Fig. 3 is a schematic flow chart of a method for detecting the quality of a wind speed sensor according to an embodiment of the present disclosure. In this embodiment, the method for detecting the quality of the wind speed sensor is applied to the control device 11 in the wind speed sensor field calibration system 10, where the control device 11 stores a source tracing correspondence relationship between a secondary wind speed value measured by the secondary speed measurement device 13 and different standard wind speed values corresponding to at least one wind speed sensor. The specific process and steps of the wind speed sensor quality detection method shown in FIG. 3 are described in detail below.
And S210, identifying the type of the wind speed sensor to be detected, and acquiring a target tracing corresponding relation corresponding to the wind speed sensor to be detected according to the identification result.
In this embodiment, when the control device 11 needs to perform thread quality detection on the wind speed sensor to be detected, type identification is performed on the wind speed sensor to be detected, type information corresponding to the wind speed sensor to be detected is obtained, a source tracing corresponding relationship corresponding to the type information is correspondingly searched in the memory 111, and then the searched source tracing corresponding relationship is used as a target source tracing corresponding relationship corresponding to the wind speed sensor to be detected.
Step S220, controlling the wind speed adjusting device 12 to adjust the wind speed according to each target secondary wind speed value in the target tracing correspondence, so as to obtain a wind speed measurement value correspondingly measured by the wind speed sensor to be detected when the current measured wind speed value of the secondary speed measuring device 13 is the same as the target secondary wind speed value.
In this embodiment, when the wind speed sensor to be detected works in the field wind tunnel cavity where the wind speed adjusting device 12 and the secondary speed measuring device 13 are located, the control device 11 will screen out all secondary wind speed values whose values are within the wind speed adjusting range from the target tracing correspondence corresponding to the wind speed sensor to be detected according to the wind speed adjusting range corresponding to the wind speed adjusting device 12, and then select a certain number of secondary wind speed values from all the screened secondary wind speed values to adjust the wind speed currently provided by the wind speed adjusting device 12. The selected secondary wind speed value is the target secondary wind speed value in the target tracing corresponding relation, and the total number of the target secondary wind speed values is not more than the number of all screened secondary wind speed values.
The control device 11 controls the wind speed adjusting device 12 to adjust the wind speed, and at the same time, monitors whether the current measured wind speed value of the secondary speed measuring device 13 is the same as a target secondary wind speed value. When the control device 11 monitors that the current wind speed value measured by the secondary speed measurement device 13 is the same as a certain target secondary wind speed value, the control device 11 correspondingly obtains the current wind speed measurement value measured by the wind speed sensor to be detected with respect to the wind speed adjustment device 12, so as to obtain all the wind speed measurement values of the wind speed sensor to be detected corresponding to the target secondary wind speed value.
Step S230, calculating a measurement error of the wind speed sensor to be detected corresponding to each target secondary wind speed value according to all wind speed measurement values of the wind speed sensor to be detected and all target standard wind speed values in the target tracing correspondence.
In this embodiment, after the control device 11 obtains all wind speed measurement values corresponding to the target secondary wind speed value of the wind speed sensor to be detected, all target standard wind speed values corresponding to the target secondary wind speed value are obtained from the target tracing correspondence, where each target standard wind speed value corresponds to one target secondary wind speed value. Then, the control device 11 calculates the measurement error of the wind speed sensor to be detected corresponding to each target secondary wind speed value according to all the wind speed measurement values of the wind speed sensor to be detected and all the target standard wind speed values in the target tracing correspondence.
Optionally, the step of calculating a measurement error of the wind speed sensor to be detected corresponding to each target secondary wind speed value according to all wind speed measurement values of the wind speed sensor to be detected and all target standard wind speed values in the target tracing correspondence includes:
calculating a linear regression equation between the standard wind speed value corresponding to the wind speed sensor to be detected and the wind speed measured value according to all the wind speed measured values of the wind speed sensor to be detected and all the target standard wind speed values in the target tracing correspondence;
calculating a theoretical standard wind speed value corresponding to the wind speed measured value corresponding to each target secondary wind speed value at the linear regression equation;
and carrying out subtraction operation on the wind speed measurement value corresponding to each target secondary wind speed value and the corresponding theoretical standard wind speed value to obtain a measurement error corresponding to the target secondary wind speed value.
The linear regression equation is used for expressing the functional relationship between the wind speed measurement value of the wind speed sensor to be detected in the field wind tunnel and each corresponding standard wind speed value in the wind speed measurement laboratory, and can be obtained by adopting a least square method.
And step S240, judging whether the wind speed sensor to be detected is qualified according to all the calculated measurement errors.
In this embodiment, after the control device 11 obtains the measurement error of the wind speed sensor to be detected corresponding to each target secondary wind speed value, it will determine whether the wind speed sensor to be detected is currently qualified according to a preset error threshold value matched with the type of the wind speed sensor to be detected.
Optionally, the step of determining whether the wind speed sensor to be detected is qualified according to all the calculated measurement errors includes:
searching a preset error threshold corresponding to the wind speed sensor to be detected according to the identification result;
and comparing the calculated absolute value of each measurement error with the preset error threshold value, and judging that the wind speed sensor to be detected is qualified when the absolute value is not greater than the preset error threshold value.
The control device 11 traces the source of the field quality detection standard of the wind speed sensor to be detected by executing the above-mentioned wind speed sensor quality detection method, and introduces the standard wind speed value of the wind speed measurement laboratory into the field quality detection according to the tracing correspondence between the secondary wind speed value of the wind speed sensor to be detected and the standard wind speed value, so as to perform quality detection processing with high detection accuracy and high detection precision on the wind speed sensor to be detected based on the standard wind speed value of the wind speed measurement laboratory.
Fig. 4 is a second schematic flow chart of a method for detecting a quality of a wind speed sensor according to an embodiment of the present application. In the embodiment of the present application, before the step S210, the wind speed sensor quality detection method may further include a step S207, a step S208, and a step S209.
Step S207, aiming at each wind speed sensor, acquiring an experimental wind speed value correspondingly measured by the wind speed sensor in a wind speed measurement laboratory and under different standard wind speed values.
In this embodiment, the control device 11 may obtain, through the communication unit 113, experimental wind speed values measured by various wind speed sensors when the wind speed sensors are located in a wind speed measurement laboratory and are subjected to wind forces corresponding to different standard wind speed values, where one experimental wind speed value of the wind speed sensor corresponds to one standard wind speed value.
Step S208, according to each experimental wind speed value of the wind speed sensor within the wind speed adjusting range of the wind speed adjusting device 12, controlling the wind speed adjusting device 12 to adjust the wind speed, so as to obtain a secondary wind speed value correspondingly measured by the secondary speed measuring device 13 when the current wind speed value measured by the wind speed sensor is the same as the experimental wind speed value.
In this embodiment, after acquiring all the experimental wind speed values of the wind speed sensor, the control device 11 may screen out each experimental wind speed value having a value within the wind speed adjusting range of the wind speed adjusting device 12 from all the experimental wind speed values, and adjust the wind speed by the wind speed adjusting device 12 according to each screened experimental wind speed value.
The control device 11 controls the wind speed adjusting device 12 to adjust the wind speed, and at the same time, monitors whether the current wind speed value measured by the wind speed sensor for the wind speed adjusting device 12 is the same as a screened experimental wind speed value. When the control device 11 monitors that the current wind speed value measured by the wind speed sensor is the same as a certain screened experimental wind speed value, the control device 11 correspondingly obtains the current secondary wind speed value measured by the secondary speed measurement device 13, so as to obtain all secondary wind speed values of the secondary speed measurement device 13 corresponding to the screened experimental wind speed value.
Step S209, a corresponding relationship between a secondary wind speed value corresponding to the same experimental wind speed value and a standard wind speed value is created, and a source tracing corresponding relationship corresponding to the wind speed sensor is obtained.
In this embodiment, after the control device 11 obtains the secondary wind speed value and the standard wind speed value corresponding to each screened experimental wind speed value of the wind speed sensor, the secondary wind speed value corresponding to the same experimental wind speed value is numerically associated with the standard wind speed value, so as to generate the traceability corresponding relationship corresponding to the wind speed sensor.
Fig. 5 is a third schematic flow chart of a method for detecting a quality of a wind speed sensor according to an embodiment of the present application. In the embodiment of the present application, the method for detecting the quality of the wind speed sensor may further include step S250, step S260, step S270, and step S280.
And S250, when the wind speed sensor to be detected is qualified, calculating a wind speed measurement linear equation corresponding to the wind speed sensor to be detected according to all wind speed measurement values and all target standard wind speed values of the wind speed sensor to be detected.
In this embodiment, the wind speed measurement linear equation is used to represent the measurement capability of the corresponding wind speed sensor to be detected when performing wind speed measurement on a standard wind speed value. The wind speed measurement linear equation can be calculated by the control device 11 by using a linear differential method or a linear regression method.
And step S260, calculating a wind speed calculation value corresponding to each standard wind speed value of the wind speed sensor to be detected in a preset standard wind speed range according to the wind speed measurement linear equation.
In this embodiment, the preset standard wind speed range may include the wind speed adjusting range of the wind speed adjusting device 12, or may be independent of the wind speed adjusting range of the wind speed adjusting device 12. For example, when the wind speed adjusting range of the wind speed adjusting device 12 is 0m/s to 10m/s, the preset standard wind speed range may be 0m/s to 40m/s, or 20m/s to 40 m/s. The control device 11 may calculate a wind speed calculation value corresponding to the wind speed sensor to be detected, which is reflected by the wind speed measurement linear equation, of each standard wind speed value within the preset standard wind speed range according to the wind speed measurement linear equation currently corresponding to the wind speed sensor to be detected.
And step S270, searching and acquiring an experimental wind speed value corresponding to each standard wind speed value of the wind speed sensor to be detected within a preset standard wind speed range according to the identification result.
