Rail transit pantograph-grid operation condition monitoring system

Abstract

The invention relates to a rail transit pantograph-grid operation condition monitoring system comprising a bearing base, a distance measuring device, a CCD industrial camera, a multispectral sensor, afar-infrared temperature measuring device, a pressure sensor, a stroke sensor, an angle sensor, a wind pressure measuring instrument, and a control device. The bearing base is a frame structure witha rectangular cross section, and is installed on the outer surface of the top of a rail transit train. The bearing base and the pantograph of the rail transit train are coaxially distributed. The bearing base comprises a chassis, a lifting drive mechanism, and the worktable. The pressure sensor, the angle sensor and the stroke sensor are all mounted on a driving mechanism of the pantograph of therail transit train. The CCD industrial camera, the multispectral sensor, the far-infrared temperature measuring device and the wind pressure measuring instrument are connected with the upper end surface of the worktable. The monitoring system is simple in structure, reasonable in layout, high in degree of integration, high in degree of automation, good in universality, comprehensive in detection and good in data communication capability, and can greatly improve the reliability and the stability of the rail transit train in operation.

[0002] Among all kinds of rail vehicles, the operation stability and reliability of the pantograph-catenary mechanism are the necessary basic conditions to ensure the safe and reliable operation of the rail vehicles. In order to improve the operation stability of the pantograph-catenary mechanism, all rail vehicles are It is a special monitoring system for pantograph-catenary mechanism operation status detection, but in use, it is found that the currently used monitoring systems are often based on pressure sensors, temperature sensors and other equipment as detection equipment, although these equipment can meet the requirements of use to a certain extent. It is necessary, but the current various detection equipments have relatively poor data types and monitoring accuracy capabilities to varying degrees on the one hand, and cannot effectively meet the comprehensive detection of factors that affect the operation of the pantograph-catenary mechanism due to terrain changes, airflow changes, etc. It is also impossible to timely and effectively detect the interference of high temperature factors and freezing factors, which also has a great impact on the stability and reliability of rail vehicles. In the operation of vehicles, the operation status of the pantograph-catenary mechanism is effectively detected in the whole process, which will greatly affect the stability and reliability of the current rail vehicle equipment. Therefore, in view of this situation, it is urgent to develop a new type of bow Network mechanism operation status detection device to meet the needs of rail transit equipment operation
