摘要：本智能车是以铝合金为车架，AT89S52单片机为控制核心，加以直流电机、舵

机、光电传感器、火焰传感器和电源电路以及其他电路构成。系统由89S52通过IO口控制小车的前进后退以及转向。舵机带动灭火风扇左右转向摆动进行灭火。寻迹由RPR220型光电对管完成，远红外火焰传感器进行火焰扫描。同时本系统用凌阳单片机进行语音的播报，以提示当前状态。本系统同时通过DF无线数据收发模块进行无线数据传输，将该车当前的状态远程传送给显示台。显示台由OCMJ4X8C液晶屏和2个按键进行实时状态显示和启动控制。

Abstract: The smart car is aluminum alloy for the chassis, AT89S52 MCU as its core,

including motor and servo, plus photoelectric sensors, as well as other flame sensor and power circuit. MCU controls the car turning back forward or running on the white line. RPR220 reflective photo sensor seeks the trace. Far infrared flame sensor tracks the flame. In addition, the SCM system with Sunplus for voice broadcast can remind current status. The system transmits information through DF module. The car’s status will be transmitted to the Remote Console. OCMJ4X8C LCD display and 2 keys for start control.
