Abstract

The invention discloses a railway infrastructure detection system. The system involves a positioning synchronization subsystem, and a rail geometry detection subsystem, a rail contour detection subsystem, a rail state detection subsystem, a rail wheel force detection subsystem, a catenary geometric parameter detection subsystem, a pantograph-catenary current collection parameter detection subsystem which are in communication with the positioning synchronization subsystem. According to the system, on the basis of the structural characteristics and operation modes of urban rail transit infrastructure, the plurality of detection subsystems are integrated on a urban rail transit electric bus, rail geometric parameters, rail contour abrasion, rail state information, rail wheel interaction force, catenary geometric parameters and pantograph-catenary current collection parameters of the urban rail transit infrastructure are synchronously collected and accurately measured, the detection efficiency is improved, the urban rail transit operation maintenance cost is reduced, and the system can be widely applied to urban rail traffic construction and operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a railway infrastructure detection system. Background technique [0002] Urban rail transit is playing an increasingly important role in leading and supporting urban development, satisfying people's travel requirements, alleviating traffic congestion, and reducing air pollution. It has become the preferred public transportation method for daily travel in large cities. In recent years, my country's urban rail transit has developed rapidly. While the operating mileage and passenger flow have increased rapidly, the pressure and challenges for the safe operation of urban rail transit have also increased. The safety assessment of rail lines, wheel-rail relationship, pantograph-network relationship, and communication signals before operation and the daily dynamic inspection after operation play an important role in ensuring the safe operation of urban rail transit. [0003] The i...
