基于单片机和蓝牙的避障小车控制系统

摘要随着时代的迅速发展，科技不断的发达，各类电子消费产品越来越呈现智能化和小型化的趋势。各种智能基于单片机和蓝牙的避障小车在电子市场占很大的比例。美国智能基于单片机和蓝牙的避障小车协会曾经做了一项调查，以前的传统智能基于单片机和蓝牙的避障小车渐渐的在我们生活中消失，而智能基于单片机和蓝牙的避障小车的智能化也慢慢的走进我们生活当中，使得智能化智能基于单片机和蓝牙的避障小车销售量紧追GDP的增长，也就是说智能基于单片机和蓝牙的避障小车的智能化得到更多人的认可。基于上述的背景，本次论文中设计了一款基于STM32单片机和蓝牙的避障小车控制系统，小车和控制终端能通过无线信号互相连接，可以从终端发送指令控制小车。同时还可以通过温度传感器、湿度传感器、烟雾传感器、火焰传感器采集环境指标，采集的模拟量通过模数转换后送到主控电路。用户可以远程控制指令给小车，从而控制小车进行前进、后退、左转和右转的基本移动功能。温度、烟雾浓度、以及火焰的数据能通过APP在手机上能够实时显示出来。用A1tiumDesignerl6画出PCB图，并制作出相对应的实物电路板，然后根据实际情况焊接元器件，用Kei1 uvision软件编译程序，调试完成实物。同时，在Proteus环境下仿真测试，仿真结果表明，本次设计的系统效果很好。本设计充分利用了单片机和故模块之间的相互配合，整体上实现了任务书中所规定的目标，可以实现各种控制模式之间的相互转换，可是实现完全的自动控制和定时控制等相关功能。关键词：STM32单片机探测小车：指令控制：避障：软件系统：硬件系统ABSTRACTWith the rapid development of the times and the continuous development ofscience and technology,all kinds of electronic consumer products are increasinglyshowing the trend of intelligence and miniaturization.Various intelligent single-chipmicrocomputer and Bluetooth obstacle avoidance cars account for a large proportionof the electronics market.The American intelligent single-chip microcomputer andBluetooth obstacle avoidance car association has done a survey,the previoustraditional intelligent single-chip microcomputer and Bluetooth obstacle avoidancecar gradually disappeared in our lives,and the intelligence of intelligent single-chipmicrocomputer and Bluetooth obstacle avoidance car has slowly entered our lives,sothat intelligent intelligent single-chip microcomputer and Bluetooth based obstacleavoidance car sales closely catch up with GDP growth,that is to say,intelligentsingle-chip microcomputer and Bluetooth obstacle avoidance car intelligence hasbeen recognized by more people.Based on the above background,this paper designs an obstacle avoidance trolleycontrol system based on STM32 single-chip microcomputer and Bluetooth,and thetrolley and control terminal can be connected to each other through wireless signals,and commands can be sent from the terminal to control the trolley.At the same time,environmental indicators can be collected through temperature sensors,humiditysensors,smoke sensors,and flame sensors,and the collected analog quantities are sentto the main control circuit through analog-to-digital conversion.The user canremotely control the command to the trolley,thereby controlling the basic movementfunctions of the trolley to carry out forward,backward,left and right turns.Data ontemperature,smoke concentration,and flame can be displayed in real time on mobilephones through the APP.Use Altium Designer16 to draw a PCB diagram,and makethe corresponding physical circuit board,and then solder the components according tothe actual situation,compile the program with Keil uvision software,and debug thephysical object.At the same time,the simulation test in the Proteus environmentshows that the system designed this time works very well.This design makes full useof the cooperation between the single-chip microcomputer and the module,andachieves the goals specified in the missio
