I摘要当今时代，经济的快速发展提高了人民生活水平，汽车成为日常生活中必需的代步工具。汽车数量的增多导致了各种交通事故。保持汽车行车的安全距离是避免交通事故的有效手段。因此本系统设计了一款汽车行车安全距离监测系统。本次设计的汽车行车安全距离监控系统主要是以 STC89C52 为主要核心，整合其他硬件设施，实现单片机通过超声波测距模块测得距离，将距离显示在屏幕上。用户可以通过按键设置安全距离阈值，一旦实测距离小于了预设阈值，那么系统就会驱动报警，提醒安全行车。这次设计是将高精尖技术生活化的一次尝试，在整个作品的设计、制作、调试过程中，对单片机又有了进一步的理解，对超声波测距、蜂鸣器等也有了更深入的了解。经过调试本系统具有较好的实用性，可以满足实际需求。关键词: 汽车行车安全距离；单片机；超声波测距；报警IIABSTRACTNowadays, with the rapid development of economy, people's living standard has been improved. The increase in the number of cars leads to all kinds of traffic accidents. Keeping a safe distance is an effective way to avoid traffic accidents. So this systemThe design of the vehicle safety distance monitoring system is mainly based on STC89C52 as the main core, the integration of other hardware facilities, the realization of single chip microcomputer through the ultrasonic ranging module measured distance, distance display on the screen. Users can set the safe distance threshold by pressing the button. Once the measured distance is less than the preset threshold, the system will drive an alarm to remind safe driving. This design is an attempt to turn the high-precision technology into life. In the design, production and debugging process of the whole work, I have a further understanding of the single-chip microcomputer and have a deeper understanding of ultrasonic ranging and buzzer. After debugging the system has good practicability, can meet the actual needs.Key words: safe driving distance; Single c...
