摘要
设计了一种基于RFID(无线射频识别)和卫星导航技术的车距监测预警系统。系统通过卫星导航芯片获取车辆精确的地理信息,采用nRF2401射频模块实现车辆之间的相互通信,应用凌阳单片机实现车距的快速精确计算和系统控制。系统能够为高速行驶的汽车提供实时的周边车辆车距信息,并及时提供车距预警。经过测试,本系统应用高效可靠,可有效预防恶性交通事故的发生。
A distance-oriented car monitoring and warning system based on RFID and satellite navigation technology is designed.The system can obtain the precise geographic information of cars through the satellite navigation chip,apply nRF2401 module to realize the communication among cars,and realizes the quick calculation and whole control of the car-distance by use of SPCE061A MCU.The system can provides the cars in high-speed driving with real-time information of surrounding cars,and provides drivers with the warning about safe distance.Tests prove that this system is efficient and reliable and is able to prevent serious traffic accidents from happening.
