The invention provides a dynamic localizer slope defect detection method and system. The method comprises the steps of collecting a real-time dynamic localizer slope numerical value at the positioning point and an operation speed per hour of an inspection van; calculating and obtaining the contact line allowable uplift at the positioning point according to the highest designed operation speed of a detection circuit and the operation speed per hour of the inspection van; obtaining the large slope defect threshold value of a dynamic localizer through the an allowable slope range threshold value of a static localizer; obtaining the smaller defect threshold value according to the allowable slope range threshold value of the static localizer, the contact line allowable uplift at the positioning point and the related information of the localizer; and comparing the real-time dynamic localizer slope numerical value at the positioning point with the large defect threshold value and the smaller defect threshold value respectively and obtaining the slope defect state of the dynamic localizer at the positioning point.
Description
technical field [0001] The invention relates to the technical field of electrified railway catenary detection, in particular to a method and system for detecting slope defects of a dynamic locator. Background technique [0002] The locator is one of the parts closest to the pantograph during train operation; when the train passes at high speed, the contact wire and the locator will be lifted to a certain extent under the contact pressure between the pantograph and the catenary. Therefore, the locator The structure and state of the device (locator, positioning tube, etc.) should ensure that when the pantograph passes the positioning point, the contact line can be lifted freely within a certain range without obvious hard points. In order to avoid collision with the locator when the pantograph passes Catenary operation accidents caused by bowing have certain requirements on the slope range of the locator. Therefore, the detection of the slope of the locator is an important safe...
