4results about How to "Improve operation and maintenance work efficiency" patented technology

This invention provides a method, apparatus, and storage medium for the operation and maintenance of integrated utility tunnels. The method includes: collecting tunnel data; adding tags to the tunnel data to obtain a tagged data stream, the tags including spatial location tags, equipment affiliation tags, and time tags; constructing a digital twin model based on the tunnel data; obtaining an association mapping table for the digital twin model; establishing a virtual state of the twin model based on the association mapping table, the virtual state including a two-dimensional configuration view and a three-dimensional spatial view; performing time-series processing on the tagged data stream to obtain a time-series dataset; obtaining actual state data from the time-series dataset; comparing the actual state data with the virtual state of the twin model to obtain state difference data; and generating an operation and maintenance work order based on the state difference data. This method improves the efficiency of integrated utility tunnel operation and maintenance.

This disclosure relates to a container control method and electronic device. In response to a user's remote control request for a target container, the server displays a remote control interface, which includes a target control. In response to a user's trigger operation on the target control, the server generates a remote control instruction corresponding to the target control. The remote control instruction is sent to the target container, instructing it to perform a target operation, and includes mechanical control instructions and / or non-mechanical control instructions. Thus, users can remotely and actively control the target container through the server-side remote control interface, improving work efficiency.

This application relates to the field of high-voltage equipment safety technology, and in particular to an interlocking device for a high-voltage switchgear. The device includes a protective cover, a first rotating plate, a second rotating plate, a third rotating plate, and a linkage rod, all installed on the back of the high-voltage switchgear door. The first rotating plate is driven by a rotating column, and the second and third rotating plates rotate synchronously with the first rotating plate via the linkage rod. Each rotating plate is connected to a connecting rod and a locking pin. The rotation of the rotating plate drives the locking pins to extend or retract synchronously, achieving multi-point locking and unlocking of the door and door frame. The device also includes a telescopic assembly with a controller linked to the high-voltage switchgear's electrical circuit. This controller automatically controls the extension and retraction of the locking column based on the high-voltage switchgear's energized state, achieving forced locking during energization and automatic unlocking during power failure. This application simplifies the operation process, has a stable and durable structure, and effectively improves the operational safety and maintenance convenience of the high-voltage switchgear.
