Real-time detection system of state of train wheels based on LabVIEW

Virtual instrument (VI) is the computer technology and traditional instrumentation technology product of the combination, and is an important direction of development of the instrument. LabVIEW is a graphical programing language based on virtual instrument software development tools. This paper uses the LabVIEW 2010 point-by-point analysis of the database, sets up the state of the train wheels real-time detection system. It can carry on the examination in the train normal operation situation to the wheel's condition. As can be seen from the simulation, the test results are precise and rapid, with high practical value. © 2012 Springer-Verlag London Limited.
