Study on Technology of Automatic Generation of Indoor and Outdoor Interlocking Construction Drawing of Signaling System in Urban Rail Transit

The preparation of signaling system construction drawing has become a barrier to project site construction due to such characteristics as long time span, great review difficulty, and low working efficiency, etc. With respect to this issue, the paper proposes a systematic way of automatic construction drawing preparation developed on the basis of a diagram element library. The system combines basic configuration data with the diagram element library and makes it possible to export a whole set of indoor or outdoor construction drawing with consideration of interface layout requirements from the user. Good economic benefits may be obtained compared with traditional manual plotting.
