Train working condition on-line monitoring method for rail transit

Abstract

The invention provides a train working condition on-line monitoring method for rail transit, which belongs to the technical field of rail transit. In the working condition on-line monitoring method provided by the invention, the train failure can be divided into primary level, regional level and central level, and status data can be transmitted to the ground through a train-ground wireless communication transmission system, so that the primary level failure is analyzed and handled by a vehicle-mounted failure information preprocessor on a train correspondingly, the regional level failure is analyzed and handled by a regional information processor on the ground correspondingly, and the central level failure is analyzed and handled by a ground central information processing system on the ground correspondingly. Therefore, different types of failures can be effectively eliminated in the most appropriate place in time, intelligentized and networked train working condition on-line monitoring can be realized, and operation reliability and safety of rail transit can be finally improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to an on-line monitoring method for vehicle operating conditions of rail transit. Background technique [0002] With the continuous development of cities and the rapid progress of society, rail transit has entered a stage of comprehensive development. In the field of rail transit technology, rail transit vehicles (or trains) are an important and key component, which undertakes the important task of carrying and transporting passengers, and the operating conditions and safety conditions of each vehicle directly affect the normal operation of the entire rail line. operate. At the same time, the speed of vehicles is getting faster, the structure is more and more complex, the functions are more and more diverse, and the degree of automation is getting higher and higher, which puts forward higher requirements for the reliability and safety of vehicles. Among them, the ...

Problems solved by technology

For vehicles with data exchange functions between trains and ground, the information transmitted is generally train-level diagnostic fault information; for vehicles without data exchange functions between trains and ground, fault information cannot be sent to the ground, but can only be stored on the vehicle

The vehicle condition detection system of this embodiment has the following deficiencies in practical application: (1) the train level detection system collects the various information of the more detailed system of each component subsystem, if there is a large fault information, then send to the train control system , the train control system or fault representation is performed by the train control system; (2) If there is a functional system that transmits the train fault situation to the ground, only the fault information is transmitted, and the ground maintainers get the data of the result of the fault event, without the early warning function ; (3) The sub-level detection system of the train can only deal with some relatively primary direct or apparent fault information, and the advanced, complex or deep-level fault information analysis needs to be performed after the vehicle exits the operation (that is, offline). diagnosis

The fault data of the diagnostic system and its environmental parameters or tracking parameters are all stored in the on-board equipment in the form of a database. After the train stops operating, it needs to be downloaded to the fault analysis system for maintenance to analyze the cause of the fault in detail. Therefore, the vehicle operating condition detection Efficiency and intelligence are limited; (4) The operating condition detection system of each vehicle is relatively independent, and the vehicle operating condition detection system is basically terminated in the vehicle, so it is difficult to form an effective system closely related to rail transit operation
