• Abstract:About ten years ago,we established the first coronagraph that has been continuously operating on the high plateau of western China. This coronagraph is an internal occulting,10 cm aperture instrument,installed at Lijiang Station through a collaboration with the Norikura Station of the National Astronomical Observatory of Japan. To ensure high efficiency in current and future coronal observations,developing integrated observation systems is essential for reliable,autonomous,and remote operation of coronagraphs. This paper introduces an advanced integrated observation and control system based on the Lijiang 10 cm coronagraph. The system focuses on solar inner corona observations and integrates precise pointing and tracking,multi-band filtering,dome protection,and data storage subsystems. Extended operational tests demonstrate the stability,automation capability,and efficiency improvements of the system,which will support future coronagraphs for coronal magnetism diagnostics.
