【Abstract】 CTCS-3, which means the three level of Chinese train control system, is the core of guaranteeing the operation security and improving the conveying efficiency of high-speed railway, and the nerve center of high-speed train. Around the special requirements of testing and assessment, this dissertation researched on the visualization of CTCS-3 testing and simulation platform. It studied-the key technologies and the implementing methods of visualization which were the train control scene visualization and the operation process visualization.This dissertation firstly analyzed the specific requirements of CTCS-3 visualization system and the performance index parameters of train visual simulation. Introducing the multi-resolution modeling theory into the system design, a visualization simulation supporting architecture was proposed by combining the HLA/RTI federation mode and TCP/IP communication mode, which fulfilled the communication exchange and the achievement of the visualization system in the CTCS-3 testing and simulation platform.For the diversity of line data’s representation in the visual scene of the CTCS-3 testing and simulation platform, the C3RD line data representing method of high railway was put forward according to the specific analysis of the train control data and the 3D visual description. Based on the multi-resolution modeling method of meta-model theory in visualization scene, this dissertation realized the space structure design and the CTCS-3 visual scene description.There are different requirements for the train visual observation and level of detail demands in the CTCS-3 testing and simulation system. According to the specific analysis of the train running behavior and multi-resolution theory, this dissertation raised a visual train generating method of different resolution. Meanwhile the aggregation and disaggregation process between different resolution models were analyzed in detail. After all, the availability of this method was certified by case study.Through the organization characteristic analysis of high-speed railway scene, this dissertation solved the difficult of high speed railway virtual scene modeling by putting forward a high speed railway scene modeling method based on the 3D scene longitudinal sectioning with the accumulating distance as parameter, and the lateral scene organization with the scene graph rule. The tracks and subsidiary facilities were intelligently generated through the extraction of key tracks and characteristic points. Combining the high speed and human vision identification, the optimizing modeling method of railway scene was proposed based on the velocity and vision characteristics. The virtual scene modeling of Jinhu high speed railway was accomplished with this intelligent method.On the demand analysis of visual simulation in the CTCS-3 train control system, the control algorithm of train visual simulation was studied under the CTCS-3 rule. This dissertation raised the dynamic path-finding algorithm based on graph theory and the generation maintenance algorithm of train group based on visual track circuit. It was accomplished by the 3D visualization simulation of long-distance railway in CTCS-3 train visual simulation combined with the blocked data dispatching method related to the multi-resolution scene.Lastly, the Model Driven Architecture (MDA) theory was introduced into the research of CTCS-3 operation process information visualization. According to the key modeling process of EDA, it was achieved by the CTCS-3 operation process information visualization. Based on the improved GUI model, the ACI (Core Adapter-Interface Controller-Interface) model was proposed, which is suitable for the process information of visual interface. And the transformation process was described in details between the key models with the UML language.更多还原
