定位数据访问框架的设计与实现

Design and implement of location data access framework

目前定位应用访问定位数据的方法常和特定的技术绑定在一起,这种相关性限制了应用向新技术的移植,也将最终用户绑定在了特定的设备上。通过对现存的定位技术方案的研究,抽象出了通用的定位数据访问模型,根据模型给出了定位数据访问框架的体系结构和实现方法。框架对定位应用屏蔽各种定位数据访问的细节和定位数据接收终端硬件的差异,为定位应用提供个一个与平台、技术体制和设备独立的定位数据访问接口。

Location based application＇s location data access development method are band the specific technology together. Because the application has such a strong relationship with the specific technology, application＇s transplantation can hardly be implemented. Thus, the end-users must use the specific type equipment. Location based application development method are researched and a general location data access process are modeled. According to this model location data access framework architecture are made up and the implementation of the frame work are given. The details of the way access location data and the receiving terminal hardware differences are hided behind the framework thus end-users need less background knowledge. An interface that is operating system platform independence position system independence equipment independence is provided for location based application developer.
