中文摘要：

智能小车可适应复杂恶劣的环境,进入人无法进入的环境中完成探测任务,应用前景非常广泛。智能小车的设计涉及到电路设计、程序设计、传感器原理、控制技术等诸多方面。文章主要说明基于STC89C52单片机的智能环境探测小车设计。利用火焰传感器自动探测火源,单片机输出PWM波控制直流电机对小车进行驱动,经自动避障后到达起火点,检测并显示火场烟雾浓度,达到探测火场环境的目的。也可根据具体需要,利用红外遥控对小车进行远程控制。

英文摘要：

The intelligent vehicle that can be widely applied in the future is one kind of intelligent robots, which can fit the intricate and terrible situation well and get into some inaccessible environment to complete its mission of detecting. its design largely refers to the circuit,the program, the theory of sensor, manipulative technique, etc. the thesis is to illustrate the designing of the intelligent vehicle based on the SCM of STC89C5 C.The flame sensor firstly detect the originate fire by flame sensor automatically and then the SCM can output PWM wave to drive the vehicle by curbing the continuous current dynamo. After arriving at the destination on fire via avoiding obstacles, the vehicle can detect and display the smoke concentration so that the state on fire can be detected. Also, the vehicle can be remotely curbed by infrared remote control according to the specific requirement.
