基于Wi-Fi智能车远程测距装置结构设计与研究

Design and Research on Wi-Fi Smart Car Remote Distance Measurement Device Structure

介绍一款基于Wi—Fi智能车远程测距装置，设计了总体的硬件结构和方案，阐述了该测距装置的工作性能和软件设计思路。该测距装置采用远程数据传输和超声波传感器测距的方法，可以提供2—400cm的非接触式距离感测功能，测距精度可以达到3cm。与普通的测距装置相对比，该装置的特别之处是可以通过Wi—Fi远程控制智能车进行精确测距。智能车在行驶的过程中跟以往的智能车不同的是不需要码道，而是采用摄像头云台采集图像信号给上位机（计算机）进行控制。实验结果显示该装置具备抗干扰性强、稳态误差小等特点。

This thesis main purpose introduces a Wi - Fi smart car remote-based distance measuring devices. Design the overall structure of hardware and programs. Elaborating the design ideas of software and the property of distance measuring device, the distance measuring apparatus using an ultrasonic sensor which can provide the noncontact type distance of 2 - 400 cm sensing function, the ranging device, the device can be controlled remotely via smart car in the process of moving the code channel is not computer. The experimental results demonstrate that the steady-state error and also. ranging accuracy can reach 3 cm. Compared with ordinary Wi - Fi smart car precise ranging, in addition, smart car required. Capture images device have the feature using camera control signals of strong anti-interference, to the small
