Method for acquiring and transmitting fault signals of rail traffic vehicles

Abstract

The invention discloses a method for acquiring and transmitting fault signals of rail traffic vehicles. The method comprises the following steps: acquiring environment energy from an external environment, and converting the environment energy into electric energy; supplying power by using the electric energy and then acquiring traveling information, and carrying out fault diagnosis according to the traveling information on the basis of astronomical clock synchronous data stream and/or variable speed reconstructed data stream to obtain a diagnosis, wherein the traveling information comprises temperature information and accelerated speed information of a diagnosis object of a vehicle traveling portion; and judging whether faults exist or not according to the diagnosis. By the method, the process complexity of product loading can be greatly simplified, and rapid retrofitting of an existing vehicle is implemented. The invention further discloses a device for acquiring and transmitting fault signals of rail traffic vehicles. The device has the foregoing beneficial effects.

Description

technical field [0001] The invention relates to the field of rail transit, in particular to a method and device for collecting and transmitting fault signals of rail transit vehicles. Background technique [0002] With the rapid development of science and technology, a large number of urban rail transit and high-speed rail transportation have gradually become an indispensable part of people's lives, and subway trains and high-speed rail EMUs are playing an increasingly important role in society. [0003] The popularization of rail transit has also brought about the problem of faults in the running part of rail transit vehicles, and the fault diagnosis technology for the running part of rail transit has emerged as the times require. In the prior art, the method of wired connection is usually used to detect the fault of the running part. Since the wiring on the bogie is difficult and the process is complicated when the vehicle fault diagnosis product is loaded, it creates a hu...

AI Technical Summary

Problems solved by technology

In the prior art, the method of wired connection is usually used to detect the fault of the running part. Since the wiring on the bogie is difficult and the process is complicated when the vehicle fault diagnosis product is loaded, it creates a huge problem for the state monitoring and fault diagnosis of the running part. obstacle

Especially in the prior art, fault diagnosis by way of wired connection cannot realize rapid installation of rail transit vehicles already in operation.
