Abstract

The invention discloses a railway dynamic detection system, comprising a data aware unit, a data acquiring unit, and a data processing unit. The system can complete fault real-time diagnosis of unbalanced rotation and misaligned rotation of a bogie wheel shaft, real-time monitoring of working conditions of a wheel set traction motor bearing of the bogie, a bogie wheel set bearing, and transmission gears of a traction motor when a rolling stock is in an operating state, and the system can diagnosis faults which is possible to occur in real time. Meanwhile, using real-time transmission characteristic of vibration, through obtaining vibrating impulse signals generated by railway track damage when the rolling stock is operating, and vibrating impulse signals generated by railway subgrade defects when the rolling stock is operating, the system monitors the railway track damage and subgrade defects. Compared with conventional railway detection systems, the system not only can comprehensively diagnosis the rolling stock's faults, but also has high detection efficiency.

Description

technical field [0001] The invention relates to the field of running safety detection of railway locomotives, in particular to a railway dynamic detection system. Background technique [0002] Train is an important tool for traffic and transportation. It has the characteristics of large transportation volume, fast speed, convenience, high safety factor, fixed line and unified grouping and operation of time and stops. How to adopt effective management and technical means to ensure the safety of railway locomotives, railway tracks and railway subgrades, so as to ensure that the trains enter the running state without failure and hidden dangers, and prevent personal and property safety accidents have become the focus of railway work. [0003] Taking the railway rolling stock as an EMU train as an example, the railway inspection includes three parts: EMU safety inspection, railway track damage monitoring and railway subgrade disease monitoring. At present, the safety detection o...
