The artificial intelligence operation unit resets the accumulated value at regular intervals to analyze the accumulated value in a specific period, and the grounding system abnormality prediction model is a structure for analyzing data on the accumulated value using a circulation network. Created,
The manager notification device displays data by date and time, provides periodic and conditional data through a search option of a website or application, and collects data of an area where the grounding system is located through location-based information. An artificial intelligence-based ground monitoring system that provides information on the current status of the ground system in the area. delete delete
