两种基于北斗BDM100模块的家庭监护终端设计

Two Designs of Family Care Terminal Based on Beidou BDM100 Module

针对家庭监护中老人实时定位问题,结合北斗全球卫星定位系统和北斗模块BDM100,分别采用3G和2G模块设计了两种解决方案。3G方案中,采用AT91SAM9260芯片作为主控芯片,自定义通信协议,并封装了若干基于Linux操作系统的通信函数,具有良好的扩展性和稳定性。2G模块则采用LPC1766芯片,设计了具有良好健壮性的软件,成本低,对于单一需求的用户具有很好的适应性。

Combining Beidou global satellite positioning system and BDM100 module,two ways using separately 3G and 2G module are designed to solve the real-time positioning problem for old people in the family care field.In the solution with 3G,AT91SAM9260 is used as the main control chip,the communication protocol is user-defined,and several communication functions based on Linux are encapsula-ted.The design has good expansibility and stablity.In the solution with 2G,LPC1766 is used and the software with good robustness is designed,so that the design has low cost and good suitability for those users with single demand.
