2. The sensing device of claim 1, wherein the support roller supports the web, the first sensing assembly includes a first sensor group located on a side of the web facing away from the support roller, and the second sensing assembly includes a second sensor group and a third sensor group located on sides of the two wings facing away from the support roller, respectively.
3. The sensing device of claim 2, wherein the stringer includes an axis of symmetry between two of the strakes, the two strakes being symmetrically disposed about the axis of symmetry, the first sensor set including first and second web sensors on opposite sides of the axis of symmetry, respectively.
4. The sensing device of claim 3, wherein the second and third sensor sets each comprise first and second sail sensors arranged linearly along a lengthwise extension of the sail.
5. The sensing device of claim 4, wherein the second sensor set and the third sensor set each further comprise a signal sensor disposed opposite the first sail sensor and/or the second sail sensor with respect to the sail.
6. The detecting device according to claim 5, further comprising two first moving frames, wherein the two first moving frames are respectively located at two sides of the symmetry axis, the first web sensor and the second web sensor are respectively disposed on the two first moving frames, and the first wing sensor is disposed on the first moving frames, and the two first moving frames are configured to be relatively close to or relatively far away from each other.
7. The detecting device for detecting the rotation of a motor rotor according to claim 6, further comprising first driving devices respectively connected with the two first moving frames for driving the first moving frames to move.
8. The detection device according to claim 6, further comprising two second movable frames, two of the second movable frames being respectively located at both sides of the symmetry axis, the second plate sensor and the signal sensor being disposed on the second movable frames, and the two second movable frames being configured to be relatively close to or relatively far from each other in synchronization with the first movable frame.
9. The detection apparatus of claim 8, wherein both of the second moving brackets are further configured to be movable in a direction toward or away from the web.
10. The detecting device for detecting the rotation of the motor rotor according to the claim 8, further comprising second driving devices respectively connected with the two second moving frames for driving the second moving frames to move.
