基于模型驱动的高速铁路ATO系统TSRS设备软件开发

高速铁路ATO系统是在既有高速铁路列车控制系统基础上实现列车自动驾驶功能的列控系统,通过对ATO系统的地面关键设备TSRS进行软、硬件改造及升级,使其具备车-地通信功能,从而实现ATO系统的车站自动发车、区间自动运行、到站自动停车、车门开门防护、车门/站台门联动控制等智能化功能.本文研究了基于SCADE的模型驱动软件开发技术,并将其应用在车-地通信功能设计开发过程中.通过对模型进行验证、仿真测试和集成测试,最终验证了开发结果的正确性.

Model-driven Software Development Technology of ATO System for High-speed Railway

The ATO system for high-speed railway enables trains to operate automatically based on the existing train control system for high-speed railway.By transforming and upgrading the hardware and software of the key ground equipment TSRS of the ATO system so as to add trainto-ground communication function to the TSRS,the ATO system can realize such intelligent functions as automatic departure from station,automatic operation in section,automatic stop at station,door opening protection and train door/platform door linkage control.We make a study on the model-driven software development technology based on SCADE and apply it in the design and development process of TSRS's vehicle-to-ground communication function.The simulation test and integration test have been made to verify the model and the correctness of the development results is finally verified.
