基于FPGA的激光测距控制系统设计

Design of Laser Distance Measurement Control System Based On the FPGA

本文介绍一种基于FPGA和ARM9的激光测距系统的硬件原理设计和软件设计方案。该方案采用SICK公司的户外型激光传感器LMS221,和ALTERA公司cyclone系列的EP1C12Q240I7FPGA芯片。控制系统采用ARM+FPGA的结构,系统运行嵌入式Linux操作系统,从而保证系统可以灵活的实现高速数据采集和实时数据传输。

This paper covers the design of circuit principle and software design of laser distance measurement system which is based on FPGA and ARM9. In the design the LMS221 outdoor laser sensor from SICK and FPGA EP1C12Q24017 of cyclone from ALTERA are used. The design uses ARM＋FPGA system and embedded Linux operating system which could flexibly realize high speed data acquisition and real-time transmission.
