Monitoring system for rail transit bow net operating condition

Abstract

The invention provides a monitoring system for rail transit bow net operating condition, and belongs to technical field of rail transit detection. The monitoring system comprises a vehicle-mounted terminal, a ground testing center and a data communication network used for data transmission of the vehicle-mounted terminal and the ground testing center. The vehicle-mounted terminal comprises a vehicle-mounted data acquisition module, and a vehicle-mounted analyzing and warning module. The vehicle-mounted data acquisition module is used for acquiring bow net operating information from a bow net system to monitor bow net operating condition of the bow net system and acquiring general information of train operation. The vehicle-mounted analyzing and warning module is used for storing bow net operating condition and general information of train operation, and performing online analyzing and processing based on images and general information of train operation so as to judge whether operating condition is abnormal or not and send warning messages when operating condition is judged to be abnormal. The ground testing center performs association analyzing processing to bow net operating condition according to images and train operation general information from one or a plurality of vehicle-mounted terminals.

Description

technical field [0001] The invention belongs to the detection technical field of rail transit, and relates to a pantograph-catenary working condition monitoring system of a pantograph-catenary system of rail transit. Background technique [0002] At present, most rail transit systems use electric-driven trains. Usually, the transmission conditions of rated voltage / current are formed through the catenary system, and then the pantograph components of the train are used to receive the current to the power distribution system of the train for application. Train running provides energy. Thus, the interaction between the pantograph and catenary forms the link between ground-fixed power supply equipment and mobile vehicle applications, and the two primarily constitute what is commonly defined as a "panto-catenary system". [0003] While the pantograph-catenary system forms an electrical circuit, the catenary and the pantograph must maintain a good dynamic connection condition duri...

Problems solved by technology

[0007] First, due to the long running time of the train, the amount of recorded video data is very large. It is difficult, time-consuming, cumbersome to operate and extremely inefficient to judge the phenomenon of arcing only by manual review;

[0008] Second, manual review and judgment of the phenomenon of arcing is highly subjective, and it is easy to lead to inaccurate judgments;

[0009] Third, the monitoring of all pantograph-catenary conditions is completed after the train is running, and there is no real-time online monitoring function, so it is difficult to detect or predict the failure of the pantograph-catenary system in a timely and effective manner. When the working condition of the pantograph-catenary network is poor, it is likely that the trains passing by in the subsequent operation have failed due to the poor working condition of the pantograph-catenary network.
