Abstract
The invention discloses a kind of methods using gyro sensor measurement axial fan hub revolving speed, include the following steps: that gyro sensor is installed on axial fan hub by (1)；(2) angular speed Axz, Ayz and the Axy of gyro sensor real-time detection tri- axis of X, Y, Z rotation during wheel hub rotates；(3) according to Pythagorean theorem, the total real-time angular speed of available wheel hub is .The method disclosed in the present, no matter wheel hub rotation speed accurate meter can calculate the revolving speed of wheel hub in real time, in situation known to current wind, the master controller of blower can adjust the Windward angle of fan blade according to the revolving speed of the wheel hub, so that the safe and stable operation for pitch system of wind driven generator provides a strong guarantee.
Description
Technical field
The invention belongs to wind-driven generator field, in particular to one of field application gyro sensor measures wind
The method of machine hub rotation speed.
Background technique
The wheel hub installation of wind-driven generator is suspended from high aerial, and sufficiently bulky, rotation when can only estimate its revolving speed, nothing
Method accurately calculates the actual speed of wheel hub.Common G-senser sensor only measures ratio in the case where the wheel hub slow-speed of revolution
Relatively accurate, error in actual use is larger.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of application gyro sensors to measure axial fan hub revolving speed
Method.
The present invention adopts the following technical scheme:
A method of axial fan hub revolving speed being measured using gyro sensor, it is improved in that including following step
It is rapid:
(1) gyro sensor is installed on axial fan hub；
(2) the angular speed Axz of gyro sensor real-time detection tri- axis of X, Y, Z rotation during wheel hub rotates,
Ayz and Axy；
(3) according to Pythagorean theorem, the total real-time angular speed of available wheel hub is
Further, in step (2), gyro sensor is real-time detection X, Y, Z tri- during wheel hub rotates
AD value corresponding to the angular speed of axis rotation, can be obtained magnitude of angular velocity multiplied by 0.06 °/s for AD value.
The beneficial effects of the present invention are:
The method disclosed in the present, no matter wheel hub rotation speed can calculate turning for wheel hub by accurate meter in real time
Speed, in situation known to current wind, the master controller of blower can adjust fan blade according to the revolving speed of the wheel hub
Windward angle, so that the safe and stable operation for pitch system of wind driven generator provides a strong guarantee.
Detailed description of the invention
Fig. 1 is the schematic illustration of 1 disclosed method of the embodiment of the present invention.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right below in conjunction with drawings and examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment 1, present embodiment discloses a kind of methods using gyro sensor measurement axial fan hub revolving speed, including
Following steps:
(1) gyro sensor is installed on axial fan hub, which can be any with real-time detection space
Direction vector, the variation of the angular speed of any time；
(2) the angular speed Axz of gyro sensor real-time detection tri- axis of X, Y, Z rotation during wheel hub rotates,
Ayz and Axy；
(3) as shown in Figure 1, according to Pythagorean theorem, the total real-time angular speed of available wheel hub is
In step (2), the angle of gyro sensor real-time detection tri- axis of X, Y, Z rotation during wheel hub rotates
Magnitude of angular velocity can be obtained multiplied by 0.06 °/s in AD value by AD value corresponding to speed.Such as the AD value of certain axis is 200, then angle is fast
Degree is 200 × 0.06 °/s=12 °/s.
