Abstract:With the increasing rate of urban cabling, the existing data management of underground cables lacks effective technical means. There is no effective solution for mobile inspection and real-time monitoring of underground cables. The lean management of underground cables is always a weak link in the production management of electric power industry because of the lagging policy and the limitation of technical conditions. In order to solve the problems of data acquisition, data management, mobile inspection and on-line monitoring of underground cables, the research and application scheme of key technologies of lean management of underground cables is put forward. Based on the concept of large data management, the holographic data model of underground cables is established. Type I; Using RFID power label to solve the problem of mobile inspection of cables for first-line crew members; Unifying the specifications of underground cable online monitoring equipment and data transmission interface, realizing real-time online monitoring of underground cables, providing underground cable operation and maintenance management departments with "standard, usable, visual and checkable" large data resources, and establishing "automation, intellectualization, refinement and establishment" Integration of underground cable lean management system to ensure the safe and stable operation of the power grid.
