Abstract
The invention relates to wind speed and direction measurement technology, and aims to provide an anemoclinograph wind meter with high precision, good stability and low cost. The anemoclinograph wind meter comprises a wind measuring head and a signal processing device, wherein the wind measuring head consists of a shell, pull pressure sensors and a support bar; a horizontal circular section in the hollow shell is distributed with three pull pressure sensors with the same specification, which are symmetrically distributed at an interval of 120 degrees around a center of a circle; one end of each pull pressure sensor is fixed on the inner wall of the shell, while the other end is fixed on the support bar; the shell is not contacted with the support bar; wind pressure born by the shell is gathered on the support bar through the sensors, so the resultant force of the pull pressure of the sensors corresponds to the wind pressure; and the pressure direction indicates the wind direction, and the pressure and the wind speed have a certain functional relation which depends on the shape and size of the shell and can be calculated through a fluid mechanics theory or obtained through wind tunnel tests. The anemoclinograph wind meter can be used for wind generating systems, and also can be applied to the fields such as meteorology, transportation and the like.
Description
Technical field the present invention relates to a kind of wind speed and direction measuring technique.
Background technology
Wind speed and direction measuring technique application is very extensive: as at meteorological field, for the monitoring of typhoon provides accurate data; In the civil aviaton field, for takeoff and landing provide reliable wind speed and direction reference; In the highway bridge construction, for its design and construction provides foundation; At new energy field, especially in the good wind power generation field of development prospect, survey the wind technology and have important effect.
In wind power generation field, the survey wind devices that is most widely used is the wind measuring system that vane and weathervane are formed, and the subject matter that faces is that the mechanical type rotary part is easy to wear, and freezing, obstruction, fracture etc. may take place when weather changes; At present, ultrasonic survey wind technology has been subjected to paying close attention to widely and deep research with its very high precision and noncontact characteristics, and domestic premium quality product still is in conceptual phase, external complicated ultrasonic anemometer precision height, but cost an arm and a leg.
Summary of the invention
The purpose of this invention is to provide that a kind of precision is higher, good stability, with low cost, can be widely used in the wind speed and direction measuring instrument in fields such as wind-power electricity generation, meteorology, traffic, construction.
To achieve these goals, anemoclinograph provided by the invention comprises and surveys public attention, signal processing apparatus that wherein survey public attention and be made of housing, pull pressure sensor, support component, support component contains support bar and securing member.The hollow shell horizontal section is circular, is distributed with three pull pressure sensor on the circular section, becomes 120 ° of symmetrical distributions around the center of circle, and sensor one end is fixed on the inner walls, and the other end is fixed on the support bar.Housing does not have directly with support bar and contacts, it is pressure in wind, is called for short wind pressure, converges on the support bar by three sensors, sensor balances each other to the acting force of housing and the wind pressure to housing, so making a concerted effort of three pressures that sensor is experienced is corresponding with wind pressure.The direction indication wind direction of wind pressure, the size of wind pressure becomes certain functional relation with wind speed, and it is decided by the hull shape size, can be calculated or be obtained by the wind tunnel test demarcation by Hydrodynamics Theory.Sensor is converted to electric signal with pressure, in signal processing apparatus it is nursed one's health and calculates, and obtains wind speed and direction.
Above-mentioned housing, horizontal section are circular, and the windward side is identical during with the assurance change of the wind; Certain rigid is arranged, when being subjected to the pressure of wind deformation very little, guaranteed measuring accuracy.
Above-mentioned pull pressure sensor, the direction that must satisfy foil gauge institute's induction force in operate as normal during installation is a horizontal direction; Three sensor specifications are identical, and their center lines are positioned on the same surface level, and extended line intersects on the housing axis a bit, 120 ° each other of angles, the distribution of one-tenth Y type.
Wind pressure that housing is subjected to and wind speed and direction have a certain functional relation, making a concerted effort of the pressure that three pull pressure sensor are shared is identical with the suffered wind pressure equal and opposite in direction direction of housing, therefore measure the pressure signal of three sensors, obtain three pulling force or pressure on same surface level about the 120 ° of symmetries in axis, by the simple mechanics-based synthesis analysis, just can obtain size and direction with joint efforts, obtain the indicator signal of wind speed and direction according to the vector summation of three direction component.
Signal processing apparatus comprises modulate circuit and computing module.By modulate circuit the electric signal of sensor output is nursed one's health; In computing module, according to the corresponding relation of electric signal-pressure, pressure-wind pressure and wind pressure-wind speed and direction, design operational method, three road electric signal are reduced in succession component, wind pressure, the wind speed and direction of three directions.
Surveying public attention among the present invention is the special construction that housing and pull pressure sensor are formed, and has corresponding relation between wind speed and direction and the wind pressure in this structure, calculates wind speed and direction in view of the above.The present invention is simple in structure, and method is reliable, can satisfy that precision is higher, good stability, requirement with low cost.
