基于MK60DN512单片机的汽车跟车预警系统设计

基于MK60DN512单片机的汽车跟车预警系统装置包括激光测距传感器、旋转编码器、蜂鸣器、一个三位开关、LM2940芯片、红色LED灯、黄色LED灯、绿色LED灯以及MK60DN512单片机。本次设计汽车跟车预警系统,通过在汽车前测安装激光测距传感器,在后轮上安装旋转编码器,将采集到的距离信号和速度信号传递给单片机,单片机进行处理分析后通过蜂鸣器和不同颜色的LED灯给予驾驶员相应的提示和预警,通过三位开关可以在晴天、雨天和雪天三种模式下进行选择。本设计所述方法,能够自动检测跟车环境是否安全,并在环境危险时给予预警,在绝对安全时提示允许加速,提高了汽车跟车行驶的安全性。

Design of Early Warning System for Car Following Based on MK60DN512 MCU

The early warning system for car following based on MK60DN512 microcontroller includes laser ranging sensor, rotary encoder, buzzer, three-position switch, LM2940 chip, red LED lamp, yellow LED lamp, green LED lamp and MK60DN512 microcontroller. This design of car-following early warning system, through the installation of laser ranging sensor in front of the car, rotary encoder on the rear wheel, will collect the distance signal and speed signal to the MCU, MCU processing and analysis, through buzzer and different colors of LED lights to give drivers the corresponding prompt and early warning, through three switches can be in sunny, rainy and snow days. Choose in three modes. The method described in this design can automatically detect whether the car-following environment is safe or not, give early warning when the environment is dangerous, prompt for acceleration when absolutely safe, and improve the safety of car-following.
