Embodiment 1

[0014] Embodiment 1, with reference to figure 1 , figure 2 : The main cable 2 of the suspension system of the balloon crane adopts multi-strand outer bushing nylon rope without internal stress. The main cable is equipped with a rare-earth DC motor as the anti-twist motor 1, and a gearbox is provided at the same time, so that the main cable becomes the instantaneous vertical axis of the platform. The lifting beam 3 is set above the hanging basket to bear the pulling force of the platform, so that the converging force is closed. A magnetic sensor 5 and a step-by-step subdivision angle measuring box 4 are installed on the crane to establish a dynamic angle with the magnetic force line, provide corresponding output signals, control the platform orientation, and participate in the three dynamic balance signals of reverse twist, step direction, and torque flywheel control. The observation instrument is fixed on the pitch axis 6, which realizes angle measurement, transmission, an...

Abstract

The invention relates to a method for controlling directional posture of the nacelle of the high altitude balloon used in astronomical observation. The working steps are as follows. The counter twist electrical motor is installed on the main cable of the nacell. There are the stepping subdivided angle measuring box, the magnetic sensor, the pitch axis, the large flywheel and the moment electrical motor. When directional posture of the nacelle is changed, the said angle measuring box or the magnetic sensor measures the change of the magnetic line, outputting the signal. Based on the said signal, the counter twist electrical motor rotates reversely to balance out the change in orientation. The moment electrical motor transfers the control moment to the azimuth axis to play directional action.

Description

technical field [0001] The invention relates to an astronomical detection instrument, in particular to a 32km balloon astronomical observation platform, which is a directional attitude control crane. Background technique [0002] After World War II, countries around the world used high-altitude balloons for scientific research quite actively. In the early 1980s, the Space Research Office of the Purple Mountain Observatory carried out this research work, and the space astronomical exostratospheric gamma and X-ray astronomical observations have a history of 20 years. Astronomical observation instruments have their unique characteristics, which require the observation system to have positioning, orientation, and precise tracking requirements. The traditional approach is to use geomagnetic positioning or sun angle machines to build a stable space platform, and put on small and medium-sized astronomical observation systems to realize tracking, photography and spectral energy spe...
