Design of a web-based remote control and automation system for sky-brightness measurements

The near-infrared spectrum encompasses three primary atmospheric transmission windows corresponding to the wavelengths J, H, and Ks. This paper introduces a practical automated remote-control system based on Web technology, which utilizes NIR sky brightness measurements for calibrating astronomical observational data. The system enables remote control, automated observation and data visualization. EPICS serves as the connection layer between the microcontroller and the server, implementing the underlying event loop. The web server leverages the Tornado framework to efficiently manage automated observational tasks and performs a real-time correction of the Ks device's detector response using a blackbody radiative source. The system provides a client interface constructed with the Vue framework and utilizing the Element UI component library, allowing users to remotely control instruments, monitor and configure observation tasks, as well as visualize data using the Plotly charting tool via a web browser.
