针对交通运输、交通工程专业的单片机原理及接口技术课程实验教学现状,设计了一个智能交通工程领域的综合性实验系统。该系统以STC89C52单片机为核心,使用红外光电传感器采集客车上下车人数并实时显示在中文液晶屏上,当客车发生超载情况时,通过中国移动通信网络向管辖交警无线发送预警短信,并在客车现场进行语音提示司机。通过该实验学生能够很好的学习单片机软硬件设计并应用于所学交通运输专业场合,达到了以应用型为目标的实验教学。
Aiming at experimental teaching of single-chip microcomputer principle and interface technology course for transportation and traffic engineering, a comprehensive experimental system in the field of intelligent traffic engineering is designed. The system is based on STC89C52 microcontroller, and use infrared photoelectric sensors to collect number of people getting on and off and display on the LCD screen in real time, when it is detected that the bus is overloaded, the system sends a warning SMS to the traffic police remotely through the GSM network, and at the same time, voice prompt driver at the bus site. Through the experimental design, the students can learn the software and hardware design of the single-chip microcomputer and apply it to the professional transportation occasions, and achieve the experimental teaching with the application type as the goal.
