| description | The invention discloses a data analysis-based autonomous operation and maintenance research and judgment method for an early fault of a charging pile. The method comprises the steps of collecting public data of holidays, weather and temperature of operation of a charging station and operation data and information of the charging pile; performing statistical calculation on the communication online rate Rcom, the one-time charging success rate Rchg, the accumulated charging duration Tchg and the accumulated charging electric quantity Echg of each charging pile by taking day/month/year as a statistical cycle to obtain a calculation result; and carrying out statistical calculation on the voltage demand difference Ud, the current demand difference Id, the time demand difference Td, the operation temperature difference Dd and the power demand satisfaction rate Rpow of each charging pile, and when deviation data of a calculation result exceeds the standard and reaches an early warning condition, informing operation |
