摘要
设计了一种基于超声波测距原理的倒车雷达系统,给出了声光报警模块、电源模块、人机交互模块的具体实施方案。此外,设计中还包括温度自动校正功能,以减小由于声速受到温度影响而引入的测量误差。实际测试结果表明,有效测距范围在0.05～5.7m,5m以内的最大误差不超过0.01m。
In this paper, reversing radar system was introduced based on new high-performance, low-power microcontroller ATmegal6, and the reversing radar software and hardware implementations and real-time ranging implementation process was given. Advantage of this system was less external components, low cost, high precision, easy to upgrade, experimental results fully meet the actual needs.
