Abstract

This paper analyzed the principle relative twisting angle with optical fibre minor bend, and obtained a theoretical model on torque measurement of the torque. The problem of power supply and signal transmission is the key in the torque measurement of rotating system. The paper applies high-frequency radio influence power to realize radio power supply, applies DSP processing circuit, digital signal transmission circuit, to realize radio signal transmission, using computer for data processing. The application of loop leakage gap antenna array cable as the measuring carrier of rotating signals in the signal blind zone, continue a new best transmission path for the rotating signals. The results of the experiment show the sensor has a very good prospect of application. And it realizes the power monitoring of a rotating device, and pave the way for the automation and intelligence of the devices.
