RACS2: a framework of a remote autonomous control system for telescope observation and its application

With the increasing demand for astronomical observations, telescope systems are becoming increasingly complex. Thus, observatory control software needs to be more intelligent. It has each instrument inside observatory, finish observational tasks autonomously, and report information users if needed. We developed a distributed autonomous framework named Remote Autonomous Control System 2nd (RACS2) meet these requirements. Rich features integrated into RACS2 framework. The is modular framework, in which device system services implemented as different components. Furthermore, assimilates new techniques, such lightweight message serialization mechanism. also good compatibility with other frameworks or ecosystems Python EPICS (Experimental Physics Industrial System). can communicate EPICS-based Python-based software. help of features, key components like executor, scheduler developed. executor component support sophisticated tasks. observation achieved by component. A set web-based graphical user interface (GUI) designed manage remotely. Based on we have Dome Twins (DATs) telescope’s space object system. been operated than 1 year. used our projects camera Wide Field Survey Telescope (WFST) its system, design useful reference development frameworks.
