Data acquisition system and monitoring system for rail train bearings and data acquisition method

Abstract

The invention provides a wireless data acquisition system and wireless monitoring system for rail train bearings. With the wireless data acquisition system and the wireless monitoring system adopted, data of the rail train bearings can be effectively acquired, professional analysis is performed based on complete data, faults are accurately positioned, fault root causes are analyzed, a fault degradation trend is monitored, rolling prediction of the service lives of the bearings is realized, andnon-planned shutdown is reduced. The wireless monitoring system comprises a temperature vibration sensor for collecting vibration and temperature data on each bearing, a train TCMS system for obtaining rotating speed data of the bearings, a train bearing detection system for controlling, collecting and obtaining the vibration and temperature data on each bearing, and a cloud platform server for storing the data. The system further comprises an expert diagnosis platform used for analyzing data, positioning faults, analyzing fault root causes, monitoring fault degradation trends, predicting equipment faults in advance and achieving rolling prediction of the service lives of the bearings. Meanwhile, the invention further provides a wireless data acquisition method capable of using the wireless data acquisition system and the wireless monitoring system for the rail train bearings.

Description

technical field [0001] The invention relates to the technical field of urban track monitoring, in particular to a data acquisition system, a monitoring system and a data acquisition method for rail train bearings. Background technique [0002] Urban rail transit ("urban rail" for short) is a means of transportation with large capacity, fast speed, low energy consumption, less pollution, high reliability, and good comfort. As of the end of 2013, my country has approved rail transit construction plans for 36 cities, with a mileage of about 6,000 kilometers. The demand for urban rail trains will reach more than 19,870, and urban rail transit has entered a new stage of vigorous development. [0003] With the opening of more urban rail lines, the service quality and service efficiency of urban rail transit have received more and more attention. Whether the train is on time is directly related to people's normal life and work, and even has a great impact on ground traffic. In rec...

Problems solved by technology

For most of the components on the train, maintenance personnel need to frequently check and measure, and sometimes even need to disassemble to confirm the working status of the components, resulting in a lot of extra work, wasting manpower, material and financial resources
