High-speed train running gear fault diagnosis and remote monitoring system based on Internet of Things

Abstract

The invention relates to a high-speed train running gear fault diagnosis and remote monitoring system based on Internet of Things (IOT). The system provided by the invention comprises vehicle-mounted sensors, a signal conditioning and filtering device, a central processing system, a data input and output interface device, a vehicle depot information collection system, a nationwide train maintenance system and a man-machine interaction device. With the arrangement of a plurality of the vehicle-mounted sensors, accurate fault identification and positioning of key equipment of running gears are realized, prediction of faults is realized, train operational risks are reduced, remote diagnosis of faults is achieved, fault diagnosis cost is lowered, and fault diagnosis cycle is shortened.

Description

Technical field: [0001] The invention relates to a fault diagnosis and remote monitoring system for the running part of a high-speed train, in particular to a fault diagnosis and remote monitoring system for the running part of a high-speed train based on the Internet of Things. Background technique: [0002] With the continuous improvement of the speed and mileage of high-speed trains in my country, the safety and reliability of train running parts have become extremely important. The abnormal state of the key equipment of the train running part is one of the important hidden dangers to the safe operation of the vehicle. Severe and sudden abnormal conditions can cause malignant accidents such as vehicle derailment or even overturning, causing incalculable losses to society and personnel. Common abnormal conditions of the key equipment of the running gear include bogie instability, excessively high bearing temperature, scratches and imbalances on the wheelset tread, bearing crac...

Problems solved by technology

[0003] At present, only manual measurement can be used to monitor the state of the running part. In manual measurement, manual experience plays a dominant role in diagnosis, and human factors are relatively large.

Moreover, hidden dangers of equipment cannot be found, and early failures of vehicles cannot be found in time, resulting in untimely maintenance and poor real-time performance

Manual measurement cannot fully record the operating status and fault information, and the analysis of faults cannot be systematic

[0004] The Chinese patent (application) number is 201110381590, titled "High-speed train intelligent system and its communication method", including on-board intelligent sensing nodes, on-board parts of train control system, on-board data center, train-ground broadband communication system, ground data center, host Factory and / or bullet train base application systems, Internet of Things collection terminals, broadband application systems, one or more sensors, and I / O interface devices realize the functions of self-testing, self-diagnosis, and self-decision-making of the train system, but this intelligence system, it is impossible to realize the diagnosis and online monitoring of all trains across the country, so the whole system needs to be further improved
