摘要
针对国家对智慧景区的建设需求,提出了一种基于北斗导航的智慧景区位置服务系统体系架构,并深入分析了广域连续覆盖定位技术、广域连续覆盖通信技术等关键技术内涵。以九寨沟风景名胜区为试点,开展了九寨沟智慧景区位置服务系统的研制与布署,该系统将北斗导航技术、伪卫星增强技术、差分高精度增强技术和智能位置服务技术相结合,具备游客位置服务、景区精细化管理与应急事件处理三大应用服务。通过实际测试,满足50 000用户的同时接入,响应时间小于2 s,已全面支持九寨沟景区的日常化管理。
In view of national demand for the construction of smart scenic spot,this paper proposes a smart scenic spot location-based service（ LBS） system architecture based on beidou navigation,and analyzes in depth the connotation of such key technologies as wide-area continuous positioning technology,wide-area continuous cover communication technology,etc.Taking Jiuzhaigou scenic spot as a pilot project,a smart scenic spot LBS system is developed and deployed.The system combines beidou navigation technology,pseudolite augmented technology,GNSS differential technology and intelligent LBS technology.It can provide such three application services as tourist location service,fine management and unexpected-event handling.The results of practical test show that this system can meet the synchronous access of 50,000 users and the response time is less than 2 s.It can support the routine management of Jiuzhaigou scenic spot at present.
