Design And Development On The Traction Drive Testing Device

With the rapid development of economy, Chinese railway has entered the era of high speed. Chinese introduce and absorb the advanced experience of Japan, France, Germany and other countries in the high-speed railway technology successfully, and produce high-speed train of the speeds of 200 kilometers to 250 kilometers per hour completely independent on domestic innovation, design and develop EMU of the speed of 350 kilometers per hour, develop the operation speed of 380 km of new generation of high speed train, out of a "China type High-speed Rail" road of development, realize the great leap forward development. The core components of high speed train traction electric drive system and network control system has achieved a 100 percent "created in china". For the high-speed EMU operation, long distance continuous process of high-speed operation, traction drive system working conditions are very important, whether the system normal operation can not only influence the train comfort, but also affect the traction and the brake performent, and even affect the safety of the train.At present in the rail transportation industry, data acquisition of train running state and monitoring functions recorded and displayed by the TCMS sub network control system of vehicle and traction system, braking system, gating system and other system directly. They are the key parameters on the part of the data acquisition and recording, its function can not meet all the key operation parameters on the traction drive system for real-time monitoring and recording; In order to ensure the reliability and safety of sustained high-speed train long distance running in the process, aiming at the status quo of rail transit industry, the advantages and disadvantages of the related operation data of traction key parts of the transmission system and the field of traction drive unit operation conditions and existing network control system, draw the conclusion that it is necessary to develop trace monitoring system of intercity EMU traction drive system.(1) System design principles introduction and performance requirementsBased on virtual instrument,it is presented the basic scheme of train test device on drive system and detailed classification of the main function of the system and the monitoring signal. According to the function requirement of the test system, taking into account the vehicle test system for anti vibration, anti interference, portable and many other features, the system is adopted embedded CPCI bus structure in the design. The hardware design of the performance of the system are introduced in detail, finally introduced the classification of detailed classification and main function and monitoring signal of each part of the.(2) System hardware platform designThis chapter mainly introduces the hardware structure design of traction control drive system test device host composition and data acquisition and control part of the Test system adopts the control host computer and data acquisition parts in the part of hardware, including power supply board, wireless communication board, A/D conversion board, DIO board, CPU board, voltage transformer, Holzer sensor, temperature sensor and other equipment. On the selection of all kinds of sensors and technical parameters were designed, and the transmission path of all kinds of signals and Adjustment method is introduced.(3) System software platform designThis chapter focuses on software architecture and design subroutine of testing device of the traction system. The software design using LabVIEW development environment system includes the background processing and foreground data display function. The background data processing module includes the realization of the traction mechanism of all kinds of signal acquisition, information processing and information storage function. The front data display module comprises a parameter design, real-time display and off-line analysis module.The software design of the system is divided into the on-line real time data processing and off-line data processing. The on-line real time data processing parts mainly completes the real-time signal acquisition, real-time display and real-time storage of records and other functions. The off-line data processing parts mainly includes the playback of the historical data and reproduce (including curve), electrical signal analysis and power harmonic analysis of electrical equipment, EXCEL query and analysis of existing data file, chart and print and other functions, finally through the wireless communication technology to realize the remote access to the collection data.(4) Design theory and key technologyThis chapter is mainly about the research on the key technology of the traction system of the testing device. According to the analysis of running environment of the scene of the traction drive system, the latest signal integrity and electromagnetic compatibility theory and design method is adopted, obtained the feasible design technique and methods.(5) System verification and ProspectsThe chapter is a conclusion on the research results of traction drive system test device.the test results show that it provides a fast, accurate, intelligent and automated testing approach of the system for testing technical staff, reaches the preliminary design requirements of the performance indicators. At the same time, the test system were only completed the measurement under the laboratory environment, thereafter the device will be real-time monitoring and testing to the actual operation of the EMU on the testing states, the reliability of the continuous improvement of hardware circuit and software environment.
