On-demand maintenance monitoring method and system

The invention relates to an on-demand maintenance monitoring method and system. The method comprises the steps of a, carrying out the self-inspection of a fault elevator, and sending a maintenance request; b, carrying out statistics and analysis on elevator operation data before maintenance, and automatically generating an elevator recent fault report; c, monitoring the maintenance process; d, obtaining the elevator operation data after maintenance is completed and carrying out statistics and analysis; and e, evaluating the maintenance effect by calculating the maintenance quality index. The on-demand maintenance monitoring system realized by using the method comprises a maintenance sending unit, a pre-maintenance analysis unit, a maintenance process monitoring unit, a maintenance monitoring platform unit, a post-maintenance analysis unit and a maintenance effect evaluation unit. According to the on-demand maintenance monitoring method and the system, potential safety hazards of the elevator can be found in a
