Expert System Based On Simulation And Testing Platform Of High-speed Train Control System

Now it is a stage of rapid development for Chinese high-speed railway. Chinese high-speed railway mileage ranks highest in the word. The high-speed railway of Beijing to Guangzhou is the world’s longest high-speed railway, and the high-speed railway of Beijing to Shanghai is the worlds longest and the most advanced high-speed railway once built. Planning and construction of high-speed railway continues. Such a large-scale, rapid railway construction is not at the expense of quality and safety in exchange. Until now the world there are many countries used China railway technology, visible quality and safety High-speed Rail in China is guaranteed. But now the high-speed rail train control system safety completely through on-site testing to complete, need to spend a lot of time, manpower, material and financial resources. And there are the following problems: the test sequence did not do optimization, test termination often appears in the field test, the test result in a waste of valuable time; analysis of test data and results are highly dependent on the train control experts, expert data analysis may lead to a limited number, long time, low efficiency, but also may be due to analysis experts work bring mistakes. To solve these problems, this paper mainly do the following aspects of the research:1、based on the simulation of high speed train control system test platform design theory and technology XMSF. XMSF is extensible modeling and simulation framework, using it to build high-speed train control system simulation test platform can be implemented using different middleware; access equipment in different geographic locations; on the future of the new function support. In order to give full play to the advantages of the simulation platform, this paper puts forward the methods to solve the contradiction between time ratio, simulation and real-time simulation efficiency, improve the simulation efficiency at the same time, to ensure the accuracy of the simulation results. At the same time the design of test sequence XML script format, convenient docking and expert system.2、the design of high speed railway vehicle test case analysis expert system. The expert system realized the connection with the high-speed train control system simulation test platform; summarizes the characteristics of high-speed train control system test case and test sequence, according to the features of design expert system rule base and reasoning machine. The realization of automatic analysis of test cases in the test sequences.3、introduces the software interface and function of the high-speed train control system test analysis expert system. Through the above research, in order to achieve the simulation test platform, test sequence optimization, reduce site due to improper test sequence error; through the design of expert system, improve test case analysis efficiency, reduce the labor intensity of experts.
