Abstract

The invention provides a high-speed positioning method and device for a comprehensive inspection vehicle contact network inspection system. Both sides of the inspection vehicle roof are provided with at least two laser displacement sensors. The high-speed positioning triggering method comprises the steps of acquiring measurement data of the laser displacement sensors according to a sampling interval; at an interval of a fixed distance, recognizing a height range of a positioner according to the measurement data acquired within the fixed distance; judging whether the laser displacement sensor positions a positioner or not according latest measurement data of N sampling points and the height range of the positioner, and if a positioner is positioned, generating a first triggering pulse; and triggering a camera shooting assembly to perform image acquisition according to the first triggering pulse. According to the invention, positioners on a contact network can be accurately positioned, an accurate triggering pulse can be provided for the camera shooting assembly, occurrence of false triggering and missed triggering is reduced, and the interference resisting capacity is improved.

Description

technical field [0001] The application belongs to the field of catenary inspection, and in particular relates to a high-speed positioning and triggering method and device for a catenary inspection system of an integrated inspection vehicle. Background technique [0002] The comprehensive inspection vehicle catenary inspection system is a catenary suspension state detection and monitoring device (4C) installed on the comprehensive inspection vehicle, which mainly includes subsystems such as high-definition imaging detection, geometric parameter measurement, and positioner slope detection. The high-definition imaging detection subsystem uses a high-definition camera to collect images of the catenary detection area and output high-definition images. The imaging range should cover the catenary suspension equipment along the line. Among them, the catenary detection area mainly includes two types of equipment: positioning support device and contact suspension parts. The high-defi...
