The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0036] The solution of the present application can be applied in the measurement scenario of vector wind speed, and can measure the direction and wind speed information of the wind speed. Specifically, the solution can be designed for measuring wind speed measurement equipment, such as Figure 1 As shown, the measuring device may include a porous pipe with one end arranged in a plane, and N optical fiber sensor probes uniformly distributed around the center of the plane of the porous pipe. In order to measure wind speed information, the measuring device may also include a heat source arranged in the middle of the plane of the porous pipe, and N optical fiber sensor probes are uniformly distributed around the heat source, the optical fiber sensor probe is a direct bandgap semiconductor material, and the heating method of the heat source is light source heating or power supply heating; the optical fiber sensor probe is a gallium arsenide crystal.

[0037] like Figure 2 As shown, the method of the present application can determine the wind direction and wind speed in the vector wind field. When measuring the wind direction, during the change of the wind direction, it can be determined whether the wavelength acquisition data of the current N optical fiber sensor probes is linearly uniformly changing or nonlinearly uniformly changing. If it is linearly uniformly changing, it can be solved directly. If it is nonlinearly uniformly changing, the number of optical fiber sensor probes can be increased, so that the discrete area of ​​the nonlinear change process is continuously reduced and gradually approaches linearization, thereby improving the direction accuracy, that is, continuously reducing the result error of the wind direction, and obtaining an approximate solution. In the process of determining the wind speed (or wind intensity), intensity demodulation can be performed according to the light intensity or wavelength demodulation can be performed according to the wavelength, so as to determine the wind speed information, and the wind speed information includes the intensity information of the wind speed.

[0038] Specifically, in the process of determining the wind speed direction, this solution can obtain the wavelength acquisition data of each optical fiber sensor probe in the target wind field, and determine the first sensor, the second sensor and the third sensor according to the wavelength acquisition data, wherein the first sensor can be the optical fiber sensor probe with the largest wavelength offset in the target wind field, the second sensor is the optical fiber sensor probe adjacent to the first sensor in the first direction (such as clockwise direction), and the third sensor is the optical fiber sensor probe adjacent to the first sensor in the second direction (such as counterclockwise direction). After determining the first sensor, the second sensor and the third sensor, the relevant data corresponding to each sensor can be obtained, such as the first relevant data, the second relevant data and the third relevant data, wherein the first relevant data includes the first wavelength offset of the first sensor in the target wind field and the first maximum wavelength offset of the first sensor in the maximum offset wind field; the second relevant data includes the second wavelength offset of the second sensor in the target wind field and the third wavelength offset of the second sensor in the maximum offset wind field corresponding to the first sensor; the third relevant data includes the fourth wavelength offset of the third sensor in the target wind field. After determining the first relevant data, the second relevant data and the third relevant data, the wind speed direction of the target wind field can be further determined.

[0039] In a specific example, Figure 3 As shown, N optical fiber sensor probes are installed in the porous pipe, and a heat source heated by a light source or a power source is placed in the center of the pipe so that the optical fiber sensor arrays evenly arranged around it have the same temperature. A vector wind field F 风 (r,θ) passes through the plane of the optical fiber sensor probe, and its wind direction and wind strength are determined by θ and r respectively. The specific solution process is: The wind speed direction θ of the vector wind speed measurement method can be obtained by the following analysis: When the wind speed directions are Direction 1 and Direction 2 respectively, the optical fiber sensor probe x reaches the maximum wavelength deviation Δλ xmax and minimum wavelength shift Δλ xmin , at this time the wavelength offset of the optical fiber sensor probe x-1 is Δλ x-1 Assuming that the wavelength drift of the N optical fiber sensor probes changes linearly and uniformly with the change of wind speed direction θ, then when the vector wind field F 风 When (r,θ) passes through the plane, if the wavelength offset Δλ of the optical fiber sensor probe x among the N optical fiber sensor probes x Maximum, the wavelength offset of the optical fiber sensor probe x-1 is Δλ x-1 ', the wavelength offset of the optical fiber sensor probe x+1 is Δλ x+1 The wind speed direction θ at this time can be determined by the following formula:

[0040]

[0041] Among them, θ represents the wind speed direction, x represents the first sensor, x-1 represents the second sensor, x+1 represents the third sensor, Δλ x represents the first wavelength shift detected by the first sensor, Δλ x-1 ' represents the second wavelength shift detected by the second sensor; Δλ x-1 represents the third wavelength shift of the second sensor; Δλ xmax represents the first maximum wavelength shift of the first sensor; Δλ x+1 Represents the fourth wavelength offset of the third sensor.

[0042] In the process of determining the wind speed information, the heat source can be turned on so that each fiber optic sensor probe has the same temperature; the spectral drift information of each fiber optic sensor probe in the target wind field is obtained; and the wind speed information is obtained by demodulation according to the spectral drift information. Among them, demodulation according to the spectral drift information may include intensity demodulation according to light intensity or wavelength demodulation according to wavelength, so as to determine the wind speed intensity information. Among them, if Figure 4 As shown, the heating method of the heat source adopts a heating light source or a heating power source for heating; the optical fiber sensor probe (or optical fiber probe) is used to detect the wind field in the environment to be tested. The optical fiber sensor probe obtains the spectral drift information in the following way: the light emitted by the detection light source enters the gallium arsenide crystal after passing through the optical fiber coupler, and the reflected light after passing through the gallium arsenide crystal is transmitted to the detection instrument through the transmission optical fiber and the optical fiber coupler. The detection instrument converts the received light into a digital signal, which can be processed and displayed by the controller, such as determining the spectral drift information based on the digital information.

[0043] Among them, for demodulation according to light intensity and demodulation according to wavelength, the specific method is to analyze the relationship between different wind speeds and temperatures and the relationship between temperature and light intensity or wavelength. Figure 5 As shown, Figure 5 This is the temperature field simulation result of the fiber optic sensor probe of the measuring device of an embodiment of the present application under a specific wind speed. It can be seen that the wind speed brings about temperature changes. The light intensity changes and wavelength changes can be analyzed through multiple fiber optic sensor probes to determine the corresponding wind speed.

[0044] In addition, in addition to using wavelength and light intensity demodulation, the demodulation method used in this application can also adopt a more effective demodulation method by analyzing the characteristics of the optical fiber sensor probe used, which can be configured specifically according to needs. The heating medium used in this application can be an optical fiber sensor probe heated by a light source, or it can be replaced by other materials with high thermal conductivity and low energy consumption, such as silicon columns. In addition to realizing wind speed measurement, this application can also realize vector measurement of other fluids.

[0045] Specifically, the embodiment of the present application provides a vector wind speed measurement method, which is based on a measurement device to complete the measurement, wherein the measurement device includes a porous pipe with a plane at one end, N optical fiber sensor probes uniformly distributed around the center of the plane of the porous pipe, such as Figure 6 As shown, the method includes:

[0046] Step 602: Acquire wavelength acquisition data of each optical fiber sensor probe in the target wind field, and determine the first sensor with the largest wavelength offset according to the wavelength acquisition data.

[0047] Step 604: extract first relevant data of the first sensor, where the first relevant data includes a first wavelength offset of the first sensor in the target wind field and a first maximum wavelength offset of the first sensor in the maximum offset wind field.

[0048] Step 606: determine a second sensor adjacent to the first sensor in the first direction, and extract second related data of the second sensor, wherein the second related data includes a second wavelength offset of the second sensor in the target wind field and a third wavelength offset of the second sensor in the maximum offset wind field corresponding to the first sensor.

[0049] Step 608: determine a third sensor adjacent to the first sensor in the second direction, and extract third related data of the third sensor, where the third related data includes a fourth wavelength offset of the third sensor in the target wind field.

[0050] Step 610: Determine the wind speed direction of the target wind field according to the first relevant data, the second relevant data and the third relevant data.

[0051] The solution of the present application can be applied in the measurement scenario of vector wind speed, and can measure the direction and wind speed information of wind speed. Specifically, the solution can be designed for measuring wind speed measurement equipment, and the measurement equipment may include a porous pipe with one end arranged in a plane, and N optical fiber sensor probes uniformly distributed around the center of the plane of the porous pipe. In the process of determining the direction of wind speed, the solution can obtain the wavelength acquisition data of each optical fiber sensor probe in the target wind field, and determine the first sensor, the second sensor and the third sensor based on the wavelength acquisition data, wherein the first sensor can be the optical fiber sensor probe with the largest wavelength offset in the target wind field, the second sensor is the optical fiber sensor probe adjacent to the first sensor in the first direction (such as clockwise), and the third sensor is the optical fiber sensor probe adjacent to the first sensor in the second direction (such as counterclockwise). After determining the first sensor, the second sensor, and the third sensor, relevant data corresponding to each sensor can be obtained, such as the first relevant data, the second relevant data, and the third relevant data, wherein the first relevant data includes the first wavelength offset of the first sensor in the target wind field and the first maximum wavelength offset of the first sensor in the maximum offset wind field; the second relevant data includes the second wavelength offset of the second sensor in the target wind field and the third wavelength offset of the second sensor in the maximum offset wind field corresponding to the first sensor; the third relevant data includes the fourth wavelength offset of the third sensor in the target wind field. After determining the first relevant data, the second relevant data, and the third relevant data, the wind speed direction of the target wind field can be further determined.

[0052] This solution can compare the detection data of the second sensor and the third sensor in the target wind field, and further analyze the deviation of the wind field to determine the wind speed direction. Specifically, as an optional embodiment, the determination of the wind speed direction of the target wind field based on the first relevant data, the second relevant data and the third relevant data includes: comparing the second wavelength offset of the second sensor and the fourth wavelength offset of the third sensor, and determining the comparison result; determining the wind speed direction of the target wind field based on the comparison result, the first relevant data and the second relevant data. Specifically, as an optional embodiment, the process of determining the wind speed direction of the target wind field based on the comparison result, the first relevant data and the second relevant data is determined according to the following formula:

[0053]

[0054] Among them, θ represents the wind speed direction, x represents the first sensor, x-1 represents the second sensor, x+1 represents the third sensor, Δλ x represents the first wavelength shift detected by the first sensor, Δλ x-1 ' represents the second wavelength shift detected by the second sensor; Δλ x-1represents the third wavelength shift of the second sensor; Δλ xmax represents the first maximum wavelength shift of the first sensor; Δλ x+1 Represents the fourth wavelength offset of the third sensor.

[0055] This solution can also dynamically adjust the number of fiber optic sensor probes to adapt to the changes of fiber optic sensor probes in different situations. For example, when the data of multiple fiber optic sensor probes change nonlinearly and uniformly, the number of fiber optic sensor probes can be increased so that the data of multiple fiber optic sensor probes tend to change linearly and uniformly, thereby solving the problem. Specifically, as an optional embodiment, the method also includes: in the process of wind speed direction change, determining whether the wavelength acquisition data of N fiber optic sensor probes changes nonlinearly and uniformly, and if so, increasing the number of fiber optic sensor probes. The change in the number of fiber optic sensor probes can be increased by automatic control, such as controlling the lifting and lowering of the fiber optic sensor probes to adjust the number of fiber optic sensor probes. In this solution, after the acquisition data changes non-uniformly, the number of sensor probes is increased to gradually subdivide the change interval, thereby achieving the purpose of approaching uniform change.

[0056] In order to detect the wind speed, a heat source can also be set to make multiple fiber optic sensor probes in a uniform temperature field, so as to analyze the temperatures of different fiber optic sensor probes to determine the wind speed information. Specifically, as an optional embodiment, the measuring equipment also includes a heat source arranged in the middle of the porous pipe plane, and the fiber optic sensor probe is a direct bandgap semiconductor material. The method also includes: turning on the heat source so that each fiber optic sensor probe has the same temperature (the difference between them is less than the preset temperature difference); obtaining the spectral drift information of each fiber optic sensor probe in the target wind field; demodulating according to the spectral drift information to obtain wind speed information.
