基于LabVIEW丰富的网络互联工具和强大的数据处理能力，建立了一种针对物流运输行业的多终端定位追踪系统。本文介绍了硬件系统的GPS配置方法，以及利用GPRS实现了基站定位功能，详细论述了LabVIEW如何调用百度地图API，如何实现对GPS定位信息的解析、坐标系转换、网页信息获取与解析、多终端定位、速度与航向角惯性推算等功能。通过多次系统功能测试，获取了大量数据，经过数据分析和系统调试，完善并提高了系统的功能和可靠性。实验结果表明，该设计方案具有精度较高、成本低廉、结构简单等优点，具有一定的实际使用价值。
Based on LabVIEW’s rich internet tools and powerful data processing capability, we establish a multi-terminal location tracking system for logistics industry.This paper introduces the hardware system GPS configuration method, and the use of GPRS to achieve the function of the base station positioning.It discusses how LabVIEW calls Baidu map API, and the way to achieve the analysis of GPS positioning information, coordinating system transformation, web page information acquisition and analysis, multi-terminal location, speed and heading angle inertia calculation and other functions. Through a number of system function tests, we get a large number of data. By data analysis and system debugging, we improvethe function and reliability of thesystem.The experimental results show that the design scheme has the advantages of high precision, low cost and simple structure, it has a certain practical reference value.
