摘要 为了更加直观方便的监测定位目标的位置及运行情况,设计了一款定位跟踪系统,采用单片机ATmega128A为处理器和惯性器件MPU6050为核心的集成一体化的硬件接收机终端为基础,监测软件是以LabWindows/CVI为平台,做了将定位终端携带在实验目标上,监测目标运行轨迹的实验。通过采集软件得到了目标经纬度坐标,并实时显示转换后的平面坐标,最后利用卡尔曼滤波算法来优化外界对目标定位跟踪的干扰,实践测试结果表明该系统运行稳定、定位效率高、方便携带、外界干扰小、发展前景广阔。 In order to be more intuitive and convenient to monitor the location and operation of positioning targets,in this paper,a locating and tracking system is designed,which is based on the integrated hardware receiver terminal,which is the core of atmega128a processor and inertial device MPU6050,and the monitoring software is based on LabWINDOWS/CVI,and the experiment is done to carry the locating terminal on the experimental target and monitor the track of the target.The target latitude and longitude coordinates are obtained by the acquisition software,and the planar coordinates are displayed in real time,and finally the Kalman filter algorithm is used to optimize the disturbance of the target locating and tracking,and the practical test results show that the system has stable operation,high positioning efficiency,convenient carrying,small outside interference and broad development foreground.
