Reliability Optimization Strategy for Antarctic Telescope Control System

Antarctic telescopes, especially those located at Dome A, face significant reliability challenges due to the extremely harsh working environment, among which the reliability of the control system is critical to ensuring its stable operation. This paper describes the factors affecting the reliability of Antarctic telescopes from various aspects, as well as the challenges of reliability improvement. Combined with the development of Antarctic telescope and the experience of Antarctic scientific expeditions, the author introduces in detail the optimization strategy of reliability enhancement including hardware layer, software layer, modularization and maintainability design, and reliability management. Furthermore, the current status of the Antarctic Survey Telescope (AST3) is briefly introduced, along with future development plans. To a certain extent, this paper can provide ideas for the reliability design of Antarctic telescopes, and provide technology and experience accumulation for the development of China's next-generation Antarctic telescope projects.
