Core functions of the platform: First, one-code full traceability, each elevator generates a unique exclusive QR code. Owners can view elevator files, maintenance records, inspection reports, and complaint records by scanning the code, realizing "one-code universal query, one-code complaint"; Second, AI intelligent early warning, real-time collection of operation data through elevator IoT sensors, AI algorithm automatically identifies safety hazards such as door machine failure, steel wire rope wear, abnormal vibration, and overdue maintenance, and pushes them to maintenance units, property management and supervision departments in real time, realizing "early warning and early disposal"; Third, full supervision of maintenance, maintenance personnel must scan the code to sign in, upload maintenance photos and videos in real time. The platform automatically identifies false maintenance, missing maintenance, and overdue maintenance, which is included in the credit rating of maintenance units; Fourth, rapid emergency response, elevator entrapment automatically alarms, automatically locates, and automatically dispatches orders. The average rescue arrival time is shortened from 35 minutes to 22 minutes, and the trapped rescue disposal rate is 100%; Fifth, credit hierarchical supervision, the platform conducts credit ratings for maintenance units and user units, divided into four grades A, B, C, D. Grade D units are listed as key supervision objects, increasing the frequency of inspections and restricting participation in government procurement projects.
