摘要
介绍了一种依据蚁群通信原理实现的高速公路汽车追尾碰撞预警系统。车载无线信息收发单元以AT89S8252单片机为控制器,采用Motorola InstantGPS芯片获得汽车运行的位置和速度信息,使用无线数传芯片nRF905与邻近汽车交换各自的数据,实时计算本车与前方邻车的间距,在出现危险倾向时发出报警。
A kind of automobile rear-end early warning system was introduced, which is based on Ant Colony communication principle. AT89S8252 SCM acts as controller in the car-carried wireless cell. It acquires automobile＇ s position and speed information by Motorola Instant GPS, and exchanges data with other cars nearly by transceiver nRF905, then calculates the distance from itself to the front one. It gives an alarm in times of crisis.
