be passed to LCD MODULE 10 and be shown.LCD MODULE 10 shows the information such as the size, rank, direction of three-dimensional velocity vectors, and wherein, direction is three groups of angles with XYZ tri-quadrature holder orientation.As shown in Figure 4, its demonstration be the schematic diagram of wind vector, arrow length means the wind speed size, α, β, γ are respectively the angle of wind vector and three quadrature wind direction XYZ.Three-dimensional orthogonal support 2 coincide with the orientation in life, can determine wind direction by habits and customs, such as: mean southeaster, size is 3 grades.

Through evidence, the material object that the utility model is made shows, can mean the wind speed of whole mentality of designing, and size, rank, direction all can correctly show.

LCD MODULE 10 belows also can arrange shift knob 12 and reset button 13, for the unlatching of controlling LCD MODULE 10 with reset.The battery 11 that described display device 5 also can comprise with zero balancing and D/A converter module 8, single chip control module 9, LCD MODULE 10 are connected excessively, crossing zero balancing and D/A converter module 8, single chip control module 9, LCD MODULE 10 and battery 11 is arranged in box body (as shown in Figure 3), LCD MODULE 10 is arranged on the outside surface of box body, compact conformation, is easy to carry.

The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly belong to those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
