Embodiment Construction

[0030] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0031] The method provided by the invention comprises:

[0032] Step 1: The sensor collects the analog signal of the operating state of the high-speed train braking system in real time, and converts the collected analog signal into a digital signal;

[0033] Step 2: The information preprocessing unit amplifies and filters the converted digital signal, and transmits the processed digital signal to the self-diagnosis unit and the vehicle-mounted wireless transmission platform;

[0034] Step 3: The self-diagnosis unit conducts a comprehensive analysis based on the processed digital signal to obtain the diagnosis result of the operating state of the braking system, and sends the diagnosis result to the vehicle-mounted wir...

Abstract

The invention discloses a fault diagnosis device and a diagnosis method for a high-speed train braking system in the technical field of train operation control. The method includes acquiring and processing signals of operation states of the high-speed train braking system in real time; then obtaining diagnosis results of the operation states and sending the results to a ground subsystem; and the ground subsystem performing sort management and obtaining comprehensive diagnosis results for decision of maintenance policies. The system comprises a vehicle-mounted subsystem and a ground subsystem, wherein the vehicle-mounted subsystem comprises a sensor, an information pre-processing unit, a self diagnosis unit, a train communication network (TCN), a vehicle-mounted wireless transmission platform and a vehicle-mounted industrial Ethernet; and the ground subsystem comprises a ground wireless data access layer, a ground center analysis layer and a ground center comprehensive maintenance management decision-making layer. The fault diagnosis device and the diagnosis method can diagnose faults of the train braking system efficiently, rapidly and accurately, and a safeguard mechanism is provided for reliable operation of high-speed trains.

Description

technical field [0001] The invention belongs to the technical field of train operation control, and in particular relates to a high-speed train braking system fault diagnosis device and a diagnosis method. Background technique [0002] As a whole composed of complex technical equipment, operating in a complex environment, and completing displacement services with complex spatio-temporal distribution characteristics, high-speed trains are a complex networked giant system. Once it fails, it will cause great harm. Moreover, due to the many components and various detection parameters of high-speed trains, the types of faults that occur are also complex and diverse, including: sudden faults, cross faults, combined faults, and chain faults. And different reasons may also produce the same fault phenomenon, which makes the fault diagnosis and maintenance of high-speed trains more difficult. At present, the maintenance of high-speed trains basically depends on the experience of rele...
