摘要
该系统以GPS和GPRS二合一模块SIM908为设计载体,利用STM32F103单片机为控制核心。轨迹跟踪器对GPS接收器返回的数据进行解析并提取有效定位数据,利用GPRS(通用分组无线服务技术)将有效定位数据传输至远程控制中心,控制中心对轨迹跟踪器系统传输信息进行分析,完成对轨迹跟踪器的实时定位。该系统能耗低精度高可靠性好,对于实时监测孤寡老人的出行安全有重要意义。
The system uses GPS and GPRScombomodulesim908 as the design basis,STM32F103 microcontroller as the control core. Trajectory tracking of data returned by the GPS receiver and the microcontroller parse and extract the effective positioning data,the use of GPRS( general packet radio service) will be effective positioning data transmission to the remote control center,control center to transmit informationto analyze the trajectory tracking control system,complete trajectory tracking of real-time positioning of the device. The system has low energy consumption and high precision,and the specific means of the inspection of living alone elder's travel safety in real time.
