Design And Implementation Of Automatic Train Operation Testing System In Urban Rail Transit

Automatic Train Operation is an important part of the automatic train control system. It constitutes the signal system of urban rail transport with Automatic Train Supervision and Automatic Train Protection and it is also the basic equipment of urban rail transport.The Automatic Train Operation can choose the best operating conditions according to the set operating graph and the order of Automatic Train Supervision. It accomplishes the speed adjusting and energy-saving in the course of traction, brake, cruise and door controlling. The Automatic Train Operation system can replace and standardize the train operation, it helps drivers to accurately implement the travel plan, increase the traffic efficiency, make the passengers comfort and save the energy.At present, the domestic Automatic Train Operation system is introduced by foreign equipment and technology, so develop the Automatic Train Operation system is not only to have our own intellectual property, but also to create basic conditions for Automatic Train Control System. However, if we make the train operation test in the real circumstance, it is a big prodigality for both human and material resources, and it is also unsafe. So using the computer to simulate the complicated circumstance of train moving, to study the theory and methods of train operation and control, is really an economical, reliable and safe method.The thesis research on the theory of traction calculation model of rail transport and then constitutes the traction calculation and circumstance model of urban rail transport. It makes use of computer simulation technology and advanced virtual instrument technology to develop simulation and test system of Automatic Train Operation. It uses the virtual equipment PXI which is a new platform in the field of test and measurement. The software platform is Labview 8.2 which is a professional and graphical programming tool. The test system not only can be used for the test of Automatic Train Operation system, but also played a very important part role in designing and developing the Automatic Train Operation.As a result, the Automatic Train Operation test system can better simulate the urban rail transport and accomplish a variety of test tasks; it really significant in the development of .Automatic Train Operation.
