摘要
针对特殊群体的实时位置跟踪需求,研究了GPS位置数据获取算法和数据采集时间间隔更新算法,设计实现了基于ARM和Google Maps的手机位置跟踪系统。用户只需随身携带GPS手机,监护人即可通过嵌入式移动终端在地图上实时查看其位置信息,并在用户接近和进入危险区域时报警,可应用于老人、小孩、残疾人等特殊群体的保护。基于ARM的嵌入式位置信息数据库保存了用户出行数据,为智能手机定位的大数据研究提供支持。通过对GPS数据重复性、位置信息数据库以及ARM位置跟踪系统的性能测试,验证了算法的有效性及设计思路的可行性。
In view of the demand of real-time location data acquisition and location tracking for special groups,GPS location data acquisition algorithm and the update algorithm for data acquisition interval are studied in this paper. The mobile location tracking system based on ARM and Google Maps are designed and implemented. The users take GPS smart phones with them when they go out. The guardian can check their location in real- time on the map through portable embedded terminals. It send out alarm information when users are close to or enter the danger zone. It can be widely used in the elderly,children,the disabled and other special groups of protection. The embedded location information database is created based on ARM platform,which is used to store all the time and location data when users are not at home. It can provide data support for big data research based on the smart phone positioning data. Experiments tests the reproducibility of the GPS data,the performance of location information database and ARM position tracking system,and verified the effectiveness of the algorithm and the feasibility of the design.
