基于单片机的火车道口安全报警的讨论与设计电子信息工程专业 [摘 要]道口是铁路安全运输问题的重点和薄弱点。本课题针对我国铁路平交道口的现状，利用单片机技术开发了平交道口来车自动报警系统，采纳了可靠性高、价位低、普及程度高、利于基层技术人员掌握学习的 89C51 作为控制芯片，利用了轨道传感器采集回来的车轮信息，准确地将来车信息通知道口值守人员及过往行人，大大减少了事故发生的隐患。针对系统工作环境的恶劣和工作的特别性，在系统硬件设计过程中，重点突出了系统运行的可靠性、设备的坚固程度，在软件的编制上也实行了有力的抗干扰措施，因此，本系统的讨论与设计具有重要的社会意义以及推广价值。[关键词] 运输安全；铁路平交道口；单片机The Research and Design Based on The Single-chip Computer for The Rail-road Crossing Warning SystemElectronic Information Engineering TANG Li-junAbstract: The Level road crossing is emphasis and weak point.This article discusses the present situation of our rail level road crossing,use single-chip microcomputer system to design the coming vehicle automatic warning system for level road crossing.The core chip is 89C51 which has high reliability,low price and good universality.Most technicians can master it easily.The system gets the coming vehicles message,and gives notice to the crossing keeper and the people.So it can reduce the hidden dangers and provide the insurance for the rail traffic. Because of the bad running environment and working important,so we think much of the system running reliability,firmness of device.Some measures also are taken in the software. So the research and design of this system is very necessary.Key words：Traffic Safety; Rail-way Crossing; 89C51毕业论文（设计）诚信声明本人声明：所呈交的毕业论文（设计）是在导师指导下进行的讨论工作及取得的讨论成果，论文中引用他人的文献、数据、图表、资料均已作明确标注，论文中的结论和成果为本人独立完成，真实可靠，不包含他人成果及已获得 或其他教育机构的学位或证书...
