Research Of Simulation On ATP Human-machine Interface Based On MDA

Nowadays railways experience a fast development in China. The control manner of railways has changed from the way of wayside signal aspect to the way that according to the information of train speed from wayside equipment, train control system exercises control over the train and displays the information on human-machine interface to the driver. ATP Human-machine Interface is the only connecter between train control system and the driver, plays an important role in railway train. Therefore the simulation on ATP Human-machine Interface is of great importance.The paper introduces the based principle of MDA, states the practical significance of using MDA in interface simulation. The paper draws MDA into the simulation research of ATP Human-machine Interface for the first time and raises an simulation method which follows MDA and fits the simulation of ATP Human-machine Interface to realize the functions of ATP human-machine interface.Firstly, based on MDA, the paper analyzes the requirement of ATP Human-machine Interface with User Case View and Sequence View of UML.Then, on the base of requirement analyze, the paper raises the ICV model as the Platform Independent Model of ATP Human-machine Interface, and describes the model's static and dynamic attribute with UML.Lastly, while building Platform Specific Model, the paper chooses the LabVIEW as the platform, draws up a detailed transform rules. The transform rules are separated into two parts. One part realize the communication by the auto-transform way. According the definition of Platform Independent Model, the other part built the modules of Platform Independent Model and realize contact among the modules by the manual-transform way. Finally realize the simulation of ATP Human-machine Interface.Following the MDA method, the paper shortens the development period, improves the system accuracy and strengthens the system portability. The emulated ATP Human-machine Interface satisfies the requirements, is used in the evaluation and research of CTCS-3.
