Abstract

The invention provides a locomotive pantograph-catenary hard point photoelectric vibration comprehensive detection and GPS positioning method. The method includes steps: conversion from arc light to electric signals, analysis and processing of the electric signals, analysis of vibration signals, obtaining of a hard point value via calculation, and GPS accurate positioning. A locomotive pantograph-catenary hard point photoelectric vibration comprehensive detection and GPS positioning system mainly comprises a photoelectric sensor, an acceleration sensor, a signal conditioning device, an isolation transformer, an acquisition card, a control computer, a display, a memory, and a GPS positioner. According to the method and the system, acceleration detection of the hard point and photoelectric detection of the hard point are effectively combined, more accurate discrimination of the hard point can be made via double discrimination, accurate positioning of the hard point of a contact system is realized by employing an advanced GPS positioning module, the search and maintenance of faults are simple, and failure to adapt to the development requirement of high-speed rails and false and missed judgments can be avoided.

Description

technical field [0001] The invention belongs to the technical field of pantograph-catenary hard-point detection technology of a locomotive, and in particular relates to a photoelectric vibration comprehensive detection and GPS positioning method and system for a pantograph-catenary hard point of a locomotive. Background technique [0002] The large-scale development of high-speed railways has made electric traction locomotives with the advantages of high power, strong overload capacity and fast speed an inevitable trend of development. One of the main factors of the pantograph-catenary relationship, its occurrence will cause damage to the pantograph, catenary, locomotive electrical appliances, traction motors, traction transformers and the entire locomotive power supply system. In the appendix of the notice of Tieyun [2007] No. 69 "Catenary Operation and Maintenance Regulations", the provisional evaluation standards for catenary dynamic detection items are stipulated. Class...
