摘　　要：针对图书馆中存在的学生代签以及离馆后久不退座的现象,设计并开发了一款基于GPS定位的图书馆座位管理系统。该系统实现了用户预约选座、签到、暂离、退座等功能,引入了上周情况反馈模块、排行榜模块,方便学生合理安排预约时间,实现了数据可视化。系统通过获取用户的GPS定位信息,结合点和面的拓扑关系算法——射线法,判断学生是否在图书馆内签到或者长时间离开图书馆,提高图书馆座位使用率。A library seat management system based on GPS positioning is designed and developed,in response to the phenomenon that students allograph or reservation and not returning after leaving the library for a long time.The system has realized the func⁃tions of user reservation and seat selection,check-in,temporary departure and seat withdrawal,and introduced the feedback mod⁃ule of last week's situation and the leaderboard module to facilitate students to reasonably arrange the appointment time and realize data visualization.The system obtains the user's GPS location information,and judges whether the students have checked in in the library or left the library for a long time by combining the algorithm of the topological relationship between the point and the sur⁃face--ray casting algorithm,so as to improve the efficiency of the library seat use.
