| description | The invention discloses a method for measuring an angle of an inner frame of a multi-frame pod by an electric eddy-current transducer. The method comprises steps as follows: the electric eddy-current transducer and an induction steel disc are installed on a to-be-measured inner frame and an installation frame of the inner frame respectively; when the to-be-measured inner frame rotates relative to the installation frame, the distance between the electric eddy-current transducer and the induction steel disc is changed, and the electric eddy-current transducer outputs a voltage signal V related with distance change; the voltage signal output by the electric eddy-current transducer is subjected to filter and analog-digital conversion, and meanwhile, the distance h between the electric eddy-current transducer and the induction steel disc is calculated according to a scaling factor of the electric eddy-current transducer and an amplification coefficient of analog-digital conversion; the angle between the to-be-measured inner frame and the installation frame of the inner frame is calculated according to the distance h between the electric eddy-current transducer and the induction steel disc. The size and the weight of a multi-frame pod system can be reduced, the friction force can be reduced, and high-precision angle measurement can be realized. |
