Upgrade of the online data quality monitoring system for future PandaX experiments

PandaX-4T is a xenon-based multi-purpose experiment, focusing on particle and astrophysics research. The data quality monitoring system plays a crucial role in the experiment. This system enables the prompt detection of potential issues during data collection. In order to meet the upgrade requirements of the experiment, we have implemented several updates to improve overall data throughput and provide users with more comprehensive information. As a result, the system is capable of monitoring half of the collected data in future operations of the PandaX-4T experiment. Furthermore, with updated hardware, the system is also well-equipped to meet the requirements of the future multi-ten-tonne level PandaX-xT experiment.
