| The electrified railway is developing quickly, so the workload of the power supply system is much heavier. One of the important problems we faced is how to improve the work efficiency and reliability of the power supply system.Geography Information System (GIS) towards to various application fields has become a technology applied in almost all projects, study and management fields based on space information. There are lots of figures, images, equipment data, design data and so on in the power supply system.In the paper, GIS has been used in the power supply system and a new management system has been designed.The space data and non-space data was managed by GIS in the paper. Through electing a suitable flatform, digital map and spatial database was built. The digital map and space database was built under Auto CAD and Arc Info. Non-space database was built under Visual Foxpro. Based on the request of the power supply, the functions include map-layer management, space query of equipment, record query and fast repair decision on accident etc. |
