| Abstract: | Design a system module of digital detecting minute displacement based on CPLD and length gauge.Incremental length gauge is used to be the sensor of measuring minute displacement.CPLD deals with the real time signal processing.The software compiled in CPLD will transform the incremental pulse signal to displacement quantity,and send the displacement quantity to main CPU by data BUS.Arithmetic of software will include the estimate and filter the disturb and how to count the minute displacement. |
