摘要： Elevator systems and methods are provided. The systems include an elevator car including an elevator car door interlock device operable to open and close elevator car doors and a plurality of landing doors located at landings, each landing door including a landing door interlock device operable to open and close a respective landing door. Each landing door interlock device is engageable by the elevator car door interlock device to operate the elevator doors. An elevator component inspection system having a detector to monitor the interlock devices obtains inspection data associated with the interlock devices. A control unit is configured to analyze the inspection data. The component inspection system captures images of the interlock devices using the detector, performs a database inquiry comparing the captured image against a database of interlock device states, and determines a state of the interlock devices.
