The All-sky Information Acquisition System of Antarctic Zhongshan Station

The Antarctic Plateau has unique astronomical observation conditions. In order to conduct actual research on the night astronomical observation conditions of the Antarctic Zhongshan Station, the Yunnan Astronomical Observatory of the Chinese Academy of Sciences has specially developed a set of fully-automatic full-automatic fully adapted to Antarctic climate performance such as low temperature resistance, automatic snow and defrost Day information Acquisition system. The system can provide real-time all-sky cloudiness, skylight background and all-day images, and can push the information to the webpage for real-time display. This paper introduces the development of this system and the experiment of low temperature resistance to adapt to Antarctic climate. After statistical analysis of Zhongshan Station's all-day information data from 2016 to 2017, the result shows that the observable hours of Zhongshan Station in 2016 and 2017 are 772.21 h and 437.38 h, the number of observable nights is 93 d and 51 d, and the maximum true value of sky darkness is 22.05 Mag/aresec², the average temperature from 2016 to 2017 was -10.6 ℃, the highest temperature was 19.1 ℃, and the lowest temperature was -44 ℃, and the average relative humidity in 2016 was 55.2%.
