摘要
根据题目要求,本设计采用2片AT89C52单片机构成主从式的控制系统,双机采用串行口进行通信。红外遥控部分采用遥控车模专用编、解码芯片TX-2/RX-2,提高控制的可靠性;同时,在遥控发射端加入了用凌阳61板做的语音识别系统,能够完成语音遥控功能。采用红外传感器进行里程检测;超声波传感器进行障碍识别;感光电阻辅以步进电机控制的转动机构进行光源方向的检测,并能用软件控制小车行驶到光源附近。采用步进电机对小车的转向进行精确的控制,同时用红外传感器对转向的角度进行校正。此外,采用四位LED数码管和若干LED发光二极管显示时间、行进的里程以及小车的各种状态;采用AT24C08串行EEPROM记录小车的行驶轨迹,并能按照所记录的轨迹自动行驶。
本次设计基于完备的软硬件系统,很好的实现了小车语音遥控、任意曲线行驶、路线记录与重放、自动查找光源、自动避障,里程统计并发出指示信息等功能。

ABSTRACT
According to the topic, my design needs to adopt two AT89C52 to form a control system of principal and subordinate. munication between the two MCU is to adopt the serial port. Meanwhile, launch end join with insult male genital 61 sound recognition system that board make remotely, can finish the remote control function of the pronunciation, and it adopts the infrared sensor to measure the mileage; The ultrasonic sensor carries on the obstacle to discern; Sensitization plement in order to walk into whom electrical machinery control anization carry on measuring, direction of the light source, The small car can go to the adjacent place of the light source with the software .The design adopts serial EEPROM of AT24C08 to write down the orbit of the car , and can repeat the route automatically which has been recorded.
The Design is on the basis of plete software and hardware system, and the small car has the function of sound remote control, following any curve, recording the route where it has gone, finding out the light source, etc…
