摘　　要：为了在有毒、辐射、烟雾、高温高压场合中探测、采集环境参数,以AT89S52单片机作为控制核心,HC-SR04超声波传感器测速,红外管RPR220作为循迹传感器,设计了一种多功能探测小车,单片机AT89C52根据红外管检测的轨迹信号产生的PWM波驱动模块L298N来控制小车的速度和转向,并在小车上预置三路传感器接口来检测环境参数,无线模块PTR2000将检测到数据传回路由协调器后送PC。测试结果表明:小车可沿着预置"S"行驶,小车无线数据传输距离达280m。In order to toxic, radiation, smoke, high temperature and high pressure situations in the detection, collection of environmental parameters, system with AT89S52 single chip as the control core, HC-SR04 ultrasonic sensor measurement, infrared tube RPR220 as a tracking sensor, the design of a multifunctional detecting car, MCU AT89C52 according to the track signal detecting infrared tube generated PWM wave driving module L298N control the speed of the car and turn on the trolley, and preset three sensor interface to detect environmental parameters, PTR2000 wireless module will detect the data back to the routing coordinator PC machine. The test result of the system： the vehicle along the preset ＂S＂ car driving, wireless data transmission distance up to 280 meters.
