Research And Realization Of Running State Test System For Qinghai-Tibet Generator Car

With the completion of Qinghai-Tibet railway traffic in Tibet plateau, snow area with history of no railway was ended, inland large personnel exchanges and transport of goods to Tibet become a reality, and far more efficient, economic, safe than the original land transportation. Because of the Qinghai-Tibet plateau hard climate natural environments, severe cold and hypoxia, railway departments using a special type of 25T Qinghai-Tibet plateau railway transportation for passengers. At the same time, because of Qinghai-Tibet railway now isn't electrified railway,25T Qinghai-Tibet plateau railway transportation need a great lot of power, each passenger train was equipped with a generator car, providing electricity power to passenger train. The generator car for Qinghai-Tibet plateau railway also is a special type of 25T Qinghai-Tibet plateau generator car. Qinghai-Tibet generator car needed to examine after off line repair, but no effective approach for the maintenance testing. Mere artificial inspection operation and personal maintenance experience significantly can't adapt to the railway departments production needs and safe operation of passenger trains. Based on this, combining with Lanzhou railway station, join research and develop the Qinghai-Tibet generator car running state test system.This topic focus on the generator car running state real-time monitoring and fault diagnosis research, using water resistance load test device, through adjust water resistance to simulate the generator car online running under different conditions, detecting diesel engine's speed, Oil pressure, water temperature and generator voltage, current, generator car output voltage, current and so on. After process the testing data can judge the generator car reliability, overall characteristics and power whether meet the railway departments.This paper describes the structure and working principle of Qinghai-Tibet generator car, reviews generator detection monitoring technology, the development situation of research on gererator car running state test system on the world and explaining innovation and realistic significance of this system. Puts forward Qinghai-Tibet generator car running state test system, and research on this corresponding work.Through analysis the difference between common gererator car and Qinghai-Tibet generator car, puts forward the system overall scheme which appropriative, high degree of automatic, multi-parameters, fault detection function, and on this basis to actualize the system hardware and software design, installation and commissioning.This system hardware mainly includes water resistance testing equipment and testing work station. Among them, water resistance test device is the main component of this system, testing work station including data acquisition module, control and operation module, IPC communication module. Testing work station connects the test system with Qinghai-Tibet generator car. The hardware part's main task is manual or automatic operation water resistance test device under different working conditions, and transmitting various testing parameters realtime and efficiently to software system, for Analysis and processing.This system software adopts kingview and VB, IPC software system mainly completes test process control, monitoring and testing data realtime display, historical records and statements inquires, test process trend curve print drawing, failure analysis, communication networking functions and Etc. Since the configuration software and IPC, reduced the cost and programming work, and also has good portability and expansibility.Through analysis this system in actual application, the subject completed Qinghai-Tibet generator car test system with complete functions, simple operation, safe and reliable, convenient and flexible characteristics, improving Qinghai-Tibet generator car repair and test automation degree, reducing the maintenance and test of man-made factors and labor intensity, improving the precision and parameters of the test results, the realization has good social and economic benefits.
