【Abstract】 A micro-motion working table system of displacement measuring and servo-controlling based on MCU is designed.The single-chip is used for controlling movement of the working table,controlling of the keyboard and display.The signal processing circuit samples the signal passed by grating displacement sensor,deals with it by amplifying,filtering and subdividing,and then switches it to a series of pulses which are sent to the single-chip.By I / O port,the single-chip sends the pulse signal and the direction controlling signal to make the step-servo motor turn.The working table brings along the grating displacement sensor moving,and meanwhile,the displacement is measured by the sensor.更多还原
