Aiming to the features and demands of transmission line information management and merging the remote sensing images, digital elevation model and GIS layers, this paper creates a three-dimensional scene of transmission line, which takes TerraExplorer Pro as basic platform and combines the attribute information of transmission line, and develops an interactive and visualized management system which is oriented to power system. The system realizes the 3D display, query and analysis of transmission line and provides the integrated supports to the design, construction, operation and maintenance at a certain extent

According to characteristic process and control requirements of tire liner, the old process was rebuilded, combining with more precise and high efficiency control system, a new process method was designed. By practicality production, the system is stabilization, improving productivity and quality.
