Remote health monitoring system for the Chiang Mai 13-m VGOS radio telescope

The VGOS 13m radio telescope located in Chiang Mai, Thailand is the first VGOS standard station built overseas by China. This station expands Chinese very long baseline interferometry (VLBI) network (CVN) and furthers multiple scientific goals, such as continuous monitoring of Earth orientation parameters and research into the terrestrial and celestial reference frames. The station is equipped with a wideband 2-14GHz receiver and an X/Ka dual-frequency receiver, a fast-slewing antenna, a DBBC3 high-speed data acquisition terminal and a high-speed recording terminal. This is aimed at improving observation efficiency and research quality. We developed the Remote Health Monitoring System (RHMS) specifically for the VGOS 13m radio telescope located in Thailand. This system integrates Tango Controls’ distributed middleware technology, allowing it to furnish the observation team with comprehensive historical and real-time status updates for the Chiang Mai VGOS station. Additionally, it promptly issues alerts for abnormalities, thereby improving the station’s unmanned monitoring, maintenance and operations capabilities, and operational performance. It also provides a feasible solution for remote monitoring of future overseas VGOS stations.
