[0050] Wherein, the plurality of refers to three or more than three.

[0051] It can be understood that the sampling main body can be a whole, and the plurality of air inlets are distributed on the sampling main body to save cost; wherein, two air inlets can define an air duct; it can also be that two or more air inlets define a channel, that is, two or more air inlets are connected to an air duct.

[0058] It can be understood that the sampling layer 21 can be one, two or more than two; the setting of multiple sampling layers 21 is beneficial to expand the air inlet range, so that the wind in each direction can be measured, thereby improving the measurement accuracy and reducing the measurement requirement. The air inlet 22 is also an air outlet, and the wind duct 23 is formed between two air inlets located in different directions, and the wind flows into the wind duct 23 from one air inlet and flows out from the other air inlet.

[0061] The centers of the air inlets 22 located in the same sampling layer 21 are at the same height position in the preset direction, that is, the center lines of the air inlets 22 of the same sampling layer 21 are at the same aspect, which is beneficial to measure the wind power data in each direction while avoiding the influence of the height difference between the air inlets 22 on the accuracy of the wind power data.

[0062] In some embodiments, as shown in Figure 3 Each sampling layer 21 can be arranged side by side with two air inlets 22 in the same direction, which is beneficial to expand the air inlet area while ensuring the wind speed, so that the wind can flow reliably inside the air duct 23.

[0063] It can also be understood that the first temperature detection assembly 30 is arranged inside the air duct 23, and is used to collect temperature information of at least two different positions in the extension direction of the air duct 23, which can be two different temperatures, four different temperatures, six different temperatures, etc., thereby being beneficial to improve the detection accuracy.

[0066] The wind direction and wind speed measuring device 100 of the embodiment of the present application solves the problems of high measurement cost and low measurement accuracy of the existing wind speed meter.

The first temperature detection assembly 30 is arranged in each air duct 23, and the first temperature detection assembly 30 is used for collecting temperature information at at least two different positions along the extension direction of the air duct 23. The collected temperature information data is beneficial to improving the measurement accuracy. The second temperature detection assembly 50 and the humidity detection assembly 60 are arranged in or outside the air duct 23, and are used for collecting the ambient temperature and humidity. The controller 40 is used for determining the heat carried away by the wind according to the temperature information collected by the first temperature detection assembly 30, and indirectly determining the wind direction and wind speed in combination with the temperature and humidity collected by the second temperature detection assembly 50 and the humidity detection assembly 60. The sampling main body of the wind direction and wind speed measuring device has a plurality of air inlets 22, the plurality of air inlets 22 are distributed in different directions and are communicated with at least two different air ducts 23, the wind in each direction can be measured, 360° omnidirectional wind speed and wind direction measurement is realized, the use is not limited, the measurement range is wide, the reliability is high, the maintenance is easy, and the temperature detection is performed by measuring the temperature at different positions in the air duct. The wind power data is determined by the temperature, which is beneficial to improving the detection accuracy.

[0067] In the preferred embodiment, the sampling main body 20 includes at least two sampling layers 21, the at least two sampling layers 21 are arranged in parallel along the preset direction, and the positions of the air inlets of the adjacent two sampling layers 21 along the preset direction are staggered with each other, so that the projection areas of the air ducts 23 of the adjacent two sampling layers 21 on the mounting surface partially overlap or completely stagger, for the wind in each direction to enter the air duct 23 from the air inlet, and the air inlet range is increased.

[0068] The first temperature detection assemblies 30 in the air ducts 23 of the adjacent two sampling layers 21 are uniformly distributed in the projection interval on the mounting surface, for detecting the temperature at different positions and improving the detection accuracy.

[0069] The sampling layers 21 can be two or more than two, and are arranged in a staggered manner along the direction perpendicular to the mounting surface of the base 10. The air inlets 22 of the adjacent two sampling layers 21 are staggered with each other, which is beneficial to measure the wind in each direction, increase the measurement range, and improve the detection accuracy.

[0070] For example, the sampling body 20 is in a cylindrical shape, and the side surface of the cylindrical shape is in a circular arc shape, which is beneficial to expand the air inlet range and reduce the wind resistance. The sampling layer 21 includes a first sampling layer 211 and a second sampling layer 212 arranged along the height direction of the cylindrical sampling body 20.

The sampling layer 21 can also be four or more than four, which is determined according to the size of the sampling body and the actual detection accuracy requirement.

[0072] As an implementable way, each air duct 23 of each sampling layer 21 is curved into an arc-shaped air duct 23 towards the center direction of the sampling body 20. The curvatures of different parts of the arc-shaped air duct 23 are different, so that the wind resistance inside the arc-shaped air duct 23 is reduced.

[0073] The arc-shaped air duct 23 of the embodiment conforms to the principle of fluid dynamics, ensures reliable flow of the wind with minimum wind resistance, and is beneficial to improve the measurement accuracy and save space, and is beneficial to increase the number of air ducts 23.

[0074] In some embodiments, the diameter of the air inlet 22 gradually decreases along the direction from the side surface of the sampling body 20 to the center of the sampling body 20. The diameter of the air inlet 22 is related to the length and bending degree of the air duct 23, so that the wind can flow from one end to the other end of the air duct 23 with minimum wind resistance.

[0092] As a realizable way, as Figure 6As shown, the first temperature detection assembly 30 comprises a heat-conducting member 31, a heating member 32 and temperature sensors 33, the heat-conducting member 31 is arranged along the extension direction of the air duct, the heating member 32 is located inside each air duct 23 and has the same distance from the two air inlets 22, the heating member 32 is used to heat the heat-conducting member 31, and the temperature sensors 33 are at least two, which are distributed on both sides of the heating member 32 and are arranged at intervals along the extension direction of the heat-conducting member 31.

[0093] The heating member 32 is a constant-power heating member 32.

[0094] The heat-conducting member 31 is made of metal with good heat conductivity, such as but not limited to copper sheet; the heating member 32 can be but is not limited to an electric heating wire, and the constant-power heating member 32 is conducive to ensuring the constant heat of the heat-conducting member 31 and avoiding measurement errors; the temperature sensors 33 can be any existing type of temperature sensor 33, and the temperature sensors 33 can be two, three or more to improve measurement accuracy.

PTC (Positive Temperature Coefficient) thermistor is a typical semiconductor resistor with temperature sensitivity. When the temperature exceeds a certain temperature (Curie temperature), the resistance will increase with the temperature in a step.

[0096] The first temperature detection assembly 30 in the embodiment is beneficial to collecting temperature information at different positions of the air duct extension direction, so as to calculate the wind speed and direction through heat loss.

[0097] In some embodiments, the heat-conducting member 31 forms a closed space inside the air duct 23, and the heating member 32 and the temperature sensors 33 are located inside the closed space.

[0098] In the embodiment, the heat-conducting member 31 forms a closed space inside the air duct 23, which is conducive to protecting the temperature sensors 33 and the heating member 32, avoiding the influence of rain or dust brought by the wind on the temperature sensors 33 and the heating member 32, ensuring the reliable work of the temperature sensors 33 and the heating member 32, and prolonging the service life.

[0100] It can be understood that the number of temperature sensors 33 in the embodiment is even, and the temperature sensors 33 are symmetrically distributed on both sides of the heating element 32, which is beneficial to improve the measurement accuracy.

[0101] In some embodiments, the temperature sensor 33 is located at a predetermined distance between the inside of the air duct and the air inlet.

[0102] The predetermined distance is determined according to the actual measurement accuracy, for example, but not limited to, 1cm-2cm.

[0105] The power of the heating element, the heating time, the interval time of temperature collection, the ambient temperature, the ambient humidity and the preset measurement error are determined in advance, wherein the preset measurement error is determined according to the actual working experience and the measurement accuracy.

[0106] During the measurement process, the heating element is powered on to heat, the heating element is heated at a constant power for a time t1 to heat the heat-conducting element, after the wind enters the inside of the air duct, the controller receives at least two temperatures T1, T2,..., Tn collected by the temperature sensor, n is greater than 2, after the heating element is powered off to stop heating for an interval time t2, the heating element continues to be powered on to work, and the above is repeated until the collection is completed.

[0107] The controller internally pre-designs a calculation model, and the collected temperature data, the ambient temperature and the measurement error are processed through nonlinear calculation to finally obtain the wind speed and wind direction data. For example, the principle of the wind direction and speed measuring device of the application can be summarized as follows: when there is no wind flowing through the surface of the heat-conducting element, the temperature of the temperature sensor will also be symmetrically distributed because of the symmetric distribution of the temperature sensor; when the laminar flow state air with a wind speed of Fs flows through the surface of the heat-conducting element in a certain direction, the wind will carry away part of the heat and form a thin thermal boundary layer on the surface, and the temperature of the temperature sensor will be distributed in a certain gradient, and the wind speed can be calculated according to the gradient distribution; the gradient distribution between the wind speeds collected by two or more different direction air ducts can be calculated to obtain the wind.
