Problems solved by technology

With the development of urban rail transit, the operation safety of trains is becoming more and more important. Due to the high requirements of operation safety, trains must be equipped with reliable derailment detection devices. At present, derailment detection devices include contact and non-contact, contact derailment There is a risk of damage to the bogie through the collision detection with the rail surface, and the non-contact method has become the leading research direction. At present, various non-contact detection methods have reliability and false alarm risks

Abstract

The invention discloses an urban rail train derailment detection method, a derailment detection system adopted by the method comprises a control unit and a derailment detection equipment unit, the control unit is connected with the derailment detection equipment unit through a cable, the control unit is installed in each carriage, the derailment detection equipment unit is installed on a bogie of each carriage and comprises a fixing and height adjusting mechanism, a bearing structure and an eddy current sensor; the fixing and height adjusting mechanism is connected with the bearing structure through bolts, and the eddy current sensor is connected with the bearing structure through bolts. A non-contact derailment detection method is adopted, the detection method of the detection device is improved, meanwhile, due to reasonable arrangement of the whole vehicle, the detection reliability is improved, and misinformation is avoided.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a method for detecting derailment of urban rail trains. Background technique [0002] With the acceleration of urbanization, the demand for urban transportation continues to increase, and urban rail transit is playing an increasingly important role in the field of public transportation. With the development of urban rail transit, the operation safety of trains is becoming more and more important. Due to the high requirements of operation safety, trains must be equipped with reliable derailment detection devices. At present, derailment detection devices include contact and non-contact, contact derailment There is a risk of damage to the bogie through the collision detection with the rail surface, and the non-contact method has become the leading research direction. At present, various non-contact detection methods have reliability and false alarm risks. Contents of th...
