Construction and application of distribution cable mobile GIS system supported by GNSS

In order to meet the requirements of information and intelligent management of distribution cables, this paper designs and develops a mobile GIS management system for distribution cables based on satellite navigation positioning, mobile internet, geographic information system and other technologies, which solves the technical problems such as fragmentation of cable channel elements, integrated storage of cable well profile data and spatial data, high-precision positioning of mobile devices, et al. The unified management of distribution cable data resources and the fast and accurate positioning of line paths have been achieved. The practical application shows that the mobile GIS management system developed in this paper provides technical support for the planning and design of distribution network, line finding, et al. It improves the efficiency of distribution network emergency repair, and promotes the informationization and scientific process of distribution network planning and design, operation and maintenance management.
