Vehicle working condition online monitoring system for rail transit

Abstract

The invention provides a vehicle working condition online monitoring system for a rail transit, and belongs to the technical field of rail transits. The monitoring system provided by the invention comprises a vehicle working condition data acquisition module, a composite sensor, a vehicle-mounted working condition information preprocessor, a driver information display system, a regional information processor, a ground center information processor and a network communication transmission system; and the fault region of a vehicle can be divided into a primary level, a regional level and a central level, and the state data can be sent to the ground through the network communication transmission system, so that the fault of the primary level is analyzed and processed through the correspondingvehicle-mounted working condition information preprocessor, the fault of the regional level is analyzed and processed through the regional information processor of the corresponding ground, and the fault of the central level is analyzed and processed through the ground center information processor of the corresponding ground. Therefore, different fault types can be timely and effectively solved at the most proper places, networking and intelligence of the monitoring system are realized, and running reliability and safety of the 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 online monitoring system 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 o...

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
