基于北斗GPS模块UM220和四频GPRS模块SIM800H的人员定位应用研究

Application research of UM220 Beidou/GPS module and SIM800H GPRS module

针对使用北斗进行人员定位管理的目的,采用北斗GPS双模定位模块UM220获得北斗和GPS定位信息,通过两种定位信息优化定位精度,通过四频GPRS模块SIM800H的基站定位功能辅助定位,并将获得的定位信息进行传送和通信,从而实现人员的定位管理。采用模块化设计体积小巧、功耗低,采用北斗GPS两种定位优化定位精度可达2.0 m。

For the purpose of using the Beidou positioning of personnel management, the use of dual-mode GPS positioning module UM220 Compass Compass and GPS positioning information obtained, optimizing location accuracy by two positioning information, by quad-band GPRS module SIM800 H base station positioning assisted positioning, and the obtained Location information for transmission and communication, in order to achieve localization managers. The modular design of compact, low power consumption, the use of two Beidou GPS positioning optimization positioning accuracy up to 2.0 meters.
