Abstract

An optical fiber type comprehensive on-line real-time pantograph detection and control system disclosed by the invention relates to the comprehensive on-line real-time pantograph detection and control technology for railway locomotives, subway cars, electric multiple units or the like, and belongs to the field of safe train running monitoring. The invention integrates an optical fiber type on-line real-time carbon pantograph slider abrasion detection system and an optical fiber type on-line real-time pantograph lifting pressure detection system together. The optical fiber type on-line real-time carbon pantograph slider abrasion detection system is used for detecting the abrasion of a carbon pantograph slider. The optical fiber type on-line real-time pantograph lifting pressure detection system is used for measuring the lifting pressure value Fc of the carbon pantograph slider. An air bag control valve is controlled according to a preset criterion to adjust the lifting pressure Fc and contact state of the carbon pantograph slider in order to prevent disconnection, lifting and other circumstances, and meanwhile, the detection systems can be utilized to prolong the service life of the carbon pantograph slider and increase the current-receiving quality of trains, thus guaranteeing the safe running of trains.

Description

technical field [0001] The invention relates to a pantograph comprehensive online real-time detection and control technology based on the principle of optical fiber transmission, in particular to a pantograph comprehensive online real-time detection and control technology for railway locomotives, subway vehicles or EMUs, etc., which belongs to the safe running of trains monitoring field. Background technique [0002] Optical fiber sensing is a new type of sensing technology that is currently developing rapidly. It has the advantages of good insulation, anti-electromagnetic interference, environmental corrosion resistance, high sensitivity, long transmission distance, and smart structure; The wear and contact force state of the bow carbon slide plate are the core issues of the bow-net relationship of railway locomotives or subway vehicles or EMUs, etc. The real-time online detection system adjusts the good contact between the pantograph and the catenary in time according to ...
