基于WIFI智能车远程测距装置结构设计与研究

Design and Research on WIFI Smart Car Remote Distance Measurement Device Structure

摘要：针对目前普通测距装置无法实现多方位、多角度测量；本论文主要目的是介绍一款基于WIFI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；它可以提供2cm---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WIFI远程控制智能车进行精确的测距；另外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住机（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。

The ordinary distance measuring device can not achieve a multi - faceted, multi - angle measurement. This thesis main purpose introduces a WIFI smart car remote -based distance measuring devices. Design the over- all structure of hardware and programs. Elaborating the design ideas of software and the property of distance meas- uring device, the distance measuring apparatus using an ultrasonic sensor which can provide the non - contact type distance of 2era-400cm sensing function, the ranging accuracy can reach 3cm, Compared with ordinary ranging device, the device can be controlled remotely via WIFI smart car precise ranging, in addition, smart car smart car in the process of moving the code channel is not required. Capture images using camera control signals to the com- puter. The experimental results demonstrate that the device have the feature of strong anti - interference, small steady - state error and etc,
