教学单位 信息工程系 学生学号 2061224236 孝感学院新技术学院 本科毕业论文(设计) 题 目 基于单片机STC89C52控制的智能小车 学生姓名 张 婷 专业名称 电子信息科学与技术 指导教师 丁么明 教师职称 教 授 2009年12月12日基于单片机STC89C52控制的智能小车 摘要：该毕业设计是采用无线遥控基于单片机的功能实现的，当无线遥控器的某个按键按下时，无线发射器将按键信号以编码的形式在315MHz的频率上发射出去，无线接收器接收并放大发射信号同时解调出TTL电平信号送至单片机进行处理，单片机通过比较和识别接收来的无线遥控编码便可执行相应的遥控功能，从而实现智能小车的前进、后退、左转和右转的基本功能和伴随音乐演奏而闪烁的LED的开启与关闭的功能。此外，我加入了温度传感器与时钟芯片，让它们在液晶显示器上显示其室温和时间，并用按钮进行时间的调控。由于无线遥控模块是四路单向锁存模块，只能单线实现四个功能，所以发射模块的控制按键不够，根据需要，我仅仅用无线模块控制小车的前进和后退，停止，其它的采用按键调试，用按键来实现小车的前进/后退/左转/右转/音乐/时间调控等功能。 关键词：无线模块；液晶显示模块；电机驱动模块；音乐；智能小车 The intelligent telecontrol minicab based on PIC STC89C52 Abstract：This graduate design adopts wireless remote on the basis of one chip computer function to realize. When one of the buttons of the wireless telecontroller is pressed, the wireless transmitter transmits keypad singles at 315MHz in the way of encoding. The wireless receiver receives and amplifies transmitting singles and demodulates TTL singles and sends the TTL singles into PIC for tackling. The PIC conducts the corresponding telecontrol functions by comparing and recognizing the wireless telecontrol code which has been received, so that it realizes the basic functions of the minicab’s advance、stepping back、acceleration、deceleration and the function of the flickering LEDs turning on and off with the music. Besides，I add the temperature sensor and clock chip additional to make them display room-temperature and time in the LCD and manipulate them with the buttons. As a result of wireless remote Module is four ways of saving module only realize four functions on single line. So launch module of control button is not enough. According to need, I only use wireless module control advance、retreat and stop. About button debug, it use button come to realize the function of advance、retreat、turn left、turn right、music and regulate of time and so on.
