摘要: 为了提高公交系统的运营效率, 设计了基于短信服务的智能导航车载系统, 分析了导航系统和车载系统的运行原理和功能。采用公交车到站发短信的方式, 能够在每个停车站点的电子站牌上显示距离本站最近的车辆到达所需的时间, 同时控制中心可对车辆进行实时调度, 动态查询车辆的位置区间。实验测试结果表明: 该系统设备性能稳定, 能够实现运行车辆的有效管理, 且投资小, 收益快, 同时具有一定的扩展性, 易于与相关的智能系统衔接。Abstract: In order to improve the operation efficiency of public traffic system, the data flow of public traffic system was analyzed, a vehicle device of intelligent guiding system was designed, and the structure of the system based on SMS(short message service) was studied. The system could transmit the information of public traffic among buses, bus stations and management centers. Applied results show that the system equipment performance is steady, the system can realize vehicle management effectively, and connect with other intelligent systems easily.
