Monitoring system for device under high-speed multiple-unit train

Abstract

A monitoring system for devices under a high-speed multiple-unit train belongs to the remote monitoring field of devices under rail vehicles. The system is simple in structure and high in reliability, and well adapts to special environments. A common camera and a high-speed camera with the excellent performance are hung and fixedly connected under a train through camera rotary tables equipped with shields, and keep videoing and monitoring the running environment under the train and train key parts. The system can also be connected to a ground command management scheduling center through a wireless remote communication network, and can be controlled remotely by the center. The ground command management scheduling center can remotely control shooting directions and attitudes of a monitoring subsystem under the train, and can remotely obtain, analyze or store video contents shot by the monitoring subsystem any time. Shields of the system provide auxiliary illumination, temperature control and flying chip bump protection functions for the cameras to ensure that an environment monitoring device and a wheel track high-speed monitoring device under the train keep running reliably in a severe high-speed train running environment.

Description

technical field [0001] The invention belongs to the field of remote monitoring systems for off-board equipment of rail vehicles, and in particular relates to a monitoring system for off-board equipment of high-speed EMUs. Background technique [0002] Under-vehicle components such as traction motors, gearboxes, and brake discs, which are fixedly installed on the bogies of rail vehicles, sometimes experience unexpected failures. Auxiliary detection components such as electrical index parameters and built-in temperature sensors can only be used to judge the operating status of the faulty component, but cannot objectively and accurately reflect the wear or damage of the faulty component, which causes train drivers and remote dispatchers on the ground to It is difficult for the command personnel to fully evaluate the failure degree of the faulty component without stopping the vehicle, or to analyze the cause of the fault through video surveillance playback, which is not conduciv...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the limitation of various extreme environments and conditions such as flying debris impact and high cold when the space under the train is running, neither the train driver nor the remote dispatching and commanding personnel on the ground can directly obtain the equipment status and The video information of the operating environment under the vehicle makes it impossible to fully evaluate and analyze the dam
