22 Nov 2015 | | Abstract: | For an unattended telescopes in Antarctic, the remote operation, autonomous
observation and control are essential. An EPICS (Experimental Physics and
Industrial Control System) and RTS2(Remote Telescope System, 2nd Version) based
autonomous observation and control system with remoted operation is introduced
in this paper. EPICS is a set of Open Source software tools, libraries and
applications developed collaboratively and used worldwide to create distributed
soft real-time control systems for scientific instruments while RTS2 is an open
source environment for control of a fully autonomous observatory. Using the
advantage of EPICS and RTS2 respectively, a combined integrated software
framework for autonomous observation and control is established that use RTS2
to fulfill the function of astronomical observation and use EPICS to fulfill
the device control of telescope. A command and status interface for EPICS and
RTS2 is designed to make the EPICS IOC (Input/Output Controller) components
integrate to RTS2 directly. For the specification and requirement of control
system of telescope in Antarctic, core components named Executor and Auto-focus
for autonomous observation is designed and implemented with remote operation
user interface based on Browser-Server mode. The whole system including the
telescope is tested in Lijiang Observatory in Yunnan Province for practical
observation to complete the autonomous observation and control, including
telescope control, camera control, dome control, weather information
acquisition with the local and remote operation. | | Source: | arXiv, 1511.6950 | | Services: | Forum | Review | PDF | Favorites | |
