摘　　要：山区道路地貌条件复杂多变,道路狭长、弯多、斜坡陡,再加上道路视距差等原因,山区道路行车风险大,安全性要求高,设计一款用于山区弯道检测预警的交通系统尤为重要。当车辆进入弯道时,山区弯道检测预警系统能够进行实时监测,并通过控制红绿灯指挥车辆通行或等待。弯道中的屏幕上通过提示对向来车行车距离,来缓解司机对前面交通状况还没有充分认识的问题,用不同状态图片显示的方式告知驾驶员此时弯道的行车状况。山区弯道会车检测预警系统采用STM32单片机为核心进行数据转换与分析,采用太阳能进行辅助供电,以达到节能的目的。结合当下,社会对山区弯道交通设施的研究和建设还比较少,因此具有较高的价值。经过实验调试与测试,系统运行稳定,信号采集和输出正常,交通指挥精准,达到设计任务要求。Mountain road physiognomy condition is complex and changeable,the road is long and narrow,many bends,steep slope,coupled with the road visual distance difference and other reasons,mountain road driving risk,high safety requirements.It is particularly important to design a traffic system for detecting and warning curves in mountainous areas.When the vehicle enters the curve,the mountain curve vehicle detection and early warning system can carry out real-time monitoring,and through the control of traffic lights to direct the vehicle to pass or wait.Corner of the screen by prompt has always been the driving distance,to ease the driver in front of the traffic has not yet fully understand the problem,in a different state images show the way to inform the driver turns driving conditions,at this time passing each other mountainous corner detection warning system uses STM32 MCU as the core,data transfer and analysis using auxiliary power supply of solar energy,in order to achieve the purpose of energy saving.Combined with the current,social research and construction of mountain bend traffic facilities is still relatively little,so it has a high value.After the final detection,the system runs stably and normally,the signal acquisition and output are normal,the traffic command is accurate,and the requirements of this design are met.
