摘　　要：设计了以52单片机为控制器的简易行人导航系统,利用MPU6050运动处理传感器计算实时三轴加速度、速度,采用QMC5883L弱磁通传感器得到实时航向角。这些采集到的数据经过处理即可获取行人的位置数据、行走方向、行走速度,并通过LCD12864将数据显示出来,实现行人位置及运动状态的实时定位。通过对系统实物进行测试,得到了基本的行人导航所需简易信息参数,验证了本设计的正确性。A simple pedestrian navigation system was designed based on 52 single chip microcomputer.The real-time three-axis acceleration and velocity were calculated by using MPU6050 motion processing sensor,the real-time heading angle was obtained by using QMC5883L weak magnetic flux sensor.The collected data can be processed to obtain pedestrian position data,walking direction and walking speed.The data can be displayed by LCD12864 to realize real-time positioning of pedestrian position and movement state.By testing the real object of the system,the basic simple information parameters for pedestrian navigation were obtained,which verifies the correctness of the design.
