Aiming at the problems existing in large rail weighbridge verification, a new rapid rail weighbridge verification solution was presented. Based on LabWindows/CVI development platform, software modularization, visual design was done, fuzzy self-tuning control algorithm was used to realize rapid loading and stability quick stabilizing. So the problem of high precision and fast calibration for large instruments was solved. Application shows that the software is superior in such aspects as reliability, stability, safety, operational performance. The measurement and control requirements of the electric control servo hydraulic rail weighbridge verification system are satisfied completely.
