基于单片机的采集与处理北斗定位信息系统

A collecting and disposing system for BDS based on single chip microcomputer

针对当代社会空巢老人的增多,突发意外时不能及时呼救的问题,设计了一款基于北斗定位系统的集应急报警与信息交互为一体的多功能报警器。该报警器采用双串口单片机为主处理器,以北斗定位模块为核心,结合GSM无线通信模块、液晶显示模块及蜂鸣器,实现快速报警并发送所在位置信息的功能。简述了硬件与软件的实施方案及定位信息采集原理,通过多方面对比北斗与GPS定位模块的速度与检测卫星数来比较二者性能,实验结果表明,该系统具有定位快速、可靠性与稳定性较高等特点。

In view of the increases of contemporary social empty-nesters and the problems of can not call for help in time when sudden accidents occur,this paper designs a model of the multi-function alarm for the integration of emergency alarm and information interaction based on BDS（Beidou Navigation Satellite System）.Adopting the dual-serial-port single-chip as the main processor,taking BDS positioning module as the core,incorporating the GSM（Global System for Mobile Communication）wireless communication module,liquid crystal display module and the buzzer,this system achieves the function of alarming rapidly and sending the information of location.This paper expounds the implementing scheme of hardware and software,as well as the principle of positioning and collecting information.Through various contrasts DBS with the speed of the GPS module and the number of its detecting satellites to compare both performances,experimental results demonstrate this system enjoys the characteristics of rapid positioning,high reliability and stability,etc.
