Abstract

The invention relates to the technical field of rail contact network detection equipment and discloses a non-contact contact network parameter acquisition device using a digital laser technology, a measuring system and a measuring method thereof. On one hand, under the condition of not stopping a data acquisition vehicle, rod number data closest to a contact network support rod can be automatically determined according to the recognition result of the contact network support rod and the real-time driving range; and on the other hand, contact network parameters comprising contact network lead pull-out value, lead height and the like can be acquired through calculation and by combining a laser scanner, a rail distance sensor and an inclination angle sensor, data storage and data display canbe automatically conducted and the failure position can be found through data overrun detection, so that the detection efficiency is further improved, the time is saved and the labor cost is reduced.In addition, through an in-built measuring data playback software system, the application aims of performing data playback, data analysis and data correction on the measuring data can be fulfilled, and automation of the later data analysis is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of track catenary detection equipment, and in particular relates to a non-contact catenary parameter acquisition device, a measurement system and a measurement method using digital laser technology.
