Abstract

The invention provides a track vibration noise and dynamic deformation monitoring data field processing system and method. The system comprises a data acquisition module and a real-time analysis module. The data acquisition module is used for performing on-site real-time acquisition on various types of parameters related to track vibration, noise and dynamic deformation evaluation in a train passing time period; and the real-time analysis module is used for performing field real-time processing on the data acquired by the data acquisition module to obtain key parameters and indexes related to track vibration, noise and dynamic deformation evaluation. According to the system, the monitoring data are calculated in real time on site, key parameters and indexes of the monitoring data are extracted and returned, and huge original data are not required to be returned, so that the data transmission difficulty is reduced, and the problem that the vibration, noise and dynamic deformation of a rail transit rail are difficult to transmit and manage in real time due to huge data is solved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a system and method for on-site processing of rail vibration noise and dynamic deformation monitoring data. Background technique [0002] Urban rail transit has the characteristics of many small radius curves, high traffic density, high demand for vibration reduction, low rail system stiffness, frequent rail system stiffness transition, and many types of rail structures. With the increase of rail transit line service time, the train impact Under the action of factors such as fatigue and fatigue effects, the performance state of the track structure changes continuously, among which changes in the stiffness of the track system and the performance of track components directly affect the vibration reduction effect and the deformation stability of the track structure under the action of the train, which is related to the effectiveness of vibration and noise control, driving safet...
