A Track Parameter Measurement System

Abstract

The invention discloses a rail parameter measuring system. A first processing device of a first measuring trolley processes digital images which are taken by a camera shooting device, therefore, a corresponding rail parameter value is calculated. A sensor assembly measures parameters including a rail gauge, a first measuring trolley horizontally inclined angle and a walking mileage. Light-emitting targets of a second measuring trolley coordinate with camera shooting measurement of the camera shooting device, an electronic total station measures a coordinate position of the second measuring trolley in a measurement control network, a second processing device controls the measuring process of the electronic total station and reads measuring data of the electronic total station, a second sensor assembly measures parameters including a rail gauge, a horizontally inclined angle of the second measuring trolley and a walking mileage. The first measuring trolley and the second measuring trolley achieve mutual exchange of measured data through a first data transfer radio and a second data transfer radio. The rail parameter measuring system can achieve target dynamic tracking measurement, enables the images to be conveniently monitored and displayed, and can effectively solve the problems that an existing device has difficulty in alignment and operation is not convenient to conduct.

Description

technical field [0001] The invention relates to a track parameter measurement system, in particular to a portable track parameter measurement system applied to the measurement of railway track curve parameters in the field of rail transportation. Background technique [0002] Under normal conditions, there is always a certain error between the static curve shape of the railway track and its design value, and the existence of the error makes the actual value of the rail track a curve that fluctuates around its design value. Therefore, in order to improve the measurement accuracy of orbital curve parameters and suppress long-wave errors in orbital parameter measurement, it is necessary to establish an orbital measurement control network, and use the corresponding measuring instruments to measure orbital parameters based on the measurement control network. [0003] At present, there are several track parameter measurement systems based on the measurement control network in the ...
