Verification And Automatic Code Generation Analysis Of Trackside System Based On The Simulation Model

Since China has entered the era of high-speed railway, advanced technology such as computer, communications and automatic control have been used in Chinese Train Control System more and more. For CTCS is a safety-critical system, on the basis of ensure the train’s safety running, how to continuously improve the speed and efficiency of the train has become the key point of railway research. So, we need do further research of the CTCS-3Train Control System.This article rely on the CTCS-3Train Control system simulation test platform, this platform is used for the systematic study of CTCS-3train operation control system, program comparison and experimental simulation data line transformation for the renovation of equipment and wiring the driving conditions to provide a simulation test in the laboratory environment.This paper carried out depth research of the trackside subsystems, which is the key equipment of the platform. Use SDL modeling trackside subsystem to analysis and validation, and finish functional simulation in computer software environment. The main contents are as follows:First, do analysis of trackside subsystems system functional requirements to determine the other major interaction between trackside subsystems and platforms, and simulation function of trackside simulation.On this basis, use the SDL language to make graphical models of trackside subsystems from the system diagram level, function block diagram level and process diagram level, then do co-simulation and traverse validation by using the Telelogic TAU, then verifying the SDL system of the model is correct.Finally, convert the SDL system model to C language code automatically and eventually used in the CTCS-3Train Control system simulation test platform trackside subsystem. The test results show that, the automatically generated code based on the trackside model have achieved the expected goals that the emulation subsystem should have, and it also meets the requirements of CTCS-3Train Control System Simulation Testing Platform.
