Chassis fault detection early warning system and method of motor train unit

Abstract

The invention discloses a chassis fault detection early warning system and method of a motor train unit, belonging to the technical field of fault early warning. The system comprises a rail-side device, a rail-side machine room system and a background monitoring center system which are arranged close to a rail of a motor train unit, wherein the rail-side device and the rail-side machine room system transmit data through a wireless network, and the rail-side machine room system and the monitoring center system transmit data through a wired network; the rail-side device comprises an image acquisition device, a sound acquisition device and a speed measurement device and is used for acquiring images of a chassis of the motor train unit, acoustic signals of the motor train unit and motor trainapproaching, length and speed signals. The sound, the image, the speed and the length information of the motor train unit are collected through the rail-side device, and the information is sent to therail-side machine room system for calculation, so that the faults of the surface of the motor train unit chassis can be detected according to the image, the faults inside the device can be determinedaccording to the sound, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of fault early warning, in particular to a fault detection and early warning system and an early warning method for an EMU chassis. Background technique [0002] The EMU dynamic fault detection system can detect faults in the operation of the EMU, which is conducive to improving the safety factor of the EMU operation, and can automatically detect the components of the EMU to improve the work efficiency of the maintenance station; [0003] High-speed railways have a relatively large demand for EMU dynamic detection, and hope to improve the safety factor of high-speed railway operation as much as possible; [0004] Although there is currently a dynamic image detection system (TEDS) for EMU operating faults, the current dynamic detection system has a single recognition method, low recognition efficiency, and poor stability. Contents of the invention [0005] The purpose of the present invention is to provide...
