The train control system is the key technology and core equipment in the high-speed railway signal system.With the rapid development of China's high-speed railway signal technology,the signal equipment and related technologies are constantly updated.The CTCS-3 train control system is suitable for high-speed lines with a speed of more than300km/h,which is the core to ensure high-speed and safe operation of trains.With the development of China's Automatic Train Operation(ATO)technology,its application in the CTCS-3 train control system is of great significance for the independent research and development of China's train control system.This paper draws on the experience of successful application of ATO technology in CTCS-2 train control system,combines ATO technology with CTCS-3 train control vehicle equipment,studies the ATO algorithm applied to high-speed rail signal system,and the implementation of the CTCS-3+ATO On-Board simulation test system is described in detail.The specific research contents of this paper are as follows:Firstly,the structure and function of CTCS-3 train control system and ATO system are introduced.Based on this,the CTCS-3+ATO train control system concept is proposed,and the structure changes and functional requirements after applying ATO technology is analyzed.Secondly,the overall design of the On-Board simulation test system is proposed.The system level is divided.The structure,function and implementation scheme of the test system are introduced.Based on the analysis of the functional architecture of the On-Board simulation test system,the simulated driving interface module,information receiving and processing module,overspeed protection module,train operation calculation module and train operation simulation module were specifically designed.Then the software implementation algorithm of CTCS-3 train control system carrying ATO technology is expounded.The genetic algorithm is applied to the test system for the control train operation function in the simulation test system,and compared with the traditional algorithm.Finally,the Microsoft Visual Studio 2012 system platform is used as the development platform of the vehicle simulation system.The computer simulation and object-oriented development method are used to complete the development of the CTCS-3+ATO train-controlled On-Board simulation test system and the main functions of the vehicle simulation system.
