Intelligent tracing fire car consists the following eight parts： tracing-module, finding-fire module, speed-detecting module, fire-fighting module, displaying module, car tail light, motor-drivering module and MCU controlling module. By using AT89S52 as the core it control the car to realize the control and communication of each module. This car has a designated routes, according to patrol found on the function of automatic fire extinguishing fire. Tracing some of the reflective optical sensor and the comparator component, the data will be collected after processing feedback to the microcontroller; finding the fire in part by the ADC0809 and the infrared tubes; fire in part by the step-up circuit and fan components; motor will be drived by a L298N core components. The car has a patrol in accordance with designated routes and finds the automatic fire extinguishing function.%智能循迹消防小车由寻迹模块、寻火模块、测速模块、灭火模块、显示模块、车尾灯、电机驱动模块以及MCU控制模块等八大部分构成。采用爱特梅尔半导体公司的AT89S52作为小车的控制核心,实现对各个模块的通讯和控制。寻迹部分以反射式光电传感器和比较器组成,将采集到的数据处理后反馈至单片机;寻火部分由ADC0809与红外对管组成;灭火部分由升压电路和风扇组成;电机由以L298N为核心部件的电路驱动。该小车具有按照指定的路线巡逻,发现火源进行自动灭火的功能。
