Description

Technical Field

[0001] This invention relates to the field of charging pile monitoring technology, specifically to a charging pile monitoring system and method. Background Technology

[0002] With the penetration rate of new energy electric vehicles increasing year by year, reaching 50% by 2024, electric vehicles, while bringing convenience, have faced challenges in charging and range management, directly impacting their convenient and safe use. To meet the charging needs of electric vehicles, charging stations are needed in various areas, typically distributed across different locations. Consequently, monitoring and management of these charging stations are required.

[0003] A prior art publication (CN 115775416 A) discloses a charging pile monitoring and management system and method. The method includes the following steps: a cloud server receives input charging pile inspection information and generates inspection tasks based on this information; it broadcasts inspection instructions to inspection terminals and receives response information from these terminals; it records the terminal numbers and quantities based on the response information, divides the inspection tasks into regions, and subdivides them into sub-inspection tasks equal to the number of inspection terminals, assigning each sub-inspection task to a corresponding inspection terminal; after receiving a sub-inspection task, the inspection terminal networks with the charging piles within the region; it generates an inspection route based on its current location and the sub-inspection tasks, and inspects the charging piles within the network; it processes the detection data, issues on-site alarms for any abnormalities, and uploads the inspection results to the cloud server; this method eliminates missed inspections during the inspection process.

[0004] Although the aforementioned technical solutions can detect abnormal information and issue on-site alarms, they can only monitor abnormal charging piles during the charging process or charging piles that are connected to the grid without abnormalities. They cannot detect charging piles with actual hardware damage that are not connected to electric vehicles. Furthermore, when a charging pile is damaged, most car owners will only think of replacing the charging pile after plugging and unplugging it a few times, and will not take the initiative to contact the repair department for repairs. This makes it difficult to detect charging piles with damaged charging functions in a short period of time. Summary of the Invention
