Paper Abstract

The Iranian National Observatory telescope (INO340) [1] is a 3.4m Alt-Az reflecting optical telescope under design and development. It is f/11 Ritchey-Chretien with a 0.33° field-of-view. INO340 will be installed at Gargash summit near Kashan, Iran [2] and the first light is planned for 2016. The INO340 control system utilizes a uniform and well-defined architecture that achieves better system robustness, efficiency/performance, reliability and security. Besides improving system parameters, this architecture focuses on some important features for observation activities such as usability, remote observation, short service time, upgradability and extensibility. For this purpose distributed control through 4 different systems has been designed: Telescope Control System is responsible for the control of the telescope structure with its mirrors and dome. Observation System provides user interfaces for loading observing configurations, observation scheduling, resource allocation and etc. It also includes Instrument Control System which is responsible for control of instruments and science data management. Interlock/Safety System comprises all interlocks/safety related components required to guarantee person and equipment safety at the observatory. Another system plays the monitoring role for the whole observatory: Observatory Monitoring System. In brief, the OMS includes logging and archiving system for all engineering, operation and performance data. In this paper, we present the fundamental of the INO340 control system including high-level architecture, operational modes, main sub-system design and interfaces, communication technologies, middle ware and front-end.
