智能电动多功能服务小车的设计与实现

Design and Implementation of Intelligent Electric Multi-function Service Car

当今社会老龄化日趋严重,大量留守老人独自在家,无法独自搬运物体,给生活带来不便,本文以此为背景,设计一款智能电动多功能服务小车。本文首先对推车的历史、发展趋势和特点进行了阐述,在此基础上对系统进行了硬件设计,主控器选用含有ATMEGA2560-16AU控制器的MegaPi Pro控制板,运动控制部分选用37mm、12V/200RPM的直流电机和配套的驱动器,图像采集模块选用500W像素的OV5640型号的摄像头,定位模块选用WF-NEO-6M模块和配套的SMA GPS天线。软件上,通过mBlock图形化编程软件对小车运动控制进行编程,同时通过Keil软件对摄像头采集图像和GPS定位模块进行了程序的编写。在硬件和软件完成的基础上,对实物进行了运行调试,最终实现了小车的运动、图像采集和GPS定位等功能。

Nowadays,with the aging of society becoming more and more serious,a large number of Left-behind elderly people are at home alone,unable to carry objects alone,which brings inconvenience to life.Based on this background,this paper designs an intelligent electric multi-functional service car.Firstly,the history,development trend and characteristics of the cart are described.On this basis,the hardware design of the system is carried out.MegaPi Pro control board with ATMEGA2560-16 AU controller is selected as the main controller,37 mm,12 V/200 RPM DC motor and matching driver are selected as the motion control part,500 W pixel OV5640 camera is selected as the image acquisition module,and positioning module is selected as the positioning module.WF-NEO-6 M module and matching SMA GPS antenna are used.In software,the car motion control is programmed by mBlock graphical programming software,and the camera image acquisition and GPS positioning module are programmed by Keil software.On the basis of the completion of hardware and software,the object is debugged and the functions of motion,image acquisition and GPS positioning of the car are finally realized.
