基于89C52单片机的遥控电动小车控制系统设计

遥控电动小车系统以89C52单片机为核心控制器，包含了主控制器模块、电机驱动模块、液晶显示模块、键盘模块、测距模块、蓝牙通信模块、电源模块等。进而设计制作出一台具有自动运行的智能小车控制系统。本系统以两个步进电机作为驱动，通过各类传感器件来采集各类信息，通过2．4GHz蓝牙通信模块实现小车在手持无线遥控器的控制下前进、转向、倒退、小车精确转弯、自动定位等功能。智能小车系统具有很高的灵敏度和精确度，操控简单、便捷。

The Design of Remote Control Electric Car Control System Based on Bluetooth and 89C52 MCU

The remote control electric car system with 89C52 as the core controller, consists of main controller module, motor drive module, LCD module, keyboard module, ranging module, Bluetooth communication module, power module, etc. On this basis, an intelligent car control system is designed. This system adopts two stepper motors as the drive, uses various kinds of sensor to collect all kinds of information, and utilizes the 2.4 GHz Bluetooth communication module to achieve the forwarding, back-warding, returning, automatically turning and positioning of the car under the control of handhold wireless remote controller. The intelligent car system has high sensitivity and accuracy, and its manipulation is simple and convenient.
