Study And Implemention On Integrated Railway Signal Design System

Signal design is an important part of railway survey and design.Chinese railway construction has entered a new stage of development by leaps and bounds,where after, the contradiction between existing insufficient design ability and rapid growth of signal design tasks increasingly come out. There is urgent need to improve production efficiency. On this background, this paper presents railway signal design integrated system to change traditional design pattems of signal works, and provides research mode of realization of intelligent design and automatically drawing for professional signal.This paper introduces the contents of signal design. Based on in-depth analysis requiretments of railway signal integrated design system, combined with the signal design specifications and the existing design pattens, paper develops the principles of system design. At guidance of these principles, paper presented design scheme for whole system structure:with modular design approach, it divides signal design into a number of aspects. Each aspect is a independent module which was new development or an existing software, and all aspects are combined organically. To ensure the accuracy of data in transmitting between aspects. It uses multi-level feedback mechanism that combined artificial verification and system verification. Meanwhile, this paper discusses the design ideas and implementation methods of the interlocking table generation software system, proposing deficiency and improvement methods. And it elaborates on the outdoor wiring cable design software’s design idea and criterion, functional requirements and algorithm. Based on outdoor cable wiring software’s testing, shortcomings are discussed. The reliability, efficiency and application of the entire system are analysised and prospected.The software program is implementated by VBA (Visual Basic for Application) in this thesis. Currently,in a laboratory environment, the test results show that the outdoor wiring cable design software’s view of user-friendly, visually, with good interaction has achieved the desired research goals.
