摘　　要：针对利用车辆集成专业设备进行实地督察存在的设备众多、数据获取离散、网络传输慢、成本高昂等问题,引入面向资源服务的思想(REST),综合利用地理信息、4G网络等技术,提出以移动智能终端作为土地督察的技术手段,研究基于CORS的差分定位、分布式缓存、信息安全传输策略等关键技术,设计基于移动端的土地督察解决方案,研发了基于BS/CS混合架构的、适用于移动端的土地督察信息系统。实际应用表明,该系统具有成本低、操作便捷、易于规模化推广等优点,对于违法用地不仅可以定性判断,还可定量勘察,有效提升了了土地督察的精准性。In view of the problems in the land supervision by vehicle integrated professional equipment,this paper applies resource oriented service thought(REST),utilizes geographic information and 4G network,proposes a mobile intelligent terminal as a technical means of land inspection,studies the key technologies of the differential positioning based on CORS,distributed caching and information security strategy,develops a mobile land inspector system based on BS/CS hybrid architecture.Compared with the existing vehicle supervision system,it has the advantages of low cost,convenient operation and easy to scale popularization.The practical application shows that the system can not only qualitatively judge the illegal land use,but also qualitatively survey,which effectively improves the precision of the land inspection.
