Torque-pitch-phase angle-rotating speed integrated measuring device and method based on phonic wheel

The invention relates to a torque-pitch-phase angle-rotating speed integrated measuring device and method based on a phonic wheel, which belong to the field of aero-engine measurement and control. The device disclosed by the invention comprises a torsion spring shaft (10), a phonic wheel component, a magnetic induction probe (11), a signal processing module (12) and a data display module (13). The phonic wheel component is installed on the torsion spring shaft with the non-circular section, one end face of the phonic wheel component is fixedly connected with a beta feedback rod of the propeller, and rotation and axial sliding motion of the phonic wheel component on the torsion spring shaft can be achieved. The signal processing module (12) can determine the torque, pitch, phase angle and rotating speed of the propeller, respectively, based on the long delay, short delay, specific interval and expected delay of the magnetic induction probe (11) response signal. The U-shaped torque teeth and the splayed mark te
