校车实时位置查询APP设计与实现

Design and implementation of school bus real⁃time location query APP

为了促进教育均衡发展、优化教学资源配置、降低办学成本,学校进行了大规模的布局调整和撤并[1]。校际班车成了各校师生联通的必备工具,校车实时位置和行驶轨迹是师生和家长共同关注的问题。校车实时位置查询APP研究的内容是校车在行驶过程中,利用移动端APP将司机手机的GPS定位服务信号转化为校车的实时位置信息,并准确及时上传至服务端。乘车师生在APP端自动或手动动态从服务端获取所选校车的最新位置信息,并以地图和文字形式呈现。提高了校车服务的可见度,使教师和学生的出行时间管理更科学、更精确。本APP利用先进的互联网地图服务接口,将位置信息转化为可视化的校车实时位置,不需要购买装置,节约硬件投入成本。
