Design And Implementation Of The Route Table Serarch Generation System Based On Computer Interlocking

With the comprehensive of high-speed railway construction and gradually speed, therailway system on the CI system reliability and security of the increasingly high demand.Compared with the former based on the structure of the complex relay control, computerinterlocking system has a higher security and reliability.However, as an interlocking system data sources, route table (also known asinterlocking table), most still rely on manual preparation of the audit, not only the efficiencyis low, and easy to make mistakes. Therefore, how to develop a safe, reliable, fast,convenient generation system configuration through a complete system attributes, so thatthe system can output a correct and complete to the existing interlocking system can beused into the road surface is the interlock system need to address the most urgent task.In this paper, the learning of computer interlocking technical conditions, the transversecompared with longitudinal analysis of related systems within the areas of expertise,combined with the design specifications and design features of existing computer-basedinterlocking system of the Ministry of Railways, the station through the design of graphicalinterface, modify the signal the data structure of the device, built to generate a visualizationinto the road surface conditions based on computer-based interlocking system.The main functions of this system are described below.(1) the definition of basic graphing and related graphics portfolio, simulation to mapout a signal, section switches, indicating lights, buttons, interlocking system of basicequipment graphics, plan design and drawing of interlocking station station function. Interlock system is responsible for data related to the development station designers toquickly build a visual station model through the system, to match the original blueprints,WYSIWYG visual development process.(2) through the analysis of different types of signal equipment, the definition of theconfiguration properties, depicting interlocking signal equipment, the parent class, specificdevice (signal, switches, section, etc.) for the subclass to inherit relations the main classdiagram of the signal equipment structure, and according to the data structure from thestation graphic description of the station topology changes described, for the generation oflate into the road surface provides the basis of reliable data acquisition and data analysisfoundation.(3) of the system through the analysis of the topology of the station, always end buttonfor search approach section, the turnout given the anti-traverse hostile signal and judgment,and ultimately the automatic generation of basic route table to grow in the road surface,and other functions and do the station graphics yellow belt display. Changed in the pastproduced manually route table is time-consuming audit boring route table, do all traversestation elements and all judgment, correctness and reliability of the route table preparationresults.This system and other simple route search algorithm, the entire process of interlockingstation data from the initial station design to the signal device properties defined to thepreparation of the final route table, the three organic combination together to make it atthe same time can be completed within a system, data sharing and interoperability. Not onlysaves the time of the artificial preparation of the road surface, at the same time, the archiveof the entire data, the actual publishing process simplified, and the late review of the data,as well as the station of transformation provides a great convenience.
