Problems solved by technology

However, the absence of small steps on the switch operating current curve may also be caused by the open circuit of the diode branch in the junction box outside the switch machine. Therefore, the specific fault type of the switch machine cannot be accurately determined through the switch operating current curve.

Abstract

The embodiment of the present invention provides a fault type diagnosis system and method of a switch machine. An angle sensor is introduced to measure the angle between the moving contact and the matching designated static contact, so that the detection of the moving contact can be realized, and the data processing module is adopted By processing and analyzing the measurement results, the accurate determination of the fault type of the switch machine can be realized.

Description

technical field [0001] The invention relates to the technical field of rail transit safety, and more particularly, to a system and method for diagnosing fault types of switch machines. Background technique [0002] At present, in rail transit, turnouts play an important role. A turnout is a line connection device that allows a train to transfer from one track to another, and is usually laid in large numbers at stations and marshalling yards. The switching and locking of the turnout is controlled by Computer Based Interlocking (CBI), which controls the rotation of the switch machine and then drives the turnout to realize switching and locking. [0003] The switch machine has a turnout display function. The turnout display function means that after the turnout is switched to the reverse position, combined with the mechanical and electrical devices, the position information of the turnout is reflected to the computer interlocking, and then the train route arrangement is realiz...
