【摘要】：在飞行体落点定位中，采用人工排查的方法费时费力，且在飞行试验阶段，由于种种原因经常会引起飞行异常、偏离预定飞行轨迹或造成中途掉落，造成落点查找的难度加大。因此，迫切需要一种有效对飞行体落点定位的方法，以及设计相应的高速飞行体落点定位系统。本文重点研究了地理信息技术（GIS）、全球卫星定位技术（GPS）、电子技术和现代通信技术。通过对各种定位方法的分析比较，最终采用GPS定位方法。根据GPS原理和定位系统设计指标，设计了包括GPS接收机模块、无线传输模块和上位机显示模块的高速飞行体落点定位系统。系统分为载体部分和上位机部分。载体部分以u～blox6GPS接收模块接收目标点的地理位置信息，通过JZ873无线数传模块将信息发送出去。上位机部分的JZ878数传模块在接收到目标点的位置信息以后，经过RS232接口将信息传输给PC机的地图显示系统进行显示。在高速飞行体落点定位系统整体设计框架下，本课题对上位机显示系统也作了详细设计。利用GIS相关技术制作区域电子地图，，在Microsoft Visual Basic6.0开发环境下，完成电子地图的开发，实现了电子地图的基本功能操作、数据存储与查看、数据的地图化、PC机与载体端的数据通信等功能。上位机显示系统是一个集数据获取、数据存储、结果显示、输出等多功能为一体的系统，能够对接收到的信号经过分析处理，并在电子地图上显示出目标点所处的位置。最后进行了整体系统调试，结果表明：定位显示系能统将多个飞行体目标的地理信息地图化后显示在地图上，整体系统运行稳定且达到精度要求。
[Abstract]:In the positioning of the flying body, it is time-consuming and laborious to use the method of manual search, and in the flight test stage, the flight anomaly is often caused by various reasons, deviating from the scheduled flight track or causing the falling down in the midway, which makes the difficulty of finding the landing point more difficult. Therefore, there is an urgent need for an effective method to locate the landing point of the flying body and the design of the corresponding high-speed flying body landing point location system. This paper focuses on geographic information technology (GIS), global positioning technology (GPS), electronic technology and modern communication technology. Through the analysis and comparison of various positioning methods, the final GPS positioning method is adopted. According to the principle of GPS and the design index of positioning system, a high-speed flying body landing location system including GPS receiver module, wireless transmission module and upper computer display module is designed. The system is divided into carrier part and upper computer part. The carrier part receives the geographical position information of the target point by u~blox6GPS receiving module, and sends the information through the JZ873 wireless data transmission module. After receiving the position information of the target point, the JZ878 data transmission module of the upper computer transfers the information to the map display system of the PC through the RS232 interface for display. Under the frame of the whole design of the high-speed flying body landing point positioning system, this subject also makes the detailed design to the upper computer display system. Using GIS technology to make regional electronic map, under the development environment of Microsoft Visual Basic6.0, the development of electronic map is completed, and the basic function operation, data storage and view of electronic map are realized. The function of data communication between PC and carrier. The upper computer display system is a multifunctional system which can acquire data, store data, display the result, output and so on. It can analyze and process the received signal and display the position of the target point on the electronic map. Finally, the whole system is debugged. The results show that the positioning display system can display the geographic information of multiple flying objects on the map, and the whole system can run stably and achieve the precision requirement.
