Description
To achieve highly reliable and efficient automated observation and operation of Large Array of Imaging Atmospheric Cherenkov Telescope, this paper presents the design of the core architecture and key modules for an integrated control system.
Addressing the core challenges of LACT, including distributed multi-device deployment, integration of heterogeneous equipment, and coordination of complex observation workflows, a distributed and modular system design based on the TANGO control framework is proposed.
The design functionally decouples and integrates key subsystems—such as telescope drive control, front-end electronics monitoring, mirror adjustment, environmental monitoring, and real-time pointing calibration—establishing a unified control model and data interface.
The system design focuses on an automated workflow engine capable of parsing observation plans, monitoring equipment status, and scheduling task sequences.
It also incorporates an integrated operational module combining data archiving, state alarming, and preliminary fault diagnosis to support stable, unattended or minimally attended operation.
For user interaction, the design proposes a front-end/back-end separated architecture based on web technologies, laying the foundation for a future unified portal encompassing observation control, status visualization, and data management.
The proposed system design aims to meet the fundamental requirements of scalability, reliability, and automation for LACT's future large-scale construction and scientific operation, while also providing a referential paradigm for the integrated control of similar large-scale astronomical facilities.
