[0038] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0039] See Figures 1-10The controllable wall-shaped wind field generating device of the present invention includes a wind field generating device, a testing device 1, and a control console 4. Since a single wind field simulation on computer software takes a considerable amount of time to obtain simulation results, multiple adjustments are required to obtain an ideal wind field if the settings of the simulation software or the operating state of the wind turbine are not ideal. The controllable wall-shaped wind field generating device of the present invention can adjust the operating state of each wind-driven motor 1001 of the wind turbine wall online, quickly obtain wind field parameters through the detection mechanism 103, greatly reducing the time required to obtain wind field data, and can adjust the operating state of each wind-driven motor 1001 to the optimal level based on the test results of each test. Furthermore, the data actually measured is more realistic and practical than the data obtained by computer simulation under ideal conditions.

[0040] See Figures 1-10 The wind farm generating device includes wind turbine walls, which are disposed on the front and sides of the testing device 1; wherein, the wind turbine wall disposed on the front of the testing device 1 is a front wind turbine wall 3; and the wind turbine wall disposed on the side of the testing device 1 is a side wind turbine wall 2.

[0041] The wind turbine wall includes a movable base 7, a support 8 mounted on the movable base 7, and a wind power generating mechanism 10 mounted on the support 8. A guide rail 5 is provided on the ground, extending along the X-axis of the frame 101 to constrain the movement of the movable base 7. A guide block is provided on the movable base 7 to cooperate with the guide rail 5. Multiple wind power generating mechanisms 10 are arranged in a matrix on the support 8. Each wind power generating mechanism 10 includes a blade 1002 and a wind drive motor 1001 for driving the blade 1002 to rotate. The wind drive motor 1001 is positioned... An adjustment mechanism is installed on the bracket 8. This position adjustment mechanism can adjust the row spacing or spacing of the wind generating mechanisms 10 arranged in a matrix on the bracket 8. For example, the bracket 8 is provided with multiple vertically arranged horizontal bars 9. The two ends of the horizontal bars 9 are installed on the bracket 8 by bolts. Multiple sets of wind generating mechanisms 10 are installed on the horizontal bars 9. The installation position of the horizontal bars 9 can be adjusted by loosening or tightening the bolts. The position of each wind drive motor 1001 on the same horizontal bar 9 can also be adjusted by loosening or tightening the bolts on the motor base. By adjusting the spacing and row spacing of the wind generating mechanisms 10 on the bracket 8, the wind field generated by the wind turbine wall can be actively controlled.

[0042] In addition to the manual adjustment method mentioned above, the position adjustment mechanism can also be adjusted automatically. For example, an automatic moving mechanism can be set on both sides of the horizontal bar 9 and on the motor base. The automatic moving mechanism can be implemented with reference to the "vertical moving mechanism" or "vertical driving mechanism" mentioned below. By controlling the rotation of the motor, the horizontal bar 9 and the motor base are moved to adjust the position of each group of wind generating mechanisms 10.

[0043] In addition, the wind-driven motor 1001 and blade 1002 on the wind turbine wall should be small motors and small blades. Under the condition that the working area of ​​the wind turbine wall is fixed, more small motors with small blades can be installed on the bracket 8. Compared with the traditional device that uses a single or a few large wind turbines to generate airflow, the airflow generated by the small motor is more stable and has a smaller range of influence. Therefore, this device can make more precise adjustments to a certain area of ​​the wind field and can generate wind fields of more shapes. The wind-driven motor 1001 is equipped with an encoder. The encoder transmits the speed data of the wind-driven motor 1001 to the control console 4 through wired or wireless transmission.

[0044] In this embodiment, the mobile base 7 is a wheeled mobile base that communicates with the control console 4, and the movement of the mobile base 7 can be controlled by the control console 4.

[0045] See Figures 1-10 The testing device 1 includes a frame 101, a mounting mechanism 102 for mounting the object to be tested, and a detection mechanism 103 mounted on the frame 101. The mounting mechanism 102 is used to move the object to be tested to a suitable position. The detection mechanism 103 is used to detect the wind field formed in the front wind turbine wall 3 and the side wind turbine wall 2, and upload the detection data to the control console 4. The control console 4 determines whether the simulated wind field meets the requirements, thereby adjusting the speed and direction of the wind drive motors 1001 in the front wind turbine wall 3 and the side wind turbine wall 2 to achieve active control of the wind field.

[0046] See Figures 1-10 The mounting mechanism 102 includes a mounting base 17 disposed on a frame 101, an X-axis mounting drive mechanism for driving the mounting base 17 to move along the length direction of the frame 101, a Y-axis mounting drive mechanism for driving the mounting base 17 to move along the width direction of the frame 101, and a Z-axis mounting drive mechanism for driving the mounting base 17 to move along the height direction of the frame 101; the object to be detected is mounted on the mounting base 17.

[0047] In this embodiment, the X-axis mounting drive mechanism includes a first mounting frame 11 and X-axis mounting moving mechanisms 12 disposed on both sides of the first mounting frame 11. The two sides of the first mounting frame 11 are mounted on both sides of the frame 101 via the X-axis mounting moving mechanisms 12. The X-axis mounting moving mechanisms 12 cause the first mounting frame 11 to move along the X-axis direction of the frame 101 on the frame 101.

[0048] The Y-axis mounting drive mechanism includes a second mounting frame 13 and Y-axis mounting moving mechanisms 14 disposed on both sides of the second mounting frame 13. The two sides of the second mounting frame 13 are mounted on both sides of the first mounting frame 11 via the Y-axis mounting moving mechanisms 14. The Y-axis mounting moving mechanisms 14 cause the second mounting frame 13 to move along the Y-axis direction of the frame 101 on the first mounting frame 11.

[0049] The Z-axis mounting drive mechanism includes a third mounting frame 15 and Z-axis mounting moving mechanisms 16 disposed on both sides of the third mounting frame 15. The third mounting frame 15 is mounted on the lower side of the second mounting frame 13 via a vertical guide mechanism 18 (i.e., a guide rod vertically disposed on the third mounting frame 15 and a guide hole or guide sleeve disposed on the second mounting frame 13). The Z-axis mounting moving mechanism 16 adopts a drive method combining a motor and a lead screw transmission mechanism. The mounting base 17 is rotatably connected to the third mounting frame 15, and the posture (or mounting angle) of the object to be detected can be adjusted by locking the locking screw at the hinge position.

[0050] With the above settings, the object to be detected (e.g., a drone) mounted on the mounting base 17 can be moved along the X-axis, Y-axis, and Z-axis directions of the frame 101, thereby automatically adjusting the object to be detected to the most suitable position. Furthermore, in this embodiment, the structures of the X-axis mounting movement mechanism 12 and the Y-axis mounting movement mechanism 14 can be implemented as described below as "vertical movement mechanism" or "vertical drive mechanism," or a drive method combining a motor and a lead screw transmission mechanism can be used.

[0051] See Figures 1-10The detection mechanism 103 includes a mounting frame 19 mounted on a frame 101, a detection module mounted on the mounting frame 19, and a detection drive mechanism 26 for driving the mounting frame 19 to move along the X-axis of the frame 101 (which can be implemented as a "vertical movement mechanism" or "vertical drive mechanism" hereinafter, or can be a drive method combining a motor and a lead screw transmission mechanism). The detection module includes a first detection module 20, a second detection module 21, and a third detection module 24. The first detection module 20 can move along the Y-axis of the frame 101; the second detection module 21 can move along the Z-axis of the frame 101; and the third detection module 24 can move along both the Y-axis and Z-axis of the frame 101.

[0052] In this embodiment, the first detection module 20, the second detection module 21, and the third detection module 24 are all modularly designed, which makes it easy to meet more working environment requirements and more types of environmental parameters to be detected by increasing or decreasing the number of modules and replacing sensors. In addition, a small number of detection sensors can be used to achieve comprehensive and wide-range wind field detection of the internal and external environments of the detection mechanism.

[0053] See Figures 1-10 The first detection module 20 is mounted on the crossbar 191 of the mounting frame 19, and includes a first detection sensor and a drive mechanism 25 for driving the first detection sensor to move along the Y-axis direction of the frame 101. The axial direction of the detection port of the first detection sensor is parallel to the Z-axis direction of the frame 101. The drive mechanism 25 includes a first drive motor and a lead screw transmission mechanism. The first drive motor is mounted on the mounting frame 19 and is connected to the first detection sensor through the lead screw transmission mechanism. The first drive motor drives the lead screw to rotate, thereby driving the first detection sensor mounted on the lead screw nut to move along the Y-axis direction of the frame 101.

[0054] See Figures 1-10 The second detection module 21 is mounted on the vertical rod 192 of the mounting frame 19, and includes a second detection sensor 211 and a vertical moving mechanism for driving the second detection sensor 211 to make vertical movements, wherein the axial direction of the detection port of the second detection sensor 211 is parallel to the Y-axis direction of the frame 101.

[0055] See Figures 1-10The third detection module 24 includes a pole 23, a sensing and detection mechanism disposed on the pole 23, and a Y-axis drive mechanism 27 for driving the pole 23 to move along the Y-axis direction of the frame 101. The Y-axis drive mechanism 27 is disposed on the upper and lower sides of the pole 23, and the Y-axis drive mechanism 27 also adopts a drive method combining a motor and a lead screw transmission mechanism. The sensing and detection mechanism includes a third detection sensor and a vertical drive mechanism for driving the third detection sensor to move vertically. The axial direction of the detection port of the third detection sensor is parallel to the X-axis direction of the frame 101.

[0056] See Figures 1-10 The vertical moving mechanism and the vertical driving mechanism have the same structure, including a sliding seat 212, a roller 213 and a vertical motor 214 disposed on the sliding seat 212; wherein, a slide rail is provided on the upright 23 or the vertical rod 192, a slide groove is provided in the sliding seat 212, and the upright 23 or the vertical rod 192 is installed in the slide groove; a sliding part that cooperates with the slide rail is provided on one side of the slide groove; the roller 213 is installed on the side of the sliding seat 212 opposite to the sliding part, and the wheel surface of the roller 213 presses against the upright 23 or the vertical rod 192; the vertical motor 214 is installed on the sliding seat 212, and its main shaft is connected to the roller 213; the second detection sensor 211 or the third detection sensor is installed on the sliding seat 212. The vertical motor 214 drives the roller 213 to rotate, causing the sliding seat 212 and the second detection sensor 211 or the third detection sensor mounted on the sliding seat 212 to move along the axis of the upright 23 or the vertical rod 192.

[0057] In this embodiment, the structures of the X-axis mounting and moving mechanism 12, the Y-axis mounting and moving mechanism 14, the vertical drive mechanism, and the vertical moving mechanism are all the same. Therefore, they all use a motor to drive the rollers to rotate, thereby driving the sliding seat 212 to move. Therefore, the structures of the X-axis mounting and moving mechanism 12 and the Y-axis mounting and moving mechanism 14 will not be described in detail.

[0058] See Figures 1-10 The first detection sensor, the second detection sensor 211, and the third detection sensor are all composite sensors. The composite sensor includes a three-dimensional barometric pressure sensor, a temperature sensor, and a laser rangefinder. The three-dimensional barometric pressure sensor is an array of barometric pressure sensors with different directions, used to measure barometric pressure values ​​in different directions.

[0059] See Figures 1-10 The test method for the controllable wall-shaped wind field generating device of the present invention includes the following steps:

[0060] S1. Control the front fan wall 3 and the side fan wall 2 to move to the initial position through the control console 4, and at the same time control the installation mechanism 102 and the detection mechanism 103 to move to the initial position. Then adjust the initial posture of the object to be detected in the installation mechanism 102 (i.e. the position furthest from the fan wall).

[0061] S2. Input control commands or target wind field parameters on the control console 4 to adjust the speed and direction of the wind drive motors 1001 in each wind power generation mechanism 10 on the wind turbine wall;

[0062] S3. The console 4 issues a movement plan instruction to the mounting frame 19 and the first detection module 20, the second detection module 21 and the third detection module 24 mounted on the mounting frame 19. When the first detection module 20, the second detection module 21 and the third detection module 24 reach each position on the rack 101, they transmit the coordinate data of that position as well as the collected air pressure data and temperature data to the console 4.

[0063] S4, console 4 saves and processes the received coordinate data, air pressure data and temperature data, and compares the collected coordinate data, air pressure data and temperature data and the processed coordinate data, air pressure data and temperature data with the control commands or target wind field parameters input to console 4; then, console 4 adjusts the direction and speed of the wind drive motor 1001 of the wind turbine wall according to the control strategy;

[0064] S5. Repeat steps S2-S4 until the collected data (coordinate data, air pressure data, and temperature data) and the processed data (coordinate data, air pressure data, and temperature data) satisfy the control commands or target wind field parameters input into console 4.

[0065] S6. Move the detection mechanism 103 to the initial position, and then move the installation mechanism 102 to the initial position as well. Install the object to be tested on the mounting base 17. Adjust the installation height and angle of the object to be tested. Drive the mounting base 17 and the object to be tested on the mounting base 17 through the X-axis installation drive mechanism, Y-axis installation drive mechanism and Z-axis installation drive mechanism to move the object to be tested to the most suitable position for testing. The most suitable position means that the data (coordinate data, air pressure data and temperature data) detected at this position meets the input control command or target wind field parameters, and the turbulence is the lowest at this position under the condition of meeting the turbulence condition. The wind field parameters at this position are more stable than other positions.

[0066] In step S4, the data processing steps are as follows:

[0067] S41. The detection mechanism 103 moves in the X-axis direction, and the various sensor modules on the detection mechanism 103 (i.e., the first detection module 20, the second detection module 21 and the third detection module 24) move in the Y-axis or Z-axis direction of the frame 101 and collect coordinate data, air pressure data and temperature data at various positions on different planes. Then, the above data is recorded in the format P (X-axis coordinate of data acquisition position, Y-axis coordinate of data acquisition position, Z-axis coordinate of data acquisition position, acquisition time, air pressure value 1, air pressure value 2, air pressure value 3, air pressure value 4, air pressure value 5, air pressure value 6, temperature value). Finally, the collected data is transmitted to the control console 4.

[0068] S42, the console 4 calculates the wind speed and direction at different locations by processing data collected from different locations by various sensor detection modules (i.e., the first detection module 20, the second detection module 21 and the third detection module 24), and then calculates the wind field parameters of a certain planar area or a certain volume space by using the wind speed and direction.

[0069] In step S42, the planar region is a planar region consisting of the acquisition position coordinates of several sensor detection modules; the volume space is a volume space consisting of the acquisition position coordinates of several sensor modules.

[0070] In step S42, the steps for calculating the wind field parameters of a certain planar region or a certain volume space are as follows:

[0071] S421. Suppose we want to process a certain wind field parameter K at n locations on a certain plane, denoted as K1~K2. n The wind field parameters mentioned include, but are not limited to, airflow speed, airflow direction, airflow turbulence, air pressure, and temperature.

[0072] S422. Divide the parameter K into t levels, and denote each level as L. i Where i = 1, 2, ..., t; let the level L be... i The quantity is denoted as z i ,in i = 1, 2, ..., t;

[0073] S423. Calculate the rank proportion β(L) of parameter K for a certain planar region. i ) and the maximum continuous proportion α(L) i ):

[0074]

[0075] For the obtained levels L of n positions iThe parameter is used to calculate the maximum number of adjacent ranks L: the parameter can be modified to this value and denoted as LN. i ,but,

[0076]

[0077] S424. Calculate the parameters of a certain volume segment:

[0078] (1) Measure n wind field parameters H from multiple adjacent planes, denoted as H1~H2. n The wind field parameters include, but are not limited to, airflow speed, airflow direction, airflow turbulence, air pressure, and temperature; they are arranged according to the positional relationship of the measured parameters and displayed and stored in the console 4 in ways including but not limited to coordinate graphs, planar diagrams, and lists.

[0079] (2) Average the data measured in (1) above to obtain the average parameter of a target in a certain space:

[0080]

[0081] Example 2:

[0082] This embodiment provides a method for detecting wind field parameters in the natural environment or wind field parameters generated by the object being detected. The data processing method is the same as in Embodiment 1, including the following steps:
