Abstract

The invention discloses an intelligent turnout aided design system. The aided design system includes a parts graphics library and a knowledge base module, a general layout quick design module, a parts design graphics generation module, a BOM table generation module and a system working area. According to the system, a general layout can be generated according to main design parameters such as turnout number, rail distance, and constraint rules; according to the design parameters, parameterized graphics of switch, frog, guard rail, basic rail, sharp rail are automatically generated; an inference engine based on RETE algorithm is responsible for completing the constraint analysis and constraint solving of turnout key parts; according to the actual use demands, the graphics library is expanded in a customized mode to generate new parts graphics; scheme comparison is conducted according to the preset knowledge base, and the best solution is selected by an expert decision support system. According to the intelligent turnout aided design system, the design cycle of turnout can be shortened, design error is reduced, and indirect overhead is saved.

Description

technical field [0001] The invention relates to the field of turnout auxiliary design, in particular to an intelligent turnout auxiliary design system. Background technique [0002] The turnout is the main structure of the railway track to realize the train transfer operation, and its technical level reflects the development level of a country's railway track in a relatively concentrated manner. my country's turnout industry has developed from scratch, from small to large, and its level has basically synchronized with the high-end level of the world's rails. With the advancement of the construction of high-speed railway lines and the development of railway track levels, the important role of turnouts has once again emerged. [0003] Nowadays, the scale of high-speed railway construction is rapidly increasing, and the research and development and design of traditional turnout products are facing many problems, such as the need for turnout products to meet the requirements of...
