THE CONCEPT DESIGN OF OBSERVATION CONTROL SYSTEM FOR LIJIANG 2.4-METER TELESCOPE

The Lijiang 2.4-m telescope was built and opened to astronomers since 2008, now there are several instruments installed at the telescope. The control system of the 2.4-m telescope was designed to be operated in robotic mode as the Liverpool telescope, but due to many reasons it didn’t achieve robotic mode until now. After we upgraded the fold mirror by adding a rapid instrument exchanging system at the Cassegrain focus in 2012, now we can have up to 9 instruments on the telescope at the same time, but the control system for the instrument is still specific for each instrument. During the observation, change to different control software and operating system for different instrument are needed, which affects the observation significantly. Following the observation control system for few years, we are trying to develop a suitable observation control system for the Lijiang 2.4-m telescope. In this paper, we will introduce the Lijiang observatory, the 2.4-m telescope and its instruments at first, and then discuss the concept design of observation control system for this telescope which will based on the main purpose of improving the observation efficiency.
