| Abstract: | The working principle of incremental time-grating displacement sensor is introduced. Based on the analysis of signal produced and incremental measuring method, the circuit module for defending from repeating count is designed by using D trigget principle, and the circuit module for producing incremental signals and direction signals is designed by VHDL, sothat the issue of increment signal processing circuit is solved. The correctness of circuit design is validated with sequential simulation. The programmable feature of CPLD makes circuit upgrade convenient. |
