北京理工大学珠海学院 2020 届本科生毕业设计基于北斗卫星定位的预警系统基于北斗卫星定位的预警系统摘要北斗全体系的建设开始于 1994 年，在 20 年来技术持续迭代、高精度卫星相继升空的背景下，2020 年 3 月 19 日 19 时 55 分，第 54 颗北斗导航定位卫星到达太空，我国北斗基本形成了覆盖全球的服务能力。交通行业是北斗体系在公开层面最核心的应用场景，由于体系初成，我国北斗在部分方面的应用还不成熟，但可以预期北斗系统能带给我们的是交通事故率的大幅度的降低、星罗密布的运输线路变得有条不紊。基于北斗卫星定位的预警系统的设计目的就是为了进一步的探索我国北斗系统在道路运输行业的应用所具有的巨大潜力。本设计基于 STM32 和北斗模块的基本知识，在简单一对一导航的基础上拓展多点位间的相对距离预警，点位间通信采用 Zigbee 无北京理工大学珠海学院 2020 届本科生毕业设计线传输，在相对距离过大时由 GSM 模块和指示灯向用户发出预警，藉此将野外运输的风险率控制在较低水平。关键词： 北斗；GSM；相对距离；预警The early warning system based on Beidou satellite positioningAbstractThe construction of the Beidou system began in 1994, and over the past 20 years, the technology has continued to iterate and high-precision satellites have been launched at 19:55 on March 19, 2020, the 54th positioning satellite arrived in space, and China's Beidou basically formed a global service capability.The transportation industry is the core application scenario of Beidou system at the public level. Due to the early completion of the system, the application of Beidou system in this aspect is not yet mature, but it can be expected that the Beidou system will bring us a substantial reduction in the traffic accident rate and orderly transportation lines with dense network.北京理工大学珠海学院 2020 届本科生毕业设计The early warning system based on Beidou satellite positioning is designed to further explore the great potential of China's Beidou system in the road transport indus...
