Abstract： The observation and study of all kinds of variable stars are important part of time domain astronomy. Xinglong Observatory, NAOC as the largest observatory in the Asia continent. It owns several meter-aperture astronomical telescopes, which are opened to scientists from all countries. There telescopes are observing a lot of variable stars, but a dedicated data reduction pipeline is lacking. This paper introduces an automatic pipeline, which can extract light-curve from raw observation data. This pipeline is highly modularized and customizable, and can be applied to data from different optical astronomical telescopes after minor customization. The structure, the feature, and the usage of this pipeline are discussed in this paper, together with a sample of eclipsing-binary UY UMa. In the end, the limit of this pipeline is listed with future improve planning.
