为实现对多路光栅数据进行高速采集以及远程传输,设计了基于FPGA+ARM架构的光栅数据采集系统。该系统以现场可编程逻辑门阵列(FPGA)实现对多路光栅数据同时进行高速采集、存储和传输,以ARM微处理器为核心,实现数据处理和以太网传输功能,通过对以太网协议栈的移植,实现了与PC端以TCP/IP协议完成以太网通信。通过实验验证,证明该系统具有良好的准确性和稳定性,可以满足光栅数据采集及传输的要求。

In order to realize high-speed acquisition and remote transmission of multiplex grating data,a grating data acquisition system based on FPGA+ARM architecture was designed.This system uses field programmable logic gate array(FPGA)to realize high-speed acquisition,storage and transmission of multiplex grating data at the same time.It takes ARM microprocessor as the core to realize data processing and Ethernet transmission functions.Through the transplantation of Ethernet protocol stack,it realizes Ethernet communication with PC terminal via TCP/IP protocol.Experiments show that the system has good accuracy and stability,and can meet the requirements of raster data acquisition and transmission.
