动力翼伞地面站的设计和实现

Design and implementation of powered parafoil ground station

为实现对动力翼伞飞行的实时监测和地面操控,结合SQL Server数据库技术、C#可视化编程语言和Visual Studio 2015开发编辑工具,设计了一款面向动力翼伞的地面站系统。该系统包括数据处理、飞行监测、数据存储、飞行信息回放、轨迹规划等功能模块。无线数据传输设备接收动力翼伞的飞行信息,经卡尔曼滤波算法滤波处理,实现仪表、双地图等多种表现形式;融合SQL Server数据库技术,实现历史数据灵活截取、调用;利用历史数据和扩充数据,运用风场辨识算法,对低空飞行的风场信息进行估测,捕获环境信息。通过飞行实验,能够绘制清晰的轨迹信息,并将风速和风向的辨识平均误差分别控制在0. 35 m/s和4. 04°的小范围内。

In order to achieve real-time monitoring and ground manipulation for powered parafoil flight, a ground station system for powered parafoil was designed based on SQL Server database technology, C # visual programming language and Visual Studio 2015 development tool. The system included data processing, flight monitoring, data storage, flight information playback, trajectory planning and other functional modules. Wireless data transmission device received powered parafoil flight information, and through Kalman filtering, many forms of expression such as instrument dial, double map and so on were realized. SQL Server database technology was used to realize flexible interception and call of history data; historical and extended data and the wind field identification algorithm were used to estimate wind field in low altitude flight and capture environmental information. Through flight experiments, clear trajectory information could be drawn, and the average error of wind speed and wind direction were controlled in a small range of 0.35 m/s and 4.04 degrees respectively.
