基于FPGA的智能小车设计

摘要

介绍基于FPGA的智能小车设计,小车包括在FPGA上构建以NiosⅡ嵌入式系统为核心的控制电路、传感器电路、动力及转向电路、LCM电路、温度和湿度测量电路、无线数据收发电路.在Nios Ⅱ集成开发环境(IDE)编写C语言程序,实现能远程遥控小车、自动避障、温度和湿度监测并无线传输至控制端的功能,其特点是能够无线控制小车和远程采集环境信息.%A way to devise an intelligent car based on FPGA is introduced.Nios Ⅱ embedded system taken as central control circuit, sencor circuit, LCM display circuit, temperature and humidity measuring circuit, and wireless data transceiving circuit is built with FPGA in the intteligent car.The C language program is written in Nios Ⅱ integrated development environment (IDE) to realize the car's functions of remote control, automatic avoidance of roadblocks, humidity/temperature monitoring, and data wireless transmission to the controller.Moreover, the highlight of this design is that the car can acquire environmental information remotely and transmit it to the controller wirelessly.
