摘　　要：以单片机为核心控制器件,设计了一种蓝牙遥控小车系统。针对小车的信息采集、驱动及调速等问题,采用Eclipse开发环境辅助Arduino编程,并通过串口仿真实现手机蓝牙客户端与车上蓝牙模块服务端的通信。单片机驱动L298N控制小车运动,用双极式H型可逆PWM变换器进行调速,小车安装高清摄像头无线返回实时信息。系统电路结构简单、可靠性高、软硬件完备,且可按照预先设定的模式在规定环境内自动运作。A small trolley system based on Bluetooth chip is designed with an MCU as the control core. Eclipse and Arduino programming is used for information collection, driver and speed control, and the communication between Bluetooth mobile client-side and Bluetooth ear server-side is realized via serial port emulator. The movement of car is controlled by Driver L298N, and the speed by the bipolar type H reversible PWM converter. The HD camera installed in the car sends back real-time video and pictures by wireless transmission. The whole system is simple in circuit structure and reliable in performance is high with a complete software and hardware. It can operate automatically in pre-set modes in an environment, making it suitable for scientific exploration.
