Research on Intelligent Auxiliary Technology for Verifying Elevator Governor Based on Mixed Reality

To address issues such as the complexity and difficulty of elevator wire rope detachment and governor verification operations, this study combines mixed reality (MR) with 3D digitalized governor verification processes. Key technologies such as 3D modeling of the governor verification workflow, three-dimensional registration, tracking, and fusion display were investigated. An MR intelligent assistance prototype system for elevator governor verification was developed to enable MR operation guidance. The application results demonstrate that MR technology can provide real-time, intuitive operational support and training environments for inspectors, enabling full-process marking guidance for the inspection and maintenance of critical components. This improves operational accuracy, enhances employee training efficiency, reduces operational errors, minimizes safety risks, and elevates the intelligent inspection standards of the elevator industry.
