基于STM32的可遥控自动跟随小车

基于STM32的可遥控自动跟随小车设计摘要随着智能技术在各行业得到了广泛的应用和研究，各种功能的智能小车系统在针对不同领域不同需求的功能划分也越来越明确。在小区快递站环境中往往存在无配送人员配送上门，老人等弱势人群无能力取件的情况。传统物流人员运力不足，针对这种应用场景下的智能小车系统，本课题设计了一种基于STM32的可遥控自动跟随小车主要完成了硬件平台搭建和软件层面设计两个方面的工作。论文工作的硬件平台采用STM32F103RCT6开发板，在遥控模式下，选择了HX1838通过红外遥控器实现对小车移动控制，在跟随模式下，使用HX711检测物品重量，HCS04获取数据。电源方面选择了便宜耐用的18650电池盒，该电池轻盈，便捷，易更换。在软件设计方面在Keil5的基础上完成了各个模块的驱动开发。通过显示模块观察数据，红外遥控实现对小车的控制，超声波检测跟随目标物体。关键词STM32F103RCT6:红外遥控：超声波检测：压力传感器检测：Design of a remote-controlled automaticfollowing car based on STM32AbstractWith the widespread application and research of intelligent technologyin various industries,intelligent cart systems with various functions are increasingly clearly divided into functions with different needs in differentfields.In the environment of regional express delivery stations,there areusually situations where there are no delivery personnel delivering goods to the doorstep,and elderly and other vulnerable groups are unable to pick up the goods.The traditional logistics personnel have insufficient capabilities.In order to cope with the application scenario of this intelligent carsystem,this topic designs a remote-control automatic tracking car basedon STM32,mainly completing the hardware platform construction and software level design in two aspects of work.The hardware platform for thepaperwork uses the STM32F103RCT6 development board.In remote control mode,HX1838 is selected to achieve bracket motion control through infrared remote control.In tracking mode,HX711 and HC-SR04 are usedto detect the weight of items to obtain data.In terms of power supply,choose the 18650-battery pack that is cheap,durable,lightweight,practical,and easy to replace.In terms of software design,the development of different modules is based on Keil5.By observing the data through the display module,the infrared remote control allows for controlling the car andtracking the target object through ultrasonic detection.Keywords STM32F103RCT6,infrared remote control,ultrasonic detection,pressure sensor detection目录摘要」......IAbstract..Ⅱ第1章绪论1.1课堂的背景及意义1.2国内外发展现状21.2.1国内发展现状.21.2.2国外发展现状31.3本文主要研究内容4第2章可遥控自动跟随小车系统总体方案设计62.1系统总体方案设计62.2系统关键器件选型72.2.1主控芯片的选型.72.2.2超声波模块选型.92.2.3压力传感器选型.102.2.4电机驱动选型.112.3本章小结.….12第3章可遥控自动跟随小车系统硬件设计.133.1硬件总体设计方案.133.2STM32F103RCT6最小系统电路133.2.1STM32F103RCT6芯片…143.2.2时钟电路….153.2.3复位电路153.2.4电源电路.163.2.5CH340串口电路.163.3超声波模块设计..173.4红外遥控模块设计.….183.5压力传感器模块设计…..193.6显示模块设计.193.7电机驱动模块设计213.8人体检测模块设计..223.9本章小结..22第4章可遥控自动跟随小车系统软件设计234.1软件设计语言与开发环境.234.2主程序设计.244.3子程序设计…27
