平流层气球吊篮姿态远程视景监控系统设计

The Design of Stratospheric Balloon-borne Gondola Motion Remote Virtual-scenes Monitor and Control System

气球飞行于大气同温层带时,球载吊篮由于受到强大气扰动力的影响,相对于基准姿态存在随机转动和摆动的姿态偏差,该偏差会导致吊篮靶斑机构瞄准线方向偏离其对地面光源点的指向,从而影响科研数据的搜集。该文结合平流层气球吊篮及姿态控制系统的研制,介绍了吊篮姿态的解算过程以及利用LabW indows/CVI平台及OpenGL图形库开发仿真视景监控软件对吊篮实施遥控遥测的方法,软件开发过程利用组件技术建立视景对象模型,提高了软件的灵活性、可移植性和可扩充性。软件对气球吊篮的飞行全过程进行模拟仿真,直观、实时地反映了气球吊篮在高空的飞行姿态,并且有效地对吊篮姿态完成了干预控制。

When balloon -borne gondola flies in stratosphere, gondola will deflect relative to its normal motion status due to intense atmosphere disturbance, which leads normal vector of drone that hung under gondola to deviate the direction of ground＇s lamp - house and influence the measurement of scientific data. Through the development of stratospheric balloon - borne gondola and motion control system , this paPer introduces the methods for calculating gondola motion＇s deflection error and the remote control and monitor of gondola. In the program, component technique is used to create scenes＇object model which improves software＇s performance of flexibility , portability and extensibility. Virtual - scenes simulate the whole flying course of balloon - borne, realistically and simultaneously demonstrate the balloon- borne＇s motion at high altitude.
