| Abstract: | Measuring Principle of Grating sensor was stated in the paper,by using the characteristics of precise measurement of grating,We developed Wheel hub measurement device.Grating sensor is used to Sample shift signal.Morie fringes of grating and photo-electricity conversion principle were adopted to convert measured displacement to digital pulse signal to output.In order to improve precision measurement and realize the signal direction recognition,it adopts pulse direction recognition and quadruplex circuit.Thus Digital data display of the pulse signal through single-chip computer control program. |
