基于北斗卫星定位的预警系统

The early warning system based on Beidou satellite positioningAbstractThe construction of the Beidou system began in 1994,and over the past 20 years,thetechnology has continued to iterate and high-precision satellites have been launched at 19:55on March 19,2020,the 54th positioning satellite arrived in space,and China's Beidoubasically formed a global service capability.The transportation industry is the coreapplication scenario of Beidou system at the public level.Due to the early completion of thesystem,the application of Beidou system in this aspect is not yet mature,but it can beexpected that the Beidou system will bring us a substantial reduction in the traffic accidentrate and orderly transportation lines with dense network.The early warning system based on Beidou satellite positioning is designed to furtherexplore the great potential of China's Beidou system in the road transport industry.Thisgraduation design is based on the basic knowledge of the STM32 and beidou module,on thebasis of simple one-to-one navigation to expand more point early warning,the relativedistance between the point communication using Zigbee wireless transmission,all point byBeidou positioning data to calculate the relative distance,when the relative distance is toolarge by GSM module and light warning,whereby the wild transport rate control in the lowlevel of risk.Keywords:Beidou;GSM;Relative distance;warning
