基于ARM7及nRF905的智能小车系统设计

研究设计了一种基于ARM处理器声音导引系统控制的智能小车设计方案,包括系统组成、工作原理、硬件搭建、软件设计及系统测试等。智能控制系统利用音频为媒介,通过nRF905无线模块发射与接收音频信号,利用ARM7芯片处理音频信号时间差,计算出目的地和小车当前位置相对位置;最后ARM7发出控制指令,控制小车驱动,引导小车向目标移动。小车移动过程中,ARM7根据无线模块接收的实时音频信号,不断修正控制参数,直至到达目标位置。

Design of intelligent car system based on ARM7 and nRF905

Designing strategy of an intelligent car controlled by voice is worked out,including the system formation,the principle of work,the construction of hardware,the designing of the software and the testing of the system.Voice controlling system is to transmit and receive signals by using frequency as media and the wireless module of nRF905,to locate and amend the mistakes and to guide the car to the target position.The focus and tough points are as follows: ASSP chips controlled by electric motor;the processing of voice frequency signal;the figuring of the target position.
