| Thesis on computer interlocking system components, functional structure research, From the actual needs of school training and drills, Comprehensive UML modeling language method, VC ++ Development Tools, Design and implement a complete, consistent, consistent with computer simulation system interlock signal system requirements. Meanwhile, the proposed algorithm interlocking table is automatically generated, minus the tedious manual entry interlock table work. On completion of the work includes the following aspects:Interlocking system structure, working mode are analyzed, combined with UML use case diagram couplet lock core business(including train route business, shunting route business, guide business route, switch operation, accident unlock business, business of interval direction, three check business) were analyzed in detail, and the use of couplet of the sequence diagram to analyze and describe the timing of the software of locks, to lay a foundation for the follow-up work.The overall structure of the simulation system is designed, and the core data flow is analyzed, and the basic modules are completed. On the basis of module division, the function, input and output of each module are described. The approach to manage a complex algorithm in interlock were described, the route selection, route registration, opening, closing and signal signal to unlock several state and state transition route chart.The core data structure of simulation system software to achieve the antithetical couplet lock is designed, including array definition, definition of data structure and macro definition.The function of the whole interlocking simulation system is verified.The system is put into use, functional and reliable, the effect Zhuoqun, both to meet the training school, they need to exercise, but also save money, create efficiency. |
