The Research And Implement Of Railway Continuous Transmission Lines CAD System

Railway continuous transmission lines is an important part of railway power system. The traditional design of continuous transmission lines are often based on a common CAD system. In the design process, it's difficult to integrate the expertise to design system. So the automation degree of the system is not very high, and the veracity is poor, and the validation and statistic working is difficult to be along. Therefor, this paper combined the project of "railway power lines CAD design software", and researched and developed a continuous transmission lines CAD system. This paper based on object-oriented design ideas and combined power lines expertise, and based on user-defined figure technology to make use of attribute of objects to store the design parameter. Based on this, according to the formula of the power lines design, raised the automation degree of design platform, reduced the labor intensity in the maximum, and raised the criterion and veracity. With the help of the system, designer can complete the design quickly and exactly, and it can also create the statistic report forms of the project. It's very significant for this system to improve design efficiency.At first, we discussed the problem in the present railway continuous transmission lines designing and the deficiency of the present CAD system, and raised the necessity and significance of the railway continuous transmission lines CAD system. Then, according the requirement of the designing, and the railway continuous transmission lines standard, we planned a model which sketched the frame of the system and raised the function of every part of module. And then, we confirm every function of the system based on the character of railway continuous transmission lines designing. The paper introduce the arithmetic and realization of some main function. At last, we introduce the application of the CAD system in the railway continuous transmission lines projects of practice. With the test of practice, this system is greatly helpful to the designing and statistic of railway continuous transmission lines project. Finally, we sum the shortage of this system up, and have the prospect on the future work.
