Abstract: EPICS, a software tool extensively used in large-scale scientific experiments such as particle accelerators. Depending on the scale of the facility, the number of EPICS PV can range from tens of thousands to millions. The ability to swiftly retrieve information related to EPICS PV can notably enhance the operational efficiency and maintenance of particle accelerators. To address this requirement, we designed and developed the EPICS PV information platform. This platform provides a unified user interface that supports the querying of PV lists, real-time statuses, historical data, put logs, IOC statuses, and IOC network information. It integrates these data points to offer a comprehensive view. The user interface of the platform leverages Web technology, with the server-side developed in the Node.js environment. This is complemented by software modules from the EPICS community. In addition, programs for network information collection and other cyclical executions are developed using the Python language. At present, the EPICS PV information platform has been successfully implemented in the CSNS accelerator, where it has significantly contributed to its effective operation and maintenance.
