Abstract

The grating digital readout is the key measurement feedback device of the numerical control system and base of the equipment manufacturing industry. With the development of the complex machining, the multi-axis linkage is a new direction of the numerical control system, which needs the multidimensional measurement. Based on all digital grating moiré fringe subdivision theory, the paper introduces the design of integrated and networked multidimensional grating digital readout with an embedded system-on-chip ZA7V that is a complete field configurable system-on-chip with a 32- bit ARM7TDMI processor core, a programmable logic matrix, a robust memory subsystem and a high-performance dedicated internal bus. Networked functions include Ethernet interface, CAN bus interface, USB bus interface and GPRS interface so that the grating digital readout can access the device network, workshop network, intranet network and Internet. The simulation results and experimental data prove that the realization of the integrated and networked multidimensional grating digital readout. It will be widely used in the numerical control system and machining center.
