Study Of The Testing System Of Titling Train Based On DSP

Nowadays, the railway department in our country has encountered many challenging difficulties. The continuous improvement of the train speed results in the high requirement of the quondam railway condition. Therefore according to the condition abroad, the development of the tilting train, designed by our own country, has been placed the first position on the way of the improvement of the train speed.The research of titling train testing & control system is the science and technology development item of the railway ministry. Considering the engineering application, DSP technology, the main direction in the field of digital signal processing, is discussed in this paper.The technology of the DSP involves in many kinds of science and has been widely applied in many fields such as communication, signal processing, auto control and military. On the grounds of the perfect capability and availability of DSP in the digital signal processing, the choice of DSP as the core component in the testing system is wise and advisable. And the TMS320C4x serials of Texas Instruments (TI) company comprise of the most important parts in the whole floating DSP products.The main problem the paper tries to resolve is the application of the available Digital Signal Processor (DSP) in the testing system of the tilting train based on the current digital signal theory. In the paper the constitution of the testing system in the tilting train is discussed, as well as the design of the front access, the subsystems performing the function of interruption, resetting, saving, communication and debugging. Furthermore the analysis of the Signal Integration (SI) is considered, which has improved the anti-noise ability and the reliability of the system. At the end of the paper, the driver program, working in the basement and passing the debug of the whole testing system successfully, is mentioned.In the paper the composition and the different projects of the respective subsystems are ideally analyzed and compared. In terms of the advantages and the disadvantages, also based on the principle of the utility and availability, a favorable project is applied in the system. The feasibility of the design is proved by the result of the simulation.The development of tilting train is one of the national crucial programmers. And the testing system is so important in the whole project that its effective design attaches to the security of the tilting train running.
