摘要
针对多数公交车依靠单一GPS定位,存在的信号丢失、延时等情况,以及公交预报站不准确的问题,文中设计一种基于RFID和GPS数据融合的公交车辆精准报站系统。该系统主要采用有源RFID技术和GPS卫星定位技术,以GD32F103微处理器为主控制器,以LTE Cat1为主要通信传输方式,设计RFID读卡基站和车载终端设备。通过在公交车上安装具有RFID无线通信和GPS定位功能的车载终端设备,在公交站台上安装RFID读卡基站的方式,将车辆定位数据采集上报至云服务器。云服务器软件采用B/S结构,通过数据融合算法对RFID和GPS定位数据进行互补矫正,计算RSSI距离和GPS数据,综合得到更精确的定位数据,并推送至智能公交电子站牌进行公交预报站。测试结果表明,所设计系统可以有效提高车辆进站报站的准确性和及时性,从而弥补单一GPS定位的不足,实现智能公交电子站牌的精准报站,提高乘客换乘衔接效率,提升公交出行的服务质量。
In allusion to the signal loss,delay,inaccurate bus station forecast and other problems that most buses rely on single GPS positioning,a precise bus station report system based on RFID and GPS data fusion is proposed.In the system,the active RFID technology and GPS satellite positioning technology are adopted mainly,the GD32F103 microprocessor is taken as the main controller,LTE Cat1 is used as the main communication transmission mode,and the RFID card readingbase station and vehicle terminal equipment are designed.The bus positioning data is collected and reported to the cloud server by installing the on⁃board terminal equipment with RFID wireless communication and GPS positioning functions on bus,and installing the RFID card reading base station on the bus platform.The cloud server software with B/S structure can complement and correctthe RFID and GPS positioning data by means of data fusion algorithm,calculate the RSSI distance and GPS data to comprehensively obtain more accurate positioning data,and push it to the intelligent electronic bus station board for bus station forecast.The testing results show that the designed system can effectively improve the accuracy and timeliness of the bus arrival station report,so as to make up for the shortage of single GPS positioning,realize the precise station report of intelligent electronic bus station boards,improve the connection efficiency of passenger transference,and improve the service quality of bus.
