Abstract
The ultraviolet (UV) spectrometer installed on the balloon platform is a cost-effective instrument to observe the UV spectrum of near space, which can meet the needs of biological evolution and planetary material exchange research. A control system of an enhanced UV spectrometer is designed in this paper. Firstly, the framework of the control system is introduced, and the functions of each module are described. Then, the solar angle sensor and automatic air pressure balance device in the enhanced detector module are introduced, making the detector operate safely and reliably in solar radiation and low-pressure environments. Next, the temperature controller is introduced, which can automatically adjust the heating power through the PID algorithm in the embedded chip according to the data collected from the light body and the atmosphere. Finally, the automatic detection mode is described. Among them, the controller can automatically adjust the system gain and integration time according to the spatial ultraviolet radiation intensity information, thus maximizing the efficiency of data. The flight test results of Honghu HH-20-7, HH-20-9 and HH-19-7 show that the spectrometer works normally in the flight experiment. Compared with the ultraviolet radiation in the MODTRAN database, the ultraviolet spectrum data of adjacent space obtained by the spectrometer has the same consistency, but provides a lot of detailed information.
