Description

An integrated wind speed and direction measuring instrument Technical Field

[0001] The present application relates to the field of wind speed and direction measuring instruments, and in particular to an integrated wind speed and direction measuring instrument. Background Art

[0002] Wind load measurement is one of the most fundamental aspects of meteorological observation. Wind load measurement primarily requires measuring two physical quantities: wind speed and wind direction. Common instruments used to measure wind load include mechanical anemometers, ultrasonic anemometers, dynamic pressure anemometers, thermal anemometers, laser wind radars, and wind profiler radars.

[0003] The cup-type mechanical anemometer measures wind speed by rotating a set of mechanical rotating parts with a wind cup, and measures wind direction by rotating another set of mechanical rotating parts with a wind vane. It is the simplest and most widely used instrument among many instruments used to measure wind loads.

[0004] Although the cup-type mechanical anemometer is simple and reliable, in order to ensure that the wind speed and wind direction can be measured separately, two sets of independent mechanical rotating parts are required. The complex mechanical structure easily leads to low reliability and makes it difficult to meet the needs of long-term observation. Due to long-term wear and tear, the service life of the cup-type mechanical anemometer is unlikely to exceed two years, especially under extremely harsh conditions such as low temperature, strong wind, and sand and gravel in the polar regions. It is even more difficult to put it into normal use. Technical issues

[0043] The specific implementation of this application will be further described below with reference to the accompanying drawings.

[0044] The present application discloses an integrated wind speed and direction measuring instrument. Please refer to the structural schematic diagram shown in Figure 1. The integrated wind speed and direction measuring instrument includes a mechanical rotating component 1, a plurality of wind receiving components, an angle sensor 2 and a signal processing circuit 3. All wind receiving components include a plurality of wind cups 4 and a wind vane 5. The structures and specifications of all wind cups 4 are the same. Based on the structure of a traditional wind cup wind speed and direction measuring instrument, the wind receiving component generally includes three or more wind cups 4. The structure of the wind vane 5 is different from that of the wind cup 4. The wind vane 5 can actually adopt various structures, such as a cup-shaped structure with the cup 4. In one embodiment, in order to facilitate production and have a better wind receiving effect, the wind vane 5 adopts a flat structure, such as the tail wing structure of a traditional wind vane.

[0045] All wind receiving components are evenly arranged along the circumference on the same horizontal plane and fixed on the mechanical rotating part 1 to form an asymmetric rotating structure. The openings of each wind cup 4 are arranged clockwise or counterclockwise, which is the same as the setting structure of the wind cup 4 in the traditional wind cup type wind speed and direction meter. The difference is that the present application fixes a wind vane 5 on the mechanical rotating part 1. As shown in Figure 1, the wind receiving component includes five wind cups 4 and a wind vane 5 as an example. The angle sensor 2 is fixed on the mechanical rotating part 1, and the signal processing circuit 3 is electrically connected to the angle sensor 2. The angle sensor 2 uses a commercially available high-speed angle sensor chip. The angle sensor 2 can detect the rotation angle of the mechanical rotating part 1 in real time and with high precision. The signal processing circuit 3 is a device used for signal processing and data analysis in the integrated wind speed and direction measuring instrument, and can be implemented using a single-chip microcomputer. The signal processing circuit 3 collects the rotation angle curve of the asymmetric rotating structure through the angle sensor 2, and obtains the wind speed measurement value and the wind direction angle measurement value based on the rotation angle curve. The rotation angle curve indicates the rotation angle of the asymmetric rotating structure. Curves of change over time.

[0046] As can be seen from Figure 1, the cups and wind vanes in this application are both fixed to the same mechanical rotating component 1 and share the same mechanical rotating component 1. The entire integrated wind speed and direction measuring instrument includes only one mechanical rotating component 1, which reduces the number of mechanical rotating components 1 compared to traditional cup wind speed and direction measuring instruments. However, since only one set of mechanical rotating components 1 is used, and the wind vane 5 has a different structure from the other cups 4, the wind receiving component is fixed to the mechanical rotating component 1 to form an asymmetric rotating structure. The rotation law of this asymmetric rotating structure is different from the rotation law of the traditional fully symmetrical cup wind speed and direction measuring instrument. Therefore, the method of calculating wind speed and wind direction in the integrated wind speed and direction measuring instrument of this application is also different from the traditional method:

[0047] 1. Obtain wind speed measurement value based on the rotation angle curve.

[0048] First, the rotation angle curve is converted into a rotation angular velocity curve, which indicates the rotation angular velocity of the asymmetric rotating structure. With rotation angle 's change curve.

[0049] The angular velocity of the asymmetric rotating structure is obtained by conversion Finally, determine the wind speed angular velocity curve obtained by wind tunnel test calibration and the rotation angular velocity of the asymmetric rotating structure. The corresponding wind speed is used as a wind speed measurement value, and the wind speed angular velocity curve indicates the corresponding relationship between the wind speed and the rotation angular velocity of the asymmetric rotating structure.

[0050] In the process of using the wind speed angular velocity curve to solve and obtain the wind speed measurement value, a filtering algorithm is generally used to filter the data to obtain a wind speed measurement value that meets specific usage requirements. Commonly used filtering algorithms include general averaging, sliding averaging, exponential averaging, etc.

[0051] 2. Obtain the wind direction measurement value based on the rotation angle curve.

[0052] From the above introduction, it can be seen that the process of solving the wind speed measurement value in this application is not greatly affected by the rotation law of the asymmetric rotating structure, but the rotation law of the asymmetric rotating structure has a greater impact on the solution of the wind direction measurement value.

[0053] In order to accurately calculate the wind direction measurement value, the rotation law of the asymmetric rotating structure is first introduced as follows. Taking the application scenario shown in Figure 2 as an example, when the wind direction is from right to left, the asymmetric rotating structure rotates counterclockwise under the action of the wind. When the wind vane 5 rotates to the position in the downwind direction, it is assumed that the downwind position is the 0° position in Figure 2. The torque of the asymmetric rotating structure gradually increases from the initial value, causing the rotation angular velocity of the asymmetric rotating structure to increase. When the wind vane 5 rotates to the 90° position in Figure 2, the torque of the asymmetric rotating structure reaches its maximum value, and the angular velocity of rotation When the wind vane 5 rotates 90°, the torque of the asymmetric rotating structure gradually decreases until the wind vane 5 rotates to 180°, at which point the torque of the asymmetric rotating structure returns to its initial value. After the wind vane 5 rotates 180°, it enters the upwind direction, and the rotation torque of the asymmetric rotating structure gradually decreases, resulting in the rotation angular velocity of the asymmetric rotating structure being When the wind vane 5 rotates to 270°, the rotational torque of the asymmetric rotating structure is minimum, and the rotational angular velocity of the asymmetric rotating structure is After the wind vane 5 rotates 270°, the rotational torque of the asymmetric rotating structure gradually increases, and the rotational angular velocity of the asymmetric rotating structure is Continue to decrease until the wind vane 5 rotates back to the 0° position in the downwind direction, and the rotational torque of the asymmetric rotating structure returns to the initial value. The rotational angular velocity of the asymmetric rotating structure is To reach the minimum value, repeat the above process.

[0054] Through the above analysis of the rotation law of the asymmetric rotating structure, it can be seen that in the process of each rotation of the asymmetric rotating structure, the rotation angular velocity of the asymmetric rotating structure is It is relatively stable, and its changes are mainly affected by the asymmetric structure of the wind-receiving component. Therefore, in the process of solving the wind direction measurement value, please refer to the flowchart shown in Figure 3. First, the rotation angle curve is converted into a rotation angular velocity curve. This step is the same as the step of converting the rotation angular velocity curve when solving the wind speed measurement value. The rotation angular velocity curve is further converted into a rotation angular acceleration curve. The rotation angular acceleration curve indicates the rotation angular acceleration of the asymmetric rotating structure. With rotation angle Then, the wind direction angle measurement value is obtained based on the rotation angular velocity curve and the rotation angular acceleration curve.

[0055] It should be noted that only when the asymmetric rotating structure is in a high-speed stable rotating state can it rotate according to the above rotation law, and then the wind direction measurement value can be calculated more accurately. Always reach the angular velocity threshold and rotate at an angular velocity When the duration of time within the angular velocity fluctuation range reaches the stability duration threshold, it is determined that the asymmetric rotating structure is in a high-speed stable rotation state. At this time, the step of calculating the wind direction angle measurement value based on the rotation angular velocity curve and the rotation angular acceleration curve is executed to calculate the wind direction measurement value. Otherwise, the detection is continued until the asymmetric rotating structure enters a high-speed stable rotation state. The angular velocity fluctuation range is a pre-set range. Based on this feature, the integrated wind speed and direction measuring instrument of the present application is particularly suitable for occasions with large wind loads, such as those in harsh polar wind environments. The higher the rotation speed of the asymmetric rotating structure, the higher the reliability of the calculated wind direction measurement value.

[0056] The above analysis of the rotation law of the asymmetric rotating structure can further determine that when the asymmetric rotating structure is in a high-speed stable rotation state, during each rotation of the asymmetric rotating structure, when the wind vane 5 is at a 0° windward position, the rotation angular velocity of the asymmetric rotating structure is Minimum; When the wind vane 5 is in the 180° leeward position, the angular velocity of the asymmetric rotating structure Maximum; when the wind vane 5 is at 90°, the rotation angular velocity The change is the maximum value, that is, the rotational angular acceleration of the asymmetric rotating structure The positive value is the largest; when the wind vane 5 is at 270°, the rotation angular velocity The change is the maximum value, that is, the rotational angular acceleration of the asymmetric rotating structure Therefore, the rotational angular velocity curve and the rotational angular acceleration curve are both in the form of sine-cosine curves, as shown in the schematic diagram in Figure 3.

[0057] Based on the above-mentioned changing rules of the rotation angular velocity curve and the rotation angular acceleration curve, the wind direction angle measurement values ​​obtained by solving the rotation angular velocity curve and the rotation angular acceleration curve include:

[0058] Determine the maximum angular velocity of the asymmetric rotating structure per rotation according to the rotation angular velocity curve and the minimum angular velocity The maximum angular acceleration of the asymmetric rotating structure per rotation is determined based on the rotation angular acceleration curve. and the minimum angular acceleration .

[0059] In one embodiment, in order to reduce the solution error, the maximum rotational angular velocity and the minimum rotational angular velocity of the rotational angular velocity curve in multiple consecutive rotation cycles are first determined respectively, and the maximum rotational angular acceleration and the minimum rotational angular acceleration of the rotational angular acceleration curve in multiple consecutive rotation cycles are determined respectively, and each rotation cycle covers a rotation angle of 360°.

[0060] Then, a clustering algorithm is used to cluster the maximum rotation angular velocity in multiple rotation cycles to obtain the maximum angular velocity. , clustering algorithm is used to cluster the minimum rotation angular velocity in multiple rotation cycles to obtain the minimum angular velocity , clustering algorithm is used to cluster the maximum rotational angular acceleration in multiple rotation cycles to obtain the maximum angular acceleration , clustering algorithm is used to cluster the minimum rotation angular acceleration in multiple rotation cycles to obtain the minimum angular acceleration . This can eliminate the interference of outliers.

[0061] Then according to the maximum angular velocity , minimum angular velocity , maximum angular acceleration and the minimum angular acceleration The wind direction angle measurement value is obtained by solving.

[0062] In one embodiment, in order to further improve the accuracy of the solution, first check whether the angle difference requirement is met: when it is detected that the angle difference requirement is met and and and When the angle difference requirement is met, the 、 、 and Solve to get the wind direction angle measurement value. Otherwise, redetermine the maximum angular velocity value , minimum angular velocity , maximum angular acceleration and the minimum angular acceleration .in, It is a preset deviation angle, and the value can be set according to actual conditions.

[0063] In utilizing 、 、 and When solving, first calculate the rough value of wind direction angle for:

[0064]

[0065] Then, based on the rough value of the wind direction angle Solve to get the wind direction angle measurement value One approach is to directly use the rough wind direction angle As a measurement of wind direction angle However, in order to improve the accuracy of the wind direction angle measurement value obtained by the solution, another approach is to determine the wind direction angle measurement value ,in, is the wind direction error angle calibrated by the wind tunnel test.

[0066] To verify the accuracy and reliability of wind load measurement results from the integrated anemometer of this application, this application conducted CFD (Computational Fluid Dynamics) simulations based on the structure of the integrated anemometer shown in Figure 1. During the simulations, single-phase external flow simulation was used. Based on the actual dimensions of the integrated anemometer, the virtual wind tunnel dimensions were set to 3m × 1.5m × 1.5m. The incoming wind speed was set to 2m / s, and the wind direction was along the 0° position shown in Figure 2, consistent with the initial orientation of wind vane 5. The simulation time was set to 10s. When the asymmetric rotating structure was in a high-speed, stable rotational state, the angular velocity and acceleration curves, converted from the actual measured rotation angle curve, were shown in Figure 5. It can be seen that the angular velocity and acceleration curves conform to the sine-cosine curve form within the error range, which is generally consistent with the theoretical analysis above. Furthermore, the wind speed measurement values ​​and wind direction angle measurement values ​​calculated according to the method of the present application are also basically accurate, which fully demonstrates the feasibility of the integrated wind speed and direction measuring instrument.
