摘要
基于电子移位逐行红外线扫描和超声波测距技术,设计出一种汽车定位系统,并给出硬件电路和软件设计方案。该系统采用内置接收头和动态红外线发射等方法消除室外强红外线干扰,以延时中断解决测距盲区问题,并用软件控制定位速度和扫描强度。现场测试结果表明,该系统能全天候工作,满足了汽车定位的速度和精度要求。
Based on electronic shift progressive infrared scanning and ultrasonic distance measurement technology,a new automobile positioning system including circuit and software had been designed.Built-in infrared receiver and dynamic infrared emission method was used to eliminate outdoor strong infrared jamming.The ranging blind spot question was solved by delayed interruption.The positioning speed and the scanning intensity were controlled by software.The scene experimental results indicated that the system could work in all weather conditions and met the speed and accuracy requirements for automobile positioning.
