Based on photoelectric convert and transferring torque measurement principles

a embedded torque measurement system based on photo-electricity multiple code-tracks technology is designed.This system uses multiple cycles photo-electricity coder which is discrete phases for addition the number of the measurement points

increases the accuracy of torque measurement.And the embedded structure makes the hardware circuit and software program more easy and intelligent

implement of the torque real-time measurement

furthermore transferred to the host computer display

storage and data processing.Experimental results show that the system has lower cost

higher accuracy and better reliability.
