Abstract

The invention discloses a railway vehicle running state identification method and system, relates to the field of railway traffic vehicles, and aims to provide the method for identifying the running state of the railway vehicle. The method can efficiently utilize the existing vehicle-mounted equipment to identify the running state and improve the running safety of the vehicle and the comfort of passengers. The invention also aims to provide the railway vehicle running state identification system. The system comprises an acceleration sensing system arranged on a vehicle body and a state recognition unit connected with the acceleration sensing system. The acceleration sensing system is used for collecting transverse and vertical vibration accelerations at the front end and the rear end of the vehicle body; and the state recognition unit is used for receiving the vehicle body vibration data collected by the acceleration sensing system and processing and analyzing the vehicle body vibration data to achieve recognition of the running state of the vehicle body. An identification result is transmitted to a cab monitoring center and a remote monitoring center through the network communication module, so that the running safety of a vehicle is ensured, and the comfort of passengers is improved.

Description

technical field [0001] The invention relates to the field of rail transit vehicles, in particular to a method and system for identifying a running state of a rail vehicle. Background technique [0002] During the operation of rail vehicles, real-time monitoring of the running status of the vehicles is an important technical means to ensure the safety of the vehicles and improve the comfort of passengers. When domestic high-speed EMUs are running at high speed, the factors that affect the safety of vehicles and the comfort of passengers mainly come from the wheel-rail contact relationship and the performance of suspension components. When the equivalent taper of the wheel-rail matching is too low, the bogie snaking motion will stimulate the suspension mode of the car body, and the EMU car body exhibits obvious low-frequency shaking; When the low-order elastic mode of the car body is excited, the car body of the EMU exhibits obvious vibration; when the anti-snaking damper fai...
