目标跟踪LabVIEW监控软件的设计与实现

Design and Implementation of LabVIEW Monitoring Software for Target Tracking

针对无线传感器网络目标跟踪的特点及技术要求,为了解决传统开发方式中软件可拓展性差、调试困难以及可操作性不强的问题,以LabVIEW为开发工具,采用模块化的设计思想开发了一个目标跟踪LabVIEW监控软件,讨论了该软件的设计方案、结构、各功能模块的设计与实现、程序设计中的难点及解决方法。在软件设计中使用消息队列法实现了并行线程间的数据同步,利用插值和滑动窗口法改善了移动轨迹的动态显示,采用距离限制滤波法提高了坐标的稳定性。所设计的监控软件实现了数据通信、处理、存储、节点状态显示、目标移动轨迹绘制等功能,完成了目标跟踪系统的上层监控任务。实验结果表明,该软件运行可靠,操作简便,易于扩展,跟踪效果良好,满足了目标跟踪监控的设计要求。

A LabVIEW monitoring software is developed, according to the characteristics and technical requirements of the target tracking. The traditional problems such as weak expansibility, bad debuggability and weak operability are solved, using LabVIEW development tool and the modular design concept. The architecture, implementations of each module, difficultis in the design and solving methods are discussed. Program realizes the data synchronization between parallel threads with the message queue method. The difficulties of dynamic and stable display of tracking are sovled, using the interpolation sliding window and limited distance filter method. The mian functions, such as data communication, processing, storage, display and moving target tracking are achieved. The results show that the software can accurately track a moving target and it has characteristics of high reliability, simplicity and expansibility. The design requirements are met.
